Claims (1)

Patent claim Dryer - desuperheater, characterized by the fact that it consists of a horizontal dehumidifier tank / l /, the outside of which there is an axially mounted shell-tube subcooler / 2 / connected to the bottom from the side of the vapor inlet from the evaporator, and the outlet is the inside of the dehumidifier tank / l /, there is a ring-shaped demister / 3 / on the suction side of the compressor upstream of the vapor outlet, and the dryer tank / 1 / is connected from the bottom by at least one stub / 11 / to the space of the pipe, preferably heated by hot steam jackets -ΓUΓCwego oymika heat / 8 /, and the oil outlet from the heat exchanger / 8 / through the connector Il2l It is connected to the compressor crankcase. The subject of the invention is a dehumidifier-subcooler, especially used in phon cooling devices. There are freon dryers that also act as oil / freon separators, consisting of a horizontal liquid subcooler of the shape of ^ and ^ and ^ ru ^^ ka shell-and-UΓowegt, permanently connected at half height with a vertical oil separator in the shape of a tank. The vertical oil separator has a coil at the bottom to be heated with hot vapors, and protects the compressor against flooding with liquid medium, by positioning the suction pipe on the upper part of the oil separator. The disadvantage of this dryer is the incomplete separation of the liquid freon from the oil, which causes the liquid freon and with cold oil to flow into the compressor crankcase. At low compressor capacities, liquid freon accumulates in the lower part of the oil separator, the amount of which the heat supplied from the hose (the coil cannot evaporate it. The design of this type of dryer is very complex. The dehumidifier consists of a horizontal dehumidifier tank, on the outside of which there is a shell and tube subcooler, connected to the bottom on the side of the steam from the steam trap. vapor from the subcooler forms the air to the dryer reservoir. There is a ring-shaped deister before the steam flies from the dehumidifier tank through the nozzle to the suction side of the compressor. In addition, from the bottom, the desiccant tank is connected with the space of its own pipe, preferably heated by hot steam shell and tube heat exchangers, by means of one stub pipe. The oil outlet from the inter-pipe space oy of the heat meter is connected to the compressor crankcase. The dehumidifier according to the oyralazku has a rolled structure connected to the apparatus ^. The horizontal positioning of the dehumidifier tank and the use of demister rings effectively facilitate the drying of wet vapors. Connected to the lower part of the dryer: jacketcwt-] · Jn '' (heat exchanger for the evaporation of freon from the oil. Object of the invention An example of an embodiment is shown in Fig. 1, in which Fig. 1 shows a longitudinal section of a dryer, and Fig. 2 shows a section along line AA in Fig. shell subcooler 2. The outer side of the subcooler 2 is connected on one side by a chamber with a bottom having a nozzle 5 of steam from the steam tube, and o ^ ot is the front of the dryer tank 1. The space between the track and the subcooler 2 near its end It is connected with stub pipes 6, 7 through the tank 1 jacket to the liquid refrigerant system. Near the end of the tank 1 on the side of the parl 158 406 with the nozzle 5, the tank 1 has an outlet connection for vapor 4 to the compressor, where in front of the vapor outlet in the free space between the shell of the tank 1 and the external diameter of the subcooler 2 there are demister rings 3. The lower part of the dryer tank 1 is connected with the pipes 11 with the space between the pipes shell-ΓuιiCw, "egi heat measurement 8, and the chambers of the inner tube space are terminated with stub pipes 9, 10. Additionally, the heat exchanger tube space 8 has an oil drain connection 12 to the compressor crankcase.
