  • Patent number: 10047970
    Abstract: An HVAC controller may be controlled in response to a natural language audio message that is not recognizable by the HVAC controller as a command, where the natural language audio message is translated into a command recognizable by the HVAC controller. The HVAC controller may be a thermostat and may include a housing that at least partially houses a control module, a microphone, a speaker, a display, and a voice recognition module. The voice recognition module recognizes a predetermined audible trigger from a recorded voice message or streamed voice message, and in response, provide one or more audio clips via the speaker and/or video clips via the display to assist users in operating the thermostat. A user may communicate with the thermostat via the thermostat and/or a remote device.

  • Patent number: 10036578
    Abstract: A method is disclosed for uniformly cooling a cooling plate of a heat generating device. Sub-cooled refrigerant is flowed through a thermal expansion valve and then into the cooling plate as a two-phase refrigerant where the refrigerant is superheated. Any refrigerant remaining in a fluid state before reaching a sensing portion associated with the thermal expansion valve and exiting the cooling plate can be completely vaporized by a recuperative heat exchanger. The superheated refrigerant is then passed to the sensing portion so that the superheated refrigerant directly transfers heat to a fluid within the sensing portion and causes a pressure change that is communicated to a needle of the thermal expansion valve.

  • Patent number: 10011361
    Abstract: An Environmental Control System (ECS) which includes a heat exchanger (HX) and an air conditioning unit (ACU) upstream of the heat exchanger. The heat exchanger receives flows of hot air bled from a plurality of aircraft engines and flows of cold ambient air drawn from the aircraft exterior for use by the heat exchanger and the air conditioning unit for heating and cooling the interior cabin of the aircraft. The environmental control system may operate in one of several modes, whether the heat exchanger and air conditioning unit are operating normally or have failed. In a normal mode, the air conditioning unit and heat exchanger operate in series. In an “ACU only” mode, the air conditioning unit operates without the heat exchanger. In an “HX only” mode, the heat exchanger operates without the air conditioning unit. In an “ECS off” mode, both the heat exchanger and air conditioning unit are bypassed.
