[Abstract]:In recent years, with the importance of energy conservation and emission reduction and environmental protection in China, people have deepened their understanding of the energy crisis. Low carbon has gradually become the key word of national production and people's daily life. The main requirement for building energy efficiency is to allow central air conditioners to reduce consumption, mainly because of the worldwide shortage of energy and the increasing use of air conditioners. Therefore, in the process of low-carbonization, the consumption reduction of central air-conditioning has become a key issue. Firstly, through reading a lot of references at home and abroad, this paper summarizes the development and research status of central air conditioning. Secondly, this paper introduces the structure and process principle of HVAC system, especially air treatment system. The central air conditioning system first produces the cold (heat) source through the refrigeration unit, then sends the cold (heat) source through the pipeline to each air conditioning end to achieve the purpose of refrigeration (heat). Based on the law of conservation of energy and heat conduction, the mathematical model of air treatment unit is established according to the main process flow of energy consumption characteristics of each working link of central air conditioning system. At the same time, the temperature, humidity, air supply volume and electrical signal of the valve opening of the air supply valve are collected by the industrial control computer, which is the simulation experiment platform of the existing Yanhua control system. The static model of energy consumption equipment (air fan, chilled water pump) in the air treatment system is established by using the least square method. Then, according to the operation characteristics of the air treatment system of central air conditioning system, the optimization goal and constraint conditions of the air processing system are put forward in this paper. An improved ant colony algorithm (ACA) is proposed to optimize the central air-conditioning air processing unit for its nonlinear, large delay and multi-disturbance characteristics. The improved ant colony algorithm is used to solve the minimum power of central air conditioning system. By changing the formula of probability selection and the expression of pheromone volatilization factor in the algorithm, this paper overcomes the phenomenon that the basic ant colony algorithm is prone to stagnation, appears local optimum, and has too many iterations. The search speed and precision of the optimization algorithm are improved, which provides a new and effective method for energy saving optimization of central air conditioning system. Finally, the effectiveness of the improved ant colony algorithm is verified by the small central air conditioning system in the laboratory, and the validity of the improved ant colony algorithm is verified by the different working conditions of the air treatment unit, and the feasibility of the algorithm is fully verified.
