Description

Technical Field

[0001] The present invention belongs to the technical field of air-conditioning and refrigeration equipment, and in particular to an air-conditioning system with carbon dioxide capture and resource utilization functions, which can capture carbon dioxide in the environment and convert it into useful products such as formate. Background Art

[0002] With the rapid development of society and people's pursuit of higher living standards, air conditioning has become a necessity of life.

[0003] Air conditioning systems based on absorption refrigeration use environmentally friendly refrigerants such as water as refrigerants and can be powered by various renewable energy sources, making them an ideal choice for the development of low-carbon air conditioning. Existing absorption refrigeration-based air conditioning systems consist of a generator, absorber, solution pump, condenser, throttle valve, and evaporator. The generator, absorber, and solution pump form the absorbent cycle, while the condenser, throttle valve, and evaporator form the refrigeration cycle. Using the generator and condenser, a heat-driven distillation process separates water from the low-concentration absorbent, resulting in both refrigerant water and a high-concentration absorbent. This process first requires heating the generator to increase the temperature of the circulating absorbent; then, a cooling source must be used to cool the absorbent. This not only wastes energy, but also results in low single-stage refrigeration efficiency due to the negative effects of diffusion.

[0004] Moreover, the existing air-conditioning system itself does not have the ability to capture carbon dioxide, let alone realize carbon dioxide resource utilization. Summary of the Invention

[0080] like Figure 1 As shown, the working principle of the air conditioning system with carbon dioxide capture and resource recovery function of the present invention is as follows:

[0081] In the first comprehensive treatment unit 1, the electrodes in the chambers on both sides are energized, the electrode 105 in the chamber 101 is connected to the positive electrode of the first power supply 61, and the electrode 106 in the chamber 104 is connected to the negative electrode of the first power supply 61. The solution solute from the first liquid storage tank 51 is generally a single or mixed electrolyte absorbent such as LiCl, LiBr and CaCl2, and is introduced into the chamber 103, and the external air containing carbon dioxide is introduced into the chamber 104; under the action of the electric field attraction, the anions in the solution are attracted by the electrode 105 and migrate toward the positive electrode, the anions pass through the anion selective permeable membrane 108, and form an anion-enriched solution in the chamber 102; the cations in the solution are attracted to the vicinity of the electrode 106 through the cation selective permeable membrane, forming an alkaline solution in the chamber 104, and capturing carbon dioxide gas, and then a carbon dioxide electrochemical reaction occurs in the area where the electrode 106 is located to generate anions such as formate ions and carbonate ions. The solution in chamber 103 is diluted and turned into pure water, which is sent to the water storage tank 9 and then sent to the evaporator 11 for use as a refrigerant to achieve the effect of refrigeration and air conditioning; the solution in chamber 102 enters chamber 302 of integrated processing unit three 3, and the solution in chamber 104 enters chamber 304 of integrated processing unit three 3.

[0083] Through the above process, the present invention not only effectively avoids the negative impact of temperature increase and diffusion caused by heating on the refrigeration efficiency of existing air-conditioning systems based on absorption refrigeration, but also can capture carbon dioxide in the environment and convert it into useful products, integrating the air-conditioning process with the carbon dioxide capture and resource utilization process, so that the system has the dual functions of reducing carbon dioxide emissions and directly reducing the total amount of carbon dioxide.
