The invention provides a compressor performance test system and method. A first end and a fourth end of a four-way reversing valve of the system are respectively connected with an exhaust port and anair suction port of a compressor, a second end is connected with a top interface of a calorimeter, a third end is connected with a first interface of a first coil, a bottom interface of the calorimeter is connected with a second interface of the first coil through a second two-way flow meter, a two-way valve and a first two-way flow meter in sequence, a first temperature sensor and a second temperature sensor are respectively used for sensing the temperature of a refrigerant flowing through the first interface and the second interface, a third temperature sensor and a fourth temperature sensorare respectively used for sensing the temperature of a refrigerant flowing through the top interface and the bottom interface, the four-way reversing valve comprises a first working state and a second working state, in the first working state, the first end and the second end of the four-way reversing valve are communicated, and in the second working state, the first end and the third end of thefour-way reversing valve are communicated. According to the system, the compressor can be tested by using various methods.
Description
technical field [0001] The technical field of compressor testing of the present invention relates in particular to a compressor performance testing system and method. Background technique [0002] The technical field of refrigeration and air conditioning is the most important field of application of compressors. It has the characteristics of wide application fields and large differences in working conditions. , are closely related to people's quality of life. In order to meet the different needs of different refrigeration equipment, the types of compressors are also designed to be diversified. At present, the main types of market applications include rotor type, scroll type, piston type, screw type, and centrifugal type. However, my country's current manufacturing enterprises still have a certain gap with the world's advanced level in the core technology of compressors, and there is still room for improvement in terms of safety, durability, work performance, noise, vibratio...
