Embodiment

[0015] Such as figure 2 As shown, the process of this test system consists of two circuits, a refrigerant circulation circuit and a water circulation circuit.

[0016] In the refrigerant circuit, the saturated refrigerant gas from the calorimeter 4 enters the compressor 1 after being overheated; the refrigerant is compressed into a high-temperature and high-pressure gas and flows into the water-cooled condenser 2; after the water-cooled condenser 2 is subcooled The refrigerant becomes liquid, passes through the expansion valve 3, is throttled into a gas-liquid two-phase fluid, and enters the calorimeter 4. The refrigerant fluid evaporates in the calorimeter 4 and becomes a saturated gas. After being heated, it enters the suction port of the compressor 1 to complete the entire refrigeration cycle. In order to accurately calculate the refrigeration capacity of the compressor 1, refrigerant pressure measuring points 11, 13, 15, 17 and temperature measuring points 12, 14, and 14, res...

Abstract

The invention discloses a condensation heat-recovering type performance test system for refrigeration compressors, which comprises a refrigerant circulation loop and a water circulation loop. The system is characterized in that an air-source chiller in the water circulation loop is connected in parallel with a heat exchange coil in a calorimeter and then is connected with two ends of the heat exchange coil of a water-cooled condenser to form two parallel loops respectively, namely a main-path energy recovery water-flow loop and a bypass energy dissipation water-flow loop are used to heat second refrigerant and dissipate redundant heat into the surrounding environment through the air-source chiller respectively. As the test system links the calorimeter of the compressor test system with the condenser, and recovers part of condensation heat for heating the second refrigerant to replace the prior electric heating, the system can greatly reduce the energy consumption of system operation and save energy. As part of condensation heat is recycled, energy and heat needing to be dissipated are reduced, thus the energy consumption of the air-source chiller can be reduced.
