Title:
CONTROL METHOD FOR BUILDING COMPREHENSIVE ENERGY SUPPLY SYSTEM OF PV/T COUPLED DUAL-SOURCE HEAT PUMP
Document Type and Number:
WIPO Patent Application WO/2023/231726
Kind Code:
A1
Abstract:
Provided is a control method for a building comprehensive energy supply system of a PV/T coupled dual-source heat pump. The comprehensive energy supply system comprises a solar heat storage cycle, a solar heat collection cycle, a hot water storage tank heat storage cycle, a direct heat supply cycle, a water source heat pump heat extraction cycle, a heat pump unit load side heat supply cycle, a ground source heat pump heat extraction cycle, a heat pump unit load side cold supply cycle, and a ground source heat pump heat supplementing cycle, implementing direct heat storage of solar energy to the ground. The heat collection efficiency, heat storage efficiency and PV/T power generation efficiency are improved, cold storage and heat storage can be achieved at the same time, large-span energy cascade utilization of the temperature of a hot water storage tank (3) from high grade to low grade is achieved, and the comprehensive utilization efficiency of solar energy is improved.
