Description

Air conditioning system Technical Field The present invention relates to an air conditioning system, and more particularly, to an air conditioning system including a plurality of air treatment devices. Background An air conditioning system includes an air conditioner or air cleaner that can adjust the temperature of a room or remove fine dust from the air in the room. In the case of an air conditioner, indoor units such as a vertical indoor unit, a wall-mounted indoor unit, and a ceiling-mounted indoor unit are disposed in an indoor space, and the temperature of the indoor space can be adjusted. The air purifier mainly has a structure of a floor movably disposed in an indoor space, and can purify polluted air in the indoor space. Since the air conditioner and the air cleaner are physically disposed apart from each other, there may be a difference between a region where the air conditioner discharges the heat-exchanged air and a region where the air cleaner discharges the filtered air. In order to solve such a problem, a filter may be disposed in the suction port region of the air conditioner. However, if a high-efficiency air filter for an air cleaner is provided to an air conditioner, resistance is generated to the flow of air flowing to a heat exchanger, and thus there is a problem in that it is difficult to use. Korean laid-open patent No. KR 2012-0034446 proposes a structure in which an additional air conditioner is disposed in a lower space of a vertical air conditioner. However, in the case of such a structure, although it is suitable for performing air conditioning to a space separated into a lower side region and an upper side region, there is a problem in that it is difficult to perform temperature conditioning and air purification in the overlapped space. The air treatment device disposed in the ceiling of the indoor space has a structure in which the suction port and the discharge port are opened downward. Korean laid-open patent No. KR 10-2009-0081607 discloses a ceiling-mounted air treatment device. In this structure, in order to replace the filter disposed at the suction port, there is a difficulty in that the user needs to directly replace the filter at the ceiling. Korean laid-open patent No. 10-2020-0144534 discloses a structure in which a filter attached to a suction panel is moved downward together with the suction panel by means of a wire or the like. However, there is a problem in that even with such a structure, it is necessary to move the individual panels together in order to replace the filter. Disclosure of Invention The present invention provides an air conditioning system for supplying air with temperature-regulated air and air with air purified to an indoor space at the same time. A further object of the present invention is to provide an air conditioning system capable of rapidly circulating temperature-regulated air and filtered air indoors. Another object of the present invention is to provide an air conditioning system including an air treatment device capable of maximally utilizing a discharge port area. Another object of the present invention is to provide an air conditioning system capable of maintaining a clean state of a pre-filter disposed in a plurality of air treatment devices. The invention provides an air conditioning system which enables a user to easily replace a filter mounted in an air treatment device arranged on a ceiling. Another object of the present invention is to provide an air conditioning system including an air treatment device, which is stably disposed in a filter device disposed in a casing. Another object of the present invention is to provide an air conditioning system including an air treatment device, which can stably move a bottom cover that moves so as to cover the lower side of a filter device or the lower side of a discharge port. The problems of the present invention are not limited to the above-mentioned problems, and other problems not mentioned can be clearly understood by those skilled in the art from the following description. In order to achieve the above object, an air conditioning system according to an embodiment of the present invention includes a first air treatment device having a first outlet opening to a floor surface and a first inlet opening in a direction inclined to a direction of the first outlet opening, and performing heat exchange of air flowing in through the first inlet opening to the first outlet opening, and a second air treatment device having a second outlet opening in a direction parallel to the first outlet opening and a second inlet opening in a direction parallel to the first inlet opening, and performing filtration of air flowing into the second inlet opening to the second outlet opening, thereby performing temperature adjustment of an indoor space and air purification of the indoor space at the same time. Further, each of the first and second discharge ports extends in the left-right direction, and the firs
