Air handling unit with a canopy thereover for use with a data center and method of using the same

An air conditioning system for a building requiring a high volume of cooled air, the building having an exterior wall that provides a barrier against the external environment and includes a heated air opening disposed adjacent to a return air opening, the system comprising:

• a warm exhaust outlet duct formed through the heated air opening;
• a cool air inlet duct formed through the return air opening;
• an air conditioning apparatus connected to and that receives heated air from the warm exhaust outlet duct, connected to and emits cooled air into the cool air inlet duct, and configured to emit vented air into the external environment through an exhaust opening, the air conditioning apparatus disposed in the external environment, external to the exterior wall, and mounted adjacent the exterior wall, the air conditioning apparatus further including:
• a heat exchanged unit containing at least one exhaust fan that emits heat from the heated air as the vented air, thereby allowing return air to pass through a return opening that contains a return damper disposed therein;
• an exhaust canopy that covers the at least one exhaust fan and provides an opening through which the vented air will pass to the external environment, the exhaust canopy further including a plurality of louvers, the plurality of louvers being controlled to open or close;
• a filter chamber, the filter chamber including an air intake area coupled to the heat exchange unit and an air filter, the filter chamber being configurable to receive the return air based upon a return air damper position, the filter chamber providing filtered air;
• a cooling unit coupled to the filter chamber that has an air cooling area through which the filtered air passes to create the cooled air, the cooling unit including:
• a direct cooling coil filled with a cooling substance which the filtered air passes, the cooling substance being circulated through a condenser unit disposed within a walled area of the air conditioning apparatus, the heat exchange unit being disposed above the filter chamber and the condenser unit, the condenser unit top surface being adjacent to the top surface of the heat exchange unit;
• at least one condenser fan associated with the condenser unit to emit heat from the cooling substance being circulated, the heat being vented into the external environment, thereby allowing the cooling substance to cool and condense;
• a condenser canopy that covers the at least one condenser fan and provides an opening through which the heat will pass to the external environment, the condenser canopy further including a plurality of condenser louvers, controllable to open or close;
• and
• one or more air cooling area fans operable to push the filtered air through the air cooling area and toward the cool air inlet duct.
