Abstract

PURPOSE: To obtain the maximum heating capacity constantly by mixing the high temperature oil discharged from a compressor with the low temperature oil conducted through an oil-cooler as adjusting their amounts for controlling the oil at a proper temperature to be supplied to the compressor.
CONSTITUTION: The oil separated from refrigerant by an oil-separator 2 is partly conducted to a mixing valve 12 via a bypass 11 as keeping its high temperature, and partly cooled by an oil-cooler 6 into a low temperature to be sent to the mixing valve 12. In the mixing valve 12, when low temperature oil 17 flows in from above, a wax thermostat 13 is contracted to close an upper valve 14, and a lower valve 15 is opened to introduce high temperature oil 18. When the high temperature oil flows in too much, the wax thermostat 13 is expanded to close the lower valve 15, and the upper valve 14 is rather opened. In this construction, the maximum heating capacity can be constantly obtained by controlling the oil at a proper temperature to be supplied to a compressor 1.
