ABSTRACT:
A refrigerant piping system for a refrigeration machine includes an injection pipe connected at one end thereof with the suction port of a compressor and at the other end with the outlet port of a condenser. The injection pipe is provided with a solenoid valve for suppressing a coolant from flowing into the compressor during a heating operation of the machine. By closing the solenoid valve during the heating operation, the liquid coolant is prevented from flowing into the compressor through the injection pipe.
