Problems solved by technology

Therefore, if the opening value calculated by the PID humidity controller is directly given to the control unit of the high-pressure micro-mist humidifier, when the value of e(t) is large, it is easy to appear step-wise humidification when starting up, and cannot Meet the needs of normal and stable operation of the system

Embodiment Construction

[0039] The technical solutions of the present invention will be further described below in conjunction with the accompanying drawings and specific embodiments.

[0040] A stable humidification control method based on PID control, including a humidification system, the humidification system includes a first PID humidity controller, a second PID humidity controller, a core controller, a high-pressure micro-mist humidifier and a steam humidifier; One PID humidity controller is used to calculate the total amount of humidification opening V1 and the opening Vs of the steam humidifier; the second PID humidity controller is used to calculate the humidification opening component V2 and the opening Vw of the high-pressure micro-mist humidifier;

[0041] Include the following steps:

[0042] Step 101: The core controller judges whether the humidification system is running; if not, the first PID humidity controller calculates Vs=0 and outputs it to the steam humidifier, and the second PI...

Abstract

The invention relates to a method for controlling a humidification process in a humidification system of a combined air conditioner. The purpose is to provide a stable humidification control method based on PID control, including the following steps: the first PID humidity controller and the second PID humidity controller respectively calculate V1 and V2 and judge whether V2 is greater than 14, and then judge whether V2 is greater than 0, whether V1 is greater than V2, calculate VS and VW according to the judgment results and output them to the steam humidifier and high-pressure micro-mist humidifier respectively; when starting up, after calculating V1 and V2, first judge whether V2 is greater than 14, if so, Then by revising the calculation formula of V2, recalculate V2 so that V2 is less than 14, and then judge whether V2 is greater than 0, whether V1 is greater than V2, and calculate VS and VW according to the judgment results and output them to the steam humidifier and high-pressure micro-mist humidifier respectively. device. The invention can effectively avoid the step-over-step humidification phenomenon when starting up, and ensure the efficient and stable humidification process after starting up.

Description

technical field [0001] The invention relates to a method for controlling a humidification process in a humidification system of a combined air conditioner. Background technique [0002] In the prior art, the high-pressure micro-mist humidifier is the core component of the humidification system of the combined air conditioner. The high-pressure micro-mist humidifier is composed of a core controller, a PID humidity controller, a high-pressure pump, a classification valve, a nozzle unit, and a high-pressure pipeline. . The PID controller receives the control voltage signal of the combined air conditioner, adjusts the switch of the grading valve to realize the adjustment of the humidification amount: each nozzle unit (nozzle unit composed of different numbers of nozzles) corresponds to a grading valve, for example, the first-stage grading valve corresponds to the nozzle The nozzle unit with the number of 1, the second-stage grading valve corresponds to the nozzle unit with the ...
