Along with the rapid development of national economy of China, the problem of energy shortage is remarkable, and the problems of more and more severe resource utilization and environmental deterioration cause wide attention of people. Meanwhile, people have more requirements on safety, health, environmental protection and energy conservation for the working environment and the living environment of the people, and the development of the building industry is further promoted.
Under the background, the air conditioning industry also moves towards the goals of green energy conservation, health and comfort, but compared with the air conditioning research and development technology in China, the requirement on energy consumption is generally higher. As is well known, building energy conservation has been recognized as the most promising, most directly effective way of various energy conservation approaches. The energy consumption of the air conditioner accounts for 50% -60% of the energy consumption of the whole building, and the energy conservation of the air conditioning system can directly influence the energy conservation of the building. Along with the accelerated transformation of world energy sources to green, low-carbon and clean, renewable energy sources gradually become the core of global energy transformation. The renewable energy meets the requirements of low carbon and emission reduction, conforms to the transformation direction of the Chinese industrial structure, and can effectively guarantee the energy safety of China. In order to promote green development and realize comprehensive green transformation of economic and social development, the air conditioning system industry should actively respond and be in line with the development trend. At present, the prior air conditioning technology mostly adopts fluorine-chlorine hydrocarbon refrigerants, which causes greenhouse effect and pollutes the environment.
In order to solve the problems, the dehumidification rotary air conditioning system is an air conditioning mode with great development potential and research significance based on the aspects of environmental protection, energy conservation, air quality and the like. The existing dehumidification rotary wheel air conditioner generally comprises a dehumidification rotary wheel, an air cooler, an air heater, an auxiliary electric heater and other main equipment, wherein the dehumidification rotary wheel plays a role in processing latent heat load of air, and the air cooler, the air heater and the auxiliary electric heater play a role in processing sensible heat load of air. However, the regeneration energy consumption of the dehumidification rotary wheel is one of the main energy consumption of the rotary wheel dehumidification air conditioner, the regeneration temperature required by the conventional dehumidification rotary wheel air conditioner system is too high, the regeneration rotary wheel air conditioner system is heated to 80-120 ℃ by adopting an electric heating mode, and a large amount of electric energy is consumed. On the one hand, from the energy cascade utilization andin view of the fact that the electric energy is converted into heat energy, the grade of the energy source is not matched with the grade of the heat consumption, and is unreasonable,

the loss is large and the waste heat recycling is not considered; on the other hand, the dehumidification rotary wheel air conditioning system does not effectively utilize the regenerated air in winter and has low system efficiency.
In summary, the existing desiccant wheel air conditioning system has the following disadvantages: (1) the regeneration energy consumption is large; (2) the heat of adsorption is seriously wasted; (3) the dehumidification rotary air-conditioning system in winter has low efficiency.
