Description

[Technical Field]

[0001] This invention relates to a heat exchange air conditioning device, and more particularly to a heat exchange air conditioning device. [Previous Technology]

[0002] Previously, indoor spaces were designed with high airtightness, high thermal insulation, and high sound insulation to block outdoor air pollution. While this achieved the goal of blocking outdoor air pollution, it also caused a decline in indoor air quality because the indoor space could not circulate with the outdoors. Poor indoor air quality easily breeds bacteria and mold. If furniture or building materials contain volatile chemicals such as ammonia or formaldehyde, it will seriously affect human health, especially for people who spend most of their time indoors.

[0003] Although most enclosed spaces are equipped with air conditioning systems, these systems only recycle indoor air and cannot exhaust indoor air or introduce fresh outdoor air, resulting in stale indoor air remaining trapped. Therefore, a heat exchanger is needed to exhaust stale indoor air and harmful substances and introduce fresh outdoor air to improve indoor air quality. However, installing heat exchangers alongside air conditioning systems often presents inconveniences in pipework configuration and increases pipework complexity. If a wall-mounted heat exchanger is installed alongside the indoor unit of the air conditioner, it will reduce the living space and activity area. [Summary of the Invention]

[0004] Therefore, the object of the present invention is to provide a space-saving and easy-to-install heat exchange air conditioning device.

[0005] Therefore, the heat exchange air conditioning equipment of the present invention includes a housing, a heat exchange device, an air conditioning device, an air conditioning air duct, an air exchange exhaust air duct, and a circulating air duct.

[0006] The housing includes an outer shell and a partition structure disposed inside the outer shell. The partition structure includes a partition plate, a first partition plate, a second partition plate, a third partition plate, a partition plate, and a support plate. The partition plate connects to the outer shell and extends along a first direction. The first partition plate is disposed between the outer shell and the partition plate. The second partition plate forms two ventilation holes and is spaced apart from the first partition plate along the first direction. The third partition plate is spaced apart from the second partition plate along the first direction and is located on the opposite side of the second partition plate. The partition plate connects the first partition plate, the second partition plate, and the third partition plate between the ventilation holes, extends along the first direction, and connects the outer shell and the partition plate. The support plate connects the partition plate and the outer shell and extends along a second direction perpendicular to the first direction, and forms at least one ventilation hole.

[0007] The heat exchange device includes an air inlet formed on the first partition, an air outlet formed on the outer shell and spaced apart from the air inlet, a circulation inlet formed on the first partition and spaced apart from the air inlet, a circulation outlet formed on the third partition and spaced apart from the circulation inlet, two heat exchange fans respectively disposed on opposite sides of the partition and respectively aligned with the ventilation holes, and a heat exchanger disposed between the second partition and the third partition.

[0008] The air conditioning device includes an air conditioning inlet formed on the outer casing, an air conditioning outlet formed on the outer casing and spaced apart from the air conditioning inlet, at least one air conditioning fan disposed on the support plate and aligned with the ventilation hole, and an evaporator disposed between the air conditioning outlet and the support plate.

[0009] The air conditioning air duct is defined by at least the air conditioning inlet, the air conditioning fan, the vent, the evaporator and the air conditioning outlet, and guides the airflow through the air conditioning device.

[0010] The ventilation exhaust path is defined at least by the ventilation inlet, one of the heat exchange fans, one of the ventilation holes, the heat exchanger, and the ventilation outlet. The ventilation exhaust path is used to exhaust indoor air to the outside.

[0011] The circulating air path is defined at least by the circulating air inlet, another of the heat exchange fans, another of the ventilation holes, the heat exchanger, the circulating air outlet, and the air conditioning outlet. The circulating air path is used to supply outdoor air to the room.

[0012] In some embodiments, the heat exchange device further includes three dampers, which are respectively disposed at the air exchange inlet, the circulation inlet and the circulation outlet. When the heat exchange air conditioning equipment is set to heat exchange mode, the dampers are opened and the heat exchange fans are turned on, so that the airflow flows to the air exchange outlet and the circulation air path.

[0013] In some embodiments, the heat exchange device further includes three dampers, which are respectively disposed at the air exchange inlet, the circulation inlet and the circulation outlet. When the heat exchange air conditioning equipment is set to air conditioning mode, the dampers are closed and the air conditioning fans are turned on, so that the airflow flows to the air conditioning air path.

[0014] In some embodiments, the heat exchange device further includes three dampers, which are respectively disposed at the air exchange inlet, the circulation inlet and the circulation outlet. When the heat exchange air conditioning equipment is set to the heat exchange air conditioning mode, the dampers are opened and the heat exchange fan and the air conditioning fan are turned on, so that the airflow flows to the air exchange outlet, the circulation air path and the air conditioning air path.

[0015] In some embodiments, the heat exchanger has several layers of thin films that are stacked such that the airflow in the ventilation outlet path and the airflow in the circulation path that flow through the heat exchanger simultaneously do not flow into each other.

[0016] In some embodiments, the heat exchanger has a hexagonal cross-section.

[0017] In some embodiments, the heat exchange fans share a motor, each heat exchange fan has a blade, and the blades are respectively disposed on opposite sides of the motor and on opposite sides of the partition.

[0018] In some embodiments, the evaporator is tilted from the support plate toward the air conditioning outlet.

[0019] The advantages of this invention are: by integrating the heat exchange device and the air conditioning device together inside the casing, the convenience of construction is increased and the construction configuration of pipelines is simplified. Furthermore, by sharing some parts among the air conditioning duct, the ventilation exhaust duct, and the circulating duct, the number of pipes is reduced.

Implementation Method

[0020] Referring to Figures 1 and 2, an embodiment of the heat exchange air conditioning equipment of the present invention includes a housing 1, a heat exchange device 2, an air conditioning device 3, an air conditioning air duct 4, an air exchange exhaust air duct 5, and a circulating air duct 6.

[0021] The housing 1 includes an outer shell 11 and a partition structure 12 disposed inside the outer shell 11. The partition structure 12 includes a partition plate 121, a first partition plate 122, a second partition plate 123, a third partition plate 124, a partition plate 125, and a support plate 126. The partition plate 121 connects to the outer shell 11 and extends back and forth along a first direction X. The first partition plate 122 is disposed between the outer shell 11 and the partition plate 121 and extends along a second direction Y perpendicular to the first direction X. The second partition plate 123 forms two ventilation holes 127 vertically and is spaced back and forth from the first partition plate 122 along the first direction X, and extends along the second direction Y. The third partition plate 124 is spaced back and forth from the second partition plate 123 along the first direction X, and is located on the opposite side of the second partition plate 123 from the first partition plate 122, and extends along the second direction Y. The partition 125 connects the first partition 122, the second partition 123, and the third partition 124 between the ventilation holes 127, and extends back and forth along the first direction X, connecting the outer casing 11 and the partition 121. This divides the space defined by the casing 1, the partition 121, the first partition 122, and the second partition 123 into two vertically separated sub-spaces. The support plate 126 connects the partition 121 and the outer casing 11 and extends left and right along the second direction Y, forming two spaced-apart ventilation holes 128. In this embodiment, the support plate 126 is connected to the third partition 124.

[0022] The heat exchange device 2 includes an air inlet 21 formed on the first partition 122, an air outlet 22 formed on the outer shell 11 and spaced apart from the air inlet 21, a circulation inlet 23 formed on the first partition 122 and spaced vertically from the air inlet 21, a circulation outlet 24 formed on the third partition 124 and spaced vertically from the circulation inlet 23, two heat exchange fans 26 respectively disposed on opposite upper and lower sides of the partition 125 and respectively aligned with the ventilation holes 127, a heat exchanger 25 disposed between the second partition 123 and the third partition 124, and three dampers 27 respectively disposed on the air inlet 21, the circulation inlet 23 and the circulation outlet 24.

[0023] In this embodiment, the heat exchange fans 26 share a single motor 261. Each heat exchange fan 26 has a blade 262. The blades 262 are respectively disposed on opposite upper and lower sides of the motor 261 and on opposite upper and lower sides of the partition 125. Compared with installing only one fan in the heat exchange device 2, the above embodiment has a larger air volume, and the fact that the heat exchange fans 26 share a single motor 261 reduces the volume compared with the fact that the heat exchange fans 26 are driven by different motors, thereby increasing the air volume and taking into account space utilization efficiency.

[0024] In this embodiment, the heat exchanger 25 has several layers of stacked thin films forming a fin-like structure. These thin films allow airflow to the outside and airflow to the inside to exchange heat energy using the thermal conductivity of gas flow without mutual flow. Therefore, these thin films can balance the temperature of the airflow to the outside and the airflow to the inside, and simultaneously balance the humidity of the airflow to the outside and the airflow to the inside. Specifically, in this configuration of the heat exchanger 25, when air flows into the heat exchanger 25 through the upper vent 127, it flows obliquely downward based on the structure of the thin films and exits from the circulation outlet 24. On the other hand, when air flows into the heat exchanger through the lower vent 127, it flows obliquely upward based on the structure of the thin films and exits from the ventilation outlet 22. During the above process, the air flowing through the heat exchanger 25 from different paths will not mix, but can be guided by the internal structure of the heat exchanger 25 to carry out the aforementioned heat exchange and humidity regulation processes respectively.

[0025] In this embodiment, the heat exchanger 25 has a hexagonal cross-section. Under the same height and width conditions, the surface area of ​​the hexagonal heat exchanger in contact with air is larger than that of the quadrilateral heat exchanger. Therefore, the heat exchange efficiency of the hexagonal heat exchanger is higher than that of the quadrilateral heat exchanger, which is the preferred implementation method in this embodiment. However, its specific shape can be configured as needed and is not limited to a specific form.

[0026] The air conditioning unit 3 includes an air conditioning inlet 31 formed on the outer casing 11, an air conditioning outlet 32 ​​formed on the outer casing 11 and spaced apart from the air conditioning inlet 31, two air conditioning fans 33 disposed on the support plate 126 and respectively aligned with the ventilation holes 127, and an evaporator 34 disposed between the air conditioning outlet 32 ​​and the support plate 126. The evaporator 34 is inclined from the support plate 126 toward the air conditioning outlet 32 ​​to increase the surface area in contact with the airflow.

[0027] Referring to Figure 3, the air conditioning air duct 4 is defined by at least the air conditioning air inlet 31, the air conditioning fan 33, the ventilation holes 128, the evaporator 34 and the air conditioning air outlet 32, and guides the airflow through the air conditioning device 3, so that the indoor air circulates in the room.

[0028] Referring to Figure 4, the ventilation exhaust path 5 is defined at least by the ventilation inlet 21, one of the heat exchange fans 26, one of the ventilation holes 127, the heat exchanger 25, and the ventilation outlet 22. The ventilation exhaust path 5 is used to exhaust indoor air to the outside. The recirculation path 6 is defined at least by the recirculation inlet 23, the other of the heat exchange fans 26, the other of the ventilation holes 127, the heat exchanger 25, the recirculation outlet 24, and the air conditioning outlet 32. The recirculation path 6 is used to supply outdoor air to the indoor environment.

[0029] Referring to Figures 2 to 4, according to the above configuration, the heat exchange air conditioning equipment can be used in heat exchange mode, air conditioning mode, and heat exchange air conditioning mode according to the user's needs. When the heat exchange air conditioning equipment is set to heat exchange mode, the dampers 27 are open and the heat exchange fans 26 are turned on, while the air conditioning fans 33 are turned off at the same time. The heat exchange fans 26 are turned on so that indoor polluted air flows into the ventilation outlet 5 through the ventilation inlet 21 and is discharged to the outside through the ventilation outlet 22; and at the same time, outdoor fresh air flows into the circulation duct 6 through the circulation inlet 23 and then flows through the air conditioning outlet 32 ​​through the circulation outlet 24 to supply the room. In addition, when indoor polluted air and outdoor fresh air flow through the heat exchanger 25, the indoor polluted air flowing through the ventilation outlet 5 and the outdoor fresh air flowing through the circulation duct 6 will not circulate with each other. Outdoor fresh air and indoor stale air will exchange heat and moisture with each other in the heat exchanger 25.

[0030] When the heat exchange air conditioning equipment is set to air conditioning mode, the dampers 27 are closed and the air conditioning fans 33 are turned on, while the heat exchange fans 26 are turned off at the same time. The turning on of the air conditioning fans 33 causes indoor air to flow through the air conditioning inlet 31 to the air conditioning duct 4, and the indoor air is cooled down by the evaporator 34. Finally, the cooled indoor air is discharged from the air conditioning outlet 32, achieving the effect of reducing the indoor temperature. In this air conditioning mode, only indoor air is circulated within the room, and air is not allowed to circulate between the indoor and outdoor environments.

[0031] When the heat exchange air conditioning equipment is set to heat exchange air conditioning mode, the dampers 27 open, and the heat exchange fans 26 and the air conditioning fans 33 turn on. The operation of the heat exchange fans 26 and the air conditioning fans 33 causes indoor air to flow to the ventilation exhaust duct 5 and the air conditioning duct 4, respectively. A portion of the indoor air enters the ventilation exhaust duct 5 and flows through the heat exchanger 25 to be discharged outdoors; another portion of the indoor air enters the air conditioning duct 4 and flows through the evaporator 34 to lower its temperature, and finally enters the room through the air conditioning outlet 32. Simultaneously, the heat exchange fans 26 turn on, causing outdoor air to enter the circulation duct 6 and flow through the heat exchanger 25, resulting in heat exchange and humidity balance between the outdoor and indoor air. Then, the outdoor air merges with the indoor air in the air conditioning unit 3 through the circulation outlet 24, and finally, both the outdoor air and the indoor air in the air conditioning unit 3 enter the room through the air conditioning outlet 32. In this heat exchange air conditioning mode, the air flowing out of the air conditioner outlet 32 ​​includes both indoor air and indoor air introduced from the outside. Therefore, the air volume at the air conditioner outlet 32 ​​will be greater than the air volume in this heat exchange mode or this air conditioning mode.

[0032] In summary, the heat exchange air conditioning equipment of the present invention integrates the heat exchange device 2 and the air conditioning device 3 inside the casing 1, thereby increasing the convenience of construction and simplifying the construction and piping configuration. Furthermore, by sharing some parts with the air conditioning air duct 4, the ventilation exhaust air duct 5, and the circulating air duct 6, the number of piping components is reduced, thus effectively achieving the purpose of the present invention.

Any simple equivalent changes and modifications made in accordance with the scope of the patent application and the contents of the patent specification of the present invention shall still fall within the scope of the patent of the present invention.
