Description
Technical Field
[0001] The present invention relates to the technical field of carbon capture, and in particular to an air conditioning system coupled with carbon dioxide capture. Background Art
[0002] Direct air capture (DAC) technology is a new type of carbon capture technology that has emerged in recent years. Its advantage is that it can capture and process CO2 emitted by small fossil fuel combustion devices and mobile emission sources such as vehicles, and can be arranged close to CO2 utilization or storage sites to avoid transportation needs, or arranged in the same area with stationary source CCS (Carbon Capture and Storage, CCS) systems to share existing transportation facilities to reduce costs. Due to its significant negative carbon potential, it is usually classified as negative emission technology or carbon removal technology. Compared with other technologies that mainly target fixed emission sources, the location of direct air capture devices has greater flexibility and almost no theoretical upper limit on 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 and application of this type of technology.
[0003] The DAC system is generally composed of an air suction device, a CO2 adsorption device, a desorption device and other auxiliary devices. The air suction device mostly enriches the air through negative pressure equipment such as compressors, and the CO2 adsorption / desorption device captures CO2 in the air through solid adsorption materials or liquid absorption materials. After the absorption / adsorption is saturated, the material is regenerated through desorption methods such as temperature and pressure changes to obtain 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. Among them, the combination of direct air carbon capture module and air conditioning system is a new direction to achieve leapfrog development of DAC. The DAC and air conditioning coupling system can reduce the suction device of traditional DAC and realize the integration of temperature regulation and carbon removal, purifying indoor air while completing CO2 effective capture. However, the existing system generally has problems such as limited adsorption capacity of air carbon capture module, high energy consumption of CO2 desorption, inconvenient module disassembly and replacement, complex process and low degree of digitization.

[0027] Compared with the prior art, the present invention has the following advantages:
[0028] 1. The above-mentioned air-conditioning system coupled with carbon dioxide capture firstly sets a carbon capture module in the air-conditioning body, so that air can pass through the carbon capture module and then reach the air outlet of the air-conditioning after entering from the air inlet of the air-conditioning, so that the carbon capture module can effectively adsorb carbon dioxide in the air, and a carbon desorption module is also set up at the same time, and the carbon dioxide on the carbon capture module is sucked by a negative pressure pump, and the carbon dioxide on the carbon capture module is blown off by a purge pump. When the carbon dioxide on the carbon capture module is less enriched, only the negative pressure pump can be used to suck the carbon dioxide on the carbon capture module and store it in a gas storage tank. When the carbon dioxide on the carbon capture module is more enriched, the negative pressure pump and the purge pump are turned on at the same time for blowing and absorption, and the gas in the gas storage tank can be used for blowing, which is beneficial to desorbing the carbon dioxide enriched on the carbon capture module, releasing the carbon dioxide capacity of the carbon capture module, and ensuring the purification effect of the carbon capture module.

[0029] 2.

[0030] 3. The air-conditioning system is also provided with a controller, which can control the switches of the negative pressure pump and the purge pump 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 means that the carbon capture module has a good treatment effect and a large adsorption capacity, and the carbon capture module desorption treatment may not be performed. 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 means that the treatment effect of the carbon capture module decreases and the adsorption capacity decreases, and the carbon capture module can be subjected to adsorption and desorption treatment. When the carbon dioxide concentration detected by the carbon dioxide sensor is greater than the carbon dioxide concentration B, the carbon capture module has basically no treatment effect and the adsorption capacity is basically 0. The carbon capture module needs to be desorbed as a whole to release the adsorption capacity of the carbon capture module. Therefore, the controller and the carbon dioxide sensor realize automatic control of the desorption of the carbon capture module, ensure the effect of removing carbon dioxide by the air-conditioning system, and improve the degree of digital control.

The air-conditioning system can also be provided with an air-conditioning return air vent, so that the air-conditioning outlet is connected to the air-conditioning return air vent and the external environment through a three-way valve.

This embodiment is implemented based on the technical solution of the present invention, and provides a detailed implementation method and specific operation process, but the protection scope of the present invention is not limited to the following embodiments.
[0037] An air conditioning system 100 coupled with carbon dioxide capture in some embodiments is described in detail below with reference to the accompanying drawings.
[0038] like Figures 1 to 3 As shown, in one embodiment, an air conditioning system 100 coupled with carbon dioxide capture is provided, comprising an air conditioning body 10, a carbon capture module 20 and a carbon desorption module 30;
[0039] Among them, the air-conditioning body 10 is provided with an air-conditioning air inlet 11 and an air-conditioning air outlet 12; the carbon capture module 20 is arranged in the air-conditioning body 10, and is respectively connected with the air-conditioning air inlet 11 and the air-conditioning air outlet 12; the carbon desorption module 30 includes a negative pressure pump 31, a gas storage tank 32 and a purge pump 33 which are connected in sequence, the inlet of the negative pressure pump 31 is connected with the outlet of the carbon capture module 20, and the outlet of the purge pump 33 is connected with the inlet of the carbon capture module 20.
[0040] The above-mentioned air conditioning system 100 coupled with carbon dioxide capture first sets a carbon capture module 20 in the air conditioning body 10, so that air can pass through the carbon capture module 20 and then reach the air conditioning outlet 12 after entering from the air conditioning inlet 11, so that the carbon capture module 20 can effectively adsorb carbon dioxide in the air. At the same time, a carbon desorption module 30 is also set, and the carbon dioxide on the carbon capture module 20 is sucked by a negative pressure pump 31, and the carbon dioxide on the carbon capture module 20 is blown off by a purge pump 33. When the carbon dioxide on the carbon capture module 20 is less enriched, it can only A negative pressure pump 31 is used to absorb the carbon dioxide on the carbon capture module 20 and store it in a gas storage tank 32. When the carbon dioxide on the carbon capture module 20 is highly enriched, the negative pressure pump 31 and the purge pump 33 are turned on at the same time for blowing and absorption. The gas in the gas storage tank 32 can be used for blowing, which is beneficial to desorbing the carbon dioxide enriched on the carbon capture module 20, releasing the carbon dioxide capacity of the carbon capture module 20, and ensuring the purification effect of the carbon capture module 20. At the same time, recycling the gas in the gas storage tank 32 for blowing is beneficial to saving desorption costs.
[0041] Specifically, in one embodiment, the air conditioning system 100 includes a controller, which is electrically connected to the negative pressure pump 31 and the purge pump 33 .
[0042] In one embodiment, a carbon dioxide sensor is provided in the air-conditioning outlet 12 for detecting the carbon dioxide concentration in the air-conditioning outlet 12, and a controller is electrically connected to the carbon dioxide sensor for controlling the negative pressure pump 31 and the purge pump 33 according to the carbon dioxide concentration.
[0043] The above-mentioned air conditioning system 100 coupled with carbon dioxide capture is provided with a carbon dioxide sensor at the air conditioning outlet 12, so that the quality of air 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, so as to timely discover the treatment effect of the carbon capture module 20 and further replace the carbon capture module 20 or desorb the enriched carbon dioxide of the carbon capture module 20.
[0044] Furthermore, in one embodiment, the control method of the controller includes the following specific steps:
[0045] A carbon dioxide concentration A and a carbon dioxide concentration B are preset, and the carbon dioxide concentration B is greater than the carbon dioxide concentration A;
[0046] 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 purge pump 33 to be turned off;
[0047] 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 to turn on;

[0049] The air-conditioning system 100 is also provided with a controller, and the controller can control the switches 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 means that the treatment effect of the carbon capture module 20 is better and the adsorption capacity is larger, and the carbon capture module 20 desorption treatment 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 means that the treatment effect of the carbon capture module 20 is reduced and the adsorption capacity is reduced, and the carbon capture module 20 can be subjected to adsorption and desorption treatment. When the carbon dioxide concentration detected by the carbon dioxide sensor is greater than the carbon dioxide concentration B, the carbon capture module 20 has basically no treatment effect and the adsorption capacity is basically 0. 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 automatic control of the desorption of the carbon capture module 20 to ensure the effect of removing carbon dioxide by the air-conditioning system 100.

[0051] Furthermore, in one embodiment, the control method of the controller includes the following specific steps:
[0052] Preset carbon dioxide concentration C;
[0053] 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 outlet 12 of the air conditioner with the external environment;
[0054] 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 outlet 12 of the air conditioner and the air return outlet 13 of the air conditioner.
[0055] The air conditioning system 100 can also be provided with an air conditioning return air vent 13, so that the air conditioning outlet 12 is connected to the air conditioning return air vent 13 and the external environment through a three-way valve. By cooperating with the controller, when the treatment effect of the carbon capture module 20 is not ideal, the air treated by the carbon capture module 20 can be passed through the air conditioning return air vent 13 for secondary treatment, thereby improving the carbon dioxide treatment effect of the air conditioning system 100.

The controller is electrically connected to the first air vent valve 34 and the second air vent valve 35, respectively, and is used to control the first air vent valve 34 and the second air vent valve 35 according to the carbon dioxide concentration.
[0057] In this specific embodiment, the control method includes the following specific steps:
[0058] A carbon dioxide concentration A and a carbon dioxide concentration B are preset, and the carbon dioxide concentration B is greater than the carbon dioxide concentration A;
[0059] 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 vent valve 34 and the second air vent valve 35 to close;
[0060] 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 and the first air vent valve 34 to open;
