氨吸收式太阳能热泵-板式换热器联合供暖系统的理论与试验研究
Theoretical and Experimental Study on Ammonia Absorption Solar Heat Pump - Plate Heat Exchanger Combined Heating System
摘要
Abstract
This paper constructs a trough solar collector,ammonia absorption heat pump and plate heat exchanger combined heating system and discuss the optimal combination between the trough solar collector and the plate heat exchanger. The solar guarantee rate is 30%,40%,50% and the design heat load of plate heat exchanger is 20%,30%,40%,50% of the construction load. The mathematical model is used to calculate the combination of the solar energy guarantee rate and the plate heat exchanger heat transfer.After a comprehensive analysis,the system achieves the optimal matching relationship when the solar guarantee rate is 45% and the design load of plate heat exchanger takes up 30% of the construction load.In this matching relationship,the system COP is 3.11 and the supplementary heat is 520 kW·h. The results show that the measured value and the calculated value error of the outlet temperature of the heat-conducting oil are 11%,and the measured value and calculated value of water supply water temperature are 3%.The error is within the allowable range to verify the correctness of the proposed mathematical model.关键词
