1. An air-conditioning system, comprising:
a first air-processing apparatus having a first inlet, formed in a first surface thereof that extends perpendicular to a floor or a ceiling, and a first outlet, formed in a second surface thereof that extends perpendicular to the first inlet, the first air-processing apparatus being configured to induce air introduced into the first inlet to exchange heat with refrigerant and to be discharged through the first outlet;
a second air-processing apparatus having a second outlet, formed therein so as to be open in a same direction as the first outlet, and a second inlet, formed therein so as to be open in a same direction as the first inlet, wherein the air-conditioning system is operatable in a combined operation mode in which the first air-processing apparatus and the second air-processing apparatus operate simultaneously, or is driven in an independent operation mode in which only one of the first air-processing apparatus or the second air-processing apparatus operates, wherein the first air-processing apparatus and the second air-processing apparatus are different types of air-processing modules which are combined with each other so as to extend in a longitudinal direction, wherein the first air-processing apparatus comprises a first pre-filter disposed in the first inlet, wherein the second air-processing apparatus comprises a second pre-filter disposed in the second inlet, and wherein the first air-processing apparatus and the second air-processing apparatus are disposed adjacent to each other;
a guide rail disposed on one side of the first air-processing apparatus and one side of the second air-processing apparatus; and
a filter cleaner configured to automatically move along the guide rail when operation is stopped in order to clean at least one of the first pre-filter or the second pre-filter.
