Abstract

The invention discloses a hierarchical heating type domestic hot water storage and supply system and a control method of the hierarchical heating type domestic hot water storage and supply system. The hierarchical heating type domestic hot water storage and supply system comprises a hierarchical heating type water storage system used for storing heated water in a hierarchical mode according to water temperature, a water replenishing system, a hot water heating system, a hot water supplying system used for outputting the hot water in the hierarchical heating type water storage system, and an automatic control system, wherein the water replenishing system, the hot water heating system, the hot water supplying system and the automatic control system are connected with the hierarchical heating type water storage system. According to the hierarchical heating type domestic hot water storage and supply system and the control method of the hierarchical heating type domestic hot water storage and supply system, the hierarchical heating type domestic hot water storage and supply method and the intelligent control method are adopted, hot water and cold water are layered naturally according to the temperature gradient, gradient utilization of energy resources is facilitated, the inlet water temperature of a heat pump water heater is low, the condensation temperature of the system is lowered, the energy efficiency ratio is high, and energy resources are saved; the hierarchical heating type domestic hot water storage and supply system is reasonable in design, efficient, capable of saving energy, high in water temperature control precision, stable in outlet water temperature, high in use comfort, and capable of reducing environment pollution.

Description

technical field [0001] The invention relates to the technical field of hot water storage and supply systems, in particular to a step-by-step domestic hot water storage and supply system and a control method thereof. Background technique [0002] At present, heat pump water heaters are used to prepare domestic hot water, and the way of centralized storage and supply of hot water is widely used in hotels, restaurants, hospitals, high-end apartments, swimming pools and other public buildings. Compared with traditional electric boilers or Gas boilers have the advantages of energy saving and environmental protection. [0003] However, the traditional domestic hot water storage and supply system uses single-stage water storage for the preparation, storage and supply of hot water, as shown in the attached figure figure 1 As shown, the single-stage water storage is fused together due to the internal water body, including the hot water injected by the heat pump water heater 2-3, the...
