    Abstract: Room heat exchangers of varying priority are provided by setting the volumetric flow rate of a medium by means of the room heat exchangers of a heating or cooling system. A target spread of the flow and return temperatures for each individual room heat exchanger(s) is set by fixably or adjustably limiting the respective room heat exchanger valve(s). A system-specific target spread for high-priority room heat exchangers is a basis to allow a lower target spread and a higher target spread is ensured given low-priority room heat exchangers. When operating in a high-priority room heat exchanger with a lower spread, the volumetric flow through at least one low-priority room heat exchanger with a higher spread is changed in such a way that a return temperature optimized for the heating device of the heating system is set by mixing the return medium from all room heat exchangers of the heating system.

  • Publication number: 20120199660
    Abstract: An electronic thermostat and associated methods are disclosed for power stealing from an HVAC triggering circuit. The methods include making voltage measurements while controlling the amount of current drawn by the power stealing circuitry so as to determine a relationship that can be used to select how much current to draw during power stealing. Through the use of the described methods, the likelihood of inadvertent switching of the HVAC function (on or off) can be significantly reduced.

  • Patent number: 8230910
    Abstract: An apparatus for conveying a cooling air flow for at least one motor vehicle heat exchanger has a fan frame, a fan wheel, a fan control unit, and a cooling body. The fan frame has a frame opening, which the fan wheel rotates within. The fan control unit is arranged in an edge region of the frame opening. The cooling body cools the fan control unit and has cooling domes. A first cooling dome is arranged entirely radially exterior to the frame opening and a second cooling dome is located partially radially within the frame opening and partially radially exterior to the frame opening. The first cooling dome exchanges heat with an auxiliary flow that flows radially exterior to the frame opening with respect to the center of the fan wheel when the fan wheel rotates.

    Abstract: A coolant flow control system includes an integrated pump for delivering an engine coolant to an engine, coolant flow control and heat exchange device. According to the system, coolant flow from the engine is delivered back to the engine after passing through the valve body part and then the heat exchange part in which it passes over the heat exchange part. Systems of the invention are particularly useful with all-electric and hybrid vehicles.

    Abstract: An air-conditioning apparatus includes a heat medium side device with plural pumps for circulating the heat medium related to the heating or the cooling of plural intermediate heat exchangers. Plural use side heat exchangers exchange heat between the heat medium and air. Plural flow path switching valves switch the flow path for supplying the heat medium related to a selected system among the heating media circulating in plural systems to each use side heat exchanger. A relay unit side control device controls the flow path switching valves so as to circulate the heat medium between the use side heat exchanger causing the heat medium to absorb the heat and the use side heat exchanger causing the heat medium to emit the preferentially set heat, when it is determined that it is impossible to perform the heating or the cooling of the heat medium by the intermediate heat exchanger.

    Abstract: A cooling system for an electric vehicle includes: a cooling unit that cools an electric drive unit; and a control unit that controls cooling of the electric drive unit by controlling the cooling unit. The control unit controls the cooling unit in a first cooling mode that provides a first cooling capacity when a force for driving the electric vehicle due to the electric drive unit is in a first operational region, and controls the cooling unit in a second cooling mode that provides a second cooling capacity that is higher than the first cooling capacity when the force due to the electric drive unit is in a second operational region that is higher than the first operational region; and in the second cooling mode, the control unit controls the cooling unit so that the second cooling capacity becomes higher as a rotational speed of the electric drive unit decreases.

  • Patent number: 8190303
    Abstract: In a particular embodiment, a system to dissipate heat in an information handling system includes a first heat-generating component adapted to process first data and a second heat-generating component adapted to process second data. The system also includes a cooling fluid guide including an electroactive material. The cooling fluid guide is adapted to change from a first shape to a second shape, in response to receiving a trigger voltage or in response to no longer receiving the trigger voltage. The system also includes a controller adapted to detect a data load processed at the second heat-generating component and, in response to detecting the data load, to cause the trigger voltage to be received at, or no longer received at, the cooling fluid guide. The cooling fluid guide is adapted to direct an increased portion of cooling fluid toward the first heat-generating component when the cooling fluid guide is in a form of the second shape, as compared to the first shape.

  • Publication number: 20120097360
    Abstract: An air conditioner sucks air exhausted from an information processor, and cools down the sucked air. The air conditioner exhausts the cooled air. The air conditioner acquires a cooling state, determines whether a cooling capacity exceeds an upper limit value, and reduces the volume of exhaust air when it is determined that the cooling capacity exceeds the upper limit value. For example, the air conditioner calculates a thermal load as the cooling state by using the volume of exhaust air, a difference between the temperature of exhaust air and the temperature of suction air, and determines that the cooling capacity exceeds the upper limit value when the calculated thermal load exceeds a given threshold. The air conditioner measures the temperature of exhaust air, and determines that the cooling capacity exceeds the upper limit value when the measured temperature exceeds a set value.

    Abstract: A personal cooling system, such as for a cabless or other open-cab vehicle, includes a contact cooler that contacts the vehicle user, a forced-air cooler that directs cooled air to the vehicle user, and a recirculating fluid system that is operatively coupled to both the contact cooler and the forced-air cooler to provide cooling to both the contact cooler and the forced-air cooler. Contact cooling may be provided to the upper back of a vehicle user. Forced-air cooling may be provided on any of a number of areas of the user's body. The system may be able to detect the presence of a user in the seat. The detection of a user may trigger an initial relatively high level of cooling, which is followed after a predetermined time by a reduction of the level of cooling to a relatively low level of cooling.

    Abstract: Methods and systems for controlling temperatures in plasma processing chamber for a wide range of setpoint temperatures and reduced energy consumption. Temperature control is coordinated between a coolant liquid loop and a heat source by a control algorithm implemented by the plasma processing module controller. The control algorithm may completely stop the flow of coolant liquid to a temperature-controlled component in response to a feedback signal indicating an actual temperature is below the setpoint temperature. The control algorithm may further be based at least in part on a feedforward control signal derived from a plasma power or change in plasma power input into the processing chamber during process recipe execution.
