Abstract

The invention relates to refrigeration equipment, namely to refrigerated vehicles for the transport and temporary storage of NII perishable goods. The aim of the invention is to ensure uniform cooling and stable temperature maintenance. The refrigerant from the tank 3 enters the heat exchanger 4, where it evaporates, heats n through the nozzle (C) 11 exits at an accelerating speed into the ejector (E) 9, as a result of which a reduced pressure zone is created. Under the action of the ejection effect, the air from the camera body 1 also enters the O 9, where, depending on the temperature, the temperature is equal. The fluid is replaced with a gaseous. cool-ai enTOM, nocTynaionuiM through C 11, or with a liquid refrigerant entering through conduit 12, n is sent to the cyclone (C) 10. At C 10, cooled air escapes and the fresh air enters the body 1 camera. The sequential placement of the cooled air E 9 and C 10 on the path of movement allows uniformly cooling the air in the chamber and stably maintain the temperature throughout all its volume. 1 il.

Description

I.i) shaving refers to refrigeration equipment, namely to refrigerated vehicles for non-carriage and temporary storage of skoronort and cargo.

The aim of the invention is to provide uniform cooling and stable temperature maintenance.

The drawing shows a chamber for cooling the perishable cargo.

The chamber for cooling the skoroporta and; their cargo contains a heat-insulated body 1, connected by pipeline 2 em. Bone 3 with a liquid refrigerant and heat exchanger 4, located in the upper part of the chamber's cornea box 5, having nozzles 6 and suction pipe 7 s. 1 m hole 8. Inside the pipe 7, an ejector 9 is installed, connected in series with the cyclone 10, and the outlet pipe of the ejector is connected to the inlet pipe of the cyclone, and the output pipe of the cyclone 10 is connected to the duct 5. In the inside of the ejector 9, sequentially meiheny nozzle P, which is located at the open end of the heat exchanger 4, the pipeline 12 for supplying liquid refrigerant with a thermostatic valve 13 and the thermal sensor 14. Cyclone 10 has a drain pipe 15 with a hydraulic seal 16.

The device works as follows.

Under the action of gas overpressure from the tank 3 through the pipeline 2, the refrigerant enters the heat exchanger 4, where it evaporates, heats up in a gaseous state and through coH, io 11 goes out at great speed into the ejector 9, as a result of which a reduced zone is created in the ejector 9 davien Under the effect of the ejection-1P1I effect, the air from the inner space of the chamber's cornea 1 through the passage opening 8 of the suction pipe | its pipe 7 enters the ejector 9, in which li is mixed depending on the temperature conditions

with gaseous refrigerant flowing through the nozzle 11, or with liquid refrigerant flowing through pipeline 12, and sent to the cyclone 10. The control of the flow of liquid refrigerant through pipeline 12 is carried out using a thermal sensor 14 and a thermostatic valve 13. In a cyclone 10 from cooled air moisture is precipitated as a solid phase and precipitates in the lower part of the cyclone 10, where it melts and is discharged from the chamber through the drain pipe 15 and the hydraulic lock 16. The dried air from the cyclone 10 enters the duct 5, is cooled by the heat exchanger 4 and through nozzles 6 it is evenly distributed over the internal volume of the heat insulated body 1 of the chamber.

Sequential placement in the path of movement of the cooled air between the passage opening 8 and the nozzles 6 of the ejector 9 and the cyclone 10 allows the air in the chamber to be uniformly cooled and the temperature to be maintained steadily throughout its entire volume.
