Abstract
Description
Technical Field
[0001] This utility model relates to the technical field of dehumidifiers, and in particular to the structure of a two-way flow dehumidifier. Background Technology
[0002] In numerous fields, including daily life, industrial production, and business operations, air humidity and quality have a crucial impact on people's health, productivity, and product quality. Appropriate air humidity can improve human comfort and prevent a range of health problems caused by excessively dry or humid air, such as dry skin and respiratory illnesses. At the same time, good air quality can effectively reduce pollutants such as dust, pollen, and bacteria in the air, lowering the risk of allergic reactions and disease transmission, and creating a healthy and safe living and working environment for people.
[0003] Traditional dehumidifiers and air handling units have different functionalities. Traditional dehumidifiers primarily focus on reducing air humidity, making their function relatively simple. In scenarios where both fresh air and humidity regulation are needed, such as basements and newly built houses, traditional dehumidifiers cannot introduce fresh air, leading to poor indoor air circulation and problems like stuffiness and odors. On the other hand, air handling units that do introduce fresh air often lack effective dehumidification capabilities, failing to meet users' humidity control needs. This functional limitation makes traditional equipment difficult to adapt to the complex and diverse air handling requirements of different scenarios. Utility Model Content

[0028] Figure 1 This is a structural diagram of a bidirectional flow dehumidifier according to the present invention. Figure 2 This is a side sectional view of the structure of a bidirectional flow dehumidifier according to this utility model, as shown below. Figure 1-2 The diagram illustrates the structure of a preferred embodiment of a bidirectional flow dehumidifier, comprising: a housing 1 and a dehumidification module 3 and a total heat exchanger 5 disposed within the housing 1. One side of the housing 1 has an exhaust air inlet 11 and a fresh air exhaust outlet, and the other side has an exhaust air outlet 13 and a fresh air inlet 14. The housing 1 also includes a fresh air duct 15 connecting the fresh air inlet 14 and the fresh air outlet 12, and an exhaust duct 16 connecting the exhaust air inlet 11 and the exhaust air outlet 13. The dehumidification module 3 is disposed within the fresh air duct 15 between the fresh air outlet 12 and the total heat exchanger 5. The exhaust duct 16 includes an air collection section 161 and an exhaust section 162, and the exhaust air inlet 16... The air inlet 11, the air collection section 161, the air exhaust section 162, and the air exhaust outlet 13 are connected in sequence, and the air exhaust section 162 is intersected with the fresh air duct 15. A total heat exchanger 5 is installed at the intersection of the air exhaust section 162 and the fresh air duct 15. The air collection section 161 is provided with a circulation channel 18 connecting the fresh air duct 15 located between the dehumidification module 3 and the heat exchanger, and a bypass channel 17 connecting the air exhaust outlet 13. Air valves 8 are installed in the circulation channel 18, the bypass channel 17, and the air exhaust section 162 located between the air collection section 161 and the total heat exchanger 5, for opening or blocking the circulation channel 18 / bypass channel 17 / air exhaust section 162.
[0029] The specific operation of this embodiment is as follows:
[0030] Fresh air dehumidification mode: Fresh air enters the fresh air channel 15 through the fresh air inlet 14 and passes through the total heat exchanger 5 and the dehumidification module 3 in sequence to achieve the functions of fresh air dehumidification and heat exchange;
[0031] Exhaust mode: Exhaust air enters the exhaust channel 16 through the exhaust air inlet 11. The air valves 8 in the bypass channel 17 and the circulation channel 18 are closed. The exhaust air enters the exhaust section 162 through the air collection section 161 and is discharged towards the exhaust air outlet 13 after passing through the total heat exchanger 5, thus realizing the functions of exhaust and heat exchange.
[0032] Internal circulation dehumidification mode: The air valve 8 in the exhaust section 162 and the bypass channel 17 is closed. The exhaust air enters the fresh air channel 15 through the air collection section 161 and the circulation channel 18, and is discharged through the dehumidification module 3 and the fresh air outlet 12 in sequence, realizing the internal circulation and dehumidification functions.
[0033] Bypass mode: The air valves 8 in the exhaust section 162 and the circulation channel 18 are closed, and the exhaust air passes through the collection section 161 and the bypass channel 17 in sequence, and is discharged from the exhaust outlet 13.
[0034] Specifically, the fresh air inlet 14 can also be equipped with a damper 8, which is closed in the internal circulation dehumidification mode.
[0035] The multiple operating modes in this application meet the usage needs in different scenarios. The fresh air dehumidification mode is suitable for situations where fresh air needs to be introduced and dehumidified; the exhaust mode is used to exhaust indoor stale air and perform heat exchange; the internal circulation dehumidification mode can circulate and dehumidify indoor air when fresh air does not need to be introduced; and the bypass mode provides a simple exhaust path, improving the practicality and energy efficiency of the equipment.
[0036] Specifically, the aforementioned channels are formed by internal partitions of the outer casing 1.
[0037] Furthermore, as a preferred embodiment, a sliding plate 2 is provided inside the fresh air duct 15. The sliding plate 2 can slide along the width direction of the outer shell 1, and the dehumidification module 3 is disposed on the sliding plate 2. The side of the outer shell 1 has an inspection door that can be opened to access the interior of the outer shell 1. When disassembling or assembling the dehumidification module 3, the inspection door can be opened, and the sliding plate 2 can be pulled outward to remove the dehumidification module 3 from the outer shell 1 for disassembly, assembly, maintenance, and repair.
[0038] In this embodiment, the sliding plate 2 allows the position of the dehumidification module 3 to be adjusted, which facilitates the installation, maintenance and repair of the equipment, and also provides convenience for possible future upgrades and modifications.
[0039] Specifically, the dehumidification module 3 may include a compressor, a condenser, and an evaporator. The compressor's exhaust port is directly connected to the condenser's inlet via a copper pipe. When the compressor is running, it compresses the low-temperature, low-pressure gaseous refrigerant into a high-temperature, high-pressure gaseous refrigerant, which is then transported to the condenser via the copper pipe. The condenser's liquid outlet is connected to a throttling device (such as a capillary tube or expansion valve) via a copper pipe, and the other end of the throttling device is connected to the evaporator's inlet via a copper pipe. The high-temperature, high-pressure gaseous refrigerant releases heat to the external environment in the condenser, condensing into a high-pressure liquid refrigerant. This liquid refrigerant then passes through the throttling device to reduce its pressure, becoming a low-temperature, low-pressure liquid refrigerant, which finally enters the evaporator. The evaporator's outlet is connected back to the compressor's suction port via a copper pipe. The low-temperature, low-pressure liquid refrigerant absorbs heat from the surrounding environment in the evaporator and evaporates into a low-temperature, low-pressure gaseous refrigerant, which is then drawn back by the compressor for recompression, and this cycle repeats continuously.
[0040] The principle is as follows: The compressor compresses the low-temperature, low-pressure refrigerant gas into a high-temperature, high-pressure gas, which is then sent to the condenser. In the condenser, the refrigerant gas releases heat and condenses into a high-pressure liquid. After being throttled by the throttling device, the high-pressure liquid becomes a low-temperature, low-pressure liquid and enters the evaporator. In the evaporator, the low-temperature, low-pressure liquid refrigerant absorbs heat from the surrounding air and evaporates into gas, thus lowering the air temperature. When the air temperature drops below the dew point temperature, the water vapor in the air condenses into water droplets, thereby achieving the purpose of dehumidification.
[0041] Furthermore, as a preferred embodiment, the access door is detachably connected to the housing 1 via screws. The access door facilitates maintenance personnel opening the housing 1 to inspect and repair internal components, improving equipment maintainability and reducing maintenance time and costs.
[0042] Furthermore, as a preferred embodiment, the fresh air outlet 12 and the fresh air duct 15 are connected through a first chamber, which contains an intake fan 6. The arrangement of the first chamber and the intake fan 6 can provide stable fresh air and circulating air intake power, ensuring that fresh air and circulating air can smoothly enter the fresh air duct 15 and be dehumidified before being sent into the room, thereby improving the stability and efficiency of the fresh air and circulating air supply.
[0043] Furthermore, as a preferred embodiment, the exhaust section 162 and the exhaust outlet 13 are connected by a second chamber, in which an exhaust fan 7 is installed. The second chamber and the exhaust fan 7 provide stable exhaust power, ensuring that indoor polluted air can be smoothly discharged outdoors, thus improving the exhaust effect and efficiency.
[0044] More preferably, in this application, the bottom of the first chamber / second chamber has several positioning grooves, and the air inlet fan 6 / exhaust fan 7 has several pins, which are respectively positioned and inserted into the several positioning grooves.
[0045] Furthermore, as a preferred embodiment, the bypass channel 17 is connected to the exhaust outlet 13 via the second chamber. This connection method allows the exhaust air in the bypass channel 17 to be smoothly discharged outdoors with the help of the exhaust fan 7 in the second chamber, simplifying the equipment structure and improving the smoothness of exhaust.
[0046] Furthermore, as a preferred embodiment, a high-efficiency filter 4 is also installed in the fresh air duct 15 between the dehumidification module 3 and the total heat exchanger 5. The high-efficiency filter 4 can filter impurities such as dust and pollen in the fresh air, improve the quality of the fresh air introduced into the room, and protect the health of the residents.
[0047] Furthermore, as a preferred embodiment, the air valve 8 is an electric valve.
[0048] Specifically, the air valve 8 can be a valve plate, which is rotated by a motor to block or open the internal passages of the bypass channel 17 / circulation channel 18 / exhaust section 162. More preferably, in order to improve the sealing performance of the valve plate, a sealing rubber ring can be installed around the valve plate.
[0049] Furthermore, as a preferred embodiment, the air collection section 161 is arranged along the length of the outer casing 1 and located below the dehumidification module 3. This arrangement makes the internal structure of the equipment more compact and reasonable, makes full use of the space inside the outer casing 1, and is conducive to the uniform distribution and flow of airflow, thereby improving the overall performance of the equipment.
[0050] Furthermore, as a preferred embodiment, a negative ion generator 9 is also installed in the fresh air duct 15 located between the fresh air outlet 12 and the dehumidification module 3. This releases negative ions to improve air quality.
[0051] The above description is only a preferred embodiment of the present utility model and does not limit the implementation method and protection scope of the present utility model. Those skilled in the art should realize that all solutions obtained by equivalent substitutions and obvious changes made based on the description and illustrations of the present utility model should be included within the protection scope of the present utility model.
