Circular ring pipe auxiliary heating double-liner-type solar-energy air-energy water heater water tank

Abstract

The invention relates to a circular ring pipe auxiliary heating double-liner-type solar-energy air-energy water heater water tank. According to the circular ring pipe auxiliary heating double-liner-type solar-energy air-energy water heater water tank, the technical scheme that a pressure-bearing water tank inner liner and an ordinary pressure water tank outer liner are arranged inside an outer shell of a water tank is mainly adopted, the upper side portion of the water tank outer liner is in close contact with the lower side portion of the pressure-bearing water tank inner liner, and is separated from the pressure-bearing water tank inner liner through the bottom face of the pressure-bearing water tank inner liner; a D-shaped circular ring pipe heat exchanger is arranged on the outer wall of the pressure-bearing water tank inner liner, and is in close contact with the outer wall of the pressure-bearing water tank inner liner by adjusting a connecting device; the two sides of the lower portion of the water tank outer liner are provided with a solar energy circulating water inlet pipe and a solar energy circulating water outlet pipe respectively, the top of the pressure-bearing water tank inner liner is provided with a hot water outlet pipe and a vacuum heat insulation pipe, and one end of the vacuum heat insulation pipe is connected with a cool water inlet pipe. By adopting the double-liner structure, the solar energy water heating and the air energy water heating are integrated together, solar energy circulating water and domestic hot water do not influence the water qualities of each other, and the water tank is simple in structure, convenient to manufacture and install, stable in operation and high in heat preservation and energy conservation efficiency.

Description

technical field [0001] The present invention relates to the technology of comprehensive utilization of solar energy and air energy, specifically refers to a household-type circular tube auxiliary heating double-tank solar air energy water heater water tank which is energy-saving, environmentally friendly, high-efficiency and stable operation, and belongs to the technical field of solar energy and air energy water heaters . Background technique [0002] Solar energy is a kind of clean energy. In today's increasingly serious environmental pollution, solar water heating technology will be more and more favored by people. According to expert calculations, based on the amount of heat required to heat water to 35°C, the cost per ton of hot water consumed by electric and gas water heaters is three times that of solar water heaters. my country is a country rich in solar energy resources, but solar energy resources are greatly affected by seasonal changes and weather changes. The ab...

Problems solved by technology

[0003] The combination of solar energy and air energy hot water technology still has some technical problems to be solved, such as: First, solar water heaters are often designed as unpressurized water tanks, while air energy water heaters are mostly designed as pressurized water tanks. The two hot water production technologies require Solve the problems of shared water tanks, simple equipment, and low investment; second, when the refrigerant heat exchange coil of the air source heat pump is placed directly in hot water, the copper material coil will corrode the hot water if it is placed in hot water for a long time. When the heat exchange coil is placed outside the inner tank of the water tank, the heat transfer coefficient will be affected; thirdly, when the heat exchange coil is placed outside the inner tank of the water tank, the temperature change along the length direction of the coil during the heat exchange process will affect the coil heat transfer and The quality of hot water in the tank may be affected
