Title:
STRUCTURE FOR PREVENTING DAMAGE OF WATER SUPPLY PIPE IN FREEZING
Document Type and Number:
Japanese Patent JP2022024908
Kind Code:
A
Abstract:
To obtain a structure for preventing damage of a water supply pipe in freezing, which can prevent damage of a water supply pipe resulting from freezing of water.SOLUTION: A structure for preventing damage of a water supply pipe during freezing, is configured to comprise a water supply pipe 40 that cools a heat exchanger by supplying water from the outside, and a gas layer 50 that is provided at a portion of the water supply pipe 40 where water is frozen at the very end when water W inside the water supply pipe 40 is frozen. Consequently, the gas layer 50 finally absorbs the expansion of the volume of the water W during freezing, so that it is possible to prevent the water supply pipe 40 from being damaged resulting from the freezing of the water W.SELECTED DRAWING: Figure 2
