The working principle of air energy

Air energy is an environmentally friendly and efficient energy utilization technology widely used in fields such as heating, refrigeration, and hot water supply. It utilizes the thermal energy contained in the air, which is commonly present in nature, to provide thermal energy output. This article will provide a detailed introduction to the working principle of air energy and its applications in different fields.

1、 The Basic Principles of Air Energy

The basic principle of air energy is to use heat pump technology to extract low-temperature heat energy from the ambient air, and through compression and circulation processes, increase the temperature and transmit it to the system that needs heating or cooling. The heat pump system consists of the following main components:

Evaporator: In the evaporator, the refrigerant exchanges heat with air, thereby absorbing heat energy from the air and undergoing a phase change into a gaseous state.

Compressor: The function of a compressor is to compress low-temperature and low-pressure gas refrigerant into high-temperature and high-pressure gas.

Condenser: The condenser is another heat exchanger in a heat pump system, where the refrigerant exchanges heat with the medium in the heating or cooling system, releasing heat and converting it back into a liquid state.

Expansion valve: An expansion valve is a device that controls the flow of refrigerant, transforming it from a high-pressure liquid state to a low-pressure liquid state, ready to enter the evaporator for the next cycle.

The working principle of an air energy heat pump is similar to a regular refrigeration cycle, but its key lies in its ability to extract renewable heat energy from the natural environment, without relying on fossil fuels.
