ABSTRACT:
Refrigeration apparatus comprising a refrigerant compressor, a condenser, an evaporator, a suction line connecting said evaporator to the intake of the compressor, and a capillary tube restrictor effective to feed refrigerant from the condenser to the evaporator. Refrigerant flow control means is interposed the capillary tube and the evaporator, with a portion of the flow control means disposed in heat exchange relation with the evaporator outlet. The flow control means further includes a diverter conduit for a portion of the liquid refrigerant being fed to the evaporator and affording heat exchange of said portion with refrigerant flowing from the condenser to the evaporator.
In operation, an increase in superheat sensed by the control means through its heat exchange relation with the evaporator outlet - an indication of a starved evaporator - will cause the control means to effect liquid refrigerant flow through the diverter conduit, where it will operate by way of the described heat exchange to subcool liquid refrigerant flowing through the capillary tube restrictor from the condenser to the evaporator, thereby increasing the refrigerant mass-flow rate and restoring the evaporator to its non-starved operating condition.
