Energy-saving sanitary type hot water supply system

Abstract

The invention discloses an energy-saving sanitary type hot water supply system. The system is mainly composed of a solar heat collector, an air source heat pump unit, a heat source control box, a heat source circulating pump, a displacement heat exchanger, a hot water sterilization device, a hot water circulating pump, a control cabinet and a hot water pipe network. The solar heat collector is in parallel connection with the air source heat pump unit, and the solar heat collector and the air source heat pump unit are each connected with a heat source water supply pipe for water inlet; a water returning part of the solar heat collector and a water returning part of the air source heat pump unit are each connected with a heat source water returning pipe; the heat source water supply pipe and the heat source water returning pipe are each connected with the arranged displacement heat exchanger, and the displacement heat exchanger comprises a first heat exchange unit and a second heat exchange unit; and the outlet water portion of the displacement heat exchanger is connected with the hot water supply pipe, and the hot water sterilization device is arranged on the hot water supply pipe. The energy-saving sanitary type hot water supply system has the beneficial effects of being sanitary, energy-saving, efficient, safe, environmentally friendly, good in using effect and the like, and the system is a centralized hot water supply system which can be widely applied to houses, hotels, offices, markets, bath centers and the like.

Description

technical field [0001] The invention relates to the technical field of hot water, in particular to an energy-saving and hygienic hot water supply system. Background technique [0002] With the development of society and the continuous improvement of people's living standards, people's requirements for domestic hot water supply are getting higher and higher. The relevant national standards propose that the quality of domestic hot water should meet the requirements of the current national drinking water quality standards, but the domestic hot water system has different characteristics from the cold water supply system. The temperature of the return water is 45°C, and the temperature of some hot water in the pipeline is between 35°C and 40°C. When the temperature of the hot water is lower than 55°C, it is not easy to kill various bacteria that breed in warm water, especially Legionella such pathogenic bacteria. Therefore, establishing domestic hot water disinfection assurance...

AI Technical Summary

Problems solved by technology

At present, domestic hot water disinfection assurance technology is mainly divided into chemical disinfection and physical disinfection. Chemical disinfection (such as chlorine, chlorine dioxide and ozone, etc.) can kill most pathogens, but there are disinfection by-products, and in hot water It is not easy to control and add in the system; physical disinfection is more suitable for the disinfection of residential and public building hot water systems, such as ultraviolet disinfection, metal ion disinfection, thermal sterilization, etc., and has good use effect and application prospects
