Indoor Unit AirTS-530N / AirTS-670N

The VRF air conditioners, also known as "one-to-many," is a type of system
where one outdoor unit is connected to several indoor units. Each indoor unit
can operate independently or be controlled together. The system has an outdoor
unit connected by pipes to indoor units that have components like outdoor heat
exchangers, compressors, and other parts. The indoor units consist of fans and
direct cooling elements. Using the pipes, the outdoor unit can supply cooling
liquid to many indoor units. It controls the compressor's cooling fluid
circulation and the flow into various indoor heat exchangers to meet the indoor
cooling and heating needs.
The system's working principle is simple: the indoor temperature sensor
controls the valve on the indoor unit's cooling pipe. By adjusting the
pressure, the system can control the outdoor unit's compressor speed or change
its operating mode to adjust the cooling capacity according to the load.
