(空调室外机的结构)(Structure of air conditioner outdoor unit)

如图7所示,空调室外机300具有压缩机310、四通阀320、室外热交换器330、调节阀340和储罐350。As shown in FIG. 7 , the air-conditioning outdoor unit 300 includes a compressor 310 , a four-way valve 320 , an outdoor heat exchanger 330 , a regulating valve 340 , and a storage tank 350 .

此处,如图1和图7所示,空调室外机300是三管式结构,除了像通常的两管式结构的空调室外机那样包括设有室外热交换器330和调节阀340的配管以及设有储罐350的配管外,还包括从压缩机310的排出管分岔出且设有四通阀360的分岔管。并且,空调室外机300通过作为制冷剂配管P的第一配管P1、第二配管P2和第三配管P3而与除湿装置100连接,其中,与除湿装置100的第一制冷剂配管端口D1连接的第一配管P1是供气体制冷剂流通的配管,与除湿装置100的第二制冷剂配管端口D2连接的第二配管P2是供液体制冷剂流通的配管,与除湿装置100的第三制冷剂配管端口D3连接的第三配管P3是高低压管(例如在第二热交换器150作为蒸发器起作用时供低压制冷剂流通)。并且,第三制冷剂配管端口D3的外径小于第一制冷剂配管端口D1的外径,但大于第二制冷剂配管端口D2的外径。Here, as shown in Fig. 1 and Fig. 7, the air conditioner outdoor unit 300 is a three-pipe structure, and in addition to the pipes provided with the outdoor heat exchanger 330 and the regulating valve 340 and the pipes provided with the storage tank 350 as in the conventional two-pipe structure air conditioner outdoor unit, it also includes a branch pipe branched from the discharge pipe of the compressor 310 and provided with a four-way valve 360. And the air conditioner outdoor unit 300 is connected to the dehumidifier 100 through the first pipe P1, the second pipe P2 and the third pipe P3 as the refrigerant pipe P, wherein the first pipe P1 connected to the first refrigerant pipe port D1 of the dehumidifier 100 is a pipe for circulating gas refrigerant, the second pipe P2 connected to the second refrigerant pipe port D2 of the dehumidifier 100 is a pipe for circulating liquid refrigerant, and the third pipe P3 connected to the third refrigerant pipe port D3 of the dehumidifier 100 is a high-low pressure pipe (for example, when the second heat exchanger 150 functions as an evaporator, a low-pressure refrigerant is circulated). Furthermore, the outer diameter of the third refrigerant pipe port D3 is smaller than the outer diameter of the first refrigerant pipe port D1 , but larger than the outer diameter of the second refrigerant pipe port D2 .

此外,如图7所示,在除湿运转时,经空调室外机300的压缩机310压缩后的高温高压制冷剂在由室外热交换器330冷却后经由第一配管P1流入除湿装置100的第一热交换器120,由此对流经除湿装置100的空气进行除湿,然后经由第二配管P2返回空调室外机300。另一方面,在除湿运转时,经空调室外机300的压缩机310压缩后的高温高压制冷剂也可经由第三配管P3流入除湿装置100的第二热交换器150,由此对流经除湿装置100的空气进行加热,然后由第二配管P2返回空调室外机300。In addition, as shown in FIG7 , during the dehumidification operation, the high-temperature and high-pressure refrigerant compressed by the compressor 310 of the air-conditioning outdoor unit 300 flows into the first heat exchanger 120 of the dehumidification device 100 through the first pipe P1 after being cooled by the outdoor heat exchanger 330, thereby dehumidifying the air flowing through the dehumidification device 100, and then returns to the air-conditioning outdoor unit 300 through the second pipe P2. On the other hand, during the dehumidification operation, the high-temperature and high-pressure refrigerant compressed by the compressor 310 of the air-conditioning outdoor unit 300 may also flow into the second heat exchanger 150 of the dehumidification device 100 through the third pipe P3, thereby heating the air flowing through the dehumidification device 100, and then returns to the air-conditioning outdoor unit 300 through the second pipe P2.

(本实施方式的主要效果)(Main Effects of the Present Embodiment)

根据本实施方式的空气处理系统1,在除湿装置中,将第一热交换器的额定除湿能力设为D,将换气装置的额定风量设为W,将第一热交换器的有效长度设为L时,满足0.1米*W/D<L<0.37米*W/D的关系,其中,D的单位是升/小时,W的单位是米3/分钟,L的单位是米,因此,在沿用空调用的热交换器作为第一热交换器时,有助于在抑制送风压力损失的同时,快速确定除湿用的热交换器的有效长度。此外,当L小于作为下限的0.1米*W/D时,除湿能力不足;当L大于作为上限的0.37米*W/D时,能获得充分的性能(除湿能力),但会造成能力过强而难以控制、成本变高、产品尺寸大型化。According to the air treatment system 1 of the present embodiment, in the dehumidification device, when the rated dehumidification capacity of the first heat exchanger is set to D, the rated air volume of the ventilation device is set to W, and the effective length of the first heat exchanger is set to L, the relationship of 0.1m*W/D<L<0.37m*W/D is satisfied, wherein the unit of D is liter/hour, the unit of W is m3 /minute, and the unit of L is meter. Therefore, when the heat exchanger used for air conditioning is used as the first heat exchanger, it is helpful to quickly determine the effective length of the heat exchanger for dehumidification while suppressing the air supply pressure loss. In addition, when L is less than 0.1m*W/D as the lower limit, the dehumidification capacity is insufficient; when L is greater than 0.37m*W/D as the upper limit, sufficient performance (dehumidification capacity) can be obtained, but it will cause the capacity to be too strong and difficult to control, the cost to increase, and the product size to be large.

上面结合附图对本实用新型进行了示例性描述,显然本实用新型的具体实现并不受上述实施方式的限制。The present invention is described above by way of example in conjunction with the accompanying drawings. It is obvious that the specific implementation of the present invention is not limited to the above-mentioned embodiments.

例如,在上述实施方式中,还可包括经由第一配管P1、第二配管P2而与空调室外机300连接的空调室内机。For example, in the above-described embodiment, an air-conditioning indoor unit connected to the air-conditioning outdoor unit 300 via the first pipe P1 and the second pipe P2 may be further included.

此外,在上述实施方式中,第三配管P3是高低压管,但并不局限于此,如图8所示,第三配管P3也可以是与压缩机310的排出管导通且仅供高压气体制冷剂流通的配管,使第二热交换器150仅作为冷凝器起作用,由此形成简单的制冷剂回路。在这种情况下,供第三配管P3连接的第三制冷剂配管端口D3的外径既可以形成为小于第一制冷剂配管端口D1的外径且大于第二制冷剂配管端口D2的外径,也可以形成为与第一制冷剂配管端口D1的外径相同。In addition, in the above embodiment, the third pipe P3 is a high-low pressure pipe, but it is not limited to this. As shown in FIG8 , the third pipe P3 may also be a pipe that is connected to the discharge pipe of the compressor 310 and only allows the high-pressure gas refrigerant to flow, so that the second heat exchanger 150 functions only as a condenser, thereby forming a simple refrigerant circuit. In this case, the outer diameter of the third refrigerant pipe port D3 connected to the third pipe P3 may be formed to be smaller than the outer diameter of the first refrigerant pipe port D1 and larger than the outer diameter of the second refrigerant pipe port D2, or may be formed to be the same as the outer diameter of the first refrigerant pipe port D1.

此外,在上述实施方式中,制冷剂回路的结构不局限于图7、图8所示的结构,只要是能实现除湿装置100中的一个热交换器作为蒸发器、另一个热交换器作为冷凝器的制冷剂回路都可以。In addition, in the above-mentioned embodiment, the structure of the refrigerant circuit is not limited to the structure shown in Figures 7 and 8, and any refrigerant circuit can be used as long as one heat exchanger in the dehumidification device 100 is used as an evaporator and the other heat exchanger is used as a condenser.

此外,在上述实施方式中,第一热交换器120和第二热交换器150经由制冷剂配管与一台空调室外机300连接,但并不局限于此,也可以是第一热交换器120经由制冷剂配管与一台空调室外机连接,第二热交换器150经由制冷剂配管与另一台空调室外机连接。In addition, in the above-mentioned embodiment, the first heat exchanger 120 and the second heat exchanger 150 are connected to an air-conditioning outdoor unit 300 via a refrigerant piping, but it is not limited to this. The first heat exchanger 120 can also be connected to an air-conditioning outdoor unit via a refrigerant piping, and the second heat exchanger 150 can be connected to another air-conditioning outdoor unit via a refrigerant piping.

此外,在上述实施方式中,在壳体110内设置有利用制冷剂进行热交换的第二热交换器150,但并不局限于此,也可设置位于第一热交换器120下游的加热器(例如PTC加热器)来代替第二热交换器150,或者直接省略第二热交换器150。此时,可追加在换气装置200处于非送风状态时断电以使加热器停止加热的流量检测器。In addition, in the above embodiment, the second heat exchanger 150 for heat exchange using refrigerant is provided in the housing 110, but the present invention is not limited thereto, and a heater (such as a PTC heater) located downstream of the first heat exchanger 120 may be provided to replace the second heat exchanger 150, or the second heat exchanger 150 may be directly omitted. In this case, a flow detector may be added to cut off the power when the ventilation device 200 is in a non-air supply state so that the heater stops heating.

此外,在上述实施方式中,在省略第二热交换器150时,可同时省略第三制冷剂配管端口D3、调节阀142和第三配管P3,即此时可采用两管式结构的空调室外机300。Furthermore, in the above embodiment, when the second heat exchanger 150 is omitted, the third refrigerant pipe port D3, the regulating valve 142 and the third pipe P3 may be omitted at the same time, that is, a two-pipe structure of the air conditioner outdoor unit 300 may be adopted.

此外,在上述实施方式中,换气装置200具有全热交换器240,但并不局限于此,也可省略全热交换器240。Furthermore, in the above-described embodiment, the ventilator 200 includes the total heat exchanger 240 , but the present invention is not limited thereto, and the total heat exchanger 240 may be omitted.

应当理解,本实用新型在其范围内,能将实施方式中的各个部分自由组合,或是将实施方式中的各个部分适当变形、省略。It should be understood that within the scope of the present invention, various parts in the embodiments can be freely combined, or various parts in the embodiments can be appropriately deformed or omitted.
