Abstract: Systems and methods to control an electronic expansion valve (EEV) of a vapor compression system are described. A heating ventilation, and air conditioning (HVAC) system includes control circuitry having a sensor. The control circuitry sets a control setpoint of a vapor compression system such that an electronic expansion valve operates across a first operating range. The control circuitry receives a signal from the sensor indicative of an operating condition of the vapor compression system. The control circuitry adjusts the control setpoint based at least in part on the operating condition. The control circuitry controls operation of the electronic expansion valve based at least in part on the adjusted control setpoint, wherein the electronic expansion valve operates across a second operating range, different from the first operating range, at the adjusted control setpoint.

Abstract: A controller for a heating, ventilation, and air conditioning (HVAC) system is configured to receive a first feedback from a first sensor of the HVAC system and receive a second feedback from a second sensor of the HVAC system. The controller is configured to determine a saturated parameter corresponding to a working fluid based on the second feedback. Additionally, the controller is configured to transmit an indication in response to determining that the saturated parameter has a threshold correlation to the first feedback.

Abstract: The present disclosure relates to a zoning system for climate control including a controller configured to operate the zoning system to supply conditioned air to a first zone of a plurality of zones through a first supply air damper to thermally charge the first zone. The controller is also configured to close the first supply air damper of the first zone and open a second supply air damper of a second zone of the plurality of zones after the first zone is thermally charged. The controller is further configured to operate the zoning system to draw the conditioned air from the first zone and supply the conditioned air to the second zone through the second supply air damper.

Abstract: A climate management system includes a conditioning unit having a reversible fan and an enclosure. The enclosure separates an inner space of the enclosure from an external environment while allowing air flow therethrough. The reversible fan is configured to be turned by a fan motor in a first circumferential direction to pull air from the external environment into the inner space of the enclosure. The climate management system includes a monitoring system configured to monitor operational characteristics of the climate management system, and to communicate data feedback corresponding to the operational characteristics. The climate management system includes a controller configured to instruct, based on analysis of the data feedback, the fan motor to turn in a second circumferential direction opposite to the first circumferential direction to push air from the inner space into the external environment.

Abstract: The present disclosure presents techniques for improving operational efficiency of climate control systems. A climate control system may include climate control equipment, a sensor that measures temperature in a building, and a control system that controls operation of the equipment using a first temperature schedule, which associates each time step with a temperature setpoint, when the building is occupied. When not occupied, the control system determines an expected return time based on historical occupancy data associated with the building, determines the temperature setpoint associated with the expected return time, determines candidate schedules each expected to result in the inside air temperature meeting the temperature setpoint, determines efficiency metrics each associated with one of the candidates based on historical performance data resulting from previous operation of the climate control system, and controls operation of the equipment based on a second temperature schedule selected from the candidates based on associated efficiency metrics.

Abstract: The present disclosure includes a heating, ventilation, and air conditioning (HVAC) system having a control system suitable to control operation of a device in the HVAC system. The control system may include a zone control panel that may control operation of the device using power-line communication. Accordingly, the zone control panel and the device may be both communicatively and electrically coupled via one or more power lines. To that end, the zone control panel may determine a primary address identifying the device and/or a secondary address indicating the one or more power lines electrically coupled to the device. Further, the zone control panel may communicate with and/or coordinate operation of the device by transmitting data messages to the device via the one or more power lines based on the primary address and/or the secondary address.
