We help in creating amenity environment bothfor district air and heat center and industrial factory

Cross flow typeWann water that flows back to cooling tower

will naturally flows from upper warm water tankto the fill material parts by sprinkle. This warmwater wfll contact at right angle with the air whichis suck in by a fan through louver. Part of the waterwill evaporate and loss its lateJ:}t heat. The waterwhich is cool down in this way will again be suppliedto each equipment from the lower part of coolingtower. Wann air will flow up and out to the atmosphereby the fan.

4. It Is ease to be used as a district air andheat center or industrial factory cooling tower.

3. When equip with adry resin heat exchangerin the tower enable it to act as an auto smokepreventing tower.

2. Succeed In new design make the equipment'lighter, t:esln Is used In some parts includinganti rust treatment making the life last longer.

:1.-4 lrilling

The newly developed filling for the cross-flow type cooling tower is membrane

filling having excellent performance, and can withstands many years of

service because of the use of rigid PVC excelling in weather resistance.

1-5 Fait

The alumioum-made axial fan has a variable structure whereby the ~lade angle

can be freely adjusted. It is extremely lightweight, and excels in corrosion

resistance.

'It is made with highly waterproof specifications 'for the cooling tower.

:I. -5 Speed ",,,duoer

The a~is-orth090nal two-stage type designed and manufactured exclusively

for the cooling tower has been adopted. All gears in use are helical gears

and spiral bevel gears with hardened tooth flanks, heeding adequate strength

and quiet operation.

In addition, due to the original oil dam structure adopted at the top of

the housing. the upper bearing is also lubricated with oil, requiring no

grease filling, so that maintenance man-hour'! are reduced.

1-7 Drive shaft

:rhe drive shaft that transmits rotations of the motor to the speed reducer

has an extremely simple structure, in which two hubs, one center ring and

two pairs of disk packs are coupled with several reamer bolts, requiring

no lubrication because the components have no friction parts.

Also, since each member is made of SUS, it withstands continuous use "vep

in a lOot hUmidity atmosphere.

Since the corrosion conditions of the casing framework vary depending on

the envi~onment, check for the presence or absence of rust once a year.'

6-8 Circulating wAter

a. Since the circula ting water should basically be pH6. 5 - 8.2, check Eor

mixing of matter that adversely affects the water quality of the

c~rculat~ng water once a month, and immediately remove it if any.

b. Check every day to $ee if the amount of supply water is proper when also

checking the water basin.

6-9 Water quality contro~ ,

Maintenance is indispensable in the ability of the cooling tower to

perform water quality control, inclUding U$e of water treating agents

in cooling water and blow-down as measures to prevent adhesion of scales

and slime to the filling surface, which can be the main factors in

performance deterioration of the cooling tower.

Since the heat exchange in the cooling tower by direct contact between

the air and hot water cleans the air conversely, the water quality of

the circulating wateJ: is gJ:eatly affected by the air around the installed

coolioq tower.

For the cooling water system, total water treatment is required because

problems of scales, slime and corrosion do not ocem: separately but occur

in connection with each other.

If the water contains iron, total hardness components, silica, organic

substances, etc., hard scales of carbonate and silica adhere to the

surface of the heat exchanger due to concentration, reSUlting in

deterioration of the thermal efficiencies of the refrigerator and

condenser.

Tab~e 9-1 shows the proper water quality control standards of coo~ing

water.

Fig. 9-2 shows the relationship between the rate of concentration, amount

of supply water and amount of blow~down.

If the water is not treated with use of Chemical agents, control the

2 . The theoretical formula of a cooling tower

All the intermediary quantity of heat accompanied by substance movement between the waterand air in a cooling tower is proportional to an Enthalpy difference, and is expressed as follows.

Gdh= Ka (hw-h) dY

If movement of all intermediary quantity of heat shall be performed only in tbe evaporationlatent heat of water

3.Quantity-of-heat calculation of a cooling tower

Flux of water L and air flux From G to a water air ratio It asks for N and is numericalintegration. It asks for U/N or U. Next, the filler capacity of a cooling tower is decidedarbitrarily, and if it substitutes for (8) formulas, a required Ka value can be found. Fillerperformance formula obtained by this required Ka value and experiment Kao is compared,and if set to Kao/Ka >= 1, specification will be satisfied on quantity-of-heat calculation.
