Description

Technical Field

[0001] This utility model relates to the technical field of compressors for dehumidifiers, specifically a low-power dehumidifier compressor unit. Background Technology

[0002] In modern living and industrial environments, dehumidification equipment has become a key device for regulating air humidity and improving environmental comfort. Among them, compressor-type dehumidifiers are widely used due to their high dehumidification capacity. Their core working principle is based on the reverse Carnot cycle. A compressor drives the refrigerant to circulate within the system, using an evaporator as a cold source to cool the intake of high-humidity air. When the air temperature drops below the dew point, the moisture condenses and separates in liquid form, thus achieving dehumidification. The treated dry air is then released back into the environment after being cooled by the condenser.

[0003] However, existing compressor-type dehumidifiers generally suffer from excessive power consumption, a deficiency that severely restricts their energy efficiency and the expansion of their application scenarios. Ultimately, the energy loss of the compressor itself is the core factor leading to excessive overall power consumption. From a thermodynamic perspective, during gas compression, mechanical work is inevitably converted into the gas's internal energy, manifested as a significant increase in gas temperature after compression. Gas molecules at higher temperatures have greater kinetic energy and higher internal energy, requiring stronger intermolecular forces to be overcome during subsequent compression. This results in a substantial increase in actual compression work, leading to significant energy waste compared to ideal isothermal compression.

[0004] In addition, a large amount of waste heat generated during the compression process is not effectively utilized, but instead needs to be released into the environment through a heat dissipation device, which not only wastes energy, but may also have an unnecessary impact on the surrounding temperature. Utility Model Content

[0005] To address the shortcomings of existing technologies, this utility model provides a low-power dehumidifier compressor unit to solve the problems of high energy consumption and energy waste in existing compressor dehumidifiers mentioned in the background.

[0008] A two-stage compression cylinder, wherein the two-stage compression cylinder is a cylindrical compressor cylinder, and an air outlet pipe is provided on the two-stage compression cylinder;

[0009] A switchable cascade tube is disposed between the first-stage compression cylinder and the second-stage compression cylinder, and the switchable cascade tube contains two different cascade paths;

[0010] The first cascade pipeline is a set of cascade paths. The first cascade pipeline is located on one side of the first-stage compression cylinder and the second-stage compression cylinder, and the first-stage compression cylinder and the second-stage compression cylinder can be sealed and connected through the first cascade pipeline.

[0011] The second cascade pipeline is another set of cascade paths. The second cascade pipeline is located on the side of the first cascade pipeline away from the first-stage compression cylinder, and the first-stage compression cylinder and the second-stage compression cylinder can be sealed and connected through the second cascade pipeline.

[0012] Preferably, the cross-sectional area of ​​the secondary compression cylinder is smaller than that of the primary compression cylinder.

[0013] Preferably, the switchable cascade includes an output pipe and a receiving pipe. The output pipe is disposed on the first-stage compression cylinder, and the receiving pipe is disposed on the second-stage compression cylinder. Both the output pipe and the receiving pipe are provided with tee connectors at their ends. The two different cascade paths are sealed to the output pipe and the receiving pipe through the two sets of tee connectors, and the two different cascade paths are in parallel.

[0019] Compared with the prior art, this utility model provides a low-power dehumidifier compressor unit, which has the following beneficial effects:

[0020] This low-power dehumidifier compressor unit is equipped with a primary compression cylinder, a secondary compression cylinder, and a switchable inductor. Based on a two-stage compressor, the device uses a unique switchable inductor to adjust the connection between the two sets of compression cylinders. Dehumidifiers using this device do not require a separate heating device.

[0025] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0026] Please see Figure 1-3 This utility model provides a technical solution:

[0027] A low-power dehumidifier compressor unit includes:

[0028] The first-stage compression cylinder 1 is a cylindrical compressor cylinder, and an air inlet pipe 2 is provided on the first-stage compression cylinder 1.

[0029] The secondary compression cylinder 3 is a cylindrical compressor cylinder, and an exhaust pipe 4 is provided on the secondary compression cylinder 3. A piston is also provided inside the compression cylinder, and the piston performs a reciprocating stroke motion under the drive of the compressor core. This utility model does not limit the specific cylinder piston and compressor core model, and those commonly used by those skilled in the art are applicable to this utility model.

[0030] The switchable cascade tube 5 is located between the first-stage compression cylinder 1 and the second-stage compression cylinder 3. The switchable cascade tube 5 contains two different cascade paths.

[0031] The first-stage pipeline 6 is a series of cascade paths. The first-stage pipeline 6 is located on one side of the first-stage compression cylinder 1 and the second-stage compression cylinder 3, and the first-stage compression cylinder 1 and the second-stage compression cylinder 3 can be sealed and connected through the first-stage pipeline 6.

[0032] The second stage pipeline 7 is another set of stage paths. The second stage pipeline 7 is located on the side of the first stage pipeline 6 away from the first stage compression cylinder 1, and the first stage compression cylinder 1 and the second stage compression cylinder 3 can be sealed and connected through the second stage pipeline 7.

[0033] Furthermore, the cross-sectional area of ​​the secondary compression cylinder 3 is smaller than that of the primary compression cylinder 1. Because the volume of gas decreases after compression, the smaller cross-sectional area of ​​the secondary compression cylinder 3 is beneficial for improving compression efficiency.

[0034] Furthermore, the switchable cascade 5 includes an output pipe 8 and a receiving pipe 9. The output pipe 8 is installed on the first-stage compression cylinder 1, and the receiving pipe 9 is installed on the second-stage compression cylinder 3. Both the output pipe 8 and the receiving pipe 9 are equipped with T-joints 10 at their ends. The two different cascade paths are sealed to the output pipe 8 and the receiving pipe 9 through the two sets of T-joints 10, and the two different cascade paths are in parallel. Only one of the two different cascade paths is always connected, allowing the first-stage compressed gas to be input into the second-stage compression cylinder 3 for compression.

[0035] Furthermore, the first-stage pipeline 6 includes a straight pipe 11, the two ends of which are sealed to two sets of tee connectors 10. The straight pipe 11 is connected to the output pipeline 8 and the receiving pipeline 9 through the two sets of tee connectors 10. The first-stage pipeline 6 is suitable for summer, does not cool the first-stage compressed gas, and will not cause the gas output by the dehumidifier to heat up.

[0036] Furthermore, a first electrically controlled pipeline valve 12 is installed near the receiving pipeline 9 on the straight pipe 11. The first electrically controlled pipeline valve 12 and the second electrically controlled pipeline valve 16 are used to control the pipeline connection, facilitating the switching of different cascade paths.

[0037] Furthermore, the second-stage pipeline 7 includes a first connecting pipe 13, a cooling pipe 14, and a second connecting pipe 15. One end of the first connecting pipe 13 is sealed to the output pipe 8 via a tee connector 10, and one end of the second connecting pipe 15 is sealed to the receiving pipe 9 via a tee connector 10. The cooling pipe 14 is located between the first connecting pipe 13 and the second connecting pipe 15, with the downstream end of the first connecting pipe 13 and the upstream end of the second connecting pipe 15 both sealed to the cooling pipe 14. The second-stage pipeline 7 is suitable for winter use. The first-stage compressed gas exchanges heat with the dehumidifier's output gas at the cooling pipe 14, significantly reducing the temperature of the first-stage compressed gas. After cooling, the internal energy of the first-stage compressed gas decreases significantly, making it easier to compress and greatly reducing energy consumption, thus saving energy. Meanwhile, the dehumidifier's output gas will warm up, making people feel more comfortable, eliminating the need for a special heating device for winter and significantly saving energy.

[0038] Furthermore, a second electrically controlled pipeline valve 16 is provided on the first connecting pipe 13.

[0039] Furthermore, the cooling pipe 14 is a spiral structure made of copper and is fixedly installed at the air outlet of the dehumidifier. Copper has excellent thermal conductivity, which facilitates heat exchange between the dehumidifier's output gas and the primary compressed gas. The spiral design also makes it easy to install the cooling pipe 14 at the air outlet and increases the heat exchange area. Example

[0040] Suitable for summer, the first electrically controlled pipeline valve 12 is opened while the second electrically controlled pipeline valve 16 is closed. At this time, the first-stage compressed gas in the first-stage compression cylinder 1 is transported to the second-stage compression cylinder 3 through the first-stage pipeline 6 for second-stage compression, providing the operating basis for the staged compressor refrigeration. The high-humidity gas drawn in by the dehumidifier is cooled at the condenser, and the moisture in it undergoes a phase change and is separated. The moisture content in the output gas is greatly reduced, and the temperature of the output gas is lower, making it more comfortable for people in summer. Example

[0041] Suitable for winter, the first electrically controlled pipeline valve 12 is closed while the second electrically controlled pipeline valve 16 is opened. At this time, the first-stage compressed gas in the first-stage compression cylinder 1 is transported to the second-stage compression cylinder 3 through the second-stage pipeline 7 for second-stage compression. When the first-stage compressed gas passes through the cooling pipeline 14, it exchanges heat with the dehumidifier output gas to cool down. The high-humidity gas drawn in by the dehumidifier is cooled at the condenser, and the moisture in it undergoes a phase change and is released. The low-humidity, low-temperature gas output exchanges heat with the first-stage compressed gas at the cooling pipeline 14, and the temperature of the output gas will rise, making people feel more comfortable in winter.

[0048] First-stage pipeline 6: Composed of straight pipes 11, both ends are sealed to the output pipeline 8 and the receiving pipeline 9 through tee connectors 10. It is a series of connecting paths between the first-stage compression cylinder 1 and the second-stage compression cylinder 3.

[0049] The second-stage pipeline 7 includes the first connecting pipe 13, the cooling pipe 14, and the second connecting pipe 15. It is sealed to the output pipe 8 and the receiving pipe 9 through the tee connector 10. It is another set of stage paths connecting the first-stage compression cylinder 1 and the second-stage compression cylinder 3.

[0050] Output pipe 8: It is installed on the first-stage compression cylinder 1, and has a three-way connector 10 at the end, which is used to output the compressed gas from the first stage to the cascade pipeline.

[0051] Receiving pipe 9: It is installed on the secondary compression cylinder 3 and has a three-way connector 10 at the end, which is used to receive gas from the cascade pipeline and deliver it to the secondary compression cylinder 3.

[0052] T-connector 10: respectively installed at the ends of output pipe 8 and receiving pipe 9, used to connect output pipe 8, receiving pipe 9 and two sets of cascade paths to achieve a sealed connection of the pipes;

[0053] Straight pipe 11: It is a component of the first-stage pipeline 6, and its two ends are sealed to the tee connector 10. It is used to connect the output pipeline 8 and the receiving pipeline 9.

[0054] First electrically controlled pipeline valve 12: Located near the receiving pipeline 9 on the straight pipe 11, used to control the on / off state of the first cascade pipeline 6;

[0055] First connecting pipe 13: It is a component of the second stage pipeline 7. One end is sealed to the output pipeline 8 through the tee connector 10, and the other end is connected to the cooling pipeline 14.

[0056] Cooling pipe 14: a spiral structure made of copper metal, fixed to the dehumidifier outlet, with the first connecting pipe 13 and the second connecting pipe 15 at both ends, for heat exchange with the dehumidifier output gas;

[0057] The second connecting pipe 15 is a component of the second-stage pipeline 7. One end is connected to the cooling pipe 14, and the other end is sealed to the receiving pipe 9 through the tee connector 10.

[0058] Second electrically controlled pipeline valve 16: installed on the first connecting pipe 13, used to control the on / off state of the second cascade pipeline 7.

[0059] Working Principle: This low-power dehumidifier uses a compressor unit based on the two-stage compression principle, achieving efficient energy utilization under different seasonal conditions through a switchable cascade tube. Its core workflow is as follows: High-humidity air is processed before entering the system, while refrigerant gas enters the first-stage compression cylinder 1 through the inlet pipe 2 for initial compression. The resulting compressed gas is then transported to the second-stage compression cylinder 3 via the switchable cascade tube 5 for secondary compression, and finally discharged through the outlet pipe 4. This entire process, in conjunction with the condenser, achieves air dehumidification and energy recycling.

[0060] The switchable cascade 5 connects the first cascade 6 and the second cascade 7 in parallel via the output pipe 8, the receiving pipe 9, and two sets of tee connectors 10. The alternating opening and closing of the first electrically controlled pipe valve 12 and the second electrically controlled pipe valve 16 ensures that only one of the two paths is always operational. The second-stage compression cylinder 3 has a smaller cross-sectional area than the first-stage compression cylinder 1, accommodating volume changes after gas compression and improving compression efficiency.

[0061] In summer operation (Example 1), the first electrically controlled pipeline valve 12 is open and the second electrically controlled pipeline valve 16 is closed. The primary compressed gas enters the secondary compression cylinder 3 directly through the straight pipe 11 of the first cascade pipeline 6. At this time, the system does not perform additional heat exchange, and the primary compressed gas maintains its original temperature before entering the secondary compression stage. In conjunction with the dehumidifier's working process, the high-humidity air is cooled and dehydrated at the condenser, resulting in a lower temperature output dry air that meets the human body's need for a cool environment in summer.

[0062] In winter operation (Example 2), the valve status is switched so that the first electrically controlled pipeline valve 12 is closed and the second electrically controlled pipeline valve 16 is open, and the primary compressed gas is transported via the second cascade pipeline 7. The gas sequentially enters the cooling pipeline 14 through the first connecting pipe 13. This pipeline adopts a spiral structure made of high thermal conductivity copper and is installed at the air outlet of the dehumidifier to enhance heat exchange efficiency by increasing the heat exchange area. In this stage, the primary compressed gas and the low-temperature dry air output by the dehumidifier complete heat exchange: the high-temperature compressed gas releases heat and its temperature drops significantly, greatly reducing its internal energy, thus saving a lot of energy for the subsequent secondary compression; while the low-temperature dry air absorbs heat and its temperature rises, meeting the winter heating needs without the need for an additional heating device, realizing the cascade utilization of energy with less energy waste and low energy consumption.
