Above-mentioned storage heater 36 is energy storing liquid composition and the storage heater that only gas componant is re-supplied to compressor 18 types, therefore, can only the gas componant of the first thermal medium be supplied to compressor 18 reliably.
As this storage heater 36, can use the storage heater of accumulator by type.
In addition, also the cooling water of discharging from heat dump 32 can be supplied to water purifior 35, and spray from the spray nozzle 15a of spray nozzle group 15.In the situation that the temperature of the cooling water of discharging from heat dump 32 is higher than the temperature of the cooling water of supplying with from pipe arrangement 33, because the evaporation of water latent heat from spray nozzle 15a ejection is less, therefore, the temperature that can reduce air stream reduces.
Even storage heater 36 is not set, the thermal medium of the gasification that heats up and be fed into cooler 16 and the thermal medium of evaporation collaborates from being inhaled into the gas heat absorption space cell 10 in as long as can make in heat dump 32 from the air stream heat absorption, and it is re-supplied to compressor 18 gets final product.
Yet, utilize expansion valve 34 to make the first thermal medium adiabatic expansion after the interior heat release of heater 14 and cooling, but the adiabatic expansion in expansion valve 34 produces cooling in, there is no the heat exchange between the first thermal medium and outside.Therefore, insulated the first cooling thermal medium, can be from being fed in cooling water heat dump 32, as the second thermal medium and absorbing heat via condenser 26 by outside.
Therefore, the first thermal medium of the high temperature of discharging from compressor 18, can will utilize the heat dump 32 of heat pump assembly from from outside, supplying with the compression kinetic energy that the energy absorbed next cooling water is applied to compressor 18.Can only utilize the driving-energy of the compressor 18 that makes the first thermal medium circulation, carry out the heat absorption of this heat dump 32.
In addition, in temp and humidity regulator shown in Figure 1, the cooling water of supplying with from outside is fed into heat dump 32 via condenser 26.Therefore, the part of the energy of the first thermal medium from high temperature that also use condenser 26 can be removed is applied to from the first thermal medium of the high temperature of compressor 18 discharges, thereby can improve the heating efficiency of heating channel.Therefore, except the energy that the heat dump 32 that utilizes heat pump assembly absorbs, the part of the energy of the first thermal medium from high temperature that use condenser 26 can also be removed is applied to from the first thermal medium of the high temperature of compressor 18 discharges, thereby can improve the heating efficiency of heating channel, consequently, the temperature regulating range of air stream can be enlarged, and the energy can be realized significantly saving.
And, above-mentioned heater 14 can not only increase considerably the heating efficiency to this air stream, can also increase considerably the heating efficiency to the moisture from spray nozzle 15a ejection, and can increase considerably the humidification ability, therefore, also can enlarge the humidity regulation scope of air stream.
Like this, even because of the pure water of the spray nozzle group 15 ejection ormal weights of the supply side of being located at air, cause the reduction of the airflow temperature of the heater 14 that heating efficiency improved, also have and can airflow temperature be warmed up to the heating efficiency of set point of temperature by the heat absorption of heat pump assembly.
At this, in the situation that heat pump assembly is not set, spray nozzle group 15 is set and attempts humidity regulation, may occur air stream can not being adjusted to set point of temperature situation, air stream is adjusted to the situation that set point of temperature will take a long time.
That is, the reduction of the airflow temperature caused for the water because of from spray nozzle group 15 ejection, the heater 14 of the part of the first thermal medium of the high temperature of discharging from compressor 18 of need to increasing supply add heat.
Yet, be fed in the first thermal medium of heater 14 and only have the heat that compressor 18 applies.
Therefore, this is because in the situation that in order to regulate humidity, increase rapidly the amount of moisture of supplying with from spray nozzle group 15, can not towards heater 14, supply with air stream is warmed up to the required enough heats of set point of temperature at once.
Like this, in temp and humidity regulator shown in Figure 1, can therefore, the heating efficiency of regulation electric energy and humidification ability be increased considerably by the heating efficiency that arranges to improve this heating channel of heat pump assembly, and can realize saving the energy.
In addition, in temp and humidity regulator shown in Figure 1, can continuously change in fact according to the temperature in space cell 10 allotment ratio of the first thermal medium and the first thermal medium of the high temperature that is assigned to the cool stream trackside that proportion of utilization triple valve 20 is assigned to the high temperature of heating channel side.
Therefore, in temp and humidity regulator shown in Figure 1, in heating channel and cooling flowing path, supply with all the time the first thermal medium that high temperature is arranged, proportion of utilization triple valve 20 comes minor adjustments at once to be assigned to the allotment ratio of the first thermal medium of the high temperature of heating channel and cooling flowing path, thereby can tackle rapidly the small load change of air stream of temperature and humidity regulation object of the cooler 16 of heater 14 by heating channel and cooling flowing path, can improve response.
In addition, temp and humidity regulator as shown in Figure 1 is such, and pure water is from the spray nozzle ejection of the air intake side of being located at heater 14, thereby airborne humidity can be maintained to setting.In addition, during air circulation in dust free room, circulated air is by fan 12 heating such as grade, but, due to the spraying heat extraction of the pure water by from spray nozzle group 15, therefore, can reduce the load to cooler 16.
Consequently, can be with respect to temperature and the humidity of the air stream that sets value the temperature and humidity regulation object of controlling accurately the cooler 16, spray nozzle group 15 and the heater 14 that pass through heating channel, variations in temperature and the humidity that can reduce space cell shown in Figure 1 10 change, thereby the desired operation of Precision Machining can be set.
In temp and humidity regulator shown in Figure 1, as mentioned above, improved the heating efficiency of heating channel, and on stream, be respectively equipped with independently in the stream that comprises heating channel and cooling device, from the ratio triple valve 20 as distributor to the first thermal medium by cooler 16 and heat dump 32 respectively the stream that comprises heating channel till storage heater 36 interflow and comprise the stream of cooling flowing path.Therefore, the first thermal medium that temperature is different can not mix, and can enlarge the temperature regulating range of temperature and humidity regulation object.
In addition, even in the situation that increase substantially the design temperature of the air stream of the temperature and humidity regulation object by heater 14 and cooler 16, compared with proportion of utilization triple valve 20, the first thermal medium of high temperature is assigned to the allotment ratio of cooling flowing path, increase substantially the allotment ratio that is assigned to heating channel, also the air stream of temperature and humidity regulation object can be adjusted to rapidly to set point of temperature.
Even when regulating the temperature of above-mentioned air stream, humidity control part 27 also can be regulated the spray amount from the pure water of spray nozzle group 15, arrive and set humidity with the humidity regulation by air stream.
In addition, in temp and humidity regulator shown in Figure 1, improve the heating efficiency of heating channel, and do not needed to use other moisture feedway, the heater such as heating steam generation device, therefore, can realize significantly saving the energy.
In temp and humidity regulator shown in Figure 1, temperature control part 22 and humidity control part 27 are regulated temperature/humidity independently, even but in the situation that change design temperature, set humidity, the temperature/humidity of air stream also can reach design temperature/setting humidity in the short period of time.
In temp and humidity regulator shown in Figure 1 described above, on the pipe arrangement 30 that cooling water is supplied to condenser 26, be provided with the control valve 40 as refrigerant controller.Control this control valve 40, so that the discharge pressure of compressor 18 is certain.As shown in Figure 2, be provided with bar-shaped section in above-mentioned control valve 40, this bar-shaped section has the spool 40b of the peristome that opens and closes the 40a of valve section in the stream of being located at cooling water.This bar-shaped by the direction application of force of the spring 40c with its front end face butt towards the peristome of the spool 40b shut off valve 40a of section.In addition, the other end of bar-shaped section and the bellows 40d butt of supplying with the pressure that first thermal medium of discharging from compressor 18 is arranged, make bar-shaped section overcome the active force of spring 40c, and towards the direction of the peristome of opening the 40a of valve section to the spool 40b application of force.
Therefore, when the discharge pressure of compressor 18 becomes the active force of spring 40c when above, utilize bellows 40d that spool 40d is moved towards the direction of opening the peristome of the 40a of valve section, the cooling water inflow of the condenser 26 of increasing supply, thereby the cooling capacity of raising condenser 26.Like this, improve the cooling capacity of condenser 26, and reduced the discharge pressure of compressor 18.
On the other hand, when the discharge pressure of compressor 18 becomes the active force of spring 40c when following, spool 40d moves towards the direction of the peristome of the 40a of shut off valve section, reduces the cooling water inflow that supplies to condenser 26, thereby reduces the cooling capacity of condenser 26.Therefore, improved the discharge pressure of compressor 18.
Like this, remain necessarily by the discharge pressure by compressor 18, can the runs steadily temp and humidity regulator.In addition, towards condenser 26, supply with and surpass the cooling water inflow needed, and can regulate so that cooling water is not discharged outside system.
As shown in Figure 1, for above-mentioned control valve 40, be provided with valve 41 on the shunting pipe arrangement of control valve 40.This valve 41 in the situation that control valve 40 break down, the increase supply quantity delivered of the first thermal medium of high temperature of heater 14, reduce the discharge pressure of compressor 18, in the situation that, because the deficiency for feedwater makes the inoperative in fact grade of heat dump 32, supply feedwater towards condenser 26 and heat dump Final 32 system.
In temp and humidity regulator shown in Figure 1, between cooler 16 and heater 14, be provided with the spray nozzle group 15 of ejection pure water, but as shown in Figure 3A, also can spray nozzle group 15 be set at the outlet side of the air of heater 14.Like this, even spray nozzle group 15 is located to the outlet side of the air of heater 14, also can utilize heated air stream in heater 14 to heat and evaporate from the water droplet of spray nozzle group 15 ejections.
In addition, as shown in Figure 3 B, cooler 16 and heater 14 also can be set, after at air, being fed into heater 14, again it be supplied to cooler 16, and spray nozzle group 15 is located between cooler 16 and heater 14.In this case, also can utilize heated air stream in heater 14 to heat and evaporate from the water droplet of spray nozzle group 15 ejections.
In addition, as shown in Figure 3 C, also can adopt the heater 14 shown in Fig. 3 B and the setting of cooler 16, and spray nozzle group 15 is located to the entrance side of the air of heater 14.In this case, can utilize heater 14 directly heat and evaporate from the water droplet of spray nozzle group 15 ejections.
But, for example, as shown in Figure 3 D, in the setting of adopting the heater 14 shown in Fig. 3 A with cooler 16, and spray nozzle group 15 is located in the situation of entrance side of air of cooler 16, because the water droplet from 15 ejections of spray nozzle group is condensed and is not evaporated in cooler 16, can not be from air stream, removing, therefore, the humidity that air stream is adjusted to regulation is difficult.
As shown in Fig. 3 B and Fig. 3 C, in the situation that spray nozzle group 15 is located to the upstream side of heater 16 or cooler 14, than spray nozzle group 15, be positioned at downstream, heater 16 or cooler 14 works as the separator of the water droplet from 15 ejections of spray nozzle group, and can make the size of water droplet contained in the air stream of heater 16 by downstream or cooler 14 certain.
As shown in Figure 4, can use 2 two-way valves is two-way valve 38a, 38b, replaces the ratio triple valve 20 as the distributor used in temp and humidity regulator shown in Figure 1.Two two-way valve 38a, 38b are controlled by temperature control part 22 respectively.Utilize said temperature control part 22 to regulate each the aperture of two-way valve 38a, 38b, regulate in fact continuously by the first thermal medium of the gasiform high temperature of compressor 18 compressions/heating and be assigned to the allotment ratio of heating channel and cooling flowing path, and will be controlled at set point of temperature by the air stream of heater 14 and cooler 16.Now, regulate the aperture of two-way valve 38a, 38b and regulate continuously pro rate, so that be assigned to the first thermal medium amount of high temperature of heater 14 sides and the total amount of the first thermal medium amount that is assigned to the high temperature of cooler 16 sides equates with the first thermal medium amount of high temperature from compressor 18 discharges.
Now, as shown in Figure 5, minute other valve opening of two-way valve 38a, 38b and the relation of flow are not linearities.Therefore, in temperature control part 22, keep shown in Figure 5 and two-way valve 38a, 38b relevant discharge characteristic data respectively, according to each discharge characteristic of two-way valve 38a, 38b, towards each two-way valve 38a, 38b, send the aperture signal from temperature control part 22.
At this, " regulate and distribute in fact continuously the allotment ratio of heating channel and cooling flowing path " or " regulating and distributing in fact continuously ratio " refers to and drive two-way valve 38a, 38b utilizing substep to control, while regulating the allotment ratio of heating channel and cooling flowing path, the aperture of two-way valve 38a, 38b is driven and regulates by substep on microcosmic, but is driven and regulate continuously on the whole.
In temp and humidity regulator shown in Figure 1, utilizing during 16 pairs of air streams as the temperature and humidity regulation object of heater 14 and cooler carry out temperature and humidity regulation, for example, in the situation that heater 14 and cooler 16 are positioned at heated side with respect to the air stream of temperature and humidity regulation object, under the stable operating condition of air themperature, as shown in Figure 6A, use 14 pairs of the heaters cooled air stream of device 16 that is cooled to heat.Under the operating condition shown in Fig. 6 A, have following situation: needed energy A compares with heated air flow, uses the energy quantitative change of heater 14 heating large.In this case, as shown in Figure 6B, if can reduce as far as possible the energy of the repetition of heater 14 and cooler 16, can realize saving the energy.
On the other hand, in the situation that heater 14 and cooler 16 are positioned at cold side with respect to the air stream of temperature and humidity regulation object, under the operating condition of the temperature stabilization of air stream, as shown in Figure 7 A, use 16 pairs of air after heater 14 heating of cooler to carry out cooling.Under the operating condition shown in Fig. 7 A, have following situation: needed energy B compares with cooling-air stream, uses the cooling energy quantitative change of cooler 16 large.In this case, as shown in Figure 7 B, if can reduce as far as possible the energy of the repetition of cooler 16 and heater 14, can realize saving the energy.
But, in the supply of on-off control towards the first thermal medium of the high temperature of heater 14 and cooler 16, so that the heat of offsetting each other is while being zero, the running of temp and humidity regulator becomes unstable, and air stream reaches in set point of temperature, and to stablize the required time longer.Therefore, for can steady running temp and humidity regulator, the Min. of the heat that adds in the amount of cooling water that heat and cooler 16 apply, offsets each other that need to arrange that heater 14 applies.
The minimal heat of offsetting each other of this necessity is different slightly different because of temp and humidity regulator, therefore, preferably comes by experiment to obtain in advance.
Like this, in temp and humidity regulator shown in Figure 8, utilize compressor control section 44 (below, sometimes also referred to as compressor control section 44), inverter 42 via the rotating speed control part of the rotating speed as controlling compressor 18 is controlled, with the heat that adds in the amount of cooling water that heat and cooler 16 applied, offsets each other that reduces as much as possible that heater 14 applied, thereby can reduce the energy of cooler 16 and the repetition of heater 14.
In the structural elements that forms temp and humidity regulator shown in Figure 8, member mark with the symbol of Fig. 1 identical symbol identical to the structural elements of the temp and humidity regulator with shown in Figure 1, and description is omitted.
Temperature control part 22 interactions of above-mentioned compressor control part 44 and control ratio triple valve 20, the heat that adds in the amount of cooling water that heat and cooler 16 apply, offsets each other that reduces as far as possible that heater 14 applies, the Temperature and Humidity Control of the line space of going forward side by side air-flow.
By the control of the ratio triple valve 20 that utilizes temperature control part 22 to carry out with utilize the control of the rotating speed of the compressor 18 that compressor control section 44 carries out to be shown in the flow chart of Fig. 9.
As can be known after test running temp and humidity regulator shown in Figure 8, in the situation that temp and humidity regulator is positioned at the cold side running with respect to air stream, from in steady running, preferably will as heater 14 apply add heat, to be ratio triple valve 20 be made as 5~15% (ratio triple valve 20 is made as to 95~85% towards the apportionment ratio of the first thermal medium of the high temperature of cooler 16 sides) towards the apportionment ratio of the first thermal medium of the high temperature of heater 14 sides.
As can be known on the other hand, in the situation that temp and humidity regulator is positioned at the heated side running with respect to air stream, from in steady running, preferably will as heater 14 apply add heat, to be ratio triple valve 20 be made as 95~85% (ratio triple valve 20 is made as to 5~15% towards the apportionment ratio of the first thermal medium of the high temperature of cooler 16 sides) towards the apportionment ratio of the first thermal medium of the high temperature of heater 14 sides.
Therefore, in the control shown in the flow chart of Fig. 9, in the situation that temp and humidity regulator is positioned at the cold side running with respect to air stream, control the rotating speed of compressor 18, so that heater 14 apply add heat, particularly ratio triple valve 20 is 5~15% towards the apportionment ratio of the first thermal medium of the high temperature of heater 14 sides, in the situation that temp and humidity regulator is positioned at the heated side running with respect to air stream, control the rotating speed of compressor 18, so that above-mentioned apportionment ratio is 95~85%.
In flow chart shown in Figure 9, after in step S10, starting compressor 18, the temperature signal of measuring according to the temperature sensors 24 of being located in space cell 10, change continuously the allotment ratio of the first thermal medium that proportion of utilization triple valve 20 is assigned to the high temperature of heater 14 sides and cooler 16 sides, in step S12, to make air stream become set point of temperature, thereby the air stream that will be drawn in space cell 10 is adjusted to set point of temperature.
In step S14, judge whether above-mentioned air stream arrives set point of temperature stable, in the unsettled situation of the temperature of air stream, return to step S12, change continuously the allotment ratio that proportion of utilization triple valve 20 is assigned to the high temperature thermal medium of heater 14 sides and cooler 16 sides.Above-mentioned steps S12 and step S14 carry out in temperature control part 22.
On the other hand, in the situation that the air stream in space cell 10 arrives set point of temperature stable, in step S16~S22 judgement be assigned to heater 14 sides high temperature the first thermal medium allotment ratio whether within the limits prescribed.This step S16~S22 carries out in compressor control section 44.
Because there is deviation in the allotment ratio of the first thermal medium of the high temperature that is assigned to heater 14 sides, therefore, the mean allocation rate of the first thermal medium of high temperature shown in Figure 9 is the average value of the apportionment ratio of the first thermal medium in the stipulated time, below, sometimes referred to as the mean allocation rate of the first thermal medium.
At first, in step S16 and step S18, while supposing that temp and humidity regulator is positioned at cold side with respect to air stream, judgement towards the mean allocation rate of the first thermal medium of heater 14 sides whether in 5~15%.
At this, towards the mean allocation rate of the first thermal medium of heater 14 sides in the situation that in 5~15%, because temp and humidity regulator is positioned at cold side with respect to air stream, and be in the stable scope of temp and humidity regulator running, therefore, by step S16, and turn back to step S16 from step S18.
On the other hand, in the situation of the mean allocation rate less than 5% of the first thermal medium of heater 14 sides, because the mean allocation rate of the first thermal medium towards heater 14 sides is too low, therefore, it is unstable that the running of temp and humidity regulator easily becomes.Therefore, enter step S24 from step S16, increase the rotating speed of compressor 18, to increase towards the mean allocation rate of the first thermal medium of heater 14 sides.In step S24,42 send the increase signal that increases the rotating speed of the compressor 18 that inverter 42 sets with minimum change from compressor control section 44 towards inverter.By with minimum change, increasing the rotating speed of compressor 18, can the runs steadily temp and humidity regulator.

In addition, in the situation that surpass 15% towards the mean allocation rate of the first thermal medium of heater 14 sides, by step S16 and step S18, be judged as air stream not in cold side, and enter step S20 and step S22.In step S20 and step S22, while supposing that air stream is positioned at heated side, judgement towards the mean allocation rate of the first thermal medium of heater 14 sides whether in 95~85%.
At this, towards the mean allocation rate of the first thermal medium of heater 14 sides in the situation that in 85~95%, air stream is positioned at heated side, and be in the stable scope of the running of temp and humidity regulator, therefore, by step S20 and from step S22, turn back to step S16.
On the other hand, surpass in 95% situation towards the mean allocation rate of the first thermal medium of heater 14 sides, too high towards the mean allocation rate of the first thermal medium of heater 14 sides, it is unstable that the running of temp and humidity regulator easily becomes.Therefore, enter step S24 from step S20, increase the rotating speed of compressor 18, to reduce towards the mean allocation rate of the first thermal medium of heater 14 sides.In step S24,42 send the increase signal that increases the rotating speed of the compressor 18 that inverter 42 sets with minimum change from compressor control section 44 towards inverter.
In addition, in the situation that towards the mean allocation rate less than 85% of the first thermal medium of heater 14 sides, in step S22, be judged as air stream neither in heated side also not at the state of cold side, be adding in the amount of cooling water that heat and cooler 16 apply of applying of heater 14, the more state of heat of offsetting each other.Therefore, enter step S26, reduce the rotating speed of compressor 18.In step S26,42 send the reduction signal that reduces the rotating speed of the compressor 18 that inverter 42 sets with minimum change from compressor control section 44 towards inverter.With minimum change, reduce the rotating speed of compressor 18, make air stream transfer to heated side or cold side.
Then, enter step S28 by step S24 or step S26, judge whether compressor 18 is on-stream, if compressor 18 is on-stream, return to step S14.In step S14, judgement is in step S24 or step S26, and under the state of the rotating speed that increases or reduce compressor 18 with minimum change, whether the air stream in space cell 10 reaches set point of temperature stable.In the situation that the air stream in space cell 10 reaches set point of temperature stable, by step S16~step S26, again judge towards the mean allocation rate of the first thermal medium of heater 14 sides whether in prescribed limit.
On the other hand, in step S14, in the unsettled situation of the temperature of the air stream in being judged as space cell 10, return to step S12, continuously change the allotment ratio that proportion of utilization triple valve 20 is assigned to the first thermal medium of heater 14 sides and cooler 16 sides.Air stream in space cell 10 reach set point of temperature and stable after, enter step S16~S26.
