摘要

热泵供暖可以解决燃煤供暖带来的环境污染问题，本文以和田地区应用的空气源热泵系统为研究对象，实验测试了采用辐射地板为末端的空气源热泵供暖系统的实际性能，在典型天（环境温度为-4.7~9.6 ℃，相对湿度为26%~61%）24 h内分析了各项性能参数的变化和室外环境温度变化对热泵供暖系统性能的影响。结果表明：在典型天的实际工况下，热泵供暖系统COP在16:00附近达到最高值2.64，在8:00附近达到最低值1.98。由于供暖建筑的保温性能相对较好，当室外温度发生变化时，房间内供暖温度波动较小；对于阳面房间，房间温度全天可稳定在23~24 ℃；对于阴面房间，房间温度也能达到20 ℃以上。采用辐射地板采暖为末端的空气源热泵供暖系统满足和田地区供暖需求，系统效率较高，应用前景广阔。

Abstract

Heat pump heating can solve the environmental pollution problems caused by coal heating. This study used an air source heat pump system applied in Hotan area as the research object and tested the in-situ performance of the air source heat pump heating system with the radiant floor within 24 h on a typical day (the ambient temperature was -4.7–9.6 ℃ while the RH was 26%–61%). The results show that the highest COP of the heat pump heating system is 2.64 at around 16:00

and the lowest value is 1.98 at around 08:00. Owing to the relatively good insulation performance of the building

when the outdoor temperature changes

the room temperature fluctuates slightly; the room temperature can be stable between 23–24 °C all day

and the room temperature can be above 20 ℃ even for northern rooms. The air source heat pump heating system using radiant floor heating can satisfy the heating demand of the Hotan area. The system has high efficiency and broad application potential.
