  • Patent number: 11015845
    Abstract: Systems and methods for controlling temperature in an enclosed space can include an air-to-air heat exchanger (AAHX) and a direct evaporative cooler (DEC). The DEC can be located in a scavenger or outdoor air stream such that the DEC cools the outdoor air, which is then used to cool or reject heat from a process air stream passing through the AAHX. In an example, the AAHX can be a sensible wheel. In another example, the AAHX can be a counter-flow flat plate. The system can operate in various modes, including an economizer mode and an evaporation mode, depending, in part, on the outdoor air conditions and a load on the system. In some examples, the system can include a DX coil to provide additional cooling to the process air in another operating mode.

  • Patent number: 10823445
    Abstract: A refrigeration cycle apparatus according to the present invention, a controller is configured to cause a first operation mode and a second operation mode to be executed as operation modes of an air-sending fan. The first operation mode is an operation mode in which an operation of the air-sending fan is started based on a first manipulation performed on an operation unit and the air-sending fan is stopped based on a second manipulation performed on the operation unit. The second operation mode is an operation mode in which the operation of the air-sending fan is started when refrigerant is detected by a refrigerant detection unit, the air-sending fan is not stopped based on the second manipulation, the air-sending fan is stopped based on a third manipulation different from the second manipulation, and the operation of the air-sending fan is restarted based on a fourth manipulation different from the first manipulation.

    Abstract: An air-quality network system for homes, the air-quality network system having an air inlet unit, an air outlet unit, and a monitoring unit. The monitoring unit monitors, measures, and transmits information regarding the air quality to a network. The data management algorithm in the network compares the air quality information against preset/user-defined values and accordingly, determines the operating parameters of the air inlet and/or air outlet units. The system provides real-time monitoring and visualization of the air quality in the home, and provides emergency alerts if air quality exceeds safety limits.

  • Patent number: 10487791
    Abstract: An electric starter system is usable with a powertrain having an engine with a flywheel. The starter system includes a brushless starter motor having a machine temperature, and a solenoid operable for translating a pinion gear into meshed engagement with the flywheel and the starter motor in response to a requested engine start event. A controller has temperature regulation logic that includes a proportional-integral torque control loop. Execution of a method embodied by the logic, in response to the requested engine start event when the machine temperature exceeds a first temperature, causes the controller to determine a required starting torque of the starter motor using the control loop. The controller causes the starter motor to transmit the required starting torque to the engine at a level that reduces the machine temperature below the first temperature.
