The present invention relates to a central cold air supply type chiller, and more particularly, to a central cold air supply type chiller that receives and cools the cold air required for cooling in a refrigerator as needed from the outside.

In general, the refrigerator is divided into a freezer compartment for storing ice-making containers and frozen foods at a set temperature, and a refrigerating compartment in which refrigeration objects are stored, and a refrigeration cycle device is installed therein and circulated in a refrigeration cycle of evaporation, compression, condensation, and expansion. In order to keep the inside frozen and refrigerated, by absorbing external heat from the evaporator in the circulation circuit.

A blower 12 forcibly blowing the air, a cold air guide passage 13 formed in the main body 1 to guide the cold air generated by the freezing cycle 30 to the refrigerating chamber 20, and integrated into the main body 1. Formed in the partitioned plate 15 to cool the freezer compartment 10 and guide the cold air to be cooled again according to the continuous operation of the freezing cycle 30. It consists of a cold air circulation path 17 for the refrigerating chamber to guide the cooling again according to the continuous operation of the refrigeration cycle (30).

The refrigerating cycle 30 is installed at the rear lower end of the main body 1 to compress the low-temperature, low-pressure gas refrigerant into a high-temperature, high-pressure gas refrigerant and the high-temperature, high-pressure gas refrigerant at high temperature A condenser 32 for converting a high pressure liquid refrigerant, a capillary tube 33 for converting the high temperature and high pressure liquid refrigerant into a low temperature, low pressure liquid refrigerant, and a rear of the freezing chamber 10 of the main body 1. It is configured to the evaporator 34 to evaporate the low-temperature, low-pressure liquid refrigerant to a low-temperature, low-pressure gas refrigerant.

In the conventional refrigerator configured as described above, in order to store fresh food stored in the freezer compartment 10 or on the shelf 22 mounted in multiple layers in the refrigerator compartment 20 for a long time, the refrigerator compartment door is supplied with power. The compressor 31 constituting the refrigeration cycle 30 is driven by receiving a control signal of a controller (not shown) mounted inside the 21 to compress a low-temperature, low-pressure gas refrigerant into a high-temperature, high-pressure gas refrigerant. The compressed high-temperature, high-pressure gas refrigerant is condensed into a high-temperature, high-pressure liquid refrigerant while passing through the condenser 32.

The condensed high temperature and high pressure liquid refrigerant is converted into a low temperature and low pressure liquid refrigerant through a capillary tube 33, and the low temperature and low pressure liquid refrigerant is converted into a low temperature and low pressure gas refrigerant through an evaporator 34. As it evaporates, the surrounding air is heat-exchanged by the evaporation of the evaporator 34 to cool the surrounding air, thereby generating cold air.

Part of the cold air generated as described above is forcedly blown according to the rotation of the blower 12 installed at the rear of the main body 1, enters the freezing chamber 10, cools it to a predetermined temperature, and freezes food. Guided through the cold air flow path 13 formed in the entering the refrigerating chamber 20 to cool the refrigerating compartment 20 to a predetermined temperature so that food is refrigerated.

In this way, the cold air enters the freezing chamber 10 and the refrigerating chamber 20 to cool the freezing chamber 10 and the refrigerating chamber 20, and then the cold air of the freezing chamber is continuously cooled by the operation of the refrigerant cycle 30. It is guided to the evaporator 34 through the cold air circulation path 16 for the freezer compartment 10 formed in the diaphragm 15 to continuously generate the cold air by the evaporation action, the cold air in the refrigerating compartment 20 of the main body 1 It is led to the evaporator 34 through the cold air circulation path 17 for the refrigerating chamber 20 formed in the diaphragm 15 to continuously generate cold air by the evaporation action.

However, in the conventional refrigerators as described above, when a plurality of refrigerators are used, compressors and other equipment constituting a freezing cycle are mounted and operated in each refrigerator, so that the compression and cooling efficiency of the compressor is low, and the electricity consumption is high. There is a problem.

An object of the present invention devised in view of the above-described point is to provide a central cold air supply type cooling apparatus that receives and uses as much cold air as necessary for cooling the refrigerator.
