Abstract
A refrigeration system includes a refrigerant circuit with a plurality of evaporator paths and a distributor for distributing refrigerant. The distributor includes a housing and a controllable valve for each evaporator path. The refrigeration system is operated by using a distributor including a magnet arrangement for controlling the valves.
Claims10
A refrigeration system with a refrigerant circuit comprising:
- a plurality of evaporation paths;
- a distributor causing a distribution of refrigerant, the distributor comprising a plurality of controllable valves and a housing, each of the plurality of controllable valves corresponding to one of the plurality of evaporation paths;
- wherein the distributor comprises a magnet arrangement controlling the plurality of controllable valves, the magnet arrangement comprising a rotor that carries at least one magnet;
- wherein each of the plurality of controllable valves is a pilot-controlled valve comprising:
- a corresponding auxiliary valve element that is moved by the at least one magnet, the auxiliary valve element blocking or releasing a passage from a pressure chamber to an outlet opening connected to at least one of the plurality of evaporation paths;
- and
- a corresponding main valve element that is moved by the refrigerant and interacts with a main valve seat, a side of the main valve element, which faces away from the main valve seat, bordering the pressure chamber.
