Abstract
A refrigerant apparatus having a compressor, a condenser, a first expansion valve means, a gas-liquid separator, a second expansion valve means and an evaporator. The compressor has a plurality of cylinders one of which is connected with the gas phase of the gas-liquid separator in order to inject the gas coolant into the compressor, other cylinders of the compressor being connected to the evaporator in order to suck the coolant from the evaporator. Since the gas coolant within the gas-liquid separator is injected into the compressor, the cooling capacity of the coolant passing through the evaporator can be expanded so that the cooling capacity of the present invention is increased. Though the gas coolant within the gas-liquid separator which includes no lubricant is sucked toward the compressor, the compressor can be lubricated by the lubricant coolant effectively, because the same compressor sucks the coolant containing lubricant from the evaporator.
