Gas powered VRV / VRF systems. Where the amount of electrical supply is limited and a gas supply is available, gas powered VRF systems can be used. The gas powered VRF system uses a gas powered internal combustion engine in place of the electric compressors in the standard systems.
Refrigerant flow control is the key to many advantages as well as the. major technical challenge of VRF systems. Note the term VRF systems should not be confused with the centralized VAV (variable. air volume) systems, which work by varying the air flow to the conditioned space based. on variation in room loads.
