Research on refrigerating characteristic of compound heat-pump system with air source and accessory ground-water source

提出了一种以地下水辅助空气源热泵的新型双热源复合热泵装置,并设计出实验样机。针对夏季工况研究了地下水侧流量的变化对复合热泵系统性能参数的影响。实验结果表明,在最大负荷制冷工况时,采用少量的地下水作为辅助热源,可使系统制冷量提高约20%,系统能效比EER提高近65%。

A new - style double - sourse compound heat - pump device with air souroe and accessory ground - water source was put forward in this paper, and a experimental sample was designed and mounted. The influence of the flow change of the ground -water on the performanee parameter of eompound heat - pump system with air source and aeeessory ground - water source were studied towards the summer work condition. Under the maximum load work condition, the results show that refrigeration capacity of system may rise by 20% approximately and EER of system can increase about by 65% when adopting small amount of ground - water consumption as accessory heat source of air souree heat pump system.
