太阳能-空气源复合热泵热水器的性能分析

Performance Analysis of Solar-air Source Hybrid Heat Pump Water Heater

针对空气源热泵低温时供热性能差和太阳能热利用时存在密度低、不稳定等情况,本文针对两种热源相结合技术弥补单一热源的缺点,充分发挥两种热源的供热优势,在设定太阳能进水流量0.3 m^(3)·h^(-1)、0.5 m^(3)·h^(-1)、0.7 m^(3)·h^(-1)3种模式下,对比分析两种系统的性能。

In view of the poor heating performance of air source heat pump at low temperature and the low density and instability of solar energy in heat utilization, this paper aims at the combination of two heat sources to make up for the shortcomings of a single heat source, give full play to the heating advantages of the two heat sources, and set the solar water inlet flow rate at 0.3 m^(3)· h^(-1), 0.5 m^(3)· h^(-1), 0.7 m^(3)· h^(-1)in three modes, compare the performance of the two systems in three modes.
