AI Technical Summary
In extremely cold weather, the heat absorption capacity of the evaporator of an air source heat pump decreases, the compressor exhaust temperature increases, the COP decreases significantly, and energy consumption increases; electric boilers have low heating efficiency, high operating costs, and poor economic performance in areas without off-peak electricity pricing policies.
By coupling air source heat pumps with electric boilers for heat storage, and taking advantage of off-peak electricity policies, the air source heat pumps provide heating and store heat during off-peak hours, while the heat storage tanks provide heating during the day, and the electric boilers provide heating during extremely cold or peak hours, thus achieving multi-energy coupling and complementary heating.
By improving the system's COP, reducing gas consumption, and lowering operating costs, the system solves the problems of insufficient heat load and low efficiency of electric boilers in extremely cold weather, achieving energy-saving and economical heating results.
