[0021] In order to make the purpose, technical scheme and advantages of the present application more clear, the embodiments of the present application will be described in detail below with reference to the drawings. It should be noted that the embodiments and features in the embodiments in the present application can be combined with each other arbitrarily without conflict.
[0022] The second ports in the present application are all outlets, and the first ports are all inlets.
[0023] The multi-connected machine provided by the embodiments of the present application is as follows: Figure 1As shown, the multi-split air conditioner comprises: a compressor 100; a dehumidification module comprising a first heat exchanger 210, a second heat exchanger 220 and a first throttling component 230, a second port of the compressor 100 being connected to a first port of the first heat exchanger 210, a second port of the first heat exchanger 210 being connected to a first port of the second heat exchanger 220 through the first throttling component 230, and a second port of the second heat exchanger 220 being connected to a first port of the compressor 100; a conversion heat exchange module comprising a third heat exchanger 310 and a second throttling component 320, the third heat exchanger 310 having a first flow channel and a second flow channel, and the second port of the first heat exchanger 210 being further connected to a first port of the first flow channel through the second throttling component 320, and a second port of the first flow channel being connected to the first port of the compressor 100; and a heat exchange medium heat exchange module having a heat exchange medium flow channel, the heat exchange medium flow channel being in circulation communication with the second flow channel.
[0024] A first refrigerant circulation flow path: the second port of the compressor 100 - the first heat exchanger 210 - the first throttling component 230 - the second heat exchanger 220 - the first port of the compressor 100.
[0025] A second refrigerant circulation flow path: the second port of the compressor 100 - the first heat exchanger 210 - the second throttling component 320 - the third heat exchanger 310 - the first port of the compressor 100.
[0026] The multi-split air conditioner has the dehumidification module for dehumidifying the indoor environment (and can also be used for drying clothes), the heat exchange medium in the circulation flow path formed by the heat exchange medium flow channel and the second flow channel, the conversion heat exchange module for realizing heat exchange between the refrigerant and the heat exchange medium, and the heat exchange medium heat exchange module for outputting cold energy through the heat exchange medium. The multi-split air conditioner has the functions of dehumidifying the indoor environment and outputting cold energy, and has better practicability.
[0027] The first throttling component 230 and the second throttling component 320 can be both electronic expansion valves, and the electronic expansion valves have a closed state and a flow rate adjusting state. The third heat exchanger 310 can be a plate heat exchanger.
[0028] In some embodiments, as shown, Figure 1 The heat exchange medium heat exchange module comprises: a refrigeration blanket module comprising a third flow channel of a refrigeration blanket 410, a second port of the second flow channel being connected to a first port of the third flow channel through a first pipeline 430, a second port of the third flow channel being connected to a first port of the second flow channel through a second pipeline 440, and the heat exchange medium flow channel comprising the third flow channel, the first pipeline 430 and the second pipeline 440.
[0029] When the second refrigerant circulation flow path is running, the refrigerant passing through the first flow path exchanges heat with the heat exchange medium passing through the second flow path through the third heat exchanger 310, absorbs the heat of the heat exchange medium, and cools the heat exchange medium, and the low-temperature heat exchange medium absorbs the heat of the cooling blanket 410 during passing through the third flow path, and cools the cooling blanket 410. The heat dissipation of the human body in different activity states: active state (slight activity): 180W; sleep state (static): 108W. The cooling blanket 410 is laid on the bed or in the tent, and is used when the human body is resting or sleeping. The output of the cooling capacity cools the human body, and the refrigeration capacity required in this process is small, which is more energy-saving.
[0030] In some embodiments, as shown in Figure 1 The first switch valve 420 can be arranged between the first pipeline 430 and the first port of the third flow path. When the cooling blanket sub-module is running, the first switch valve 420 is opened, and when the cooling blanket sub-module is stopped, the first switch valve 420 is closed. Alternatively, the first switch valve 420 can be arranged between the second port of the third flow path and the second pipeline 440. When the cooling blanket sub-module is running, the first switch valve 420 is opened, and when the cooling blanket sub-module is stopped, the first switch valve 420 is closed. The above can achieve the purpose of the present application, and the design idea is not deviated from the present application, which will not be repeated here, and should be within the protection scope of the present application.
[0031] In some embodiments, as shown in Figure 1 The heat exchange medium heat exchange module further comprises a cooling fan sub-module. The cooling fan sub-module comprises a first heat dissipation fan 450 and a fifth heat exchanger 460 arranged oppositely. The second port of the second flow path is connected to the first port of the fifth heat exchanger 460 through the first pipeline 430. The second port of the fifth heat exchanger 460 is connected to the first port of the second flow path through the second pipeline 440. The heat exchange medium flow path further comprises the fifth heat exchanger 460.
[0032] When the second refrigerant circulation flow path is running, the refrigerant passing through the first flow path exchanges heat with the heat exchange medium passing through the second flow path through the third heat exchanger 310, absorbs the heat of the heat exchange medium, and cools the heat exchange medium, and the low-temperature heat exchange medium absorbs the heat of the cooling blanket 410 during passing through the third flow path, and cools the cooling blanket 410. The heat dissipation of the human body in different activity states: active state (slight activity): 180W, the cooling fan sub-module is used to cool the indoor environment in the active state of the human body.
[0033] In some embodiments, as shown in Figure 1As shown, the cold fan sub-module further comprises a second switch valve 470. The second switch valve 470 can be arranged between the first pipeline 430 and the first port of the fifth heat exchanger 460, when the cold fan sub-module is started, the second switch valve 470 is opened, and the first cooling fan 450 is started; when the cold fan sub-module is stopped, the second switch valve 470 is closed, and the first cooling fan 450 is stopped; or the second switch valve 470 can be arranged between the second port of the fifth heat exchanger 460 and the second pipeline 440, when the cold fan sub-module is started, the second switch valve 470 is opened, and the first cooling fan 450 is started; when the cold fan sub-module is stopped, the second switch valve 470 is closed, and the first cooling fan 450 is stopped; the above can achieve the purpose of the application, and the design idea is not deviated from the design idea of the application, which will not be repeated here, and all should belong to the protection scope of the application.
[0034] In some embodiments, as shown in Figure 1 As shown, one of the first pipeline 430 and the second pipeline 440 is provided with a water tank 490 and a water pump 480, and the heat exchange medium is water. The cold fan sub-module cools the indoor environment by water cooling, which is more comfortable to use.
[0035] In some embodiments, as shown in Figure 1 As shown, the dehumidification module further comprises a first water collecting tray 240 and a second cooling fan 250, the first water collecting tray 240 is arranged below the second heat exchanger 220, and a drain port of the first water collecting tray 240 is connected to the water tank 490 through a third pipeline 494, so that condensed water generated when the first refrigerant circulation flow path is running flows into the water tank 490 to supplement the water tank 490; the cold fan sub-module further comprises a second water collecting tray 491, the second water collecting tray 491 is arranged below the fifth heat exchanger 460, and a drain port of the second water collecting tray 491 is connected to the water tank 490 through a fourth pipeline, so that condensed water generated when the cold fan sub-module is running flows into the water tank 490 to supplement the water tank 490; the water tank 490 is provided with a water level detection device 493, one of the first pipeline 430 and the second pipeline 440 is further provided with a three-way valve 492, the heat exchange medium flow channel further comprises an inlet of the three-way valve 492 and a first outlet of the three-way valve 492, and a second outlet of the three-way valve 492 is connected to a drain pipe 600;
[0036] When the water level detection device 493 is triggered, the water amount in the water tank 490 exceeds the preset water amount, at this time, the inlet of the three-way valve 492 is connected in communication with the second outlet of the three-way valve 492, the water pump 480 is operated, and the water tank 490 is drained to the outside through the drain pipe 600, so as to reduce the water amount in the water tank 490;
[0037] If the water level detection device 493 is not triggered, the water amount in the water tank 490 does not exceed the preset water amount, and at this time, the inlet of the three-way valve 492 is connected in communication with the first outlet of the three-way valve 492. When at least one of the air cooling fan sub-module and the cooling blanket sub-module is running, the water pump 480 is running.
[0038] In some examples, as shown in FIG. 1, the multi-split air conditioner further includes a refrigeration fresh-keeping function module, which includes a fourth heat exchanger 510 and a third throttling component 520. The second port of the first heat exchanger 210 is further connected to the first port of the fourth heat exchanger 510 through the third throttling component 520. The second port of the fourth heat exchanger 510 is connected to the first port of the compressor 100. Figure 1
[0039] The third refrigerant circulation flow path is: the second port of the compressor 100 - the first heat exchanger 210 - the third throttling component 520 - the fourth heat exchanger 510 - the first port of the compressor 100. The refrigeration fresh-keeping function module constitutes a refrigerator function module, which is used to meet the food refrigeration and fresh-keeping requirements of the refrigerator.
[0040] The third throttling component 520 can be an electronic expansion valve, which has a closed state and a flow rate adjustment state. When at least one of the first refrigerant circulation flow path, the second refrigerant circulation flow path, and the third refrigerant circulation flow path is running, the second heat dissipation fan 250 is running.
[0041] The multi-split air conditioner integrates the functions of dehumidification, drying, mobile air conditioner refrigeration, refrigerator, and cooling blanket refrigeration.

The fourth heat exchanger 510 is arranged to exchange heat with the refrigeration fresh-keeping chamber to meet the food refrigeration and fresh-keeping requirements (i.e., the refrigerator is integrated on the multi-split air conditioner). The heat exchange medium exchange module is located outside the main body. The first pipeline 430, the second pipeline 440, and the third pipeline 494 are all flexible hoses. The flexible hoses can be detachably installed.
[0043] The heat exchange medium heat exchange module is placed in the room, and since the first pipeline 430, the second pipeline 440 and the third pipeline 494 are all flexible pipes, the main body can be placed outdoors when the dehumidification module is not used, and the main body can be placed indoors when the dehumidification module is used (alternatively, the three flexible pipes are detached from the main body outdoors, the main body is placed indoors, and the three flexible pipes are mounted on the main body again). Moreover, the flexible pipes (water pipes) have a small diameter, and a large-diameter through hole does not need to be formed in the wall or the window (the existing mobile air conditioner needs to form two large-diameter through holes in the wall or the window to exchange heat between external air and a condenser of the mobile air conditioner).
[0044] To sum up, the technical scheme provided by the embodiment of the application, the dehumidification module is used to realize dehumidification of the indoor environment, the heat exchange medium flow channel and the second flow channel form a circulating flow path with the heat exchange medium, the conversion heat exchange module is used to realize heat exchange between the refrigerant and the heat exchange medium, and the heat exchange medium heat exchange module realizes output of cold energy through the heat exchange medium. The multi-split unit has the functions of dehumidification of the indoor environment and output of cold energy, and is better in practicability.
