within the freezer compartment 12 of the refrigeration unit 14 to the alarm and alert features the present invention utilizes a temperature sensing bulb 28 interconnected to the housing 16 by an elongated flexible capillary tube 30 more specifically the housing 16 includes a selectively adjustable thermostat 32 that can be manually preset to various temperature set points such as for example in one design the set points denoted by the numbers 20 22 24 26 28 30 32 34 and 36 degrees the temperature sensing bulb 28 senses temperature changes and variations within the freezer compartment 12 and conveys these changes and variations to the thermostat 32 so that the thermostat 32 can register when the temperature within the freezer unit 14 rises and exceeds the given temperature set point value or temperature range when the thermostat 32 registers the temperature rise the normally open contacts or elements 34 of the thermostat 32 close thereby completing the circuit and initiating actions to be hereinafter described as shown in fig1 u2013 5 the freezer alarm system and apparatus 10 includes several signaling means that are actuated and powered for signaling the owner user that the temperature set point has been exceeded and remedial or corrective action is required thus mounted on the housing 16 is an audible buzzer alarm 36 for providing an audible alert to the owner user that the refrigeration unit 14 needs checked because the temperature within the freezer compartment 12 has surpassed the preset value the audible buzzer alarm 36 can include a volume control knob or dial that will be necessary if the freezer system and apparatus 10 includes remote alerts i e signaling means that are positioned.
