A Variable Refrigerant Flow (VRF) System is a type of air conditioning system that uses refrigerant as a cooling and heating medium. It is a form of central air conditioning system that can provide individual temperature control of several rooms, each with its own thermostat. A VRF works by transferring cold or hot liquid refrigerant through pipes to individual indoor units where it is then converted into a gas. The gas is then used to cool or heat each room, depending on the thermostat setting. The refrigerant is circulated throughout the system and then returned to the condenser where the cycle is repeated. The VRF system is different from traditional air conditioning systems in that it has a variable refrigerant flow and temperature control, allowing multiple indoor units to be connected to a single outdoor unit. This allows for more efficient energy consumption and individual room temperature control. The VRF system is also more environmentally friendly due to its use of environmentally friendly refrigerants and its ability to adjust its cooling
