1-4, an embodiment of the present disclosure provides a multi-split system, including an air conditioning unit, a floor heating unit, and a potable water unit. The air conditioning unit comprises an outdoor heat exchanger 100 and at least one indoor heat exchanger 110, and the outdoor heat exchanger 100 and the indoor heat exchanger 110 form a first circulation loop; the floor heating unit comprises a plurality of heating devices 200, and the plurality of heating devices 200 form a second circulation loop; wherein the circulation medium of the second circulation loop is water, and the second circulation loop exchanges heat with the outdoor heat exchanger 100 to heat the water in the second circulation loop; the drinking water unit includes a purification device 300 and a water outlet device 310; the purifying device 300 is communicated with the second circulation loop, the water outlet device 310 is communicated with the purifying device 300, and water in the second circulation loop flows out of the water outlet device 310 after being filtered by the purifying device 300, so that the water is drunk by a user.

In this embodiment, the air conditioning unit performs cooling and heating functions, and the circulation medium of the first circulation circuit is a refrigerant. The air conditioning unit includes a compressor, an outdoor heat exchanger 100, a throttle device, and a plurality of indoor heat exchangers 110, wherein the plurality of indoor heat exchangers 110 are connected in parallel. When the air conditioning unit is used for refrigerating, the compressor compresses the refrigerant into high-temperature and high-pressure refrigerant and flows to the outdoor heat exchanger 100, the refrigerant of the outdoor heat exchanger 100 flows to the throttling device after heat exchange, the refrigerant with low temperature and low pressure flows to the indoor heat exchanger 110 after the throttling pressure reduction effect of the throttling device, and the refrigerant of the indoor heat exchanger 110 flows back to the compressor for recompression after heat exchange.

The circulation medium in the second circulation loop is water, and the second circulation loop is capable of exchanging heat with the outdoor heat exchanger 100, so that the water in the second circulation loop is heated by the heat of the outdoor heat exchanger 100. The heated high-temperature water flows into the plurality of heating apparatuses 200, thereby increasing the temperature of the room in which the heating apparatuses 200 are disposed. Thus, the floor heating unit realizes the heating function.

On the basis of an air conditioning unit and a floor heating unit, the multi-split system provided by the embodiment of the disclosure is further provided with a drinking water unit. The drinking water unit includes a purification device 300 and a water outlet device 310, and water in the second circulation loop flows out of the water outlet device 310 after being filtered by the purification device 300, thereby providing drinking hot water to a user. That is, the hot water of the second circulation circuit is filtered to become hot water that can be referred to by the user.

It can be seen that the multi-split system provided by the embodiment of the disclosure can realize the functions of heating/refrigerating, heating and drinking hot water.

Optionally, the purification device comprises a multi-layer water filter. The multi-layer water filter is adopted to realize better filtering effect.

Optionally, the second circulation loop includes a heat exchange section 210, a water inlet section 220, a heat supply section, and a water outlet section 230. The plurality of heat supply devices 200 are arranged in parallel to form a heat supply section, a first end of the heat supply section is communicated with a first end of the water inlet section 220, a second end of the heat supply section is communicated with a second end of the water outlet section 230, a first end of the heat exchange section 210 is communicated with the first end of the water outlet section 230, and a second end of the heat exchange section 210 is communicated with the second end of the water inlet section 220. Also, a heat exchange section 210 is located within the outdoor heat exchanger 100 for exchanging heat with the outdoor heat exchanger 100, i.e., heating the circulating medium at the heat exchange section 210. The flow direction of the heated water in the heat exchange section 210 is sequentially a water inlet section 220, a heat supply section and a water outlet section 230, and finally flows back to the heat exchange section 210 for reheating. And the water temperature in the second circulation loop is ensured by circulating and reciprocating in this way.

Optionally, the heating device 200 includes a radiator, water distributors are disposed at water inlet ends of the plurality of radiators, and water collectors are disposed at water outlet ends of the plurality of radiators. The water in the water inlet section 220 flows to the plurality of radiators through the water separator, respectively, and the water having a reduced temperature after heat dissipation in the plurality of radiators is collected in the water collector and then flows to the water outlet section 230. Finally, the water in the water outlet section 230 is reheated toward the heat exchange section 210.

Optionally, the heat exchange section 210 is disposed against heat exchange tubes of the outdoor heat exchanger 100.

In this embodiment, when the high-temperature refrigerant circulates in the heat exchange tube of the outdoor heat exchanger 100, heat is transferred to the heat exchange section 210 through the tube wall of the heat exchange tube, and the circulating medium in the heat exchange section 210 is heated. The heated water in the heat exchange section 210 then continues to flow to the heat supply section to supply heat to the indoor space.

Optionally, a water pump 240 is provided on the second circulation loop.

In the present embodiment, the circulation medium in the second circulation circuit is driven to circulate by the water pump 240. The water pump 240 is disposed at the water inlet section 220, or the water pump 240 is disposed at the water outlet section 230. When the water pump 240 is started, the heated water in the heat exchange section 210 flows to the water inlet section 220, the heated water in the water inlet section 220 flows to the heat supply section, and the heated water in the heat supply section flows to the water outlet section 230 after being heated, so that circulation of a circulating medium is realized.

Optionally, a third flow regulator is disposed on the second circulation loop.

In the embodiment, the water flow in the second circulation loop is regulated by the third flow regulator, so that the use efficiency of the floor heating unit can be improved.

Illustratively, the temperature of the room in which the heating device 200 is disposed is low, and rapid temperature rise is required in the room. At this time, the opening degree of the third flow regulator is maximum, water in the second circulation loop circulates rapidly, and the water flow rate at the heat exchange section 210 increases to perform rapid heat exchange. In this way, the heat dissipation efficiency of the hot water in the heat exchange section 210 is higher after flowing to the heating apparatus 200 through the water inlet section 220, thereby rapidly increasing the temperature in the room.

Still another example, the temperature of the room in which the heating device 200 is disposed is high, and the room does not need to be continuously warmed. At this time, the opening degree of the third flow regulator is reduced, and the water flow rate at the heat exchange section 210 is reduced, so that the heat exchange rate is reduced. In this way, the circulation speed of the water in the second circulation loop is reduced while maintaining the temperature in the room, thereby improving the use efficiency of the floor heating unit.

Alternatively, as shown in fig. 1, the purifying device 300 is communicated with the water outlet sides of the plurality of heating devices 200 through the first branch 330.

In the present embodiment, the water outlet side of the plurality of heating apparatuses 200 is the water outlet section 230, that is, the purifying apparatus 300 is communicated with the water outlet section 230 through the first branch 330. The heated water in the heat exchange section 210 flows to the water inlet section 220, the heated water in the water inlet section 220 flows to the heat supply section, and the water in the heat supply section flows to the water outlet section 230 after being used for heat supply. The water in the water outlet section 230 has two flow paths, one of which flows to the heat exchange section 210 for reheating and the other of which flows to the purification apparatus 300 through the first branch 330. After the water flowing to the purification apparatus 300 is filtered, it flows out of the water outlet apparatus 310, thereby providing drinking water to the user. Since the first branch 330 is connected to the water outlet section 230, the temperature of the water flowing out through the first branch 330 is not very high.

Optionally, a first flow regulator 331 is disposed on the first branch 330.

In this embodiment, the water flow on the first branch 330 is regulated by a first flow regulator 331. When the user has a large water demand, the opening degree of the first flow regulator 331 is maximized so as to satisfy the user's water demand. When the water demand of the user is smaller, the opening degree of the first flow regulator 331 is reduced, so that the water demand of the user can be met, and the reduction of the heating effect caused by excessive outflow of the circulating medium in the second circulating loop can be avoided.

Alternatively, as shown in fig. 2, the purification apparatus 300 is communicated with the water inlet side of the plurality of heating apparatuses 200 through the second branch 340.

In the present embodiment, the water inlet side of the plurality of heating apparatuses 200 is the water inlet section 220, that is, the purifying apparatus 300 is communicated with the water inlet section 220 through the second branch 340. The water heated in the heat exchange section 210 flows to the water inlet section 220, and the water in the water inlet section 220 has two flow paths, one of which flows to the heat supply section and the other of which flows to the purification apparatus 300 through the second branch 340. Wherein the water flowing to the heat supply section heats, and then the water continues to flow to the water outlet section 230, and finally flows from the water outlet section 230 to the heat exchange section 210 for reheating. After the water flowing to the purification apparatus 300 is filtered, it flows out of the water outlet apparatus 310, thereby providing drinking water to the user. Since the second branch 340 is communicated with the water inlet section 220, the temperature of the water flowing out through the second branch 340 is relatively high.

Optionally, a second flow regulator 341 is disposed on the second branch 340.

In this embodiment, the water flow on the second leg 340 is regulated by a second flow regulator 341. When the user has a large water demand, the opening degree of the second flow regulator 341 is maximized so as to satisfy the user's water demand. When the water demand of the user is smaller, the opening degree of the second flow regulator 341 is reduced, so that the water demand of the user can be met, and the reduction of the heating effect caused by excessive outflow of the circulating medium in the second circulating loop can be avoided.

Alternatively, as shown in fig. 3, the purifying device 300 is connected to the water outlet side of the plurality of heat supply devices 200 through the first branch 330, and is connected to the water inlet side of the plurality of heat supply devices 200 through the second branch 340. The first branch 330 is provided with a first flow regulator 331, and the second branch 340 is provided with a second flow regulator 341.

In the present embodiment, the first branch 330 flows out hot water with a lower temperature, and the second branch 340 flows out hot water with a higher temperature. The water heated in the heat exchange section 210 flows to the water inlet section 220, and the water in the water inlet section 220 has two flow paths, one of which flows to the heat supply section and the other of which flows to the purification apparatus 300 through the second branch 340. Wherein the water flowing to the heat supply section heats and then the portion of the water continues to flow to the water outlet section 230. The water in the water outlet section 230 has two flow paths, one of which flows to the heat exchange section 210 for reheating and the other of which flows to the purification apparatus 300 through the first branch 330. Thus, the purifying device 300 is respectively communicated with the second circulation loop through the first branch 330 and the second branch 340, and is regulated through the first flow regulator 331 and the second flow regulator 341, so that the requirements of users on different temperatures of the drinking water can be met.

Illustratively, the user needs higher temperature potable water, at which time the second flow regulator 341 is turned on and the first flow regulator 331 is turned off, and only the higher temperature water in the water inlet section 220 flows to the purification apparatus 300 through the second branch 340. And then flows out of the water outlet device 310 for the user to drink after being filtered by the purifying device 300.

Still another example is when the user needs cooler drinking water, at which time the first flow regulator 331 is turned on and the second flow regulator 341 is turned off, and only the cooler water in the water outlet section 230 flows to the purifying device 300 through the first branch 330. And then flows out of the water outlet device 310 for the user to drink after being filtered by the purifying device 300.

Still another example, the user needs moderately warm drinking water, at which time the first flow valve opening is adjusted to half-open and the second flow valve opening is adjusted to half-open. Thus, water having a higher temperature and water having a lower temperature simultaneously flows to the purification apparatus 300. And then flows out of the water outlet device 310 for the user to drink after being filtered by the purifying device 300.

Optionally, as shown in fig. 4, the potable water unit further comprises a heating device 320. The heating device 320 is used to heat the water filtered by the purifying device 300.

In the present embodiment, in the case where the purification apparatus 300 is connected to the water outlet side of the plurality of heating apparatuses 200 through the first branch 330, the first branch 330 flows hot water having a relatively low temperature into the purification apparatus 300. If the temperature of the hot water at this time cannot meet the user's demand, the heating device 320 is activated, and the hot water is further heated by the heating device 320. When the hot water is heated to a desired temperature, it is discharged through the water outlet device 310 for the user to drink.

Optionally, the heating device 320 comprises an electric heater. The electric heater can heat water temperature when being electrified.

Optionally, a water supplementing pipeline is arranged on the second circulation loop, and circulation medium is supplemented to the second circulation loop through the water supplementing pipeline.

In this embodiment, since the drinking water unit of the multi-split air conditioning system directly filters the water in the second circulation loop for the user to drink, the water amount in the second circulation loop is gradually reduced, and if the water amount is too small, the heat supply function of the floor heating unit is affected. And a water quantity monitor is arranged on the second circulation loop, and when the water quantity monitor detects that the water quantity of the second circulation loop is smaller than the preset water quantity, a water source is supplemented to the second circulation loop through a water supplementing pipeline. In this way, it is possible to continuously heat and continuously supply potable hot water to the user.

Optionally, a first temperature sensor is disposed at the water outlet device 310, where the first temperature sensor is used for detecting the water outlet temperature; the water inlet section 220 is provided with a second temperature sensor, and the first temperature sensor is used for detecting the water temperature of the water inlet section 220; the water outlet section 230 is provided with a third temperature sensor for detecting the water temperature of the water outlet section 230. The first temperature sensor, the second temperature sensor and the third temperature sensor are all electrically connected to the control unit of the multi-split system, and the corresponding detected temperatures are transmitted to the control unit.

In this embodiment, when the purification apparatus 300 is respectively connected to the second circulation circuit through the first branch 330 and the second branch 340, the first branch 330 is provided with the first flow regulator 331, and the second branch 340 is provided with the second flow regulator 341. The first branch 330 flows hot water with a lower temperature to the filter device and the second branch 340 flows hot water with a higher temperature to the filter device. The control logic of the first flow regulator 331, the second flow regulator 341 and the heating apparatus 320 is as follows:

a user inputs a water temperature requirement to a control unit of the multi-split system, and the control unit acquires water temperatures of the water inlet section 220 and the water outlet section 230;

in the case that the water temperatures of the water inlet section 220 and the water outlet section 230 meet the water temperature requirement, the first flow regulator 331 is controlled to be opened and the second flow regulator 341 is controlled to be closed, that is, water is preferentially supplied to the water outlet device 310 through the first branch 330;

in case that only the water temperature of the water inlet section 220 satisfies the water temperature requirement, the second flow regulator 341 is controlled to be opened and the first flow regulator 331 is controlled to be closed, i.e., water is supplied to the water outlet device 310 only through the second branch 340 at this time.

In case that the water temperatures of both the water inlet section 220 and the water outlet section 230 do not meet the water temperature requirement, the first flow regulator 331 is controlled to be turned off and the second flow regulator 341 is controlled to be turned on, and the heating device 320 is controlled to be turned on. I.e. the water is now supplied to the water outlet means 310 via the second branch 340 and the water temperature is further heated by the heating means 320 to meet the water temperature demand.
