Description

Technical Field

[0001] This invention belongs to the field of air conditioning technology, and in particular relates to an energy-saving integrated air conditioning and dehumidification unit that combines fresh air purification and dehumidification. Background Technology

[0002] An air conditioner is a device that can partially or completely regulate the temperature, humidity, airflow, and cleanliness of air in a closed space, so that the air parameters of the target environment meet the requirements. A fresh air conditioner is a healthy and comfortable air conditioner with a fresh air function. It uses a centrifugal fan to realize the circulation and ventilation between indoor air and outdoor air, and also has the function of purifying the air.

[0003] An existing document (publication number CN207407453U) discloses a fresh air purification air conditioning dehumidification integrated unit, including a base and a housing. The housing is fixed on the base and a controller is installed on the housing. The housing contains, from left to right, a condenser, a compressor, a fresh air purifier, an evaporator, a dehumidifier reheater, and a blower. A temperature and humidity sensor is installed on the air inlet of the fresh air purifier.

[0004] As is known from existing technology, dehumidifying air is accompanied by a decrease in air temperature, which results in the final output air being low-temperature air. In order to maintain a constant temperature, the air circulating in the air conditioning system needs to be heated. Generally, the dehumidified air is heated by direct electric heating. However, the dehumidification method of directly heating the output air again is relatively energy-intensive. Summary of the Invention

[0005] Given the existing technology that dehumidifying air results in a decrease in air temperature, leading to low-temperature output air, and the need to reheat the circulated air in order to maintain a constant temperature in air conditioning systems, which is typically done through direct electric heating, this dehumidification method is energy-intensive. Therefore, this invention proposes an energy-saving integrated air purification and dehumidification unit.

[0006] This invention proposes an energy-saving integrated air purification and dehumidification unit, comprising a body, which is divided into a front part, a rear part, and two side parts. The front part of the body has an upper outlet and a lower outlet at different positions through two louvers. The two side parts of the body are provided with side plates with openings. The rear part of the body also has a rear outlet through louvers. A hot space is provided in the upper part of the body, and a connecting space and a cold space are formed in the lower part of the body through a middle plate.

[0007] A condenser is installed in the hot space, and two first impellers are provided on one side of the condenser. An evaporator is fixedly installed in the cold space, and a compressor is fixedly installed in the connecting space. A water tank is provided below the evaporator.

[0008] The hot space has air intake spaces on both the left and right sides. The front and rear ends of the hot space are connected to the front and rear parts, respectively. A filter plate is installed in the air intake space and faces the opening. The air intake space is connected to the cold space. The cold space and the connecting space are connected to each other and a second fan is provided between them. The connecting space is connected to the hot space. The front and rear parts of the body are equipped with partitions opposite to the louvered fan.

[0009] Preferably, the body is provided with a drive mechanism corresponding to the louvered fan. The louvered fan includes multiple blades, and a mounting plate is connected to the middle of one end of each blade via a rotating shaft. The mounting plate is fixedly installed on the body. The drive mechanism includes a rack and pinion and is used to drive the louvered fan to deflect around the rotating shaft.

[0010] Preferably, grooves are provided on both sides of the front and rear of the machine body, the drive mechanism is installed in the grooves, and sliding grooves are provided on the inner wall of the grooves at the upper and lower ends of the rack. A slider is slidably connected in the sliding groove, and a plug shaft is fixedly connected to the slider. A connecting shaft is fixedly connected to both the upper and lower ends of the rack, and the two plug shafts are slidably inserted into the two connecting shafts respectively.

[0011] Preferably, a rotating component is fixedly connected to the end of the louver fan away from the rotating shaft. The rotating component is located on one side of the louver fan away from the rotating shaft. Multiple strip grooves are provided on the rack, and multiple rotating components are slidably inserted into the strip grooves. A motor is fixedly installed on the body, and a gear shaft is fixedly connected to the drive end of the motor. The gear shaft meshes with the rack.

[0012] Preferably, each blade has a rubber layer on its upper and lower surfaces, the partition has multiple holes, and the edge of the partition has an annular rubber ring. When the multiple blades deflect and stick together, the multiple blades form a sealed louver that presses against the annular rubber ring.

[0013] Preferably, the compressor is connected to the condenser and the evaporator respectively through pipes. A fixed shaft is fixedly connected to the condenser and the evaporator. The upper and lower ends of the fixed shaft on the condenser are fixedly connected to the inner wall of the hot space, and the upper and lower ends of the fixed shaft on the evaporator are fixedly connected to the inner wall of the cold space and pass through the water tank in a sealed manner.

[0014] Preferably, the left and right sides of the thermal space are respectively formed by side plates to form two air intake spaces, and the filter plate is provided with a mounting groove for placing the motor.

[0015] Preferably, one end of the water tank is connected to a water pipe for outputting condensate, the lower surface of the water tank is inclined, and one end of the water tank is provided with a central trough with a flat lower surface, and the water pipe is connected to one side of the central trough.

[0016] Preferably, the upper end of the intermediate plate is connected to an inclined plate, the upper end of the inclined plate is fixedly connected to the inner wall of the air intake space located on one side of the cold space, the lower end of the inclined plate is fixedly connected to the intermediate plate, and the second impeller is installed at the position where the cold space and the connecting space are connected.

[0017] Compared with the prior art, the beneficial effects of the present invention are:

[0018] 1. When the refrigerant passes through the condenser, it heats the surrounding air. The first fan is activated to guide the hot air, so that the hot air is output through the upper outlet. At this time, the cold air and hot air will mix together when they are output from the same side. The hot air has a heating and warming effect on the cold air, so the temperature will not drop during the dehumidification process. This device combines the dehumidification process with the cooling and heating process. Moreover, during dehumidification, there is no need for an additional resistance wire to reheat the cold air, which can effectively save energy consumption.

[0019] 2. When cooling the room, close the louvers at the top outlet to form a panel, thereby blocking the partition at the top outlet. At the same time, open the louvers at the rear outlet so that the partition at the rear outlet is open, and finally output cold air through the bottom outlet.

[0020] 3. When heating is required in the room, close the louvers at the lower outlet to seal the partition there, open the louvers at the rear outlet, and unfold the louvers at the upper outlet to open the partition there. As the first impeller rotates, air enters the hot space through the rear outlet and is heated by the condenser to form hot air, which is then output through the upper outlet. At this time, the output is hot air to heat the indoor environment. Attached Figure Description

[0032] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments.

[0033] Reference Figures 1-10An energy-saving air purification and dehumidification integrated unit includes a body 1, which is divided into a front part, a rear part and two sides. The front part of the body 1 has an upper outlet 2 and a lower outlet 3 formed by two louvered fans 6. The two sides of the body 1 are provided with side plates 4 with openings 5. The rear part of the body 1 also has a rear outlet 7 formed by louvered fans 6. A hot space 10 is provided in the upper part of the body 1. A connecting space 14 and a cold space 12 are formed in the lower part of the body 1 through a middle plate 11.

[0034] A condenser 21 is installed in the hot space 10, and two first fan wheels 34 are provided on one side of the condenser 21. An evaporator 31 is fixedly installed in the cold space 12, and a compressor 24 is fixedly installed in the connecting space 14. A water tank 15 is provided below the evaporator 31.

[0035] The hot space 10 has air intake spaces 13 on both sides. The front and rear ends of the hot space 10 are connected to the front and rear parts respectively. The air intake space 13 is equipped with a filter plate 9 that is directly opposite the opening 5. The air intake space 13 is connected to the cold space 12. The cold space 12 is connected to the connecting space 14 and a second fan wheel 30 is provided between them. The connecting space 14 is connected to the hot space 10. The front and rear parts of the body 1 are equipped with partitions 8 opposite to the louvered fan 6.

[0036] The main body 1 is equipped with a drive mechanism corresponding to the louvered fan 6. The louvered fan 6 includes multiple blades, and a mounting plate 20 is connected to the middle of one end of each blade via a rotating shaft. The mounting plate 20 is fixedly mounted on the main body 1. The drive mechanism includes a rack 17 and is used to drive the louvered fan 6 to deflect around the rotating shaft. When guiding air, the drive mechanism can drive each louvered fan 6 to deflect, thereby guiding the passing air, changing the direction of the air, and achieving the effect of opening and closing the partition 8.

[0037] The front and rear sides of the body 1 are provided with grooves, and the drive mechanism is installed in the grooves. Slide grooves 26 are provided on the inner wall of the grooves at both ends of the rack 17. A slider 27 is slidably connected within the slide grooves 26, and a pin 28 is fixedly connected to the slider 27. Connecting shafts 25 are fixedly connected to both ends of the rack 17, and the two pins 28 slide through the two connecting shafts 25 respectively. When the drive mechanism is operating, the rack 17 needs to be limited. The louvered fan 6 rotates in an arc, and the connecting shafts 25 can move back and forth on the pins 28. The pins 28 can slide up and down within the slide grooves 26 via the sliders 27. Therefore, during use, the rack 17 can adapt to the oscillation trajectory of the louvered fan 6, and the pins 28 also provide support for the rack 17.

[0038] A rotating component 35 is fixedly connected to the end of the louvered fan 6 away from the axis of rotation. The rotating component 35 is located on the side of the louvered fan 6 away from the axis of rotation. Multiple slots are formed on the rack 17, and multiple rotating components 35 are slidably inserted into these slots. A motor 18 is fixedly mounted on the body 1, and a gear shaft 29 is fixedly connected to the drive end of the motor 18. The gear shaft 29 meshes with the rack 17. When the blade orientation needs to be changed, the motor 18 drives the gear shaft 29 to rotate via its drive end. When the gear shaft 29 rotates, it pushes the rack 17 to move up and down. As the rack 17 moves up and down, it affects the deflection angle of each louvered fan 6 through the rotating components 35. One rotating component 35 is inserted into each slot. Since the louvered fan 6 can only rotate along the axis of rotation, the rack 17 influences the height of the rotating component 35, causing the louvered fan 6 to deflect and thus change the airflow direction. The gear shaft 29 is relatively long.

[0039] Each blade has a rubber layer on both its upper and lower surfaces. The partition 8 has multiple holes, and an annular rubber ring is located at its edge. When multiple blades deflect and adhere to each other, the resulting sealed louver 6 presses against the annular rubber ring. When the blades deflect to their mated state, the rubber layers adhere to each other, forming a sealed plate surface. This plate surface then presses against the annular rubber ring, sealing the partition 8 and thus enclosing the area.

[0040] The compressor 24 is connected to the condenser 21 and the evaporator 31 via pipes 22. A fixed shaft 23 is fixedly connected to both the condenser 21 and the evaporator 31. The upper and lower ends of the fixed shaft 23 on the condenser 21 are fixedly connected to the inner wall of the hot space 10, and the upper and lower ends of the fixed shaft 23 on the evaporator 31 are fixedly connected to the inner wall of the cold space 12, and the shaft passes through the water tank 15 in a sealed manner. The condenser 21 is fixedly installed in the hot space 10 via the fixed shaft 23, and the evaporator 31 is also fixedly installed in the cold space 12 via the fixed shaft 23.

[0041] The hot space 10 has two air intake spaces 13 formed on the left and right sides by side plates 4. The filter plate 9 is provided with a mounting groove 19 for placing the motor 18. Since the drive mechanism is located close to the air intake space 13, the mounting groove 19 is provided on the filter plate 9 to store the motor 18.

[0042] One end of the water tank 15 is connected to a water pipe 16, which is used to output condensate. The lower surface of the water tank 15 is inclined, and one end of the water tank 15 is provided with a collection tank 33 with a flat lower surface. The water pipe 16 is connected to one side of the collection tank 33. During cooling or dehumidification, water will be generated on the surface of the evaporator 31. The water drips into the water tank 15 and is collected. Finally, it flows into the collection tank 33 and is output through the water pipe 16.

[0043] An inclined plate 32 is connected to the upper end of the intermediate plate 11. The upper end of the inclined plate 32 is fixedly connected to the inner wall of the intake space 13 located on one side of the cold space 12, and the lower end of the inclined plate 32 is fixedly connected to the intermediate plate 11. The second impeller 30 is installed at the position where the cold space 12 and the connecting space 14 are connected. The inclined plate 32 connects the intake space 13 and the connecting space 14, so that when air enters through the intake space 13, it is guided by the rotation of the second impeller 30, and then enters the cold space 12 through the connecting space 14, and is then cooled and output by the evaporator 31.

[0044] When a user needs to cool the indoor air, the second fan wheel 30 in the connecting space 14 rotates. The air intake space 13 is connected to the connecting space 14, so as the second fan wheel 30 rotates, it can guide the air, allowing the indoor air to enter the air intake space 13 through the opening 5. Before entering the air intake space 13, the air will pass through the filter plate 9, which filters impurities in the air and retains the fibrous impurities in the air. Under the action of the second fan wheel 30, the air in the air intake space 13 will enter the connecting space 14.

[0045] Air in the connecting space 14 can be directed into the cold space 12, and the air will be output through the evaporator 31. Refrigerant flows in the pipe 22. When the refrigerant passes through the evaporator 31, it will heat up and form a gaseous state. The refrigerant will absorb heat during the heating process. After the air absorbs heat, it will cool down and become cold air. Then, the indoor air is made into cold air and output through the lower outlet 3. Changing the angle of the louvered fan 6 at the lower outlet 3 can change the direction of the cold air.

[0046] When cooling the room, the louvers 6 at the upper outlet 2 are closed to form a panel, thus sealing the partition 8 at the upper outlet 2. At the same time, the louvers 6 at the rear outlet 7 are opened, so that the partition 8 at the rear outlet 7 is in an open state. The refrigerant will liquefy after releasing heat through the condenser 21. The liquefied refrigerant continues to be transported forward and passes through the evaporator 31. The refrigerant in the evaporator 31 will vaporize to form a gas. The liquefaction process will release heat, making the surrounding air hot. The first fan wheel 34 can rotate and blow towards the condenser 21, and output heat dissipation from the rear outlet 7. The refrigerant circulates once and enters the compressor 24. In the compressor 24, the refrigerant is in a high-temperature and high-pressure gaseous state. Then it enters the condenser 21, undergoes the liquefaction process and becomes liquid. Then, when it passes through the evaporator 31, it will evaporate and absorb heat, and become gaseous refrigerant again. Finally, it will return to the compressor 24, forming a complete refrigeration cycle.

[0047] When indoor heating is required, the louvers 6 at the lower outlet 3 are closed to seal the partition 8. At this time, the second impeller 30 does not work. The refrigerant still passes through the evaporator 31 first, and then is sent to the condenser 21 to condense and release heat, making the surrounding air hot. The louvers 6 at the rear outlet 7 are opened, and the louvers 6 at the upper outlet 2 are also opened to open the partition 8. As the first impeller 34 rotates, the air enters the hot space 10 through the rear outlet 7 and is heated by the condenser 21 to form hot air. Finally, it is output through the upper outlet 2. At this time, the output is hot air to heat the indoor environment. The second impeller 30 does not work and does not guide the air. It is connected to the outside through the air intake space 13. The first impeller 34 is a turbine fan. The driving device for the turbine fan is a servo motor. The forward and reverse rotation of the turbine fan will change the air direction.

[0048] When indoor air dehumidification is required, close the louvered fan 6 at the rear outlet 7 to seal it, and open the louvered fans 6 at the upper outlet 2 and the lower outlet 3. The second fan wheel 30 rotates to draw in outside air. When the air passes through the evaporator 31, it will absorb heat and its temperature will drop. Correspondingly, the moisture in the air will condense into liquid and flow down along the surface of the evaporator 31. The water tank 15 below collects the liquid, and the water will be collected along the slope into the collection tank 33 at one end, and finally discharged through the water pipe 16.

[0049] As the air temperature drops during dehumidification, the refrigerant heats the surrounding air as it passes through the condenser 21. The first fan 34 is activated to guide the hot air, allowing it to be output through the upper outlet 2. At this time, the cold and hot air will mix as they are output from the same side, and the hot air will heat the cold air, thus preventing the temperature from dropping during dehumidification.

[0050] This device combines the dehumidification process with the cooling and heating process, and during dehumidification, there is no need for an additional resistance wire to reheat the cold air, which can effectively save energy.

[0051] The above description is only a preferred embodiment of the present invention. It should be noted that for those skilled in the art, several improvements and modifications can be made without departing from the principle of the present invention, and these improvements and modifications should also be considered within the scope of protection of the present invention.
