Description

Cooling system of kimchi refrigerator having plural evaporator

The present invention relates to a cooling system of a kimchi storage system having a plurality of evaporators for preventing the temperature change of another storage room that is not used when using only one storage room in a kimchi storage having two or more storage rooms.

Generally, a cooling cycle includes a compressor for making a refrigerant into a gas state of high temperature and high pressure, a condenser for forcibly liquefying and liquefying the high temperature and high pressure refrigerant sent from the compressor, an expansion valve for expanding the liquefied refrigerant, In the process of evaporating while passing through the expansion valve has a configuration consisting of an evaporator to absorb the heat of the ambient air to cool.

On the other hand, in such a cooling system, the evaporator which performs a substantial cooling action is usually composed of one, but if necessary, may be composed of a plurality of each to perform the cooling action.

That is, the cooling system of the kimchi storage having two or more storage compartments has an evaporator corresponding to each storage compartment, and such kimchi storage generates cold air in each storage compartment through the evaporation process in each evaporator under operation control.

1 is a configuration diagram of a cooling system of a conventional kimchi storage.

As shown in FIG. 1, when a cooling system of a conventional kimchi storage having a plurality of evaporators is schematically illustrated, upstream sides of the first evaporator 7 and the second evaporator 8 may be respectively provided with first and second capillaries 5, 6) are arranged, and the first and second solenoid valves 3 and 4 for controlling the refrigerant flow upstream of the first and second capillary tubes 5 and 6 are respectively provided, and the two solenoid valves 3 are provided. In front of 4, a condenser 2 is provided.

On the other hand, a compressor (1) is provided at the front of the condenser (2) and at the rear ends of the two evaporators (7, 8), and the first and second solenoid valves (3, 4) are a two-way open / close valve. Refrigerant flow is maintained on opening while refrigerant flow is blocked on closure.

Here, looking at the refrigerant flow, the hot gas refrigerant evaporated in each evaporator (7,8) is moved to the compressor (1), the hot gas refrigerant is compressed in the compressor (1) and converted to high temperature and high pressure to condenser (2) The gas refrigerant of high temperature and high pressure is liquefied into a liquid refrigerant of room temperature and high pressure through a heat dissipation process in the condenser (2), and then moved to each evaporator (7,8) to complete one cooling cycle.

At this time, the first solenoid valve 3 and the second solenoid valve 4 are selectively opened depending on whether the first evaporator 7 or the second evaporator 8 is operated.

For example, when the first evaporator 7 is operated, the second solenoid valve 4 is closed and only the first solenoid valve 3 is opened, so that the high pressure liquid refrigerant is discharged through the first solenoid valve 3. 1 is introduced into the capillary tube (5) to pass through the change to a low pressure liquid refrigerant, the low pressure liquid refrigerant is passed through the first evaporator (7) is evaporated by heat exchange with the ambient air to cool the first storage compartment.

On the other hand, when the second evaporator 8 is operated, only the second solenoid valve 4 is opened so that the high pressure liquid refrigerant passes through the second solenoid valve 4 to the second capillary tube 5 and the low pressure liquid. After changing into a refrigerant, the low pressure liquid refrigerant flows into the second evaporator 7 and vaporizes by heat exchange with ambient air, thereby cooling the second storage compartment.

However, in the related art, when only one evaporator 7 is operated to use one storage chamber R1, the refrigerant flow B also occurs in the other storage evaporator 8 that is not operated, and thus the storage chamber R2 is not used. There was a problem of generating an unnecessary cooling effect.

That is, when the first evaporator 7 is operated, the pressure of the refrigerant pipe drops sharply in front of the compressor 1 and induces the refrigerant flow A. At this time, the second evaporator 8 is caused by the pressure drop of the refrigerant pipe. The refrigerant remaining in the evaporation evaporated to generate an unnecessary refrigerant flow (B).

As described above, there is a problem in that a refrigerant flow occurs even in an evaporator which does not operate in a cooling system of a kimchi storage having a plurality of evaporators. To solve this problem, a solenoid valve capable of controlling a refrigerant flow is provided for each evaporator. It is also necessary to install at the rear end.

Therefore, the present invention aims to prevent the temperature change of another storage room that is not used when using only one storage room in a kimchi storage having two or more storage rooms.

Cooling system of kimchi storage equipped with a plurality of evaporators to achieve the above object,

A compressor, a condenser and a plurality of evaporators are sequentially installed along a refrigerant line, and a cooling system of a kimchi reservoir having a solenoid valve and a capillary tube installed between the condenser and each of the evaporators, wherein the outlet of each evaporator discharges a liquid refrigerant. By installing a solenoid valve to control each.

Hereinafter, preferred embodiments of the present invention will be described in detail with reference to the accompanying drawings.

Of the accompanying drawings, Figure 2 is a configuration diagram of the cooling system of the kimchi storage according to the present invention.

As shown in FIG. 2, a compressor 11 for compressing a vapor refrigerant to a high pressure is installed sequentially along the refrigerant line, and the rear of the compressor 11 is configured to heat the compressed gas refrigerant by ambient heat exchange with ambient air. A condenser 12 for liquefying at high pressure by heat dissipation is installed. At the rear of the condenser 12, two evaporators 17 and 18 are formed to vaporize the liquefied refrigerant by heat exchange with ambient air to perform a cooling operation.

In addition, first and second capillary tubes 15 and 16 are installed at the inlet side of each of the evaporators 17 and 18 to thermally expand and expand the high pressure liquid refrigerant to low pressure, respectively. First and second solenoid valves 13 and 14 for controlling the refrigerant flow are installed between the condenser 12 and the condenser 12, respectively. The first and second solenoid valves 13 and 14 are provided in front of the compressor 11 and at the outlet of each of the evaporators 17 and 18. 3 and 4 solenoid valves 19 and 20 are respectively installed.

In the meantime, the two evaporators 17 and 18 operate respectively or simultaneously according to the selection mode. The first evaporator 17 cools the first storage chamber R1 and the second evaporator 18 stores the second storage chamber R2. Cool)

At this time, the refrigerant flowing into each of the evaporators 17 and 18 is controlled by the first and second solenoid valves 13 and 14, and the refrigerant flowing out of each of the evaporators 17 and 18 is the third and fourth solenoid valves 19. , 20).

When the first evaporator 17 is operated, the first solenoid valve 13 is opened. When the second evaporator 18 is operated, the second solenoid valve 14 is opened to the respective evaporators 17 and 18. Control the refrigerant inlet.

In addition, when the first evaporator 17 is operated, the third solenoid valve 19 is opened to flow the refrigerant, and the fourth solenoid valve 20 is closed to block the refrigerant flow from the second evaporator 18. .

That is, when only the first evaporator 17 is operated, since the refrigerant flows only in the first evaporator 17 and the second evaporator 18 which does not operate does not generate unnecessary refrigerant flow, it is used when only the first storage chamber R1 is used. It is possible to prevent the temperature change of the second storage chamber (R2) that does not.

On the contrary, when only the second evaporator 18 is operated, only the fourth solenoid valve 20 is opened, and the third solenoid valve 19 is closed to block the flow of the refrigerant from the first evaporator 17, so that the second storage compartment is closed. Only (R2) is cooled.

As such, the present invention provides a flow of refrigerant from another evaporator that does not operate when a solenoid valve is installed at the outlet side of each evaporator in a kimchi reservoir having a plurality of evaporators. It can be blocked to prevent temperature changes in unused storage rooms.

As described above, by installing a solenoid valve on the outlet side of each evaporator in the kimchi storage having a plurality of evaporators, it is possible to prevent the refrigerant flow of the evaporator that is not in operation, thus, one storage chamber in the kimchi storage having two or more storage chambers When only the bay is used, it can prevent the temperature change of other storage room which is not used.
