What is the definition of a VRF HVAC system? VRF stands for Variable Refrigerant Flow and is a type of HVAC (Heating, Ventilation, and Air Conditioning) system that uses variable speed compressors to adjust the flow of refrigerant to meet the cooling and heating needs of a space. This type of HVAC system is typically used in larger commercial buildings, such as office buildings or hotels, as it provides more efficient and flexible temperature control.
The system works by using an outdoor unit with multiple compressors that are connected to multiple indoor units. Each compressor is regulated to adjust the flow of refrigerant to each individual unit. This allows for a greater level of control over the temperature in each room. It also allows for different temperature and humidity settings for different parts of the building, such as a lobby area or a meeting room.
The main advantage of a VRF HVAC system is that it can save energy
