Energy expenditures and greenhouse gas emissions related to building operations account for about one-third of the total social amount. Heating and air-conditioning energy consumption, which is directly related to people's well-being, is the most important component. With the improvement of building functions and the improvement of people's demand for comfort, the proportion of energy consumption has increased year by year. Therefore, improving the energy efficiency of air-conditioning systems is an important way to reduce the total energy consumption of society and achieve energy conservation and emission reduction.

[0003] The air conditioning system disclosed in the related art generally uses air supply terminals or radiation terminals to heat the room. For example, the southern region mostly uses air supply terminals for heating to meet the user's demand for rapid heating; the northern region mostly uses radiation terminals for heating to meet the user's demand for heating comfort. In addition, in order to solve the problem of frosting of the air conditioning system during heating, hot air bypass defrosting or reverse cycle defrosting is generally used.

[0055] The multifunctional water-fluorine interconnected machine provided in the embodiment of the present disclosure adopts a system to realize multiple functional modes by controlling the status of the circulating water pump 5 and multiple valves, and then satisfies the needs of rapid heating and heating comfort, as well as the needs of uninterrupted heating during defrosting by selecting and switching appropriate operating modes.

[0056] Alternatively, if Figure 1 As shown, the circulating water pump 5 is arranged on the second circulation loop 300 between the second medium channel 102 and the bypass branch of the indoor heat exchanger 4. The second valve 3.1 is arranged on the inflow side of the second medium channel 102 of the outdoor heat exchanger 3, the third valve 4.1 is arranged on the inflow side of the second medium channel 102 of the indoor heat exchanger 4, and the fifth valve 7.1 is arranged on the outflow side of the heat exchange device 7. The circulating water pump 5 is located on the downstream side of the first valve 6.1 to the fifth valve 7.1, and the bypass branch is located between the second medium channel 102 of the indoor heat exchanger 4 and the heat exchange device 7.

[0057] Optionally, the circulating medium in the first circulation loop 200 includes a refrigerant. In the multifunctional water-fluorine interconnected machine provided in the embodiment of the present disclosure, a compressor 1, a four-way reversing valve 2 and an expansion valve 4.3 are also provided in the first circulation loop 200. The compressor 1 is used to drive the flow of the refrigerant in the first circulation loop 200, the four-way reversing valve 2 is used to switch the flow direction of the refrigerant in the first circulation loop 200 so as to realize the first circulation loop 200 to run a heating cycle or a refrigeration cycle, and the expansion valve 4.3 is used to throttle and reduce the pressure of the refrigerant flowing through. Among them, when the first circulation loop 200 runs a heating cycle, the flow direction of its refrigerant is the compressor 1, the four-way reversing valve 2, the indoor heat exchanger 4, the outdoor heat exchanger 3 and the compressor 1. When the first circulation loop 200 runs a refrigeration cycle, the flow direction of its refrigerant is the compressor 1, the four-way reversing valve 2, the outdoor heat exchanger 3, the indoor heat exchanger 4 and the compressor 1.

[0058] Optionally, the circulating medium in the second circulation loop 300 includes water or antifreeze. Water and antifreeze have excellent cooling capacity, and the source detection device 6 inputs cold / heat into the second circulation loop 300 through the circulating water or antifreeze.

[0059] Optionally, the source detection device 6 includes a heat storage device and / or a cold storage device. The heat storage device is used to store heat and input heat to the second circulation loop 300; the cold storage device is used to store cold energy and input cold energy to the second circulation loop 300.

[0060] Exemplarily, the heat storage device includes a heat energy collection device for a city heating network, a geothermal energy collection device, an underground hot water heat energy collection device, a solar thermal collector, a building waste heat collection device, or an industrial waste heat collection device. The cold storage device includes an indirect evaporative cooling device or a cooling tower. Here, the types of the heat storage device and the cold storage device can be one or more. For example, the source measurement device 6 includes a heat storage device and a cold storage device, the heat storage device includes a heat energy collection device for a city heating network and a geothermal energy collection device, and the cold storage device includes a cooling tower. According to the requirements of the operating mode of the multifunctional water-fluorine interconnection machine, heat or cold is input into the second circulation loop 300.

[0062] For example, the multifunctional water-fluorine interconnection machine is applied to multiple rooms, and each room corresponds to an indoor heat exchanger 4 and a heat exchange device 7. The heat exchange devices 7 of each room can be the same or different. For example, room 1 uses a ceiling heat radiator, room 2 uses a wall heat radiator, and room 3 uses a wall heat radiator.

[0063] Alternatively, if Figure 2As shown, the third medium channel of the outdoor heat exchanger 3 is the first air channel 103, and the air is made to flow through the first air channel 103 by the outdoor fan 3.2 to exchange heat with the first medium channel 101 of the outdoor heat exchanger 3 and / or the second medium channel 102 of the outdoor heat exchanger 3; the third medium channel of the indoor heat exchanger 4 is the second air channel 104, and the air is made to flow through the second air channel 104 by the indoor fan 4.2 to exchange heat with the first medium channel 101 of the indoor heat exchanger 4 and / or the second medium channel 102 of the indoor heat exchanger 4.

[0064] In this embodiment, when the outdoor fan 3.2 is started, the outdoor air flows through the first air channel 103, thereby exchanging heat with the first medium channel 101 and / or the second medium channel 102 of the outdoor heat exchanger 3. When the indoor fan 4.2 is started, the indoor air flows through the second air channel 104, thereby exchanging heat with the first medium channel 101 and / or the second medium channel 102 of the indoor heat exchanger 4.

[0065] Alternatively, if Figure 3 As shown, the multifunctional water-fluorine interconnection machine has a water source working mode. The water source working mode corresponds to the first circulation loop 200 running a refrigeration cycle or a heating cycle, the circulating water pump 5 is turned on, the first valve 6.1, the second valve 3.1 and the fourth valve 5.1 are turned on, and the third valve 4.1 and the fifth valve 7.1 are closed.

[0066] In this embodiment, the outdoor fan 3.2 is turned off and the indoor fan 4.2 is turned on. The circulation direction of the second circulation loop 300 is the source detection device 6, the second medium channel 102 and the bypass branch of the outdoor heat exchanger 3, the circulating water pump 5, and the source detection device 6. In addition, when the cold / heat of the source detection device 6 passes through the second medium channel 102 of the outdoor heat exchanger 3, it exchanges heat with the first medium channel 101 of the outdoor heat exchanger 3 to ensure the operation of the outdoor heat exchanger 3, thereby realizing the water source working mode.

[0067] Exemplarily, the first circulation loop 200 runs a refrigeration cycle, the first valve 6.1 corresponding to the cold storage device is opened, and the cold storage device inputs cold energy to the second circulation loop 300 through water or antifreeze. When the water or antifreeze flows through the second medium channel 102 of the outdoor heat exchanger 3, it exchanges heat with the high-temperature refrigerant in the first medium channel 101 of the outdoor heat exchanger 3 to maintain the operation of the outdoor heat exchanger 3.

[0068] In another exemplary embodiment, the first circulation loop 200 runs a heating cycle, the first valve 6.1 corresponding to the heat storage device is opened, and the heat storage device inputs heat to the second circulation loop 300 through water or antifreeze. When the water or antifreeze flows through the second medium channel 102 of the outdoor heat exchanger 3, it exchanges heat with the low-temperature refrigerant in the first medium channel 101 of the outdoor heat exchanger 3 to maintain the operation of the outdoor heat exchanger 3.

[0069] Alternatively, if Figure 4 As shown, the multifunctional water-fluorine interconnection machine has a direct cooling / heating mode 1 using external energy. The direct cooling / heating mode 1 using external energy corresponds to the first circulation loop 200 being blocked, the source measuring device 6 outputting cooling or heat, the circulating water pump 5 being turned on, the first valve 6.1, the third valve 4.1 and the fourth valve 5.1 being turned on, and the second valve 3.1 and the fifth valve 7.1 being turned off.

[0070] In this embodiment, the first circulation loop 200 is blocked, and only the second circulation loop 300 is used to supply cooling or heating to the room. The outdoor fan 3.2 is turned off, and the indoor fan 4.2 is turned on. The circulation flow direction of the second circulation loop 300 is the source detection device 6, the second medium channel 102 of the indoor heat exchanger 4 and the bypass branch, the circulating water pump 5, and the source detection device 6. In addition, the cold / heat of the source detection device 6 cools or heats the room when passing through the second medium channel 102 of the indoor heat exchanger 4.

[0071] Exemplarily, the first valve 6.1 corresponding to the cold storage device is opened, and the cold storage device inputs cold energy into the second circulation loop 300 through water or antifreeze. When the water or antifreeze flows through the second medium channel 102 of the indoor heat exchanger 4, under the action of the indoor fan 4.2, the indoor air flows through the second air channel 104 and exchanges heat with the second medium channel 102 of the indoor heat exchanger 4 to form cold air to supply cold air indoors.

[0072] In another exemplary embodiment, the first valve 6.1 corresponding to the heat storage device is opened, and the heat storage device inputs heat to the second circulation loop 300 through water or antifreeze. When the water or antifreeze flows through the second medium channel 102 of the indoor heat exchanger 4, under the action of the indoor fan 4.2, the indoor air flows through the second air channel 104 and exchanges heat with the second medium channel 102 of the indoor heat exchanger 4 to form hot air to supply heat to the room.

[0073] Alternatively, if Figure 5 As shown, the multifunctional water-fluorine interconnection machine has a direct cooling / heating mode 2 using external energy. The direct cooling / heating mode 2 using external energy corresponds to the first circulation loop 200 being blocked, the source detection device 6 outputting heat, the circulating water pump 5 being turned on, the first valve 6.1 and the fifth valve 7.1 being turned on, and the second valve 3.1, the third valve 4.1 and the fourth valve 5.1 being turned off.

[0074] In this embodiment, the first circulation loop 200 is blocked, and heat is supplied to the room only through the second circulation loop 300. The outdoor fan 3.2 is turned off, and the indoor fan 4.2 is turned off. The circulation flow direction of the second circulation loop 300 is the source detection device 6, the heat exchange device 7, the circulating water pump 5, and the source detection device 6. The first valve 6.1 corresponding to the heat storage device is opened, and the heat storage device inputs heat to the second circulation loop 300 through water or antifreeze. The heat of the source detection device 6 supplies heat to the room when passing through the heat exchange device 7. The heat exchange device 7 provides high heating comfort.

[0075] Alternatively, if Figure 6 As shown, the multifunctional water-fluorine interconnection machine has a first heating and defrosting mode. The first heating and defrosting mode corresponds to the first circulation loop 200 being blocked, the circulating water pump 5 being turned on, the second valve 3.1 and the fourth valve 5.1 being turned on, and the first valve 6.1, the third valve 4.1 and the fifth valve 7.1 being turned off.

[0076] In the disclosed embodiment, the first circulation loop 200 is blocked, and defrosting is performed through the second circulation loop 300. The outdoor fan 3.2 is turned off, and the indoor fan 4.2 is turned off. After the circulating water pump 5 is turned on, the water or antifreeze in the second circulation loop 300 begins to circulate, and when it flows through the second medium channel 102 of the outdoor heat exchanger 3, it exchanges heat with the first medium channel 101 of the outdoor heat exchanger 3, thereby performing defrosting.

[0077] Exemplarily, the multifunctional water-fluorine interconnection machine operates in air source mode to supply heat to the indoor room. In this mode, although the second circulation loop 300 does not circulate, part of the heat is transferred to the circulating medium of the second circulation loop 300 through the second medium channel 102 of the indoor heat exchanger 4 for storage. When the first medium channel 101 of the outdoor heat exchanger 3 is frosted, and there is a need for defrosting and maintaining the need to supply heat to the indoor room, the multifunctional water-fluorine interconnection machine turns off the air source mode and operates in the first heating defrosting mode. The closure of the outdoor fan 3.2 effectively reduces the heat exchange between the outdoor air and the second medium channel 102 of the outdoor heat exchanger 3, ensuring the defrosting efficiency. The closure of the indoor fan 4.2 reduces the energy consumption of the multifunctional water-fluorine interconnection machine. Although the fifth valve 7.1 corresponding to the heat exchange device 7 is not opened here, it supplies heat to the indoor room through the heat stored in the air source mode. In this way, part of the heat of the circulating medium in the second circulation loop 300 is defrosted at the second medium channel 102 of the outdoor heat exchanger 3, and the other part of the heat is supplied to the indoor room through the heat exchange device 7.

[0078] Alternatively, if Figure 7 As shown, the multifunctional water-fluorine interconnected machine has a second heating and defrosting mode. The second heating and defrosting mode corresponds to the first circulation loop 200 running a heating cycle, the circulating water pump 5 is turned on, the second valve 3.1 and the fourth valve 5.1 are opened, and the first valve 6.1, the third valve 4.1 and the fifth valve 7.1 are closed.

[0079] In this embodiment, the first circulation loop 200 runs a heating cycle, and defrosts through the second circulation loop 300. The outdoor fan 3.2 is turned off, and the indoor fan 4.2 is turned on to supply hot air to the room. After the circulating water pump 5 is turned on, the water or antifreeze in the second circulation loop 300 begins to circulate, and when it flows through the second medium channel 102 of the outdoor heat exchanger 3, it exchanges heat with the first medium channel 101 of the outdoor heat exchanger 3 for defrosting, thereby supplying hot air to the room while defrosting. Compared with the common shutdown defrosting method, the defrosting method adopted by this multifunctional water-fluorine interconnected machine maintains the heating capacity while defrosting, which greatly improves energy efficiency and ensures the comfort level in the room.

[0080] Exemplarily, the multifunctional water-fluorine interconnection machine operates in air source mode to supply heat to the indoor space. In this mode, although the second circulation loop 300 does not circulate, part of the heat is transferred to the circulating medium of the second circulation loop 300 through the second medium channel 102 of the indoor heat exchanger 4 for storage. When the first medium channel 101 of the outdoor heat exchanger 3 is frosted, and there is a need for defrosting and maintaining the need to supply heat to the indoor space, the multifunctional water-fluorine interconnection machine turns off the air source mode and operates in the second heating and defrosting mode. The indoor fan 4.2 is turned on to form hot air to supply heat to the indoor space. In this way, part of the heat of the circulating medium in the second circulation loop 300 is exchanged at the second medium channel 102 of the outdoor heat exchanger 3 for defrosting, and the other part of the heat is exchanged at the second medium channel 102 of the outdoor heat exchanger 3 for maintaining the operation of the outdoor heat exchanger 3.

[0081] Alternatively, if Figure 8 As shown, the multifunctional water-fluorine interconnected machine has a dehumidification and reheating mode. The dehumidification and reheating mode corresponds to the first circulation loop 200 running a refrigeration cycle, the circulating water pump 5 is turned on, the second valve 3.1 and the fifth valve 7.1 are turned on, and the first valve 6.1, the third valve 4.1 and the fourth valve 5.1 are closed.

[0082] In this embodiment, the first circulation loop 200 runs a refrigeration cycle for dehumidification, and supplies heat to the room through the second circulation loop 300. The circulation flow of the second circulation loop 300 is the second medium channel 102 of the outdoor heat exchanger 3, the heat exchange device 7, the circulating water pump 5 and the second medium channel 102 of the outdoor heat exchanger 3. In addition, when water or refrigerant flows through the second medium channel 102 of the outdoor heat exchanger 3, it exchanges heat with the first medium channel 101 of the outdoor heat exchanger 3 and absorbs heat. This part of heat is supplied to the room through the heat exchange device 7 to increase the indoor temperature, thereby meeting the need to maintain the indoor temperature while dehumidifying.

[0083] Alternatively, if Fig. 9As shown, the multifunctional water-fluorine interconnection machine is applied to multiple rooms, each room is provided with an indoor heat exchanger 4 and a heat exchange device 7, a third valve 4.1 is provided on one side of the second medium channel 102 of each indoor heat exchanger 4, and a fifth valve 7.1 is provided on one side of each heat exchange device 7; the multifunctional water-fluorine interconnection machine has a small load heating mode. In the small load heating mode, the first circulation loop 200 runs a heating cycle, the circulating water pump 5 is turned on, the first valve 6.1, the second valve 3.1 and the fourth valve 5.1 are closed, the third valve 4.1 is turned on, and the state of the fifth valve 7.1 of the heat exchange device 7 corresponding to each room is controlled according to the heating demand of each room.

[0084] In this embodiment, the first circulation loop 200 runs a heating cycle, and at this time, the first medium channel 101 of the indoor heat exchanger 4 contains a high-temperature refrigerant. When the water or refrigerant in the second circulation loop 300 flows through the second medium channel 102 of the indoor heat exchanger 4, it exchanges heat with the high-temperature refrigerant. The circulation direction of the second circulation loop 300 is the second medium channel 102 of the indoor heat exchanger 4, the heat exchange device 7, the circulating water pump 5, and the second medium channel 102 of the indoor heat exchanger 4. In this way, the heat of the high-temperature refrigerant is transferred to the heat exchange device 7 through the second circulation loop 300.

[0085] In this embodiment, for a room with a rapid heating demand, the fifth valve 7.1 of the heat exchange device 7 corresponding to the room is opened, and the indoor fan 4.2 of the indoor heat exchanger 4 corresponding to the room is turned on. In this way, under the action of the indoor fan 4.2, the indoor air passes through the second air channel 104 and the first medium channel 101 and the second medium channel 102 of the indoor heat exchanger 4 to form hot air through heat exchange, quickly responding to the heating demand, and at the same time providing heat to the room through the heat exchange device 7.

[0086] In this embodiment, for a room with a duty heating demand, the fifth valve 7.1 of the heat exchange device 7 corresponding to the room is opened, and the indoor fan 4.2 of the indoor heat exchanger 4 corresponding to the room is closed. In this way, the heat exchange device 7 on the second circulation loop 300 is used to supply heat to the room, thereby ensuring the comfort of the user and meeting the duty heating demand.

[0087] In this embodiment, for a room without heating demand, the fifth valve 7.1 of the heat exchange device 7 corresponding to the room is closed, and the indoor fan 4.2 of the indoor heat exchanger 4 corresponding to the room is closed. In this way, the indoor heat exchanger 4 corresponding to the room without heating demand is still running, and compared with directly closing the expansion valve 4.3 of the indoor heat exchanger 4 corresponding to the room, the overall heat exchange area of ​​the multifunctional water-fluorine interconnection machine is increased, the condensation temperature is reduced, and thus the operation efficiency of the multifunctional water-fluorine interconnection machine is improved.

[0088] Alternatively, if Fig.10As shown, the multifunctional water-fluorine interconnection machine has an air source working mode. The air source working mode corresponds to the first circulation loop 200 running a refrigeration cycle or a heating cycle, the circulating water pump 5 is closed, the first valve 6.1 to the fifth valve 7.1 are closed, the outdoor fan 3.2 corresponding to the outdoor heat exchanger 3 is turned on, and the indoor fan 4.2 corresponding to the indoor heat exchanger 4 is turned on.

[0089] In this embodiment, the circulating water pump 5 is turned off, and the first valve 6.1 to the fifth valve 7.1 are closed, that is, the second circulation loop 300 is in a blocked state. The first circulation loop 200 runs a refrigeration cycle or a heating cycle, at which time the outdoor fan 3.2 drives the outdoor air to exchange heat with the first medium channel 101 of the outdoor heat exchanger 3 through the first air channel 103, and the indoor fan 4.2 drives the indoor air to exchange heat with the first medium channel 101 of the indoor heat exchanger 4 through the second air channel 104 to form cold air or hot air, thereby supplying cooling or heating to the room.

[0090] Alternatively, if Fig.11 As shown, the multifunctional water-fluorine interconnection machine has an intermittent heating start-up mode. The intermittent heating start-up mode corresponds to the first circulation loop 200 running a heating cycle, the circulating water pump 5 is turned on, the third valve 4.1 and the fifth valve 7.1 are turned on, the first valve 6.1, the second valve 3.1 and the fourth valve 5.1 are closed, and the indoor fan 4.2 corresponding to the indoor heat exchanger 4 is turned on.

[0091] In this embodiment, the first circulation loop 200 runs a heating cycle, and at this time, the first medium channel 101 of the indoor heat exchanger 4 contains a high-temperature refrigerant. The indoor fan 4.2 is turned on, and the indoor air exchanges heat with the first medium channel 101 of the indoor heat exchanger 4 to form hot air to supply heat to the room. In addition, the second medium channel 102 of the indoor heat exchanger 4 exchanges heat with the first medium channel 101, and the heat is transferred to the second circulation loop 300 and supplied to the room through the heat exchange device 7. In this way, heat is supplied to the room through the hot air and the heat exchange device 7 at the same time.

[0092] Optionally, the heat supply ratio of the indoor heat exchanger 4 and the heat exchange device 7 is adjusted according to user needs. In the intermittent heating start-up mode, the multifunctional water-fluorine interconnection machine can adjust the heat supply ratio of the indoor heat exchanger 4 and the heat exchange device 7 by adjusting the power of the indoor fan 4.2 and the power of the heat exchange device 7.

[0093] For example, in the intermittent heating start mode, if the user wants faster heating, the power of the indoor fan 4.2 and the power of the heat exchanger 7 are adjusted to make the heat supply ratio of the indoor heat exchanger 4 and the heat exchanger 7 2:1. In this way, the indoor heat is mainly supplied by hot air, thereby quickly responding to the user's temperature demand.

[0094] As another example, in the intermittent heating start mode, if the user wants more comfortable heating, the power of the indoor fan 4.2 and the power of the heat exchanger 7 are adjusted to make the heat supply ratio of the indoor heat exchanger 4 and the heat exchanger 7 1:2. In this way, the heat is mainly supplied to the room through the heat exchanger 7, thereby meeting the user's comfort needs.

[0095] Optionally, the multifunctional water-fluorine interconnection machine has an intermittent heating stable mode, which corresponds to the first circulation loop 200 running a heating cycle, the circulating water pump 5 is turned on, the third valve 4.1 and the fifth valve 7.1 are turned on, the first valve 6.1, the second valve 3.1 and the fourth valve 5.1 are closed, and the indoor fan 4.2 corresponding to the indoor heat exchanger 4 is turned off.

[0096] In this embodiment, the first circulation loop 200 runs a heating cycle, and at this time, the first medium channel 101 of the indoor heat exchanger 4 contains high-temperature refrigerant. The second medium channel 102 of the indoor heat exchanger 4 exchanges heat with the first medium channel 101, and the heat is transferred to the second circulation loop 300 and supplied to the room through the heat exchange device 7. The heat exchange device 7 includes a radiant heating terminal such as a ceiling-type heat radiator, which has a high comfort level. In addition, the indoor fan 4.2 is turned off, and the noise is low.

[0097] In combination with the above-mentioned embodiments, users can select and switch the appropriate operating mode of the multifunctional water-fluorine interconnection machine according to actual heating / heating / defrosting / dehumidification needs.

[0098] Exemplarily, the multifunctional water-fluorine interconnected machine is applied to the conference room scene. When the meeting time is short, the multifunctional water-fluorine interconnected machine runs the air source mode before the meeting, and uses hot air to preheat the conference room for rapid heating. When the meeting time is long, the multifunctional water-fluorine interconnected machine switches to the intermittent heating start mode, and heats the room through hot air and heat radiation of the heat exchange device 7 at the same time. In addition, the proportion of heat supply by hot air and heat radiation can be flexibly adjusted according to user needs. When the temperature of the conference room reaches the target temperature, the multifunctional water-fluorine interconnected machine can switch to the intermittent heating stable mode. At this time, the indoor fan 4.2 stops and only heats the room through heat radiation, with low indoor noise and high comfort. In this way, while meeting user needs, the energy efficiency of the system is greatly improved.

[0099] As another example, the multifunctional water-fluorine interconnection machine is applied to a home scene, with an indoor temperature of 10°C and a target temperature of 25°C. In order to meet the demand for reducing heating costs, the multifunctional water-fluorine interconnection machine runs external energy direct cooling / heating mode 1 between 10°C and 15°C, uses the source detection device 6 to input heat to the second circulation loop 300 and forms hot air at the indoor heat exchanger 4 to heat the room. In order to meet the needs of heating costs and comfort, the multifunctional water-fluorine interconnection machine runs external energy direct cooling / heating mode 2 between 16°C and 25°C, uses the source detection device 6 to input heat to the second circulation loop 300 and heats the room through thermal radiation.
