摘　　要：在提出分离式螺旋热管蓄冷空调系统的基础上,建立了螺旋热管管外融冰放冷过程的理论模型;分析了蓄冷桶内融冰量及放冷量随时间的变化关系。研究结果表明,在蓄冷桶进口水温一定的情况下,外融冰的循环水流量越大,其融冰放冷过程就越快;在外融冰循环水流量一定的情况下,放冷过程随蓄冷桶进口水温的升高而加快。According to the cool storage air conditioning system with separated helical heat pipe, the analytical model of the ice melting on the separated helical heat pipe was established. The mass of ice in the ice storage tank and diseharging cooling capacity, which vary with time, were analyzed. The results indicate that the discharging time is shorter as the mass flow rate of water increases at constant return water temperature, and the discharging time is shorter as the return water temperature increases at constant the mass flow rate of water.
