The specific embodiment
At first, explain before the concrete structure,, notion of the present invention is described based on Fig. 1.Fig. 1 is the figure of principle that is used to explain the control method of air-conditioning system of the present invention.Air-conditioning system of the present invention; As after state shown in Figure 3; Be to possess the thermophore runner pipe 6 that constitutes the thermophore circulation path that thermophore flows through and be heated and the radiant panel 1 of the plate main body 7 of this heat radiation is arranged at by the ceiling of the R of air conditioning chamber, utilize the heat radiation of radiant panel 1, carry out the air-conditioning system of refrigeration and heating from the thermophore that in this thermophore runner pipe 6, flows through; It is characterized in that; It is that surface temperature control through the plate main body 7 that will constitute radiant panel 1 whole year becomes set point of temperature (for example 23 ℃), and, be different from surface temperature control and the air-conditioning system of independent control indoor temperature (also having indoor humidity) of plate main body 7.Being controlled to room temperature in summer is 28 ℃, is 20 ℃ in the winter time.As the control method of indoor temperature, control room temperature with the ratio of the heat exchange of the ventilation air quantity that imports outer gas.More specifically method after detail in the embodiment stated.
At this, in by the R of air conditioning chamber, have people H (below, be also referred to as an inhabitation people H sometimes) people, imagination is kept normal condition.Also have, when refrigeration, make 20 ℃ cold water flow through radiant panel 1, when heating, make 25 ℃ flow of hot water overshoot plate 1.
At this, " surface temperature of plate main body 7 " can in the both side surface of plate main body 7 towards by the surface of the indoor side of the R of air conditioning chamber and towards any surface temperature on the surface of a side of end face.Plate main body 7 is used the good material of pyroconductivities, therefore, and the surface temperature of the side in the faced chamber and all can not change towards the surface temperature of a side of end face.Thereby, the surface that the surface temperature testing agency (temperature sensor) of the surface temperature of check-out console main body is arranged at the side in the faced chamber also can, in addition, be arranged at towards the surface of a side of end face and also can.
Secondly, as characteristic of the present invention, be maintained at 23 ℃ through surface temperature with plate main body 7; In when refrigeration, even be under the situation of 28 ℃ (in heating time, indoor temperature is 20 ℃) in indoor temperature; Inhabitation people H also feels comfort, describes for above-mentioned reason.
Usually, the surface temperature is 31 ℃, and body surface area is 1.6m 2In addition, people's caloric value is made as 45W/m 2Thereby people's caloric value becomes 45 * 1.6=72W.
The radiation from the people when on the other hand, the surface temperature control of plate main body 7 being 23 ℃ absorbs heat qw and obtains through following mathematical expression.
qw＝A1·F·ε·Γ{(T1/100) 4-(T2/100) 4}
Where, A1 = area of the radiating surface, F = geometric count (count shape), ε = emissivity, Γ = Stefan Boltzmann constant = 5.67 × 108W / m 2 K, T1 = radiating surface temperature = 23 +273 = 296 ℃, T2 ='s surface temperature = 31 +273 = 304 ℃.
At this, consider the per unit area of radiant panel, therefore, A1=1m 2In addition,, the geometry counting is made as 0.8, radiance is made as 0.95 for facility.Thereby radiation absorbs heat qw becomes qw=1 * 0.8 * 0.95 * 5.67 * (296/100) 4-(304/100) 4=-37W/m 2H.
On the other hand, come distribute heat through radiation from 50% of people's distribute heat, therefore, 72 * 50 * 10 -2=36W, consistent with the absorption heat of radiant panel.In addition, the performance of radiant panel also comprises the convection current composition, therefore, and can be with about 23 ℃ caloric values that absorb the people of surface temperature of plate main body 7.On the other hand, the people is a heater, and comfort does not receive room temperature influence, and the influence of raying plate surface temperature.Its result is under the situation about 28 ℃ in room temperature, becomes 23 ℃ through the surface temperature control with plate main body 7, makes indoor inhabitation people H obtain comfort.Below, be divided into when refrigeration during with heating and then detailed description.
(under the situation during refrigeration)
Under the normal condition of Fig. 1, room temperature is 28 ℃, and therefore, wall also becomes 28 ℃ or near its value.On the other hand, the human surface temperature of known people H is maintained steady temperature (31 ℃) all the time in the whole year.Under such environmental condition; If the surface temperature of plate main body 7 becomes 23 ℃, the moving of the heat that then carries out causing to the heat radiation of wall from people H, and; Moving of the heat that carries out causing to the heat radiation of radiant panel 1 from people H; Therefore, under 28 ℃ the situation, also obtain comfort even be in room temperature.
More specifically, imagination is not provided with the situation of radiant panel 1 at end face.In this case, wall and end face are 28 ℃, the moving of the heat that carries out causing to the heat radiation of wall and end face from people H.Like this, in the heat radiation under the situation that end face around people H and wall are 28 ℃, the caloric value of people H by heat absorption fully, therefore, not can not get comfort.With respect to this, be provided with under the situation of radiant panel 1, the surface temperature of plate main body 7 is maintained 23 ℃, therefore, absorbs the caloric value of people H fully, obtains comfort.In other words, in the absence of radiant panel, absorb heat corresponding to 31 ℃-28 ℃=3 ℃ from people H; Have under the situation of radiant panel 1; Absorb heat from people H corresponding to 31 ℃-23 ℃=8 ℃, therefore, under situation with radiant panel 1; The caloric value of people H is absorbed fully, obtains comfort.And, the surface temperature of plate main body 7 is maintained set point of temperature (23 ℃), therefore, the sticky feeling of also not following the frequent variations of the surface temperature of plate main body 7 to cause.Like this, the sticky feeling that absorbs caloric value fully and do not follow the frequent variations of the surface temperature of plate main body 7 to cause, thus, inhabitation people H also can obtain comfort under the situation of 28 ℃ of room temperatures.
Also have, taken place from such normal condition to become 23 ℃ through surface temperature control under people's the variation or situation that cooling load changes of number, obtain comfort with the principle identical with above-mentioned normal condition with plate main body 7.
(control during heating)
Under the normal condition of Fig. 1, room temperature is 20 ℃, and therefore, wall also becomes 20 ℃ or near its value.Under such environmental condition, the human surface temperature of people H is 31 ℃, therefore, carries out moving to the heat that the heat radiation of wall causes from people H.On the other hand, the surface temperature of plate main body 7 is 23 ℃, therefore, carries out moving to the heat that the heat radiation of radiant panel 1 causes from people H.At this, imagine the situation that is not provided with radiant panel 1 at end face, then in this case, end face becomes 20 ℃, carries out moving to the thermal-radiating of end face from people H.In this case, the mobile absorption of carrying out causing to the heat radiation of end face from people H is corresponding to the heat of 31-20=11 ℃ the temperature difference.Thereby under such environment, room temperature is under 20 ℃ the situation, and the ratio of caloric value of drawing people H is also excessive, can feel cold.On the other hand, be provided with at ceiling under the situation of radiant panel 1, the mobile absorption of carrying out causing to the heat radiation of radiant panel 1 from people H is corresponding to the heat of 31-23=8 ℃ the temperature difference.Thereby, to compare with the situation that radiant panel 1 is not set at end face, the heat of drawing from people H is little.In other words, correspondingly suppress the heat absorption of caloric value, the part of caloric value is trapped in the surface of people H, and room temperature is under 20 ℃ the situation, also to feel happy warming sense, obtains comfort.And the surface temperature of plate main body 7 maintains set point of temperature (23 ℃), therefore, and the sticky feeling of also not following the frequent variations of the surface temperature of plate main body 7 to cause.Like this, the sticky feeling that a little ground suppresses caloric value and do not follow the frequent variations of the surface temperature of plate main body 7 to cause, thus, inhabitation people H also feels happy warming sense under the situation of 28 ℃ of room temperatures, obtain comfort.
Taken place from such normal condition under people's the variation or situation that heat load changes of number, the surface temperature control of plate main body 7 has been become 23 ℃, thus, obtained comfort with the principle identical with above-mentioned normal condition.
Like this; The principal character of the control method of air-conditioning system of the present invention is, is taken into outer gas, carries out temperature adjustment/damping; Room temperature is controlled to set point of temperature, and (be 28 ℃ summer; Be 20 ℃ winter), and, will be for to people's giving of heat and the surface temperature control of the plate main body of using 7 becomes 23 ℃ in the radiant panel 1.Thus, the sticky feeling that does not have the variation of the surface temperature of plate main body 7 to cause can obtain the refrigeration and heating of the original comfort of radiation air-conditioner.
Also have, when refrigeration, 20 ℃ the cold water that flows into radiant panel 1 is through radiant panel 1, and temperature rises to 23 ℃, flows out from radiant panel 1.When heating, 25 ℃ the hot water that flows into radiant panel 1 is through radiant panel 1, and temperature is reduced to 23 ℃, flows out from radiant panel 1.On the other hand, the surface temperature control of plate main body 7 is 23 ℃, and the surface temperature of people H constant be 31 ℃, therefore, based on being constant to the thermal-radiating amount of heat transfer of radiant panel 1 from people H.If such, then be conceived under the situation of radiant panel 1, heat absorption when refrigeration, therefore when heating heat release, thinks contradiction under the situation at first sight.But, if consider the situation of the heat budget balance that radiant panel 1 is whole, contradiction not then.As a reference, below, its reason narrated.
That is, when refrigeration, room temperature is set at 28 ℃, and therefore, the plate main body 7 that surface temperature is 23 ℃ utilizes heat to transmit heat absorption from 28 ℃ air.Thereby, think that radiant panel 1 absorbs heat that the heat radiation from people H causes and the heat of the summation of the heat that causes from the heat conduction of air, thus, 20 ℃ cold water is through radiant panel 1, and temperature rises to 23 ℃.On the other hand, when heating, room temperature is set at 20 ℃, and therefore, the air that the plate main body that surface temperature is 23 ℃ is 7 pairs 20 ℃ conducts through heat and dispels the heat.Thereby radiant panel 1 is through absorbing heat from the heat radiation of people H, and carry out to air based on heat conducting heat radiation.And the latter's heat is bigger than the former, therefore, as the heat budget balance of radiant panel 1 integral body, dispels the heat, and therefore, thinks that 25 ℃ hot water passes through radiant panel 1, and temperature is reduced to 23 ℃.Thereby when refrigeration, 20 ℃ cold water is through radiant panel 1, and temperature rises to 23 ℃, and when heating, 25 ℃ hot water is through radiant panel 1, and temperature is reduced to not contradiction of 23 ℃ of these situation.

On the other hand, in damping air interchanger 50, carry out following processing.At first, outdoor air utilizes air to import total heat exchanger 53 with pipe arrangement 57.Then, this air in total heat exchanger 53, and utilize room air to import between the air of the interior space of pipe arrangement 55 guiding and carry out total heat exchange.Utilize temperature and the humidity of room air that room air imports pipe arrangement 55 guiding all than low, therefore, become the air that temperature and humidity reduce by high temperature/many wet air of air feed pipe arrangement 57 guiding by the air of air feed pipe arrangement 57 guiding.
Secondly, the air that temperature and humidity have reduced is to sensible heat exchanger 58 guiding, and the air of the damping unit 68 that passed through to constitute by thermophore runner pipe 59 and humidifier between carry out the sensible heat exchange.The air that has passed through damping unit 68 is low temperature and low humidity like the back saidly, therefore, becomes by the air of total heat exchanger 53 guiding and to have only the lower state of temperature under the state of having kept absolute humidity, and guiding damping unit 68.
In damping unit 68, air has been through having supplied with around 7 ℃ the thermophore runner pipe 59 of cold water, and thus, airborne moisture (steam) is at the surface condensation of thermophore runner pipe 59, and is removed.The never illustrated drainpipe of the air of removing is discharged to the outside.The air that has passed through this thermophore runner pipe 59 becomes low temperature and the low air of absolute humidity.
The air that has passed through damping unit 68 in sensible heat exchanger 58, through with sensible heat exchange by the air of total heat exchanger 53 guiding, keep the state of absolute humidity and heated (18 ℃) down, via in pipe arrangement 63 guide chamber below ground.Below ground air is from blowing out to the top below ground in the guide chamber, and receives the influence of the outer gas heat that imports at indoor people's liberated heat or from window etc. etc., and temperature and absolute humidity all rise.Also have, room air is via pipe arrangement 55 guiding total heat exchangers 53, and utilize between the outdoor air of air feed guiding and carry out total heat exchange.Thus, form the state that temperature and humidity all uprise from the air of indoor guiding, and to outdoor discharge.

At this, utilize temperature sensor T2 to keep watch on outer temperature degree, will give to control device 70 from the temperature detection signal of temperature sensor T2.Control device 70 is controlled the aperture of ventilation with air throttle 54 corresponding to detected temperatures.Thus; As shown in Figure 4, utilize room air to import air with the interior space of pipe arrangement 55 guiding, to through the stream 55A of total heat exchanger 53 with do not pass through the stream 55B distribution of total heat exchanger 53 according to the aperture of ventilation with air throttle 54; Mix then, be discharged from pipe arrangement 56 via exhaust.Its result; In total heat exchanger 53, at the outdoor air that utilizes first air feed stream guiding with utilize when carrying out the exchange of sensible heat and latent heat between the air of the interior space of exhaust flow path guiding, can effectively utilize the heat energy that air had of discharging to the outside from the interior space; Temperature or humidity regulation that outdoor air is had are the state of expectation; And, therefore, can reduce the live load of sensible heat exchanger 58 with its guiding sensible heat exchanger 58.Also have, when being not limited to the dehumidifying operation in summer, after during the humidification operation in winter of stating; Too according to outer temperature degree; Control ventilation is with the aperture of air throttle 54, therefore, and when the dehumidifying operation and humidification both when moving; Can access and significantly economize the ability effect, can further reduce the operating cost of air-conditioning equipment.Also have, can also adopt the structure of having omitted this total heat exchanger 53.
In addition, if indoor temperature change generated in case is then utilized temperature sensor T3 that it is detected, and temperature detection signal is given to control device 70.Control device 70 is according to detected temperatures, and the control of control temperature is with the aperture of air throttle 61.Thus; As shown in Figure 4, utilize air that damping unit 68 regulates humidity according to the aperture of temperature control, to through the stream 63A of sensible heat exchanger 58 and the stream stream 63B distribution of not passing through sensible heat exchanger 58 with air throttle 61; Mix then, via importing the pipe arrangement 63 guiding interior spaces.Thereby, through the aperture of control temperature control with air throttle 61, can the amount of regulating and distributing, can be with the air importing interior space that is adjusted to desired temperatures.That is, can indoor temperature be controlled to be set point of temperature (28 ℃).
In addition, under the vicissitudinous situation of indoor humidity, control device 70 control indoor humidity controls are with the aperture of open and close valve 66.Thus, flow through the changes in flow rate of the hot water of thermophore runner pipe 59, can indoor humidity be controlled at specified humidity.
Like this; Under the situation in summer; Can utilize outer gas air quantity, indoor temperature is controlled at 28 ℃, and; The surface temperature control that is present in the plate main body 7 among the radiant panel part 1a (the radiant panel part that is present in room area in the radiant panel 1) of room area to the major general becomes 23 ℃, utilizes the heat radiation of radiant panel part 1a to freeze.
[control during heating]
In this air-conditioning system S, refrigerator is used as steam pump, carry out heating operation.Under the situation of heating, the compressor 12 that sensible heat is handled with stream A1 moves to the rightabout of direction of rotation, and condenser 10 is as evaporimeter performance function; Evaporimeter 11 is as condenser performance function; Replace cooling tower 18, use the mechanism (for example, heating tower) that supplies with heat source water; Thus, sensible heat is handled with stream A1 and is constituted the steam pump circulation.In addition, the compressor 15 that latent heat is handled with stream B1 moves to the rightabout of direction of rotation, and condenser 13 is as evaporimeter performance function, and evaporimeter 14 is as condenser performance function.Then; Just often; The hot water that in sensible heat is handled with stream A1, is formulated as set point of temperature (26 ℃) is seen off from condenser (evaporimeter 11 when being equivalent to freeze) heat exchanger 26, utilizes heat exchanger 26 to be heated, and the hot water supply that is formulated as set point of temperature (25 ℃) is in radiant panel 1.In addition, in latent heat was handled with stream B1, the hot water supply that is formulated as set point of temperature (30 ℃) was in thermophore runner pipe 59.
Under the normal condition in when heating, supply with the hot water that is formulated as set point of temperature (25 ℃) continuously to radiant panel 1, the surface temperature of the plate main body 7 among the radiant panel part 1a is maintained set point of temperature (23 ℃), utilize heat radiation, the people is heated.Also have, 25 ℃ hot water is reduced to 23 ℃ through radiant panel 1, and flows out from radiant panel 1.In addition, room temperature is set at set point of temperature (20 ℃).
In such normal condition; When heat load reduces (for example, when people's number increases etc.), the surface temperature of the plate main body 7 among the radiant panel part 1a is than 23 ℃ of risings; Utilize temperature sensor T1 to detect the temperature that it has risen, this temperature detection signal is given to control device 70.Thus, control device 70 is exported the control signal of the frequency of the CD-ROM drive motor that reduces supply-water pump P3 corresponding to detected temperatures.Thus, the flow that passes through radiant panel part 1a of 25 ℃ hot water reduces, and the surface temperature of the plate main body 7 among the radiant panel part 1a reduces, and is controlled to be set point of temperature (23 ℃).Also have, at this moment, the flow of return condensed device (evaporimeter 11 when being equivalent to freeze) reduces, and therefore, for the vacuum with condenser (evaporimeter 11 when being equivalent to freeze) is maintained 26 ℃ saturation pressure, need reduce the output of compressor 12.Therefore, control device 70 is exported the control signal of the frequency of the CD-ROM drive motor M1 that reduces compressor 12 corresponding to detected temperatures.Thus, the hot water temperature who is supplied in radiant panel 1 is maintained 25 ℃ all the time.In addition; Follow the flow of 25 ℃ hot water to reduce; The degree of heating via the hot water of heat exchanger 26 Returning evaporimeters (condenser 13 when being equivalent to freeze) reduces, therefore, and corresponding to this; The frequency of control compressor 15 is controlled at set point of temperature (30 ℃) all the time with the hot water temperature who is supplied in cold-producing medium body runner pipe 49.
Secondly; Many people are arranged and under the situation of normal condition at room area; When to outdoor withdrawing from and number minimizing etc. when heat load is increased; The surface temperature of the plate main body 7 among the radiant panel part 1a is than 23 ℃ of reductions, utilizes temperature sensor T1 to detect the temperature that it has descended, and this temperature detection signal is given to control device 70.Thus, control device 70 is exported the control signal of the frequency of the CD-ROM drive motor that reduces supply-water pump P3 corresponding to detected temperatures.Thus, the flow that passes through radiant panel part 1a of 25 ℃ hot water increases, and the surface temperature of the plate main body 7 among the radiant panel part 1a rises, and is controlled to be set point of temperature (23 ℃).Also have, at this moment, the flow of return condensed device (evaporimeter 11 when being equivalent to freeze) increases, and therefore, for the vacuum with condenser (evaporimeter 11 when being equivalent to freeze) is maintained 26 ℃ saturation pressure, needs to increase the output of compressor 12.Therefore, control device 70 is exported the control signal of the frequency of the CD-ROM drive motor M1 that increases compressor 12 corresponding to detected temperatures.Thus, the hot water temperature who is supplied in radiant panel part 1a is maintained 20 ℃ all the time.In addition; Follow the flow of 25 ℃ hot water to increase; Hot water via heat exchanger 26 Returning evaporimeters (condenser 13 when being equivalent to freeze) is exceedingly heated, therefore, and corresponding to this; The frequency of control compressor 15 maintains set point of temperature (30 ℃) all the time with the hot water temperature who is supplied in thermophore runner pipe 59.
Like this; Even under the situation in the winter time; The surface temperature that is present in the plate main body 7 in the radiant panel part of neighboring area in the radiant panel 1 becomes the temperature more than 23 ℃, and the surface temperature that is present in the plate main body 7 among the radiant panel part 1a of room area at least is maintained 23 ℃.Its result is even be that inhabitation people H also can obtain comfort under 20 ℃ the situation in indoor temperature.
Secondly, indoor temperature and indoor humidity in winter are described.
At first, outdoor air utilizes air feed pipe arrangement 57 guiding total heat exchangers 53.Then, this air in total heat exchanger 53, and utilize room air to import between the air of the interior space of pipe arrangement 55 guiding and carry out total heat exchange.The temperature of the interior space and absolute humidity are the state higher than outdoor air, therefore, utilize the temperature and the humidity of air of the low temperature/low humidity of air feed pipe arrangement 57 guiding all to be enhanced.
Secondly, the air that has improved temperature and absolute humidity is directed to sensible heat exchanger 58, and passed through to carry out the sensible heat exchange between the air of damping unit 68.The air that has passed through damping unit 68 is high temperature like the back saidly, and therefore, the air that is guided by total heat exchanger 53 becomes the state that has only temperature to improve more under the state of having kept absolute humidity, and guiding damping unit 68.
In damping unit 68, make air through being supplied to around 30 ℃ the thermophore runner pipe 59 of hot water, thus, the temperature of air uprises.In addition, receive the supply of steam from humidifier, therefore, the absolute humidity of air uprises.Thereby the air that has passed through damping unit 68 becomes high temperature/many wet states.Like this, when humidification moves, before air passes through humidifier; The thermophore runner pipe 59 that utilization is supplied to hot water adds hot-air in advance, therefore, and through humidifier the time; Can make and contain a large amount of steam in the air, can efficient carry out the humidification of air well.
Passed through the high temperature of damping unit 68/many wet air in sensible heat exchanger 58,, kept under the state of absolute humidity being cooled with sensible heat exchange by the low air of the temperature of total heat exchanger 53 guiding, via in pipe arrangement 63 guide chamber below ground.Below ground air is from blow out to the top below ground in the guide chamber, receives the influence of the outer gas heat that imports at indoor people's liberated heat or from window etc. etc., and temperature and absolute humidity all rise.Also have, room air is via pipe arrangement 55 guiding total heat exchangers 53, and utilize between the outdoor air of air feed guiding and carry out total heat exchange.Thus, form the state that temperature and humidity all reduce by the air of indoor guiding, and to outdoor discharge.
When heating, also as stated, according to outer temperature degree, the control ventilation is with the aperture of air throttle 54.In addition, if indoor temperature change generated in case is then utilized temperature sensor T3 that it is detected, and temperature detection signal is given to control device 70.Control device 70 is according to detected temperatures, and the control of control temperature is with the aperture of air throttle 61.Thus, can indoor temperature be controlled to set point of temperature (20 ℃).In addition, under the vicissitudinous situation of humidity, control device 70 control indoor humidity controls are with the aperture of open and close valve 66.Thus, flow into the changes in flow rate of the hot water of thermophore runner pipe 59, can indoor humidity be controlled at specified humidity.
Like this, under the situation in the winter time, can utilize outer gas air quantity, indoor temperature is controlled at 20 ℃, and, the surface temperature control of the plate main body 7 among the radiant panel part 1a is become 23 ℃, utilize the heat radiation of radiant panel part 1a, heat.
Also have; Except the control of the control of the surface temperature of above-mentioned radiant panel and indoor temperature/indoor humidity; In above-mentioned air-conditioning system S, utilize temperature to take into account pressure gauge at suitable position, measure temperature and pressure as the water of working media; Be controlled at the temperature and the pressure of the water of circulation in the system, it is become in the desired range.For example, as shown in Figure 2, measure the temperature of the cold water that passes through respectively at the entrance side of the entrance side of radiant panel 1 and thermophore runner pipe 59; This temperature signal is handled the compressor of handling with stream B1 with compressor 12 and the latent heat of stream A1 15 to sensible heat transmit, and based on this temperature signal, by each compressor 12,15 control rotating speed; Or for example; A plurality of compressors are connected in series and under the situation about constituting at each compressor 12,15, the operation platform number of control compressor, for example; When refrigeration, above-mentioned cold water temperature is controlled to the value (20 ℃, 7 ℃) of regulation.
In the air-conditioning system of said structure; When the dehumidifying operation; Sensible heat exchanger 58 makes the outdoor air that passed through total heat exchanger 53 and through damping unit 68 and be removed between the air of low temperature of moisture and carry out the sensible heat exchange, therefore, and under the situation of the state that the moisture that can in being maintained the air that is supplied in the interior space, contain is few (state of dehumidifying); Efficient makes the temperature of this air heat once more well, can reduce at heating load once more.And then through the effect of sensible heat exchanger 58, can make the variations in temperature of the air of guiding damping unit 68 is low state, therefore, can reduce the live load as the thermophore runner pipe 59 of cool stream siphunculus performance function.Like this, through the effect of sensible heat exchanger 58 monomers, can be with the air that is supplied in interior space heating once more effectively; And, can reduce the live load of thermophore runner pipe 59, therefore; Can access and significantly economize the ability effect, and, can also realize the miniaturization of air-conditioning equipment.
In addition, when humidification moved, through the effect of sensible heat exchanger 58, under the situation of the state that the moisture that can in being supplied in the air of the interior space, contain is many, efficient reduced the temperature of this air well.And then; Can utilize the heat energy of the air that has passed through this damping unit 68, the temperature of the air of the guiding of heating damping unit 68, therefore; Can efficient reduce the live load as the thermophore runner pipe 59 of heating runner pipe performance function well, can access high province can effect.
