Problems solved by technology

[0003] At present, there are two ways to adjust the air conditioning system: one is manual adjustment, the adjustment is not timely, the humidity fluctuates too much, the accuracy is low, it does not meet the requirements, and the energy consumption is relatively large
The other is automatic adjustment, the control given value of this adjustment method is fixed, the response period is long, and the energy consumption is relatively large

Embodiment 1

[0060] In a textile workshop, if the humidity control interval (S1-S2) is set to 55%-65%, then the control given value Sp is 60% when the system is just started. The sampling interval N is set to 5 minutes, the proportional coefficient x is set to -0.1, y is set to -0.08, and z is set to 0.1.

[0061] Sample value one:

[0062] The air temperature in the workshop is 29°C, the humidity is: 56%, and the enthalpy value Hi1=65.4

[0063] The air temperature outside the workshop is 25°C, the humidity is: 47%, and the enthalpy value Ho1=48.8

[0064] The air temperature in the air mixing chamber is: 28°C, the humidity is: 53%, and the enthalpy value Hm1=60.4

[0065] Sample value two:

[0066] The air temperature in the workshop is 28.6°C, the humidity is: 57%, and the enthalpy value Hi2=64.75

[0067] The air temperature outside the workshop is 26°C, the humidity is: 49%, and the enthalpy value Ho2=52.5

[0068] The air temperature in the mixing chamber is: 28°C, the humidity ...

Abstract

The invention relates to a method for controlling interval humidity by adjusting set values intelligently. The method comprises the following steps of: acquiring a preset value of a humidity control interval (S1 and S2); setting a controlled set value Sp to be (S1+S2) / 2; acquiring a preset value of interval time N of sampling, and starting to time for N minutes; acquiring temperature and humidity signals outside a workshop and in the workshop and an air mixing chamber for three times, and calculating and storing an enthalpy value; calculating a variation ratio; calculating an intermediate variable S; comparing the intermediate variable S with a set interval to generate a new set value; and recording sampling values of the recent two times and acquiring data again. Compared with the prior art, the method has the advantages of high efficiency, energy conservation, reduction of energy waste, high control accuracy, reduction of fluctuation of temperature and humidity, contribution to improving the quality of products, quick response speed, capability of regulating the set values quickly during the change of environment conditions to realize quick response, and reduction of labor cost due to automatic control.

Description

technical field [0001] The invention relates to a temperature and humidity control method, in particular to an interval humidity control method for intelligently adjusting a given value. Background technique [0002] The workshops of textile factories and cigarette factories have relatively high humidity requirements, and the humidity is required to be maintained within a certain range. The adjustment of the humidity in the workshop is realized through the air conditioning system. This air-conditioning system is composed of an air-conditioning room, a fan, a water pump, a spray room, an adjustable window and an air duct. [0003] At present, there are two ways to adjust the air conditioning system: one is manual adjustment, the adjustment is not timely, the humidity fluctuates too much, the accuracy is low, it does not meet the requirements, and the energy consumption is relatively large. The other is automatic adjustment. The control given value of this adjustment method ...
