Multiple heat source complementary type heat-exchange hot-water supply system

Abstract

The invention discloses a multiple heat source complementary type heat-exchange hot-water supply system. The system mainly comprises a displacement heat exchanger, an inner circulation pump, a hot-water circulation pump, a heat pump circulation pump, an air source heat pump unit, a temperature control valve and a control cabinet, wherein the displacement heat exchanger is a vertical structure and provided with a first heat exchange coil, a second heat exchange coil, an electric heater, an inner circulation water distribution pipe and an inner circulation water outlet pipe inside, the inner circulation water distribution pipe and the inner circulation water outlet pipe are connected with a circulation pipe outside the displacement heat exchanger, the inner circulation pump is arranged on the circulation pipe, the bottom of the displacement heat exchanger is connected with the water inlet pipe, and then the water inlet pipe is connected with a cold-water supply pipe and a hot-water return pipe respectively. The hot-water for living is prepared in the multiple heat source complementary way including direct heating by air source heat pump unit and auxiliary heating by the heat media power supply pipes and the electric heater, the multiple heat source complementary heat-exchange hot-water supply system is energy-saving, safe and economical, and the using effect of hot water is ensured.

Description

technical field [0001] The invention relates to the technical field of concentrated hot water heat exchange, in particular to a multi-heat source mutual standby heat exchange supply hot water system. Background technique [0002] With the development of society and the improvement of living standards, centralized hot water supply systems are widely used in residences, hotels, offices, bath centers, clubs and other occasions. At present, most of the centralized hot water supply systems in the market use boilers, air source heat pump hot water units and other single heat sources to prepare domestic hot water, but the use of boilers to prepare domestic hot water is expensive and not conducive to low-carbon environmental protection, while air source heat pumps Although the hot water unit has high energy efficiency, its operating efficiency is not high when the ambient temperature is low in winter, and when the frost is severe in winter, the hot water unit may not operate normall...
