英文摘要 | A multiple energy assisted heat pump (MEABP) system for radiant floor heating was proposed, which integrated a domestic air-assisted heat pump with a solar water heater. The system mainly employed a vacuum tube solar collector with a surface area of 7.44 m(2), an electrical rotary-type hermetic compressor, two capillary tubes and three heat exchangers. All operation modes have functioned successfully in Lanzhou city, China. The experimental data of air-source heat pump (Mode 2) and double-source heat pump (Mode 3) have been discussed. The results show that the coefficient of performance (COP) of the MEAHP system and the COP of the space heating system (COPs) are around 2.2 and 1.9 with the room air at 19 degrees C, respectively, and the temperature difference of the inlet and outlet of the radiant floor heating pipes is 2.8 degrees C. Some methods to improve the system performance are put forward. |
