Description
чен. Насос 8 подает жидкий холодильный агент из ресивера 3 к испарителю 9. От испарител 9 пары с неиспарившейс жидкостью возвращаютс в ресивер 3, в котором происходит отделение пара от жидкости. Пар отсасываетс компрессором 2, сжимаетс в нем до давлени конденсации и поступает в конденсатор 1. Из коднесатора 1 жидкий холодильный агент подают в ресивер 3. Таким образом в ресивере 3 происходит посто нное накопление масла.chen The pump 8 delivers the liquid refrigerant from the receiver 3 to the evaporator 9. From the evaporator 9, the vapors with non-evaporated liquid are returned to the receiver 3, in which the vapor is separated from the liquid. Steam is sucked off by compressor 2, compressed in it before condensation pressure, and enters condenser 1. Liquid cooling agent is supplied from cod-1 to the receiver 3. In this way, constant accumulation of oil occurs in receiver 3.
В это же врем в ресивере 4 происходи выпаривание холодильного агента из маслофреоновой смеси и подогрев, масла обогревателем 6. После того, как произошло полное отделение маспа от холодильного агента , а его температура доведена до температуры в картере компрессора 2, оно возвращаетс в картер компрессора. Удалив масло из ресивера 4, переключением вентил 5 измен ют режимы ресиверов и 4.At the same time, in the receiver 4, evaporation of the refrigerant from the oil freon mixture and heating of the oil by the heater 6 occur. After the masp has completely separated from the refrigerant and its temperature has reached the temperature in the compressor crankcase 2, it returns to the compressor crankcase. After removing the oil from the receiver 4, switching the valve 5 changes the modes of the receivers and 4.
Така холодильна насосно-циркул ционна система охлаждени пригодна дл всех холодильных агентов, но особенно она эффективна дл агентов, имеющих ограниченную растворимость с маслом, например, как фреон - 22,Such a refrigeration pump-circulation cooling system is suitable for all refrigerants, but it is especially effective for agents that have limited solubility with oil, for example, freon - 22,
