The main performance indicators of the compressor are: input, output power, coefficient of performance, cooling capacity, starting current, running current, rated voltage, frequency, cylinder volume, noise, etc. To measure the performance of a compressor, mainly from three aspects of weight, efficiency and noise.
According to China's standards, the performance test of high and low temperature alternating wet heat box compressors is carried out according to the provisions of GB9098-96. The main items are cooling capacity, input power, working current, starting performance, residual moisture and impurity content of the machine, and life test. The safety performance test is carried out according to the items specified in GB4706.17-96. The main items are anti-electricity, insulation resistance, leakage current, operation test under locked conditions, as well as motor winding temperature rise, housing temperature and shutdown test.
