Air energy heat pump and solar energy complementary type hot water device

Abstract

The invention discloses an air energy heat pump and solar energy complementary type hot water device, which comprises an air energy heat pump, a regenerative heat exchanger, a heat pump heat exchanger, a hot water output heat exchanger, a solar energy hot water heat exchanger, a solar energy hot water circulating pipe, a solar energy heat collector and an expansion water tank, wherein a heating unit of the air energy heat pump is connected with the regenerative heat exchanger, the regenerative heat exchanger is provided with the solar energy hot water heat exchanger and the hot water output heat exchanger, the solar energy hot water heat exchanger is connected with a solar energy heat collector through the solar energy hot water circulating pipe, and a solar energy lower circulating pipeline is connected with the expansion water tank. The air energy heat pump and solar energy complementary type hot water device uses the air energy heat pump and a solar energy hot water system to form a double-energy hot water system, fully uses air heat energy, also change direct using of solar energy hot water into indirect using of the solar energy hot water, increases use rate of air heat energy and exchanges air indoor in time at the same time, keeps air fresh, further guarantees quality of the solar energy hot water, can heat at once when using, prevents bacteria growth, and keeps hot water to be used in health standard.

Description

technical field [0001] The invention belongs to the technical field of combined utilization of air energy heat pumps and solar energy, and in particular relates to an air energy heat pump and a solar energy complementary water heating device for household environment air purification, air heat energy recovery, and solar energy utilization. Background technique [0002] Air energy and solar energy are inexhaustible clean energy sources. The development of solar energy utilization technology is in full swing, but the utilization methods are basically limited to electricity and heat. Directly related to people's lives is the solar water heating system. Solar energy in the prior art mostly adopts the vacuum tube stuffy way to obtain hot water, which is recycled into the home environment for bathing and domestic hot water. Because the low-temperature hot water produced by this direct hot water method is easy to breed bacteria, the hygiene index is often unqualified, and it is ha...

AI Technical Summary

Problems solved by technology

Because the low-temperature hot water produced by this direct hot water method is easy to breed bacteria, the hygienic indicators are often unqualified, and it is harmful to the human body.

Cannot be used as drinking water

Some people will have skin allergies when taking a bath with solar hot water

Moreover, the solar water heating system of the prior art is easy to produce low-temperature stagnant water for the recycling of multi-storey buildings. Before using hot water each time, a lot of cold water needs to be drained, causing a lot of waste

In recent years, air energy heat pumps have been used in people's living environments, but their utilization methods are still relatively single, and most of them are used as hot water heat sources for bathing.
