Description
Technical Field
The invention relates to a dehumidification air-conditioning system based on electroosmosis regeneration of a resin drying agent, and belongs to the field of heating ventilation air-conditioning.
Background
Along with the improvement of the living standard of people, higher requirements are put forward on the thermal comfort of the indoor environment of the building, and the total energy consumption of the building is more and more large in our country. The compression type refrigeration air-conditioning system widely used at present has strong cooling capacity and is not limited by environmental conditions, but the compression refrigeration equipment has high investment and operating cost and also has the problem of easy frosting in winter.
Evaporative cooling utilizes the characteristic that water evaporation requires latent heat absorption, and the latent heat of evaporation is absorbed from the air by the evaporation of water in the air, thereby lowering the air temperature. The equipment investment and operating cost of the evaporative cooling system are far lower than those of a compressor air conditioning system. From the perspective of comprehensive utilization of energy and environmental protection, evaporative cooling is a very potential air-conditioning cooling mode. However, the evaporative cooling effect is limited by the climate conditions, and a good cooling effect cannot be obtained in the weather with a high relative humidity. In addition, the air temperature is reduced by adopting direct evaporative cooling, and meanwhile, the humidity of the air is increased, so that the problem of high humidity of the environment is brought.
In high humidity areas and high humidity air after direct evaporative cooling, dehumidification is required. At present, the solid dehumidifying desiccant is generally adopted to absorb moisture and recover the moisture absorption capacity of the solid dehumidifying desiccant in a heating mode. However, in order to carry away the moisture in the desiccant, a large amount of latent heat of vaporization needs to be provided to evaporate the moisture, and the required regeneration equipment at least comprises a heating device, a fan for air for regeneration, an air duct and the like, so that the system is complex and difficult to miniaturize. And after the solid dehumidifying agent is heated and regenerated, the waste heat of the solid dehumidifying agent can be dissipated only after a period of cooling, so that the adsorption efficiency is influenced. Thermal regeneration using solar energy also faces the problem of unstable and discontinuous radiant energy.
Disclosure of Invention
In order to solve the technical defects, the technical scheme adopted by the invention is as follows: based on the electroosmosis regeneration principle, radiation refrigeration, direct evaporative cooling and a desiccant dehumidification regeneration system are coupled, and a dehumidification air-conditioning system based on electroosmosis regeneration of a resin desiccant is provided. The air conditioning system can realize independent temperature and humidity control, meet the requirement of large indoor heat-humidity ratio change and process fresh air more efficiently. Through temperature and humidity feedback, the air inlet position is automatically regulated and controlled, so that different refrigeration modes are generated, the air conditioner is suitable for different climatic conditions (high temperature and high humidity, high temperature and low humidity), the energy waste caused by temperature and humidity combined control in the traditional compression air conditioning system is avoided, and the thermal comfort is obviously improved.
The air conditioning system adopts the resin drying agent with high water absorbability as a dehumidifying material, can absorb water which is hundreds of times or even thousands of times higher than the self weight, adopts an electroosmosis regeneration method for regeneration, only needs a stabilized voltage power supply and electrodes for providing an electric field, has no moving parts, is simple and miniaturized in equipment and has high operation reliability. The liquid water is directly separated from the desiccant by electric field force, and the regeneration at normal temperature can be realized, so that a large amount of energy required for heating the regenerated air is saved, and the increase of cold load caused by the temperature rise of the treated air can be avoided. The regeneration process of the dehumidifying drying agent does not need to provide regeneration air, so that the treated air is prevented from contacting with the regeneration air, the cleanness of the treated air is effectively ensured, and the air quality of the treated air is improved. The electric energy required by the electroosmosis effect can adopt low-voltage direct current generated by renewable energy sources such as wind energy, solar energy and the like, and a storage battery can be adopted for supplying power in cloudy days or at night, so that continuous operation is realized.
The air conditioning system utilizes a radiation refrigeration technology to radiate the heat inside the air conditioning system and reflect the radiation energy emitted by other objects at the same time. In the evaporative cooling process, cooling of the feed water is achieved. In the dehumidification and regeneration process of the drying agent, the heat of adsorption released when the drying agent absorbs moisture is reduced. Therefore, the low-grade heat energy is used as the driving energy of the air conditioning system, and the whole air conditioning system has obvious energy-saving potential.
The technical scheme of the invention is realized by the following measures.
When the ambient air monitored by the temperature and humidity sensor 4 (6-2) positioned at the air inlet 4 (6) is in a low-temperature high-humidity state, the system firstly dehumidifies and then directly evaporates and cools the fresh air. The air valve 3 (16-1), the air valve 4 (6-1) and the air valve 1 (15-1) are opened, the air valve 2 (1) and the direct current fan (12) are started, and high-humidity air is sucked into the electric infiltration pipe. Moisture in the air is removed by the self-adsorption characteristic of the resin drying agent (8-13), so that isothermal dehumidification of high-humidity gas is realized. The air dissipates the sensible heat through the radiation refrigeration coating 2 (8-17), and weakens the adsorption heat of the resin drying agent (8-13), thereby achieving the purposes of temperature reduction and dehumidification. Meanwhile, the photovoltaic stabilized voltage power supply is switched on to carry out the regeneration process of the resin drying agent (8-13). The self-cooling of the water in the radiation refrigeration water tank (3-7) is realized through the radiation refrigeration coating 1 (3-8), and the cooling water is atomized through the ultrasonic atomizer (3-4). The dehumidified air is further introduced into an air duct 1 (2) by a direct current fan (12) to be directly contacted with liquid drops for evaporation heat exchange, and after the temperature is further reduced after isenthalpic humidification, the air is introduced into a room from an air inlet 1 (15).
When the ambient air monitored by the temperature and humidity sensors 2 (14-2) positioned at the air inlets 2 (14) is in a high-temperature low-humidity state, the system is directly subjected to evaporative cooling firstly, and then is subjected to dehumidification through the resin drying agents (8-13). The air valve 1 (15-1), the air valve 2 (14-1) and the air valve 3 (16-1) are opened, and the air valve 4 (6-1) is closed. And the direct current fan (12) is started reversely to introduce external high-temperature low-humidity air and indoor air from the air inlet 1 and the air inlet 2. And simultaneously starting the ultrasonic atomizer (3-4), wherein ambient air enters from the ambient air inlet (3-1) and is mixed with atomized liquid drops to form humid air, and the humid air is sucked into the air channel 1 (2) through the humid air inlet (13). The high-temperature low-humidity air is directly contacted with the humid air in the air duct 1 (2), the temperature of the liquid drops rises after the liquid drops absorb sensible heat of the air, the liquid drops return to the air in a gaseous state after evaporation heat exchange, and therefore the humidity of the air in the air duct 1 (2) is increased, and the air is pumped into the electroosmosis tubes (8-9) through the direct current fan (12). Moisture in the air is removed by means of self-adsorption characteristics, isothermal dehumidification of high-humidity gas is achieved, meanwhile, sensible heat of the air is dissipated out through the radiation refrigeration coating 2 (8-17), adsorption heat of the drying agent is weakened, the purposes of cooling and dehumidification are achieved, and finally the air is introduced into a room from the air inlet 4 (6).
