Claims (4)

The cold storage in the natural cold environment (outside air (temperature, wind speed) and sky radiation cooling) in the winter season is stored in a regenerator tube, and the cold is used as a cold heat source for seasonal cold storage in the warm season (spring, summer, autumn). A system comprising a regenerator tube / tank (hereinafter referred to as a regenerator tube), a cold collector and a circulating antifreeze liquid (hereinafter referred to as a refrigerant).
(1) Regenerator tube The regenerator tube is filled with a filler (capsule, etc.), and a liquid (hereinafter referred to as a regenerator material) that solidifies at a cold temperature obtained from the above-mentioned winter natural cold environment in the refrigerant is filled in the filler. It is full (slightly void). The space between the fillings is filled with the refrigerant.
The cold storage tube is placed in a cold storage, and cools the storage by absorbing the heat in the storage by natural convection and radiative cooling of the cold storage low temperature outer surface in the warm season.
In addition, this regenerator tube keeps the inside of the storage cabinet at high humidity by condensation on the outer surface of the regenerator tube at low temperature.
(2) Cold collector The cold collector is intended to absorb cold heat from the above-mentioned winter natural cold environment into the refrigerant. This cold collector has the following structure and arrangement in which the refrigerant flows into the pipes of the inclined multiple pipes and the cold heat absorption capacity per refrigerant volume is increased in each stage.
a) The cold collector is placed in the outdoor cold outdoor air, with the vertical axis on the sky side of the inclined surface of the cold collector facing north, and with the daytime solar radiation shielded.
b) The inclined multiple tube is a high heat emissivity surface (black or the like) tube or a transparent tube, and in the case of the transparent tube shown on the left, the refrigerant is a liquid having a high heat emissivity such as black.
c) In the warm season, the refrigerant is not circulated into the inclined multi-tubes.
(3) Refrigerant Refrigerant is an antifreeze liquid in the cold collector in the natural cold environment in winter, and circulates between the cold collector and the regenerator tube in winter and moves the cold to solidify the regenerator material in the regenerator tube filling. Let The regenerator tube according to claim 1, wherein the outer surface of the regenerator tube has antifungal and antifouling effects. The regenerator tube according to claim 1 or 2, wherein the regenerator tube is filled with two or more kinds of fillers having different sizes in order to increase a filling density of the filler in the regenerator tube. In the structure of the regenerator tube according to claim 1, claim 2, or claim 3 and installed indoors, the cold heat in the cold storage is absorbed from the outer surface of the regenerator tube during winter and the liquid in the filling has not solidified. A cold storage tube that keeps the temperature in the storage room in the winter higher than the temperature of the outside air by keeping it in the completed state, and used as a storage technology to prevent freezing damage in winter such as crops.
