Abstract: A control system for a heating, ventilation, and air conditioning (HVAC) system includes a service database including information associated with an HVAC unit. The service database includes data comprising a physical location of the HVAC unit and a service history for the HVAC unit. The control system also includes a user device communicatively coupled to the service database. The user device includes a controller having a memory and a processor. Additionally, the controller is configured to receive user input via the user device indicative of a service action performed on the HVAC unit, and update the service database such that the service history includes the service action.

Abstract: A heating, ventilating, and air conditioning (HVAC) system includes a refrigerant loop having a compressor, where the compressor is configured to circulate a refrigerant through the refrigerant loop, a first heat exchanger disposed along the refrigerant loop, where the first heat exchanger is configured to place the refrigerant in a first heat exchange relationship with a working fluid, and an air handling unit having a second heat exchanger, where the second heat exchanger is configured to place the working fluid in a second heat exchange relationship with an airflow, and where the air handling unit is isolated from the first heat exchanger to reduce or eliminate mixing of refrigerant with the airflow.

Abstract: A fan assembly is provided. The fan assembly includes a fan, a motor that is coupled to the fan, and a variable frequency drive (VFD) that is coupled to the motor. The motor includes a maximum rated speed that is greater than a maximum structural speed limit of the fan, and the VFD includes a current output limit configured to limit an operational speed of the motor to be less than or equal to the maximum structural speed limit of the fan.

Abstract: A heating, ventilation, and air conditioning (HVAC) system includes an enclosure and an evaporator coil disposed within the enclosure. The HVAC system also includes a pivot member coupled between an edge portion of the evaporator coil and the enclosure. The pivot member is configured to enable the evaporator coil to pivot relative to the enclosure to adjust an operating angle of the evaporator coil during operation of the HVAC system. Additionally, the HVAC system includes an actuator configured to enable pivoting of the evaporator coil to a target operating angle based on an operating parameter input.
