Embodiment
Further to illustrate the present invention to reach technical approach and effect that predetermined goal of the invention is taken, below in conjunction with
Drawings and Examples, to embodiment, structure, feature and its effect of the present invention, describe in detail as after.
The indoor environmental condition control system of the present invention includes exhaust system, supply air system, temperature control system, TEMP
Device, humidity sensor, VOC sensors, air volumematching unit and controller.In the present embodiment, the indoor environmental condition control system
Unite for the environment (including temperature, humidity and VOC content in spray painting room) for controlling tower drum of wind tower spray painting room.
Exhaust system reduces the VOC content in indoor environment by discharging the VOC of interior, supply air system pass through to
Interior introducing dry air reduces the humidity of indoor environment, and temperature sensor is used to measuring the real time temperature T ' of indoor environment, wet
Degree sensor is used for the humidity for measuring indoor environment, and VOC sensors are used to measure the VOC content in indoor environment.Exhaust system
Exhaust air rate is controlled according to the VOC content measured, the VOC content of interior is reached the target content of setting, supply air system
Air output is controlled according to the humidity measured, indoor humidity is reached the target humidity of setting.
Air volumematching unit is comparator in the present embodiment, and it is used to compare exhaust system and the exhaust air rate of supply air system
And air output, so that controller adjusts exhaust air rate or air output according to comparative result, reach the balance of exhaust air rate and air output, from
And maintain indoor air pressure balance.Specifically, when exhaust air rate is more than air output, controller control supply air system increase is sent
Air quantity so that air output and exhaust air rate it is in the same size；When exhaust air rate is less than air output, controller control exhaust system increase
Exhaust air rate so that exhaust air rate and air output it is in the same size.Exhaust air rate and air output it is in the same size after, controller is according to row
Wind system and the air quantity Q that changes of supply air system calculate equivalent environment temperature loss △ T (△ T=-KQ, wherein K are constant), then
Temperature control system adjusting ambient temperature is controlled to mesh according to target temperature T and measured real time temperature T ' (△ T=T-T ')
Mark temperature T.In the present embodiment, temperature control system can include some radiators and/or air-conditioning system.When temperature control system
The work of temperature control system need to be constantly corrected during adjusting ambient temperature of uniting using the real time temperature T ' that temperature sensor measures
Make state, so as to accurately adjust environment temperature to target temperature T.Specifically, temperature control system is first thick by environment temperature
It is adjusted near target temperature T, environment temperature is fine tuning to target temperature T further according to the real time temperature that temperature sensor measures.
In addition, as shown in figure 1, the present invention also provides a kind of environment control method, it comprises the following steps：According to indoor ring
The humidity in border adjusts indoor air output to reduce the humidity in environment；VOC content in environment adjusts outside row
Air quantity is to reduce the VOC content in environment；Compare the size of exhaust air rate and air output, when exhaust air rate is more than air output, increase
Air output so that air output and exhaust air rate it is in the same size, when exhaust air rate is less than air output, increase exhaust air rate is so that exhaust air rate
It is in the same size with air output；Equivalent environment temperature loss △ T (△ T=- are calculated according to the air quantity Q that changes of air draft and air-supply
KQ, wherein K are constant, and Q is to change air quantity)；Real time temperature T ' in measuring environment；△ T, real time temperature are lost according to environment temperature
T ' and target temperature T adjusting ambients temperature are to target temperature T.For example, when reaching the exhaust air rate that target VOC content needs 2L, reach
When 3L air output is needed to target humidity, increase the size of exhaust air rate so that it becomes 3L and make the size of exhaust air rate and air output
Unanimously, so as to maintain room pressure to balance, while VOC content and humidity also meet to require.
As shown in Fig. 2 equivalent environment temperature damage is calculated according to the air volume meter that changes of air draft and air-supply because controller shifts to an earlier date
△ T are consumed, the temperature change in environment is judged in advance, and △ T, real time temperature T ' and target temperature T are lost according to environment temperature
The temperature come in adjusting ambient is to target temperature T, therefore the temperature control of the indoor environmental condition control system and control method of the present invention
System response is sensitive, and the temperature fluctuation in environment is small, and temperature variation curve is more steady.It is additionally, since in real-time monitoring of environmental
VOC content, and exhaust air rate is controlled according to VOC content, it is achieved that the control of energy consumption.Simultaneously as in real time in monitoring of environmental
Humidity, and according to humid control air output, it is achieved that effective control to air output.
