Air Energy

Does air energy use the energy of nature like solar energy and wind energy? Does air energy simply refer to air?

Air energy refers to the energy contained in the air, also known as air source. That is, the low-grade heat energy contained in the air.

As we all know, air is everywhere, which means that air energy is also everywhere.

In the law of conservation of energy, energy is always transformed from one form to another, or transferred from one object to another, and energy is conserved and does not arise or disappear out of thin air.

Of course, air energy also follows the law of energy conservation. Air energy is the ability of air to absorb energy and release it. The higher the temperature of the atmosphere, the greater the heat energy in the air.

There is a law in thermodynamics that heat will not cause other changes when it is transferred from a low-temperature heat source to a high-temperature heat source. In other words, air cannot be used without consuming external energy.

Conditions are required for air to be utilized. At this time, an air source heat pump is needed. This technology can absorb heat in the air and transfer it to high-temperature objects or environments.

However, when the heat pump is used and functions, it needs to consume electric energy or heat energy.

The air can heat the object by absorbing the heat source in the air, which can save energy, protect the environment and save energy, which brings convenience to people’s life. Air energy is another new type of energy developed and utilized by humans after wind energy, solar energy, and tidal energy. It has high energy efficiency and is low-carbon and environmentally friendly. After being used, it will not emit carbon dioxide or produce other harmful gases.

It is worth mentioning that air energy is a renewable energy source, so air energy has a high utilization value.

Any substance has a certain heat capacity, and air is no exception. The heat energy contained in the air is air energy.

However, according to the third law of thermodynamics, it is impossible for heat energy to flow spontaneously from a low-temperature environment to a high-temperature environment without causing other changes. So how do we use the thermal energy in the outdoor low-temperature ambient air for heating or hot water in winter? This requires a heat pump to achieve.

Analogous to a water pump, a water pump lifts water from a low-level place to a high-level place by inputting electrical energy, and a heat pump transfers heat energy from a low-temperature environment to a high-temperature environment by inputting electrical energy. Such a heat pump that uses air as a heat source is called an air source heat pump, and the heat energy transferred to the room by the air source heat pump for heating or hot water is what we call air energy.

In addition, there are water-source heat pumps, ground-source heat pumps, and so on. As for the working principle of the heat pump, it is realized by inputting electric energy to the compressor to compress the refrigerant, combined with the evaporator, condenser, throttling device, etc.

In addition, regarding the issue of energy saving and environmental protection of air energy, first of all, air source heat pumps consume electric energy, which is a renewable energy source and does not need to consume fossil energy, so it is environmentally friendly. Secondly, the general air source heat pump heating energy efficiency (COP) is about 3.5 (under the condition of 7°C in the outdoor environment), that is, for every unit of electric energy consumed, 2.5 units of air energy can be obtained from the outdoor environment, thereby outputting 3.5 units of air energy to the room. unit of heat energy.

Therefore, the use of air-source heat pumps for heating is of great significance in today’s smog-ravaged world of continuous consumption of fossil energy.
