摘要
针对空气源热泵冷热水机组在寒冷地区冬季使用时结霜、热效率低等问题 ,提出一种双级热泵系统 ,即由空气源热泵冷热水机组提供 1 0～ 2 0℃温水 ,作为水源热泵的低位热源 ,组成水源热泵供热系统。分析了这种系统的技术经济性 ,认为该系统是可行的 。
Aimed at solving frosting and low heating efficiency of heat pumps in cold regions, puts forward a twin heat pumps heating system that consists of an air source heat pump and a water source heat pump. The air source heat pump supplies 10-20 ℃ water as low grade heat source of the water source heat pump. Analyses the technical and economical features of the system. Considers that the system is practicable and has energy conservation and environment protection effects.
