[0031] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0032] See also Figure 1-Figure 11The present invention provides a technical solution: a water-source fresh air unit with independently controllable temperature and humidity, comprising: a shell 1; a condensation and dehumidification component is placed inside the shell 1, the condensation and dehumidification component comprises a dehumidification air duct 5 with a water collecting tank 10 at the bottom, the dehumidification air duct 5 is a box body with an opening at one end, one end of the dehumidification air duct 5 is in contact with and fixed to the shell 1, an evaporator 7 and a condenser 8 are vertically and parallelly installed inside the dehumidification air duct 5, the evaporator 7 is located on the air inlet side of the dehumidification air duct 5, and one end of the dehumidification air duct 5 is fixedly connected to a fan 3 for introducing indoor or outdoor air; a floor heating water source heat exchange component is placed on one side of the dehumidification air duct 5, the floor heating water source heat exchange component comprises a heat exchanger 9 connected to the floor heating and a heat exchange pipe 6 placed between the evaporator 7 and the condenser 8; an auxiliary function component is placed on the top of the dehumidification air duct 5, ... The auxiliary function component includes a sealing box 29 for storing high pressure. The bottom of the sealing box 29 is connected to a plurality of nozzles 30 facing the evaporator 7 through a solenoid valve, which is used for auxiliary cooling and cleaning of the fins of the evaporator 7. A semiconductor refrigeration plate 34 is fixedly connected to one side of the sealing box 29. The cooling end of the semiconductor refrigeration plate 34 cools the inside of the sealing box 29 and cooperates with the nozzle 30 to assist in cooling the evaporator 7. The heating end of the semiconductor refrigeration plate 34 heats the air entering the dehumidification air duct 5 and increases the temperature difference between the air and the evaporator 7. The fresh air component is placed inside the shell 1. The fresh air component includes an outdoor air inlet pipe 16 connected to the fan 1 3 and a fan 2 25 for pressurizing the sealing box 29 and exhausting indoor air.

[0033] It should be noted that the present invention is provided with a controller and a corresponding operation panel, and the controller is electrically connected to each electrical component. When the indoor air humidity is high, the fan 1 3 draws the inside of the dehumidification air duct 5 into a negative pressure, and the compressor 15 and the corresponding evaporator 7 and condenser 8 start working. Under the action of the negative pressure, the indoor air enters the dehumidification air duct 5, contacts the evaporator 7 and is liquefied. After the air is dehumidified, it is discharged through the fan 1 3. When the air humidity is high, the fan 2 25 blows air into the sealing box 29, and the semiconductor refrigeration sheet 34 starts working. After the air is cooled by the semiconductor refrigeration sheet 34 in the sealing box 29, it is blown toward the evaporator 7 through the nozzle 30, and the fins of the evaporator 7 are cooled for a second time. In addition, the heating end of the semiconductor refrigeration sheet 34 heats the air entering the dehumidification air duct 5, thereby increasing the temperature difference between the air and the evaporator 7. The greater the temperature difference, the faster the heat transfer rate and the higher the heat exchange efficiency, because the temperature difference provides the power for heat to be transferred from the high-temperature fluid to the low-temperature fluid. When the evaporator 7 needs to be cleaned, the water inside the sump 10 is injected into the sealing box 29 through the water pump 11, and the inside of the sealing box 29 is pressurized through the fan 25 and the high-pressure air duct 26. When the solenoid valve of the nozzle 30 is opened, the high-pressure water performs high-pressure flushing on the evaporator 7 to achieve self-cleaning, and when the temperature is lowered, the heat exchanger 9 and the heat exchange tube 6 can be used for heat exchange, so that the dehumidified air can be controlled and discharged after being heated through the heat exchange tube 6 to achieve air temperature adjustment. If a fresh air function room needs to be realized, the indoor air can be discharged through the fan 25, and the channel connecting the fan 3 and the dehumidification air duct 5 is closed, so that the fan 3 introduces outdoor fresh air into the room through the outdoor air inlet pipe 16.

[0034] like Figure 4 , 5 As shown in , 6, 7, and 8, one end of the dehumidification air duct 5 is fixedly connected to the shell 1, and a plurality of air inlets 4 are provided at positions of the shell 1 corresponding to the dehumidification air duct 5. A ventilation hole is provided at one end of the dehumidification air duct 5 away from the air inlet 4. Two sealing plates 19 are slidably connected to the outer side of the dehumidification air duct 5 and at positions corresponding to the ventilation holes. A spring 20 is installed between the two sealing plates 19. Magnets 22 are fixedly connected to the ends of the sealing plates 19. Electromagnets 21 are fixedly connected to the ends of the dehumidification air duct 5 and at positions corresponding to the magnets 22. When the electromagnet 21 is energized When the magnetic pole is the same as the magnet 22 and the repulsive force is greater than the elastic force of the spring 20, one end of the dehumidification air duct 5 is fixedly connected to the switching air duct 18, the switching air duct 18 is connected to the input end of the fan 3, an air outlet 2 is provided on the top of the shell 1, and the output end of the fan 3 is connected to the air outlet 2 through a pipeline. A humidity sensor 12 is fixedly connected to one side of the shell 1, one end of the outdoor air inlet pipe 16 is connected to the switching air duct 18, and a solenoid valve is installed in the middle of the outdoor air inlet pipe 16, and an air filter 17 is installed inside the outdoor air inlet pipe 16.

[0035] It should be noted that when the humidity sensor 12 of the present invention detects that the humidity is relatively high, the signal is transmitted to the controller, and the controller controls the dehumidification component to work. In the natural state, the spring 20 pushes the sealing plate 19 to both sides, and the dehumidification air duct 5 is connected to the fan 3 through the ventilation hole. The fan 3 draws the dehumidification air duct 5 into a negative pressure. Under the action of the negative pressure, the indoor air enters the dehumidification air duct 5 through the air inlet 4, and then contacts the evaporator 7 and the condenser 8 to achieve dehumidification. The outdoor air inlet pipe 16 passes through the middle of the wall and is connected to the outdoors. When the equipment needs to be switched to the fresh air system, the controller controls the electromagnet 21 to be energized. When the electromagnet 21 is energized, it contacts the magnet 2 2 magnetic poles are the same. Under the action of repulsion, the sealing plate 19 moves toward the middle along the tracks on both sides and compresses the spring 20 to block the ventilation holes of the dehumidification air duct 5. At this time, the outdoor air inlet pipe 16, the switching air duct 18 and the fan 3 form a single air path. The solenoid valve of the outdoor air inlet pipe 16 is opened. When the fan 3 is working, the input end of the fan 3 introduces the outdoor wind into the switching air duct 18 through the outdoor air inlet pipe 16 and then discharges it into the room through the fan 3 and the air outlet 2. When the air enters the outdoor air inlet pipe 16, it is filtered by the air filter 17. The air filter 17 is a HEPA filter or an activated carbon filter, so as to ensure the quality of the air entering the room.

[0036] like Figure 2 , 4 As shown in , 5, 6, and 7, a compressor 15 is provided inside the shell 1, the compressor 15 is connected to the condenser 8 through a pipeline, the condenser 8 is connected to the throttling device through a pipeline, the throttling device is connected to the evaporator 7 through a pipeline, and the evaporator 7 is connected to the compressor 15 through a pipeline.

[0037] It should be noted that the throttling device of the present invention includes a capillary tube and an expansion valve. The compressor is responsible for compressing the refrigerant to provide power for the refrigeration cycle. The condenser is responsible for cooling the high-temperature and high-pressure refrigerant gas discharged from the compressor into a liquid or a gas-liquid mixture, thereby releasing heat. The evaporator utilizes the principle that liquid low-temperature refrigerant is easy to evaporate under low pressure to absorb heat in the air and condense water vapor in the air into liquid water. The throttling device converts the medium-temperature and high-pressure refrigerant gas into a low-temperature and low-pressure refrigerant liquid after throttling.

[0038] like Figure 2 , 4As shown in Figures 5, 6, 9, 10 and 11, the heat exchanger 9 is fixedly connected to the inside of the shell 1. The heat exchanger 9 is a plate heat exchanger. The ends of the heat exchanger 9 are provided with a floor heating hot water inlet pipe 13 and a floor heating return pipe 14. A water level sensor is installed inside the water collecting tank 10, and a water pump 11 is fixedly connected to one end of the water collecting tank 10. The input end of the water pump 11 is connected to the water collecting tank 10, and the output end of the water pump 11 is respectively connected to the heat exchange pipe 6, the floor heating return pipe 14 and the sealing box 29 through pipelines and valves. The water outlet end of the heat exchange pipe 6 is connected to the floor heating return pipe 14 for returning water to the floor heating component.

[0039] It should be noted that the present invention connects the heat exchanger 9 to the floor heating pipeline through the floor heating hot water inlet pipe 13 and the floor heating return pipe 14, so that the hot water of the floor heating enters through the floor heating hot water inlet pipe 13 and then flows into the floor heating system through the floor heating return pipe 14. When heating the dehumidified air, the water pump 11 draws the water in the water collection tank 10 into the heat exchanger 9, and the heat in the floor heating water is transferred to the water in the heat exchange pipe 6 through the heat exchange wall of the heat exchanger. After the water is heat exchanged in the heat exchanger 9, it becomes hot water, and the hot water enters the front of the condenser 8 through the heat exchange pipe 6. The water in the heat exchange pipe 6 enters the floor heating return pipe 14 for recycling after circulation, and the air is heated after contacting the heat exchange pipe 6, and then enters the condenser 8 and is discharged, thereby achieving air heating, and when there is more water in the water collection tank 10, the controller controls the water pump 11 to discharge the water in the water collection tank 10 into the floor heating return pipe 14 through the water pipe and the one-way valve through the water level sensor.

[0040] like Figure 5 , 6 As shown in Figures 7, 9, 10 and 11, the sealing box 29 is fixedly connected to the top of the dehumidification air duct 5, and a pressure sensor 37 and a metal needle 35 are fixedly connected to the inside of the sealing box 29. One end of the metal needle 35 is connected to the cooling end of the semiconductor refrigeration plate 34. A heat dissipation air duct 32 is fixedly connected to one side of the sealing box 29. The heating end of the semiconductor refrigeration plate 34 is placed in the heat dissipation air duct 32. The bottom of the heat dissipation air duct 32 is connected to the dehumidification air duct 5. Both sides of the heat dissipation air duct 32 are provided with heat dissipation fans 33 for blowing air into the heat dissipation air duct 32.

[0041] It should be noted that when the semiconductor refrigeration sheet 34 of the present invention is working, the semiconductor refrigeration sheet 34 transmits the low temperature of the semiconductor refrigeration sheet 34 to the sealed box 29 through the metal needle 35, and the fan 25 blows the wind into the sealed box 29 through the high-pressure air duct 26 and the one-way valve 31, so that the air in the sealed box 29 is cooled, and then the valve of the nozzle 30 is opened. Under the action of the wind pressure, the nozzle 30 blows the cold wind to the evaporator 7, so that the fins of the evaporator 7 are cooled here, and the heat dissipation fan 33 is used to blow the inside of the heat dissipation duct 32, and the semiconductor The heating end of the semiconductor refrigeration plate 34 is placed in the heat dissipation duct 32, and the bottom of the heat dissipation duct 32 is connected to the dehumidification duct 5, so that the hot air from the heat dissipation duct 32 enters the dehumidification duct 5 and is located at the air inlet position of the evaporator 7, so that the temperature of the air entering the dehumidification duct 5 is increased, and the dehumidification efficiency is improved through the large temperature difference. Moreover, when the fan 25 is not working, the heat dissipation fan 33 and the same semiconductor refrigeration plate 34 work alone, which can heat the incoming air and make the air temperature after dehumidification higher, so that the temperature after dehumidification can be adjusted.

[0042] like Figure 5 , 6 As shown in Figures 7, 9, 10 and 11, the fan 25 is fixedly connected to the bottom of the inner wall of the shell 1, and a ventilation inlet 36 is provided at the bottom of the shell 1 corresponding to the input end of the fan 25. The output end of the fan 25 is fixedly connected to the wind direction switching box 24 through the exhaust duct, and one side of the wind direction switching box 24 is fixedly connected to the ventilation exhaust duct 23 for exhausting the indoor air. The interior of the wind direction switching box 24 is slidably connected with a sealing plate slide 27 for blocking the exhaust duct, and the interior of the wind direction switching box 24 is fixedly connected with an electric push rod 28 for driving the sealing plate slide 27 to slide. The top of the output end of the fan 25 is fixedly connected to a high-pressure air duct 26, one end of the high-pressure air duct 26 is connected to a sealing box 29, and a one-way valve 31 is fixedly connected to the middle of the high-pressure air duct 26. When the sealing plate slide 27 blocks the exhaust duct, the fan 25 cooperates with the high-pressure air duct 26 and the one-way valve 31 to blow air and pressurize the sealing box 29.

[0043] It should be noted that when the present invention performs fresh air ventilation, the fan 1 3 introduces external air into the room, the electric push rod 28 drives the sealing plate slide 27 to slide to one side, so that the fan 2 25 is connected to the ventilation exhaust duct 23 through the wind direction switching box 24, and the fan 2 25 draws indoor air into the wind direction switching box 24 from the ventilation inlet 36 at the bottom of the shell 1 and discharges it through the ventilation exhaust duct 23, thereby realizing the replacement of indoor air. When the evaporator 7 is high-pressure flushed, the electric push rod 28 drives the sealing plate slide 27 to close the wind direction switching box 24, so that the fan 25 and the high-pressure air duct 26 form a single The air duct draws the water inside the water collection tank 10 into the sealing box 29 through the water pump 11. One end of the water pump 11 is connected to the sealing box 29 through a one-way valve. When the water is transported, the fan 25 generates an airflow, which is transmitted to the one-way valve 31 through the high-pressure air duct 26. The one-way valve 31 ensures that the airflow enters the sealing box 29 in one direction, thereby blowing and pressurizing the inside of the sealing box 29. When the pressure sensor 37 detects that the pressure reaches the preset value, the controller controls the solenoid valve of the nozzle 30 to open, so that the water in the sealing box 29 is sprayed toward the evaporator 7 with high pressure, so as to perform high-pressure flushing on the evaporator 7, thereby achieving self-cleaning.
