Title:
SHELTER COOLING DEVICE
Document Type and Number:
Japanese Patent JP2019100549
Kind Code:
A
Abstract:
To provide an inexpensive and simple cooling device that can stably cool an internal space of a shelter for a long time.SOLUTION: A shelter cooling device 1 comprises a tank 2 for storing liquefied carbon dioxide L and pressurized carbon dioxide gas LA, a pressure reducing valve 3 connected to the tank 2, a heat exchange tube 4 provided in an internal space A1 of a shelter and connected to the pressure reducing valve 3, and a discharge pipe 6 provided in a heat insulating space A3 and connected to a heat exchange device. The heat insulating space A3 is formed by an outer wall 7 and a protective wall 8, and internally filled with water W. When the pressure reducing valve 3 is opened, the carbon dioxide gas LA is injected from the pressure reducing valve 3, and temperature is decreased by adiabatic expansion effect. It is released to an external space A2 from an exhaust valve 84 via the heat exchange tube 4, the discharge pipe 6, the heat insulating space A3, etc. The internal space A1 is cooled by heat exchange in this passage process.SELECTED DRAWING: Figure 3
