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.
All systems use R22 refrigerant. A HVAC gauges manifold shows pressure and temperature for both low and high pressure lines as seen at the compressor. The low pressure side is the larger of the 2 pipes coming out of or going into the outside compressor unit. The high pressure side is the small diameter line.
