Patent JP-2003028521-A (JP)
Title: Vapor compressive refrigerating machine
Inventor: SANUKI MASAMI
IPC: F04C29/00
Filed: 2001-07-16
Abstract: PROBLEM TO BE SOLVED: To prevent such a disadvantage that a cooling capacity surpasses the quantity of heat generated in a driving circuit and dew formation occurs in the circuit. SOLUTION: A cooling refrigerant passage 152a for cooling the driving circuit Ic, and a bypass refrigerant passage 152b which leads a refrigerant flowing out from an evaporator 500 to an intake port 113 without making it conduct heat exchange with the driving circuit Ic, are provided. Consequently, the refrigerant flowing out from the evaporator 500 can be prevented from flowing entirely through the cooling refrigerant passage 152a. Therefore, the cooling capacity in the passage 152a is prevented from surpassing the quantity of heat generated in the motor driving circuit Ic and the disadvantage that the dew formation occurs in the motor driving circuit Ic can be prevented.
