Description

  The present invention relates to a mobile ice room that can use natural ice frozen in winter in a cold region not only in a cold region but also in cooling and refrigeration in summer other than the cold region, and a method of using the mobile ice chamber.

Currently, energy consumption is rapidly increasing in the world, and global warming is accelerating. Countermeasures against global warming are required in each country, and especially in developed countries, energy consumption is intense, and it is necessary to take measures.
Further, in order to prevent global warming, an alternative energy that does not emit CO ₂ in place of fossil fuel is demanded.
Japan has advanced energy conservation measures and has become an advanced country for energy conservation. However, overall energy demand continues to grow, and further measures are required.

As one of the countermeasures, for example, the effect of suppressing global warming can be expected by reducing energy consumption used for cooling in summer.
Therefore, energy consumption can be reduced by using, for example, natural ice in winter in cold regions for air conditioning in the summer, but since long ago, natural ice in ponds and swamps was cut out to create cave and It has been practiced to insulate the basement with sawdust, rice husks, etc., store it until the warm season, take it out and use it for cooling the room or refrigeration of food.
Recently, natural ice in a pond is cut out and stored in an insulated warehouse, and vegetables and fruits are stored by latent heat when the ice melts, or ice cut from the pond is transported to a remote place.
Although global warming is currently progressing, it is possible to make natural ice anywhere in the highlands of Honshu and Hokkaido during the winter season.

As this type of prior document, for example, there is Patent Document 1, which includes storing snow falling in winter and ice made by natural freezing in an ice storage room until the summer, and in the summer from the ice storage room. A heat storage / heat exchange system is described that is transported to a heat storage tank and melted in the heat storage tank and its peripheral devices in accordance with the demand for cooling and refrigeration.
JP-A-7-305873

As described above, natural ice in ponds and swamps is cut out and stored until the warm season, and this is used for room cooling and food refrigeration.
Also, ice cut from the pond is transported to remote areas.
However, in that case, the work for cutting out ice from a pond or swamp and the work for storing ice are extremely difficult, and the work for cutting out in cold air is extremely difficult. However, it was not easy.
Moreover, since patent document 1 installs an ice storage room in the ground etc. and is not a portable thing, it is not assumed transporting and using an ice storage room to the distant area.

  In view of the above situation, the present invention provides a mobile ice room that can be easily used for cooling and refrigeration of natural ice frozen in the winter in cold regions, not only in cold regions, but also in summer seasons other than cold regions. The purpose is to provide a method of use.

In order to solve the above problems, the present invention provides the following configurations.
The invention according to claim 1 is a transportable mobile ice chamber provided with a container that is thermally insulated as a whole and a water tank unit installed in the container,
The container is provided with a door at the front end so that it can be opened and closed, an air inlet is provided at the top of the front end, a damper is provided at the top of the rear end, and a plug for connecting the duct is provided at the bottom of the rear end. The water tank section includes a plurality of water tanks that can be loaded in a plurality of stages, the water tank includes a top plate that covers an upper end, and a water inlet is provided in the top plate. A mobile ice chamber is provided.

The invention according to claim 2 is the method of using the mobile ice chamber according to claim 1, wherein in winter, water is poured into the plurality of water tanks, the door portion and the damper are opened, and the door is opened. Cool air outside the unit is introduced into the container, exhausted from the damper, and the water in the plurality of water tanks is iced.After ice making, the door and the damper are closed and the container is sealed. Save until summer,
In the summer, a duct is connected to the plug, the duct is connected to a facility for using cold heat, the inlet is opened, and the cold in the container is blown to the facility for using cold through a blower provided in the duct. The present invention provides a method for using a mobile ice chamber.

  According to a third aspect of the present invention, after the water in the plurality of water tanks is made into ice, the door is closed, the container is sealed and stored, and the cold-use facility is installed from the place where the ice is made. 3.
