Based on the requirements of current national standards for the preparation of do-mestic hot water by low valley electric heating,and from the perspective of low-carbon,energy-saving,and economy,the existing low valley electric heating system for preparing domestic hot water is optimized.Several feasible schemes and calculation methods for preparing domestic hot water by low valley electric coupling solar energy or air source heat pumps suitable for different scenarios are proposed.
