いる。2. Description of the Related Art Conventionally, an automatic warehouse of this type is provided with a warehouse body whose inside is cut off from the outside, and a cooler for blowing cooling air into the warehouse body, and a large number of loads are vertically accommodated in the warehouse body. A large number of shelves having sections are arranged in a horizontal direction, a load is loaded into and stored in a load storage section of the shelf by a mobile crane, and the load stored in the load storage section is unloaded by a mobile crane. .

による。[0003] In the automatic freezing and refrigerated warehouse having the above-described structure, the heat energy consumed to maintain the temperature in the warehouse main body is mainly heat from the outside. The first of the invading heat enters through the heat insulating material forming the ceiling, wall and floor of the warehouse body. The second is that the cooled air is released to the outside by opening and closing of the door upon loading and unloading, and the outside air invades from the opened door by the amount of the released air.

This is because the moisture contained in the air that enters from the outside carries the external heat into the refrigerator, and this moisture is rapidly cooled by the cooler to solidify on the surface of the heat exchanger and adhere and grow as frost. I do. Since the frost adhesion growth reduces the heat transfer efficiency of the heat exchanger, it is necessary to periodically remove the attached frost. In addition to the above, heat energy consumed for maintaining the temperature in the warehouse main body includes, for example, lighting in the refrigerator and heat generated by motors and the like.

As a result, the same amount of relatively light external air invades as it is discharged to the outside.

を下げることにつながる。In the above-mentioned conventional refrigerated warehouses, generally, cooled air is blown out along the ceiling surface,
The temperature in the freezer warehouse is evenly cooled. Therefore, as a result, the blown-out air pushes up the air at the bottom in the freezer warehouse and cools this air. This air is relatively cool air in the warehouse,
This results in lowering the evaporation temperature of the refrigerator, which leads to lowering of the refrigeration efficiency.

It is an object of the present invention to provide an automatic refrigerated warehouse capable of changing a cooling method in a refrigerator and improving a cooling efficiency.

る。In the freezer and refrigerated warehouse, the temperature in the warehouse is not uneven. This temperature unevenness is caused by the heat generating part (lighting, heater,
(Motor), around the door, around the product, etc., and sometimes due to the height difference in the refrigerator. In order to reduce the temperature unevenness, the air in the refrigerator is circulated by a fan or the like so as to make it uniform through a duct or the like.

320 kcal / H Assuming that the temperature in the refrigerator is −30 ° C., specific weight Y = 1.45 kg / m 3 suction air enthalpy i1 = −7.073 kcal / kg Therefore, i2 = −8.027 kcal / kg This is −34 Equivalent to air in ° C. The temperature difference at that time is −30 − (− 34) = 4 ° C., and a temperature unevenness of at least about 4 ° C. occurs.

In this method, cold air having the lowest temperature is sucked in due to temperature unevenness caused by a vertical difference, and cooled by a cooler. The evaporating temperature TE of the cooler in this case is
Taking an example of a suction temperature of −30 ° C. and a difference ΔT = 10 ° C. from the evaporation temperature, TE = −30 ° C.−10 ° C. = − 40 ° C.

影響してくる。On the other hand, in the case of the upper suction / lower discharge according to the present invention, the highest cool air generated due to the uneven temperature is sucked and cooled by the cooler. In this case, assuming that the evaporation temperature TE of the cooler is 4 ° C., TE = (− 30 ° C. + 4 ° C.) − 10 ° C. = − 36 ° C. This difference in evaporation temperature greatly affects the coefficient of performance of the refrigerator.

により、更に上がって行く。FIG. 6 is a diagram showing the relationship between the evaporation temperature of the refrigerator and the coefficient of performance. From the figure, TE = −40 ° C. coefficient of performance = 1.66 TE = −36 ° C. coefficient of performance = 1.80 The ratio is 1.8 / 1.66 = 1.0084. That is, the 8.4% refrigeration efficiency of the upper suction / lower discharge method of the present invention is higher than that of a general lower suction / upper discharge method. This means that the running cost can be reduced in the refrigerated warehouse of the present invention. This ratio further increases due to the increase in temperature unevenness as the height inside the refrigerator increases.

流れが自然と起きる。そのため強制循環が不要となる。By making the freezing / refrigerating warehouse upper suction / lower blowing as described above, the following is also affected in addition to the above. (A) The forced circulation of cool air is not required. Since the above-mentioned relatively high-temperature cold air is sucked and the cooled air flows from the lower portion, the air flow naturally occurs to eliminate temperature unevenness. Therefore, forced circulation is not required.
