What is the difference between air source heat pumps and air conditioners?

There are several differences between air source heat pumps and air conditioners. Nuentai summarizes them as follows:

First, different operating principles

The main functions of central air conditioners It is refrigeration, which uses power-driven compression to work, converting low temperature into high temperature for heat dissipation and refrigeration. Therefore, the main focus of air conditioners is refrigeration, supplemented by heating. When heating, the air conditioner also needs to turn on electric heating. Auxiliary heating. This is not the case with air source heat pumps. They mainly use air energy and electric energy to convert low-temperature refrigerants into high-temperature media. Therefore, air source heat pumps focus on heating and can operate at any temperature without using electric heating. They also have the advantages Refrigeration function.

Second, the heating methods are different

Air source heat pumps are mainly used for hot water heating and supply equipment, while central air conditioners transport cold air to the indoor environment. At the same time, the air source heat pump will automatically stop working when heating reaches the specified temperature, while central air conditioners do not have this function. In addition, in terms of the way of converting heat, central air conditioners achieve temperature conduction through circulation, while air-energy heat pumps conduct temperature conduction through media, such as water.

Third, differences in usage areas

In terms of regional differences, due to the differences between north and south, central air conditioners are mainly used for summer cooling in the south, while air source heat pumps are used in the north. of heating. Since the south generally requires moderate temperatures, the opposite is true in the north. The lowest temperature in the north in winter may reach -30°. This requires very strict requirements for core components. At the same time, the supply of heat sources also needs to be more efficient and energy-saving. Therefore, according to the region situation, the demand for air source heat pumps in the north is more extensive. Central air conditioners are more used for cooling in the south, and the heating degree of air conditioners is inferior to that of air source heat pumps, so there are more choices of air source heat pumps in the north.
