THEORETICAL ANALYSIS AND EXPERIMENTAL RESEARCH OF HEAT PUMP DRIVING HEAT PIPES HEATING EQUIPMENT

ABSTRACT
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 COP 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℃, and meet the winter heating demand in cold areas.
