Abstract
Description
Technical Field
[0001] This invention relates to the field of air conditioning equipment technology, and in particular to a solution regeneration device for solution-type air conditioning and a solution-type air conditioner. Background Technology
[0002] In existing technologies, solution-based air conditioning is a new type of energy-saving and environmentally friendly air conditioning. Solution-based air conditioning can absorb moisture from the air through a solution, reducing air humidity and thus achieving independent heat and humidity control.
[0003] In a solution-based air conditioner, the dehumidification process is cyclical, primarily achieved through the coordinated operation of a solution dehumidification module and a solution regeneration module. The solution regeneration process in a solution-based air conditioner involves the solution absorbing heat from a heat source, causing the solution temperature to rise. This raises the partial pressure of water vapor in the solution to be higher than that in the ambient air. Mass transfer occurs between the solution and the ambient air, causing moisture to migrate from the solution to the ambient air, thus concentrating the solution.
[0004] Currently, solution-based air conditioners typically use a mixture of lithium chloride and calcium chloride as the desiccant solution. However, to achieve optimal desiccant concentration, the solution needs to be heated to 70°C to 80°C to complete the regeneration process. Unfortunately, due to space constraints and rated power limitations, existing solution-based air conditioners generally place the regeneration module in the outdoor unit, with a heater installed in the module's collection tank. The solution is heated by both the heater and the condenser. Consequently, the energy consumed in solution regeneration exceeds the energy savings achieved through solution dehumidification, failing to achieve energy-saving and environmentally friendly effects. Therefore, a technical solution that can reduce the solution regeneration temperature to save energy is urgently needed. Summary of the Invention

[0027] In this invention, the full English name of Celdek packing is "Celdek fill media" or "Celdek packing", which is specifically used to improve heat exchange efficiency and enhance gas-liquid contact effect.
[0028] In existing technologies, solution-based air conditioning is a new type of energy-saving and environmentally friendly air conditioning. Solution-based air conditioning can absorb moisture from the air through a solution, reducing air humidity and thus achieving independent heat and humidity control.
[0029] In a solution-based air conditioner, the dehumidification process is cyclical, primarily achieved through the coordinated operation of a solution dehumidification module and a solution regeneration module. The solution regeneration process in a solution-based air conditioner involves the solution absorbing heat from a heat source, causing the solution temperature to rise. This raises the partial pressure of water vapor in the solution to be higher than that in the ambient air. Mass transfer occurs between the solution and the ambient air, causing moisture to migrate from the solution to the ambient air, thus concentrating the solution.
[0030] Currently, solution-based air conditioners typically use a mixture of lithium chloride and calcium chloride as the desiccant solution. However, for a solution to achieve good desiccant absorption efficiency, it needs to be heated to 70°C to 80°C to complete the regeneration process. But due to space constraints and rated power limitations, solution-based air conditioners generally place the solution regeneration module in the outdoor unit, with a heater installed in the liquid collection tank 20 of the module. The solution is heated jointly by the heater and the condenser 100. Therefore, the energy consumed by solution regeneration exceeds the energy savings of using solution dehumidification, failing to achieve the desired energy-saving and environmentally friendly effect.
[0031] To reduce the energy consumption required for the solution regeneration process and improve the energy-saving performance of solution-based air conditioners, this invention provides a solution regeneration device for solution-based air conditioners.
[0032] like Figure 1 and Figure 2 As shown, the solution regeneration device includes a support structure 10, a spray component 40, a liquid collection tank 20, a Celdek packing material 30, and an ultrasonic excitation module 50.
[0033] Specifically, the support structure 10 is located on the side of the condenser 100 inside the outdoor unit. The support structure 10 has a cavity 11 inside. The spray element 40 is located at the top of the cavity 11. The liquid collection tank 20 is located at the bottom of the cavity 11. Celdek packing 30 is located between the spray element 40 and the liquid collection tank 20 to increase the contact surface between the solution and the air.
[0034] The ultrasonic excitation module 50 is installed in the liquid collection tank 20 and is used to convert the power frequency of the current into a high frequency for ultrasonic oscillation.
[0035] In addition, the solution-based air conditioner includes a solution dehumidification device, a solution regeneration device, a compressor, a throttling valve, a circulating pump, and a condenser 100. The solution dehumidification device is installed in the indoor unit of the air conditioner. Indoor air circulates in and out of the indoor unit of the air conditioner, and the solution dehumidification device removes the moisture in the air to complete the dehumidification operation.
[0036] The solution dehumidification unit, solution regeneration unit, and circulation pump are connected in series via pipelines to circulate solutions such as lithium chloride and calcium chloride, which can effectively absorb moisture. After the solution has fully absorbed moisture in the solution dehumidification unit, it flows into the solution regeneration unit. In the solution regeneration unit, the solution is evenly sprayed onto the Celdek packing 30 through the spray element 40.
[0037] The Celdek packing 30 is made of a special polyvinyl chloride (PVC) material, which has good corrosion resistance and mechanical strength. The Celdek packing 30 can be designed in a corrugated or honeycomb structure, thereby increasing the contact area between the solution and air as the solution flows through, significantly improving heat exchange efficiency. Thus, by placing the solution regeneration device on the air outlet side of the condenser 100, the hot air blown from the condenser 100 can be fully utilized to heat the solution.
[0038] After passing through the Celdek packing 30, the solution collects in the collection tank 20. Then, the ultrasonic excitation module 50 agitates the solution in the collection tank 20, lowering the regeneration temperature and promoting efficient evaporation of water, thus improving regeneration efficiency. Simultaneously, the ultrasonic excitation module 50 also ultrasonically disturbs the heat and mass transfer during the spraying process, promoting water dissolution into the air as the solution flows through the Celdek packing 30.
[0039] In this embodiment, the solution regeneration device can generate cavitation effect by vibrating the solution through the ultrasonic excitation module 50. At the same time, the ultrasonic excitation module 50 can ultrasonically disturb the heat and mass transfer during the spraying process, reduce the regeneration temperature, promote the efficient evaporation of water vapor in the solution, improve the regeneration efficiency of the solution, and thus greatly reduce the energy consumption required for the solution regeneration process, making the solution air conditioner more energy-efficient and environmentally friendly.
[0040] Based on the above embodiments, another embodiment of the present invention introduces a solution regeneration device for solution-type air conditioning.
[0041] like Figure 2As shown, the ultrasonic excitation module 50 is disposed within the liquid collection tank 20 and is used to oscillate the solution to generate a cavitation effect. The cavitation effect refers to the series of compression and rarefaction cycles that occur when ultrasonic waves propagate through a liquid. During the rarefaction phase, the local pressure of the liquid decreases below the vapor pressure, leading to the formation of tiny bubbles or cavities. During the compression phase, these bubbles rapidly collapse, releasing enormous energy. This results in a cavitation effect in the liquid, generating high temperatures and pressures at the moment of cavitation, which can be used to promote chemical reactions, accelerate the dissolution process, or improve cleaning efficiency.
[0042] Alternatively, the ultrasonic excitation module 50 is fixedly connected to the support structure 10 for airflow within the oscillation cavity 11.
[0043] Specifically, the ultrasonic excitation module 50 is commonly referred to as an ultrasonic power supply box, ultrasonic generator, or ultrasonic power source. The ultrasonic excitation module 50 converts household AC power (220V, 50Hz or 60Hz) into a high-frequency AC signal that matches the ultrasonic transducer. The amplification circuit in the ultrasonic excitation module 50 can be a linear amplification circuit or a switching power supply circuit. Considering conversion efficiency, high-power ultrasonic excitation modules 50 generally use a switching power supply circuit. Linear power supplies also have their specific application range; their advantage is that they do not require strict circuit matching and allow for continuous and rapid changes in operating frequency. Currently, in the ultrasonic industry, ultrasonic excitation modules 50 are mainly divided into self-excited and externally excited power supplies.
[0044] The working principle is as follows: A signal generator produces a signal of a specific frequency, which can be a sine wave or a pulse signal. This signal frequency is amplified by the ultrasonic excitation module 50. This specific frequency is the transducer frequency; commonly used ultrasonic frequencies in ultrasonic equipment are 20kHz, 28kHz, 40kHz, and 60kHz. Power amplifiers can come in various forms, such as Class A tube amplifiers, Class AB amplifiers, and Class A or Class B transistor amplifiers (both analog), including transistor switching amplifiers, with power typically ranging from 50W to 3000W.
[0045] In this invention, the ultrasonic excitation module 50 uses a minimum power of 30W-50W to generate airflow vibration, which promotes heat and mass transfer between the solution and the air.
[0046] Furthermore, the solution needs to be evenly sprayed onto the Celdek packing 30 within the solution regeneration device to promote heat and mass transfer between the solution and air. However, the spraying process can easily cause the solution to splash onto surrounding components, leading to corrosion of other metal parts in the outdoor unit and significantly reducing its service life. To address this problem, another embodiment of the present invention introduces a solution regeneration device capable of limiting the outward splashing of the solution.
[0047] The solution regeneration device also includes a shielding structure 60 for preventing solution splashing. The shielding structure 60 is attached to the inner surface of the cavity 11 and covers the collection tank 20, the Celdek packing 30 and the spray element 40.
[0048] The shielding structure 60 includes materials such as a filter screen 61 and louvers. Installing the filter screen 61 on the air inlet and outlet surfaces of the solution regeneration device facilitates airflow.
[0049] In addition, a water vapor outlet 12 is provided on the side of the support structure 10 away from the condenser 100. The water vapor outlet 12 is located on the vertical sidewall of the support structure 10. The condenser 100 is located on the other vertical sidewall of the support structure 10 opposite to the water vapor outlet 12. The Celdek packing 30 is attached to the water vapor outlet 12 on at least one side. The shielding structure 60 protrudes outward from the water vapor outlet 12 to form an arc-shaped curved surface.
[0050] The shielding structure 60 is configured with a filter screen 61 at least on the water vapor outlet 12 and on the side opposite to the water vapor outlet 12, for allowing air to flow smoothly from the condenser 100 to the Celdek packing 30 and out of the water vapor outlet 12.
[0051] Specifically, the solution regeneration device is located on the air outlet side of the condenser 100, using hot air flowing from the condenser 100 to heat the solution in the Celdek packing 30 area. Because the solution regeneration device is located on the side close to the condenser 100, solution may splash onto the condenser 100 due to the airflow. This solution can easily corrode the material of the condenser 100, causing environmental impact.
[0052] Furthermore, a filter screen 61 is provided on the inner side of the support structure 10 so that the filter screen 61 completely covers the liquid collection tank 20, the Celdek packing 30 and the spray component 40.
[0053] Preferably, the filter screen 61 is configured as an arc-shaped curved surface and is positioned over the outside of the Celdek filler 30.
[0054] More preferably, the shielding structure 60 at the water vapor outlet 12 is configured with a spherical curved surface using a filter screen 61. Furthermore, the mesh count of the filter screen 61 is not less than 80 meshes. The filter screen 61 is woven from stainless steel wire.
[0055] In this embodiment, a shielding structure 60 is provided around the solution regeneration device, which can not only prevent solution leakage and reduce solution loss, but also prevent the solution from corroding the material of the condenser 100, thereby improving the service life of the condenser 100 and reducing the impact on the environment.
[0056] Based on the above embodiments, another embodiment of the present invention introduces a solution regeneration device for solution-type air conditioning.
[0057] The solution regeneration device also includes a fan 200 for guiding air flow from the condenser 100 to the support structure 10. The shaft of the fan 200 is arranged perpendicular to the vertical side wall of the condenser 100. The support structure 10 is located between the fan blades 210 of the fan 200 and the condenser 100.
[0058] Furthermore, the shaft of the fan 200 is located below the support structure 10. The fan blades 210 of the fan 200 are located on the outside of the arc-shaped curved structure relative to the support structure 10.
[0059] Based on the above embodiments, another embodiment of the present invention introduces a solution regeneration device for solution-type air conditioning.
[0060] The solution regeneration device also includes a storage tank 80. The storage tank 80 is connected to the bottom of the collection tank 20 via a pipeline and is used to buffer the solution after water removal.
[0061] Based on the above embodiments, another embodiment of the present invention introduces a solution regeneration device for solution-type air conditioning.
[0062] The solution regeneration device also includes a heating structure 70 disposed in the collection tank 20 for heating the solution in the collection tank 20.
[0063] On the other hand, in another embodiment of the present invention, a solution-type air conditioner is described. The solution-type air conditioner is equipped with the solution regeneration device of any of the above embodiments.
[0064] A solution-based air conditioner includes a solution dehumidification device, a solution regeneration device, a compressor, a throttling valve, a circulating pump, and a condenser 100. The solution dehumidification device is installed in the indoor unit of the air conditioner. Indoor air circulates in and out of the indoor unit, and the solution dehumidification device removes moisture from the air to complete the dehumidification operation.
[0065] The solution dehumidification unit, solution regeneration unit, and circulation pump are connected in series via pipelines to circulate solutions such as lithium chloride and calcium chloride, which can effectively absorb moisture. After the solution has fully absorbed moisture in the solution dehumidification unit, it flows into the solution regeneration unit. In the solution regeneration unit, the solution is evenly sprayed onto the Celdek packing 30 through the spray element 40.
[0066] After passing through the Celdek packing 30, the solution collects in the collection tank 20. Then, the ultrasonic excitation module 50 agitates the solution in the collection tank 20, lowering the regeneration temperature and promoting efficient evaporation of water, thus improving regeneration efficiency. Simultaneously, the ultrasonic excitation module 50 also ultrasonically disturbs the heat and mass transfer during the spraying process, promoting water dissolution into the air as the solution flows through the Celdek packing 30.
[0067] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention, and not to limit them; although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some of the technical features; and these modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the spirit and scope of the technical solutions of the embodiments of the present invention.
