Numerical Simulation and Research about Fixed - point Cooling Control of Air Conditioning

This paper designs an indoor air conditioning simulation control system, according to GB50019-2015 industrial building heating and ventilation and air conditioning design specifications, "air conditioning variable air volume terminal device" standard. Through the use of CFD designs software OpenFOAM, the closed indoor air conditioning system is simulated. The system simulates the wind speed of the designated site in the room. Combining the results of numerical simulation with CFD control theory and PID control algorithm, it is proved that the air conditioning fixed-point refrigeration system can achieve good control effect. This paper realizes the fixed-point wind speed control of air conditioning indoor personnel, which is not available in modern air conditioning. The simulation model and control strategy can be widely used in intelligent air conditioning design, which can promote the construction of intelligent city.
