Description
(54) СПОСОБ РАБОТЫ ПАРОЭЖЕКТОРНОЙ ХОЛОДИЛЬНОЙ МАШИНЫ Изобретение относитс к холодильной технике, а точнее к способам работы пароэжекторной холодильной машины. Известны способы работы пароэжек- торной холодильной машины, путем нагрева жидкого хладагента с получением паров высокого давлени , эжектировани ими паров : хладагента низкого давлени , конденсации образующейс смеси при промежуточном давлении и разделени полученной жидкости на два потока, первый из Которых направл ют на проведение холодильного цикла, а второй - на нагрев дл получени паров высокого давлени Недостатком известных способов вл етс их мала экономичность вслерьствие недостаточного переохлаждени потока жидкого хладагент, направл емого на проведение холодильного цикла. Цель изобретени - повышение экономичности . Указанна цель достигаетс тем, что первый поток жиокого хладагента, напра л емый на проведение холодильного цикла, предварительно охлаждают, преимущес венно водой, до температуры, соответствующей заданной холодопроизводитепьности машины. На чертеже представлена схема паро .эжекторной машины дл осуществлени способа. Машина содержит котел 1 дл нагрева жидкого хладагента с получением паров высокого давлени , эжектор 2, которым отсасывают пары хладагента низкого давлени из испарител 3, конденсатор 3 дл снижени образующейс смеси при промежуточном давлении, насос 5, подающий поток жидкого хладагента в котел I, пе- реохладитель 6 дл охлаждени потока жидкого хладагента , направл емого через дроссельный вентиль 7 в испаритель 3, температурный датчик 8, установленный на линии выхода хладоносител из испарител 3, исполнительный механизм 9, воздействующий на вентиль 1О, подающий воoiy в переохладитель 6.(54) METHOD OF WORK OF A STEEL-JET REFRIGERATING MACHINE The invention relates to refrigeration, and more specifically to methods of operating a steam-jet cooling machine. There are known methods for operating a steam-jet chiller by heating a liquid refrigerant to produce high-pressure vapors, ejecting vapor: a low-pressure refrigerant, condensing the resulting mixture at an intermediate pressure, and dividing the resulting liquid into two streams, the first of which are directed to the refrigeration cycle. and the second is for heating to produce high-pressure vapor. A disadvantage of the known methods is their low efficiency because of the lack of supercooling of the liquid stream. of refrigerant, steerable to carry out a cooling cycle. The purpose of the invention is to increase efficiency. This goal is achieved by the fact that the first flow of the coolant refrigerant directed to the refrigeration cycle is pre-cooled, predominantly with water, to a temperature corresponding to the specified cooling capacity of the machine. The drawing shows a diagram of a steam ejector machine for carrying out the method. The machine contains a boiler 1 for heating the liquid refrigerant to produce high-pressure vapors, an ejector 2 that sucks the low-pressure refrigerant vapor from the evaporator 3, a condenser 3 to reduce the resulting mixture at an intermediate pressure, a pump 5, a supply of liquid refrigerant to the boiler I, re-cooler 6 for cooling the liquid coolant flow directed through the throttle valve 7 to the evaporator 3, the temperature sensor 8 installed on the coolant outlet line of the evaporator 3, the actuator 9 acting to valve 1O, feeding air to sub-cooler 6.
