A kind of coil auxiliary heating double tank type solar air energy water heater water tank

Abstract

The invention relates to a coil pipe auxiliary heating double-container type water tank of a solar and heat pump water heater. A water tank outer container is arranged in a water tank outer casing, a pressurizing water tank inner container is arranged in the water tank outer container, a solar circulating water inlet pipe and a solar circulating water outlet pipe are respectively arranged at the two sides of the lower part of the water tank outer container, a hot water outlet pipe and a vacuum heat insulation pipe are arranged at the top part of the pressurizing water tank inner container, one end of the vacuum heat insulation pipe is connected with a cold water inlet pipe, and a refrigerant heat exchange coil pipe is arranged in a gap between the water tank outer container and the pressurizing water tank inner container. The coil pipe auxiliary heating double-container type water tank has the advantages that by adopting the double-container structure of the water tank outer container and the pressurizing water tank inner container, the solar and heat pump water heating can be integrated, and the mutual influence on water quality caused by solar circulating water and domestic water is avoided; the structure is simple, the size is small, the manufacturing and installation are convenient, the running is stable, and the heat-insulation, energy-saving and high-efficiency effects are realized.

Description

technical field [0001] The invention relates to the comprehensive utilization technology of solar energy and air energy, specifically refers to an energy-saving, environment-friendly, high-efficiency, and stable household-type coil auxiliary heating double-tank solar air energy water heater water tank, which belongs to the technical field of solar energy and air energy water heaters. Background technique [0002] Commonly used heat sources for domestic water heaters in my country mainly include solar energy, air energy, electric energy, and gas. Solar water heaters use renewable solar energy resources, and basically do not need to consume other energy for operation; air energy water heaters are air energy utilization systems powered by electric energy. Compared with electric water heaters, their thermal efficiency is 300%-500% of electric water heaters my country's electric power production is still dominated by thermal power at present, and the operation of electric water he...

AI Technical Summary

Problems solved by technology

[0003] my country is a country rich in solar energy resources. In recent years, the research and application of solar water heaters in our country has developed rapidly. However, solar energy resources are greatly affected by seasonal changes and weather changes. The ability to produce hot water in winter is poor, especially in rainy weather. Even hot water cannot be produced during the day, therefore, solar water heaters often need to set up an auxiliary heat source

At present, the commonly used auxiliary energy for solar water heaters is electric energy. If the auxiliary electric energy is not properly controlled in actual operation, the electric energy consumption will be greater than the solar energy gain, and even under the same hot water consumption, the auxiliary power consumption of solar water heaters is greater than that of pure electric water heaters. Therefore, the selection of auxiliary heat sources for solar water heaters and the energy-saving design of hot water systems are important issues facing the development of solar thermal technology.
