 Friends,
 
 Wanted  to  share  a  cheaper  and  sustainable  way  of  keeping  your  tank  cool  for  this  summer  without  using  expensive  chillers..............
 
 Most  of  us  are  aware  that  evaporation  causes  the  temperature  to  drop.  Air  cooler  works  on  the  same  principle.  All  that  needs  to  be  done  is  have  a  normal  pedestal  fan  face  the  tank  just  above  the  water  level  and  let  it  run  at  a  high  speed.  This  causes  good  amount  of  water  to  get  evaporated  from  the  surface  due  to  increased  air  flow.  I  could  see  around  4  liter  of  water  will  get  evaporated  when  running  for  8  hours.  Now  go  an  touch  the  water  surface  and  BINGO  you  are  already  running  your  hands  in  a  cool  water.  I  found  the  fishes  and  plants  loving  it   Smile  .  Now  I  don't  need  to  run  for  chillers  anymore.
 
 -Arun
 
 P.S:   If  you  need  a  picture  for  better  clarity  I  can  attach  that  too.

 Do  you  have  any  Idea  of  the  power  consumption  of  the  Pedestal  fan..?
 I  think,  it  will  be  cheaper  to  install  CPU  or  computer  chassis  fans..  of  course  you  need  to  do  some  DIY  thing  to  connect  and  mount  them  on  the  tank.

 As  mentioned  by  Nidhi,  its  best  to  use  the  computer  fan  or  4"  industrial  axial  fan.  3-4  fans  connected  together  would  be  sufficient  for  a  3  foot  tank.  Based  on  the  tank  size,  you  can  increase  or  decrease  the  number  of  fans  in  the  setup.
 
 4"  axial  fans  can  be  connected  directly  to  230volt  AC  and  it  gives  more  air  than  the  normal  computer  fans.
 
 Pedestal  fans  would  consume  more  electricity...   Thumb Down   Thumb Down

 IMO  efficacy  of  a  pedestal  fan  will  be  many  fold  greater  than  any  of  these,  especially  when  you  are  on  the  top  floor  and  facing  lot  of  radiation.  Yes  agreed  on  the  power  consumption  somewhere  around  55W,  but  then  it  is  not  too  much  for  what  you  are  going  to  end  up  shelling  out  for  an  expensive  chiller.

 Arun,  thats  some  serious  cooling.  Especially  you  being  in  Chennai,  and  considering  its  quite  humid.
 What  temperature  drop  does  it  do?
 
 We  in  dry  places  can  manage  it  by  CPU  fans,  i.e.  get  down  by  few  degrees.  
 So  if  we  keep  efficiency  and  efficacy  aside,  the  lesser  you  burn  the  lesser  you  pay,  thats  what  Nidhi  wants  to  say.

 Hello  Josyjames!
 
 Can  you  please  let  us  know  where  can  we  get  the  4"  axial  fans  that  can  be  connected  directly  to  230volt  AC?  A  pic  or  link  will  be  helpful.  I  wanted  something  that  can  be  directly  connected  to  AC  supply.
 
 Regards
 Agnelo

 Ya,  to  be  precise,  it  is  a  table  fan  with  a  adjustable  stand  (not  really  a  high  power  pedestal).  Sorry  for  the  confusion.  It  was  left  unused  for  long  time  and  was  also  thinking  to  dispose,  but  now  I  guess  I  have  put  it  to  a  good  use.

 You  can  get  the  4"l  fans  that  can  be  connected  directly  to  230volt  AC  in  perambur  (Chennai).  Am  not  sure  about  the  shop  name  but  it  is  near  Sembiam  Police  Station.  Don't  worry  you  can  easily  find  the  shop  -  it  is  a  big  electronic  shop  there.  This  looks  like  a  CPU  fan  of  bigger  size.
