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.
VRF (variable refrigerant flow) or VRV (variable refrigerant volume) comfort systems consist of multiple evaporators with variable capacity, connected to one central variable-capacity inverter-driven heat pump. These systems feature a heat-recovery mode that allows the transfer of energy from zone to zone with minimal compressor use.
