Tube-sheet heat exchange underground cooling granary

Abstract

The invention provides a tube-sheet heat exchange underground cooling granary. The internal surface of the granary is provided with a wall protection boundary surface; a protection layer or a function layer such as a wooden floor can be added on the wall protection boundary surface of the ground to fulfill a required function. The tube-sheet heat exchange underground cooling granary is characterized in that the wall protection boundary surface is hermetically connected with the internal surface of a building to form more than one closed space; each closed space is connected with a negative pressure source; a heat exchange boundary surface is arranged in or at the surface of a wall body of the tube-sheet heat exchange underground cooling granary, in the tube-sheet heat exchange underground cooling granary, or on the periphery within 5 meters of the tube-sheet heat exchange underground cooling granary and cooling heat exchange devices are installed and connected to the heat exchange boundary surface; the cooling heat exchange devices include pipe heat exchange devices and tube-sheet heat exchange devices. The temperature of stored objects in the underground cooling granary in the Yangtze River delta area is not greater than 8 DEG C in the first summer and the energy consumption is slight; it is hopeful that the storage time of rice extends from current two years to eight years.

Description

technical field [0001] The invention relates to a tube-sheet heat exchange cooling granary. Background technique [0002] Existing grain warehouses are mostly built on the ground for moisture-proof purposes. In the Yangtze River Delta region, in summer, due to sunlight and far-infrared radiation from ground objects, the temperature of grain in the warehouse gradually rises to 30°C or even higher. Even if a lot of money is spent on installing air conditioners to cool down, due to the poor thermal conductivity of grains, it is difficult to cool down the inventory evenly, resulting in huge investment but little effect. After a summer, the free fatty acid parameters of rice have changed greatly, and the nutrition and taste have obviously deteriorated, and many of them are directly treated as aged grains. There have also been cases where grains were hydrolyzed and rotted due to the formation of condensation when the temperature of grains at higher temperatures suddenly dropped....

Problems solved by technology

However, some existing underground structures, including the basement of residential buildings, have not solved the problem of water seepage or high humidity in the wall, which affects the use
