摘要
在剖析空气源热泵现有除霜技术弊端的基础上,提出一种基于改变系统流程的新型除霜技术,并与现有除霜技术进行对比计算分析。研究结果表明:在蒸发温度为-30℃,冷凝温度为50℃时,在一个除霜周期内,该系统COP可比逆向除霜技术提高28%。
A new defrosting technology based on reforming system flow is put forward after analyzing the disadvantages of existing defrosting technologies applied to air-source heat pump. Furthermore, this new technology is compared with the existing defrosting technology by calcu- lation and analysis. The research results show that when the evaporating temperature is - 30 ℃ and the condensing temperature is 50 ℃, the COP of the system can be enhanced by 28 % compared with that of reverse cycle defrosting technology.
