  There is known a large-scale freezer warehouse in which various articles that need to be stored frozen are carried in a transport vehicle or the like and stored in large quantities. Such a freezer warehouse is constructed airtight so that a structural housing such as an outer wall is constructed by RC construction or the like and is not affected by the temperature and humidity of the outside air.

  In a freezer warehouse, when a crack occurs in an outer wall or the like in contact with the outside air, the outside air enters the freezer warehouse through the crack. In particular, the air in the freezer warehouse is cooled to reduce the volume, and the internal pressure becomes lower than the atmospheric pressure, so that outside air easily enters the freezer warehouse. The outside air contains moisture, and is cooled when passing through the outer wall or the like, resulting in condensation, and the generation of condensed water may be observed in the freezer warehouse.

  Condensed water, for example, travels from the cracked site to the inner surface of the outer wall, etc., accumulates on the floor, freezes, forms icicles along the inner surface, and freezes around articles placed on the outer wall. I'll be relaxed. Freezing on the floor is dangerous because it may cause the worker to fall over or cause the transport vehicle to slip, and the formation of icing around the icicles and the goods may interfere with the handling of the goods. It is also dangerous.

  Condensed water is not limited to the above-described cracks in the outer wall and the like, but may also occur in a structural slit as a stress release means provided in order to ensure the structural integrity of the refrigerated warehouse, a gap in an expansion joint, or the like.

  As mentioned above, dew condensation water can be generated at various unspecified locations and also at multiple locations simultaneously. As a countermeasure against such dew condensation water, for example, it is conceivable to place a bucket in each spot where dew condensation water is seen, receive the dew condensation water with this bucket, and carry the bucket to the outdoors and throw it away when it accumulates to some extent. However, such an operation is inefficient because it takes time and effort even in a small-scale freezer warehouse as well as a large-scale freezer warehouse.

  In addition, it is conceivable to provide drainage ports at predetermined locations such as the outer wall and to install dredging at locations where dew condensation water is seen to guide the dew condensation water to the drainage port. However, if the refrigerated warehouse is large, the condensed water may freeze in the tub before it reaches the drain outlet. It becomes a problem in securing.

  Condensed water treatment in a freezer warehouse can be installed anywhere according to the location of occurrence, easy to move for installation, simple structure, compact size, low cost production, and running It has been desired to devise a processing apparatus that is low in cost.

  The present invention was devised in view of the above-mentioned conventional problems, and is portable for the treatment of condensed water generated in a freezer warehouse, and is simple in structure and compact and can be easily installed anywhere. An object of the present invention is to provide a dew condensation water treatment apparatus for a refrigerated warehouse that can be manufactured at a low cost and has a low running cost.

  A dew condensation water treatment apparatus for a freezing warehouse according to the present invention is a dew condensation water treatment apparatus for a freezing warehouse for treating dew condensation water in which moisture of outside air entering the freezing warehouse is condensed, and has an opening, A portable heat insulation box installed in the freezer warehouse, and installed in the freezer warehouse, inserted into the heat insulation box through the opening, and guides the condensed water droplets into the heat insulation box. A portable lid member, a portable lid that is detachably provided on the heat insulation box and covers the opening so as to be adjustable in opening, and is provided in the heat insulation box to vaporize condensed water and to open the opening. And a portable heating element that dissipates outward from the section.

  A humidity control layer is formed on the inner surface of the heat insulating box.

  The lid is provided with a heat reflecting member on the back surface facing the heat insulating box.

  The dew condensation water treatment apparatus for a freezer warehouse according to the present invention is portable for the treatment of dew condensation water generated in a freezer warehouse, has a simple structure, is compact and can be easily installed anywhere, and is inexpensive. It can be manufactured and low running costs can be secured.

It is a sectional side view showing the schematic structure of one suitable embodiment of the dew condensation water treatment apparatus of the frozen warehouse concerning the present invention.

  Hereinafter, a preferred embodiment of a dew condensation water treatment apparatus for a refrigerated warehouse according to the present invention will be described in detail with reference to the accompanying drawings. FIG. 1 is a side sectional view showing a schematic configuration of a dew condensation water treatment apparatus for a refrigerated warehouse according to the present embodiment.

  The freezer warehouse 1 is constructed as a building having airtightness by RC construction or the like for the entire housing structure including the wall 2 and the floor 3. When a large amount of articles are stored, it is constructed as a large space building. The freezer warehouse 1 may be provided with a structural slit or an expansion joint for the purpose of releasing thermal stress due to temperature or stress generated by an earthquake. In the freezer warehouse 1, a wide variety of articles that need to be stored frozen are carried and stored.

  Since the air in the freezer warehouse 1 is cooled and the volume is reduced, the internal pressure of the warehouse is generally lower than the atmospheric pressure. Moreover, the inside temperature and humidity are kept substantially constant in the freezer warehouse 1. These pressure management and temperature / humidity management are performed by an air conditioning control device as is well known.

  In the freezer warehouse 1, a dew condensation water treatment device 4 that treats the dew condensation water w in which moisture of the outside air entering the freezer warehouse 1 is condensed is provided. The dew condensation water treatment apparatus 4 in the refrigerated warehouse according to the present embodiment is mainly composed of a heat insulating box 5, a gutter member 6, a lid body 7, and a heating element 8.

  The heat insulation box 5 is a container for storing the dew condensation water w therein, and is formed of a lightweight and heat insulating material such as expanded polystyrene. Thereby, the inside of the heat insulation box 5 can be insulated from the cold air in the freezer warehouse 1 and kept warm. The heat insulation box 5 has an opening 5 a that is opened toward the space in the freezer warehouse 1. In the example of illustration, the opening part 5a is formed in the heat insulation box 5 toward the upper direction. The opening 5a may be formed at any position of the heat insulating box 5 as long as the accumulated condensed water w does not leak out.

  The heat insulation box 5 is made of a lightweight material and is portable so that it can be carried by a worker (capacity). The heat insulation box 5 is formed with a size of depth 300 mm × width 500 mm × height 160 mm, for example. The heat insulation box 5 is installed in the freezer warehouse 1 by placing it on the floor 3. The installation position of the heat insulation box 5 may be selected according to the location where the condensed water w is generated, and the heat insulation box 5 is carried and installed at the selected position.

  The eaves member 6 is installed in the freezer warehouse 1, and moisture from outside air that enters the freezer warehouse 1 through cracks 9, structural slits, gaps in the expansion joints, etc. is condensed to form droplets, and the cracks 9 are generated from the 9 places of the cracks. It is a guide member that guides the dew condensation water w that oozes out to the heat insulation box 5 and is formed of a lightweight material such as a synthetic resin material. The eaves member 6 is formed in a form suitable for water passage, such as a channel shape or a hollow pipe shape.

  At the upper end portion of the flange member 6, there is formed a receiving port 6 a for receiving the dewed water w that oozes out from a spot where the crack 9 or the like oozes out or travels along the inner surface of the outer wall 2 or the like. The lower end 6b of the eaves member 6 is inserted into the heat insulating box 5 through the opening 5a. The eaves member 6 may be configured with a telescopic structure whose length can be adjusted, or a flexible material is adopted so that installation between the seepage spot (for example, crack 9) and the heat insulating box 5 is flexible. Then, it may be formed so as to be flexible and deformable, such as a water supply hose.

  The receiving port 6a of the gutter member 6 receives the condensed water w generated in the freezer warehouse 1, and the condensed water w received by the receiving port 6a reaches the inside of the heat insulation box 5 through the gutter member 6, and the heat insulation box 5 is stored inside. The eaves member 6 is made of a lightweight material and is portable so that it can be carried by the operator. A plurality of eaves members 6 may be inserted into one heat insulation box 5 to guide the condensed water w from a plurality of locations.

  The lid body 7 is formed of the same material as that of the heat insulating box 5. Of course, you may form with a different lightweight material. In order to cover the opening 5a of the heat insulating box 5 so that the opening degree can be adjusted, the lid body 7 is formed with a size that can fully close the opening 5a. The lid body 7 may have a plate shape or a roll shape that can be wound up. The lid 7 is detachably provided in the opening 5 a of the heat insulating box 5.

  When the lid 7 is in the form of a plate, the mounting position with respect to the opening 5a is shifted, and in the case of a form that can be wound up, by partially adjusting the winding amount, the opening 5a is partially covered, A gap 10 generated between the heat insulating box 5 and the lid 7 is adjusted. The lid 7 partitions the inside of the heat insulation box 5 from the freezer warehouse 1 by partially covering the opening 5a, thereby suppressing the intrusion of cold air into the heat insulation box 5 and affecting the vaporization of the condensed water w. The apparent capacity of the heat insulation box 5 is adjusted. The gap 10 between the heat insulating box 5 and the lid 7 serves as a passage for inserting the eaves member 6 into the heat insulating box 5, and allows the air in the freezer warehouse 1 to flow into the heat insulating box 5. It becomes a passage through which the air flows out into the freezer warehouse 1. The gap 10 is set to a width of about 10 cm, for example.

  The lid 7 is made of a lightweight material and is portable so that it can be carried by an operator.

  The heating element 8 is provided in the heat insulation box 5 in order to raise the temperature in the heat insulation box 5. When the temperature inside the heat insulation box 5 is raised by the heating element 8, the relative humidity of the air in the heat insulation box 5 is lowered, and the air is in a dry state. For example, when the temperature in the freezer warehouse 1 is 0 ° C. and the relative humidity is 70%, when the temperature in the heat insulation box 5 is 20 ° C., the relative humidity is less than 20%, and the state is very dry. As a result, the dew condensation water w evaporates and is dissipated from the gap 10 into the refrigeration warehouse 1 outside the heat insulation box 5 by the air flow generated in the heat insulation box 5. The heating element 8 may be any type. For example, an incandescent bulb is inexpensive, has a low risk of fire, and is extremely easy to handle.

  To supply power to the heating element 8, the power cord 8a of the heating element 8 is pulled out of the heat insulation box 5 through the gap 10, and the drawn power cord 8a is connected to a power source, specifically, a commercial power source or a battery. That's fine. The heating element 8 is small enough to be accommodated in the heat insulating box 5, and is therefore portable and portable by the operator.

  The lid 7 is provided with a heat reflecting member 11 such as an aluminum foil on the back surface facing the heat insulating box 5. The heat reflecting member 11 reflects the heat generated by the heating element 8 and efficiently raises the temperature in the heat insulating box 5. In addition, the heat reflecting member 11 also exhibits a heat shielding action along with the heat reflecting action, and blocks cold heat acting on the inside of the heat insulating box 5 from the freezer warehouse 1 through the lid body 7. The heat reflecting member 11 prevents the lid body 7 from being deteriorated by heat.

  A humidity control layer 12 is formed on the entire inner surface of the heat insulating box 5. The humidity control layer 12 is formed by applying a known humidity control material. The humidity control layer 12 absorbs moisture when the humidity is high and releases moisture when the humidity is low, thereby maintaining the humidity environment in the heat insulating box 5 in a state where vaporization of the condensed water w by the heating element 8 can be promoted. It is like that.

  Next, the effect | action of the condensed water processing apparatus 4 of the refrigeration warehouse concerning this embodiment is demonstrated. The heat insulation box 5 is installed on the floor 3 or the like in the vicinity of the dew condensation water seepage point (for example, the crack 8) in the freezer warehouse 1. The lower end portion 6 b of the eaves member 6 is inserted into the heat insulating box 5, receives the dew condensation water w at the receiving port portion 6 a, and guides it to the heat insulating box 5. The heating element 8 is installed in the heat insulating box 5, and the opening 5 a of the heat insulating box 5 is partially covered with the lid 7. Power is supplied to the heating element 8 to raise the temperature in the heat insulating box 5.

  The condensed water w guided and accumulated in the heat insulation box 5 is vaporized in the heat insulation box 5, and is dissipated from the gap 10 into the freezer warehouse 1. Since the freezer warehouse 1 has a large volume compared to the vaporized condensed water w such as a large space, the vaporized condensed water w is not recondensed as the entire relative humidity is increased. Moreover, re-condensation is prevented by adjusting the humidity by the air conditioning control device provided in the freezer warehouse 1.

  In the dew condensation water treatment apparatus 4 of the refrigerated warehouse according to the present embodiment described above, the heat insulating box 5 having the opening 5a and installed in the refrigerated warehouse 1, the refrigerated warehouse 1, and the opening It is inserted into the heat insulation box 5 through the part 5a, and is provided in the heat insulation box 5 so as to be attachable / detachable, and the opening 5a is adjusted in opening degree. Since the cover body 7 that can be covered and the heating element 8 that is provided in the heat insulating box 5 and vaporizes the condensed water w to dissipate outward from the opening 5a, the lid body 6 receives and accumulates it. The condensed water w can be vaporized in the heat insulation box 5, and the temperature in the heat insulation box 5 partially covered with the lid body 7 is increased by the heating element 8 in order to avoid the influence of the cold air in the freezer warehouse 1. When heated, the dew condensation water w can be efficiently vaporized and dissipated. Therefore, labor and time such as receiving and throwing away the dew condensation water in a bucket can be eliminated, and the dew condensation water can be treated efficiently.

  Moreover, the heat insulation box 5, the eaves member 6, the lid 7 and the heating element 8 are all portable and can be carried by an operator. The structure is simple and compact and can be easily installed anywhere. Further, it can be manufactured at a low cost, and it is possible to secure a low running cost by only supplying power to the heating element 8.

  Since the temperature and humidity in the heat insulation box 5 can be maintained in a state in which the condensed water w is easily vaporized by the heating element 8 and the humidity control layer 12, the temperature drop in the heat insulation box 5 due to the vaporization of the condensed water w. The dew condensation water w can be efficiently vaporized even when the dew condensation water w of about 0 ° C. constantly flows in.

  The heat reflecting member 11 of the lid body 7 can appropriately ensure the temperature rise and temperature maintenance in the heat insulating box 5 and can prevent thermal degradation of the lid body 7.
