    Abstract: A HVAC assembly includes a temperature mixing valve that comprises a shaft, an upper paddle, a lower paddle, and a yielding means. The upper paddle and the lower paddle attach to the shaft. The yielding means applies a force to keep the upper paddle sealed to prevent cold air in a cold air inlet from entering a mixing zone and the lower paddle moves away from a shared sealing boundary over a predetermined angle of rotation before the upper paddle initially moves to allow cold air to enter the mixing zone. Movement of the lower paddle away from the shared sealing boundary allows cold air to enter a hot air inlet and admix with hot air to mix in the mixing zone to produce non-stratified air.

    Abstract: A series-parallel condensing system comprised of an air-cooled condenser, a surface condenser, a circulating water system and a cooling tower, body of water, or other equivalent heat sink. The cooling tower, being an evaporative device, consumes water. In the simplest embodiment of the invention steam is condensed in a two-stage series process with steam first fed to an air-cooled condenser where the majority of the steam is condensed and then to a surface condenser, which in conjunction with the circulating water system and cooling tower condenses the remaining steam. This embodiment achieves the greatest degree of water conservation. The function of the surface condenser is to replace the dephlegmator of the air-cooled condenser, which results in a significant reduction in the size and cost of the air-cooled condenser and also yields improved plant performance and operational simplicity.

    Abstract: An apparatus for cooling N heat-producing devices, where AT is an integer no smaller than one, using a cooling fluid that may be supplied at a temperature below the dew-point temperature of ambient air. To avoid condensation on the heat-producing devices, the cold fluid is warmed, upstream of the heat-producing devices, to a temperature T0 that is above the dew-point. The warming is accomplished, in a heat exchanger, by the warm fluid returning from the heat-producing devices. The amount of warming is controlled by periodically measuring T0 as well as the N temperatures downstream of the N heat-producing devices, and sending these N+1 temperature measurements to a control element that implements a control algorithm whose purpose is to achieve a set-point value of T0 by regulating, via N control valves, the flow of fluid to the N heat-producing devices. Also provided is a method for cooling the N heat-pro during devices pursuant to the inventive apparatus by a temperature control over the cooling fluid.

  • Patent number: 7836945
    Abstract: An exhaust gas heat exchanger system of a combustion engine has a bypass duct and a heat exchanger duct with a heat exchanger. A valve is controlled by determining when heat is to be transferred from exhaust gas flowing through the exhaust system to the heat exchanger. When heat is to be transferred, the valve is switched into a first position in which all of the exhaust gas flows through the heat exchanger duct. A pressure drop across the heat exchanger system is monitored either directly or indirectly. If the pressure drop reaches a predefined limit, the valve is switched into an intermediate position, resulting in a smaller portion of the exhaust gas flowing through the heat exchanger duct than when the valve is in the first position and a remaining portion flowing through the bypass duct, thereby reducing the pressure drop across the heat exchanger system.

When a temperature of the oil is relatively low, the thermo valve supplies oil passed through the first heat exchanger to the automatic transmission and shuts off a flow of oil from the second heat exchanger to the automatic transmission. When a temperature of the oil is relatively high, the thermo valve supplies oil passed through first and second heat exchangers to the automatic transmission.

  • Patent number: 7610949
    Abstract: A heat exchanger with an external bypass is formed by a core portion including a plurality of stacked tubular members and a corrugated bypass tube positioned substantially parallel to the core portion. A first set of flow passages is defined within the tubular members for the flow of a first fluid therethrough, and a second set of flow passages is defined between adjacent tubular members as the tubular members are stacked together to form the core portion. A pair of external end plates is sealingly attached to transverse end wall portions of the stacked tubular members and to the ends of the bypass tube thereby forming the heat exchanger with an external bypass that comprises a single unit that can be brazed or joined together in a single operation.

  • Patent number: 7604045
    Abstract: Provided is an air conditioner for a vehicle, including a blower unit that blows air, an air conditioning case including an evaporator and a heater core, which are sequentially disposed in an airflow path, and an air inlet path that allows air to flow to an evaporator from the blower unit, wherein the airflow path includes a first path that allows air entered from the air inlet path to flow to a lower part of the evaporator and second and third paths that allow the air to flow to the lower part of the evaporator after passing through both sides of the evaporator. The air conditioner increases an amount of airflow and reduces airflow resistance since airflow paths are formed on both sides of the evaporator in addition to a direction perpendicular to the separator. Consequently, the airflow entering a lower part of the evaporator can be uniformly distributed.

  • Patent number: 7604042
    Abstract: A processing apparatus is provided with a showerhead for introducing a process gas into a processing vessel, and heaters for heating the showerhead to an elevated temperature. The processing apparatus is provided with a main flow line for a cooling liquid, and a bypass flow line connected to the main flow line so as to bypass the showerhead. A cooling liquid control system for controlling the flow of the cooling liquid includes shutoff valves, and a valve controller. The cooling liquid control system controls the flow of the cooling liquid such that the cooling liquid is prevented from flowing through the cooling passage while the showerhead is being heated to the elevated temperature, and such that the cooling liquid is made to flow through both the cooling passage and the bypass flow line while the showerhead is being cooled to a reduced temperature.
