Compressor performance test system and test method thereof

Abstract

The invention provides a compressor performance test system and a test method thereof. The compressor performance test system comprises a compressor to be tested, at least two condensers, at least two calorimeters and a control unit, a temperature sensor, a pressure sensor and an electronic expansion valve are arranged between an inlet of each calorimeter and an outlet of the corresponding condenser, and a pressure sensor and a temperature sensor are arranged between the outlet of each calorimeter and a liquid storage device at intervals. According to the compressor performance test system and the test method thereof, the refrigerating capacity of the two or more evaporation sides and the heating capacity of the two or more condensation sides are obtained at the same time through the two or more calorimeter systems, and therefore the performance testing requirements of the compressor with the multiple evaporation temperatures and the multiple condensation temperatures are met.

Description

technical field [0001] The present application relates to the technical field of compressors, in particular to a compressor performance testing system and a testing method thereof. Background technique [0002] With the large-scale use of small refrigeration devices such as refrigerators, freezers and air conditioners in ordinary households, the electricity consumption of residents has also increased accordingly, and users have put forward higher requirements for the energy-saving effect of products. Depends on the working condition and performance of the compressor. The compressor has a direct impact on the cooling and heating effect, energy saving effect, service life, noise, etc. of the refrigeration device. Therefore, refrigeration equipment manufacturers put forward higher requirements for accurate testing of various thermodynamic parameters, noise and vibration of the compressor. The performance requirements for compressors are getting higher and higher, and more and ...

Problems solved by technology

[0003] However, the existing compressor performance testing devices generally only have one set of calorimeter side system, one set of condensing system and compressor suction state control unit, and can only test the compressor with one suction pressure and one discharge pressure. Cooling capacity, unable to simultaneously test the performance of compressors with multiple evaporating temperatures and multiple condensing temperatures, and cannot meet the performance test requirements of compressors with multiple evaporating temperatures and multiple condensing temperatures
