ABSTRACT: In this study, we analyze factors affecting
the explosion limits of flammable refrigerants. We conclude that any method
used for measuring flammable refrigerant explosion limits has its conditional
restrictions. Flammable refrigerants in the atmosphere can also explode under
certain conditions, when the concentration is approaching the explosion limits.
An experimental study on the explosion limits of six kinds of flammable
refrigerants is carried out with a mixture of refrigerant and combustible
refrigerant, which has a similar effect to a flame retardant. An experimental
apparatus was designed to test the explosion limits of mixtures made from three
different nonflammable refrigerants and six different flammable refrigerants.
Two practical models were developed to estimate the critical concentration for
inhibiting explosion of refrigerant mixtures: one was made up of two flammable
components with one nonflammable component, and the second was made up of one
flammable component with two nonflammable components.
