First Order Inertia Lag PID Independent Control Method for Cold Water Valve of Clean Air Conditioner
The first order inertial control deviation item of the cold water valve causes the poor control effect of headroom temperature regulation and humidity.Therefore,a first-order inertia lag PID independ-ent control method for chilled water valve of clean air conditioner is proposed.In this method,the first or-der inertia lag model of the environment and the cold water valve is established considering the basic infor-mation of the indoor environment;the fresh air volume of indoor clean air conditioning temperature and hu-midity is calculated as the constraint of independent control of temperature and humidity of the cooling wa-ter valve of clean air conditioning;the adaptive immune genetic algorithm is used to optimize the parame-ters of PID controller,based on which the independent control of the temperature and humidity of the cool-ing water valve of the clean air-conditioning is realized.The experimental results show that the method is effective and energy-saving.
