Title: Cooling method for enclosed motor compressor
Inventor: INOUE WAHEI
IPC: F04B39/06
Filed: 1987-12-24
Abstract: PURPOSE:To prevent abnormal temperature rise of a rotor by supplying refrigerant gas around the rotor of a motor when the temperature thereof increases. CONSTITUTION:When the refrigerant gas pressure in the housing of a compressor 2 lowers due to increase of cooling load, an output is fed from a refrigerant control load power sensor 15 or a rotor temperature sensor 31 to a regulator 33, then the refrigerant is fed through a control valve 34 into a motor 1 and held at a regulated pressure. The refrigerant gas passes through bearing sections and carries heat produced from a rotor 11 into the housing of compressor. Consequently, refrigerant gas surrounding the rotor 11 is agitated through the rotor and radiates heat through the stator core and the stator frame to the outside through convection of gas.
