Experimental Investigation on a Novel Dry-Expansion Evaporator in an Air-Cooled Heat Pump
摘要
Abstract
A novel turbulent flow self-supported dry-expansion evaporator based on unsymmetrical space heat transfer concept was presented in order to overcome poor heat transfer performance and high resistance problems of conventional baffle shell-and-tube dry-expansion evaporators. The new evaporator was installed and evaluated on an air-cooled heat pump. The results show that the cooling capacity of the air-cooled heat pump is 52.33 kW, and the cooling coefficient of performance (COP) is 2.47. Moreover, the heating capacity is 63.32 kW and heating COP is 3.0. Comparative experiments with the same type of air-cooled heat pump were tested using a conventional baffle shell-and-tube dry-expansion evaporator. The heat transfer area of the novel evaporator is reduced by 33.3%, and the cooling COP is increased by 6.0%. Moreover, the heating COP is increased by 15.8%and the amount of refrigerant charge is reduced by 7.1%.关键词
