内に貯蔵し得ないという問題点があった。[Problems to be Solved by the Invention] However, as mentioned above, the temperature of the refrigerator compartment is controlled by supplying cold air of about -15°C to -20°C to the refrigerator compartment through the supply passage. Since low-temperature cold air is constantly supplied to the refrigerator compartment, food and beverages located near the cold air supply unit (5) that supplies cold air will easily freeze, resulting in a local supercooling phenomenon, and the cold air will be uniformly distributed in the refrigerator compartment. A phenomenon called "drift" occurs in which cold air collects in a certain area, resulting in uneven temperature in the refrigerator compartment. Therefore, there is a problem in that unless the above-mentioned local overcooling phenomenon and cold air drift phenomenon are improved, fresh food cannot be stored in the refrigerator compartment with higher reliability.

施することになるものである。The operation of the regulating device configured as described above is controlled through a cold air supply control program of the system microprocessor, which is indicated by reference numeral 31 in FIG. The system microprocessor (31) regulates the temperature within the refrigerator compartment through a series of processing steps shown in the control program flowchart shown in FIG. The method for adjusting the temperature of the refrigerator compartment will be explained below according to a flowchart. First temperature sensor (23
), the temperature sensed at T23 is assumed to be T23, the step of processing this (step 100) and the step of comparing and determining the magnitude of the above-mentioned sensed temperature T23 with TH, which is the highest set temperature (
If the sensed temperature becomes larger than the set temperature value at this stage, the suction fan (21) is rotated by the motor (24) at the same time (step 102).
, step 103), the supply fan (25) is connected to the motor (2).
6) to operate (step 108, step 109)
As the cold air inside the refrigerator room is forcibly circulated, the temperature inside the refrigerator room is made uniform.On the other hand, if the sensed temperature is lower than the set temperature value, the process returns to step 100 (No). Next, assuming that the temperature sensed by the second temperature sensor (28) is T28, a step of processing this (
Step 104), subtract the set temperature TL from the above sensed temperature T28, and check whether this value is greater than 0 (step 105). If this value is greater than 0, that is, the sensed temperature T28 is the set temperature. If the temperature is higher than TL, the answer is Yes, and the suction damper (22) is finely closed and adjusted (steps 106, 107), and at the same time, the supply passage (20
) The supply damper (27) installed in the opening/closing device (27
a) Supply damper (27) through the step motor which is
The opening is finely adjusted (steps 110 and 111). Then, when the above process is completed, the suction damper (22) and the supply damper (27) are adjusted while continuously sensing the temperature in the refrigerator compartment through the second temperature sensor (28) according to the process that is repeated in step 104. to control the flow rate of cold air. In case, step 10 above
If the value of the sensed temperature T28 becomes smaller than the set temperature TL in step 5, the motors (24) and (26) of the compressor (4), suction fan (21), and supply fan (25) of the refrigerator will all be stopped if the answer is No. (Step 112, Step 114). Therefore, the supply damper (
27), opening and closing of the suction damper (22) installed on the cold air intake (30), and suction fans (21) installed in the cold air intake (30) and the cold air supply port (29), respectively.
) and the supply fan (25), the cold air intake (3
0) and the cold air supply port (29) respectively detected by the first and second temperature sensors (23) and (28). , low-temperature cold air is supplied from the freezer compartment to the refrigerator compartment through the supply passageway (20) and the cold air inlet (
30), the temperature inside the refrigerator compartment is adjusted through a circulation flow in which cold air is sucked in, mixed, and discharged through the refrigerator compartment.

．． 3KJ/m3 °C, and water at 0 °C is Cw = 4224
KJ/m3°C, and since food and drink contain a large amount of water, the volume equivalent specific heat of food and drink is also much larger than that of air. Therefore, once the refrigerating temperature in the refrigerator room is 3
Food and drink cooled at a temperature of 3°C do not change easily like air, so if the surrounding air temperature is maintained at 3°C, the food and drink will continue to remain cool. In addition, at night when the door of the refrigerator compartment is not opened frequently, if the cold air in the refrigerator compartment rises to a specified temperature, for example, 5℃ or higher, the temperature of the cold air supplied to the refrigerator compartment will be kept at 0℃~3℃. By supplying the food and drink at a constant temperature, the stored food and drink can be kept continuously cooled at a temperature of around 3°C. In addition, if the refrigerator compartment door is opened frequently and the cold air inside the refrigerator compartment leaks, causing the temperature of the refrigerator compartment to rise, the specific heat of the food and beverages is greater than that of air, so the food and beverages in the refrigerator compartment will be at a lower temperature. By maintaining the temperature at 3°C and supplying cold air of 0°C to 3°C to the refrigerator compartment, the temperature of the refrigerator compartment does not drop below 0°C, so food and drinks do not freeze.
