Abstract

PURPOSE:To effectively lower a temperature of the air to be supplied to a room to be air conditioned by a simple structure. CONSTITUTION:Part of the air of a room 1 to be air conditioned is discharged to a circulation air exhaust passage 9 connected to the room 1. Fresh air introduced into an atmospheric air introduction passage 6 and circulation air discharged from the room 1 to the passage 9 are combined in an air passage connector 8. The combined air flow is cooled by a plurality of heat exchangers 10, 14, 15. The exchanger 10 of the exchangers 10, 14, 15 is a heat exchanger for heat exchanging between the combined air and the circulation air. Since the circulation air is discharged from the room 1, its temperature is about the temperature (about 17-25 deg.C) of the room 1. Thus, the air (combined air) to be supplied to the room 1 is effectively cooled by the circulation air of low temperature (17-25 deg.C).

2. Description of the Related Art In a conventional air conditioner, air supplied to an air conditioning room is pressurized by a compressor, cooled by a heat exchanger, adiabatically expanded by a turbine and adjusted to a predetermined temperature before being supplied to the air conditioning room. is doing. In such an air conditioner, if the temperature of the air flowing into the turbine is kept low, the turbine outlet temperature will drop accordingly, so that the cooling capacity will be improved. When it is necessary to improve the cooling capacity, it is necessary to keep the temperature of the air flowing into the turbine low by the heat exchanger. When the air supplied to the air conditioning chamber is cooled by the heat exchanger, the air whose temperature has been increased by the compressor and whose temperature has risen (that is, the air supplied to the air conditioning chamber) is cooled by the external air having a low temperature. The temperature of the external air used by the heat exchanger is about 30 to 50 ° C. in a natural state. If the air having such a temperature is introduced into the heat exchanger, it is possible to sufficiently lower the temperature of the air supplied to the air conditioning chamber at the turbine inlet.

The circulating air is heated in the heat exchanger 10 and then mixed with fresh air in the air passage connecting portion 8. The mixed air of the fresh air and the circulating air circulates in the air conditioning room 1 via the compressor 13, the heat exchanger 14, the heat exchanger 15, the heat exchanger 10, and the turbine 17.
In this case, the circulation air is first discharged from the air-conditioning chamber 1 and takes heat when passing through the heat exchanger 10 to increase its temperature, and when passing through the heat exchanger 10 before flowing into the turbine 17, heat is circulated. Is taken away and the temperature drops. Thus, when the circulating air first passes through the heat exchanger 10, the temperature rises, and then the heat exchanger 1
If the temperature drops when it goes through 0, at first glance it seems that the energy efficiency does not change with or without the heat exchanger 10, but in reality it is better to provide the heat exchanger 10 with better energy efficiency. Can be improved. The reason is as follows.

When the heat exchanger 10 is used as in the above embodiment, the temperature of the mixed air of the circulating air (the circulating air that has been heated when first passing through the heat exchanger 10) and the fresh air is The temperature becomes higher than the temperature of the mixed air of the circulation air and the fresh air when the heat exchanger 10 is not used. In this case, the temperature of the mixed air flowing into the heat exchanger 14 is higher when the heat exchanger 10 is used. Heat exchanger 14
When heat exchange is performed between the mixed air and the ram air in, the greater the temperature difference between the mixed air and the ram air,
The amount of heat exchange between them is large. The temperature of the mixed air for heat exchange in the heat exchanger 14 is the same as that of the heat exchanger 1 as described above.
Since the temperature is higher when 0 is used, the temperature difference between the mixed air and the ram air is higher when the heat exchanger 10 is used. Therefore, when the heat exchanger 10 is used, the amount of heat exchange in the heat exchanger 14 can be made larger than in the case where the heat exchanger 10 is not used, so that energy efficiency is improved.
