Energy Saving Large Size Freezer/refrigerator}

The present invention relates to a large refrigerating/refrigerating device used in a refrigerated warehouse or business, and more particularly, a refrigerating space for freezing frozen foods such as meat and a refrigerating space for refrigerating refrigerated foods such as vegetables, respectively. The present invention relates to an energy-saving large-sized refrigerating/refrigerating device capable of efficiently storing food by appropriately adjusting the amount of stored food and at the same time partitioning the refrigerating/refrigerating space from a worker's entry/exit passage.

The large refrigerating/refrigerating device is a refrigerating/refrigerating device applied to business places such as restaurants or warehouses storing large quantities of agricultural, marine and livestock products. Based on the refrigerating cycle, a unit cooler is installed inside the insulated space to As shown in FIG. 1, the unit cooler 2 serving as an evaporator is installed inside the main body 1, and the condensing unit 3 and compressor 4 serving as a condenser are installed in the main body 1, as shown in FIG. ) is installed outside the main body, the refrigerant that has passed through the unit cooler 2 is compressed in the compressor 4, the high-temperature and high-pressure vaporized refrigerant is liquefied at high temperature and high pressure in the condensing unit 3, and the expansion valve 5 After being liquefied at low pressure, the unit cooler 2 exchanges heat with air while repeating the cycle of evaporating at low temperature and low pressure in the unit cooler 2 to supply cold air.

Since such a large refrigerating/refrigerating device has a large storage space, a worker enters and exits the freezer and deposits or withdraws stored items. A door 11 is installed on the front side of the main body 1, and a door 11 is installed inside the device. A connected passage (P) is formed and a shelf (S) for storing storage is installed on one side of the passage.

According to the energy-saving large-sized refrigerating/refrigerating device of the present invention, a shelf is partitioned into freezing and refrigerating areas by a variable insulating wall and the discharge of cold air is independently controlled for each area, thereby refrigerating and refrigerating without a separate small refrigerator. Food can be stored appropriately as needed, and the air curtain divides the shelf, that is, the storage area and the operator's aisle area, thereby minimizing the discharge of cold air to the aisle area where refrigeration is unnecessary, thereby improving energy efficiency and at the same time improving the worker's It is possible to minimize the inconvenience of loading or withdrawing stored goods in a low-temperature space.

A door 11 is installed on the front side of the main body 1, a passage P connected to the door is formed inside the main body 1, and a shelf S for storing storage is installed on one side of the passage P. In that it is the same as/similar to a conventional general large refrigerating/refrigerating device, the cold air distribution cover 21 is coupled to the front of the unit cooler 2, and the cold air distribution cover 21 extends from the cold air distribution cover 21 to the shelf S side. A distribution duct 23 is installed, and a variable insulating wall 30 is provided so that the longitudinal direction of the shelf S can be partitioned at an arbitrary position as needed.

In the case of the present embodiment, a plurality of shelves (S) are arranged, and the variable insulation wall (30) is disposed at an appropriate position between the shelves (S), that is, at the boundary between the frozen food loading section and the refrigerated food loading section. Bar, FIG. 2A shows an example in which the variable insulation wall 30 is arranged so that the frozen food loading sections (S1, S2, S3) are larger than the refrigerated food loading sections (S1), and in the case of FIG. 2B, the frozen food An example in which the variable insulation wall 30 is arranged so that the stacking section S1 is larger than the stacking sections S2, S3, and S4 of refrigerated food is shown.

In the case of this embodiment, the variable insulating wall 30 in the form of a panel is taken as an example, but the variable insulating wall 30 can be of any shape as long as it has insulating properties and can prevent heat transfer between the freezing zone and the refrigerating zone. It is also possible to form a plurality of through holes through which the support rods of the shelf S pass through the heat-insulating sheet material in the form of a low curtain so as to slide along the longitudinal direction of the shelf S.
