  • Patent number: 11375640
    Abstract: A data cabinet is disclosed, having a cabinet body for enclosing one or more rack-mounted units, the cabinet body having an inlet for allowing a cooling medium to enter the cabinet and an outlet for allowing the cooling medium to exit the cabinet, a rack for supporting the one or more rack-mounted units within the cabinet body, and one or more sealing members. The rack and the cabinet body define a first plenum space in fluid communication with the inlet and a second plenum space in fluid communication with the outlet. The sealing members substantially block the cooling medium from flowing between the first and second plenum spaces, whilst permitting the cooling medium to flow from the first plenum space to the second plenum space through the one or more rack-mounted units. This arrangement can improve the cooling efficiency, by increasing the flow rate through the rack-mounted units.

  • Patent number: 10562369
    Abstract: A system includes a power source, a sensor to detect data, and a HVAC system having a compressor to compress vapor refrigerant and a fan to blow conditioned air into a cabin of the vehicle, the compressor and the fan both designed to operate using a portion of the power generated by the power source. The system further includes an ECU to predict that the vehicle will accelerate or decelerate based on the data, to decrease power provided to the compressor and increase power provided to the fan when the ECU predicts the acceleration in order to reduce total power provided to the HVAC system and to reduce variance in total noise and vibration generated by the HVAC system, and to increase power to the compressor when the ECU predicts that the vehicle will decelerate in order to increase the total power provided to the HVAC system.

  • Patent number: 10495339
    Abstract: A method of providing ventilation for an enclosed space includes detecting, by a controller including one or more processing devices, an operation of a door to the enclosed space in response to receiving a first signal indicative of an electrical characteristic of a motor that operates the door to the enclosed space. The method further includes generating, by the controller responsive to detecting the operation of the door, a control signal configured to operate a ventilation system to exhaust air from within the enclosed space to an environment outside of the enclosed space. The method also includes transmitting the control signal to cause an activation of the ventilation system.

  • Patent number: 10488083
    Abstract: A variable refrigerant package air conditioner is shown that is easy to install in new construction with a unique base that causes collected mixture that overflows to drain outside the building. A control system is shown that has motors and compressor that are pulse width modulated so the air conditioner is infinitely variable while maintaining the highest possible power factor. Dehumidification of outside air occurs as it is mixed with inside air. By gradually approaching a temperature set point and even reheating after dehumidification, moisture is removed from the room.

  • Patent number: 10461381
    Abstract: A battery cooling apparatus includes a case for housing battery cells and a fan device disposed in the case for blowing air through a circulation passage to cool the battery cells. The case includes a discharge passage which makes communication between inside and outside of the case to allow part of the air circulating through the circulation passage to leak to outside the case. The fan device includes a first inflow passage and a second inflow passage. The first inflow passage, which is part of the circulation passage, is provided to allow the air having cooled the battery cells to be sucked into the fan device. The second inflow passage makes communication between the outside of the case and the fan device to allow air outside the case to be sucked into the circulation passage by suction force of the fan device.

  • Patent number: 10403942
    Abstract: A cooling system for cooling a main battery 10 includes a cooling fan 40 and a temperature sensor 61 configured to detect a battery temperature TB. The cooling system performs constant control in which the cooling fan 40 is driven at a constant command value when the battery temperature TB reaches or exceeds a first temperature T0 after startup of the electrically powered vehicle. Additionally, the cooling system detects whether or not a malfunction occurs in the cooling fan 40, based on an actual rpm of the cooling fan 40 obtained during the constant control. The cooling system performs the constant control in a situation in which charging of the main battery 10 is continued for a predetermined period of time or longer after the startup of the vehicle, regardless of whether the battery temperature TB is below the first temperature T0.
