Title:
REFRIGERANT FOR REFRIGERATOR
Document Type and Number:
Japanese Patent JPH0617040
Kind Code:
A
Abstract:
PURPOSE: To obtain economically a refrigerant for a refrigerator having a refrigerative capacity superior to that of a fluorocarbon refrigerant, dispensing with high pressure and being free from the problem in flammability by mixing propane with a specified gas in a specified ratio.
CONSTITUTION: The refrigerant is prepared by mixing propane with liquefied carbon dioxide in an amount to give an ignitability limit value or larger, desirably in a mixing ratio of the propane to the liquefied carbon dioxide in the liquid phase of 8:2-6:4 (by mole). Namely, propane is used as the principal component to be mixed with liquefied carbon dioxide in an amount to give a concentration in the liquid phase of 30-35mol%.
