  • Facilitating cooling of an electronics rack employing water vapor compression system
    Patent number: 8120916
    Abstract: A cooling apparatus and method are provided for facilitating cooling of an electronic apparatus that includes a semiconductor element. The cooling apparatus includes an evaporator containing a coolant and evaporating the coolant under a reduced pressure lower than an ambient pressure to generate a chilled coolant, a condenser regenerating the coolant from a vapor of the coolant and being fluid-communicated with the evaporator through a bypass line, and a circulating pump and a line supplying the chilled coolant to a heat exchange area of the electronic apparatus to conduct a heat exchange with an air flow passing though the semiconductor element at a hot side of the electronic apparatus and returning the coolant after the heat exchange to the condenser.
    Type: Grant

  • Ventilating window
    Patent number: 5864989
    Abstract: A ventilating window for ventilating the interior of a building or a structure such as a vehicle in a natural and gentle manner. A ventilating window for the exhaust of air is provided with a mechanism for automatically opening a window casement when the atmospheric pressure inside the window is higher than the outside atmospheric pressure, thereby dispensing with forced exhaust using a fan or the like. A ventilating window for the supply of air is provided with a mechanism for automatically closing a window casement when the atmospheric pressure outside the window is higher than the inside atmospheric pressure, thereby preventing a strong wind from blowing into the interior. A ventilating window for both exhaust and supply of air is provided with both such opening mechanism and closing mechanism.
