0. Introduction & Promising Effects''Humidity control'' is
the essential requirement for static or moisture issues and stable
operation in textile industries.Because moderate humidity provides
ideal environment so that static electricity hardly generate and
moisuture without wetting.Ikeuchi's AirAKI Dry Fog Humidification
System will provide uniform stable humidity.Ikeuchi would like to
offer the following proposal for your benefits of productivity,
quality.
1. Conditions
Approx. Volume [m3] 49,896
Measurement [m] 84 x 108 x 5.5
Target Temp. & Humidity 70%RH at 22 deg C
Worst Temp & Humidity -
Supply Air [m3/hr] N/AWorst Outside Air Conditions 8 deg C, 50%
RH
Absolude humidity [kg/kg (DA)] 0.0033
Outside Air Induction [m3/hr] * 49,896
Ventilation rate [times/hr] * 1.0
* We assumed these numbers.
2. Humidity CalculationOur humidity calculation resulted 178
nozzles at least would be required to get the target
humidityconsidering the above air conditions.
Target Humidity
70% RH at 22deg C Desired Humidity [LPH] 497
Absolude humidity [kg/kg (DA)] Desired Humidity [GPH] 131
Quantity of Nozzles(Calculation Result)
if only 6,003LPM at 0.3MPa air can besupplied. 207
0.0116
Quantity of Nozzles(Calculation Result)
if 5,934LPM at 0.5MPa air can besupplied. 138
3. Humidification System Layout and UtilityWe would like to
propose our humidification system using 140 nozzles considering
layout balance. Please check the utility below and the attached
system layout.

Refer to the attached layout and ''Break-down of Dry Fog
Humidification System Proposal''.
Option: Quote No.901204This is the quote of humidifiers only
without controller when you prepare humidity controllers, solenoid
valve units, humidity sensors by yourself.
3) Supply by customer or third-party contractorQuantity
Remarks
Plumbing and InstallationStainless steel pipes, valves and
fittingsPlumbing, Components installation 1pkg.Power distribution
works, Pipe flushing before system start-up
General Installation manualto be provided by IKEUCHI.
You may need some stop plugs to adjust spray nozzlenumbers or
when you maintain nozzles.
Pressure: 0.3 - 0.35 MPa (44-51PSI) at a point of
useTemperature: 5 deg C (41 deg F) - Normal temperatureQuality: Air
without moisture, oil mist and dust; Dew point 10 deg C (= 50
degF)Purifying Devices: Air Dryer, Air Filter, Oil Filter
* Air Filter - Remove foreign particles of over 5 micro
meter.Oil Filter - Remove foreign particles of over 0.03 micro
meter.
Air Heater: Place an air heater when the humidifier is operated
in low ambient temperature orwhen the compressed air temperature
becomes lower than 12 degC (=54 degF)* Apply thermal insulator to
air pipe after the point of an air heater.
Pressure: 0.1 - 0.15 MPa (15 - 22PSI) at a point of
useTemperature: Normal temperatureQuality: No particles
Electric Conductivity = 0.07 - 10 microsiemens/cm(Resistance 14
- 0.1 M ohm/cm )Silica ( SiO2) = 5ppm or less
Total Hardness + Bicarbonate = 60 ppm or lessPurifying Devices:
Y Strainer(0.1mm), Water Filiter (5 micrometer), Water softner
Reverse Osmosis Water Purifier, Ion Exchange Water Purifier*
Water Softener and Reverse Osmosis Water Purifier produce
continuousdischarged water during their operation. Provide drainage
basin.
Remarks4 nozzles mounted.Inelt connections of air and water are
1/4'' NPT femalethread. Refernce drawing and image of intallation
areattached.
Humidifier2 nozzles mounted.Inelt connections of air and water
are 1/4'' NPT femalethread.

5. Typical System Flow
We will supply No. 1 - 4.Please check No. 5 - 9 (10) & No.
11 - 17 are already installed.
6. Maintenance
Daily check- Spray pattern of Humidifiers- Air pressure and
water pressure- Drain water volume of air filter- ON/OFF control by
the solenoid valve and the cotroller is working
correctlyPeriodicalMaintain air compressor, reverese osmosis system
and deionizer regulary
Off-seasonDrain water in pipe, water tank when you don't use the
system over a few days in summer time, 1 week in winter time.
