  • Patent number: 11188104
    Abstract: An electronic thermostat replaces an electro-mechanical thermostat and is located in a different location from the blower motor it controls. The electronic thermostat controls the blower motor on the same wires from which the thermostat receives power. The safe, low voltage power supply that powers the electronic thermostat is located at the blower motor location and is housed in the Blower Motor Module (BMM). This configuration has the advantage that it removes a bulky and space consuming component from the thermostat, the A/C transformer. This also reduces the amount of power (heat) dissipated by the electronic thermostat power supply, thus reducing a source of potential temperature measurement inaccuracies. Also, removing the 120 VAC power from the thermostat and replacing it with an isolated low voltage source increases safety.

A precision air device having a standalone controllable fan with directional nozzles is provided. The precision air device includes environmental and occupancy sensors, and communicates with a user device and with other precision air devices in the space. Application software installed on an occupant's user device enables the occupant to specify whether it is too cold or too warm within his or her personal space, or microzone. The collective demand of all microzones within a VAV macrozone is determined by a precision air aggregator to adjust a controllable VAV damper for that macrozone.

  • Patent number: 11187425
    Abstract: A method for providing a variable fan-off delay after a thermostat call for cooling or after a heating on cycle for a Heating, Ventilation, Air Conditioning (HVAC) system. The variable fan-off delay may be ended based on comparing a measurement of a Conditioned Space Temperature (CST) to a CST threshold. The CST threshold may be based on a previous measurement of the CST monitored during the current variable fan-off delay. The CST threshold may be an inflection point where the rate of change of the CST with respect to time equals zero plus or minus a confidence interval tolerance. The CST threshold may also be a fan-off delay differential offset or a thermostat setpoint differential where the variable fan-off delay is ended when the measurement of the CST during the variable fan-off delay crosses the differential at least once after the cooling or heating on cycle.

  • Patent number: 11117448
    Abstract: An air-conditioning control apparatus includes a determiner and a controller. The determiner is configured to determine whether a subject vehicle is in a slipstream of a preceding vehicle when the subject vehicle is in autonomous control and following the preceding vehicle. The controller is configured to increase a flow rate of air flowing through a condenser for an air-conditioning of the subject vehicle when the determiner determines that the subject vehicle is in the slipstream of the preceding vehicle. According to this, even when the subject vehicle is in the slipstream and following the preceding vehicle during the autonomous control, the flow rate of the air flowing through the condenser can be increased by the controller. Accordingly, the flow rate of the air flowing through the condenser of the subject vehicle can be secured in the condition where the inter-vehicle distance from the preceding vehicle is small during vehicle platooning.
