Title: Refrigerating device
Inventor: YABU TOMOHIRO
IPC: F25B13/00
Filed: 2000-01-13
Abstract: PROBLEM TO BE SOLVED: To increase the amount of an injection gas by providing a heating means in a refrigerant circuit, which supplies refrigerant of medium pressure to a compressor and increases enthalpy of the medium pressure refrigerant. SOLUTION: An injection mechanism for supplying refrigerant of medium pressure to a compressor 1, consists of a gas/liquid separator 6 and an injection path 11. In the injection mechanism, an electric heater 5 is located at an entrance side from which the medium pressure refrigerant enters into the gas/ liquid separator 6. In conducting injection, an iron core of the electric heater 5 is heated up to a high temperature to transfer the heat to two-layer refrigerant of gas/liquid phases so that the enthalpy of the two-layer refrigerant of gas/ liquid phases is increased to a given point. In this way, sufficient heating capacity can be ensured with a small outdoor unit when the outside temperature is low.
