摘要

为最大限度利用可再生能源，将太阳能PV/T集热器与热泵相结合组成太阳能-热泵复合供能系统，通过不同阀门之间的相互切换，可实现多种运行模式以满足人们对生活热水、采暖或制冷的需求。实验主要针对单空气源热泵制热、PV/T与水源热泵联合制热及PV/T与双热源热泵联合制热3种运行工况进行研究，分别从室内温度、制热量、热泵COP、集热效率、发电效率等方面对系统进行实验研究与理论分析，实验结果表明，3种运行工况下热泵COP分别为2.26、3.4和2.61，平均室内温度分别为15.3、18.8和16.5℃，基本能满足冬季采暖负荷要求。系统可充分利用太阳能与热泵各自的优势，实现能源节约，为太阳能和热泵在建筑中联合运行模式提供部分参考价值。

Abstract

To make the best use of renewable energy

a system of solar-heat pump composite energy was formed by combining solar PV/T collector with heat pump. Switching between the different valves can achieve many operating modes to meet people's need for hot water and heat and cooling. The experiment mainly studied three operating modes: single-air-source heat pump

solar PV/T collector with water-source heat pump

and solar PV/T collector with dual-heat-source heat pump. Indoor temperature

heat capacity

COP

thermal efficiency and electric efficiency were investigated experimentally and analyzed theoretically. Results showed that COP were 2.26

3.4 and 2.61

respectively

along with average indoor temperature of 15.3

18.8 and 16.5℃

which can basically meet the need for heating load in winter. The advantage of solar energy and heat pump were made full use and realized energy conservation

which provide some reference for solar and heat pump operation modes in buildings.
