Abstract: A vapor compression system that includes a reheat coil that heats a supply air stream flowing across the reheat coil with a refrigerant. A fan forces an environmental air flow across a condenser to remove energy from the refrigerant. A controller adjusts a speed of the fan to control a flow of the refrigerant through the reheat coil.

Abstract: The present disclosure relates to a heating, ventilation, and/or air conditioning (HVAC) system that has a first circuit and a second circuit that each have a compressor and a condenser, a conduit extending from the second circuit downstream of the condenser to the first circuit upstream of the compressor, a valve along the conduit that may manage flow therethrough, and a controller that may operate the HVAC system in a first mode such that each circuit separately circulates the refrigerant in each circuit and transition to a second mode such that refrigerant-sharing occurs between the circuits. In response to a request to transition from the second mode to the first mode, the controller may determine an amount of refrigerant subcooling, compare the amount to a threshold value associated with the first mode, and instruct opening of the valve upon a determination that the amount is less than the threshold value.

Abstract: In one embodiment, a cooling system includes an evaporator, which further includes an evaporator tube, a first mechanical wave emitter, and a control system communicatively coupled to the first mechanical wave emitter. The cooling system is configured to circulate refrigerant through the evaporator tube to facilitate heat exchange between the refrigerant and fluid surrounding the evaporator tube. The first mechanical wave emitter is configured to output first mechanical waves to the evaporator tube, and the control system is configured to instruct the first mechanical wave emitter to output the first mechanical waves to enhance nucleation of the refrigerant in the evaporator tube.

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.
