Claim 13:
14. An air conditioning apparatus that emits cooled air into a cabinet cluster containing electronic equipment, the air conditioning apparatus including:
a heat exchange unit containing an exhaust fan;
an outside air inlet;
a filter chamber comprising an air intake area configured to provide filtered air; and
a cooling unit coupled to the filter chamber comprising:
a cooling unit fan operable to push the filtered air through the air cooling area and into the cabinet cluster, wherein one or more of said exhaust fan and said cooling unit fan is configured with a weighted rotor assembly for storing angular kinetic energy during rotation of the one or more of said exhaust fan and said cooling unit fan, wherein said weighted rotor assembly is associated with a means to generate electricity for continuous operation of variable frequency drive circuits of said exhaust fan and said cooling unit fan, the stored energy being sufficient to continue powering variable frequency drive circuits of said exhaust fan and said cooling unit fan, and to continue delivering at least a predetermined flow of cooled air from said cooling area into said cabinet cluster for an interim period between loss of grid power to said air conditioning apparatus and a back-up generator coming on-line.
