Description

Technical Field

[0001] The present application relates to the field of magnetic refrigeration technology, and in particular to an air conditioning system. Background Art

[0002] Magnetic refrigeration technology is a solid-state refrigeration method based on magnetocaloric effect. It uses environmentally friendly media such as water as heat transfer fluid. It has the characteristics of zero greenhouse effect, zero ozone layer damage, inherent high efficiency, low noise and low vibration. Compared with the low-temperature field, magnetic refrigeration has a broader application prospect in the room temperature range, such as household refrigerators, air conditioners, medical and health care, etc. Therefore, the research and development of room temperature magnetic refrigeration technology has received widespread attention from countries around the world in the past decade, and has achieved some world-renowned achievements.

[0003] According to the information disclosed in the magnetic refrigeration literature, the zero-load temperature span of the current magnetic refrigeration prototype can reach 40K, and the cooling power can reach 3kW at zero temperature span. For air conditioning, it is necessary to maintain the indoor air dry-bulb temperature at 27℃ and the wet-bulb temperature at 19℃ when the outdoor air temperature is 35℃. To ensure the dehumidification effect, the low-temperature heat exchanger temperature is generally required to be about 5℃. Considering the thermal resistance of the heat exchanger, the high-temperature heat exchanger temperature is not lower than 45℃, which means that the magnetic refrigeration system is required to achieve a cooling capacity of 2 to 10kW at a refrigeration temperature span of 40K. However, for the magnetic refrigeration system, a large temperature span will inevitably lead to a reduction in cooling capacity, and achieving a larger cooling capacity will lead to a reduction in the temperature span, making it difficult for the existing magnetic refrigeration system to meet the above-mentioned magnetic refrigeration requirements.

DETAILED DESCRIPTION

[0026] See also Figures 1 to 4 As shown, according to an embodiment of the present application, the air-conditioning system includes a magnetic refrigeration device and a solution dehumidification device, the magnetic refrigeration device includes a magnetic field generator, a magnetic cold storage device 210 and a cold end heat exchange component 310, the magnetic field generator includes a coil assembly and an iron core assembly 220, the coil assembly and the iron core assembly 220 cooperate to form a periodically changing magnetic field region, the magnetic cold storage device 210 is located in the magnetic field region, the solution dehumidification device includes a dehumidifier 300, and the cold end heat exchange component 310 exchanges heat with the dehumidification solution entering the dehumidifier 300 to cool the dehumidification solution before entering the dehumidifier 300.

[0027] The air conditioning system of the present application combines a magnetic refrigeration device and a solution dehumidification device together, so that the magnetic refrigeration device and the solution dehumidification device can form a synergy. The solution dehumidification device can be used to dehumidify indoor air, thereby eliminating the latent heat of the indoor air and reducing the temperature span of the magnetic refrigeration device during the air conditioning dehumidification process. The magnetic refrigeration device can provide cooling capacity for indoor refrigeration and can also provide the cooling capacity required for dehumidification by the dehumidifier 300. Since the temperature required for solution dehumidification is higher than the dehumidification temperature in the conventional condensation dehumidification process, it can achieve energy-saving effects. At the same time, it also reduces the condensation temperature required to be provided by the magnetic refrigeration device, so that the magnetic refrigeration system can realize air conditioning applications under a smaller temperature span, and reduces the technical indicators of the magnetic refrigeration device to meet the requirements of air conditioning use. With the cooperation of the solution dehumidification device, the magnetic refrigeration device can achieve a larger cooling capacity under a relatively small temperature span, thereby further promoting the practical application of magnetic refrigeration technology.

[0028] The magnetic refrigeration device of the air-conditioning system is a static magnetic refrigeration device, which uses a magnetic field generator formed by a coil assembly and an iron core assembly to generate a periodically changing magnetic field area. It does not require movement of the components of the magnetic field generator itself, nor does it require movement of the magnetic cold storage device. Therefore, the structure is simpler and the implementation cost is lower. It can effectively eliminate the noise caused by moving parts, achieve silent temperature and humidity adjustment, and provide a better user experience.

[0029] In addition, the introduction of the solution dehumidification device reduces or avoids the shortcomings of the magnetic refrigeration device such as condensation and bacterial growth, and improves the working performance of the magnetic refrigeration device.

[0030] After the dehumidified air 301 enters the dehumidifier 300 for dehumidification, it is blown out of the dehumidifier 300 and exchanges heat with the cold end heat exchange component 310 indoors or on the air flow path entering the dehumidifier 300 .

The air 301 to be dehumidified enters the dehumidifier 300 from the air inlet under the action of the indoor fan. After being dehumidified and cooled in the dehumidifier 300, the dehumidified air 302 obtains suitable temperature and humidity, flows out from the air outlet, and enters the room.

[0032] In another embodiment, after the dehumidified air enters the dehumidifier for dehumidification, it exchanges heat with the cold end heat exchange component.

The air circulation pump is used to provide circulation power for indoor air dehumidification. The dehumidified air 301 enters the dehumidifier 300 from the air inlet under the action of the air circulation pump. After being dehumidified in the dehumidifier 300, the dehumidified air 302 flows out from the air outlet and enters the room. Then the dehumidified air 302 exchanges heat with the cold end heat exchange component 310, and the indoor temperature regulation requirement is met under the action of the cold end heat exchange component 310. The cold end heat exchange component 310 in this embodiment is located outside the dehumidifier 300. On the one hand, it provides the dehumidification solution with the required cooling capacity for dehumidification, and on the other hand, it provides sufficient cooling capacity for indoor temperature regulation. Air dehumidification is performed through the solution dehumidification device, and air temperature regulation is performed through the cold end heat exchange component 310. Therefore, independent control of temperature and humidity can be achieved, which can effectively reduce the cooling capacity required in the temperature control process, achieve energy-saving effects, reduce the refrigeration load of the magnetic refrigeration device, and improve the working energy efficiency of the magnetic refrigeration device.

[0037] There are two coil assemblies, namely, a first coil assembly 211 and a second coil assembly 212. The first coil assembly 211 is wound around the first end of the core assembly 220, and the second coil assembly 212 is wound around the second end of the core assembly 220. The first coil assembly 211 and the second coil assembly 212 are arranged at an interval, and a working air gap is formed between the two.

When the magnetic cold storage device 210 is in the magnetization area, the first control valve is opened and the second control valve is closed, the heat dissipation circulation pipeline is in a connected state and can circulate normally, the first fluid pump 600 works, the refrigeration circulation pipeline is in a cut-off state and cannot circulate normally, and the second fluid pump 601 stops; when the magnetic cold storage device 210 is in the demagnetization area, the first control valve is closed and the second control valve is opened, the heat dissipation circulation pipeline is in a cut-off state and cannot circulate normally, the first fluid pump 600 stops, the refrigeration circulation pipeline is in a connected state and can circulate normally, and the second fluid pump 601 works.

[0041] The magnetic refrigeration device also includes a hot end heat exchange component 110. The regeneration solution 421 enters the regenerator 100 for regeneration after heat exchange in the hot end heat exchange component 110. Before entering the regenerator 100, the regeneration solution 421 first exchanges heat with the hot end heat exchange component 110, which can fully utilize the heat generated by the hot end of the magnetic cold storage device, further improve the regeneration efficiency of the regeneration solution 421, and avoid energy waste.

[0051] The air conditioning system of the present application, based on the static magnetic refrigeration technology, utilizes the heat generated by the electromagnetic coil to complete the regeneration of the regeneration solution 421. Based on the idea of ​​independent control of temperature and humidity, the cold end heat exchanger is modified to form a heat exchange structure for heat exchange with the dehumidification solution 411, and the hot end heat exchanger is modified to form a heat exchange structure for heat exchange with the regeneration solution 421. The static magnetic refrigeration device realizes the periodic change of the working air gap magnetic field of the electromagnet through the current change of the charging and demagnetization coil, thereby realizing the periodic magnetization and demagnetization of the magnetocaloric material in the magnetic cold storage area, and forming a certain temperature span. A low-temperature heat exchange fluid flows out at the outlet of the cold end of the magnetic cold storage, providing a cold source for the dehumidification solution 411, cooling and dehumidifying the air; at the same time, the heat generated in the coil assembly is used to provide a heat source for the regeneration solution 421 for solution regeneration.

[0052] See also Figure 1 As shown, in the first embodiment, the dehumidifier 300 is a spray tower structure or a spray tower structure, and the regenerator 100 is a spray tower structure or a spray tower structure.

[0053] The regeneration solution 421 pumped out from the first solution pump 410 is divided into two parts, one part exchanges heat with the coil assembly and then enters the regenerator 100 for regeneration, and the other part exchanges heat with the hot end heat exchange assembly 110 and then enters the regenerator 100 for regeneration.

[0054] The working process of the air conditioning system of this embodiment is as follows:

[0055] Heat exchange fluid working process: After the magnetic cold storage device 210 is magnetized, the first fluid pump 600 and the first control valve of the heat dissipation circulation loop work, and the high-temperature heat exchange fluid at the hot end outlet 243 of the heat exchange fluid of the magnetic refrigeration device passes through the hot end heat exchange component 110, and releases the magnetic heat at the hot end of the magnetic refrigeration device to the regeneration solution 421 to reduce the temperature. Driven by the first fluid pump 600, the heat exchange fluid enters the magnetic cold storage device 210 through the hot end inlet 244, absorbs heat, and then flows out from the hot end outlet 243 of the heat exchange fluid, forming a heat dissipation circulation loop.

[0056] After the magnetic cold storage device 210 is demagnetized, the second fluid pump 601 of the refrigeration cycle and the second control valve work, and the second fluid pump 601 drives the heat exchange fluid to enter the demagnetized magnetic cold storage device 210 for heat exchange. The cooled low-temperature heat exchange fluid passes through the cold end of the magnetic cold storage device 210, and passes through the cold end heat exchange component 310 from the cold end outlet 241 of the heat exchange fluid. After the cold is transferred to the dehumidification solution, the temperature rises, and enters the magnetic cold storage device 210 through the cold end inlet 242 of the heat exchange fluid. After absorbing the cold, it flows out from the cold end outlet 241 of the heat exchange fluid, forming an independent refrigeration cycle.

[0057] Dehumidification solution working process: the dehumidification solution 411 is driven by the second solution pump 420 from the liquid storage tank 400 to flow into the cold end heat exchange component 310, absorbs cold energy to become a low-temperature solution 412 and enters the dehumidifier 300, cools and dehumidifies the dehumidified air 301, and then becomes a dehumidified solution 413 and flows back to the liquid storage tank 400; the regeneration solution 421 is driven by the first solution pump 410 through the liquid storage tank 400 to flow into the regenerator 100. After regeneration and concentration, the solution concentration is increased and becomes a regenerated solution 423 and flows back to the liquid storage tank 400, and exchanges heat with the dehumidified solution 413 in the liquid storage tank 400. After heat exchange, the dehumidified solution 413 becomes a regeneration solution 421 and enters the regenerator 100. After heat exchange, the regeneration solution 423 becomes a dehumidification solution 411, and after heat exchange with the heat exchange fluid in the cold end heat exchange component 310, it becomes a low-temperature solution 412 and then enters the dehumidifier 300.

[0058] Air working process: the air to be dehumidified 301 is cooled and dehumidified by the low-temperature solution 412 in the dehumidifier 300, and becomes the dehumidified air 302 with suitable temperature and humidity, and is sent into the indoor environment space; the air 101 for regeneration enters the regenerator 100, and the high-temperature solution 422 discharges heat and moisture to the air 101 for regeneration, and its own concentration increases, and the regenerated air 102 is directly discharged into the atmosphere.

[0059] See also Figure 2 As shown, it is basically the same as the first embodiment, except that, in this embodiment, the solution flow of the regeneration solution 421 entering the hot end heat exchange component 110 is eliminated, and the heat required in the regeneration process of the dehumidification solution is completely provided by the heat generated by the coil component.

[0060] In this embodiment, in the second embodiment of the present application, the working process of the heat exchange fluid is the same as that of the above embodiment, and the working process of the dehumidification solution is as follows:

[0061] The dehumidification solution 411 is driven by the second solution pump 420 from the liquid storage tank 400 to flow into the cold end heat exchange component 310, absorbs cold energy to become the low temperature solution 412, and then enters the dehumidifier 300 to cool and dehumidify the dehumidified air 301, and then becomes the dehumidified solution 413 and flows back to the liquid storage tank 400; the regeneration solution 421 is driven by the first solution pump 410 through the liquid storage tank 400, and is divided into two paths before reaching the coil assembly. One path enters the cooling cavity of the first coil assembly 211 through the first solution inlet 520, and is connected to the first coil assembly 212. 11 for heat exchange, absorbing the waste heat generated by the operation of the first coil assembly 211, and the other way enters the cooling chamber of the second coil assembly 212 through the second solution inlet 521 to absorb the waste heat generated by the second coil assembly 212. The regenerated solution 421 absorbs the heat to become a high-temperature solution 422, and then enters the regenerator 100. The air 101 for regeneration that also enters the regenerator 100 cools down and absorbs moisture in the high-temperature solution 422. The solution concentration of the high-temperature solution 422 is increased, and it becomes a regenerated solution 423 that flows back to the storage tank 400.

[0062] See also Figure 3 As shown, in the third embodiment of the present application, based on the first embodiment, the dehumidification method of the dehumidifier 300 is changed from a packed tower or a spray tower to a first membrane dehumidification assembly 320. The first membrane dehumidification assembly 320 separates the air and the dehumidification solution, performs heat and mass exchange through the membrane, and prevents other gases or liquid solutions from penetrating through the semipermeable membrane, which is conducive to overcoming the droplet carryover problem in the traditional direct contact system.

[0063] The first membrane dehumidification component 320 is mainly composed of parallel plate membranes or hollow fiber membranes, wherein the parallel plate membrane component maintains equal spacing between membranes to form a flow channel, and has a simple structure, small pressure loss, and easy construction; the air to be treated in the hollow fiber membrane component flows outside the tube (shell side) or inside the tube (tube side), and its dehumidification effect is better.

[0064] See also Figure 4 As shown, in the fourth embodiment of the present application, it is basically the same as the third embodiment, except that, in this embodiment, the regenerator 100 is changed from a packed tower or a spray tower to a second membrane dehumidification component 120, and the structure of the second membrane dehumidification component 120 is the same as the first membrane dehumidification component 320, which will not be repeated here.
