[Abstract]:In order to improve the temperature efficiency of the heat pipe system in the pump drive circuit, the feasibility of using the multi-loop system instead of the single loop system to recover the exhaust air energy of the air conditioning system is discussed. The prototype of the heat pipe system of the single-loop and three-loop pump driving loop is made. An experimental test platform was set up to study the heat transfer characteristics of single-loop and three-loop systems under summer and winter operating conditions, and based on the principle of uniformity of heat transfer temperature difference, a comparative analysis was carried out. The results show that the performance of the three-loop system is better than that of the single-loop system. When the indoor and outdoor temperature difference is 31.9 鈩，
