Abstract

The invention provides a closed refrigeration cycle test device measurement and control system which comprises a compressor and a condenser, an air outlet of the compressor is provided with a first exhaust pipeline, the first exhaust pipeline is connected with a condenser air inlet pipeline and a second exhaust pipeline, the second exhaust pipeline is connected with a compressor air inlet pipeline, and the second exhaust pipeline is provided with a compressor air inlet adjusting valve. The compressor air inlet pipeline is connected with an air inlet of the compressor, and the condenser is connected with the condenser air inlet pipeline; the condenser is connected with a liquid pipeline, the liquid pipeline is connected with an air inlet cooling pipeline, the air inlet cooling pipeline is connected with a compressor air inlet pipeline, and a compressor air inlet cooling expansion valve is arranged on the air inlet cooling pipeline. The system comprises the three processes of compression, condensation and throttling, the evaporation process is omitted, the number of evaporation devices is reduced, and then the occupied area is reduced.

Description

technical field [0001] The present application relates to the technical field of refrigeration, in particular to a measurement and control system for a closed refrigeration cycle test device. Background technique [0002] With the continuous improvement of energy efficiency requirements for refrigeration and air conditioning, the accuracy of energy efficiency prediction for compressor part load is increasingly demanding. Therefore, a refrigerant compressor test device is needed to test the performance of the compressor. In general, the performance test of the compressor must be filled with refrigerant, which forms a closed cycle through the four processes of compression, condensation, throttling, and evaporation. Liquid, the high-temperature and high-pressure liquid becomes a low-temperature and low-pressure liquid through throttling, the low-temperature and low-pressure liquid enters the evaporator, evaporates into a low-temperature and low-pressure gas in the evaporator, ...
