A Variable Refrigerant Flow Heat Pump (VRFHP) is an energy-efficient heating and cooling system used in commercial buildings. It works by using a refrigerant to move heat from one location to another, and can be used for both heating and cooling. VRFHP systems are designed to respond quickly to changing temperatures and can be easily customized to meet specific needs or requirements. The technology is also quieter than traditional HVAC systems, making it an ideal solution for offices and other commercial spaces.
