Abstract: A heating, ventilation, and/or air conditioning (HVAC) system has a refrigerant circuit that includes a compressor, a condenser system with a first set of tubes and a second set of tubes fluidly separate from the first set of tubes within the condenser system, and a valve positioned downstream of the compressor and upstream of the second set of tubes relative to a direction of refrigerant flow through the refrigerant circuit, in which the refrigerant circuit is configured to direct refrigerant through the first set of tubes and through the second set of tubes. The HVAC system further has a switch configured to detect an operating parameter and to instruct the valve to close based on the operating parameter such that refrigerant flow is blocked through the second set of tubes and refrigerant flow is enabled through the first set of tubes.

Abstract: A heating, ventilation, and/or air conditioning (HVAC) unit includes a cabinet defining a cabinet interior configured to house components of the HVAC unit. The cabinet includes an opening defining an air flow path between the cabinet interior and an external environment. The HVAC unit also includes a fan assembly including fan blades configured to move an air flow through the opening, wherein the fan assembly is configured to enable translation of the fan blades through the opening between a shipping arrangement in which the fan blades are disposed in the cabinet interior and an operational arrangement in which the fan blades are disposed in the external environment.
