ABSTRACT:
A monitoring system is provided that is capable of determining when the temperature of at least one point along a refrigeration unit is not within a standard temperature range known for the operation of the refrigeration unit at the at least one point. In particular, the monitoring system is capable of alerting a technician or operator if, after a predetermined amount of time has elapsed after the refrigeration unit is expected to start, the temperature of the at least one point along the refrigeration unit is not within the standard temperature range known for operation of the refrigeration unit when the compressor is running. The predetermined elapsed time may be of a length of time necessary to allow for the refrigeration unit to complete a defrost and/or delog cycle and recover from such cycle. The monitoring of the at least one point along the system may be accomplished by the monitoring of a thermocouple. Further, the monitoring system may include sensors to monitor (i) when the door of the refrigeration compartment of the refrigeration unit is, or has been, open, as well as (ii) the temperature in the refrigeration compartment. In this regard, the monitoring system may alert a technician or operator when the temperature in the refrigerator is not optimal, taking into consideration whether the door of the refrigeration compartment has been, or is, open or closed and, optionally, also taken into consideration whether the refrigeration unit is operating properly.
