Abstract:
A vapor compression refrigeration system that transfers heat from a low temperature side to a high temperature side, the vapor compression refrigeration system comprising:a compressor that draws and compresses refrigerant; a high pressure side heat exchanger that releases heat from high pressure refrigerant discharged from the compressor; a low pressure side heat exchanger that vaporizes low pressure refrigerant; an ejector that increases intake pressure of the compressor and includes: a nozzle arrangement that depressurizes and expands high pressure refrigerant supplied from the high pressure side heat exchanger; and a pressurizer arrangement that draws vapor phase refrigerant, which is vaporized in the low pressure side heat exchanger, through use of high speed refrigerant flow discharged from the nozzle arrangement and converts expansion energy of the refrigerant discharged from the nozzle arrangement into pressure energy; and a gas-liquid separating means for separating the refrigerant discharged from the ejector into vapor phase refrigerant and liquid phase refrigerant, wherein: the gas-liquid separating means has a vapor phase refrigerant outlet for outputting the vapor phase refrigerant and a liquid phase refrigerant outlet for outputting the liquid phase refrigerant, and the vapor phase refrigerant outlet and the liquid phase refrigerant outlet of the gas-liquid separating means are connected to a refrigerant inlet of the compressor and a refrigerant inlet of the low pressure side heat exchanger, respectively; and at least the gas-liquid separating means and the low pressure side heat exchanger are arranged in a common casing.
