PURPOSE:To simplify the utility and save energy used for regeneration by connecting a high pressure gas line having solenoid valve and a high pressure liquid line to the regenerator, and disposing a tray to collect drain under the direct expansion coil and the regenerator. CONSTITUTION:Part of the high-temperature, high-pressure refrigerant gas which has been compressed by the compressor 56 enters into the regenerator 35 where it becomes a cooled high-pressure liquid by heating the open air OA, and the remainder enters into the condenser 45 where it is cooled by the exhaust air EA and drain to become a high-pressure liquid, and both of them enters into the receiver 58. The refrigerant which has been turned into a low-pressure liquid by an expansion valve 61a is evaporated by the direct expansion coil 34 to become a low-pressure gas, which returns to the compressor 56 via an accumulator 59. To describe the above processesing a wet air curve diagram, the open air OA at the point (a) comes to the point (b) after leaving a total heat exchanger 33, and then reaches the point (c) from the direct expansion coil 34 to be heated by the regenerator 35 on to the point (d) to ultimately be supplied to an animal room R. The exhaust air EA reduced to the point (e) in the animal room R becomes the point (f) upon leaving the exhaust side total heat exchanger 33. Since it then cools the condenser 45 along with the drain, it becomes the point (g) and then is discharged. |
