Description

Technical Field

[0001] This invention relates to air conditioning systems, and more specifically, to an air conditioning system comprising a plurality of air handling units. Background Technology

[0002] Air conditioning systems include air conditioners or air purifiers, which can regulate indoor temperature or remove dust particles from indoor air.

[0003] In the case of air conditioners, indoor units such as floor-standing indoor units, wall-mounted indoor units, and ceiling-mounted indoor units are installed in the indoor space to regulate the temperature of the indoor space.

[0004] Air purifiers are mainly structured to be movable and installed on the floor of an indoor space, and can purify polluted air in the indoor space.

[0005] Because air conditioners and air purifiers are physically separated from each other, the areas where air conditioners discharge heat-exchanged air and the areas where air purifiers discharge filtered air may differ.

[0006] To address this issue, a filter can be installed in the air conditioner's intake area. However, if a high-efficiency air filter, typically used in air purifiers, is installed in an air conditioner, it creates resistance to the airflow towards the heat exchanger, making it difficult to use.

[0007] Korean Patent Publication No. KR 2012-0034446 proposes a structure in which an additional air conditioner is arranged in the lower space of a vertical air conditioner. However, while this structure is suitable for performing air conditioning on spaces separated into lower and upper regions, it presents the problem of difficulty in performing temperature regulation and air purification in overlapping spaces.

[0008] Furthermore, the air handling unit installed on the ceiling of the indoor space has a structure where the inlet and outlet open downwards. Korean Patent Publication No. KR 10-2009-0081607 discloses an air handling unit installed on the ceiling. In this structure, there is a difficulty in replacing the filter located at the inlet, requiring the user to replace the filter directly on the ceiling.

[0009] Korean Patent Publication No. 10-2020-0144534 discloses a structure that uses steel wire or the like to move a filter installed on an inhalation panel downwards together with the inhalation panel.

[0010] However, the problem is that even with this structure, a separate panel needs to be moved along with the filter in order to replace it. Summary of the Invention

[0011] The problem to be solved by the present invention is to provide an air conditioning system that simultaneously supplies temperature-regulated air and purified air to an indoor space.

[0012] Another objective of this invention is to provide an air conditioning system capable of rapidly circulating temperature-regulated and filtered air indoors.

[0013] Another objective of the present invention is to provide an air conditioning system comprising an air handling unit capable of maximizing the utilization of the outlet area. Yet another objective of the present invention is to provide an air conditioning system capable of maintaining the cleanliness of pre-filters disposed in a plurality of air handling units.

[0014] The present invention provides an air conditioning system in which the user can easily replace the filter installed in an air handling unit configured in the ceiling.

[0015] Another objective of the present invention is to provide an air conditioning system including an air handling device, wherein a filter device is stably disposed in a housing.

[0016] Another objective of the present invention is to provide an air conditioning system including an air handling device, which enables a bottom cover that moves in a manner that covers the lower side of a filter or the lower side of an outlet to move stably.

[0017] The subject matter of this invention is not limited to the subject matter mentioned above, and those skilled in the art can clearly understand other subject matters not mentioned through the following description.

[0018] To achieve the aforementioned objectives, the air conditioning system of this invention includes: a first air handling device having a first discharge port opening towards the ground and a first intake port opening in a direction inclined to the direction of the first discharge port opening, for heat exchange of air flowing in through the first intake port and delivery to the first discharge port; and a second air handling device having a second discharge port opening in a direction parallel to the first discharge port and a second intake port opening in a direction parallel to the first intake port, for filtering air flowing into the second intake port and delivery to the second discharge port, thereby enabling simultaneous temperature regulation and air purification of the indoor space. Furthermore, each of the first and second discharge ports extends in a left-right direction, and the first and second air handling devices are arranged in a left-right direction, thereby enabling temperature regulation and air purification of a designated area of ​​the indoor space.

[0019] The second outlet is arranged in the direction extending from the first outlet, so that the area for performing temperature change and the area for performing air purification are arranged adjacent to each other, thereby enabling simultaneous air conditioning and air purification of the respective areas.

[0020] The first air handling device includes a first louver that adjusts the flow direction of air discharged through the first outlet. The second air handling device includes a second louver that adjusts the flow direction of air discharged through the second outlet. The first louver and the second louver operate independently and can adjust the discharge direction separately, taking into account the temperature of the discharged air.

[0021] In each of the first and second louvers, a louver rotation axis is formed in front of the first and second discharge outlets, respectively. A plurality of blades are arranged radially along the louver rotation axis, which can cause air to be discharged towards the lower side or in front of the first and second discharge outlets.

[0022] The system includes a first louver drive device that drives the first louver and a second louver drive device that drives the second louver. Each of the first and second louver drive devices is configured to engage with the first and second louvers respectively at positions radially spaced from the louver rotation axis. That is, the louver drive devices are not located at the two ends of the blades, thus allowing the louvers to be positioned at both ends of the outlet. This maximizes the utilization of the area formed by the outlet.

[0023] The first air handling unit includes a first pre-filter disposed at the first intake port to filter foreign objects in the air flowing through the first intake port. The second air handling unit includes a second pre-filter disposed at the second intake port to filter foreign objects in the air flowing through the second intake port. The air conditioning system includes a filter cleaner that moves on the first and second air handling units to remove foreign objects from the first and second pre-filters, thereby allowing the pre-filters disposed in the first and second air handling units to be cleaned by a single filter cleaner.

[0024] Each of the first and second air handling units is equipped with a guide rail to guide the movement of the filter cleaner, which can move on the first and second air handling units.

[0025] The first intake port and the second intake port are formed on one side of a surface formed in a direction perpendicular to the ground. The first pre-filter is configured to be led out from the first air handling unit in a downward direction, and the second pre-filter is configured to be led out from the second air handling unit in a downward direction, so that the first pre-filter and the second pre-filter can be led out downward respectively.

[0026] The guide rail is positioned above the first and second suction inlets. Therefore, the filter cleaning machine does not affect the extraction of the pre-filter.

[0027] Each of the first and second air handling units is provided with a support rail that supports the movement of the filter cleaner along the guide rail, thereby supporting the movement of the filter cleaner in the left-right direction.

[0028] The filter cleaner includes a sensor for confirming the position of the filter cleaner, and sensing objects that react to the sensor are arranged on the guide rail to confirm the position of the filter cleaner. The guide rail includes a plurality of the sensing objects spaced apart from each other along the direction extending from the guide rail, so that the filter cleaner can identify the position of each of the first air handling unit and the second air handling unit.

[0029] The first air handling unit includes a heat exchanger that exchanges heat between the air flowing in through the first intake and the refrigerant. The second air handling unit includes a filter that filters out foreign matter from the air flowing into the second intake. The first air handling unit regulates the temperature of the corresponding space, and the second air handling unit can filter the air in the corresponding space. Therefore, it is possible to simultaneously regulate the temperature and filter the air in the corresponding space.

[0030] The first air handling device includes: a first housing forming an outer shape; a first cover disposed inside the first housing to form an airflow path; and a first fan disposed inside the first cover to form airflow. The first housing includes: a first upper cover fixed to a ceiling; a first lower cover disposed below the first upper cover; a first rear cover forming the first intake port and on which a first pre-filter is installed; a first front cover spaced forward from the first rear cover; and a pair of first side covers disposed at both ends of the first lower cover, the lower end of the first front cover being spaced apart from the front end of the first lower cover to form the first exhaust port, thereby forming the first exhaust port in a direction perpendicular to the first intake port.

[0031] The air conditioning system includes: a first louver rotatably disposed on the first housing to adjust the airflow direction of the air discharged at the first outlet; and a first louver drive device to change the arrangement of the first louver, the first louver being rotatably disposed on the lower part of the front cover, the first louver drive device being disposed on the upper side of the first lower cover, such that the louver drive device is disposed at a position radially spaced from the rotation axis of the louver.

[0032] The first cover includes a first upper cover disposed above the first fan and a first lower cover disposed below the first fan. The first upper cover and the first lower cover form an exhaust guide that guides air flowing from the first fan toward the first exhaust outlet. Therefore, the first cover can guide the air flowing through the first fan toward the exhaust outlet equipped with louvers.

[0033] The first lower cover includes: a drain pan disposed on the lower side of the heat exchanger to collect condensate falling from the heat exchanger; and a drive device cover disposed in front of the drain pan, which protrudes upward from the first lower cover to form a space for arranging the first louver drive device, thereby collecting condensate falling from the heat exchanger and covering the area where the louver drive device is arranged.

[0034] The second air handling device includes: a second housing forming an outer shape; a second cover disposed inside the second housing to form an airflow path; and a second fan disposed inside the second cover to form airflow. The second housing includes: a second upper cover fixed to a ceiling; a second lower cover disposed below the second upper cover; a second rear cover forming a second intake port on which a filter is mounted; a second front cover spaced forward from the second rear cover; a pair of second side covers disposed at opposite ends of the second lower cover; and a second bottom cover configured to move along the front-rear direction below the second lower cover to be positioned below the filter or below the second exhaust port, the second bottom cover being movable along the front-rear direction to cover the second exhaust port or the lower side of the filter.

[0035] A filter mounting portion is provided on the inner side of the rear cover, allowing the arrangement of the filter device to move vertically. A filter drive device is provided on the second lower cover, allowing the filter device and the filter mounting portion to move vertically, thereby enabling the filter device to move downwards. This improves user convenience as a filter device installed inside an air handling unit mounted on the ceiling.

[0036] The second bottom cover is provided with a cover drive device that moves the second bottom cover in the front-back direction, thereby changing the arrangement of the second bottom cover.

[0037] An air handling unit includes: a housing; an outlet forming a downward opening and an inlet opening in a direction perpendicular to the outlet opening; a fan disposed inside the housing to create airflow from the inlet to the outlet; a filter disposed at the inlet to filter foreign matter in the air flowing into the inlet; and a filter mounting portion movably disposed in the housing, allowing the arrangement of the filter to be changed vertically, thereby moving the arrangement of the filter mounted on the housing disposed on the ceiling downwards, thereby improving user convenience. Detailed descriptions of other embodiments are provided in the accompanying drawings.

[0038] The air conditioning system according to the present invention has one or more of the following effects.

[0039] First, the advantage is that by arranging air handling units that emit temperature-regulated air and air handling units that emit filtered air side by side along the left and right directions, it is possible to simultaneously perform air purification and temperature regulation in the indoor space.

[0040] Secondly, the advantage is that since the first and second air handling units are arranged in the left-right direction, the louvers at each outlet are driven individually. Therefore, taking into account the temperature of the discharged air, the discharge direction can be adjusted individually, thereby accelerating the air circulation in the indoor space.

[0041] Third, the louvers at the outlet of each of the first and second air handling units have a louver rotation axis on the front side, and a louver drive device is arranged at a position radially spaced from the louver rotation axis. The advantage is that, since the louver drive device is not arranged in the left-right direction of the louvers, the louvers can be arranged in the entire left-right direction of the outlet, thereby maximizing the utilization of the outlet area for exhausting air.

[0042] Fourth, an advantage is that a single filter cleaner can be used to clean the pre-filters of each air handling unit, which is configured in the first and second air handling units, thus maintaining the cleanliness of each pre-filter.

[0043] Fifth, an advantage is that the filter unit located in the second air handling unit can be moved vertically by the filter drive unit, so the user can easily approach the filter unit.

[0044] Sixth, the suction inlet on the housing opens in a direction perpendicular to the discharge outlet, thus providing a structure that allows the filter disposed at the suction inlet to move only downwards. Furthermore, the filter device disposed on the housing is moved downwards via the filter mounting section, allowing the user to easily detach the filter device disposed on the housing mounted on the ceiling.

[0045] Seventh, with the fan running, the bottom cover is positioned below the filter device, thus ensuring the filter device can be stably fixed. This has the advantage of reliably filtering foreign matter from the air flowing into the air handling unit. The effects of this invention are not limited to those mentioned above; those skilled in the art will clearly understand other effects not mentioned from the description of the claims.
