Heat preservation water tank for air source water heater

Abstract

The invention discloses a heat preservation water tank for an air source water heater. The heat preservation water tank comprises a water tank inner container, a water tank body, a third-level condensation copper coil pipe, a secondary condensation copper coil pipe and a primary condensation copper coil pipe; the water tank inner container is arranged in the water tank body, the position between the water tank inner container and the water tank body is filled with a polyurethane foaming heat preservation layer, a pollution discharge plug is mounted at the bottom of the water tank body, the bottom side of the water tank body is connected with a cold water pipe, the upper side of the water tank body is connected with a hot water pipe, the top of the water tank body is connected with a hot air discharge pipe and an overflow pipe, and the primary condensation copper coil pipe, the secondary condensation copper coil pipe and the third-level condensation copper coil pipe are mounted in the water tank body; the heat preservation effect is good, the structural strength is high, the use convenience degree of the water tank is improved, the heat exchange efficiency is high, the heating effect is good, on the liquid seal pipe segment, gas-state media can be effectively prevented from flowing out in a non-complete condensation manner, sufficient cooling heat exchange of the media is ensured, and the heat exchange efficiency and effect of the water tank can be improved.

Description

technical field [0001] The invention relates to the technical field of water heaters, in particular to an insulating water tank for an air source water heater. Background technique [0002] Air source water heaters are also called air source heat pump water heaters. The air source water heater absorbs the low-temperature heat in the air, vaporizes it through the fluorine medium, and then compresses it through the compressor to increase the temperature, and then converts it into the water for heating through the heat exchanger. The air source water heater has the characteristics of high efficiency and energy saving, and produces the same heat. The water volume is 4-6 times that of ordinary electric water heaters, and its annual average thermal efficiency ratio is 4 times that of electric heating, with high energy efficiency. [0003] The air source water heater needs to store the water after it is heated. Therefore, the insulation water tank is an essential and important par...

Problems solved by technology

[0003] The air source water heater needs to store the water after it is heated. Therefore, the insulation water tank is an essential and important part of the air source water heater. The current insulation water tank is usually a tank for storing water, which is wrapped with an insulation layer to reduce The heat is lost, but when the air source water heater heats the water and pumps it to the heat preservation water tank, part of the heat will be lost through the pipeline, the heat loss is serious, and the heat exchange efficiency of the air source water heater is not high, and the medium is steam during heat exchange Failure to fully condense, part of the medium in the vapor state is discharged together with the condensed liquid medium, resulting in insufficient heat release, reducing the heat exchange efficiency of the air source water heater and reducing the heating effect on water
