摘要
为了解决北方寒冷地区冬季空气源热泵由于室外温度低而造成的制热效率低的问题,将太阳能热水系统与空气源热泵系统相结合,把原有的空气源热泵系统改为低温太阳能热水辅助空气源热泵系统,通过提高蒸发温度,改善其制热效果。本文介绍改造后的系统原理,对改造后的系统与原系统进行测试对比分析,发现低温太阳能热水辅助空气源热泵系统相对于空气源热泵系统,制热量约为后者的2.1倍,制热效率高,节能效果好。
In order to solve the low heating efficiency of air-source heat pump caused by outdoor low-temperature during the winter in the northern,solar heating system is added to the basic air-source heat pump system,and the original air-source heat pump system turns to be air-source heat pump assisted by low-temperature solar hot water.The heating efficiency is improved through increasing the evaporation temperature.The system principle after reform is described.The comparison analysis on the performance between the reformed system and the original one is conducted by tests.It is found that compared with the air source heat pump system,the air-source heat pump assisted by low-temperature solar hot water＇s heating capacity is about 2.1 times as the original one,with higher heating efficiency and better energy-saving performance.
