Embodiment 1

[0027] A decoupling automatic adjustment method for HVAC laboratory working conditions, such as figure 1 As shown, it specifically includes the following steps:

[0028] (1) Input the set temperature and humidity in the predictive algorithm controller;

[0029] (2) Predictive algorithm The controller calculates the amount of cold heat and steam that needs to be put into the room according to the actual temperature and humidity and the preset temperature and humidity; and calculates it by combining the heat load of the equipment, the parameters of the cold heat of the measured sample and the heat leakage of the room The actual required cooling machine input;

[0030] (3) Automatically control the start-up and input of the cold machine according to the actual required input of the cold machine;

[0031] (4) Detect the parameters of the evaporator after putting in the cooling capacity (including the temperature and humidity of the air entering and leaving the evaporator, the te...

Abstract

The invention discloses a heating and ventilation laboratory working condition decoupling automatic adjusting method. The heating and ventilation laboratory working condition decoupling automatic adjusting method adopts two process automatic control PID to respectively control electric heating heat and steam quantity in a room, adopts an automatic grading algorithm to control the input of refrigerating capacity, and adopts the algorithm to calculate the quantity of steam condensation generated by an evaporator in the room when the evaporator encounters heat. According to the expected dry and wet bulb temperature and the actual dry and wet bulb temperature, the input heat quantity, cold quantity and steam quantity are calculated, decoupling control over temperature and humidity can be achieved for PID process control over dry bulb PID and humidity PID process control, and automatic working condition adjustment is achieved.
