Abstract

1380758 Refrigerating STAL REFRIGERATION AB 8 Dec 1972 [22 Dec 1971] 56685/72 Heading F4H In a compression-condensation refrigeration system, oil and refrigerant pass from the compressor 2 through a line 16 to an oil separator 3 from which the refrigerant flows to a condenser 5 and thence through a line 8 to an oil cooler 7 before return through a line 11 to an intake 10 in the compressor which is located at a point where the pressure substantially corresponds to the pressure of the refrigerant when it leaves the oil cooler. A regulating valve 9 in the line 8 controls flow of refrigerant to the cooler in response to the temperature of the refrigerant either on the outlet side of the cooler or the compressor as sensed by thermostats 17, 17<SP>1</SP>. A constant pressure valve 12 may be located in the line 11. As shown, a pump 13 passes the oil from a container 4 through the cooler to the compressor for lubrication purposes, the oil and refrigerant being maintained in separate paths (Fig. 5). Alternatively the oil and refrigerant are mixed together in the oil cooler to cool the oil, the vapourized refrigerant and oil returning separately to the compressor.

Указанна  цель достигаетс  тем, что охладитель масла выполнен смеси тельного типа и на линии св зи с дополнительным входом компрессора снабжен регул тором давлени . На чертеже схематично изображена предлагаема  система охлаждени .

A refrigeration oil system of a refrigeration compressor of a rotary type, containing an oil separator connected to the compressor’s discharge side and a condenser, an oil cooler connected at the inlet to the condenser through a pipe fitted with a thermal control valve, and to the lower cavity of the oil separator, and at the outlet connected to an additional Inlet of compressor 1. A disadvantage of this cooling system is the slowed down process of cooling the oil, which leads to an increase in the overall dimensions of the system. The purpose of the invention is to intensify the process of cooling the oil. This goal is achieved by the fact that the oil cooler is of the mixing type and is supplied with a pressure regulator on the communication line with the auxiliary input of the compressor. The drawing shows schematically the proposed cooling system. The cooling system of oil of a refrigeration compressor 1 of a rotary type contains an oil separator 2 connected to the discharge side of compressor 1, a condenser 3, an oil cooler: 4 connected at the inlet to the condenser 3 by means of a pipe 5 fitted with a thermal control valve 6, and to the lower cavity of the oil separator 2 through a pump 7, and the output is connected to the auxiliary input of the compressor 1 by a communication line 8, equipped with a pressure regulator 9. The oil cooler 4 is of a mixing type. The mixture of working medium and oil is sucked from the low pressure side by compressor 1, compressed and directed to oil separator 2, where the oil is separated. The separated medium enters the condenser 3, where it is condensed and the condensate formed through the pipe 5 enters the oil cooler 4. The oil from the lower cavity of the oil tallow 2 is pumped by pump 7 into

охладитель масла 4, где смешиваетс  с конденсатом рабочей среды, охлаждаетс  и образованна  смесь подаетс  к дополнительному входу в компрессор со стороны низкого давлени  по ли ии св зи 8.The oil cooler 4, where it mixes with the condensate of the working medium, is cooled and the formed mixture is supplied to the additional entrance to the compressor from the low pressure side of the connection 8.

Количество конденсата рабочей среды регулируетс  терморегулирующим вентилем 6, управл емого по температуре смеси рабочей среды с маслом.The amount of condensate of the working medium is regulated by a thermoregulatory valve 6 controlled by the temperature of the mixture of working medium with oil.

В качестве регулирующей температуры может служить температура смесиThe temperature of the mixture can serve as a regulating temperature.

Температура смеси на выходе из охладител  масла 4 контролируетс  с помощью регул тора давлени  9, измен ющего давление смеси и, соответственно , температуру.The temperature of the mixture at the outlet of the oil cooler 4 is controlled by means of a pressure regulator 9, which changes the pressure of the mixture and, accordingly, the temperature.

Выполнение охладител  масла смесительным и наличие регул тора давлени  на ЛИНИИ св зи охладител  масла с дополнительным входом компрессора , интенсифицирует процесс охлаждени  масла и уменьшает габариты системы в целом.The implementation of the oil cooler by mixing and the presence of a pressure regulator on the LINE of communication of the oil cooler with an additional compressor inlet intensifies the process of oil cooling and reduces the overall size of the system.
