Beschreibung
Zusammenfassung:	A refrigeration system includes a compressor, condenser, separator, and evaporator. A condenser inlet is connected to an outlet of the compressor. A separator inlet is connected to an outlet of the condenser. An evaporator inlet is connected to a first outlet of the separator. An evaporator outlet is connected to the separator inlet. The refrigeration system includes a control unit having instructions stored thereon for executing a method comprising the steps of repetitively calculating a refrigeration load on the evaporator, and controlling a level target of refrigerant in the separator based on the calculation of the refrigeration load. In one configuration, the separator is positioned substantially laterally of the evaporator so that the refrigerant is gravity fed from the separator to the evaporator.
