Operation Conditions Analysis on Solar Energy Compression-Injection Secondary Refrigeration System

Abstract:

The COP of compression-injection secondary refrigeration system is increased by 20%-50% than traditional compression-injection system. This paper analyzes the operation conditions on generation temperature, intermediate cooling temperature, condensation temperature and evaporation temperature in the compression-injection secondary refrigerating system powered by solar energy. Comprehensively considering technical and economic factors, the results show that generation temperature should be increased and condensation temperature should be decreased. In addition, the area of solar heat collector and the COP of the system should be considered when we chose the intermediate cooling temperature.
