Abstract:
1. 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.
