Scheduling defrost events and linking refrigeration circuits in a refrigeration system

A method of scheduling defrost events for a refrigeration system, comprising:

• receiving, by a computing device, a number of defrost events per day for a refrigeration circuit, a duration for each of the number of defrost events, a single start time value that is a start time for an initial one of the number of defrost events, and a maximum number of concurrent defrost events for the refrigeration system, wherein the maximum number of concurrent defrost events for the refrigeration system is at least two, and wherein a defrost event for the refrigeration system corresponds to a time between starting and stopping a defrost of the refrigeration system;
• determining, by the computing device, a defrost event schedule for the refrigeration circuit based on the number of defrost events per day, the duration for each of the number of defrost events, the single start time value that is the start time for the initial one of the number of defrost events, and the maximum number of concurrent defrost events;
• receiving, by the computing device, an adjustment to the determined defrost event schedule;
• updating, by the computing device, the defrost event schedule based on the adjustment;
• and
• executing, by an additional computing device, defrost events in the refrigeration system in accordance with the updated defrost event schedule.
