A method of controlling a refrigeration system having a refrigerant disposed within a fluid-tight circulation loop with a compressor, a condenser and an evaporator, wherein the method includes the steps of (a) compressing refrigerant in a gaseous state within the compressor and cooling the refrigerant within the condenser to yield refrigerant in the liquefied state; (b) flowing refrigerant from the condenser into the evaporator, wherein the refrigerant partially exists in a two-phase state; (c) flowing refrigerant from the evaporator to the compressor; (d) repeating steps (a)-(c); (e) detecting the condition of the refrigerant with a sensor disposed within the evaporator upstream of the outlet opening; and (f) controlling the flow of refrigerant to the evaporator in step (b) based upon the detected condition.
