摘要： 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.

摘要： 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.

摘要： 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.

摘要： An air economizer of a heating, ventilation, and air conditioning (HVAC) system includes an outdoor air compartment configured to receive outdoor air, and an indoor air compartment configured to receive indoor air. The air economizer also includes a partition extending between the outdoor air compartment and the indoor air compartment. The partition is configured to move between a first position and a second position such that a damper of the air economizer receives the indoor air when the partition is in the first position, and such that the damper receives the outdoor air when the partition is in the second position.
