Chiller HP Conversion Table - Watts against HP

[hamannbmw]

Finally got the conversion table

Can someone based on the example to guide me how to convert

eg.

1. Tank 4 X 2 X 2 1/4

2. Sump 3 X 1.5 X 1.5

3. Light 2 X 250watts

4. pump 2 X 80 watts

Here is the table :

[(total water vol in us gal X 8.3lbs/gal) X 18 degrees fahrenheit

-----------------------------------------------------------------------

24 hours

+

(total heat given by equipment (watts) X 3.413)] X 1.2

=

??? BTU/hour

---------------

12,000 BTU/hour

=

??? HP OF CHILLER

Can those Math genius help me.....

Hope this table is beneficial to all...

Hope its not too confusing.... the line is actually DIVIDE

[hamannbmw]

no one knows ?????

I didnt calculate..

But should be 1 HP chiller is more than enough.

Min 1/2 HP.

tk vol=4x2x2 1/4=18cubft=134.65us gal

sump vol=3x1.5x1.5=6.75cubft=50.5us gal

[(134.65+6.75)x8.3]x18

---------------------------- + {[(500+160)x3.413]x1.2}

24

880.22+2703.1=3583.32/12000=0.29

1/2 HP!!

[hamannbmw]

880.22+2703.1=3583.32/12000=0.29

1/2 HP!!

0.29 = 1/2 HP , care to explain

1/2 HP roughly equates to 373W and 1273BTU/hour.

[hamannbmw]

1/2 HP roughly equates to 373W and 1273BTU/hour.

meaning ???, sorry i'm still confused

[lightningstrike]

meaning ???, sorry i'm still confused

this means a 1/2 HP rating will give u roughly 373W of power.

it oso means 1273 BTU/hr = 1/2 HP.

[alvy]

eh..i tot 1 HP is already 12000BTU??

[hamannbmw]

this means a 1/2 HP rating will give u roughly 373W of power.

it oso means 1273 BTU/hr = 1/2 HP.

But based on tdmrider it should less than 1/2 Hp right ? since it end up only = 0.29 instead of 0.50

If u based on tdmrider BTU column is 3583.32 and if u r saying 1273 BTU/Hr = 1/2 HP , den 3583.32 BTU/Hr will be 1.4HP ????

Hi all,

I derived at 1/2 hp was b cos it was calculated 2 b 0.29. At 0.25, it shd b a 1/4hp. but since the answer has gone beyond this value, it will b adviseable 2 get a 1/2hp.
