Abstract
A method of operating a refrigeration system (20) includes operating the refrigeration system in refrigeration mode. A current access condition into a refrigerated cargo space (22) is detected. At least one heat exchanger (32) in the refrigerated cargo space (22) is directed into a defrost mode during the current access condition. The refrigeration system (20) is directed into a refrigeration mode when the current access condition is no longer detected.
Claims20
A method of operating a refrigeration system, the method comprising:
- operating the refrigeration system in refrigeration mode;
- detecting a current access condition into a refrigerated cargo space;
- in response to a detection of the current access condition, determining a length of time between a preceding defrost mode and the detection of the current access condition;
- directing at least one heat exchanger in the refrigerated cargo space into a defrost mode during the current access condition if the length of time is greater than a predetermined amount of time;
- and
- directing the refrigeration system into the refrigeration mode when the current access condition is no longer detected.
3 more elements
A controller for a refrigeration system comprising:
- a processor;
- and
- a memory comprising computer-executable instructions that, when executed by the processor, cause the processor to perform operations, the operations comprising:
- operating the refrigeration system in refrigeration mode;
- detecting a current access condition into a refrigerated cargo space;
- in response to a detection of the current access condition, determining a length of time between a preceding defrost mode and the detection of the current access condition;
- directing at least one heat exchanger in the refrigerated cargo space into a defrost mode during the current access condition if the length of time is greater than a predetermined amount of time;
- and
- directing the refrigeration system into the refrigeration mode when the current access condition is no longer detected.
