Brief Introduction to Air Source Heat Pumps

In recent years, air source heat pumps have gradually entered people's family life from the engineering field, but due to the inadequate promotion of the entire air source heat pump industry, most people still don't know how air source heat pumps work. If you want to have a more comprehensive understanding of air source heat pumps, follow Leomon to learn about it.

What is the role of air source heat pumps?

The "air source" in air source heat pumps refers to low-grade heat energy in the air. How to understand low-grade heat energy? It refers to the ubiquitous heat energy in the air that is difficult for humans to use, such as the heat energy of seawater, the heat energy emitted by organisms, and the heat energy released by the combustion of fossil fuels.

Since low-grade heat energy refers to heat energy that is not easy to use, high-grade heat energy is not difficult to understand. Naturally, it is heat energy that can be directly used by humans.

In a word, air source heat pumps can absorb low-grade heat energy that is difficult to use in the air and produce high-grade heat energy that can be directly used by humans.

How does an air source heat pump generate heat?

The heating process of the air source heat pump can be understood as the reverse process of the air conditioner, and the core material is still our common refrigerant.

When heat is not doing work, it will only transfer from the high temperature area to the low temperature area. The refrigerant of the air source heat pump is very low in liquid state, so it can absorb heat from the air. After absorbing a certain amount of heat, the refrigerant will be converted into gaseous energy. After these gaseous energies are compressed by the compressor, they become high-grade thermal energy. At this time, the high-grade thermal energy is transferred to the water in the water pipe through the condenser, and the water becomes the hot water we need after absorbing heat.

How much power does the air source heat pump consume?

During the heating process of the air source heat pump, the compressor consumes electricity, but 1kW of electricity can generate 4kW of heat. The work of the compressor is essentially a "four ounces to move a thousand pounds" state, which is very energy-saving and energy-saving. Compared with electric water heaters and electric floor heating equipment, air source heat pumps save energy by about 75%, and are the first choice for the new generation of energy-saving and emission reduction equipment.

Is the air source heat pump safe?

Coal, gas, electricity, these three "keywords" often appear in accident reports. But the three words "air source" are basically "insulated" from accidents, because the heating principle of air source heat pump gives it a unique safety advantage: no natural gas is used, no coal is burned, no open flames appear, there will be no hidden dangers of flammability and explosion; no electric heating rods are directly immersed in the water tank, which can eliminate the danger caused by leakage of electric auxiliary components. Therefore, the safety factor of air source heat pump is much higher than that of traditional equipment such as coal-fired boilers and electric water heaters.

What fields are air source heat pumps mainly used in?

As a representative product of renewable energy, air source heat pumps can be found all over the country. Clean heating projects in Beijing, Tianjin and Hebei in the north use air source heat pumps to replace traditional coal-fired heating on a large scale; Inner Mongolia Normal University uses Leomon air source heat pumps to provide hot water for the campus; Guangdong Conghua chick breeding base uses Leomon air source heat pumps to provide heating and cooling services for chicken houses; Hunan Vienna International Hotel uses Leomon air source heat pumps for invisible heating and cooling + hot water services.

It can be said that whether it is heating, commercial heating and cooling, or industrial and agricultural heating, as long as there is a need for heating and cooling, air source heat pumps can do the job.

After reading these five knowledge points, I believe everyone has a vivid understanding of air source heat pumps. Air source heat pumps use renewable energy - air heating. For my country, which emphasizes energy conservation, emission reduction and sustainable development, it is an indispensable and important product in future development.
