Abstract: The solar-assisted cold water phase-change energy heat pump system is a clean energy heating system which can effectively reduce the ice melting energy consumption of the cold-water phase-change energy heat pump system. In this paper, the operation mode of the solar-assisted cold-water phase-change energy heat pump system is given, three new ice melting methods are proposed, the performance of three ice melting modes using solar energy for thermal ice melting are simulated, and the influence of ice thickness on system operation is analyzed. The results show that among the three ice melting modes, the affected serial dual-source heat pump mode has the largest system COP, and the pure serial dual-source heat pump mode has the smallest annual total cost. Among the solar collector price, glycol price and electricity price, the change in solar collector price has the greatest impact on the total annual cost, and the change in glycol price has the least impact on the total annual cost. When the ice thickness exceeds 8 mm, the increase in the space heating of the solar-assisted cold water phase-change energy heat pump system becomes smaller, and the increase in heat consumption of ice melting becomes larger. The solar-assisted cold-water phase-change energy heat pump system can simultaneously melt ice and heat, and its economic benefits are significant, with good application and promotion value.
