DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an air conditioner using an air cycle.

[0002]

2. Description of the Related Art Conventionally, as disclosed in Japanese Patent Application Laid-Open No. 62-102061, there has been known a cooling apparatus which includes a compressor, a heat exchanger, and an expander to perform an air cycle. This type of cooling device is configured to suck air into a compressor, compress the compressed air, cool the compressed compressed air with a heat exchanger, and then expand the compressed air with an expander to obtain low-temperature air. In the cooling device of the above publication, the obtained low-temperature air is supplied to the room to perform cooling. That is, the cooling device is used as an air conditioner.

In the cooling device disclosed in the above publication, a steam separator is provided between the heat exchanger and the expander to separate moisture from air sent to the expander. Here, when the air expands in the expander to a low temperature, dew condensation occurs in the air. For this reason, air is dehumidified on the upstream side of the expander to prevent dew condensation of the water. Further, the cooling device sprays water on the low-temperature air expanded by the expander. Then, the temperature of the air blown out from the expander is further reduced by the evaporation of the water, so that the cooling capacity is increased.

[0004]

As described above, in an air conditioner performing an air cycle, dehumidification or humidification is performed on air supplied to a room, and as a result, the humidity of the air is manipulated. I have. However, the conventionally performed operation of humidity of air is performed for convenience of operation. Therefore, the amount of dehumidification and the amount of humidification with respect to the air are determined in order to maintain the operating state appropriately, and the humidity of the air has not been manipulated in order to maintain the humidity of the room air appropriately.

To cope with this, it is conceivable to determine the amount of dehumidification and the amount of humidification with respect to air so that the indoor humidity is appropriately maintained. However, this makes it impossible to properly maintain the driving state, which may hinder driving. For example, if the amount of humidification is adjusted, the cooling capacity may decrease, and the indoor temperature may not be maintained properly. For this reason, in the above-mentioned conventional air conditioner, it was difficult to maintain both indoor temperature and humidity appropriately and to ensure comfort.

[0006] In addition, when the temperature control is emphasized and the humidity control is emphasized, the optimum operation state of the air cycle is usually different. For this reason, there is a problem that if one of the temperature control and the humidity control is emphasized, the other must be operated in a low efficiency state. Here, the sensible heat load and the latent heat load are different between summer and winter and the intermediate period. For this reason, in the above-mentioned conventional air conditioner, the operation in the optimum operation state can be performed only at one time of the year, and there has been a problem that high-efficiency operation cannot be performed throughout the year.

SUMMARY OF THE INVENTION The present invention has been made in view of the above circumstances, and an object of the present invention is to provide an air conditioner using an air cycle, which performs highly efficient air-conditioning operation throughout the year while maintaining indoor temperature and temperature. The purpose of the present invention is to appropriately control both humidity and ensure comfort.

[0047]

According to the above solution, the first cycle section (11) controls the temperature and humidity of the air, and the second cycle section (12) controls the temperature of the air.
Here, when the adjustment amount of the humidity is changed in the first cycle section (11), the adjustment amount of the temperature may be changed accordingly. When the first cycle unit (11) is configured to mainly perform humidity control, the first cycle unit (11)
May be insufficient for cooling load or heating load. On the other hand, in the above solution, the first
The shortage of the temperature control ability of the cycle section (11) can be compensated for by the second cycle section (12). Therefore, the temperature adjustment and the humidity adjustment can be performed separately, and both the indoor temperature and the humidity can be optimally adjusted to improve comfort.

Further, the first cycle section (11) is configured to be highly efficient at the time of humidity control while ensuring sufficient temperature control and humidity control performance as a whole, and the second cycle section (12) is controlled. It can be configured to be highly efficient during temperature control. Therefore, even when only one of the temperature adjustment and the humidity adjustment is performed, highly efficient operation can be performed using one of the first cycle unit (11) and the second cycle unit (12). Thus, highly efficient air-conditioning operation can be performed throughout the year.

According to the second solution, ventilation can be performed together with the adjustment of temperature and humidity, and the comfort can be improved.

In the third to eighth solutions, the first cycle section (11) takes in the outdoor air, dehumidifies and cools it, and supplies it to the room. And cooled and supplied indoors. Therefore, ventilation can be performed at the same time as cooling.
Furthermore, since the outdoor air is dehumidified and supplied to the room, it is possible to prevent a rise in humidity and maintain the room comfortably.

Here, the cooling load increases in summer, but is not so large in spring or autumn. On the other hand, ventilation must be provided in the spring and fall. On the other hand, in the spring and autumn, only the first cycle section (11) can respond to a small cooling load while performing ventilation, and in the summer, the second cycle section (12) can also be operated to increase the cooling load. Can respond. For this reason, it becomes possible to respond to a change in the cooling load while operating the first cycle section (11) and the second cycle section (12) with high efficiency.

In particular, in the fifth solving means, in the second cycle section (12), the second cycle air is cooled by the room air discharged outside the room. here,
The second cycle air is room air taken in from the room and is supplied to the room again. Therefore,
According to this solution, the cold energy of the discharged indoor air can be recovered to the second cycle air, and the energy loss due to ventilation can be reduced.

According to the sixth and seventh solutions, the cycle air can be cooled to a lower temperature in the heat exchangers (30a, 30b) by supplying moisture to the heat absorbing air. For this reason, it is possible to lower the air temperature at the inlet of the expander (22a, 22b). As a result, the input to the compressors (21a, 21b) can be reduced while maintaining the cooling capacity, thereby improving the COP (coefficient of performance).

Further, according to the eighth solution, the moisture in the cycle air can be continuously transferred to the heat absorbing air by the humidity medium of the humidity control means (60), and the cycle air is dehumidified. Can be performed continuously.

Also, in the ninth to sixteenth solving means,
One of the first cycle unit (11) and the second cycle unit (12) takes in outdoor air, heats it, and supplies it to the room, and the other takes in room air, heats it, and supplies it to the room. Therefore, ventilation can be performed at the same time as heating. Further, since the first heat absorbing air is humidified and supplied to the room, it is possible to prevent a decrease in humidity due to ventilation and maintain the room comfortably.

Here, the heating load increases in winter, but is not so large in spring or autumn. On the other hand, ventilation must be provided in the spring and fall. On the other hand, in the spring and autumn, the small heating load can be handled while ventilating only by the first cycle part (11), and in the winter, the second cycle part (12) is also operated to increase the large heating load. Can respond. For this reason, it becomes possible to respond to a change in the heating load while operating the first cycle section (11) and the second cycle section (12) with high efficiency.

In particular, in the eleventh and fourteenth solving means, in the first cycle section (11) and the second cycle section (12), the indoor air discharged outside the room is supplied to the air cycle circuit as cycle air. ing. Then, the compressed cycle air in the air cycle circuit (20a, 20b) exchanges heat with the endothermic air in the heat exchangers (30a, 30b). Therefore, according to the present solution, the heat of the exhausted indoor air can be recovered to the heat absorbing air, and the energy loss due to ventilation can be reduced.

According to the fifteenth solving means, the first heat absorbing air can be humidified by utilizing the moisture taken from the indoor air discharged to the outside. Therefore, moisture can be collected from the discharged indoor air, and the collected moisture can be supplied indoors together with the heat absorbing air. For this reason, it is possible to suppress a decrease in indoor humidity due to ventilation, and to suppress an increase in latent heat load due to ventilation.

Further, according to the sixteenth aspect, the moisture in the cycle air can be continuously transferred to the heat absorbing air by the humidity medium of the humidity control means (60), and the moisture absorbing air is dehumidified. Can be performed continuously.

Further, according to the seventeenth solution means, it is possible to switch between the cooling operation and the heating operation.

Further, according to the eighteenth and nineteenth means, the humidity medium of the humidity control means (60) can be constituted by using a solid adsorbent or a liquid absorbent. And the dehumidifying means (60) can be constituted corresponding to each humidity medium.

Therefore, during a period when the cooling load is large, such as in summer, the first cycle section (11) can reliably perform ventilation while appropriately maintaining indoor humidity, and the second cycle section (12) can perform the first cycle. The cooling capacity of the cycle section (11) can be supplemented to sufficiently cope with the cooling load in summer.
For this reason, by operating both the first cycle unit (11) and the second cycle unit (12) in an efficient operation state during a period of a large cooling load, the humidity and temperature can be sufficiently adjusted. It is possible to further improve ventilation by reliably performing ventilation.

By adjusting the cooling capacity, it is possible to avoid a decrease in the humidity control capacity and the equipment efficiency, and it is possible to operate the pump with high efficiency throughout the year.

Further, according to the second cycle section (12), the cold heat of the second heat-absorbing air, which is exhaust air from the room to the outside, can be recovered to the second cycle air. Therefore, the cold energy of the exhaust gas can be collected into the second cycle air and returned to the room, and the energy loss due to ventilation can be reduced.

The first heat absorbing side system (40a) and the second heat absorbing side system (40b) are provided with a precooler (41a, 41b) and a water introduction part (42a, 42b), respectively. Therefore, the temperature rise of the heat absorbing air in each heat absorbing side system (40a, 40b) can be suppressed, and the cycle air can be cooled to a lower temperature in the heat exchangers (30a, 30b). For this reason, it is possible to lower the air temperature at the inlet of the expander (22a, 22b). As a result, the compressor (21a,
21b) can be reduced, thereby improving the COP (coefficient of performance).
