摘要/Abstract

摘要： 围绕建筑供暖需求，本文构建了太阳能集热/蒸发器和翅片蒸发器并联的直膨式太阳能热泵（direct expansion solar assisted heat pump，DX-SAHP）供暖系统，分析了系统热力循环过程，搭建了系统的工程应用实验平台，实验结果分析表明，DX-SAHP供暖系统在不同运行工况下可获得较高的性能，性能系数（coefficient of performance，COP）最高可达到6.88，压缩机频率、太阳辐照度和环境温度对系统的制热量和COP均有影响；压缩机定频运行时，太阳能集热/蒸发器运行的COP比翅片蒸发器大约高30%，变频运行时大约高45%，变频运行具有更优的性能。

Abstract: A direct expansion solar assisted heat pump (DX-SAHP) system for space heating with solar heat collector/evaporator and fin evaporator in parallel is constructed, the thermal cycle process of the system is analyzed, an experiment platform of the system is set up. The experimental results show that the DX-SAHP heating system can obtain high performance under different operating conditions. The highest COP can reached 6.88. Compressor frequency, solar irradiance and ambient temperature all affect the heating capacity and COP of the system. The COP of the system running with solar collector/evaporator is nearly 30% higher than that of the fin evaporator under constant frequency, and nearly 45% under conversion frequency. The system has better performance under conversion frequency operation mode.

Key words: direct expansion, solar assisted heat pump, solar collector/evaporator, performance analysis
