Claim 9:
10. A heating, ventilating, and air conditioning (HVAC) system, comprising:
a housing;
a refrigerant loop disposed within the housing, wherein the refrigerant loop comprises:
a compressor configured to circulate a refrigerant through the refrigerant loop;
a first heat exchanger disposed in a portion of the housing exposed to an ambient environment surrounding the housing, wherein the first heat exchanger is configured to place the refrigerant in a first heat exchange relationship with ambient air received from the ambient environment; and
a second heat exchanger configured to place the refrigerant in a second heat exchange relationship with a working fluid;

an air handling unit disposed within the housing, wherein the air handling unit comprises:
a third heat exchanger disposed within an airflow path of the air handling unit, wherein the third heat exchanger is configured to place the working fluid in a third heat exchange relationship with an airflow directed along the airflow path,
wherein the air handling unit is configured to receive a flow of outside air into the housing and to discharge the airflow from the housing and into a building; and

a barrier disposed within the housing between the refrigerant loop and the air handling unit, wherein the barrier is configured to isolate the refrigerant loop from the air handling unit.
