Research Of Sub-absorption System Of The Absorption And Compression Hybrid Cycle Heat Pump Driven By Solar Energy

Due to the fact that the global energy crisis is getting more serious in the current period, efficient and environmental friendly energy has become an essential research subject in the practice of production nowadays. The supply and demand chain of current global energy market emphasize a series of characteristic such as diversification, cleanness, efficiency and globalization in order to better deal with the increasingly severe global problems such as shortage of energy, environment pollution, abnormal climate and etc.Due to the seasonal advantages, the solar absorption heat pump can greatly reduce the carbon emission and help relieve the difference between the peaks of electric power. However, the solar absorption heat pump also has its disadvantages of low efficiency and unstable operation.This article would discuss how the solar driven hybrid absorption/compression system combines the respective advantages of absorption subsystem and compression subsystem.This research is to verify the efficiency and practicality of the absorption/compression hybrid driven by solar heat pump system, and further study on the relative issue of new type heat pump system test bench. The major content of research is as below:1.Illustrations of the advantages and disadvantages of the traditional mechanical heat pump system and the application of the solar power, residue heat and wasted heat. Obtain the signification of the absorption/compression hybrid heat pump system by analysis, and introduce the current domestic and foreign backgrounds of the absorption/compression hybrid heat pump system。2.Illustrations of the multi-operation mods of the summer/winter absorption/compression hybrid system, calculation of the efficiency of the heat power of the new type absorption/compression hybrid cooling/heating cycle, analysis of the changes of the energy the absorption subsystem generates, when the temperature of cooling water, hot water and R22changes.3.By means of condenser/evaporator, the coupling of absorption subsystem with compression subsystem would improve the performance of the hybrid system via the refrigerant of the cold compression subsystem. Therefore, analyze the external conditions which can influence the performance of the absorption subsystem:the out- let temperature for refrigerant water, the temperature of the heated water, the inlet temperature for refrigerant R22, the flow rate of both the cooling water and R22. Apart from these above, the fouling factor would also influence the performance of the unit system.4.Through experiments, analyze the influences of the external conditions on the performance of the system, and summarize the regular pattern of these influences.
