Title:
HEAT MEDIUM
Document Type and Number:
WIPO Patent Application WO/2022/107185
Kind Code:
A1
Abstract:
This heat medium contains liquefied isobutane, liquefied propane, liquefied carbon dioxide, and liquid nitrogen. The content of the liquefied isobutane is 50-60 mass% relative to the total amount of the heat medium, the content of the liquefied propane is 5-15 mass% relative to the total amount of the heat medium, the content of the liquefied carbon dioxide is 20-40 mass% relative to the total amount of the heat medium, and the content of the liquid nitrogen is 5-15 mass% relative to the total amount of the heat medium. Because the liquefied isobutane and the liquefied propane, which are flammable, are mixed with the liquefied carbon dioxide and the liquid nitrogen, which are non-flammable, the heat medium is non-flammable. The heat medium does not contain chlorine or fluorine, and therefore has a low environmental burden.
