WORKING SUBSTANCE PAIR FOR ABSORPTIVE HEAT CIRCULATION SYSTEM WITH HEAT SOURCE TEMPERATURE BETWEEN 60°C AND 130°C

摘要

Provided is a working substance pair for an absorptive heat circulation system with a heat source temperature between 60°C and 130°C. The working substance pair consists of a working substance and an absorbing substance. The working substance is selected from one or a mixture of more than two of fluoroalkanes, fluoro-olefins, fluoroethers, non-substituted alkanes, or olefins. The absorbing substance is a liquid mixture composed of an ionic liquid of 1%-50% by mass and an organic liquid of 50%-99% by mass. The working substance is miscible with the absorbing substance at a temperature of 20°C to 80°C. The working substance pair overcomes some defects of a conventional working substance pair and has the features of being non-toxic, safe, environmentally friendly and so on.
