Embodiment Construction
[0018] Below, the substantive features and advantages of the present invention will be further described in conjunction with examples, but the present invention is not limited to the listed examples.
[0019] see figure 1 As shown, a method for controlling the constant humidity of an air conditioner in an automobile painting workshop comprises the following steps:
[0020] S101: real-time detection of the current ambient moisture content of the external ambient air of the air-conditioning system;
[0021] S102: According to the preset relationship between the current environmental moisture content and the set target environmental moisture content, calculate the water consumption required to make the ambient air in the workshop reach the target environmental moisture content;
[0022] S103: According to the corresponding relationship between the water consumption and the frequency conversion frequency of the frequency conversion humidification motor, calculate the operating fr...

The invention relates to an air conditioner constant humidity control method and system for an automobile coating workshop. The method comprises the steps that current environment moisture content of external environment air of an air conditioning system is detected in real time; according to a preset relation between the current environment moisture content and target environment moisture content, water consumption needed for workshop interior environment air to reach the target environment moisture content is calculated; and according to a corresponding relation between the water consumption and a variable frequency of a variable frequency humidification motor of the air conditioner, a working frequency of the variable frequency humidification motor is calculated, and the variable frequency humidification motor is adjusted according to the work frequency to work to adjust the air conditioner humidity. According to the air conditioner constant humidity control method and system for the automobile coating workshop, intelligent adjustment for the air conditioner humidity is achieved, the problems that in an existing workshop temperature and humidity control, mutual interference between the temperature and the humidity is too much, coupling is too high, and stabilizing time is too long are solved.
Description
technical field [0001] The invention belongs to the technical field of automobile painting, and in particular relates to an air conditioner constant humidity control method and system for automobile painting workshops. Background technique [0002] In automobile spraying, there are high requirements for the temperature and humidity accuracy of the spray booth. If the temperature and humidity control error is too large, it will have a certain impact on the quality of the car body. Therefore, the temperature and humidity control is more important for the entire system. Since the air conditioning system itself has a large hysteresis and the temperature and humidity have a large coupling in the process, the control of temperature and humidity has always been one of the key research contents of the paint shop. [0003] In the existing greenhouse temperature control, the strategy of using PID control for each functional section is adopted. The interference between each functional ...
