Referring to
The air conditioning unit 40 includes a compressor (not shown), an expansion valve (not shown), a four-way valve (not shown), a first heat exchanger 42, and a second heat exchanger 44, which constitute a heat pump cycle. Although not shown, the compressor, the expansion valve, and the four-way valve may be disposed between the first heat exchanger 42 and the second heat exchanger 44.
The first heat exchanger 42 and the second heat exchanger 44 are installed vertically over the two-story suction channels.
Regardless of whether air is introduced through the 1-1 suction channel 54-1 or the 1-2 suction channel 54-2, therefore, the air may exchange heat with the entire surface of the first heat exchanger 42 or the second heat exchanger 44.
In the same manner, regardless of whether air is introduced through the 2-1 suction channel 56-1 or the 2-2 suction channel 56-2, therefore, the air may exchange heat with the entire surface of the first heat exchanger 42 or the second heat exchanger 44.
That is, even when air is introduced through only one story of each of the two-story suction channels, the air exchanges heat with the entire surface of the first heat exchanger 42 or the second heat exchanger 44, which is installed vertically over a corresponding one of the two-story suction channels.
In this embodiment, the first heat exchanger 42 or the second heat exchanger 44 are used in common for the multiple channels as defined above.
The first heat exchanger 42 may function as an evaporator or a condenser. The surface of the first heat exchanger 42 is coated with a desiccant material such that moisture clings to the surface of the first heat exchanger 42.
The second heat exchanger 44 may function as a condenser or an evaporator, and may be unlike the first heat exchanger 42. The surface of the second heat exchanger 44 is also coated with a desiccant material such that moisture clings to the surface of the second heat exchanger 44.
The desiccant material is a material that is capable of absorbing moisture from the air and discharging the absorbed moisture into the air when heat is applied to the desiccant material. The desiccant material is well known to those skilled in the art, and therefore a detailed description thereof will be omitted.
In this embodiment, the first and second heat exchangers 42 and 44 are alternately used as condensers or evaporators according to the heat pump cycle. When the first and second heat exchangers 42 and 44 are used as evaporators, the first and second heat exchangers 42 and 44 absorb moisture. When the first and second heat exchangers 42 and 44 are used as condensers, on the other hand, the first and second heat exchangers 42 and 44 discharge absorbed moisture into the air.
In this embodiment, the first heat exchanger 42 is disposed in a first heat exchanger housing 45, and the second heat exchanger 44 is disposed in a second heat exchanger housing 46.
The first heat exchanger housing 45 is connected between the first suction channel 54 and the first discharge channel 64. The second heat exchanger housing 46 is connected between the second suction channel 56 and the second discharge channel 66.
Air flowing from the suction channel module 50 to the discharge channel module 60 passes through the first heat exchanger housing 45 or the second heat exchanger housing 46. At this time, the air exchanges heat with the first heat exchanger 42, which is disposed in the first heat exchanger housing 45, or the second heat exchanger 44, which is disposed in the second heat exchanger housing 46.
Hereinafter, the operation of the air conditioner apparatus according to the first embodiment of the present invention will be described in detail.
First, a circulation mode, in which air suctioned from the outdoors is discharged to the outdoors and air suctioned from the indoors is discharged to the indoors, will be described in detail. The circulation mode is shown in
In the circulation mode, a course along which indoor air passes through the first heat exchanger 42 and a course along which indoor air passes through the second heat exchanger 44 are defined.
The circulation mode include a first circulation mode, in which air flows straight, and a second circulation mode, in which air passes through the suction connection channel 57 or the discharge connection channel 67.
In the first circulation mode, the air in the first suction channel 54 flows to the first discharge channel 64 and the air in the second suction channel 56 flows to the second discharge channel 66.
In the first circulation mode, indoor air may be humidified or dehumidified. That is, a humidification mode or a dehumidification mode may be applied.
In the first circulation mode, the first suction damper 58 and the second suction damper 59 close the suction connection channel 57, and the first discharge damper 68 and the second discharge damper 69 close the discharge connection channel 67.
In the first circulation mode, indoor air and outdoor air flow straight. When the air flows straight, air resistance is minimized. At this time, the air uniformly exchanges heat with the entire surface of the first heat exchanger 42 or the second heat exchanger 44.
When the air exchanges heat with the first heat exchanger 42 or the second heat exchanger 44, the air does not exchange heat only with a portion of the first heat exchanger 42 or the second heat exchanger 44, but uniformly exchanges heat with the entire surface of the first heat exchanger 42 or the second heat exchanger 44, which are installed over the first and second stories of a corresponding one of the suction channels.
The flow of air during the outdoor suction and outdoor discharge by the air conditioner apparatus and during the indoor suction and indoor discharge by the air conditioner apparatus as described above may be summarized as follows using only reference numerals (the first circulation mode, shown in
(1) The flow of air during the outdoor suction and outdoor discharge by the air conditioner apparatus
54->42->64
(2) The flow of air during the indoor suction and indoor discharge by the air conditioner apparatus
56->44->66
Meanwhile, in this embodiment, air may be guided to the suction connection channel 57 or the discharge connection channel 67 using the suction dampers 58 and 59 and the discharge dampers 68 and 69, whereby the first and second heat exchangers 42 and 44, which exchange heat with the air, may be alternately used.
The flow of air during the outdoor suction and outdoor discharge by the air conditioner apparatus and during the indoor suction and indoor discharge by the air conditioner apparatus using the suction connection channel 57 and the discharge connection channel 67 may be summarized as follows using only reference numerals (the second circulation mode, shown in
(3) The flow of air during the outdoor suction and outdoor discharge by the air conditioner apparatus using the suction connection channel 57 and the discharge connection channel 67
54->57-2->44->66-1->67-1->64-1
(4) The flow of air during the indoor suction and indoor discharge by the air conditioner apparatus using the suction connection channel 57 and the discharge connection channel 67
56->57-1->42->64-2->67-2->66-2
Even when air flows through the connection channels 57 and 67, the air exchanges heat with the entire surface of the first heat exchanger 42 or the second heat exchanger 44.
In the second circulation mode, the air may flow between the stories of each of the channels.
During the outdoor suction and outdoor discharge or the indoor suction and indoor discharge by the air conditioner apparatus according to this embodiment, the second heat exchanger 44 may be operated as the evaporator when the first heat exchanger 42 is operated as the condenser, and the second heat exchanger 44 may be operated as the condenser when the first heat exchanger 42 is operated as the evaporator.
For example, in order to dehumidify indoor air, the second heat exchanger 44 is used as the evaporator in air flow course (2). After air flow course (2) is maintained for a predetermined period of time, moisture clings to the second heat exchanger 44, with the result that the dehumidification performance of the second heat exchanger 44 is reduced.
At this time, the operation mode of the air conditioning unit 40 is changed such that the second heat exchanger 44 operates as the condenser and the first heat exchanger 42 operates as the evaporator.
In this case, the air flow course is changed from air flow course (2) to air flow course (4) such that air suctioned from the indoors and discharged to the indoors exchanges heat with the first heat exchanger 42, which operates as the evaporator, whereby indoor air is continuously dehumidified.
On the other hand, in order to humidify indoor air, heat exchange may be carried out between air flowing into the indoors and the heat exchangers 42 and 44 operating as the condensers such that moisture is supplied to the air.
In this embodiment, a mode in which the straight channels are closed and connection channels 57 and 67 are opened using the dampers 58, 59, 68, and 69 is defined as a first mode.
On the other hand, a mode in which the straight channels are opened and connection channels 57 and 67 are closed using the dampers 58, 59, 68, and 69 is defined as a second mode.
The suction channel module 50 and the discharge channel module 60 may be operated in the first mode or in the second mode.
In air flow courses (1) and (2), both the suction channel module 50 and the discharge channel module 60 may be operated in the second mode. On the other hand, in air flow courses (3) and (4), both the suction channel module 50 and the discharge channel module 60 may be operated in the first mode.
Next, a ventilation mode, in which the outdoor suction and indoor discharge or the indoor suction and outdoor discharge by the air conditioner apparatus are carried out, will be described in detail.
In the ventilation mode, outdoor air is supplied to the indoors, and some indoor air is discharged to the outdoors, such that air-conditioned air, i.e. fresh air, is supplied to the indoors.
In this embodiment, therefore, during the outdoor suction and indoor discharge by the air conditioner apparatus, outdoor air is suctioned through the first suction channel 54, and then air is discharged through the second discharge channel 66.
In addition, during the indoor suction and outdoor discharge by the air conditioner apparatus, indoor air is suctioned through the second suction channel 56, and then air is discharged through the first discharge channel 64.
Both during the outdoor suction and indoor discharge by the air conditioner apparatus and during the indoor suction and outdoor discharge by the air conditioner apparatus, air flows through the connection channels, and two courses may be selected in each case.
In the ventilation mode according to this embodiment, air passes through at least one selected from between the suction connection channel 57 and the discharge connection channel 67.
The flow of air during the outdoor suction and indoor discharge by the air conditioner apparatus and during the indoor suction and outdoor discharge by the air conditioner apparatus as described above may be summarized as follows using only reference numerals.
(5) The flow of air during the outdoor suction and indoor discharge by the air conditioner apparatus
54->42->64-2->67-2->66-2
(6) The flow of air during the outdoor suction and indoor discharge by the air conditioner apparatus
56->57-2->44->66
(7) The flow of air during the indoor suction and outdoor discharge by the air conditioner apparatus
56->44->66-1->67-1->64-1
(8) The flow of air during the indoor suction and outdoor discharge by the air conditioner apparatus
56->57-1->42->64
In air flow courses (5) and (7), heat exchange is carried out between the suctioned air and the heat exchangers, and then the air is discharged through the connection channels. In air flow courses (6) and (8), on the other hand, the suctioned air passes through the connection channels, heat exchange is carried out between the air and the heat exchangers, and then the air is discharged.
In air flow course (5), outdoor air flows straight through the first suction channel 54 and the first heat exchanger 42, passes through the connection channel, and is discharged to the indoors.
In air flow course (7), outdoor air is suctioned through the first suction channel 54, passes through the connection channel, and exchanges heat with the second heat exchanger 44. The heat-exchanged air flows straight, and is then discharged to the indoors.
In air flow course (6), indoor air flows straight through the second suction channel 56 and the second heat exchanger 44, passes through the connection channel, and is discharged to the outdoors.
In air flow course (8), indoor air is suctioned through the second suction channel 56, passes through the connection channel, and exchanges heat with the first heat exchanger 42. The heat-exchanged air flows straight, and is then discharged to the outdoors.
Meanwhile, the above may be described as follows in terms of the suction channel module 50 and the discharge channel module 60.
In air flow courses (5) and (7), the suction channel module 50 is operated in the second mode, and the discharge channel module 60 is operated in the first mode.
In air flow courses (6) and (8), the suction channel module 50 is operated in the first mode, and the discharge channel module 60 is operated in the second mode.
That is, in the air conditioner apparatus according to this embodiment, the dampers of the suction channel module 50 and the discharge channel module 60 are controlled to be operated in groups in the first mode or in the second mode rather than being individually controlled.
When the air conditioner apparatus according to this embodiment is operated in the ventilation mode, one may be selected from between the first heat exchanger 42 and the second heat exchanger 44 such that the selected heat exchanger exchanges heat with air.
For example, in order to dehumidify air supplied from the outdoors to the indoors, the first heat exchanger 42 may be operated as the evaporator in air flow course (5), and the second heat exchanger 44 may be operated as the evaporator in air flow course (6).
If the dehumidification performance of the first heat exchanger 42 is reduced after the first heat exchanger 42 is operated as the evaporator in air flow course (5), the heat pump cycle of the air conditioning unit 40 may be changed such that the second heat exchanger 44 is operated as the evaporator, and the air flow course may be changed from air flow course (5) to air flow course (6), whereby it is possible to continuously dehumidify air supplied from the outdoors to the indoors.
For humidification, on the other hand, the first heat exchanger 42 may be operated as the condenser in air flow course (5), and the second heat exchanger 44 may be operated as the condenser in air flow course (6).
As described above, the air conditioner apparatus according to this embodiment has the effect of changing the air flow course through the opening and closing operations of the dampers 58, 59, 68, and 69 such that the dehumidification or humidification of air can be continuously carried out in the ventilation mode.
Meanwhile, in this embodiment, both the suction channel module 50 and the discharge channel module 60 are configured to have a two-story structure. Unlike this embodiment, however, one selected from between the suction channel module 50 and the discharge channel module 60 may be configured to have a multi-story structure, and the other selected from between the suction channel module 50 and the discharge channel module 60 may be configured to have a single-story structure.
In addition, in this embodiment, the suction channel module 50 and the discharge channel module 60 respectively include a plurality of suction channels 54 and 56, which extends in leftward and rightward directions, and a plurality of discharge channels 64 and 66, which extends in leftward and rightward directions. Unlike this embodiment, the suction channel module 50 and the discharge channel module 60 may each include a single suction channel and a single discharge channel. In this case, the suction channel module 50 may include an outdoor suction-side suction channel module and an indoor suction-side suction channel module, and the discharge channel module 60 may include an outdoor discharge-side discharge channel module and an indoor discharge-side discharge channel module.
As is apparent from the above description, the air conditioner apparatus according to the present invention has at least one of the following effects.
First, regardless of whether air is introduced through the upper part or the lower part of the suction channel, the air exchanges heat with the heat exchanger while contacting the entire surface of the heat exchanger. Consequently, it is possible to perform heat exchange using the entire surface of the heat exchanger, irrespective of the suction area.
Second, the suction channel module and the discharge channel module have the same structure. Consequently, it is possible to easily install and repair the air conditioner apparatus.
Third, the suction channel module and the discharge channel module are operated in the first mode or in the second mode. Consequently, it is possible to execute both the circulation mode and the ventilation mode.
Fourth, the heat exchanger is installed so as to have an area greater than the sectional area of the suction channels, which are disposed one above the other.
Consequently, it is possible to maximize the heat exchange area irrespective of the suction sectional area.
Fifth, the sectional area of the heat exchanger housing is greater than that of the suction channels, which are disposed one above the other. Consequently, it is possible to reduce the flow speed of air, thereby increasing the time during which heat exchange between air and the heat exchanger is performed.
It will be apparent that, although the embodiments of the present invention have been described above with reference to the accompanying drawings, the present invention is not limited to the above-described specific embodiments, and therefore various modifications and variations can be made by those skilled in the art without departing from the gist of the appended claims. Thus, it is intended that the modifications and variations should not be understood independently of the technical spirit or prospect of the present invention.
