What is the difference between air source heat pump and ground source heat pump?

With the popularity of coal-to-electricity conversion, heat pumps have gradually entered people's field of vision, but heat pumps are divided into ground source heat pumps and air source heat pumps. What is the difference between the two?

What is the difference between air source heat pump and ground source heat pump?
Air source heat pump: Simply put, air source heat pump uses a small amount of electricity to process outdoor air and deliver the comfortable temperature that meets our needs indoors. In this process, the air source heat pump consumes electricity and works twice, that is, to make the outdoor air temperature reach the required temperature, heating or cooling, which works on outdoor air, and the other is to transport cold and hot energy to the room, which is work on transportation. Air source heat pumps are affected by external natural factors. When the outdoor ambient temperature is very high, it is difficult to discharge indoor hot air, and the cooling effect in the room is poor. When the outdoor temperature is very low in winter, there will be frost when heating. Therefore, natural factors have a great impact on air source heat pumps.
Ground source heat pump: Ground source heat pump uses renewable energy, consumes a small amount of electricity through underground soil, converts it with the energy contained in the soil, and transports it to the room through the heat exchanger and carrier, which plays a role in heating in winter. In summer, the indoor heat is transmitted to the underground through the unit to play a cooling role. In this process, the ground source heat pump only works on transportation, which is why ground source heat pump air conditioners are more energy-efficient than air source heat pump air conditioners. Compared with air source heat pumps, it can save 40-60% of energy. The ground source heat pump air conditioning system works underground and is completely unconstrained by external natural conditions. It also runs stably, has multiple uses, and is low-carbon and environmentally friendly. The ground source heat pump system was first vigorously promoted by European and American countries to save energy, protect the environment, and optimize the environment. Later, in my country, this technical project also received great attention and strong support. The energy-saving effect of ground source heat pumps is still obvious, and it is worth being a good choice.
