Theoretical analysis and experimental research of heat pump driving heat pipes heating equipment

In this study, the main design parameters of the heat pump/heat pipe composite system were calculated. The operation characteristics of the heat pump/heat pipe composite system under low temperature were experimentally studied. The start-up character of the heat pipe radiator and heat pipe radiator surface temperature distribution were obtained. The variation of heating capacity and heating coefficient of performaance of the heat pump/heat pipe composite system with different working condition was obtained. Experimental results show that the heat pump/heat pipe composite system can operate efficiently and steadily when the outdoor temperature is ?20~5?C, and meet the winter heating demand in cold areas. nema
