Abstract

Use: in refrigeration units for cooling liquids in the food, chemical, and pharmacological industries. SUMMARY OF THE INVENTION: The heat transfer surface area of the evaporator is changed by connecting or disconnecting the distribution tubes of the tank, which are the evaporator of the refrigeration unit with a change in the level (amount of liquid) in the tank. The evaporator tubes are connected to the refrigerant supply line from bottom to top by moving the spool along the dispensing manifold. The spool moves due to vacuum in line with an electromagnetic valve electrically connected to the level controller. 3 ill. SB with

Description

The present invention relates to refrigeration, in particular to refrigeration units for cooling liquids and can be used in food, chemical, pharmacological and related industries.

The purpose of the invention is to increase efficiency by enhancing heat transfer and preventing freezing of the refrigerated product on the walls of the container.

In FIG. 1 shows a diagram from which the principle of operation of a cooling system is understood; figure 2 is a General view of the capacity of the evaporator; Fig. 3 shows a section through the collectors of the evaporator.

The liquid cooling system includes a compressor 1. a condenser 2, a vertical container for the cooled liquid 3, containing an evaporator, including a distribution manifold 4, a collecting manifold 4, distribution tubes 6, an adjusting spool 7. installed in the distribution manifold 4. On the refrigerant supply pipe 13 to the distribution the manifold 4 is equipped with a thermostatic control valve 8. On the pipeline 14 connecting the dispensing manifold 4 to the input of the compressor 1, an electromagnetic valve 9 is installed, connected to the regulator liquid level 10 with the sensing element 11. In the distribution manifold 4 holes 12 are made.

The system operates as follows.

The liquid that needs to be cooled and then stored in a cooled state is placed in a container 3. The sensor element 11 of the level gauge 10 converts the movement and / or other physical change corresponding to a change in the liquid level into voltage and then into a unified direct current signal , which controls the opening of the solenoid valve 9. When opening the solenoid valve, the cavity above the adjustment

by the lottery 7 is connected to the suction side of the compressor 1, the adjusting spool 7 rises in direct proportion to the liquid level in the container 3, opening the holes 12 in the dispensing manifold 4, in which distribution pipes 6 are connected which are below the liquid level in the container. The refrigerant entering the tubes 6 takes away the heat going to its boil only from the process fluid, and the evaporator tubes 6 above the liquid level are not involved in the cooling process, as a result of which there is no freezing of ice on the inner walls of the tank 3. The evaporated refrigerant enters from the tubes 6 to the collecting manifold 5, from where it is sucked off by the compressor 1. In the compressor 1, the gaseous refrigerant is compressed and pumped into the condenser 2, where it goes into the liquid phase and is sent back to the evaporator.

This liquid cooling system allows the container-evaporator to be manufactured in the form of a vertical vessel, which will lead to a 3-5-fold saving in production space, as well as to increase the thermodynamic efficiency of the evaporator, improve the performance of the refrigeration unit and exclude it from the circuit
