Performance tests research of residential central air-conditioning

The relations of air-conditioning between daily temperature test results and standard condition test results are researched. Aiming at Xinfei 13.6 kW residential central air-conditioning, the corresponding relations of the unit refrigerant performances between daily temperature and standard condition are made by lots of standard condition test and daily temperature condition tests. The main functions of the unit properties, refrigerant quantity-environment temperature equation, the input power-environment temperature equation and the COP environment temperature equation have been got by regressing the test data using least square method. The figures being analyzed, the concept "The Buffer Refrigerant Temperature" is put forward.
