Abstract

The invention discloses a frequency conversion refrigeration compressor motor performance test system. Comprising a refrigeration compressor, an exhaust stop valve, an exhaust air reservoir, a compressor performance test meter, a compressor performance test flow regulating valve, a condensing pressure test meter, a condenser, a drying filter, a refrigerant liquid flow regulating valve, an evaporation pressure test meter, an evaporator, a gas-liquid separator and a compressor suction flow control regulating valve which are connected through a circulation loop. The high-pressure end of the bypass valve is connected between the exhaust stop valve and the exhaust air storage cylinder, and the low-pressure end of the bypass valve is connected between the suction pressure test meter and the air return stop valve. The system has the functions of testing the highest pressure and different pressures of the refrigeration compressor, testing different condensation temperatures, testing different evaporation temperatures, testing different rotating speeds, testing different pressure differences and testing motor performance parameters under circulation operation by using different refrigeration working media, so that testing means under various working conditions are provided for the variable-frequency refrigeration compressor motor.

Description

【Technical field】 [0001] The invention relates to a motor performance test system of a variable frequency refrigeration compressor, which belongs to the technical field of performance test of a variable frequency refrigeration compressor motor. 【Background technique】 [0002] The refrigeration compressor is the core and heart of the refrigeration system, and it is also the core energy-consuming part of the refrigeration system. Among them, the compressor motor is the most direct and effective means to improve the efficiency of the refrigeration compressor and reduce energy consumption. As the earth's energy shortage situation is becoming more and more serious, various countries and regions pay more and more attention to energy conservation, and at the same time put forward higher and higher requirements for the efficiency of energy-consuming products. It is an effective way to achieve energy saving by using frequency conversion technology to best match the output of the refr...
