Résumé

In order to reduce the performance degradation caused by the heat loss of reversing valve in heat pump air conditioning system, a method of substituting lower thermal conductivity valve seat for present commonly used ones was proposed. The energy saving effect of lower thermal conductivity valve seat was analyzed through experiments and simulations. Research results show that, the heat loss of the present commonly used reversing valve cannot be ignored; considering the effect factors of structure design and processing technology, it is a feasible method to reduce heat loss by using reversing valve seat with lower thermal conductivity; when thermal conductivity of reversing valve seat decreases from 110 W/(m.K) to 60 W(m.K), the heat loss of reversing valve decreases by 21%, and the COP of heat pump system increases by 0.4%.
