Centre controller unit control spraying cooling section and/or steam heating segment adjust air.
As between spinning, the regulation of humidity is more important than temperature adjustment, and as the coupling of temperature and humidity is closed
System, so the regulation of temperature and humidity will be combined carrying out, when humidity between spinning is adjusted, indoor temperature can be with humidity
Increase and lower the temperature, heat up with the reduction of humidity.In regulation process, feeding spraying pump 13 is mainly used in humidifying air, condenser pump 6
It is mainly used in carrying out dehumidifying and cooling to room air.
According to the difference in season, regulation and control method is different, is broadly divided into following 3 kinds of situations：
1) summer：Using 6 spray process of feeding spraying pump and condenser pump.
For the control of humidity between spinning, when humidity is less than setting value between spinning, first adjusts air draft and adjust window 1, fresh air
Adjust window 2 and return air adjusts the aperture of window 3, need the increase wherein big air quantity of water capacity；When the value of X exceeds 15～85 scope
When, central controller unit increases the frequency of feeding spraying pump 13 again, and increases the frequency of pressure fan 10；When indoor humidity is higher than to set
During definite value, first adjust air draft and adjust the aperture that window 1, fresh air adjusts window 2 and return air regulation window 3, reduce the wherein big wind of water capacity
Amount；When the value of X is beyond 15～85 scope, reduces the frequency of feeding spraying pump 13, reduce the frequency of pressure fan 10.
On the basis of humidity requirement is met, when between spinning, indoor temperature is less than dew point temperature, condenser pump 6 stops fortune
OK, central controller unit control increasing exhaust adjusts the aperture that window 1, fresh air adjusts window 2, reduces the aperture that return air adjusts window 3,
Indoor temperature is made to be raised to naturally dew point temperature；When between spinning, indoor temperature is higher than dew point temperature, control air draft adjusts window 1 and new
Wind adjusts 2 aperture≤15% of window, and return air adjusts aperture >=85% of window 3, opens cooling regulating valve 7, opens condenser pump 6 and board-like
Heat exchanger 16, sprays the mixing water cooling of chilled water and shower water by shower nozzle 18, until indoor temperature reaches design temperature.
2) spring and autumn transition season：Referring especially to the regulation and control method of summer, cooling regulating valve 7 is closed, that is, close chilled water and enter
Water valve, using 6 spray process of feeding spraying pump 13 and condenser pump.
For the control of humidity between spinning, when humidity is less than setting value between spinning, first adjusts air draft and adjust window 1, fresh air
Adjust window 2 and return air adjusts the aperture of window 3, need the increase wherein big air quantity of water capacity；When the value of X exceeds 15～85 scope
When, central controller unit increases the frequency of feeding spraying pump 13 and condenser pump 6 again, and increases the frequency of pressure fan 10；Work as interior
When humidity is higher than setting value, first adjusts air draft and adjust the aperture that window 1, fresh air adjusts window 2 and return air regulation window 3, reduction wherein contains
The big air quantity of moisture；When the value of X is beyond 15～85 scope, reduces the frequency of feeding spraying pump 13, reduce the frequency of pressure fan 10
Rate.
