  • Patent number: 8770493
    Abstract: A system configured to provide cooling of electronic equipment in a shelter in combination with an air conditioning (A/C) system. The system includes one or more blowers for drawing air into the shelter, a damper arrangement for controlling air exhaust. The system further includes a DC powered controller coupled to the one or more blowers, the damper arrangement, and the A/C system. The controller is configured to receive at least a first analog input signal associated with a shelter-interior temperature, a second analog input signal associated with a shelter-exterior temperature, and a plurality of alarm input signals and to generate the one or more first control signals to control blower rotational speed, the second control signal to open/close the damper arrangement, and a third control signal to inhibit/activate the A/C system based on at least the first analog input signal, or the second analog input signal, or a plurality of alarm input signals, or a combination of these.

  • Patent number: 8493221
    Abstract: One embodiment involves detecting the fouling of an air filter used to filter airflow entering a computer system. An expected airflow rate is obtained from a current fan speed. An expected temperature rise between two positions is computed as a function of the expected airflow rate and the power consumption of heat-generating components, such as servers. An actual temperature rise is obtained from temperature sensors. An electronic alert is automatically generated in response to the actual temperature rise exceeding the expected temperature rise by a setpoint. Different setpoints may be used to trigger distinct electronic alerts.

  • Publication number: 20120318878
    Abstract: The controlling of a plurality of smoke and heat evacuation and ventilation (SHEV) devices is shown, in which the devices are connected to field wiring that also includes fire detection devices and alarms. A constant limited current (705) is supplied in a first direction for fire detection. A non-limited voltage is applied to supply alarm current 708 in a second direction for sounding alarms and opening the SHEV DEVICES. A non-limited positive voltage 712 is applied to supply reset current in the first direction for closing the SHEV devices.

  • Patent number: 7714731
    Abstract: A detection mechanism for monitoring airflow in an electronics enclosure includes a first thermal sensor positioned proximate the enclosure for measuring an ambient air temperature and a second thermal sensor positioned proximate an exit air stream for measuring the temperature of air that is heated by the electronics in the enclosure. A control circuit is coupled with the first and second thermal sensors and is configured for determining a temperature differential between the measured temperatures of the thermal sensors. The control circuit may initiate an alarm when the temperature differential exceeds a setpoint thereby indicating restricted airflow in the enclosure. The control circuit might also take other remedial steps prior to initiating the alarm.

  • Patent number: 7261243
    Abstract: A thermostat is provided that receives one or more inputs from at least one heating system of a climate control system, and initiates an appropriate action in response to the input. The thermostat can turn off a heat pump providing substandard heat and responsively turn on a fuel-fired auxiliary furnace. The thermostat may discontinue further operation of the auxiliary furnace upon receiving an operating error signal associated with the auxiliary furnace, and responsively turn on the heat pump to provide for continued heating. The thermostat may also discontinue operation of the fuel-fired furnace and turn on a circulating fan in response to an input signal indicating a furnace high-temperature or a carbon monoxide presence.
