Central AC systems are known for their energy efficiency, ease of temperature control, and ability to handle high cooling loads, making them suitable for larger commercial spaces.

Air-to-water heat pumps work by circulating heated water through radiators or underfloor heating systems in a home. Unlike mini-splits, which use refrigerant, these systems transfer heat from the outside air to water that circulates within the building.

Inverter technology has revolutionised the air conditioning industry and the inverter heat pump is one example of this. This air conditioning system uses a renewable energy source such as outside air to provide heating or cooling in a given space.

On April 17, 2024, OUTES officially presented a new frequency conversion heat pump at the Guangzhou International Trade Fair and received the "CERTIFICATE FOR FIELD VERIFICATION OF SEVERE NATURAL ENVIRONMENT" from China Electric Research CVC Weikai.
