An air-treatment system includes a cooling circuit, a first heat exchanger
in thermal communication with the cooling circuit, and a secondary
circuit in thermal communication with the first heat exchanger. The
air-treatment system also includes a controller in communication with at
least one of the cooling circuit, the first heat exchanger, and the
secondary circuit. The controller is operable to receive at least one
input indicative of a desired ambient condition, operable to receive at
least one input indicative of current ambient conditions, operable to
receive at least one input indicative of at least one of the cooling
circuit operation and secondary circuit operation, and operable to change
the operation of at least one of the cooling circuit and the secondary
circuit when the current ambient condition is outside of a desired
operation condition range.
