[0002] The traditional air conditioning unit control method is to detect the temperature and humidity of the controlled environment, and then compare the temperature and humidity of the controlled environment with the temperature and humidity of the controlled environment, control the opening or opening of the proportional integral valve, control the frequency conversion The output frequency of the controller, the control host unit is turned on or off. This control method cannot combine the temperature and humidity of the controlled environment for calculation, that is, it cannot perform specific enthalpy calculations through temperature and humidity, and output the control value to the air conditioning unit. Therefore The opening or opening of the proportional-integral valve of the air-conditioning unit, the output frequency of the inverter, and the opening or closing of the main unit of the air-conditioning unit cannot be precisely controlled, which cannot effectively improve energy utilization efficiency, save energy, and cause energy waste

The invention discloses a controlling method for the Hpid precise air condition. It selects a controller which can be the PLC programmable logic controller, the DDC directly digital controller or the singlechip controlling system, which are all set with the Ai simulated input, the Ao simulated output, the Di digital input and Do digital output interface. When the controller is input the Hpid operation formula and the controlling program, it compounds the temperature and the humidity of the environment to do the enthalpy of the Hpid formula, then it outputs the controlling value to the proportion integral valve, the converter and the air condition machine group. So it can control the start or opening of the proportion integral valve, the output frequency of the converter, the start or close of the main machine group precisely to improve the energy using efficiency and save the energy.
