Assignee: WHIRLPOOL CORPORATION
Field: Thermal processes and apparatus (Mechanical engineering)
Classification: CPC F | IPC F

Claim 7:
8. A refrigeration system for an appliance, comprising:
a compressor;
a first evaporator;
a second evaporator operably coupled to the first evaporator;
a thermal exchange media that changes between a gaseous state and a liquid state;
an electronic expansion valve configured to selectively regulate the thermal exchange media from the first evaporator into the second evaporator and operable in at least a partially open state, wherein the electronic expansion valve regulates a pressure drop based on a percentage of the thermal exchange media in the liquid state and the gaseous state entering the electronic expansion valve in the liquid state and the gaseous state;
a pressure regulator operably coupled to the electronic expansion valve via a single conduit and operably coupled to the first evaporator, 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, wherein the pressure regulator directs the thermal exchange media in the gaseous state and the liquid state to the electronic expansion valve, wherein the flash chamber is operably coupled in series with the first evaporator and the electronic expansion valve; and
a controller configured to control the electronic expansion valve, wherein all of the thermal exchange media is recirculated sequentially, and in series, through each of the compressor, the first evaporator, the pressure regulator, the electronic expansion valve and the second evaporator.
