VRF/VRV

VRF (Variable Refrigerant Flow) and VRV (Variable Refrigerant Volume) systems are both types of HVAC systems that offer energy-efficient heating and cooling solutions for buildings. They use refrigerant as the cooling/heating medium and can vary the flow of refrigerant to different indoor units based on the heating or cooling requirements of each zone. The main difference between VRF and VRV lies in the trademark names and manufacturers. VRF is a generic term used to describe systems that control the flow of refrigerant based on demand, while VRV is a specific trademarked term by Daikin for their VRF systems. These systems offer individualized temperature control, zoning capabilities, and can be more energy-efficient compared to traditional HVAC systems. VRF/VRV systems are popular in commercial buildings and some residential applications due to their flexibility and energy-saving features.
