[0001] The invention relates to a humidity control device and an air treatment system. Background Art

[0002] In the past, there was a humidity control device, which included a shell, the shell was provided with an air inlet and an air outlet opposite to each other, and an air flow path from the air inlet to the air outlet was provided in the shell, and a moisture permeable membrane and a heat exchanger were provided, the moisture permeable membrane adjusted the humidity of the air flow flowing through the air flow path, and the heat exchanger adjusted the temperature of the air flow flowing through the air flow path.

[0003] However, in the existing humidity control device, the air flow is poor and the pressure loss is large. Summary of the invention

[0004] The present invention is completed in view of the above-mentioned problems, and its purpose is to provide a humidity control device and an air treatment system, which are helpful to improve the flowability of air flow and reduce pressure loss.

[0005] In order to achieve the above-mentioned objectives, the present invention provides a humidity control device, comprising: a shell, the shell is provided with an air inlet and an air outlet relative to each other, and an air flow path is formed from the air inlet to the air outlet; a heat exchange component, the heat exchange component includes a heat exchange part, the heat exchange part is arranged on the air flow path, and is used to adjust the temperature of the air flow flowing through the heat exchange part; and a humidifying component, the humidifying component includes a humidifying part, the humidifying part is arranged on the air flow path and is located between the heat exchange part and the air outlet, and is used to adjust the humidity of the air flow flowing through the heat exchange part, the length direction of the heat exchange part and the length direction of the humidifying part are respectively horizontal directions, wherein, when viewed from above, the following relationship is satisfied: 0≤the distance between the center line of the heat exchange part and the center line of the humidifying part≤65mm, 0≤the distance between the center line of the air inlet and the center line of the humidifying part≤65mm.

[0006] Here, the “heat exchange section” refers to a portion where air flows through and can perform heat exchange, and the “humidification section” refers to a portion where air flows through and can perform humidification.

[0007] According to the humidity control device of the present invention, the following relationships are satisfied when viewed from above: 0≤the distance between the center line of the heat exchange section and the center line of the humidifying section≤65mm, 0≤the distance between the center line of the air inlet and the center line of the humidifying section≤65mm. Therefore, it is possible to ensure that the airflow flows smoothly in the airflow path, improve the fluidity of the airflow inside the humidity control device, reduce pressure loss, and the deviation between the center line of the air inlet and the center line of the humidifying section is small, which can ensure that the airflow flows smoothly and evenly through the humidifying section, thereby ensuring the humidification effect of the humidifying section.

[0008] Furthermore, in the humidity control device of the present invention, preferably, when viewed from above, the following relationship is satisfied: 0≤the distance between the center line of the air inlet and the center line of the heat exchanger≤20 mm.

[0009] The humidity control device according to the present invention satisfies the following relationship when viewed from above: 0≤the distance between the center line of the air inlet and the center line of the heat exchange part≤20mm. Therefore, it can further ensure that the airflow flows smoothly in the airflow path, improve the fluidity of the airflow inside the humidity control device, and reduce the pressure loss. In addition, the deviation between the center line of the air inlet and the center line of the heat exchange part is small, which can ensure that the airflow flows smoothly and evenly through the heat exchange part, thereby ensuring the heat exchange effect of the heat exchange part.

[0010] Furthermore, in the humidity control device of the present invention, preferably, in a plan view, the following relationship is satisfied: 0≤distance between a center line of the humidifying section and a center line of the air outlet≤20 mm.

[0011] According to the humidity control device of the present invention, the following relationship is satisfied: 0≤the distance between the center line of the humidifying section and the center line of the air outlet≤20mm. Therefore, the airflow flowing between the humidifying section and the air outlet can be restrained from generating vortices, thereby further improving the flowability of the airflow inside the humidity control device and reducing the pressure loss. Moreover, the humidified air can smoothly flow out of the air outlet, reducing the humidity loss.

[0012] Furthermore, in the humidity control device of the present invention, it is preferred that a center line of the air inlet is disposed within a range of the air outlet, and a center line of the air outlet is disposed within a range of the air inlet.

[0013] According to the humidity control device of the present invention, the center line of the air inlet is set within the range of the air outlet, and the center line of the air outlet is set within the range of the air inlet. Therefore, the flowability of the airflow inside the humidity control device is further improved, the pressure loss is reduced, and the performance of the whole machine is ensured.

[0014] In addition, in the humidity control device of the present invention, preferably, when viewed from above, the center line of the heat exchange unit is parallel to and not colinear with the center line of the humidification unit, the center line of the heat exchange unit overlaps with the center line of the air inlet, and the center line of the humidification unit overlaps with the center line of the air outlet.

[0015] According to the humidity control device of the present invention, when viewed from above, the center line of the heat exchange part and the center line of the humidification part are parallel and non-collinear, the center line of the heat exchange part overlaps with the center line of the air inlet, and the center line of the humidification part overlaps with the center line of the air outlet. Therefore, the flowability of the airflow inside the humidity control device is further improved, the heat exchange capacity of the heat exchange component can be improved, thereby achieving energy saving. On the other hand, the capacity of the humidification component can be improved, thereby improving the humidification efficiency, and the design freedom of the heat exchange part can also be improved.

[0016] Furthermore, in the humidity control device of the present invention, preferably, in a plan view, a center line of the air inlet, a center line of the heat exchange section, and a center line of the humidifying section overlap.

[0017] According to the humidity control device of the present invention, the center line of the air inlet, the center line of the heat exchange part and the center line of the humidification part overlap, so the flowability of the airflow inside the humidity control device is further improved, the heat exchange capacity of the heat exchange component can be improved, thereby achieving energy saving, and on the other hand, the capacity of the humidification component can be improved, thereby improving the humidification efficiency. In other words, if the pressure loss is large on the airflow path, the heat loss after heat exchange is large, the humidity loss after humidification is large, and the overall performance of the machine is low.

[0018] In addition, in the humidity controlling device of the present invention, it is preferred that the heat exchange component includes a refrigerant piping connected to the heat exchange part, and a first cavity and a fourth cavity are formed in the shell, the first cavity is located between the air inlet and the heat exchange part, and is used to guide the airflow flowing in from the air inlet into the heat exchange part, the fourth cavity is adjacent to the first cavity and is separated from the first cavity, the refrigerant piping is at least partially arranged in the fourth cavity, and the ratio of the distance from the air inlet to the heat exchange part to the length of the heat exchange part is ≥0.3.

The fourth cavity is adjacent to the first cavity and is separated from the first cavity. The refrigerant piping is at least partially arranged in the fourth cavity. The ratio of the distance from the air inlet to the heat exchange part to the length of the heat exchange part is ≥0.3.

In addition, the distance from the air inlet to the heat exchange part is large enough to ensure that the airflow entering from the air inlet is evenly diffused in the length direction of the heat exchange part, thereby ensuring the overall heat exchange effect of the heat exchange part.

[0020] In addition, in the humidity control device of the present invention, a second cavity is preferably formed in the shell, and the second cavity is located between the humidifying part and the heat exchange part, and is used to guide the airflow after passing through the heat exchange part into the humidifying part, satisfying the following relationship: 65mm≤the distance from the heat exchange part to the humidifying part≤370mm.

The ratio of the distance between the humidifying part and the air outlet to the length of the humidifying part is ≥0.1. Therefore, it can prevent the formation of vortex at the air outlet due to the lack of air flow passing through the two sides of the heat exchange part, thereby hindering the fluidity of the air flow. In addition, the humidified air flow can be evenly and quickly delivered from the air outlet, thereby reducing the humidity loss in the machine and ensuring the comfort of the air flow delivered into the room.

And, as Figure 2 As shown, when viewed from above, the following relationships are satisfied: 0≤the distance between the center line L2 of the heat exchange section 21 and the center line L3 of the humidifying section 31≤65mm, 0≤the distance between the center line L1 of the air inlet JF and the center line L3 of the humidifying section 31≤65mm.

[0114] Here, if Figure 1 and Figure 3 As shown, the housing 10 is generally surrounded by a bottom wall 11, a top wall (not shown) and a side wall 12 to form a rectangular parallelepiped. The top wall is spaced apart from the bottom wall 11 in the Z direction. The side wall 12 connects the periphery of the bottom wall 11 with the periphery of the top wall, and includes: a first side wall 121 and a second side wall 122 spaced apart from each other in the X direction; and a third side wall 123 and a fourth side wall 124 spaced apart from each other in the Y direction, wherein the first side wall 121 is provided with, for example, a circular air inlet JF, and the second side wall 122 is provided with, for example, a circular air outlet CF.

[0115] In addition, if Figure 1 and Figure 3 As shown, the shell 10 is also provided with a first inspection port J1 and a second inspection port J2 which can be opened and closed by a cover plate, the first inspection port J1 is connected with the second inspection port J2, the first inspection port J1 is arranged at a position of the shell 10 adjacent to the following water inlet valve 35 of the humidifying component 30, and the area thereof is larger than the area of ​​the orthographic projection of the water inlet valve 35 on the plane where the first inspection port J1 is located, and the second inspection port J2 is arranged at a position of the shell 10 adjacent to at least a portion of the following water supply pipeline 33 of the humidifying component 30 (in the example shown in the figure, the first inspection port J1 and the second inspection port J2 are connected in an L shape, and the first inspection port J1 and the second inspection port J2 are arranged on the third side wall 123).

[0116] In addition, if Figures 1 to 3 As shown, a guide plate 70 is further provided in the shell 10, and the guide plate 70 is located between the first cavity Q1 and the fourth cavity Q4, and one end of the guide plate 70 is fixed to the side of the air inlet JF close to the fourth cavity Q4 (in the illustrated example, the Y1 direction side), and the other end of the guide plate 70 is fixed to the side of the heat exchange part 21 of the heat exchange assembly 20 close to the fourth cavity Q4 (in the illustrated example, the Y1 direction side).

[0117] In addition, if Figures 1 to 3As shown, hanging parts 80 are respectively provided at four corners of the housing 10 , and the humidity control device 100 can be installed by fixing the hanging parts 80 to a ceiling in the room, for example, using screws or the like.

[0118] (Structure of heat exchange components)

[0119] like Figure 1 and Figure 2 As shown, the heat exchange assembly 20 is a heat exchanger, including: a heat exchange portion 21; a refrigerant pipe 22 connected to the heat exchange portion 21; and a heat exchanger mounting plate. The heat exchange portion 21 is arranged on the airflow path, and the airflow flows through the heat exchange portion 21 for heat exchange and temperature adjustment. The heat exchanger mounting plate near the fourth cavity Q4 separates the heat exchange portion 21 and the fourth cavity Q4. The refrigerant pipe 22 near the fourth cavity Q4 is at least partially arranged in the fourth cavity Q4.

[0120] Here, if Figure 1 and Figure 2 As shown, the refrigerant pipe 22 includes a gas pipe 221 and a liquid pipe 222 , and both the gas pipe 221 and the liquid pipe 222 penetrate the side of the shell 10 close to the fourth cavity Q4 (the third side wall 123 in the example shown in the figure).

[0121] In addition, the heat exchange component 20 is connected to an outdoor unit (not shown) through the refrigerant pipe 22 to form a refrigerant circuit, which can heat the airflow when humidifying, and can also dehumidify the airflow by condensation when dehumidification is required instead of humidification.

[0122] In addition, it is preferred that the ratio of the distance from the air inlet JF to the heat exchange unit 21 to the length of the heat exchange unit 21 (the dimension in the Y direction in the illustrated example) is ≥ 0.3. This can prevent the increase in energy consumption of the heat exchange unit 21 due to the lack of airflow flowing through both sides of the heat exchange unit 21, and the distance from the air inlet JF to the heat exchange unit 21 is large enough to ensure that the airflow entering from the air inlet JF is evenly diffused in the length direction of the heat exchange unit 21, thereby ensuring the overall heat exchange effect of the heat exchange unit 21.

[0123] (Structure of humidification unit)

[0124] like Figure 1 and Figure 2 As shown, the humidifying assembly 30 includes a humidifying portion 31 , which is a wet film humidifier, and humidifies the air flowing through the wet film.

[0125] Here, if Figure 1 As shown, the humidifying unit 31 is disposed above the drain pan 50 .

[0126] In addition, if Figures 1 to 3As shown, the length of the humidifying section 31 (the dimension in the Y direction in the example shown) is greater than the length of the heat exchanging section 21 (the dimension in the Y direction in the example shown). Therefore, the humidifying capacity can be maximized while ensuring the heat exchanging capacity.

[0127] In addition, if Figures 1 to 3 As shown, the humidification assembly 30 further includes a water tank 32, a water supply pipeline 33 and a humidification pipeline 34. The water tank 32 is arranged on a side of the second cavity Q2 close to the fourth cavity Q4 (the Y1 direction side in the illustrated example) and is located above the drain pan 50. The water supply pipeline 33 is at least partially arranged in the fourth cavity Q4 and communicates with the humidification unit 31 via the humidification pipeline 34, for supplying water to the humidification unit 31. In addition, one side of the water tank 32 is communicated with the water supply pipeline 33, and the other side of the water tank 32 is communicated with the humidification unit 31 via the humidification pipeline 34. Therefore, the space on the side of the heat exchange unit 21 is used to store components such as the water tank 32, the water supply pipeline 33, the humidification pipeline 34 and the refrigerant pipe 22, which is conducive to miniaturization of the whole machine while reducing airflow obstruction.

[0128] In addition, if Figure 1 As shown, the humidifying assembly 30 has a water inlet JS, which is connected to the end of the water supply pipe 33 away from the water tank 32 and is opened on the side wall of the shell 10 close to the fourth cavity Q4 (the third side wall 123 in the illustrated example).

[0129] In addition, if Figures 1 to 3 As shown, the humidifying assembly 30 further includes a water inlet valve 35, and the water tank 32 is connected to the water inlet valve 35 via a water supply pipeline 33. The water inlet valve 35 and the water tank 32 are respectively arranged on both sides of the heat exchange portion 21 (in the example shown in the figure, on both sides in the X direction). In addition, a plurality of water inlet valves 35 are provided, and all are arranged in the housing 10, and the plurality of water inlet valves 35 are arranged in an up-and-down arrangement in the height direction of the housing 10.

[0130] In addition, it is preferred that the distance from the heat exchange section 21 to the humidifying section 31 is 65 mm ≤ 370 mm. In this way, it is possible to prevent the heat exchange area from being wasted due to the lack of airflow flowing through the two sides of the heat exchange section 21, resulting in low overall heat exchange performance, and to prevent the heat exchange section 21 from being too close to the humidifying section 31, resulting in the temperature of the heat exchange section 21 accelerating the aging and damage of the humidifying section 31. On the other hand, it is possible to prevent the airflow from generating eddies between the humidifying section 31 and the heat exchange section 21, thereby affecting the fluidity of the airflow. In addition, the airflow after heat exchange can be evenly diffused to the humidifying section 31, and the humidifying section 31 can be evenly humidified, thereby improving the overall performance. In addition, it is preferred that the ratio of the distance from the humidifying section 31 to the air outlet CF to the length of the humidifying section 31 (the dimension in the Y direction in the illustrated example) is ≥ 0.1. In this way, it can be prevented that there is no airflow flowing through the two sides of the heat exchange part 21, which would cause a vortex to form at the air outlet CF, thereby hindering the fluidity of the airflow. In addition, the humidified airflow can be delivered evenly and quickly from the air outlet CF, reducing the humidity loss in the machine and ensuring the comfort of the airflow delivered into the room.

[0131] like Figure 4 As shown, after the airflow enters the shell 10 from the air inlet JF, it is evenly diffused and flows through the heat exchange part 21. After being temperature-controlled by the heat exchange part 21, it is further evenly diffused and flows through the humidification part 31. After being humidified by the humidification part 31, it is sent out through the air outlet CF.

[0132] The velocity of the airflow near the air inlet JF and the air outlet CF is greater than the velocity of the airflow inside the shell 10. The airflow can not only be evenly diffused to the heat exchange part 21 and the humidification part 31 to ensure effective heat exchange area and humidification area, but also, since the airflow velocity inside the shell 10 is relatively low, the airflow can fully exchange heat and humidity with the heat exchange part 21 and the humidification part 31, further improving the heat exchange performance and humidification performance of the whole machine, thereby ensuring that the air finally delivered to the room meets the user's comfort requirements.

[0133] (Main Effects of the Present Embodiment)

[0134] According to the humidity control device 100 of this embodiment, when viewed from above, the following relationship is satisfied: 0≤the distance between the center line L2 of the heat exchange unit 21 and the center line L3 of the humidifying unit 31≤65mm, 0≤the distance between the center line L1 of the air inlet JF and the center line L3 of the humidifying unit 31≤65mm. Figure 4 As shown, it can ensure that the airflow flows smoothly in the airflow path, improve the fluidity of the airflow inside the humidity control device 100, reduce the pressure loss, and the deviation between the center line L1 of the air inlet JF and the center line L3 of the humidification section 31 is small, which can ensure that the airflow flows smoothly and evenly through the humidification section 31, ensure the humidification effect of the humidification section 31, and reduce the humidity loss inside the shell.

In addition, the electric heater may also be a heating plate, which may be one or more heating plates, evenly distributed in the airflow path in the length direction to heat the airflow passing through.

[0139] In addition, in the above embodiment, the heat exchange assembly 20 may also include a heat exchanger and an electric heater at the same time, using the electric heater to heat the humidified air and using the heat exchanger to dehumidify the air, or simply using the heat exchanger to adjust the air flow temperature. In this way, the humidity control device has various functions and flexible functional combinations.

[0140] In addition, in the above embodiment, a plurality of water inlet valves 35 are provided, and the plurality of water inlet valves 35 are arranged vertically in the height direction of the shell 10, but it is not limited thereto. The plurality of water inlet valves 35 may also be arranged horizontally, or only one water inlet valve 35 may be provided.

[0141] In addition, in the above embodiment, the number of wet film humidifiers as the humidifying section 31 may be one or two or more. In the case where there are two or more wet film humidifiers, the two or more wet film humidifiers are combined to form the humidifying section 31, and the center line L3 of the humidifying section 31 is the center line of the combined wet film humidifiers, and two adjacent wet films are sealed and connected.

[0142] Furthermore, in the above embodiment, the humidifying unit 31 is a wet film humidifier, but the present invention is not limited thereto. The humidifying unit 31 may also be a wet curtain, and water is sprayed on the wet curtain by a spray element to humidify the air passing through.

[0143] Furthermore, in the above-mentioned embodiment, the humidifying unit 31 is connected to the water tank 32 , but the present invention is not limited thereto, and the humidifying unit 31 may also be directly connected to municipal water.

[0144] Furthermore, in the above-mentioned embodiment, the humidity control device 100 may further include an air supply device in the housing 10 , or may use an external air supply device to supply air.

[0145] In addition, if Figure 5 As shown, the humidity control device 100 of the above embodiment can also be combined with an air conditioner 200, a fresh air device 300, a control unit (not shown), a branch air box 400, etc. to form a variety of air treatment systems.

[0146] For example, the following air treatment system can be formed, which includes a humidity control device 100, an air conditioner 200, a control unit and a detection unit (not shown). A heat exchanger is arranged in the humidity control device 100, and the heat exchanger and the outdoor unit 210 of the air conditioner 200 form a refrigerant circuit. The detection unit detects the temperature and humidity of the indoor air. The control unit adjusts the operating state of the humidity control device 100 according to the temperature and humidity detection results of the indoor air, performs humidification and dehumidification, and adjusts the humidification temperature, dehumidification temperature, and the set temperature of the indoor unit 220 of the air conditioner 200.

[0147] Alternatively, the following air treatment system can also be formed, which includes a humidity control device 100, a fresh air device 300, a control unit and a detection unit. The humidity control device 100 is arranged on the downstream side of the fresh air device 300. The humidity control device 100 can use the blower of the fresh air device 300 to supply air.

[0148] Alternatively, the following air treatment system can also be formed, which includes a humidity control device 100, a fresh air device 300, an air conditioner 200, a control unit and a detection unit. The humidity control device 100 is arranged on the downstream side of the fresh air device 300. The humidity control device 100 can use the blower of the fresh air device 300 to supply air (that is, the air supply path of the humidity control device 100 and the fresh air device 300 is common). The humidity control device 100 and the air conditioner 200 are connected through a refrigerant piping.

[0149] In addition, in the above-mentioned air treatment system, when the air supply paths of the humidity control device 100 and the fresh air device 300 are the same (the blower can be set in the fresh air device or on the air supply path), it is necessary to ensure that the air flow path inside the humidity control device 100 is smooth and minimize the pressure loss inside the machine.

[0150] In addition, in the above-mentioned air treatment system, the fresh air device 300 can be a fresh air blower, a total heat exchanger, a ventilation fan, etc. The fresh air device 300 can realize fresh air introduction, exhaust, internal circulation, ventilation and other modes.

[0151] In addition, the air treatment system may further include a purification unit (not shown, for purifying external air).

[0152] In addition, in the above-mentioned air treatment system, the detection unit can also detect the indoor and outdoor air quality. The detection unit can be set independently (integrated sensor) or at a suitable position on the air flow path (such as air inlet and air outlet).
