HVAC VRV (Variable Refrigerant Volume) is a type of air conditioning system that uses variable refrigerant flow technology to provide cooling and heating to multiple zones in a building. This type of system is often used in commercial and industrial buildings, as it is more efficient than traditional air conditioning systems. It works by using a single outdoor condensing unit to supply refrigerant to multiple indoor fan coil units. Each fan coil unit is connected to its own thermostat, allowing the user to control the temperature in each zone separately. The system is also able to adjust the amount of refrigerant that is sent to each fan coil unit, allowing it to be more efficient and reduce energy costs. The VRV system is also able to reduce the amount of noise that is produced by the system, making it a great choice for businesses that need to maintain a quiet environment.
