INTEGRATED HVAC SYSTEM WITH VARIABLE REFRIGERANT FLOW UNIT AND AIR HANDLING UNIT

摘要

A heating, ventilation, and air conditioning (HVAC) system (100) includes a variable refrigerant flow (VRF) unit (200) including a variable speed compressor (222), a VRF heat exchanger (216), and a reversing valve (220) of a vapor compression circuit (214). In addition, the HVAC system (100) includes an air handling unit (AHU) (202) including an AHU heat exchanger (224) of the vapor compression circuit (214). Furthermore, the HVAC system (100) includes a housing (204), wherein the VRF unit (200) and the AHU (202) are disposed within the housing (204), and wherein the variable speed compressor (222) is configured to circulate a refrigerant through the VRF heat exchanger (216) and the AHU heat exchanger (224), and the reversing valve (220) is configured to adjust a flow direction of the refrigerant through the vapor compression circuit (214) to adjust operation of the HVAC system (100) between a cooling operation mode and a heating operation mode.
