Description

[Detailed Description of the Invention] This invention has low installation cost (initial cost).
Moreover, it relates to an energy-saving low-temperature warehouse that does not require running costs.

Conventional low-temperature warehouses are built above ground with refrigerators and humidifiers.
Since the refrigerator and humidifier are used to control the temperature and humidity inside the refrigerator at a desired level, both the initial cost and the running cost are high. In addition, in such low-temperature warehouses, it is generally necessary to use a high level of technology to control the inside of the warehouse to a low temperature and high humidity that is optimal for storing late fruit, etc., so a solution to this point is also desired.・Ru.

This invention was made in view of the above circumstances, and its purpose is to provide a low-temperature warehouse with low initial and running costs.The purpose of this invention is to provide a low-temperature warehouse with low initial and running costs. , Ventilation holes of different heights are provided at the #1 location, and when the temperature of this storage area becomes higher than the outside temperature, ventilation occurs naturally due to the difference in specific gravity of the atmosphere, and the outside cold heat is introduced into the room. be.

The present invention will be explained below with reference to the drawings. The figure shows one embodiment of the present invention, and reference numeral 1 in the figure indicates a space within the rock mass, which is referred to as a storage area.

Ventilation holes 2.3 having different opening heights are bored in this rock interior space l.

In the above configuration, as is well known, the rock interior space 1 is kept at a constant low temperature throughout the year6, so in winter, the temperature of the rock interior space (inside the warehouse) 1 becomes higher than the outside temperature, and due to the difference in specific gravity, The air inside the refrigerator is exhausted through the ventilation hole 3, and the cold air from outside enters the inside 1 through the ventilation hole 2, which has a low opening position.

Therefore, in winter, ventilation of the interior 1 of the refrigerator is promoted, and outside cold heat is stored in the rock of the interior 1 of the refrigerator. In this way, the cold energy stored in the bedrock during the winter naturally keeps the temperature inside the refrigerator 1 low even in the spring or summer.Moreover, in the spring or summer, the outside temperature is higher and the lower temperature of the interior 1 is lowered. Since the specific gravity is higher and no ventilation occurs, the temperature inside the refrigerator 1 is maintained at a low temperature for a long period of time. In addition, as in Shuhei, the space 1 inside the bedrock is always kept at high humidity due to the moisture content of the bedrock, so even if outside air with a minus temperature enters the inside 1 in the winter, the inside 1 will remain above the above level. The temperature does not become negative due to the release of the latent heat of condensation of water. Therefore, this low-temperature warehouse inside the bedrock is
It is ideal for storing late citrus fruits, which require low temperatures during storage, but would otherwise suffer from low-temperature damage at sub-zero temperatures. Furthermore, the initial cost of this in-bedrock warehouse is low, as it only requires the cost of drilling ventilation holes 2.3.
Thereafter, the interior of the refrigerator is maintained at a low temperature and high humidity due to natural temperature changes, so no running costs are required.

As explained above, the energy-saving in-base warehouse according to the present invention uses the low-temperature and high-humidity space in the bedrock as the storage location,
A high-pitched ventilation hole is installed in this storage area, and when the temperature of this storage area becomes higher than the outside air temperature, the air will naturally become overheated due to the difference in atmospheric pressure, and the outside cold and heat will be introduced into the interior. Since the initial cost is less than lfk, storage can be carried out without any running cost.
