Изобретение относитс к области холодильной техники.This invention relates to the field of refrigeration.
Известны способы подачи масла в маслосборник холодильной машины, преимущественно турбокомпрессионной, работающей на хладагенте, раствор ющемс в масле, путем отбора смеси масла жидким хладагентом из испарител , отделени масла с его осущкой от хладагента и возврата осущенного масла в маслосборник.Methods are known for supplying oil to an oil pan of a refrigeration machine, preferably a turbo-compression, working on a refrigerant dissolving in oil, by taking an oil mixture with a liquid refrigerant from an evaporator, separating the oil with its drainage from the refrigerant and returning the dried oil to the oil sump.
Описываемый способ отличаетс от известных тем, что отбор смеси из испарител осуществл ют эжектированием ее теплыми парами хладагента высокого давлени , и отделение с осущкой ведут в процессе эжектировани теплотой перегрева паров высокого давлени .The described method differs from the known ones in that the selection of the mixture from the evaporator is carried out by ejecting it with warm vapors of a high-pressure refrigerant, and separation with drying is carried out in the process of ejection by the heat of superheating of high-pressure vapors.
Это позвол ет повысить экономичность.This makes it more economical.
На чертеже схематично представлена установка дл реализации описываемого способа.The drawing shows schematically an installation for implementing the described method.
Смесь масла с хладагентом засасываетс из испарител 1 по трубопроводу 2 в приемную камеру эжектора 3. Рабочим телом эжектора служат перегретые пары хладагента высокого давлени , отбираемые из конденсатора 4.The mixture of oil and refrigerant is sucked from the evaporator 1 through line 2 to the inlet chamber of the ejector 3. The working body of the ejector is superheated high-pressure refrigerant vapor taken from the condenser 4.
Осушку масла от жидкого хладагента ведут в процессе эжектпровани теплотой перегрева высокого давлени . Чистое масло сливаетс в маслосборник 5, откуда насосом 6 через охладитель 7 подаетс в редуктор 8 турбокомпрессора 9. Пары хладагента пз маслосборника отсасываютс по трубопроводу 10 в турбокомпрессор .Drying the oil from the liquid refrigerant is carried out in the process of ejection of heat by high-pressure superheat. The clean oil is drained into the oil sump 5, whereupon the pump 6 through the cooler 7 is fed to the gearbox 8 of the turbocharger 9. The refrigerant pairs F3 of the sump is sucked off via line 10 to the turbocharger.
