Abstract
Proposed a new type of solar absorption refrigeration system with an integration of solar energy heat pump,analyzed their per_formance 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 sys_tem 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.关键词
