An ejector refrigerating machine includes sequential processes of evaporation of liquid at high pressure, expansion of high pressure vapor formed, ejection of low pressure vapor, increase of pressure of total vapor to intermediate pressure, vapor condensation at intermediate pressure, liquid overcooling at intermediate pressure with its following expansion to low pressure, liquid evaporation at low pressure with heat supply to it from external heat carrier, low pressure vapor is ejected in saturated state, that for it is previously separated from vapor-liquid low pressure mixture formed as result of not complete evaporation of liquid at low pressure with heat supply from external heat carrier to it, and liquid with intermediate pressure is overcooled with discharge of heat from it for evaporation of low pressure liquid separated from vapor-liquid low pressure mixture. The invention provides increase of coefficients of ejection and increases power efficiency of the refrigerating machine. |
