Definitions
- the present invention relates to a subcooling cooler, and more specifically, to a subcooling cooler capable of reducing the frequency of operation of a compressor, reducing the amount of cool air outflow when the door is opened, and uniformly supplying low-speed cool air into the cooler. will be.
- the supercooling refers to a phenomenon in which a phase change does not occur even if the temperature of the substance falls below the phase change temperature in the process of cooling the substance.
- a substance has a stable state according to each temperature, and if the temperature is gradually changed, the constituent atoms of the substance maintain a stable state at each temperature and follow the change in temperature. However, if there are not enough nuclei to form crystals in the material, the phase change does not occur even if the temperature of the material is lowered to a temperature below the phase change temperature.
- the cooling chamber disclosed in the above publication includes a cooling chamber 2 for accommodating a container P for a liquid beverage, a heat exchanger 9 for cooling air in the cooling chamber 2, as shown in FIG.
- the cooling duct 5 containing the heat exchanger 9, the inlet 10 installed in a part of the cooling duct 5, and a cold air outlet installed at a position different from the inlet 10 of the cooling duct 5 ( 12), a cold air supply duct 6 for circulating air in the cooling chamber 2, an inlet 15 provided at one end of the cold air supply duct 6, and air in the cold air supply duct 6
- the cooling duct 5 draws air in the cooling chamber 2 from the inlet 10 and cools it in the heat exchanger 9, and then blows it out through the cold air outlet 12,
- the cold air supply duct 6 is provided from the side of the cooling chamber 2 in the vertical direction of the cooling chamber 2, and the inlet 15 faces the cold air outlet 12 of the cooling duct 5 At the same time, it faces the inside of the cooling chamber 2, and the fan 16 is characterized in that intake air into the cold air supply duct 6 from the inlet 15 is performed.
- the conventional cooler supplies a suction fan 11 for supplying the air in the cooling chamber 2 to the cooling duct 5 and the cool air cooled through the heat exchanger 9 to the cold air supply duct 6
- the fan 16 is composed of a rotating fan such as an electric fan blade.
- the direction of the air is biased to one side, which causes a variation in the cold air temperature depending on the location in the cooler.
- the number or arrangement of the ventilation holes 20 through which the cold air is discharged into the cooling chamber 2 is adjusted, but this configuration alone is limited in reducing the deviation of the temperature of the cold air. There is.
- the container P is mounted on the plate-shaped shelf plate 3, and the cold air discharged from the ventilation hole 20 is caused by the upper and lower surfaces of the shelf plate 3 Blocked, there is a problem that the circulation of cold air in the cooler is delayed. For this reason, the temperature of the cold air varies depending on the location in the cooler.
- the air in the cooler is supplied to the cooling duct 5 through the suction fan 11 and cooled by heat exchange with the heat exchanger 9, and then the cold air supply duct 6 is opened. Then, it is directly ejected into the inside of the cooler through the cold air outlet 12. Accordingly, the temperature of the cold air having a lowered temperature passing through the heat exchanger 9 increases in temperature while passing through the relatively long cold air supply duct 6, so that the temperature difference between the upper and lower portions increases even in the cooler (for example, , When the temperature in the cooler is set to -6°C, the actual heat exchanger temperature may drop below -20°C). For this reason, the temperature of the container P varies depending on the position in the cooler, and the probability of freezing of the container P increases. In addition, since cold air is directly ejected into the inside of the cooler through the cold air outlet 12, the ejection speed is relatively high, so that when the user opens the door 7, the amount of cold air that escapes to the outside increases.
- a heater is used to prevent the temperature inside the cooler from increasing due to heat transfer to outside air or the outflow of cold air due to the opening and closing of the door, and to smooth the temperature change in the cooler, as well as 1 horsepower or 1/2 A large-capacity compressor of horsepower over-spec is used, and the compressor experiences frequent ON/OFF. For this reason, in the case of a conventional subcooling cooler, a loud noise of 60db or more is generated, energy efficiency is also inferior, and the life of the compressor is shortened.
- the present invention is to solve the problems of the prior art as described above, the problem to be solved by the present invention is to reduce the frequency of operation of the compressor, reduce the amount of cold air outflow when the door is opened, It is to provide a supercooled cooler that can supply evenly.
