Air energy heat pump unit capable of absorbing solar energy in all weathers

Abstract

The invention discloses an air energy heat pump unit capable of absorbing solar energy in all weathers. The air energy heat pump unit comprises a low-temperature heat exchanger, a compressor, a high-temperature heat exchanger and an expansion valve which are sequentially connected, and the heat source side of the low-temperature heat exchanger is provided with an air energy absorbing device and a solar cell panel; the air energy absorbing device comprises a shell and an air energy heat exchange pipe arranged in the shell, the shell is provided with an air inlet and an air outlet, and the air energy heat exchange pipe is located on an air flowing path between the air inlet and the air outlet; the solar cell panel is provided with a solar heat exchange pipe; a heat source outlet of the low-temperature heat exchanger is connected to an inlet of the air energy heat exchange pipe, an outlet of the air energy heat exchange pipe is connected to an inlet of a solar heat exchange pipe, and an outlet of the solar heat exchange pipe is connected to a heat source inlet of the low-temperature heat exchanger. According to the air energy heat pump unit, utilization of air energy and utilization of solar energy are effectively combined, two types of natural sources, namely the air energy and the solar energy are utilized, non-renewable resources are not used any more, operation cost is lowered greatly, and pollution to the environment is lowered.

Description

Technical field [0001] The invention relates to an air energy heat pump unit capable of absorbing solar energy all-weather. Background technique [0002] Both solar energy and air energy are inexhaustible natural resources that exist naturally in nature. At present, people have been very effective in using solar and air energy. For example, solar water heaters and air energy heat pumps, solar water heaters use solar energy to heat water for people’s domestic hot water use; air energy heat pumps are a kind of low-grade heat energy that can be obtained from the air in nature. The high-grade thermal device used. However, these two energy acquisition devices have certain defects. Although solar water heaters have strong heat absorption capacity, large water production, and good thermal insulation performance, they are greatly affected by the weather and can only be used during the day when there is sunlight, at night, and on cloudy and rainy days. When there is no sunlight, it can...

Problems solved by technology

However, these two energy harvesting devices have certain defects. Although solar water heaters have strong heat absorption capacity, large water production, and good thermal insulation performance, they are greatly affected by the weather and can only be used during the day when there is sunlight, and at night, on rainy days, etc. When there is no sunlight, it cannot absorb sunlight to produce hot water. Therefore, it is not easy to guarantee the 24-hour hot water supply for users

Although the air energy heat pump unit can obtain a large amount of energy from the air, and the energy efficiency is relatively high, but the air energy is a low-grade energy, which makes the speed of obtaining energy from the air slow. In the prior art, air energy and solar energy are both It can be used alone and cannot be used in combination at the same time, and it is not easy to overcome their respective use defects
