Abstract

A method of mitigating refrigerant leaks within a refrigeration system that includes: detecting a leak of a refrigerant from a refrigeration system; closing a first valve to inhibit a fluid flow of the refrigerant between an evaporator and a condenser fluidly connected to the evaporator; and operating a compressor to direct another fluid flow of the refrigerant from the evaporator to the compressor.
