Abstract: A heating, ventilation, and air conditioning system includes a plurality of sensors including a first sensor configured to measure an outside air temperature of outside air, a second sensor configured to measure a return air temperature of return air, and a third sensor configured to measure a mixed air temperature of mixed air. The system also includes a controller communicatively coupled to the plurality of sensors. The controller is configured to determine that data from one of the plurality of sensors is unavailable and estimate the data from the one of the plurality of sensors based on data from other sensors of the plurality of sensors.

Abstract: A heating, ventilation, and air conditioning (HVAC) system includes a compressor having a discharge port and a suction port, a first sensor configured to provide feedback corresponding to a first temperature of the working fluid exiting the compressor proximate the discharge port, a second sensor configured to provide feedback corresponding to a second temperature of the working fluid entering the compressor proximate the suction port, and an automation controller storing data indicative of an operational envelope. The operational envelope defines compressor operation coordinates corresponding to a range of suction temperatures and a range of discharge temperatures inside and outside of a target region of the operational envelope, and the automation controller is configured to control a target range of compressor speeds based on a comparison of the target region to an operation coordinate defined by the feedback from the first sensor and the feedback from the second sensor.

Abstract: A heating and cooling system that includes a condenser coil configured to receive a refrigerant. A first compressor and a second compressor that pump the refrigerant through the condenser coil. A first condenser fan and a second condenser fan that push air over the condenser coil. A controller that receives a signal indicative of an ambient air temperature, a signal indicative of an operational status of the first compressor, and a signal indicative of an operational status of the second compressor. The controller controls operation of the first condenser fan and the second condenser fan in response to the signal indicative of the ambient air temperature, the signal indicative of the operational status of the first compressor and the signal indicative of the operational status of the second compressor.

Abstract: A controller for an economizer that provides outdoor air to a conditioned space. The controller includes an error calculator configured determine an indoor air quality (IAQ) setpoint error based on an actual IAQ and an IAQ setpoint, an outdoor air flow (OAF) setpoint adjuster configured to determine an adjusted OAF setpoint based on at least one of the IAQ setpoint error, an initial OAF setpoint, and an OAF setpoint upper limit, and a proportional variable deadband controller (PVDC) configured to adjust an operational deadband of the economizer and adjust an operation of at least one of an actuator and a damper of the economizer to achieve the adjusted OAF based on at least one of an actual OAF and the adjusted OAF setpoint. Achieving the adjusted OAF drives the actual IAQ to the IAQ setpoint.
