Summary

Proposed a new type of solar absorption refrigeration system with an integration of solar energy heat pump, analyzed their performance compared with the traditional system under a reasonable set of conditions. The results show; when the sun radiation intensity is high (0.95 kW/m2 ), the cooling capacity of the new system (A type) is 1.6 times the traditional system, the other new system (B type) is 3.07 times the traditional system, when the sun radiation intensity is low (0.2 kW/m2 ), the cooling capacity of the new system (A type) is decreased by 70 % compared to high radiation intensity conditions, the other (B type) is decreased only by 42.3 %, and the traditional system could not provide refrigeration; two new solar refrigeration systems can operate stably by regulate the water flow or compressor speed with solar radiation intensity varies; under the same evaporation and condensing temperature, R600a heat pump system has higher COP and less power consumption than R134a heat pump system under obtaining same cooling capacity; two new type of system was proved viable and economic through economy analysis.
