[Info on how to calculate chiller capacity]

Got this off from this link.

http://aquascape-aquarium.blogspot.com/2011/04/how-to-calculate-water-chillers.html

The following is a general calculation method to choose the aquarium chillers (heat factor of the lights and pump ignored before). Please note earlier, to cool water 1°C increments of 1 liter in 1 hour needed 4 Btu (British thermal units).

For example, 1000 liters aquarium - initially water temperature is 30 ° C, and the desired temperature is 25 ° C. So it takes 1000 liters x 4 Btu x (30 - 25 ° C) = 20,000 Btu.

If we use ½ HP chiller capacity (about 5000 Btu), the water chillers will run for 20.000/5.000 Btu = 4 hours. Furthermore, after the temperature reaches 25 ° C, the chiller will stop (not working) and start again at a temperature of 26 ° C (+1 ° C). After that, the time needed to lower the temperature into 25 ° C return is 1 hour.

If we use an aquarium chiller with a larger capacity, eg, 1 HP (about 9,000 Btu), then the time needed of the 1 HP chillers to work is a half of the working hours of ½ HP chillers

Conversely, if we use water chillers for aquarium with capacity less than ½ HP, then the time required for chiller to work become longer. This is what causes the chiller rapidly damaged due to lack of resources or working continuously without stopping.

Thank you...very informative

Sorry, hv to repost again as my comments didn't appear separately.

Hey, young punk, i take offence with yr above statement!

My initial offer of help was on Sat only but having seen how AT sweating it out and lamenting that all other volunteers did not show up, i came again on Sun.

So are u saying that the rest of the volunteers are kaypoh/busybody?

Perhaps those who volunteered but didn't show up should borrow yr excuse " slipped my mind....."

Luckily i'm earning close to a peanut.

It seems like u r still a long way off so pls stop passing sarcastic remarks on volunteers like us who sacrificed 2 weekends as " having nothing else really important for you to let go and be at aquarama all the time"

Fyi, i managed to go round n take a look only 1 hr before the exhibition closed.

I would like to apologise to all for my strongly worded reply.

Was real hot yesterday as something happened which resulted in a loss of 140k.

Anyway, that's no excuse for posting that reply.

My sincere apologies

Perhaps those who volunteered but didn't show up should borrow yr excuse " slipped my mind....."

Just can't get enough of this specimen!!! :wub:

looks like i'll restart my hobby soon

Ok, here's the latest game plan.

Basically, the Trade Days do not necesitate the presence of any one from SRC permanently there at the booth as the trade visitors are out to look at equipment, negotiate deals, find new customers etc.

Therefore, all SRC volunteers will be deployed during PUBLIC DAYS only.

This year is slightly easier as we do not have to display sponsor's products, manage inventory and cashbox.

We will need volunteers to help man the booth with a mininal presence where the interested public will be handed brochures promoting the Reef Club and our interests to help them progress in the hobby.

Newbies can come to the booth and speak to more experienced hobbyists. Sunday afternoon, Mr Anthony Calfo will be present so we can do a mini-Q&A at our booth even!

We should give our SRC booth a festive atmosphere... we have a table and chairs, we can sit down for drinks, chit-chat etc.

We will have a timetable of volunteers so at ALL TIMES, we must have at least 3 people around as 'on duty' and the rest can be the 'crowd'.

So here goes! Add in your names!

Sat

1 to 3pm:flyer

3 to 5pm:flyer

5 to 8pm : (help secure booth)

Sun

10 to 12noon:

12pm to 2pm:

2pm to 4pm:

4pm to 5pm: (Speech time need people to STAY at booth)

5pm to 8pm :(more volunteers to help teardown and pack away stuff)

Those who can volunteer the longest till the end of the day will be appointed IC and will be given a TRADE PASS for free entry and massage by Diabolus.

i can man the booth from 1 - 5pm on sat.

after 5 i'll go look see look see

Sorry folks, been very very busy... last few weeksn and next week is kinda hell for me (what an understatement).

I've been settling the sponsorship for Anthony Calfo seminar and the SRC booth setup as a priority.

Still sorting out my first batch of volunteers workers...

i can man the booth on fri and sat

[Help make SRC@Aquarama05 a success again!]

AT,

Shouldn't we call a meeting for all volunteers to tie things up before the show?

[Help make SRC@Aquarama05 a success again!]

I can help to man the booth

[Help make SRC@Aquarama05 a success again!]

I can help on 1 weekday n 1 weekend

Very very nice!

I'm impressed!
