Software design of CO2 variable frequency air conditioning system
CO2 variable frequency air conditioning combines the advantages of CO2 en-vironmental protection concept and energy saving practicability of variable frequency air conditioning,explores the control method of CO2 variable frequency air conditioning thr-ough the method of combining theory with practice,summarizes the compressor speed control logic and electronic expansion valve control logic of CO2 variable frequency air con-ditioning,and at the same time makes three necessary protections for the system.Finally,the function of CO2 variable frequency air conditioner is verified through software design.The system finally enters a stable state under a certain ambient temperature,and the system can meet the temperature control requirements under different ambient tem-peratures.
