によりかなり高いものになつてしまう。 Conventionally known low-temperature warehouses have a structure in which storage temperature and humidity are controlled by a refrigerator and a humidifier. Therefore, the cost of storing stored items in this low-temperature warehouse becomes quite high due to the amortization of the capital investment (initial cost) and the running cost during storage.

るようにしたものである。 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 and running costs. Utilizing the difference between the temperature and humidity of the stored items and the outside temperature and humidity, by installing a simple automatic opening/closing curtain, we can promote ventilation and cold storage inside the tunnel (inside the warehouse) and keep the inside of the warehouse at the optimal temperature and humidity for stored items for a long period of time. It was designed to be retained.

開放するように設定されている。 The present invention will be explained below with reference to the drawings. Reference numeral 1 in the figure indicates an abandoned road tunnel. Shutters (automatically opening/closing curtains) 2a, 2b are attached to both entrances 1a, 1b of this tunnel 1, so that the inside of the abandoned road tunnel 1 between these shutters 2a, 2b is used as a low temperature warehouse according to the present invention. Temperature and humidity sensors 3a and 3b are installed inside these shutters 2a and 2b.
These temperature and humidity sensors 3a and 3b output a sensing signal when, for example, either the temperature or the humidity inside the tunnel 1 (inside the warehouse) falls outside the optimal temperature and humidity range for preserving the stored items 4 stored in the warehouse. The signals are set to be emitted and supplied to the shutters 2a and 2b, respectively. The shutters 2a, 2b close the inlets 1a, 1b when receiving the sensing signal, and open the inlets 1a, 1b at other times, that is, when the temperature and humidity inside the refrigerator are within the optimum temperature and humidity range. is set to.

費で設置することができる。 In the above configuration, the interior of the abandoned road tunnel 1 is normally in a constant temperature and humidity state with little fluctuation throughout the year. Therefore, if the inside of the refrigerator is within the optimum temperature and humidity range,
The interior of the refrigerator can be ventilated by opening the entrances 1a and 1b. On the other hand, if the outside of the abandoned road tunnel 1 deviates from the optimum temperature and humidity range, the ventilation with the outside air will reduce either the humidity or the temperature inside the refrigerator. When the temperature and humidity deviate from the optimum temperature and humidity range, the inlets 1a and 1b are closed to avoid being affected by outside air, and the temperature and humidity inside the refrigerator is returned to the optimum temperature and humidity range using the temperature and humidity stored on the walls inside the refrigerator. I can do it. Therefore, in this energy-saving low-temperature warehouse, if the storage material 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 storage can be carried out at a low running cost by only operating the shutters 2a and 2b. Furthermore, since this low-temperature warehouse can be completed by simply installing shutters 2a, 2b and temperature and humidity sensors 3a, 3b, it can be installed at about 1/10 the construction cost compared to conventional low-temperature warehouses.

Kosaka Tunnel on the old national highway in Kumano City (approximately 318m long)
Shutters and temperature/humidity sensors are installed at both entrances of the chamber, and 350 tons of evening fruits are stored inside the chamber.
Storage began in January 1981.
熊野市では、12月〜１月には外気温が−５〜−

そこで、シヤツターを手動にて開けはなしたとこ
ろ、庫内は−２℃、40％RHに下がつてしまい、
温湿度センサーとこのセンサーによつて制御され
るシヤツターの効果の大きいことが確認された。 In Kumano City, the outside temperature ranges from -5 to - from December to January.
There was a day when the temperature reached 10℃, but the temperature inside the refrigerator was 3-5℃.
Humidity was maintained constant at 85-95% RH, which was optimal for late fruit storage conditions (3-13°C, 85-95% RH).
When I opened the shutter manually, the temperature inside the refrigerator dropped to -2℃ and 40%RH.
It was confirmed that the temperature and humidity sensor and the shutter controlled by this sensor are highly effective.
この実施例に対し、近隣の鉱山跡地でセンサー

たところ、その15％が低温障害により腐敗してし
まつた。 In contrast to this example, when we stored late citrus fruits at a nearby mine site without installing sensors or shutters, 15% of them rotted due to low temperature damage.

安価に行うことができる。 As explained above, the energy-saving low-temperature warehouse according to the present invention provides automatically opening/closing curtains at both entrances of a tunnel such as an abandoned tunnel, and by partitioning the inside of the tunnel with these curtains, a warehouse is constructed within the tunnel. Temperature and humidity sensors are installed inside both entrances of the warehouse to issue a sensing signal when the temperature or humidity in the warehouse falls outside the range of temperature and humidity suitable for storing stored items stored in the warehouse, and furthermore, the automatic opening/closing curtain is installed. The structure is such that both entrances to the warehouse are closed only when receiving a sensing signal from the temperature/humidity sensor, and both entrances are opened at other times, thereby maintaining stable temperature/humidity inside the tunnel and outside temperature. Utilizing the difference in humidity, when the temperature and humidity inside the tunnel falls within the optimum temperature and humidity range for storage, the automatic opening/closing curtain is opened to promote ventilation and cold storage inside the tunnel (inside the warehouse), and to keep the inside of the warehouse warm. It is designed to keep stored items at the optimum temperature and humidity for a long period of time. Therefore, unlike conventional low-temperature warehouses, there is no need to use a refrigerator or humidifier to control the temperature and humidity inside the warehouse, and the initial cost and running cost of low-temperature warehouses are low, allowing stored items to be stored at low cost. I can do it.
