【摘要】 为解决夏热冬冷地区冬季采暖问题,本文设计了空气源热泵结合小温差换热末端的分布式采暖空调系统。实验研究表明:在冬季典型工况下采用35℃左右的热水供暖,系统制热COP可达3.0;在夏季典型工况下采用10℃左右的冷水制冷,系统制冷COP也在3.0以上。结果表明通过使用小温差换热末端降低了机组设定出水温度,改善了机组的运行工况,提升系统的能效比。系统解决了目前空气源热泵在冬季低温工况下采暖能效低、舒适性差等问题,为解决我国南方冬季采暖问题提供了可行方案。更多还原

【Abstract】 This paper deals with an air-source heat pump（ASHP） space heating and cooling system with LowH₂O indoor terminals to solve the residential heating in South China.Experiment results show that the system has a total COP about 3.0 with ASHP outlet water temperature at 35 ℃ under typical operation condition in winter;and a total COP over 3.0 with ASHP outlet water temperature at 10℃ under typical operation condition in summer.It indicates by the use of low-H₂O terminal,the operation condition of ASHP is improved,thus has a better COP.This kind of system can overcome the typical problem（low energy efficiency and bad thermal comfort） of traditional ASHP heating system,providing an alternative solution for South China winter residential heating.更多还原
