GMV5E DC INVERTER VRF UNITS SERVICE MANUAL
Used for outdoor heat exchange.
Strengthens heat exchanging.
Used for defrosting detection.
Controls refrigerant adjustment in heating mode.
Controls refrigerant flow direction.
Controls the degree of subcooling of tube refrigerant when the system is running in
cooling mode, and reduces the capacity loss on pipes.
Controls the degree of subcooling of tube.
Detects tube temperature.
Detects the inlet temperature of gas-liquid separator to prevent the system from
running when the refrigerant flows back to the compressor.
Detects gas temperature of subcooler.
Detects system low pressure to avoid extra-low operating pressure.
Separate gas and liquid to prevent the system from running when the refrigerant
flows back to the compressor.
Detects internal status of gas-liquid separator to further control the compressor
suction performance.
Used for oil equalizing control among modules.
Used for oil equalizing control among modules and avoid reverse flow of oil.
Avoids over-high pressure caused by pipeline blind spot.
Used for oil equalizing control among modules.
Prevents impurities from entering components and parts.
Supports flow regulating and pressure reduction.
Stop valve, closed when the unit is delivered from the factory and will be opened
after installation.
Stop valve, closed when the unit is delivered from the factory and will be opened
after installation.
Detects the low pressure value or charges refrigerant during system running.
Stop valve, closed when the unit is delivered from the factory and will be opened
after installation.
Checks the quality of refrigerating machine oil of compressor during maintenance.
Avoid over-high pressure caused by pipeline blind spot.
Avoids extra-high or low operating pressure.
Ensures success startup of compressor.
