  • Patent number: 10088178
    Abstract: A method for air conditioning including installing an air conditioning unit at a desired location. The air conditioning unit includes a housing that has air supply inlets and exhaust air outlets. The housing encloses a mode control unit that switches a zone coil associated with a zone from a cooling mode to a heating mode by switching from a cooling medium to a heating medium flowing through the zone coil. The zone coil receives the heating or cooling medium and conditions incoming air from a supply fan to be exhausted in a zone associated with the zone coil. A variable refrigerant flow cooling/heating unit provides a cooling medium or a heating medium at varying rates to control a temperature of a zone.

  • Patent number: 10082068
    Abstract: A radiator for cooling a heated coolant includes an air guide for preventing heat damage. The air guide is adapted to allow air entering into the radiator due to the operation of a cooling fan to flow into a gear box of a fan clutch, wherein the cooling fan is installed at an inside of the vehicle and is activated by the fan clutch. The air guide can be installed above the cooling fan and thus allow air entering due to the operation of the cooling fan to flow horizontally, and further allow the air to flow vertically and downwardly such that the air is ejected downwardly towards a region where the gear box is installed.

  • Patent number: 10054327
    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 including a housing that houses a temperature sensor, a microphone, and a controller. The controller may identify a trigger phrase in an audio stream provided by the microphone. In response to identifying the trigger phrase, the controller initiates processing of the audio stream to identify a command following the trigger phrase and to generate a command understandable by the thermostat that instructs the controller to perform the identified command. The controller then executes the generated command understandable by the thermostat. A user may communicate with the thermostat via the microphone of the thermostat and/or a remote device having a microphone.

  • Patent number: 10052937
    Abstract: There is provided a vehicle air conditioning apparatus that can prevent the amount of the refrigerant discharged from the compressor from reducing when an outside air temperature is low to achieve a heating performance required for a heating operation, and also can dehumidify the vehicle interior without deteriorating the heating performance during a heating and dehumidifying operation. The vehicle air conditioning apparatus includes: a heat released refrigerant expansion valve that decompresses the refrigerant discharged from the radiator during the heating operation and the first heating and dehumidifying operation; a gas-liquid separator that separates the refrigerant decompressed by the heat released refrigerant expansion valve into a gaseous refrigerant and a liquid refrigerant; and a bypass circuit that allows part of at least the gaseous refrigerant separated in the gas-liquid separator to flow into a section of the compressor through which the refrigerant being decompressed passes.
