ABSTRACT:
A new method and apparatus are provided for sensing refrigerant temperatures in refrigerator systems, and for preventing underloading of the coil, or of any of the coils in a plurality of refrigerator evaporator circuit coils connected in parallel. The usual thermostatically controlled refrigerant flow control valve is controlled by a thermostatic sensor to ensure a predetermined minimum amount of superheat, usually about 5.5.degree. C. (10.degree. F.). To avoid underloading the refrigerant is rendered thoroughly turbulent and mixed, and in the multi-coil evaporator the flows from all of the coils are similarly thoroughly turbulated and mixed, by a turbulating and/or mixing device that intercepts the entire refrigerant flow just before the sensing of the superheat, thus ensuring that the temperature is accurately measured; in the multi-circuit coil system the device averages the temperatures of all the flows. Different turbulator/mixer devices are described and two or more such devices may be used in series. The superheat can now be reduced to about 2.degree. C. (4.degree. F.), the efficiency is increased, and close matching between valve size and coil loading is no longer required.
