Air source heat pump is currently the most mature, economical and easiest way to implement, and is naturally the most conducive to large-scale popularization:
1) The Most Mature Technology:
In 1824, Carnot published a paper and proposed the “Carnot cycle” theory, which was the origin of the air energy heat pump.
In 1852, British scientist Kelvin proposed the first formal heat pump system “heat multiplier”, which was the world’s first air energy heat pump.
From the early 1980s to the late 1990s, “heat pump heat” appeared in my country, and air source heat pumps were rapidly popularized in hotels, campuses and other facilities of enterprises and institutions.
In recent years, with the implementation of the “coal to clean energy” measures, my country’s air energy heat pump industry has received unprecedented development opportunities.
It can be seen that the development of air source heat pump has a history of nearly 200 years.
It has been developed in my country for nearly 50 years, and technological iteration and application have been very mature.
In comparison, my country’s water source and ground source heat pumps gradually attracted the attention of the academic and business circles after entering the 21st century.

2) The Most Economical:
Compared with ground source and water source heat pumps, its initial investment is lower, and it is most suitable for domestic or small and medium-sized commercial building applications.
3) The Easiest to Implement:
The air source heat pump has a wide range of applicable temperatures and small geographical conditions, and is not affected by bad weather such as overcast, rain, snow, and winter nights, and can be used normally.

|Air Source Heat Pumps Advantages
|1) Wide range of applications:
hot and cold,
Suitable for a wide temperature range,
and can be used all year round,
Not affected by bad weather such as overcast, rain, snow and winter nights,
can be used normally.
2) Low operating air source heat pumps cost: outstanding energy-saving effect;
Compared with solar water heaters with gas, electric, and electric auxiliary heating,
Lowest fees throughout the year.
3) Environmentally friendly products: no pollution and no combustion effluent,
Will not cause damage to the human body.
|1) Facilitate centralized management:
According to the size of the park and the staged construction, one or several water heat pump units are set up.
Easy to manage by installments.
2) Hot and cold supply:
For the requirements of public buildings that need cold and heat sources, one machine has multiple functions.
3) No waste, clean, and environmentally friendly:
Water source heat pumps utilize the energy of groundwater resources.
Compared with electric boiler heating, a water source heat pump saves more than two-thirds of the electricity.
Compared with fuel boilers, it saves more than half of the energy,
Thereby reducing carbon emissions.
|1) Low operating cost:
The ground source heat pump utilizes the relatively stable characteristics of the underground temperature throughout the year,
The COP value is as high as 4 or more.
2) Energy saving and environmental protection:
The indoor side is transported by chilled water, reducing the refrigerant charge,
thereby reducing air pollution;
The outdoor heat exchange environment is changed from the atmosphere to soil or water,
Thereby reducing atmospheric heat emissions and reducing the heat island effect.
During operation, no gas that pollutes the environment such as carbon dioxide is generated.
It will not affect the health of indoor personnel due to leakage.
|Air Source Heat Pumps Disadvantages
|1) The thermal efficiency is relatively low:
Since air energy is a decentralized energy source,
Heating is slow.
2) It is prone to frosting problems:
In extremely low temperature environments,
There is less heat in the air,
The heat energy that can be converted is limited,
Work efficiency will be greatly reduced.
|1) Water source conditions are limited:
In some cities, in order to protect the groundwater source from being polluted,
It is forbidden to extract and utilize; water source heat pumps that utilize river and lake water,
It is also affected by many factors such as seasonal water level decline.
There are many restrictions on the use of water source heat pumps.
2) The initial investment is relatively high, the system is complex, and the installation is difficult:
Ground source heat pumps have relatively high requirements on design, construction, and construction site management.
Professional technicians are required to participate.
|The initial investment of ground source heat pump is relatively high:
The initial investment of a small household ground source heat pump system is more than 100,000 yuan.
Large commercial ground source heat pumps are more expensive.
