  • Managing high pressure events in air conditioners
    Patent number: 10408516
    Abstract: In various implementations, an air conditioner may include one or more compressors, more than one expansion device, and/or a microchannel condenser. High pressure events may occur during operation of the air conditioner and may be identified. When a high pressure event is identified a bypass operation may be allowed.
    Type: Grant

  • Variable Speed Outdoor Fan Control
    Publication number: 20150338111
    Abstract: A method and apparatus for setting the speed of a fan during operation of an HVAC system are provided. The HVAC system may comprise a heat exchanger, a fan, and a sensor disposed within an outdoor unit of the HVAC system. A controller coupled to the fan and sensor may receive a first signal from the sensor indicating one or more ambient air temperature values and determine a desired speed setting of the fan using at least the one or more ambient air temperatures indicated by the first signal. The controller may further generate a control signal based on the desired speed setting and transmit the control signal to the first fan.

  • FAN OPERATION MANAGEMENT
    Publication number: 20150276299
    Abstract: In various implementations, an air conditioner may manage operations of fan(s) of the air conditioner. The air conditioner may determine properties of the air conditioner (e.g., ambient temperature and/or pressure of a portion of the air conditioner) and determine setting(s) for fan(s) and/or a crankcase heater based on the determined properties.
