Classification: CPC F | IPC F

Claim 13:
14. A refrigeration system, comprising:
a variable speed compressor;
a first evaporator;
a second evaporator operably coupled in series with the first evaporator;
a first valve coupled to the variable speed compressor and the first evaporator;
a second valve fluidly coupled to the second evaporator and operable in a partially open state;
a pressure regulator directly coupled to the second valve via a single conduit;
a thermal exchange media that changes between a gaseous state and a liquid state as the thermal exchange media is recirculated sequentially and in series through each of the variable speed compressor, the first valve, the first evaporator, the pressure regulator, the second valve and the second evaporator; and
a controller communicatively coupled to the second valve and configured to selectively open the second valve based on a percentage of thermal exchange media in the liquid state and the gaseous state entering the second valve from the pressure regulator, wherein the pressure regulator is a flash chamber configured to separate the thermal exchange media in the gaseous state from the thermal exchange media in the liquid state.
