摘要

通过对比现有的空气源热泵空调系统的优缺点，提出了一种新型无霜空气源热泵空调系统。该热泵系统不仅冬季可以无霜高效运行，夏季性能也有所提升。搭建该系统实验平台，研究了室外空气干球温度、相对湿度、冷冻水、冷却水流量、室外空气流量对夏季工况系统性能的影响。该空气源热泵空调系统在湿度低、冷却水流速大、冷冻水流速大时系统性能有较大提升，COP最大可提升0.23，提高室外空气流量对系统性能影响不大可提升0.06，且在室外空气干球温度35℃相对湿度45%时，系统COP超过了该型压缩机额定COP，充分证明了该系统在夏季工况下能稳定高效运行。

Abstract

This paper reports an experimental research of a new type of air source heat pump system in summer. This system can operate efficiently in winter

and improve the performance in summer operation. Through constructing the experimental platform for heat pump system

the effects of outdoor air dry bulb temperature

relative humidity

chilled water flow rate

cooling water flow rate and outdoor air flow rate in summer conditions on system performance can be acquired. It is concluded that the COP of air source heat pump air conditioning system increases with the decrease of outdoor air humidity

the increase of cooling water flow rate and the increase of chilled water flow rate. The effects of outdoor air flow rate on system performance can be ignored. At the condition of outdoor air dry bulb temperature 35℃ and relative humidity 45%

the COP of system can reach 3.23

more than the COP of compressor rated

which fully demonstrated that the system can run stably and efficiently in summer.
