Abstract: The present disclosure relates to a heating, ventilation, and/or air conditioning (HVAC) system including an enclosure that is divided by a partition extending between a first panel and a second panel of the enclosure such that the partition defines an outdoor air flow path and a return air flow path through the enclosure. The partition includes an opening extending between the outdoor airflow path and the return airflow path. The HVAC system also includes an energy recovery wheel that translatably extends through the opening and is positioned within the outdoor air flow path and the return air flow path. The energy recovery wheel is disposed within the enclosure at an oblique angle relative to the outdoor air flow path and the return air flow path.

Abstract: A heating, ventilation, and/or air conditioning (HVAC) system includes an air flow path through which an air flow is routed. The HVAC system also includes a first condenser coil positioned in the air flow path and configured to receive a first portion of a refrigerant from a refrigerant conduit. The HVAC system also includes a second condenser coil positioned in the air flow path downstream from the first condenser coil relative to the air flow, and configured to receive a second portion of the refrigerant from the refrigerant conduit in parallel with the first portion of the refrigerant received by the first condenser coil.

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.
