Test bench of compressor performance (the second refrigerant calorimeter method)
Description

 

This test bench uses the second refrigerant calorimeter method to test compressor cooling capacity, input power and coefficient of performance ,etc. It is applicable to not only common refrigerants(R134a、R290、R22、407C、410A), but also new refrigerants (CO2,R404A) through customization.Its test condition can be adjusted according to different test standards, and it is kind of reliable calibration equipment. The test bench meets the requirements of standards GB/T5773 -2004 and ASHRAE23-78.
