Installation example
The information in this page are only a partial and summary statement of the real project.
The purpose of this text is only to provide a rough track.


Reference project:  C 1456 date 3-9-2001

Plant of 1.400.000 m3/h divided in 7 air conditioning units, for a synthetic textile manufacturing plant in IRAN.

 

PURPOSE OF THE PLANT

Brief description of the components

The process air after having stabilized yarns (Quenching) and conditioned (Take-up), it is partly taken from the axial through vents positioned in an intake manifold at the top of the room and partly expelled from the Torrini expulsion sites on the roof of the department (this amount of air expelled is always replenished with outside air).
The air in the subject which for convenience we will call-back, is piped to a trio of roller shutters and there will be either expelled and reinstated with outdoor air or recirculated.
The trio of dampers receives commands from a microprocessor that analyzes the characteristics of the air detected by a temperature probe placed in front of the washer.
At this point the air undergoes a first filtration means of rotating filters and is then conveyed in the washer where it is a treatment of adiabatic humidification.
From here on is divided into two parts, since it must go to the service of two distinct areas precisely Quenching and Take-up.

Quenching air service.

After being wetted by the washer is so treated:

1) cooled and dehumidified by cooling coil,
2) and conveyed through inlet centrifugal fans,
3) heated by heating batteries,
4) Filtered finely filters high degree of filtration,
5) Adjust pressure through the shutters of surplus.

1) The cooling coil control valves are controlled via three-way pneumatic receiving impulses from the microprocessors that analyze the characteristics of the air detected by the probes of moisture placed after the treatments 1 / 2 / 3 / 4.

2) The centrifugal fans are likely to provide the air needed to operate the same prevalence of the spinning process.

3) The battery heater control valves are controlled via two-way pneumatic receiving impulses from the microprocessors that analyze the characteristics of the air detected by temperature sensors placed after the treatments 1 / 2 / 3 / 4.

4) The filters have a pressure gauge that allows the U-valued when they replace.

5) The surplus dampers are controlled by pneumatic pistons which receive impulses from the microprocessors that analyze the air pressure detected by pressure from probes placed after the treatments 1 / 2 / 3 / 4.

At this point the air is piped to the process machines NEUMAG.

Air service to Take-up.

After being wetted by the washer is so treated:

1) cooled and dehumidified by cooling coil,
2) heated by heating batteries,
3) and conveyed through axial inlet.

1) The cooling coil control valves are controlled via three-way pneumatic receiving impulses from the microprocessors that analyze the characteristics of the air detected by the probes of moisture placed after the treatments 1 / 2.

2) The batteries of heating are controlled by pneumatic control valves, two-way receiving the pulse from the microprocessor that analyzes the characteristics of the air temperature detected by the probes placed after the treatments 1 / 2.

3) The axial fans are likely to provide the required air distribution mainly in the Take-up.
