Abstract
A vapor compression refrigeration system is which a self heated thermistor is located in the suction line downstream of the evaporator to directly sense the quality of the refrigerant flowing thereover. Appropriate circuitry measures the voltage drop across the thermistor and this drop is used to vary the duty cycle of the system's expansion valve thereby controlling the superheat of the evaporator.
