Abstract
An apparatus for optimizing an efficiency of a refrigeration system, comprising means for measuring a refrigeration efficiency of an operating refrigeration system: means for altering a process variable of the refrigeration system during efficiency measurement: and a processor for calculating a process variable level which achieves an optimum efficiency. The process variables may include refrigerant charge and refrigerant oil concentration in evaporator.
Claims21
A method for improving efficiency of a set of operating conditions of an evaporator, the set of operating conditions comprising at least a ratio of at least one volatile refrigerant and at least one non-volatile component, comprising determining, a cost of operation under a plurality of sets of operating conditions;
- determining a cost of altering the set of operating conditions from an initial state to a target state;
- determining a cost effectiveness of an alteration in operating conditions from an initial state to a target state;
- and outputting an optimal target state based on an initial state and the cost effectiveness determination.
An apparatus for improving operating efficiency of an evaporator having a set of operating conditions comprising at least a ratio of at least one volatile refrigerant and at least one non-volatile component, comprising:
- an input for receiving information relating to a cost of operation, under a plurality of sets of operating conditions;
- a processor for:
- determining a cost of altering the set of operating conditions from an initial state to a target state and determining a cost effectiveness of an alteration in operating conditions from an initial state to a target state based on the input;
- and a memory for storing an optimal target state based on an initial state and the cost effectiveness determination.
