TECHNICAL FIELD The present invention relates to a brine cooler.

2. Description of the Related Art The conventional apparatus is "freezing" 1994 Vol.
69, p.54 of No. 804, the refrigerant cycle is independent in the brine cooler unit equipped with two compressors, but the brine cycle is when one compressor is installed. The same cycle applies when multiple units are mounted. Therefore, when there are two types of brine to be used depending on the purpose, two brine coolers are required. Further, even when there are two types of brine inlet / outlet temperatures to be used, it is necessary to mount two brine coolers. For this reason, not only the cost is greatly increased, but also the device becomes complicated and large in size as a brine cooler unit.

FIG. 4 shows an example of a refrigeration cycle system using two screw compressors, and FIG. 5 shows a plan view of a brine cooler in that case.

Since the conventional brine cooler 7 does not have the trunk side partition 10, only one type of brine can be used. Also, the brine inlet / outlet temperature is limited to a design under fixed usage conditions.

[0005]

A brine cooler unit equipped with one or a plurality of screw compressors in the prior art is a brine cooler having the same number of refrigerant inlets and outlets as the compressor and a brine inlet and outlet common to the compressors. To form a refrigeration cycle. Since the brine side of this brine cooler has one cycle, the freezing temperature,
It is impossible to use brine with different physical properties such as specific gravity, geothermal heat, viscosity and thermal conductivity at the same time.

Further, since the brine cooler is designed and manufactured only by the physical properties of one type of brine and the specification conditions of one type of brine inlet / outlet temperature, it cannot be used at several types of brine inlet / outlet temperatures.

An object of the present invention is to use a brine cooler unit equipped with a single brine cooler with brines having different physical properties, and to enable the brine inlet and outlet temperatures to be different temperatures.

[0008]

In order to achieve the above object, the present invention provides a plurality of refrigerant inlet / outlets in a brine cooler unit equipped with one or more screw compressors and one brine cooler. A plurality of brine inlets and outlets are provided, and partition plates are provided on the refrigerant side and the brine side.

In a brine cooler unit equipped with one or more screw compressors, a plurality of refrigerant inlets and outlets of a brine cooler are provided to form a refrigerant cycle, and a plurality of brine inlets and outlets of the brine cooler are provided. By installing a partition plate for each refrigerant cycle on the side of the brine cooler, it is possible to make the cycle on the brine side independent, and to use different brine and brine inlet / outlet temperature at the same time in one brine cooler. Is possible.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS One embodiment of the present invention will now be described with reference to FIGS.
2 and 3 show.

FIG. 1 shows a brine cooler unit equipped with two screw compressors as an example of a refrigeration cycle system diagram using a plurality of compressors.

The refrigerant is compressed into high-pressure and high-temperature gas by the screw compressor 1, and separated by the oil separator 2 into refrigerant gas and refrigerating machine oil. The refrigerant gas becomes a condensed liquid in the condenser 3 and is sent to the supercooler 4 to be supercooled, and the liquid refrigerant is passed through the main liquid solenoid valve 5 and the main liquid expansion valve 6 and the refrigerant inlet 1 of the brine cooler 7
Enter from 1 and cool the brine. At this time, the refrigerant passes through the inside of the cooling pipe 14, and the brine flows around the cooling pipe so as to face each other to perform heat exchange. The refrigerant that has cooled the brine evaporates, is discharged from the refrigerant outlet 12, and is sucked into the screw compressor 1. The refrigerant entering the brine cooler can be sent to the desired brine side by switching the refrigerant inlet 11 by operating the blocking valve.

FIG. 2 is a plan view of the brine cooler of the present invention, and FIG. 3 is a front view and a sectional view of the brine cooler.

The refrigerant gas entering from the refrigerant inlet 11 of the brine cooler 7 passes through the inside of the cooling pipe 14 by the refrigerant side partition plate 13 of the side cover portion and is discharged from the refrigerant outlet 12.
At that time, the brine on the barrel side enters the barrel through the brine inlet 8 and is cooled by exchanging heat with the refrigerant in the cooling pipe 14 while meandering. A partition plate 10 is provided on the body side to
This prevents the brines coming in through the brine inlets 8 at some locations from coming into contact with each other.

Further, the number and arrangement of the cooling pipes 14 can be independently determined depending on the physical properties of the brine and the brine inlet / outlet temperature specifications.

[0016]

According to the present invention, a single brine cooler unit can be used even when the use is different for food processing and industrial use and the physical properties of the brine used are different.

Further, the brine inlet / outlet temperature can be freely changed for each brine, and the cost can be reduced and the device can be downsized.
