Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a low temperature warehouse with low installation costs and low running costs.

Conventional low-temperature warehouses are configured to maintain the interior of the warehouse at a constant temperature using refrigerators. Therefore, this low-temperature warehouse has high equipment costs (initial costs) and high running costs.

This invention was made in view of the above circumstances, and its purpose is to provide a low-temperature warehouse with low initial cost and running cost. It uses the cold energy from the outside air to create ice in an ice-making bit installed inside the refrigerator, and this ice keeps the temperature inside the refrigerator at a low temperature.

The present invention will be explained below with reference to the drawings. FIG. 1 shows a first embodiment of the invention, in which the invention is applied to an above-ground warehouse. 1 in the diagram is a warehouse (ground building)
An ice making bit 3 is provided on the floor 2 of this warehouse 1. A heat pipe 4 is installed in the warehouse 1 with one end inserted into the ice making bit 3 and the other end protruding into the outside air on the roof. This heat pipe 4 is configured so that the working fluid moves inside only when the outside air is cold at a low temperature, so the cold heat of the outside air is transmitted to the ice making bit 3 only in winter, and the outside air in spring or summer is transferred to the ice making bit 3. This means that the hot air will not be transmitted to ice making bit 3.

Therefore, ice is made using the cold air outside in the winter, and the inside of the refrigerator can be cooled with this ice, and the refrigerator is not affected by the hot air outside in the spring or summer. In addition, since the inside of the refrigerator is cooled in winter by making ice as described above, the temperature never becomes negative. Therefore, although this ice-temperature storage needs to be kept at a low temperature during storage,
It is ideal for storing late citrus fruits, which can suffer from low temperature damage at negative temperatures. Further, the initial cost of this ice temperature storage is only the installation cost of the ice making bit 3 and the heat pipe 4, so it is inexpensive and does not require any running cost.

FIG. 2 shows a second embodiment of the present invention, in which the present invention is applied to an underground warehouse using a return tunnel or the like. In the figure, reference numeral 5 indicates an underground space such as an underground tunnel or a return tunnel. An ice-making bit 7 is provided on the floor 6 of this underground space 5. In this underground space 5, a heat pipe 8 having the same structure as the heat pipe 4 is provided.
However, while inserting one end of it into the ice making bit 6,
It is fitted with the other end protruding into the atmosphere above the ground.

Even if the present invention is configured as described above, the same effects as in the first embodiment can be obtained. Moreover, in this second embodiment, the advantage of the underground warehouse, that is, the advantage that a constant low temperature and high humidity environment can be naturally obtained without any initial cost, further enhances the effects of the present invention. That will happen.

As explained above, the energy-saving ice-temperature storage according to the present invention utilizes the low temperature of the outside air in winter by using a heat pipe (heat siphon), and uses the cold energy of the outside air to store the storage. By forming ice on the ice-making bit installed inside the refrigerator, the ice is used to maintain the temperature inside the refrigerator at a low temperature, which can significantly reduce initial costs and running costs.
