It is a refrigerant-based air conditioning system. Variable-frequency multi-split systems (also known as VRV) differ significantly from ordinary household air conditioners in terms of their structure and control methods. It uses a refrigerant as the transmission medium and consists of an outdoor unit and multiple indoor units. The outdoor unit includes an outdoor heat exchanger, a compressor, and other cooling accessories; its function is to transport refrigerant liquid to the indoor unit through pipes. The indoor unit, also known as the terminal device, consists of a direct-evaporation heat exchanger and a fan. By controlling the amount of refrigerant circulating in the compressor and the flow rate of refrigerant entering the heat exchangers of each indoor unit, the indoor cooling and heating loads are appropriately managed to achieve temperature regulation of the air. It can automatically adjust the capacity of the system based on the size of the indoor air conditioning load, thus offering advantages such as energy savings, comfort, and smooth operation. Moreover, each room can be adjusted independently to meet the different air conditioning requirements of various rooms. However, its system control is complex, and the investment is relatively high. Such systems make it difficult to introduce fresh air, cannot regulate air quality, and are also challenging to install and maintain. In a sealed room, comfort levels are lower, and installation and maintenance are also more difficult.

The full name of the VRV air conditioning system is Varied Refrigerant Volume, abbreviated as VRV. It is a refrigerant-based air conditioning system that uses refrigerant as the medium for heat transfer. The outdoor unit consists of an outdoor heat exchanger, a compressor, and other cooling components, while the terminal unit is an indoor unit made up of a direct-evaporation heat exchanger and a fan. An outdoor unit can deliver refrigerant liquid to several indoor units through pipes. By controlling the amount of refrigerant circulating in the compressor and the flow rate of refrigerant to each heat exchanger inside the room, it is possible to meet the indoor cooling and heating demands at the appropriate time. The VRV system offers many advantages such as energy efficiency, comfort, and stable operation; moreover, each room can be adjusted independently to meet the varying air-conditioning needs of different rooms. However, this system is complex to control, with very high requirements regarding the material of the pipes, manufacturing processes, on-site welding, etc., and its initial investment is relatively high.

The full name of the VRV air conditioning system is Variable Refrigerant Flow system. In terms of system structure, it is similar to split-air-conditioning units, with one outdoor unit corresponding to a set of indoor units (typically up to 16 units). In terms of control technology, variable-frequency control is employed; the speed of the scroll compressors in the outdoor units is adjusted based on the number of indoor units that are in operation, thereby controlling the flow rate of the refrigerant.
