Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to an energy-saving low-temperature warehouse that can be constructed at low cost by taking advantage of abandoned road tunnels, etc., and has low running costs.

Conventionally known low-temperature warehouses have a structure in which storage temperature and humidity are controlled by a refrigerator and a humidifier. Therefore, the storage fee for stored items in this cold storage is:
The amortization of the equipment investment (initial cost) and the running cost during storage make it quite expensive. This invention was made in view of the above circumstances, and its purpose is to create an energy-saving type with low initial cost and running cost. Our goal is to provide a cold storage facility, and by using the return tunnel, etc., we will be able to use the I! J
! i! Attaching the device, the fog force formed at the entrance -
In addition to introducing high-humidity air into the inside of the refrigerator (inside the refrigerator), even when the outside temperature is negative, the latent heat of condensation of the water in the fog curtain allows air with a positive temperature to be introduced into the refrigerator. This is what I did.

The present invention will be explained below with reference to the drawings. 1 and 2 show an embodiment of the present invention, and reference numeral 1 in the figures indicates a return tunnel. At the upper ends of both entrances 1a and lb of this tunnel 1, there are spray devices i12, respectively.
a, 2 b are attached, and these two people ro 1a
, 1bK7 long curtains 3a, 3b can be formed. The above spray device 1ft2a, 2
b is configured to utilize the drinking water etc. that are incidental to the tunnel 1.

In the above configuration, outside air is introduced into the refrigerator due to the temperature difference between the inside and outside air or the direction of the wind, and when the inside of the refrigerator is ventilated, the spray device 2a (2b) on the wind direction side is used at the inlet 1a (l
If the 7-hole curtain 3a (3b) is formed in b), low-humidity outside air can be introduced into the refrigerator as high-humidity air, and the interior of the refrigerator can be maintained in a high-humidity state, and the outside temperature can be kept below zero. Even the fog curtain 3a (3b)
The latent heat released when the water vapor and minute droplets condense inside raises the outside temperature that is introduced into the refrigerator, resulting in positive temperatures and high humidity, and negative temperatures that cause low-temperature damage.4 can be stored for a long period of time. In addition, this low-temperature warehouse can be installed very cheaply by simply installing a fog device at the entrance of the mine road, and can use water for spraying, river water, etc. that comes with the mine road, and its running costs are also low. It is very inexpensive because it only requires energy to drive the spray device.

As explained above, this invention uses a mine road such as a return tunnel, and installs a fog device at the entrance of the mine road, and uses a 7-meter curtain formed at the entrance to create high-humidity air inside the warehouse. In addition, even when the outside temperature is negative, the air is pressurized so that positive temperature air is introduced into the refrigerator by the latent heat of condensation of the water in the fog curtain, so the initial cost and running cost are low. , stored items can be stored at low cost.
