Method for early detection of cooling-loss events

A system for early detection of a cooling-loss event, the system comprising:

• an enclosure to define a given space in which multiple temperature sensitive devices are stored to detect an air temperature in the given space;
• a relative humidity sensor operably disposed in the given space;
• an early detection apparatus including an alarm system disposed in signal communication with the relative humidity sensor,
• the early detection apparatus being configured to initiate the alarm system to generate an alarm of a cooling loss event prior to the multiple temperature sensitive devices sensing effects of the cooling loss event in accordance with the relative humidity sensor sensing that a change in a relative humidity in the given space exceeds a defined change threshold for the given space in a period of time that is shorter than a period of time required for the multiple temperature sensitive devices to sense the effects of the cooling loss event;
• and
• a temperature sensor to sense a temperature of the given space,
• wherein the early detection apparatus comprises a warning system and is configured to generate a warning in an event the relative humidity sensor senses that relative humidity in the given space is outside a defined relative humidity limit or the temperature sensor senses that a temperature of the given space is outside a defined temperature limit.
