Integrated hvac system with variable refrigerant flow unit and air handling unit

A rooftop unit of a heating, ventilation, and air conditioning (HVAC) system, comprising:

• a housing defining a variable refrigerant flow (VRF) section and an air handling unit (AHU) section, wherein the housing comprises a partition extending therethrough and separating the VRF section and the AHU section;
• a vapor compression system, comprising:
• a VRF unit comprising a variable speed compressor, a first heat exchanger, and a reversing valve disposed within the VRF section;
• and
• an AHU comprising a second heat exchanger disposed within the AHU section,
• wherein the VRF unit and the AHU are pre-packaged within the housing, the reversing valve is configured to adjust a flow direction of a refrigerant through a refrigerant circuit of the vapor compression system to adjust operation of the vapor compression system between a heating mode and a cooling mode, the second heat exchanger is configured to place the refrigerant in a heat exchange relationship with an air flow, and the AHU section is configured to discharge the air flow into a conditioned space.

A packaged unit of a heating, ventilation, and air conditioning (HVAC) system, comprising:

• a housing defining a variable refrigerant flow (VRF) section and an air handling unit (AHU) section, wherein the housing comprises a partition separating the VRF section and the AHU section;
• a vapor compression system, comprising:
• a refrigerant circuit configured to operate in a cooling mode to cool an air flow and to operate in a heating mode to heat the air flow;
• a plurality of VRF units disposed within the VRF section, wherein each VRF unit of the plurality of VRF units comprises a compressor, a first heat exchanger, and a reversing valve;
• and
• an AHU disposed within the AHU section, wherein the AHU comprises a second heat exchanger configured to place a refrigerant of the refrigerant circuit in a heat exchange relationship with the air flow, and the AHU is configured to discharge the air flow directly into a conditioned space.
