The VRF/VRV (Variable Refrigerant Flow/Volume) air conditioning system is a one-to-many type central air conditioning system. This system is consists of 1 outdoor unit and 2 or more indoor units. The outdoor unit is for air-cooled heat exchange, and the indoor units adopt the direct evaporative heat exchange.
The VRF air conditioning system uses refrigerant as the conveying medium. The outdoor unit is composed of a heat exchanger, a compressor and other refrigeration accessories. The indoor unit is composed of a direct evaporative heat exchanger and a fan. One outdoor unit can deliver refrigerant liquid to several indoor units through pipes. By controlling the refrigerant circulation volume of the compressor and the refrigerant flow rate entering the indoor heat exchangers, the indoor cooling and heating load requirements can be timely met.
1. The VRV central air conditioner has a warm and comfortable air output, and the cooling (heat) is fast and strong;
2. The indoor unit is centrally managed, and one indoor unit can be started to run alone, or multiple indoor units can be started at the same time. It is more energy-saving.
3. VRF air conditioning system has a long service life and a very low unit failure rate. It is basically self-adjustment and diagnosis, no special maintenance is required, and the outdoor unit service life is as long as 30 years, which greatly saves maintenance costs.
