Abstract
A refrigeration system comprises a condenser, an evaporator, and a plurality of compressors in fluid communication. The plurality of compressors has a current run pattern with a current run capacity. The refrigeration system further comprises a controller operable to control the plurality of compressors. One method of operating the refrigeration system includes, at the controller, determining whether to increase or decrease the current run capacity and, when an increase or decrease in the current run capacity is required, creating a new run pattern to replace the current run pattern.
Claims15
A method of controlling a refrigeration system comprising
- a condenser, an evaporator, and a plurality of compressors in fluid communication, and
- a controller operable to control the plurality of compressors, the method comprising the acts of:
- at the controller,
- controlling the plurality of compressors with a current run pattern and resulting in a current run capacity;
- determining whether to increase or decrease the current run capacity;
- and
- when an increase or decrease in the current run capacity is required, creating a new run pattern to replace the current run pattern.
A method of controlling a refrigeration system comprising
- a condenser, an evaporator, and a plurality of compressors in fluid communication, and
- a controller operable to control the plurality of compressors, the method comprising the acts of:
- at the controller,
- controlling the plurality of compressors with a current run pattern and resulting in a current run capacity;
- determining a total capacity for the plurality of compressors;
- determining a percentage of the total capacity for each compressor;
- determining a next available run capacity percentage;
- and
- determining a new run pattern to replace the current run pattern, the new run pattern including the next available run capacity percentage.
