Abstract

PURPOSE:To increase an injection amount of refregerant gas for improved capacity by forming several injection holes of a proper diameter throughout a range of a certain angle at which an injection may be suitably performed. CONSTITUTION:Because successive several injection holes 26 are fomed, an injection may be satisfactorily performed up to a position where an interior pressure of a housing gets equal to an injection pressure immediately after almost suction gas is trapped. Injected refrigerant gas is compressed and discharged along with another refrigerant gas which is sucked from a main circuit. The discharged and compressed refrigerant gas is heat-exchanged with heat-exchange fluid such as air or water in a condenser 2 and condensed into liquid. On the other hand, the heat-exchange fluid is used as a heating source for heating or radiates heat into atmosphere for cooling.
