Abstract: A preheat damper preheats ambient air being directed to an air handling unit of a data center to mitigate ice accumulation caused by the ambient air. The ambient air can be preheated upstream of a mist eliminator, which removes moisture from the ambient air upstream of the air handling unit, to mitigate ice accumulation in the mist eliminator. The preheat damper directs exhaust air from an exhaust air plenum. The preheat damper can be adjusted based on the ambient temperature, and can be upstream of a return damper which directs exhaust air from the exhaust air plenum based on characteristics of the cooling air supplied to cool data center equipment. The return damper can be adjusted in counter-opposition with one or more intake dampers to maintain cooling air characteristics, and concurrently with the preheat damper to direct ambient air to the air handling unit through the exhaust air plenum.

Abstract: A guide groove is provided on both sides in a door width direction of a plate-like portion of a door. A radius of curvature of the plate-like portion in a single non-mounted state is set more than that of the guide groove, to thereby support both end portions in the door width direction of the plate-like portion respectively at three abutment points P1 to P3. A rib is provided in the plate-like portion to extend from one end portion in the door width direction of the plate-like portion to the other end portion thereof, so that force generated from both end portions in the door width direction of the plate-like portion is transferred to a center portion in the door width direction of the plate-like portion via the rib. Therefore, it can prevent the center portion and vicinity of the plate-like portion from being deformed in the direction away from a seal surface of the air conditioning case.

Abstract: In a central air-conditioning system and method, a distribution mechanism distributes warm air or cool air generated by an air-conditioning unit to a plurality of rooms in a house. A control device controls the distribution mechanism to adjust a temperature of each room. A plurality of room terminals are provided as a device each dedicated to a room. Each room terminal receives an input of a preset temperature for the room and detects temperature of the room, and outputs the received preset temperature and the detected room temperature to the control device. The control device judges whether or not a specified room terminal is mounted in a specified room, based on a transition of control of the distribution mechanism in the specified room and a change in the detected temperature. The control device stops air-conditioning the specified room when judged that the specified room terminal is not mounted in the specified room.

Abstract: A ventilating fan includes a sirocco fan disposed in a box-shaped body and an adapter connected to an air outlet of the sirocco fan.

Abstract: An aspirating induction nozzle is designed to ensure that the discharge velocity is always at or above the governing guidelines while simultaneously leveraging physics to consistently induce fresh air with no moving parts. To achieve this, the flow rate from the fan at the inlet of the nozzle must be accelerated. A frusto-conical transitional flow impinger provides a mechanism to effectively control the flow velocity in the region from the discharge of the fan impeller through the nozzle body. The addition of the impinger provides a mechanism to ensure that flow velocities are always constant or increasing until the discharge plane of the nozzle body, thereby offering a means to optimize the design of the nozzle for the given flow and/or operational pressure drop requirements, while sustaining a tuned venturi effect for steadfast operation in a dynamic environment.
