Description
TECHNICAL FIELD
[0001] The utility model relates to carbon capture technology field especially is coupled carbon dioxide capture's air conditioning system. BACKGROUND
[0002] Direct air capture (DAC) technology is a new carbon capture technology category in recent years, which has the advantages of capturing and processing CO2 emitted by small fossil fuel combustion devices and mobile emission sources such as vehicles, and can be arranged near CO2 utilization or storage sites to avoid transportation needs, or arranged in the same area as the fixed source CCS (Carbon Capture and Storage, CCS) system to reduce costs by sharing existing transportation facilities. Because of its significant negative carbon potential, it is usually classified as a negative emission technology or carbon removal technology. Compared with other technologies that mainly capture fixed emission sources, the arrangement of direct air capture devices has greater flexibility and almost no theoretical upper limit of emission reduction. At the same time, the high energy consumption and high cost caused by the low CO2 partial pressure in the air are the main bottlenecks limiting the large-scale demonstration application of this technology.
[0003] The DAC system generally consists of an air suction device and a CO2 adsorption device, a desorption device, and other auxiliary devices. The air suction device is mostly enriched by a compressor or other negative pressure equipment. The CO2 adsorption / desorption device captures CO2 in the air by solid adsorption material or liquid absorption material, and then regenerates the material by changing the temperature and pressure after absorption / adsorption saturation, thereby obtaining high-concentration CO2.
[0004] The integration of DAC system with existing equipment is an effective means to reduce the overall energy consumption and cost of DAC. The combination of direct air carbon capture module and air conditioning system is a new direction for the leap-forward development of DAC. The DAC and air conditioning coupled system can reduce the air suction device of traditional DAC and realize temperature regulation and carbon removal integration, purify indoor air while effectively capturing CO2. However, the existing system generally has limited adsorption capacity of the air carbon capture module, high CO2 desorption energy consumption, inconvenient module disassembly and replacement, complex process, and low digitalization degree.

DETAILED DESCRIPTION
[0029] The utility model will be described in detail below in combination with the drawings and specific embodiments. The embodiment is implemented on the premise of the technical scheme of the utility model, and detailed implementation mode and specific operation process are given, but the protection scope of the utility model is not limited to the following examples.
[0030] The air conditioning system 100 coupled with carbon dioxide capture in some embodiments will be described in detail below in combination with the drawings.
[0031] As shown in the drawings, Figures 1 to 3 In an embodiment, an air conditioning system 100 coupled with carbon dioxide capture is provided, comprising an air conditioner body 10, a carbon capture module 20 and a carbon desorption module 30.
[0032] The air conditioner body 10 is provided with an air conditioner air inlet 11 and an air conditioner air outlet 12; the carbon capture module 20 is arranged in the air conditioner body 10 and communicates with the air conditioner air inlet 11 and the air conditioner air outlet 12 respectively; the carbon desorption module 30 comprises a negative pressure pump 31, a gas storage tank 32 and a purge pump 33 which are communicated in sequence, the inlet of the negative pressure pump 31 communicates with the outlet of the carbon capture module 20, and the outlet of the purge pump 33 communicates with the inlet of the carbon capture module 20.
[0033] The air conditioner system 100 coupled with carbon dioxide capture is provided with the carbon capture module 20 in the air conditioner body 10, so that the air entering from the air conditioner air inlet 11 can pass through the carbon capture module 20 and then reach the air conditioner air outlet 12, so that the carbon capture module 20 can effectively adsorb carbon dioxide in the air. Meanwhile, the carbon desorption module 30 is also provided, the carbon dioxide on the carbon capture module 20 is sucked by the negative pressure pump 31, and the carbon dioxide on the carbon capture module 20 is blown off by the blowing pump 33. When the carbon dioxide on the carbon capture module 20 is less enriched, only the negative pressure pump 31 can be used to suck the carbon dioxide on the carbon capture module 20 and store it in the gas storage tank 32. When the carbon dioxide on the carbon capture module 20 is more enriched, the negative pressure pump 31 and the blowing pump 33 are opened at the same time for blowing and sucking, and the gas in the gas storage tank 32 can be used for blowing, which is beneficial to desorb the enriched carbon dioxide on the carbon capture module 20, release the carbon dioxide capacity of the carbon capture module 20, ensure the purification effect of the carbon capture module 20, and recycle the gas in the gas storage tank 32 for blowing, which is beneficial to save the desorption cost.
[0034] Specifically, in an embodiment, the air conditioner system 100 comprises a controller, and the controller is electrically connected with the negative pressure pump 31 and the blowing pump 33.
[0035] In one embodiment, a carbon dioxide sensor is arranged in the air conditioner air outlet 12, which is used to detect the carbon dioxide concentration in the air conditioner air outlet 12, and the controller is electrically connected with the carbon dioxide sensor, which is used to control the negative pressure pump 31 and the blowing pump 33 according to the carbon dioxide concentration.
[0036] The air conditioner system 100 coupled with carbon dioxide capture is provided with the carbon dioxide sensor in the air conditioner air outlet 12, so that the air quality after being treated by the carbon capture module 20 can be monitored in real time, that is, the treatment effect of the carbon capture module 20 can be monitored in real time, which is beneficial to find the treatment effect of the carbon capture module 20 in time, and further replace the carbon capture module 20 or desorb the enriched carbon dioxide on the carbon capture module 20.
[0037] Further, in an embodiment, the control method of the controller comprises the following specific steps:
[0038] The carbon dioxide concentration A and the carbon dioxide concentration B are preset, and the carbon dioxide concentration B is greater than the carbon dioxide concentration A;
[0039] When the carbon dioxide concentration detected by the carbon dioxide sensor is less than the carbon dioxide concentration A, the controller controls the negative pressure pump 31 and the blowing pump 33 to be closed;
[0040] When the carbon dioxide concentration detected by the carbon dioxide sensor is greater than the carbon dioxide concentration A and less than the carbon dioxide concentration B, the controller controls the negative pressure pump 31 to be opened;
[0041] When the carbon dioxide concentration detected by the carbon dioxide sensor is greater than the carbon dioxide concentration B, the controller controls the negative pressure pump 31 and the purge pump 33 to open.
[0042] The air conditioning system 100 is further provided with a controller, which can control the opening and closing of the negative pressure pump 31 and the purge pump 33 according to the detection result of the carbon dioxide sensor. Therefore, when the carbon dioxide concentration detected by the carbon dioxide sensor is lower than the carbon dioxide concentration A, it indicates that the carbon capture module 20 has a good processing effect and a large adsorption capacity, and the desorption treatment of the carbon capture module 20 can be omitted. When the carbon dioxide concentration detected by the carbon dioxide sensor is greater than the carbon dioxide concentration A and less than the carbon dioxide concentration B, it indicates that the processing effect of the carbon capture module 20 is decreased and the adsorption capacity is decreased, and the carbon capture module 20 needs to be treated. When the carbon dioxide concentration detected by the carbon dioxide sensor is greater than the carbon dioxide concentration B, the carbon capture module 20 basically has no processing effect and the adsorption capacity is basically 0, and the carbon capture module 20 needs to be desorbed as a whole to release the adsorption capacity of the carbon capture module 20. Therefore, the controller and the carbon dioxide sensor realize the automatic control of the desorption of the carbon capture module 20, and ensure the carbon dioxide removal effect of the air conditioning system 100.
[0043] Further, as shown in Figure 1 In an embodiment, the air conditioning body 10 is further provided with an air conditioning return air inlet 13, which is arranged between the air conditioning air inlet 11 and the carbon capture module 20. The air conditioning air outlet 12 is connected to the air conditioning return air inlet 13 and the external environment through a three-way valve. The three-way valve is electrically connected to the controller, and the controller controls the three-way valve according to the carbon dioxide concentration.
[0044] Further, in an embodiment, the control method of the controller includes the following specific steps:
[0045] presetting a carbon dioxide concentration C;
[0046] When the carbon dioxide concentration detected by the carbon dioxide sensor is less than the carbon dioxide concentration C, the controller controls the three-way valve to connect the air conditioning air outlet 12 and the external environment;
[0047] When the carbon dioxide concentration detected by the carbon dioxide sensor is greater than the carbon dioxide concentration C, the controller controls the three-way valve to connect the air conditioning air outlet 12 and the air conditioning return air inlet 13.
[0048] The air conditioning system 100 can be further provided with the air conditioning return air inlet 13, so that the air conditioning air outlet 12 is connected to the air conditioning return air inlet 13 and the external environment through the three-way valve. By cooperating with the controller, when the processing effect of the carbon capture module 20 is not ideal, the air treated by the carbon capture module 20 can be subjected to secondary treatment through the air conditioning return air inlet 13, thereby improving the carbon dioxide treatment effect of the air conditioning system 100.

The controller is electrically connected to the first air valve 34 and the second air valve 35 respectively, and is used to control the first air valve 34 and the second air valve 35 according to the carbon dioxide concentration.
[0050] In this specific embodiment, the control method includes the following specific steps:
[0051] Preset carbon dioxide concentrations A and B, where carbon dioxide concentration B is greater than carbon dioxide concentration A;
[0052] When the carbon dioxide concentration detected by the carbon dioxide sensor is less than the carbon dioxide concentration A, the controller controls the negative pressure pump 31, the purge pump 33, the first air valve 34 and the second air valve 35 to close.
[0053] When the carbon dioxide concentration detected by the carbon dioxide sensor is greater than carbon dioxide concentration A and less than carbon dioxide concentration B, the controller controls the negative pressure pump 31 and the first air valve 34 to open.
[0054] When the carbon dioxide concentration detected by the carbon dioxide sensor is greater than the carbon dioxide concentration B, the controller controls the negative pressure pump 31, the purge pump 33, the first air valve 34 and the second air valve 35 to open.

[0057] In this specific embodiment, the fixed bracket 22 is a metal square fixed frame, and the four sides of the frame are respectively connected to the four inner walls of the air conditioner body 10.
[0058] Specifically, in one embodiment, the carbon capture module 20 has a complete housing with a sealable air inlet and outlet. When the carbon capture module 20 enters the adsorption state, the air inlet and outlet are open to allow air to flow in and out. When the carbon capture module 20 enters the desorption state, the air inlet and outlet are closed and connected to the negative pressure pump 31 and the purge pump 33. Air cannot flow in or out of the carbon capture module 20, but purge gas can enter the carbon capture module 20.
[0059] Specifically, as shown in Figure 3 The air conditioning system 100 further comprises a main power supply and a renewable power supply 40 in an embodiment, the main power supply is electrically connected with the air conditioning body 10, and the renewable power supply 40 is electrically connected with the negative pressure pump 31 and the purge pump 33.
