Description

Technical Field

[0001] This utility model relates to the field of fresh air dehumidification technology, and in particular to a purification and dehumidification system. Background Technology

[0002] Traditional central dehumidification systems, which use a single main unit for full-area air supply, have significant shortcomings:

[0003] 1) The main unit needs to overcome the resistance of the filter and the pipeline at the same time, resulting in a high total power of the compressor and the fan;

[0004] 2) Forced synchronous operation across the entire area results in a large amount of ineffective dehumidification, leading to energy waste;

[0005] 3) Long-distance air supply leads to uneven humidity control in the terminal area. Although existing technologies can adjust humidity by adding air valves, it is still difficult to balance the contradiction between system energy efficiency and regional control accuracy. Summary of the Invention

[0006] To address the aforementioned problems, the present invention aims to provide a purification and dehumidification system in which separate supply and exhaust fans are installed in multiple dehumidification and purification zones to overcome duct resistance, reduce the power of the main unit, and extend equipment life. The system supports independent control and flexible speed adjustment in multiple zones, significantly reduces system energy consumption, and achieves independent dehumidification in different zones with continuously adjustable air volume.

[0007] To achieve the above objectives, the present invention adopts the following technical solution:

[0008] A purification and dehumidification system, characterized in that: it includes a dehumidification and purification machine, the dehumidification and purification machine includes a shell, an air inlet is provided on one side of the shell and an air outlet is provided on the other side, an air inlet pipe is connected to the air inlet, a first diversion pipe is connected to the end of the air inlet pipe, a plurality of first ventilation ducts are connected to the first diversion pipe, and a first DC frequency converter fan for exhausting air into the room is provided in the first ventilation duct.

[0009] An exhaust duct is connected to the exhaust outlet, and a second branch pipe is connected to the end of the exhaust duct. Several second ventilation ducts are connected to the second branch pipe, and a second DC variable frequency fan for supplying air to the room is installed in the second ventilation duct. The ends of adjacent first ventilation ducts and second ventilation ducts are located in the same dehumidification and purification area.

[0010] A ventilation cavity is formed inside the housing, and a heat pump dehumidification system is installed inside the ventilation cavity. The heat pump dehumidification system includes a compressor, a condenser and an evaporator connected in sequence. The evaporator is located near the air inlet, and the condenser is located near the air outlet. A fan is installed inside the ventilation cavity between the condenser and the air outlet.

[0011] Preferably, the first ventilation duct is provided with a first check valve on the front side of the first DC inverter fan to prevent backflow of air discharged from the dehumidification and purification area.

[0012] Preferably, the second ventilation duct is provided with a second check valve on the front side of the second DC inverter fan to prevent backflow of air entering the dehumidification and purification area.

[0013] Preferably, a filter screen is provided between the air inlet and the evaporator.

[0014] Preferably, the heat pump dehumidification system also includes an electronic expansion valve disposed between the condenser and the evaporator.

[0015] This utility model adopts the above-mentioned technical solution, in which a first diversion pipe and a second diversion pipe are respectively set at the air inlet and air outlet of the dehumidifier. Several first ventilation ducts branch off from the first diversion pipe, and a first DC inverter fan is installed in each of the first ventilation ducts to exhaust air from the room and overcome the duct pressure. Several second ventilation ducts branch off from the second diversion pipe, and a second DC inverter fan is installed in each of the second ventilation ducts to supply air to the room and overcome the duct pressure. One first ventilation duct and one second ventilation duct correspond to one room. When the room needs ventilation and dehumidification, the first and second DC inverter fans start and activate the dehumidifier. The air intake duct draws in room air, overcoming filter resistance, and passes it through the filter (which removes dust and other impurities). The compressor compresses the refrigerant into a high-temperature, high-pressure gas, which is then cooled to a liquid state by the condenser and enters the evaporator. The refrigerant in the evaporator rapidly evaporates, absorbing heat and lowering the evaporator surface temperature below the dew point, causing water vapor in the air to condense into water droplets. The dried, cool air then passes through the condenser, absorbing the heat released by the refrigerant and warming up, forming warm, dry air that is then delivered into the room through the exhaust vent. The condensate formed during dehumidification is discharged through the drain pipe of the dehumidifier, thus completing dehumidification and ventilation, providing the following beneficial effects:

[0016] ① Each area (room) can independently operate the first DC inverter fan and the second DC inverter fan to activate the dehumidifier and purifier (the power of dehumidification and ventilation in all rooms is equivalent to that of traditional systems), achieving precise regional humidity control and rapid response, avoiding forced linkage of the entire area which would cause a large amount of ineffective dehumidification and energy waste, and significantly reducing overall operating energy consumption.

[0017] ② In the dehumidifier, the compressor and fan only need to overcome the filter resistance, reduce power, and significantly reduce the noise level of the equipment (the first DC inverter fan and the second DC inverter fan only need to overcome the pipe resistance, and the noise is also low), reduce the equipment load, and extend the service life of the equipment.

[0018] ③ The dehumidification and ventilation adopts an optimized flow channel design to reduce the size of the dehumidification and purification machine. The supply and exhaust air in a single room are carried out through different pipes to reduce airflow interference and maintain dehumidification stability. At the same time, the fresh air and exhaust air volume are matched in real time to maintain dehumidification stability (the intake air volume is matched in real time when starting a single room and multiple rooms respectively).

[0019] ④ The indoor piping adopts a compact pipe design to reduce installation space requirements and improve space utilization. The system can be freely expanded according to the number of terminals, making selection and configuration convenient. Attached Figure Description

Furthermore, "above," "over," and "on top" of the second feature includes the first feature directly above or diagonally above the second feature, or simply indicates that the first feature is at a higher horizontal level than the second feature. "Below," "below," and "under" the second feature includes the first feature directly below or diagonally below the second feature, or simply indicates that the first feature is at a lower horizontal level than the second feature.

[0026] like Figure 1 The purification and dehumidification system shown includes a dehumidification and purification machine 1. The dehumidification and purification machine 1 includes a housing. An air inlet 2 is provided on one side of the housing and an air outlet 3 is provided on the other side. An air inlet pipe 4 is connected to the air inlet 2. A first diversion pipe 5 is connected to the end of the air inlet pipe 4. A plurality of first ventilation ducts 6 are connected to the first diversion pipe 5. A first DC frequency converter fan 7 for exhausting air from the room is provided in the first ventilation duct 6.

[0027] The exhaust vent 3 is connected to an exhaust pipe 8, and the end of the exhaust pipe 8 is connected to a second branch pipe 9. The second branch pipe 9 is connected to several second ventilation ducts 10, and the second ventilation ducts 10 are equipped with a second DC variable frequency fan 11 for supplying air to the room; the ends of adjacent first ventilation ducts 6 and second ventilation ducts 10 are located in the same dehumidification and purification area 12.

[0028] A ventilation cavity 13 is formed inside the housing. A heat pump dehumidification system is installed inside the ventilation cavity 13. The heat pump dehumidification system includes a compressor 14, a condenser 15 and an evaporator 16 connected in sequence. The evaporator 16 is close to the air inlet 2 and the condenser 15 is close to the air outlet 3. A fan 17 is installed inside the ventilation cavity 13 between the condenser 15 and the air outlet 3.

[0029] In the above technical solution, a first diversion pipe and a second diversion pipe are respectively installed at the air inlet and exhaust outlet of the dehumidifier. Several first ventilation ducts branch off from the first diversion pipe, and a first DC inverter fan is installed inside each first ventilation duct to exhaust air from the room and overcome duct pressure. Several second ventilation ducts branch off from the second diversion pipe, and a second DC inverter fan is installed inside each second ventilation duct to supply air to the room and overcome duct pressure. One first ventilation duct and one second ventilation duct correspond to one room. When the room needs ventilation and dehumidification, the first and second DC inverter fans start and activate the dehumidifier. The system draws in room air through the intake duct, overcoming filter resistance. The filter removes dust and other impurities. The compressor compresses the refrigerant into a high-temperature, high-pressure gas, which is then cooled to a liquid state by the condenser and enters the evaporator. In the evaporator, the refrigerant rapidly evaporates, absorbing heat and lowering the evaporator surface temperature below the dew point, causing water vapor in the air to condense into water droplets. The dried, cool air then passes through the condenser, absorbing the heat released by the refrigerant and warming up, forming warm, dry air that is then delivered into the room through the exhaust vent. The condensate formed during dehumidification is discharged through the dehumidifier's drain pipe, thus completing dehumidification and ventilation.

[0030] Each area (room) can independently operate the first DC inverter fan and the second DC inverter fan to activate the dehumidifier and air purifier (when all rooms are turned on for dehumidification and ventilation, the power is equivalent to that of traditional systems), achieving precise regional humidity control and rapid response. This avoids forced linkage of the entire area, which would result in a large amount of ineffective dehumidification and energy waste, and significantly reduces overall operating energy consumption.

[0031] In dehumidifiers, the compressor and fan only need to overcome the filter resistance, reduce power, and significantly reduce the noise level of the equipment (the first and second DC inverter fans only need to overcome the pipe resistance, and the noise is also low), reducing the equipment load and extending the service life of the equipment.

[0032] The dehumidification and ventilation system employs an optimized flow channel design to reduce the size of the dehumidifier. Supply and exhaust air within a single room are routed through different ducts, minimizing airflow interference and maintaining dehumidification stability. Simultaneously, the system dynamically adjusts the fresh air and exhaust air volumes in real-time to maintain dehumidification stability (intake air volume is matched separately for single-room and multi-room operation), meaning the compressor and fan frequencies are adjusted based on the difference between the set humidity and the actual humidity. The indoor ductwork features a compact design to reduce installation space requirements and improve space utilization. Furthermore, the system can be freely expanded based on the number of terminal units, making selection and configuration convenient.

[0033] Furthermore, a first check valve 18 is provided on the front side of the first DC inverter fan 7 in the first ventilation duct 6 to prevent backflow of air discharged from the dehumidification and purification area 12. In this technical solution, the first check valve prevents backflow of air in the duct and ensures the stability of the exhaust air.

[0034] Furthermore, the second ventilation duct 10 is provided with a second check valve 19 on the front side of the second DC inverter fan 11 to prevent backflow of air into the dehumidification and purification area 12. In this technical solution, the second check valve prevents backflow of air into the room and ensures the stability of the incoming air.

[0035] The aforementioned double check valve assembly achieves airflow isolation.

[0036] Furthermore, a filter screen 20 is provided between the air inlet 2 and the evaporator 16. In this technical solution, the filter screen is used to filter the air exhausted from the room, remove dust and other impurities, and ensure that the air entering the room is clean.

[0037] Furthermore, the heat pump dehumidification system also includes an electronic expansion valve 21 disposed between the condenser 15 and the evaporator 16. In this technical solution, the electronic expansion valve is used for throttling and pressure reduction to protect the system.
