EXPERIMENTAL STUDIES AND ESTIMATES OF THE EXPLOSION LIMIT OF SOME ENVIRONMENTALLY FRIENDLY REFRIGERANTS

ABSTRACT

This paper develops diagrams of the explosion limit of binary mixtures of R125 and one of six refrigerants based on experimental studies and proposes a mathematical model to calculate the concentration and the explosion limit of a tricomponent mixture containing one nonflammable component. The explosion limit of the mixtures can be estimated by using these diagrams.

Keywords:

• alternatives
• explosion limit
• flammability
• refrigerants
