Patent number: 11324145Abstract: An environmental control system for a telecom shelter integrates with a native HVAC system for exchanging interior air in a conditioned space in a machine room, telecom enclosure, or other closed machine environment by forcing or directing cooler outside air to replace interior air without active refrigeration by the native HVAC system. Primary cooling and heating of the conditioned space in the enclosure is performed by an exchange system and control logic that identifies, based on sensory input, when outside air exchange is more efficient than native AC (Air Conditioner) operation. The native AC system is suppressed or inhibited, and primary environmental control performed by fan driven exchange of outside air with air in the enclosure.Type: GrantFiled: May 21, 2019Date of Patent: May 3, 2022Assignee: Schroff Technologies International, Inc.Inventors: Richard De Felice, David Therrien, Robert Paterson, Henry Riddoch

Publication number: 20210310680Abstract: A control system for ambient air exchange with a machine room or similar enclosure controls an exchange rate of the ambient air based on a temperature differential between the inside (machine room) and outside temperatures, rather than absolute thermostatic controls based solely on the interior temperature. A larger temperature difference between the inside and outside air means a greater cooling potential for the exchanged air. Ambient air exchange is performed by dampers/louvers/vents and a fan speed driving the air exchange. Control of the fan speed based on the temperature differential allows lower fan speeds for controlling the temperature when the temperature differential indicates ample cooling. Higher fan speeds, incurring additional electrical consumption and fan noise, are only needed when a relatively small differential limits the cooling ability of the exchanged air.Type: ApplicationFiled: March 31, 2021Publication date: October 7, 2021Inventors: Christophe Massenet, Richard De Felice, David Therrien, Robert Paterson

Patent number: 8770493Abstract: 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.Type: GrantFiled: October 10, 2012Date of Patent: July 8, 2014Assignee: Minebea Co., Ltd.Inventors: David Therrien, Henry Riddoch
