PURPOSE:To stabilize the amount of oil by connecting between the bottoms of main compressor and an auxiliary compressor through an oil tank incorporating an electric heater and a check valve then gassifying the refrigerant dissolved in the oil in an oil tank to increase the gas pressure and flowing the oil to the auxiliary compressor. CONSTITUTION:The bottoms of main compressor 1 and an auxiliary compressor 2 are connected through a check valve 10, an oil tank 8 incorporating an electric heater 9 and a check valve 11. When the oil level in the main compressor 1 rises, an oil level sensor 12 will detect the oil level to supply the current to the electric heater 9 with predetermined period through a controller 13 thus to heat it. Consequently the refrigerant dissolved in the oil in an oil tank 8 is gassified to increase the pressure in the oil tank 8, thereby the pressure in the oil tank 8 will become higher than the pressure in the auxiliary compressor 2 and the oil in the tank 8 will flow through a check valve 11 into the auxiliary compressor 2 to obtain the oil amount reliably and stably resulting in the prevention of the burning of the auxiliary compressor 2. |
