Technical field

The present invention relates to a kind of air-conditioning equipment and method of operating thereof.More particularly, the present invention relates to a kind of air-conditioning equipment and method of operating thereof, the operation of wherein can in very wide temperature range, under the very little situation that is cooled to very little heating, drying.

Background technology

To reduce traditional air-conditioning equipment of humidity, a kind of known system is arranged as the operation of drying therein, wherein heated again by an electric heater by the air that evaporimeter cooled off; Also have a kind of system, wherein air is heated by the condensation heat of refrigerant cycles again.When these two systems were compared mutually, particularly from energy-conservation angle, the latter was considered to preferably, because the former will consume a large amount of electric energy.

In addition, disclose in 60-181559,2-183776,3-31640 and 51-18059 number in Japanese patent unexamined, described the example of refrigerant cycles, wherein cooled air is heated by refrigerant cycles itself again in the operation of drying.

Wherein, Japanese patent unexamined discloses 60-181559 number and discloses a kind of EGR, wherein compressor, cross valve, outdoor heat converter, flow controller and indoor heat converter interconnect successively by refrigerant pipeline, and indoor heat converter is divided into two parts, and is connected in parallel betwixt to be useful on the dry throttling arrangement and the two-way valve that is used for this throttling arrangement that dries of bypass of the operation of drying.And, in the operation of drying, can be by closing described two-way valve so that refrigerant flows into the choke valve that dries, make at indoor separated upstream side and become a condenser and its downstream becomes an evaporimeter, and allow indoor air stream after the device that is condensed cools off and dries, to flow into this condenser it is heated again with evaporimeter from this evaporimeter, thereby excessively do not reducing under the situation of temperature the operation of drying.

Japanese patent unexamined discloses 2-183776 number and has further adopted a kind of aperture two-way valve, and so that a kind of EGR to be provided, wherein indoor heat converter is divided into upper and lower part.In the operation of drying, separated top is used as condenser, and its underpart is used as evaporimeter.In addition,, can make this operation of drying,, reduce humidity again with evaporimeter air being cooled off and drying and when it being heated, both prevented sub-cooled with condenser by making room air and these indoor heat exchanger PARALLEL FLOW.

Japanese patent unexamined discloses 3-31640 number, disclose in Japanese patent unexamined on the basis of 60-181559 number device, a kind of channel switch device further is provided, it comprises four check-valves, even so that air stream also can one side flow to heater from evaporimeter in the room when cross valve is switched to heat cycles, thereby a kind of EGR is provided, in this device, can have carried out the operation of drying by force of very little heating.In addition, by the caloric value that the revolution speed control device by outdoor fan comes the control room outer heat-exchanger, can regulate the air heat amount at indoor heat converter place, thereby room temperature is remained on predetermined value.In addition, in the description of this prior art, outdoor fan carries out very weak operation when outside air temperature is no more than 22 ℃, and carries out weak operation when being not less than 22 ℃.

Do not examine to disclose in the EGR of being announced for 51-18059 number in Japanese Utility Model, provide two compressors, but its circulation is identical with the circulation that Japanese patent unexamined discloses described in 60-181559 number basically.In this operation method, outdoor fan and compressor are controlled according to operating function, rather than control according to outdoor temperature.For example, outdoor fan is low cruise in low cooling dehumidification operation, and is stopped in operation is dried in low heating.In addition, one of compressor operation in the operation of drying.

Recently, the tendency of operation that dries is used for multiple purpose.For example, have: (1) happiness operation of drying, in its rainy season not high in temperature but that have a humid climate, when keeping the temperature of setting, dry; (2) " good night "/" good morning " operation of drying, it can not have under the very low state of air-flow sense and noise at sultry night or early morning, promoted happy sleep by reducing humidity and don't excessively reducing temperature; (3) mould/tick operation that prevents to dry, it is by being maintained at about relative humidity 50% propagation that prevents mould and tick; (4) the laundry operation of drying, it is used to make the clothing of being washed can be in the indoor drying that obtains in rainy season.Yet, four disclosed in any one at this, all consider to adopt to satisfy the operation method of application target (1) to (4).

Disclose in 3-31640 number in Japanese patent unexamined, though the air heat amount of in the operation of drying, regulating indoor heat converter by the revolution of control room external fan, but do not announce the operation of compressor, thereby it is not enough to satisfy the multiple purpose as above-mentioned (1) to (4).In addition, though extraneous air has been carried out two-stage control, thereby when making the operating in outside air temperature and be no more than 22 ℃ of outdoor fan very weak and when it is not less than 22 ℃ a little less than, it is not enough to control with respect to outdoor temperature.

In addition, though a lot of air-conditioning equipments are carried out cooling and heating operation beyond the operation of drying, as the refrigerant pipeline that makes the heat exchanger in the room that is connected in series of above-mentioned four dichotomic type heat exchangers described in open is oversize to cooling and heating operation.Especially, when adopting two heat exchangers as evaporimeter in the room, the compression losses of the cryogen flow of the heat exchanger in the chamber increases.If or else air stream and cryogen flow become convection current, perhaps in heating operation, do not carry out time cooling fully, the performance of refrigerant cycles will be lowered.In this regard, attempt in 2-183776 number to make two pipelines into by at least one coolant channel that makes the heat exchanger in the room though disclose in Japanese patent unexamined, to reduce the pressure loss, this remains not enough.And in other open, this problem is not mentioned.

In addition, as mentioned above, the operation of drying has been used to multinomial purpose recently.For example, have: (1) happiness operation of drying, it was used in the rainy season in early summer of the not too high but high humidity of temperature or autumn, and wherein drying is to carry out when temperature is remained on setting value; (2) " good night "/" good morning " operation of drying wherein in the night or the early morning of sultry and imperceptible air-flow, is not excessively reducing temperature with when guaranteeing the happiness sleep under the low noise state, the operation of drying; (3) mould/tick operation that prevents to dry wherein by relative humidity is maintained at about 50%, prevents that mould and tick from propagating; (4) the laundry operation of drying, it is ought be in aforesaid rainy season, is adopted when the clothes washed at the room inner drying.

Consider the running status of compressor and indoor fan and outdoor fan, in service " good night "/" good morning ", need to carry out the low air flow amount and go operation, wherein imperceptible air stream and humidity are enough under the low noise condition.In laundry operations, need the operation of drying of upper air current amount, wherein the air curtain coating reaches in the very big scope, and drying capacity is very high.Happiness dry or mould/tick prevent to dry the operation in, need suitably adopt the operation of drying under above-mentioned low air flow amount and the upper air current amount.In addition, also need, low air flow is measured or low cooling, low isothermal or low heating operation are carried out in the operation of drying of upper air current amount according to room temperature.

To being used for the operation of drying of above-mentioned various uses, make an explanation below in conjunction with Fig. 2; Fig. 2 is the flow chart of expression operator scheme.As shown in Figure 2, send a demonstration, with expression forced movement or the beginning (200) of operation automatically, wherein the indoor and outdoors temperature and humidity has obtained detection; The operator scheme of drying is selected (201).According to this demonstration, select happiness operation (210), mould/tick operation (220), " good night "/" good morning " dry in the operation (240) etc. one of operation (230) and laundry that dries that prevents to dry that dries.In the case, if do not show concrete pattern, then select the happiness operator scheme (210) of drying automatically.

At first, under operation (210) is dried in happiness, carry out indoor temperature and Humidity Detection (211), with the setting (212) of carrying out required indoor temperature and humidity by Temperature Detector 17 and moisture detector 18.Subsequently, blowing condition to the room fan is set (213), determining that with the low air flow amount still be the operation of drying of upper air current amount, and select operation (214) or the upper air current amount operation (215) of drying of drying of low air flow amount according to this setting (213).Dry under the situation of operation carrying out happiness, need suitably set indoor temperature and humidity, so that the people feels happy.In this regard, this system obtains suitable design, controls with the thermal comfort index of basis such as PMV (the average abbreviation of selecting of prediction).If control is carried out according to this thermal comfort index, then not only to find out the temperature and humidity in room, but also will find out radiation temperature, wind speed, someone clothes amount, someone activity etc., and come automatic design temperature and humidity according to season, someone state, someone activity or the like of clothes.

In mould/tick prevents to dry operation (220), with the same in the operation (210) of drying in happiness, by Temperature Detector 17 and moisture detector 18, carry out the detection (221) of room temperature and temperature and the setting (222) of desirable room temperature and humidity.Subsequently, blowing state to room fan 12 is set (223), with the operation of determining to dry is carry out under low air flow amount or upper air current amount, and according to this setting (223), selects operation (224) or the upper air current amount operation (225) of drying of drying of low air flow amount.In this regard, known to prevent the propagation of mould and tick, relative humidity should remain in 40 to 60% the scope.Therefore, for the operation that prevents to dry of mould/tick, be preferably a humidity and be set in for example about 50% automatically regularly.By carrying out this operation of drying, can under the situation of temperature of remaining valid preferably, carry out this operation.

Under " good night "/" good morning " dried operation (230), carry out the detection (231) of room temperature and humidity by Temperature Detector 17 and moisture detector 18, and carry out the setting (232) of desirable room temperature and humidity.Subsequently, when the people began sleep and wakes up in the morning, the people can not sleep under the situation that the people feels uncomfortable or noise is big owing to making at air stream, by reducing the blowing ability of room fan 12, the operation (233) of drying is carried out under low air flow amount state.In this regard, the comfortable room temperature during sleep and the approximation of humidity are known.For example, in rainy season or sultry summer,, produce comfortable and healthy environment by excessively not reducing the situation decline low humidity of room temperature.Therefore, in " good night "/" good morning " dried operation, also can set room temperature and humidity by room temperature and humidity are fixed on these values automatically.In addition, under this operator scheme, can also adopt an automatic operation mode, this automatic operation mode obtains programming to be fit to people's sleep mode, promptly when the sleep beginning, can change when waking up in the morning in the deep sleep neutralization.

In operation (240) is dried in laundry, detect (241) by the temperature and humidity of Temperature Detector 17 and 18 pairs of space airs of moisture detector, and desirable room temperature and humidity are set (242).Subsequently, in the laundry drying, for make the air curtain coating reach on a large scale in to strengthen dehumidification ability, in the blowing ability that increases room fan 12, carry out the operation (243) of drying of upper air current amount.In addition, when the cloth drying washed, but different with the human body sensory of slight change, temperature and humidity can be configured to constant substantially.Thereby in operation was dried in laundry, room temperature and humidity also can obtain fixing automatically and set.

In these areas, under the operator scheme that is used for each purposes as shown in Figure 2, room temperature and Humidity Detection (211), (221), (231) and (241), room temperature and humidity are set (212), (222), (232) and (242), room blowing setting state (213) and (223), not necessarily to carry out in proper order, and can be optional setting according to this.

In each above-mentioned purposes, operator scheme is divided into low air flow amount dry operation and the operation of drying of upper air current amount substantially.The use of air conditioner itself, also be to dry and operate and do washing and dry in the operator scheme of the various uses operating to prevent from the to dry operation, " good night "/" good morning " of the operation of drying such as happiness, mould/tick, carry out by these low air flow amounts are dried operation and the upper air current amount operational applications of drying.

Dry and operate in dry operation and upper air current amount of aforesaid low air flow amount, if the detected value and the setting value of room temperature differ from one another, then according to this temperature difference " Δ T " (with " and Δ T=detects room temperature-settings room temperature and represents); need be in that " Δ T hangs down cooling dehumidification when higher and operates for just promptly detecting room temperature, " Δ T approximates zero and hang down the isothermal operation of drying when being both approximately equals, and " Δ T for negative be that detected temperatures is hanged down when hanging down and heated the operation of drying.These methods of operating will obtain describing in detail below.

As from show the low air flow amount dry operation method of operating Fig. 3 as seen, the room fan is set at low air quantity operation (301) earlier.Subsequently, the room temperature that the Temperature Detector in the room 17 detects is compared with the room temperature of setting, and " Δ T is timing, carries out a low air flow amount and a low cooling dehumidification operation (310) when temperature difference.In the case, compressor 1 is set at low ability operation (311), because if ability is lowered and has just kept dehumidification ability completely.In addition, in order to carry out cooling down operation, need to increase the heat-sinking capability of outdoor heat converter 3 and reduce the indoor heat converter 6a that is used as heater heating efficiency, also need to make the high gas flow ability of outdoor fan 10 to obtain increasing (312) for this reason air stream 15.

If temperature difference " Δ T " approximates zero, then carry out the operation (320) of drying of low air flow amount and low isothermal.In service at this, compressor 1 is set at low ability operation (321), because if ability is lowered and can obtains the operation of drying completely.In addition, in order to hang down isothermal operation, need be set in the heat-sinking capability of outdoor heat converter 3 mediumly, and will be set in mediumly as the indoor heat converter 6a of heater to the heating efficiency of air stream 15, and the blowing ability of outdoor fan 10 is set to medium (322) for this reason.

If temperature difference " Δ T " is then carried out low air flow amount heating operation (330) for negative.In this operation, need to reduce the heat dissipation capacity of outdoor heat converter 3, and increase is used as the heating efficiency of the indoor heat converter 6a of heater to air stream 15.For this reason, the blowing ability of outdoor fan 10 is reduced and outdoor fan is stopped (332) when needed widely.In addition, though obtained dehumidification ability completely by the ability that reduces compressor 1, the ability that can pass through to increase compressor 1 is carried out heating operation to increase the ability of heater 6a.Therefore, the ability of compressor strengthens (331) with degree of heat.

In order to describe the concrete example of operation that the low air flow amount is dried and operated here, wet in the chamber is 24 ℃, room relative humidity is 60%, outdoor temperature is that 24 ℃ and outside humidity are under 80% the condition, be cooled to the room air conditioner of 2.8KW with standard, fully reduced and the space air flow is set at about 2m at the outdoor air flow 3The theoretical discharge rate of/min and compressor is 0.98m 3Under the situation of/h, can under about 21 ℃ blowing temperature, hang down cooling down operation.When theoretical discharge rate is 1.5m 3During/h, can carry out heating operation being about under 27 ℃ the blowing temperature.Therefore, can carry out operating the temperature of wherein the drying low heating higher 3 ℃ operation of drying than room temperature from the blowing temperature low cooling dehumidification lower 3 ℃ of indoor unit wherein than room temperature.

In this regard, in aforesaid low air flow amount was dried operation, though that the ability of compressor 1 is set to is low owing to having obtained completely the amount of drying, it was not limited only to this, and the ability of compressor can be enhanced.In the case, input is increased but dehumidification ability is increased gradually greatly.

Below, in conjunction with Fig. 4, the dry method of operating of operation (350) of upper air current amount is described.At first, room fan 12 is arranged on upper air current amount operation (351).Subsequently, the room temperature that Temperature Detector 17 detects is compared (352) with the room temperature of setting, " Δ T is timing, carries out a upper air current amount and a low cooling dehumidification operation (360) when temperature difference.In this operation, because room fan 12 is in upper air current amount operation, compressor 1 must be in high ability operation (361) and obtain dehumidification ability completely with the evaporating temperature of the indoor heat converter 6b that is used as evaporimeter by reduction.In addition, in order to hang down cooling down operation, need to increase the heat-sinking capability of outdoor heat converter 3 and reduce the indoor heat converter 6a that is used as heater heating efficiency air stream 15.For this reason, the blowing ability of outdoor fan 10 obtains increasing (362).

If " Δ T is approximately zero to temperature difference, then carries out the operation (370) of drying of upper air current amount and low isothermal.In this operation, because identical in the above-mentioned cooling down operation, compressor 1 is set at high ability operation (371).In addition,, need set the heat-sinking capability of outdoor heat converter 3 for mediumly, and be set at the indoor heat converter 6a that is used as heater medium to the heating efficiency of air stream 15 in order to carry out low isothermal operation.For this reason, the blowing ability of outdoor fan 10 is set to medium (372).

If temperature difference " Δ T ", is then advanced a upper air current amount and the low heating operation (380) of drying for negative.In this operation and since with low cooling and low isothermal operation in identical, compressor 1 is set at high ability operation (381).In addition,, need to reduce the heat dissipation capacity of outdoor heat converter 3, and increase is used as the heating efficiency of the indoor heat converter 6a of heater to air stream 15 in order to carry out heating operation.For this reason, the blowing ability of outdoor fan 10 be greatly diminished and when needed outdoor fan 10 be stopped.

In order to describe the concrete example of operation that the upper air current amount is dried and operated at this, for example, in room temperature is 24 ℃, room humidity is 60%, outdoor temperature is that 24 ℃ and outside humidity are under 80% the condition, adopt the room air conditioner of 2.8KW standard cooling capacity, when the outdoor air flow is fully reduced and the room air flow is approximately 6m 3/ min, and the theoretical discharge rate of compressor is 1.9m 3During/h, the temperature of drying is approximately 26.5 ℃ low heating operation.Thereby, can realize the low heating operation of drying, wherein the blowing temperature of indoor unit is higher 3 ℃ than room temperature.

In this regard, in the upper air current amount was dried operation, because compressor 1 is set at high ability operation, input had obtained increase.Fig. 5 is a side view cutaway drawing, has shown an indoor unit, and this indoor unit can solve the problem that this input increases; Fig. 6 is the dry flow chart of method of operating of upper air current amount.

In Fig. 5, identical parts in label 6a, 6b and 12 expressions and the EGR shown in Figure 1.They are respectively at the heat exchanger of the upstream side of the heat exchanger in the downstream of air, air and room fan.In addition, label 31 expression air inlet fence, label 32 is the shells on the rear side, wherein is formed with air duct.Label 33 expressions one condensed water dash receiver, 34 is the air doors that can open and close, and 35 expressions are contained in the air duct on the top of shell 32.By adopting such device, heat exchanger 6b becomes an evaporimeter and indoor heat converter 6a becomes a heater, thereby make room air be transplanted on air stream 37 from air stream 36 as shown by arrows by operation room fan 12, make air stream 36 by air inlet fence 31, and it is after being cooled off by evaporimeter 6b and drying, and 6a heats by heater.It is blown out along direction shown in the arrow by room fan 12 and quilt subsequently.In addition, the condensed water that produces in evaporimeter 6b is received and is discharged into outside the room by plate 33.

Below, will be in conjunction with the flow chart of Fig. 6 and with reference to as shown in fig. 1 EGR, the upper air current amount that the adopts indoor unit as shown in Figure 5 method of operating of drying is described.

When selecting the upper air current amount to dry pattern (400), air-breathing air door 34 at first is opened to the position (401) shown in 34a, so that room fan 12 operates under the upper air current amount state (402).Subsequently, compare with the room temperature of setting in the room temperature that Temperature Detector 17 detects, " Δ T " is timing when temperature difference, carries out a upper air current amount and a low cooling dehumidification operation (410).In this operation, because the room fan moves with the upper air current amount, this air mass flow is the air mass flow and the air mass flow sum of passing through indoor heat converter 6a and 6b by air duct 35.Air mass flow by indoor heat converter 6a and 6b is lowered, even and compressor 1 be set at low ability operation, the evaporating temperature of evaporimeter 6b also is lowered, to obtain dehumidification ability completely.In addition, in order to hang down cooling down operation, need to increase the heat-sinking capability of outdoor heat converter 3 and reduce the indoor heat converter 6a that is used as heater heating efficiency air stream 36.For this reason, the blowing aptitude of outdoor fan 10 is in increasing (412).

If temperature difference " Δ T " is approximately zero, then carry out the operation (420) of drying of upper air current amount and isothermal.In this operation and since with cooling down operation in identical, compressor 1 is set at low ability operation (421).In addition, in this low isothermal operation, the heat-sinking capability of outdoor heat converter 3 need be set at the medium and indoor heat converter 6a that will be used as heater and be set at medium the heating efficiency of air stream 36.For this reason, the blowing ability of outdoor fan 10 is set at medium (422).

, then carry out the upper air current amount and heat the operation (430) of drying for negative as if temperature difference " Δ T " with hanging down.In this operation, because with identical in low cooling and low isothermal operation, compressor 1 also is set at low ability operation (431).In addition, in order to hang down heating operation, need to reduce the heat dissipation capacity of outdoor heat converter 3 and increase the indoor heat converter 6a that is used as heater heating efficiency air stream 36.For this reason, the blowing ability of outdoor fan 10 be greatly diminished and where necessary outdoor fan 10 be stopped (432).

In this regard, can use the mode identical, carry out the low air flow amount operation of drying with the method for operating shown in Fig. 3.And, the air door that in Fig. 5, that label 34 is shown as is rotating, can open and close, but it is not limited in this.As long as adopt a kind of structure that can be opened and closed just enough.In addition, though in the description in front, detection to room temperature and humidity is undertaken by step described in conjunction with Figure 2, it is not limited in this, and it can carry out before in comparison (302), (352) or (403) that the room temperature to the room temperature that detects and setting shown in Fig. 3,4 and 6 is carried out.

In addition, in Fig. 7 and 8, shown another embodiment of the present invention.Fig. 7 is a structural representation, has shown according to of the present invention to circulate in outdoor part; And Fig. 8 is a flow chart, has shown a heat dissipation capacity control method of outdoor heat converter 3.

The part 40 of being surrounded by two dot dot dash among the outdoor section of circulation shown in Figure 7 and Fig. 1 is corresponding.In EGR shown in Figure 1, it is by 3 bypasses of outdoor heat converter and have the shunt valve 42 that passes through two-way valve 41.In addition, in Fig. 7, the identical identical part of label representative.

In air-conditioning equipment according to present embodiment with loop structure shown in Figure 7, though its method of operating is with identical in EGR shown in Figure 1, but the low air flow amount in step 332 shown in Figure 3 heats the operation (330) of drying with hanging down, upper air current amount in the step 382 shown in Fig. 4 heats the operation (380) of drying with hanging down, and at the upper air current amount and the low heating operation of step 432 shown in Figure 6, all in indoor unit structure shown in Figure 5, done following corresponding change, these changes are that the control method at the heat-sinking capability of outdoor heat converter 3 carries out, and these changes are as follows:

In operation is dried in low heating, heat dissipation capacity control method by outdoor heat converter shown in Figure 63, at first in order to increase the heating efficiency of the indoor heat converter 6a that is used as heater, the blowing ability of outdoor fan 10 is reduced widely or outdoor fan 10 is stopped (501).Subsequently, detect room temperature and it is set room temperature and compare with one, and, then open two-way valve 41 (503) if the detection room temperature is lower than the setting room temperature.In addition, when the detection room temperature is not less than the setting room temperature, sets and finish (504).The result, when two-way valve when step 503 is opened, because nearly all high temperature and high pressure cryogen flow of discharging from compressor 1 is not by outdoor heat converter 3 but flow into the indoor heat converter 6a that is used as heater, when two-way valve is closed when stopping outdoor fan 10, the heat that is dispersed in the atmosphere owing to free convection is brought among the indoor heat converter 6a, and add heat and further increased therein, heat the operation of drying thereby can hang down.

Though above description is for the drying operation in the EGR as shown in Figure 1, in the cycle performance and heat exchange performance of heat exchanger 6a that guarantees to be used for each cooling and heating operation and 6b, need effectively operate.Below this method will be described.

At first, in the embodiment in figure 1, owing to being divided into two part 6a and 6b and they, heat exchanger is connected in series, so at cooling down operation with in heating operation, particularly heat exchanger 6a and 6b all are in low-pressure state in cooling down operation by two-way valve 8.Because they are evaporimeters, the wherein very big and volume flow increasing of the specific volume of gaseous refrigerant is so the pressure loss in the heat exchanger increases and cycle efficieny descends.

Shown an embodiment that can address this problem among Fig. 9 and 10.Fig. 9 and 10 these embodiment that show are corresponding to the heat exchanger part of the room side part 90 of being surrounded by a little line among the embodiment of Fig. 1.Figure 10 is the plane of seeing from the arrow P direction of Fig. 9.In Fig. 9 and 10, label 51a and 51b are two heat exchangers that separate, and they are corresponding with part 6a and the 6b of Fig. 1.Room heat exchanger 51a has plumbing installation, and wherein it is divided into two system's refrigerant pipelines 52 and 53 at an A, and they are combined into single system at a B again.Similarly, heat exchanger 51b in room is divided into two system's refrigerant pipelines 54 and 55 at a C.Pipeline 54 and 55 is combined into triangular web at a D again.Label 56 expressions one radiator shutter, other parts of same numeral are represented identical parts in Fig. 1.

In having the air-conditioning equipment of said structure, when cooling off or during heating operation, by opening two-way valve 8, because refrigerant flows when being divided into two systems, in room heat exchanger 51a and 51b, there is half refrigerant to flow through in each system, and, prevented the reduction of efficient because the flow of refrigerant pressure drop among room heat exchanger 51a and the 51b reduces therefrom.

In this regard, though in the embodiment of Fig. 9 and 10, shown room heat exchanger 51a and the refrigerant pipeline of 51b are divided into two systems, and they are not limited in this situation, and they can be divided into plural system.Still in this regard, the flow of refrigerant droop loss can be lowered, and decrease in efficiency can be prevented from.Yet if cryogen flow is exceedingly separated, though the pressure drop of refrigerant reduces, it is obvious that the decline of its heet transfer rate also becomes.And the whole efficiency of air-conditioning equipment (such as cooling capacity and efficient) also can reduce.Thereby, needing to set best number of systems, this number is to be determined by the internal diameter of refrigerant pipeline.

Subsequently, in heating operation, in order to improve the efficient or the coefficient of performance such as heating efficiency, need be in being used as the room heat exchanger of condenser, the heat exchange section that high-temperature gas refrigerant is wherein flowed at their inlet, with they, wherein do not have heat exchange section to be carried out heat exchange by the air stream of the position, air downstream of heat exchange, and further make it and carry out heat exchange, thereby carry out sufficient sub-cooled at heat exchange section corresponding to the cryogen flow outlet at the air stream air upstream side, that have lower temperature.Shown the device that system is wherein designed like this among Figure 11.In Figure 11, label 60a represents a room heat exchanger, two system's refrigerant pipelines 61 that it is included in that an E and some F engage and 62.Label 60b represents a heat exchanger, two system's refrigerant pipelines 63 that it is included in that a some G engages and 64.Label 60c represents a room heat exchanger, two system's refrigerant pipelines 66 that it is included in that a some H engages and 67; Refrigerant is flow through and air stream 15 flows through in the air downstream after by room heat exchanger 60b at the upstream side of room heat exchanger 60b in heating operation.Label 60d represents to have the heat exchanger of refrigerant pipeline 65; The refrigerant that flows into refrigerant pipeline 65 becomes single system, and refrigerant pipeline 65 is arranged on such position, in this position, refrigerant flows through in the downstream of room heat exchanger 60a and air stream 15 directly is coupled with in heating operation, and this position is positioned at the upside of room heat exchanger 60b.Therefore, basically, this device is the device that wherein further heat exchanger 60c and 60d is added on the embodiment of Fig. 9.

In aforesaid air-conditioning equipment, refrigerant also sequentially flows by room heat exchanger 60c, 60b, 60a and 60d through two-way valve 8 in heating operation.Shown in dotted arrow, a high-temperature gas cryogen flow is carried out heat exchange at heat exchanger 60c and the air stream 15a that carries out heat exchange at room heat exchanger 60b, and further carries out heat exchange at heat exchanger 60b with the air stream 15 with lower temperature.And by carrying out heat exchange at heat exchanger 60a and the air stream 15a that has carried out heat exchange at room heat exchanger 60b, it obtains heat radiation, cooling and total condensation in the exit of heat exchanger 69a.Subsequently, the liquid cryogen of this condensation flow among the single system room heat exchanger 60d, to increase its speed, and abundant increase along with the heat-transfer rate in the pipe, this refrigerant carries out heat exchange with the air stream 15 with lower temperature, to become the state that sub-cooled is wherein fully carried out.In the case, the cryogen flow from room heat exchanger 60c to 60b becomes and air stream 15 and 15a convection current.And the cryogen flow from room heat exchanger 60a to room heat exchanger 60d becomes the convection current of flowing 15a and 15a with air.In all cases, all set up effective heat exchange condition.

In addition, in cooling down operation, shown in the solid line arrow, successively through room heat exchanger 60a, two-way valve 8, room heat exchanger 60b and flow to room heat exchanger 60, and all these room heat exchangers all are used as evaporimeter to refrigerant from room heat exchanger 60d.

In the operation of drying, shown in some dash-dot arrows, refrigerant flows to room heat exchanger 60c from room heat exchanger 60d through room heat exchanger 60a, the flow controller 7 that dries, room heat exchanger 60b.Room heat exchanger 60d and room heat exchanger 60a are used as heater, and room heat exchanger 60b and room heat exchanger 60c are used as cooler/moisture separator.In the case and since the room heat exchanger 60c that is used as cooler/moisture separator be positioned at the room heat exchanger 60a that is used as heater below, the water that dries that room heat exchanger 60c produces is by room heat exchanger 60a heating or evaporation again.In addition and since the room heat exchanger 60d that is used as heater be positioned at the room heat exchanger 60b that is used as cooler/moisture separator above, the water that dries is by room heat exchanger 60d heating or evaporation.

As from as seen above-described, in Figure 11, room heat exchanger 60c not necessarily to be positioned at room heat exchanger 60a below, but can be positioned at optional position, this position does not have heat exchange section at its downstream position, and the water that dries that is being produced by heat exchanger 60c in drying operation in this position can not fallen on the room heat exchanger that is used as heater, comprise by a little line shown in 68, be positioned at the position below the room heat exchanger 60b, and comprise position shown in a little line 68a, that be positioned at the air downstream of room heat exchanger 60a.In addition, room heat exchanger 60d not necessarily must be positioned at room heat exchanger 60b above, and can be positioned at optional position, directly added at this position air stream 15, and the water that dries can not fall in the operation of drying, comprise shown in two dot dot dash 69, in position above the room heat exchanger 60a and position shown in two dot dot dash 69a, that be positioned at the upstream of room heat exchanger 60b.

In addition, in Figure 11, though room heat exchanger 60c and room heat exchanger 60d are set at the inlet high-temperature gas area side and the outlet sub-cooled area side of cryogen flow respectively in heating operation, this is not a kind of qualification, but wherein any one can only be set.In the case, can obtain these effects by the corresponding operation of room heat exchanger 60c or 60d.

More specifically, though for room heat exchanger 51a and the 51b among Fig. 9 is provided with two system's refrigerant pipelines, perhaps be room heat exchanger 60a, 60b and 60c is provided with two system's refrigerant pipelines and be provided with single system's refrigerant pipeline for room heat exchanger 60d, this should not become a kind of qualification, and, according to simplicity of refrigerant flow, structure or the like, each among room heat exchanger 51a and 51b or 60a, 60b, 60c and the 60d both can be that individual system also can be a multisystem.For example, when the amount of the refrigerant that flows through is big, preferably adopt the multisystem refrigerant pipeline, with the 51a and the 51b that reduce Fig. 9 or wherein be mixed with 60a, the 60b of Figure 11 of gaseous flow and the pressure drop among the 60c in the heat exchanger.In addition, in heating operation, almost produced therein among the heat exchanger 60d of Figure 11 of liquid stream mode, preferably adopted the single system refrigerant pipeline, increasing the flow velocity in the pipe, thereby increased heat transfer efficiency.When refrigerant flow hour, the structure of pipeline can obtain simplifying further, and can not produce the problem of the pressure loss, and at the 51a of Fig. 9 or adopt the problem that also can not produce the decline of lower efficient under the situation of 60a of single system refrigerant pipeline (not shown) Figure 11; Under the situation of the 51a of Fig. 9, the drying program at upstream side (not shown) refrigerant is lower in cooling down operation in the room heat exchanger.In addition, when refrigerant flow hour, (60a of the 51a of Fig. 9 and 51b or Figure 11,60b, 60c and 60d) can adopt single system refrigerant pipeline (not shown) for all room heat exchangers, simplifying pipeline configuration, and can not produce the problem of decrease in efficiency.

In addition, in the room air conditioner as minitype air conditioner equipment, because the structure of room heat exchanger is restricted and almost is determined, and the free degree of pipeline configuration is very little, also needs to consider these.Below, under these circumstances, will this concrete example be described in conjunction with the embodiment that wherein adopts such as the Figure 11 in two line pipe roads.

Figure 12 is the side view of room heat exchanger 70, and the progression that two line pipe roads and pipeline are wherein arranged is nine.The example of structure that has also shown room heat exchanger 70 pipeline on every side.In Figure 12, by symbol zero expression is to pass the thermal conductive pipe 73 of radiator shutter and what represented by dotted line and solid line is connecting pipe.Label 7 and 8 as Fig. 1 and shown in Figure 11, is represented flow controller and two-way valve respectively.In addition, by dividing radiator shutter 71 by line 72, room heat exchanger 70 is divided into two L shaped heat exchanger 70a and 70b.Thermal conductive pipe 73a and 73b obtain suitable setting, and being divided into a single system cryogen flow, and other heat pipe obtains suitable setting, have the dual system cryogen flow of flow controller 7 and two-way valve 8 therebetween to form.

By said structure, in cooling, add gentleness and dry in the operation, make refrigerant mobile along the direction shown in solid arrow, dotted arrow and some dash-dot arrows respectively.Therefore, though all heat pipes all become low pressure evaporator in cooling down operation, because all heat pipes except that 73a and 73b all are used to the binary channels cryogen flow, pressure drop is very little and can not throw into question.In addition, in the operation of heating, owing to cause and air stream 15 the convection current that flow to thermal conductive pipe 73e and 73f respectively from thermal conductive pipe 73c and 73d at the high-temperature gas refrigerant of the entrance side of room heat exchanger 70, realized high efficiency heat exchange state in the downstream.In addition, owing to have the air stream 15 of lower temperature and be to carry out at thermal conductive pipe 73a that is positioned at outlet side and 73b in the heat exchange of the air of upstream side, and cryogen flow be in a single system to increase flow velocity and to increase heat transfer efficiency, can carry out sub-cooled completely.In the operation of drying, for air stream 15, room heat exchanger 70b becomes cooler/moisture separator (being evaporimeter) at the air upstream side and room heat exchanger 70a and becomes heater (being condenser) in the air downstream so that air stream 15 is cooled off/dries and subsequently it heated.In the case, because becoming the heat exchanger 70a of high temperature is cut apart by being defined by line 72 with the heat exchanger 70b that becomes low temperature, each heat exchanger does not directly disturb with another, so does not have thermal loss, and can carry out the high efficiency operation of drying.In addition, the room heat exchanger 70a that is used as heater be positioned at the room heat exchanger 70b that is used as cooler/moisture separator above, thereby the defluent water that dries can not be heated or evaporation again.

In addition, Figure 13 is that wherein two row heat pipes are configured to nine grades of embodiment of room heat exchanger shown in Figure 12 and revise example.Compare with the embodiment shown in Figure 12, in order in heating operation, to carry out sub-cooled at outlet side, can make heat pipe 74a and the 74b that refrigerant flows in single system upwards moved one-level, and they obtain suitable setting, thus make stream wherein have the inlet heat pipe of high-temperature gas refrigerant to have to be used for air stream 15, be set at the heat pipe 74c and the heat pipe 74d in the downstream of the upstream side of wind and air respectively.This room heat exchanger by the line of representing with label 96 separately.In this pipeline configuration, though the convection current that the heat pipe 74c in heating operation in the high-temperature gas district and heat pipe 74e and 74f in its wind downstream do not cause air stream 15, in the operation of drying, after having carried out cooling and having dried, the height h of the heat exchange section of heating usefulness 2Height h than Figure 12 1Long, its result can obtain the bigger amount of drying.

Figure 14 has shown that another of room heat exchanger that two row heat pipes wherein are configured to Figure 12 of nine grades revise embodiment.In heating operation, form a single system and carry out being configured to two row in the level that supercooled heat pipe 75a and 75b going up most, and wherein stream there are two input heat pipes of high-temperature gas medium to be provided in the heat pipe 75c and the 75d of wind upstream side with outlet side at refrigerant.One room heat exchanger 88 is by line separated into two parts 88a and the 88b shown in the label 89.In this pipeline configuration, though input heat pipe 75c in heating operation in the high-temperature gas zone and 75d and heat pipe 75b, 75e, 75f and the 75g air downstream, that have lower temperature that are provided at them do not cause the convection current of air stream 15, but in the operation of drying, the height h of the thermal conduction portions that after cooling off and drying, is used for heating again 3Can be than the length in the embodiment of Figure 13, and consequently can obtain the bigger amount of drying.

Figure 15 is the side view of an embodiment of room heat exchanger 80, and wherein two row heat pipes are configured to ten grades.It has also shown the pipeline configuration around the room heat exchanger 80.As in the embodiment shown in fig. 12, by symbol zero expression is a plurality of heat pipes that pass radiator shutter.What represented by dotted line and solid line is connecting pipe.Label 7 and 8 is represented a flow controller and a two-way valve respectively.In addition, room heat exchanger 80 by cutting apart radiator shutter 81 in the position shown in cut-off rule 82, is divided into two L shaped heat exchanger 80a and 80b.Heat pipe 83a and 83b are configured to the single system cryogen flow, and other heat pipe is configured to have the dual system cryogen flow of flow controller and two-way valve 8 therebetween.In addition, L shaped heat exchanger 80b is shown as has dual system refrigerant pipeline structure, and this structure comprises by the system shown in the arrow 84 with by the passage shown in the arrow 85 between I branch and J branch.But because the number (being two in the case) of the heat pipe of the pipeline shown in the label 84 is less than by the pipeline shown in the label 85, between the ducted heat pipe 83c and some J of the passage shown in the label 84, be provided with one and stop pipe 86, so that the flow resistance of cryogen flow becomes similar.

By above-mentioned structure, in each of operating is being dried in cooling, heating, refrigerant is flowed respectively along the direction shown in solid line arrow, dotted arrow and some dash-dot arrows.Therefore, effective and no problem ground can resembling in the embodiment of Figure 12, carry out low pressure loss flow of refrigerant condition in the cooling down operation, by inlet high-temperature gas flow of refrigerant and with the convection current of air stream and in heating operation in the abundant supercooled heat exchange condition of the single cryogen flow in export department office and the operation of drying to the cooling of air stream 15/dry and heat effect again.

In this regard, resistance tube 86 can be set at by the some I of the pipeline shown in the label 84 and any position between the J.In addition, in the multisystem refrigerant pipeline, can it be set, thereby the flow resistance in each flow duct is equated in the low place of flow resistance.For example, in the embodiment of Fig. 9 or 11,, in the pipeline that flow resistance is little resistance tube is set therein,, thereby makes the state current downflow of refrigerant in abundant balance so that each ducted flow resistance is equal to the multisystem refrigerant pipeline.

Figure 16 has shown that of room heat exchanger that two row heat pipes wherein are configured to Figure 15 of ten grades revises embodiment.In heating operation, in order to carry out sub-cooled at outlet side, be provided with four heat pipe 87a, 87b and 87i and 87e, so that cryogen flow can be engaged in the single system, and two input heat pipes being flowed into of high-temperature gas refrigerant all are configured to the heat pipe 87c and the 87d of air upstream side.They are cut apart similarly by the line of label 97 expressions.In this pipeline configuration, though input heat pipe 87c in heating operation in high-temperature area and 87d and in their the heat pipe 87e in air downstream and 87f, 87g and the 87h convection current that do not cause air stream 15, in cooling down operation, the height h of the heat exchange section that after cooling off and drying, is used for heating again 5H than Figure 15 4Long, its result can obtain the bigger amount of drying.In addition, the cryogen flow between a K and L is in the dual system, but the length of corresponding heat pipe is constant, thereby makes and resistance tube 86 is set need not resembling in Figure 15.

In this regard, be shown with among the embodiment Figure 12,13,14 and 16, the number of heat pipe that is used as heater is more than the number of the heat pipe that is used as cooler/moisture separator.Its reason is that in conjunction with Fig. 3,4,6 and 8 described embodiment, this is effective for hanging down heating operation.Thereby because in the operation of drying, cooling/dehumidification ability can be lowered and the ability of heater can be enhanced, low heating operation becomes and carries out easily.

Here, though at Figure 12 to the heat exchanger shown in Figure 16, two two heat exchangers that separate all are arranged in the dual system flow of refrigerant pipeline, this also is applicable to the pipeline configuration of such air-conditioning equipment, wherein resemble described in the embodiment of Figure 11 adopted relatively large refrigerant.When refrigerant flow hour, heat exchanger (for example 70a among Figure 12 and the 80a among Figure 15) can be arranged in the single system refrigerant pipeline.In addition, when refrigerant flow hour, also the heat exchanger (for example 70b among Figure 12 and the 80b among Figure 15) that is used as the evaporimeter in downstream in cooling down operation can be arranged in the single system refrigerant pipeline.

As an example, will an embodiment be described in conjunction with Figure 17, it is corresponding with the embodiment of Figure 12 and wherein cryogen flow is less.Here, Figure 17 has shown an embodiment, and wherein the heat exchanger 70a shown in Figure 12 is set in the single system refrigerant pipeline.In Figure 17, label 98 expression room heat exchangers, this room heat exchanger comprise one be divided into two parts by cut-off rule 72 and in cooling down operation, become the downstream evaporimeter heat exchanger 98a with one in cooling down operation, become the evaporimeter of upstream side and wherein refrigerant pipeline be heat exchanger 98b (identical) in dual system with 70b shown in Figure 12.In Figure 17, represent identical parts with label identical among Figure 12.

In above-mentioned structure, in the operation of cooling off, heat and dry, refrigeration filling is flowed respectively along the direction shown in solid arrow, dotted arrow and some dash-dot arrows.In cooling down operation, though room heat exchanger 98a and 98b become low pressure evaporator,, be arranged in evaporimeter 98a upstream side, that wherein degree of drying is lower because cryogen flow is less, although refrigerant pipeline is in single system, the pressure loss is less.On the contrary and since with embodiment shown in Figure 12 in to compare cryogen flow speed higher, it is big that ducted thermal conductivity becomes.In addition, though evaporimeter 98b has bigger degree of drying, because cryogen flow is passed through in two passages, the speed alter of cryogen flow is sufficiently low, makes that pressure drop can be very little.

In addition, in heating operation, in room heat exchanger 98, though cryogen flow becomes slow owing to pressure is high and gaseous refrigerant has less specific volume, because the high-temperature gas cryogen flow is entered earlier the cryogen flow institute condensation of dual system room heat exchanger 98b and is entered subsequently among the single system room heat exchanger 98a, so do not produce the problematic pressure loss.Therefore, when amount of refrigerant hour, in the embodiment of Figure 17, all without any problem, and because the coolant channel of room heat exchanger 98a is that structure is simplified in a single system on efficient for cooling down operation and heating operation.In this regard, in cooling down operation and heating operation and the operation of drying, similar among the state of the heat exchange between room heat exchanger 98 and the air stream and the embodiment of Figure 12.

Here, Figure 12 to the embodiment shown in Figure 16 by 89 among for example cut-off rule shown in Figure 12 72 or Figure 14, the room heat exchanger is divided into two parts fully, and the heat conduction between this heat exchanger that is divided into two is completely severed.This makes and can cool off fully/dry and heat in the operation of drying.But then, produce heat exchanger assembling complicated problems.For addressing this problem, the radiator shutter before the heat pipe is preferably assembled according to Figure 18 and mode shown in Figure 19.

As shown in figure 18 radiator shutter is installed by suitable figure, so that it has the branch slot 92 corresponding with the cut-off rule 72 shown in Figure 12.Because such structure, make heat insulation how much become relatively poor though compare seam 92 with cut-off rule 72 shown in Figure 12, but the limit 91a of radiator shutter 91 and the heat conduction between the 91b of limit can be cut off, and because the limit 91a and the limit 91b of radiator shutter 91 link together, it is easy that the assembling of heat exchanger becomes.

In addition, radiator shutter 93 has suitable structure, thereby is provided with branch slot 94 in the part corresponding with cut-off rule shown in Figure 14 89.In the case, with the same in the embodiment shown in Figure 18, by seam 94, the limit 93a of radiator shutter 94 and the heat conduction between the 93b are cut off, and because limit 93a and 93b link together, the assembling of heat exchanger has become easily.

In addition, in the aforementioned embodiment, the person is according to adopting the single refrigerant such as HCFC22 (abbreviation of hydrochlorofluorocarbon 22) to describe.But recently,, carrying out increasing research aspect the sub of seeking HCFC22 for the consideration of ozone layer decay and global warming.In addition, seeking to be not only single refrigerant but aspect the sub of mixed cooling medium, studying.Wherein, for single refrigerant, though difference is arranged on force value, refrigerant cycle and its characteristic and HCFC22's is similar.And, for mixed cooling medium, also can be applicable to pipeline configuration of EGR that Fig. 1 describes to the embodiment shown in Figure 19, indoor unit structure, method of controlling operation thereof, room heat exchanger or the like, to obtain similar effects.

In addition, adopt mixed cooling medium, by usually adopting as the pipeline configuration of the room heat exchanger that Figure 11 is extremely shown in Figure 17, also can obtain with single refrigerant the following effect that can not obtain.

Figure 21 has shown when adopting single and mixed cooling medium the typical temperature-entropy curve about refrigerant cycles.In this temperature-entropy curve, when cooling down operation is when adopting example pipeline configuration as shown in Figure 11 to carry out, in being used as the room heat exchanger of evaporimeter, because the evaporating temperature of cryogen flow, because the pressure drop under the situation of single refrigerant, and promptly the some Ta from Figure 21 is to a Pa reduction from the porch towards the exit, and room heat exchanger 60a becomes the evaporimeter of high temperature side and the evaporimeter that room heat exchanger 60b becomes low temperature side, and cryogen flow and air stream 15 do not form convection current.In contrast to this, under the situation of mixed cooling medium, general in evaporation process mixed cooling medium under gas phase and the mixing ratio under liquid phase change, and according to this variation, evaporating temperature is promptly increased to putting P from a T as shown from inlet to its outlet of room heat exchanger.Its result, in the embodiment shown in fig. 11, because the evaporating temperature of room heat exchanger 60a becomes and is lower than the evaporating temperature of room heat exchanger 60b, cryogen flow and air stream 15 have formed convection current, thereby have produced than the more effective heat exchange state of single refrigerant.

In this regard, in heating operation, as representing respectively through R to S institute through Ra to Sa and from a Q from Figure 21 mid point Qa, owing to all reduce towards its outlet from the inlet of room heat exchanger at the refrigerant temperature of single medium of condensation side and blending agent, the temperature relation between cryogen flow and the air stream under the situation of single refrigerant be identical under the situation at mixed cooling medium.

Though above description is to carry out according to such structure, promptly in this structure, be configured to series connection mutually as the room heat exchanger 6a that be divided into two, that be used for air stream 15 of Fig. 1 and 6b, but this should not become a kind of restriction, and be connected in parallel to each other by the heat exchanger that will be divided into two, be used for air stream is provided with (upper and lower), also can obtain similar function and effect in the operation of drying.Figure 22 has shown refrigerant cycles and the control system that comprises in such an embodiment.Label 110a and 110b represent to be used for 15, that be divided into two and be connected in parallel to each other (upper and lower) the room heat exchanger that is provided with of air stream in Figure 22.Identical and represent among other part and Fig. 1 with identical label.Compressor 1 can carry out ability control, and outdoor fan 10 and room fan 12 can carry out ability control and can control the blowing amount.

Here, though shown room fan 12 makes room heat exchanger 110a and 110b cause the PARALLEL FLOW of air, also can suitably constitute the room heat exchanger, to make it to bend to the form of symbol "<", so that room fan 12 to be set in this wise, flow to room heat exchanger 110a and 110b in parallel abreast even get air.By such structure, wherein stream has the pipeline of air just to form easily.

In the EGR of Figure 22, the same with the EGR of Fig. 1, in cooling down operation, by closing two-way valve 5 and opening two-way valve 8, refrigerant just circulates shown in the solid line arrow, the room is cooled off with the room heat exchanger 6a and the 6b that are used as evaporimeter by the outdoor heat converter 3 that is used as condenser.In heating operation, by switching cross valve 2, closing two-way valve 5 and open two-way valve 8, refrigerant is circulated, to heat with the 3 pairs of rooms of outdoor heat converter that are used as evaporimeter shown in dotted arrow by room heat exchanger 6a that is used as condenser and 6b.

In addition, in the operation of drying, by resembling in cooling down operation, switch cross valve 2, open two-way valve 5 and close two-way valve 8, make refrigerant shown in some dash-dot arrows, successively through cross valve 2, outdoor heat converter 3, two-way valve 5, room heat exchanger 110a, the flow controller 7 that dries, room heat exchanger 110b, cross valve 2, gatherer 9 and compressor 1, circulate, and make outdoor heat converter 3 become the condenser of upstream side, make room heat exchanger 110a become the condenser in downstream, and make room heat exchanger 6b become evaporimeter.And, when room fan 12 makes that space air flows as shown in arrow 15ly, the room heat exchanger 110b that portion of air stream is used as evaporimeter cools off/dries, and the flow through room heat exchanger 110a that is used as condenser and heater and being blown in the room of remaining air.In the case, by the ability of control compressor 1 and the blowing ability of outdoor fan 10, the ability of adjustable expander 110b and heater 110a, and finally can regulate the amount of drying and air blowing temperature according to concrete purposes.

Therefore, in the operation of drying, room heat exchanger 110a that is divided into two therein, be used for air stream 15 and 110b are by under the situation about being provided with associated with each other (upper and lower), similar with the room heat exchanger 6a that wherein is divided into two, be used for air stream 15 and 6b by the situation of Fig. 1 of (the preceding and back) setting of connect each other, can carry out various operations.Therefore, can carry out the identical operations method with Fig. 2 to Fig. 4, and obtain similar effects.Particularly, can carry out any operation of drying, comprise happiness the dry operation of operation, " good night "/" good morning ", mould/tick prevent to dry operation and laundry operations according to various uses.Can also carry out drying operation and the operation of low air flow amount and the operation of upper air current amount of suitably dividing according to these, and according to room temperature hang down cooling, gentleness such as low is hanged down heating operation.

In addition, in aforesaid upper air current amount was dried operation, because compressor is to move under high ability, it is big that input becomes.Shown a kind of embodiment that can address this problem among Figure 23.Embodiment at Fig. 5 compares, and Figure 23 is the schematic diagram that shows an indoor unit, and heat exchanger is divided into upper and lower two parts in this indoor unit.Label 110a, 110b and 12 be respectively with at the identical parts described in the EGR of Figure 22, and room heat exchanger, room heat exchanger and room fan are down gone up in expression respectively.Represent identical parts with label identical among Fig. 5.

In above-mentioned structure, in the operation of drying, room heat exchanger 110b becomes an evaporimeter, and room heat exchanger 110a becomes a heater.By operation room fan 12 space air is flowed shown in arrow 36 and 37, air stream 36 is by air inlet fence 31, and cooled off/dry by evaporimeter 110b part ground, and, and after through room fan 12, be blown along the direction shown in the arrow 37 simultaneously by the heating of heater 110a part ground.In addition, the condensed water of evaporimeter 110a generation is received and is discharged to outside the room subsequently by plate 33.

In this regard, adopt the various methods of operating of the indoor unit shown in Figure 23, with identical under the situation of aforesaid chamber unit 5.The upper air current amount method of operating of drying becomes as shown in Figure 6 flow chart, to obtain identical effect among the embodiment with Fig. 5.

In addition, under the situation of Figure 22, obviously also with similar under the situation of Fig. 1, the embodiment that can adopt Fig. 7 is to obtain similar effects.More specifically, be configured to structure by the part 40 that will in Figure 22, be surrounded as Fig. 7 by two dot dot dash, and with the heat dissipation capacity at as shown in Figure 8 low heating drying method conditioning chamber outer heat-exchanger 3 places, the low heating that can the have more heating property operation of drying by the EGR of Figure 22.

In this regard, though be to carry out under the situation of the EGR of supposition shown in Fig. 1,7 or 22 to the description of method of operating in the operation of drying as shown in Fig. 2,3,4,6 and 8, this is not a kind of restriction.In air-conditioning equipment with EGR that room heat exchanger wherein is divided into two, be provided with the flow controller that dries betwixt, and in the operation of drying, the upper and lower side of the cryogen flow of the room heat exchanger that is divided into two is used as heater and cooler/moisture separator respectively, as mentioned above, usually before can using wherein the room heat exchanger and being set at and rear side make again air stream flow through successively the situation of these room heat exchangers and wherein the room heat exchanger be provided with up and down so that air stream flows through the situation of these room heat exchangers that are provided with being connected in parallel to each other, with the realization similar effects.

In addition, though the EGR under the operational circumstances that dries to embodiment shown in Figure 22 is described, with the same under the EGR situation of Fig. 1, for cooling and heating operation, need to guarantee the cycle efficieny of room heat exchanger 110a and 110b, thereby effectively move.Below this respect will be described.At first, in the embodiment shown in Figure 22, be provided with the room heat exchanger 110a and the 110b that are divided into two.Further, in cooling and heating operation, owing to their through two-way valve 8 connection that is one another in series, especially in cooling down operation, room heat exchanger 110a and 110b become the evaporimeter that wherein specific volume is big and volume flow is big, and its result, the pressure loss of room heat exchanger strengthens, thereby has reduced cycle efficieny.

Shown an embodiment that can address this problem among Figure 24.This embodiment is corresponding with the heat exchange section of the room side part of being surrounded by a little line in the embodiment shown in Figure 22.In Figure 24, label 100a and 100b represent the room heat exchanger that is divided into two respectively.In addition, room heat exchanger 100a is divided into dual system refrigerant pipeline 101 and 102 at a P, and these pipelines are bonded into the single system refrigerant pipeline again at a Q.Similarly, room heat exchanger 100b is divided into dual system refrigerant pipeline 103 and 104 at a R, and these pipelines are bonded into the single system refrigerant pipeline again at a S.And, represent identical part with label identical among Figure 22.

In said apparatus, in cooling and heating operation, by opening two-way valve 8, refrigerant enters in the dual system at room heat exchanger 100a and 100b respectively.Therefore, the refrigerant flow in each system has been reduced half and has been reduced in the pressure drop of the cryogen flow of room heat exchanger 100a and 100b.As a result, prevented the reduction of efficient.

In this regard, though in the embodiment shown in Figure 24, room heat exchanger 100a and 100b are divided into the dual system refrigerant pipeline, and this does not become a kind of restriction, and they can be divided into a plurality of systems.In the case, the cryogen flow pressure drop at room heat exchanger 100a and 100b place also can be reduced and also can stop the reduction of efficient.Yet when cryogen flow was excessively shunted, though the pressure drop of cryogen flow reduces, thermal conductivity was excessively reduced, and comprised that the whole efficiency of the cooling capacity or the coefficient of performance has been lowered.Thereby, an optimizer system number is arranged, it is by the decision of the internal diameter of refrigerant pipeline.

In addition, in heating operation, in order to increase the efficient that comprises the heating efficiency and the coefficient of performance, system need suitably be set, thus with the room heat exchanger that becomes condenser in cryogen flow export corresponding heat exchanger and partly produce sufficient sub-cooled (sub-cooling).In Figure 25, shown an embodiment that can realize this point.In Figure 25, label 100c represents a room heat exchanger, and it comprises binary channels refrigerant pipeline 106 and 107, and these pipelines connect at a T and single system refrigerant pipeline 105 and are incorporated in the downstream that is positioned at cryogen flow in the heating operation.And, represent identical part with the identical label among Figure 24.Therefore, in the embodiment of Figure 25, Figure 24, wherein refrigerant pipeline is twin-channel room heat exchanger 100a, heat exchanger 100c replaces by the room, a single system refrigerant pipeline combines with the dual system refrigerant pipeline in the latter.

In said structure, in heating operation, refrigeration filling flow through successively room heat exchanger 100b, two-way valve 8 and room heat exchanger 100c.In the case, the high-temperature gas cryogen flow that shown in dotted arrow, enters and air stream 15 carry out heat exchange and therein refrigerant pipeline be 103 and 104 room heat exchanger 100b and wherein refrigerant pipeline be that the dual system of 106 and 107 room heat exchanger 100c obtains sufficient condensation in partly.Subsequently, the liquid refrigerant of this condensation flows in the single system refrigerant pipeline 105 of room heat exchanger 100c, to increase its speed and to become such state, under this state, can carry out sub-cooled completely because ducted thermal conductivity alter is high fully.As a result, set up highly effectively heat exchange condition.

In addition, in cooling down operation, refrigerant is from single system refrigerant pipeline 105 flow through successively dual system refrigerant pipeline 106 and 107, two-way valve 8 and dual system refrigerant pipeline 103 and 104.In the case, in single system refrigerant pipeline 105, it is high like that the pressure loss does not become, because the degree of drying of cryogen flow is low.In single system refrigerant pipeline 5,, the effect that ducted thermal conductivity increases and heat transfer efficiency increases is arranged also in addition because the flowing velocity of cryogen flow becomes big.

More specifically, though room heat exchanger 100a and 100b have the dual system refrigerant pipeline in Figure 24, or room heat exchanger 100b has the dual system refrigerant pipeline in Figure 25, and room heat exchanger 100c has the composite channel that comprises single system refrigerant pipeline and dual system refrigerant pipeline, but these should not become restriction.On the contrary, according to the simple degree of refrigerant flow and device, room heat exchanger 100a, 100b and 100c can be list or multisystem.For example, when amount of refrigerant was big, the room heat exchanger 100a of Figure 24 and the 100c of 100b or Figure 25 and 100b (wherein being mixed with gaseous flow) preferably had a plurality of systems refrigerant pipeline (the room heat exchanger 100c of Figure 25 also can have the complex of single system or a plurality of passages).When amount of refrigerant hour, if the 100c of the room heat exchanger 100a of Figure 24 or Figure 25 (wherein in cooling down operation cryogen flow be in the upstream and its degree of drying less) have a single system refrigerant pipeline (not shown), then wherein less and decline efficient of the pressure loss produces any problem hardly.And pipeline configuration becomes simple.When amount of refrigerant more hour, if all room heat exchangers (100a of Figure 24 and 100b or 100c and 100d) all have single system refrigerant pipeline (not shown), then the decline of efficient does not produce any problem and pipeline configuration becomes simple further.

About the type of the cryogen flow in the refrigerant cycles of Figure 22, with the same in the embodiment in figure 1.The control method of above-mentioned EGR, indoor unit structure and operation and pipeline configuration of room heat exchanger or the like, all can be used to single refrigerant or various mixed cooling medium, with as the conspicuous similar effects that obtains such as HCFC22.

In addition, though for the control method of the ability of compressor, room fan and outdoor fan, more than the revolution control that utilizes common phase inverter or DC motor is described, also can adopt various other methods.For example, for compressor, can adopt a kind of method of ability being carried out machinery control; For the blowing fan, can adopt the method for the tap of switching an AC motor, a kind of method or a kind of method that increases flow resistance of compressed air piping.In addition, in general, at present the upper air current amount of used room fan is not more than air mass flow in cooling and heating operation in the operation of drying.

In addition, in the embodiment shown in Fig. 1,9,11,12,13,14,15,16,17,22,24 and 25, as mentioned above, main flow controller 4 or dry that flow controller is not limited to fix, such as flow controller capillaceous, and they can be the variable restrictor devices that drives expansion valve such as expansion valve or motor.In the case, can carry out further accurately control.Especially, when adopting the motor that full open position wherein can occur to drive expansion valve, can be without two-way valve 5 or two-way valve 8.For example, shown in the part that dotted line surrounded among Fig. 1 and 22, part of forming by the flow controller 4 and the two-way valve 5 of parallel connection 45 and the part of forming by the flow controller 7 and the two-way valve 8 of parallel connection 46, all can be driven expansion valve by a motor as shown in figure 20 and replace, in this expansion valve, can produce the state of opening fully.

In addition, though above to wherein cooling off, heat and the refrigerant cycles of the three kinds of operations of operation of drying being described, this should not become a kind of restriction, and method of operating described above and heat converter structure can be used for other refrigerant cycles.For example, in the embodiment shown in Fig. 1 and 22, can remove cross valve 2.Room heat exchanger 6b or 110b, gatherer 9, compressor 1 and outdoor heat converter 3 by mutual series connection, a kind of refrigerant cycles be can produce, the cooling down operation of the cryogen flow shown in the solid line arrow and the operation of drying of the cryogen flow shown in some dash-dot arrows wherein can be carried out.In the operation of drying of this refrigerant cycles, by the method for operating shown in Fig. 2,3 and 4, in as the indoor unit structure of Fig. 5 or 23 as shown in Figure 6 method of operating or as shown in Figure 8 method of operating in the embodiment shown in fig. 7, can obtain similar effects.

In addition, in the refrigerating circulating apparatus of Fig. 1 or 22, gatherer is optional.According to the type of compressor, the kind and the control method of flow controller, can not have to constitute refrigerant cycles under the situation of gatherer.

Below, will be in conjunction with Figure 26,27,28 and 29 and mainly in conjunction with the operation of drying, an embodiment of further concrete method of operating is described.

Figure 26 is a schematic diagram, has shown the Temperature Detector (generally comprising a thermistor) of a circulatory system, each several part and a humidity detector (generally comprise a moisture detector but humidity can come out from the temperature computation that detects) in some cases.One dry the operation in, the refrigerator that comes out from compressor 601, through cross valve 602, outdoor heat converter 603, bypass two-way valve 606 (generally comprising a magnetic valve), enter the room heat exchanger 608 that is used as heater, and flow controller 619 decompressions of being dried, process is used as the room heat exchanger 609 of evaporimeter, and gets back to compressor 601.In addition, have the outdoor temperature detector 615 that is used to detect outdoor temperature at this outdoor unit, and indoor unit has moisture detector 616 that is used for detected temperatures and the room air blowing Temperature Detector 618 that is used to detect the room suction temperature detector 617 of room suction temperature and be used to detect room air blowing temperature.These Temperature Detectors link to each other with the control section (not shown) with moisture detector.

Now in conjunction with Figure 27 and 28 embodiment that describe according to control method of the present invention.

Figure 27 has shown the temperature that detected according to outdoor temperature detector 615 control method to outdoor fan 611.When outdoor temperature reduces, because the heat that outdoor heat converter 603 is distributed increases and the caloric value of the room heat exchanger 608 in the operation of drying reduces, when outdoor temperature reduced, the revolution of outdoor fan 611 was lowered to stop the reduction of room suction temperature.In addition, by electrical equipment and operating room external fan 611 are set at outdoor unit, have in the outdoor unit of appropriate configuration in rising for the temperature of this electrical equipment of stoping outdoor unit, because rising the temperature of this electrical equipment in the outdoor unit, the rising of outdoor temperature increases, the revolution of outdoor fan 611 is increased, and rises to reduce this temperature.

Store as calculating agenda by the control method of definite outdoor temperature and outdoor fan 611 or with it, utilize the model or the accounting equation of storage in advance, the outdoor temperature that Temperature Detector 615 detects outside the used chamber is controlled outdoor fan 611.In addition, in the case, not only the revolution of outdoor fan 611 is changed by outdoor temperature, and has carried out a kind of on-off intermitten service, and by logical and disconnected time ratio is carried out variable control, can obtain identical effect.

According to this control method, even outdoor temperature reduces, the air blowing temperature in room can not reduce yet.Not only improved level of comfort, and when outdoor temperature rises, by increasing the revolution of outdoor fan 611, can rise to the temperature of the electrical equipment that is arranged on the outdoor unit side and control, to guarantee the reliability of this electrical equipment.

Figure 28 has shown the method for the humidity control compressor 601 that detects with moisture detector 616.When room humidity was high, the revolution of compressor 601 was increased, with the refrigerant circulation quantity in the increase refrigerant cycles, thus the operation of the amount of drying greatly, with rapid reduction room humidity.In addition, when room humidity was low, the revolution of compressor 601 was lowered, to carry out high efficiency operation.Be stored in the control section as a processing equation by the control method of definite room humidity and compressor 601 or with it, can control the revolution of compressor 601 according to the room humidity that room moisture detector 616 is detected.

As mentioned above, by coming the method for operation of control room external fan 611 and the revolution of compressor 601 according to outdoor temperature and room temperature, the operation of can carrying out happiness and degree of spending effectively dries.

According to this control method, when room humidity is high,, make the revolution of compressor 601 reach maximum for example in when beginning operation, carrying out the operation of drying of big dehumidification ability, thereby rapidly room humidity is reduced to desirable humidity.When room humidity was lowered to desirable humidity, the revolution of this compressor was lowered, effectively to move in the lower operation of drying.By these control methods, can carry out well-formedness higher, the highly effectively operation of drying.

To describe according to another control method of the present invention in conjunction with Figure 29 now.

This is that basis is by the temperature of room air blowing Temperature Detector 618 detections and the method for coming control room external fan 611 and compressor 601 and revolution by the temperature difference between the temperature of room suction temperature detector 617 detections.When room air blowing temperature was lower than the room suction temperature, the revolution of outdoor fan 611 was lowered, and with the heat dissipation capacity of reduction outdoor unit side, thereby improved room air blowing temperature.In addition, by changing (increase or reduce) compressor 601 revolutions, can change room air blowing temperature as required.The increase of the revolution of compressor 601 and reducing can change according to the size ratio of room heat exchanger 609, reheat heat exchanger 608 and the outdoor heat converter 603 of refrigerant cycles.(control method of the revolution of compressor 601 becomes solid line or little by little line.)

In addition, when the difference of the temperature of setting alternatively according to room temperature and (room user's temperature desired) is determined temperature difference between room air blowing temperature and the room suction temperature, for example, when room temperature is higher than the temperature of this optional setting, carry out such control, promptly feasible (room air blowing temperature)-(room suction temperature)≤0 is so that outdoor fan 611 has higher revolution and compressor 601 is moved under suitable control.When room temperature is lower than this optional design temperature, carry out such control, promptly feasible (room air blowing temperature)-(room suction temperature)>0 is so that outdoor fan 611 is moving under the lower revolution and compressor 601 is moved under suitable control.

In these cases, not only control room external fan 611 moves continuously, and carries out the on-off intermitten service, and by determining the on-off time ratio according to the temperature difference between room air blowing temperature and the room suction temperature, can obtain further effect.The method of operation of this temperature difference between room air blowing temperature and the room suction temperature and outdoor fan 611 and compressor 601 is determined in advance or handles, and is stored in the control section.

By these control methods, can improve the comfortableness in the operation of drying.
