Description

Cold Storage {COLD STORAGE CHAMBER}

The present invention relates to a cold store, and more particularly to a cold store that can be stored at low temperatures by reducing the temperature deviation of agricultural products, fisheries, livestock products (hereinafter referred to as "store").

In order to store stocks for a long period of freshness, the stocks are usually stored in a frozen store or a cold store. When freezing and storing the storage in the frozen warehouse, the storage is stored in the frozen state, which has the advantage that the storage can be stored for a long time, while the power loss is large and the thawing process is required to thaw to cook the storage. The freshness in the nutrients for the stock is destroyed, the taste of the stock is degraded, as well as the thawing time takes a lot of problems.

Therefore, the low temperature storage method has been in the spotlight in recent years due to the advantage of storing the stored product at a low temperature around 0 ° C. to prevent the destruction of nutrients and deterioration of taste and to cook the stored product immediately. In addition, such cold storage can be sold at a much higher price than frozen storage, which is very economical for the storage supplier.

However, in the conventional low temperature warehouse for storing the storage at low temperature, there is a problem that it is difficult to store the storage for a long time while maintaining the freshness due to the large temperature deviation with respect to the desired storage temperature. This is very detrimental to the supplier of the reservoir as the shipping of the water cannot be controlled at will.

The present invention has been made in view of the above-mentioned conventional problems, and the purpose of providing a low-temperature warehouse that can be stored at a low temperature, optionally frozen, as well as freezing storage, and can reduce the variation in storage temperature. do.

You may be.

Next will be described a method for low-temperature storage of the storage in the cold warehouse according to the present invention configured as described above.

First, when the compressor installed in the machine room 5 is driven through the controller 51, the refrigerant is compressed by the compressor to be supplied to the condenser, and the refrigerant condensed by the condenser is supplied to the expansion valve and the evaporator 53 installed in the freezer compartment, and then to the compressor. Circulated to As the evaporator 53 evaporates during the circulation of the refrigerant, the internal air of the freezer compartment 4 is exchanged with the refrigerant to cool air, and is selectively supplied to the storage chamber 1 or the precooling chamber 3, and the storage chamber ( 1) or the air inside the precooling chamber 3 is selectively recovered to the freezing chamber 4.

Control of the internal air flow in the low temperature warehouse according to the present invention is made by the controller (51). That is, if the temperature for the storage compartment 2 is set to a desired temperature, the temperature sensing signal of the temperature sensor installed in the storage compartment 2 is transmitted to the controller 51 so that the supply blower when the temperature of the storage compartment 2 is higher than the set temperature. 61 is driven. The cold air of the freezing chamber 4 is introduced into the upper supply duct 25 through the supply blower 61 by the operation of the supply blower 61, and the air introduced into the upper supply duct 25 is vented. It spreads into the storage compartment 2 through the 26.

In this way, when the temperature inside the storage compartment 2 decreases to a low temperature due to the cold air diffused into the storage compartment 2 and falls below the set temperature or the set temperature or less, the operation of the supply blower 61 is stopped, thereby causing the cold wind to the storage compartment 2. The supply is cut off and the circulation blower 63 is driven. As such, when the circulation blower 63 is driven, the air in the lower portion of the storage compartment 2 is uniformly supplied to the upper portion of the storage compartment 2 through the upper supply duct through the circulation blower 63, thereby reducing the temperature difference between the upper and lower sides.

In addition, when it is detected that the temperature of the storage compartment 2 rises above the set temperature again by stopping the supply of the cold wind, the supply blower 61 is driven and the circulation blower 63 is stopped to repeat the above process. ) Can be maintained at a constant low temperature with almost no deviation from the set temperature.

On the other hand, the temperature of the precooling chamber 3 is adjusted according to the drive of the precooling blower 65. That is, when the temperature of the precooling chamber 3 is higher than or equal to the set temperature, the precooling blower 65 is driven so that the cold air of the freezing chamber 4 passes through the supply hole 45 through the precooling blower 65. The cold air introduced into the lower supply duct 35 is diffused into the precooling chamber 3 through the vents 36. In addition, the air inside the precooling chamber 3 flows into the second recovery duct 37 through the vent holes 38, and the air introduced into the second recovery duct 37 passes through the recovery hole 47. 4) is recovered. In addition, when the internal temperature of the precooling chamber 3 falls below the set temperature, the operation of the precooling blower 65 is stopped, and thus the supply of cold air to the precooling chamber 3 is stopped. By repetition, the temperature inside the precooling chamber 3 can be kept constant with little variation.

According to the present invention, when storing the storage in the storage compartment 2, the storage compartment is stored in the precooling chamber 3 through the precooling chamber entrance 32 without storing the storage immediately in the storage compartment 2. (1) It is preferable to lower the temperature of the stored product in a state close to the internal temperature, and then store the pre-cooled stored product in the precooling chamber 3 in a proper place in the storage chamber 2 through the connecting door 33. In this way, since the storage having a high temperature is immediately stored in the storage compartment 2, the temperature deviation of the storage compartment 2 can be prevented from occurring so that the storage can be stored for a long time while maintaining the freshness. Stored goods that require freezing are stored in the freezer compartment 4 through the freezer compartment door 41.

On the other hand, when the temperature of the outside air is lower than the internal temperature of the storage compartment 2 of the low temperature warehouse according to the present invention, the temperature of the storage compartment 2 can be kept constant at the set temperature by operating the heater 7.

In the low temperature warehouse according to the present invention configured as described above, the pre-cooling chamber 3 is installed to maintain the temperature of the storage compartment 2 almost without deviation from the set temperature, and the cold air supply and circulation to the storage compartment 2 By controlling the driving of the blowers 61 and 63, the storage can be stored at low temperature without temperature deviation, and thus the storage can be stored for a long time without losing freshness. Therefore, the shipment of the storage can be arbitrarily adjusted to increase economics and protect the health of consumers.

In addition, in the storage warehouse according to the present invention can be stored in the freezer compartment (4) as needed to freeze storage can be stored in a variety of ways depending on the storage.

In addition, in the storage warehouse according to the present invention, when the temperature of the outside air is lower than the set temperature of the storage chamber 2, by operating the heater 7 can not only safely store the storage, but also in this case can be effectively stored low temperature.
