Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to an energy-saving low-temperature warehouse that can be installed at low cost using a mine road such as a return tunnel 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 warming machine. Therefore, the cost of storing stored items in this low-temperature warehouse becomes high due to the amortization of the capital investment (initial cost) and the running cost during storage.

This invention was made in view of the above circumstances, and its purpose is to provide an energy-saving low-temperature warehouse with low initial construction and running costs. Utilizing the difference between the stable, constant temperature and humidity inside the warehouse and the outside temperature and humidity, we installed a simple automatic curtain that opens and closes automatically, promoting ventilation and cold storage inside the warehouse (inside the warehouse) and keeping the inside of the warehouse free of stored items. It is designed to maintain the optimum temperature and humidity for a long period of time.

The present invention will be explained below with reference to the drawings. Code 1 in the diagram
indicates the return tunnel. This tunnel has 10 cars with a population of 1a and lb with 2 shutters (automatic opening/closing curtains).
a%2b is attached. These shutters 2a
, 21) are equipped with temperature and humidity sensors 3a and 3b.

These temperature and humidity sensors 3a and 3b are connected to the tunnel 1, for example.
When either the temperature or the humidity inside the refrigerator falls outside the optimal temperature and humidity range for storing the stored items 4 in the refrigerator, a sensing signal is emitted, and the shutters 2a and 2b are activated, respectively.
is set to supply. The above shutter 2a
, 2b is supplied with the sensing signal to each population 1a.
, 1b are closed, and at other times, that is, when the temperature and humidity inside the refrigerator is within the optimum temperature and humidity range, each population 1a, 1b is opened.

According to the above configuration, if the inside of the refrigerator is within the optimum temperature and humidity range,
Inlets 1a and 1b can be opened to ventilate the inside of the refrigerator, and if either the temperature or humidity inside the refrigerator deviates from the optimum temperature and humidity, inlets 1a and 1b are closed at 9 o'clock to avoid being affected by outside air. The temperature and humidity inside the refrigerator can be returned to the optimum temperature and humidity range using the temperature and humidity stored on the walls of the refrigerator. Therefore, in this energy-saving low-temperature warehouse, if a stored item has an optimal storage temperature and humidity range within a range that can be controlled by the temperature and humidity of the inner wall surface of the tunnel 1, the stored item can be stored only by the operation of the shutter 2a12b. This can be done at low running costs. In addition, this low temperature warehouse has shutters 2a and 2b and temperature and humidity shutters 3a and 3bl! : Since it can be completed by simply installing a , it can be installed at about 1/1 degree of construction cost compared to conventional low-temperature warehouses.

Next, the present invention will be explained in more detail with reference to Examples.

〔Example〕

Shutters and temperature/humidity sensors were installed at both entrances of the Koita Tunnel (approximately 318-3 long) on the old national highway in Kumano City, and 350 tons of evening sweets were stored in the warehouse. Niji started.

In Kumano City, the outside temperature ranges from -5 to -10℃ from December to January.
The temperature inside the refrigerator will be 3-5℃ and the humidity will be 85-85℃.
It was maintained constant at 951RH, and the late citrus storage conditions (3-13
C, 85-95 RH1 was optimal. So, when I opened the shutter manually, the temperature inside the refrigerator was -2℃.
The temperature dropped to 40%RH, and it was confirmed that the temperature and humidity sensor and the shutter controlled by this sensor were highly effective.

In contrast to this example, when we stored late-citrus fruits at a nearby mine site without installing sensors or shutters, 15 tons of them rotted due to low-temperature damage.

As explained above, the energy-saving low-temperature warehouse according to the present invention uses a mine road such as a return tunnel, and utilizes the difference between the stable temperature and humidity inside the tunnel and the outside air humidity to enable easy automatic opening and closing. By attaching curtains, we promote ventilation and cold storage inside the tunnel (inside the warehouse) and maintain the optimum temperature and humidity inside the warehouse for a long period of time, so the initial cost and running cost are low. , it is possible to store stored items at low cost.

As claimed above, temperature and humidity sensors are installed inside both entrances of the caravan to detect the appropriate temperature and humidity for storage of stored items stored in the gap, and at both entrances of the carway, temperature and humidity sensors are installed based on the sensing signals of the temperature and humidity sensors. This is an energy-saving, low-wet warehouse that is equipped with self-defense 1 opening/closing curtains that open and close both entrances.
