This laboratory uses the thermal balance method to test the cooling capacity, heating capacity, power consumption, and C. of room air conditioning O.P.。 Its experimental state is close to the actual working state of room air conditioning, and the measurement results on the inside of the room can be verified by the measurement results on the outside of the room. Therefore, it is usually used as a benchmark laboratory for measuring the capacity of room air conditioning. The laboratory conditions comply with the requirements of GB/T 7725-2004 and JIS B 8615-1.

The measurement principle of this laboratory is to measure the performance of the air conditioner by balancing the cooling capacity and dehumidification capacity of the tested air conditioner during cooling, or the heating capacity during heating, by inputting (or extracting) heat and water; The test results are based on the results measured on the indoor side, with the outdoor side as a supplementary measurement for verification. The difference between the results measured on the outdoor side and the indoor side should be within ± 4%.
