Expansion valve and throttle valve

The expansion valve is the cut-off point between high and low pressure sections in the refrigerant circuit. Assembled in front of the evaporator. For reaching the optimal refrigerant flow in the evaporator, the refrigerant flow is controlled via the expansion valve irrespective of temperature. This ensures the complete evaporation of the fluid refrigerant so that only gaseous refrigerants reach the compressor. Expansion valves can differ from each other in design.
