とにある。(Problem to be solved by the invention 1) In screw-type refrigerated soffit units equipped with a cylindrical horizontal oil separator, a forced lubrication system using an oil pump in the compression region is often adopted. The purpose of the invention is to prevent oil from flowing into the rotor due to its own weight while the compressor is stopped and becoming stagnant in a differential pressure lubrication system that eliminates an oil pump, resulting in poor lubrication and oil swell caused by foaming during startup. It is in.

憧ユニットの９１１１１ｆｉ図を示す。(Means for solving the problem) The above purpose is to prevent the oil from flowing into the rotor part due to its own weight while the pressure a-pressure machine is stopped. Considering this, the lower surface of the body of the oil separator is placed at a position lower than the position of the lower surface of the screw rotor. By arranging the upstream NO, it is possible to prevent oil from flowing into the screw rotor section due to its own weight and staying there when the compressor is stopped. 91111fi diagram of one screw type refrigeration unit is shown.
