What is VRF System ?

Variable Refrigerant Flow
The Variable Refrigerant Flow System has the ability to control the
amount of refrigerant flowing through the system
Simply, each FCU/AHU unit receives only the required amount of
refrigerant in order to meet the cooling load of the conditioned space
The Inverter Unit will Gradually Increases or Decreases its Capacity
based on the load by increasing or decreasing the rotation speed of
the motor.
World Best COP Tech.

What is LG Multi V?
Owing to VRF Technology, Multi V is the Brand Name of LG.

Multi V is the LG VRF system: Compared to the Common On-Off Controlled Compressor,

the Inverter Controlled Compressor is able to run the proper
revolution (Hz) in order to provide the best efficiency (power
Consumption), Exceptional dehumidification& Temp Control.
