Chiller Running Overtime

[weileong]

My tank only 800l you want me to go for 1hp? Already max capacity at 800l, no more upgrading unless I move house.

Actually before that was thinking of the 1hp but later I count my dollar notes think consumption too high.

Are you going to 1hp? Polar bear will reproduce in your tank

Weileong, i desperately need the chiller cos the whole house is as hot as hell. the compressor runs non-stop trying to cope with my MHs and it heats up the house. Chiller is also burning hot to the touch. Very dangerous i think so better be quick to remove the potential fire hazard or overheating problems that might trip my tank...

so in this case... good things better happen fast.. the faster the better in my case. hehe

1hp is about 12 000BTU

if you see your aircon is 12 000BTU...means running your aircon of 12 000 BTU is about the same consumption as a 1hp chiller for the same runtime....thats just a very coarse estimation, real consumption may be way off, me not electrical expert

[weileong]

Wow sounds like really desperate case. I would do the same if I were you. My existing chiller is not so hot. I can still put my legs on it and not get burn

Give some feedback after your chiller is installed okie?

seriously thinking of it if i wanna upgrade chiller...

my current teco 1/2hp can sustain my 27deg set temp....so if i end up wanna change, no point buying another 1/2 hp that can sustain 27 set temperature right?

either change to 1hp or dun change and continue with my teco lor

[weileong]

Errmmm... the cooling power is different

The TW6 can't even chill my tank with all my MH, pumps running

Don't read too much into the HP rating, sometime no so accurate and you gotta be sure what you paid for is what you get

[AlfaRomeo]

Weileong, i think i know what you mean. yup, better be sure what you are paying is what you are getting. The terminology used can get very confusing.

[weileong]

The same applies to TECO too (at least for the TW6) Don't believe go check it out properly.

[roidan]

true also...

but like i said lor...unless my teco work all the time until cannot keep at 27 then really have to change liao....

comparing 1/2 hp from chiller to chiller will have varying performance also..

1/2hp atman to 1/2 RR to 1/2 TR to 1/2 Teco to 1/2 artica to 1/2 haliea chiller...all numbers....but actual performance in practical use differs....

even same models may have different performance due to operating environment differences, and with such ambient sensitive equipment like chillers, may differ alot....

i still marvel how my 1/2hp teco can keep my 6ft tank, 5ft sump and 2ft clam tank at set temperature...and all my pumps are internal...i never ran those pumps externally...hehe

i am sure the 1/2hp artica can do as well or most probably even better than my current teco at keeping my set temperature, but if i really wanna change chiller, i seriously think i should go for the 1hp...hehe....

that's my view based on my tank conditions so far

artica 1hp, here i come after my teco gets faulty

artica artica, bring me to anthartica

[roidan]

anyway, who is the agent of artica chillers ah...must ask him to be a sponsor here also....like the RR/TR, then we got more range to choose from...

here's another pic of artica information for the non aircon-lookalike models....

seems like i am the agent hor ......hahaa...not me lah...

ps: mr agent, remember to give me discount when i get my 1hp artica

[weileong]

Use 220v brochure better

[roidan]

haha..yeah hor....

make sure u insist on your discount on monday

[weileong]

For commerical chiller (aircon look alike)

[weileong]

Ah... see the specs properly and you do the maths.

For DA-500B, 1/2hp consumption is 2.8A 230W = 644W but rating says 1170W probably referring to cooling power?

Then DBM-250 1/3hp consumption is 3.5A 230W = 805W but rating say 1000W probably also referring to cooling power.

Actually makes sense since the commerical chillers have strong exhaust fan and hence more efficient.

So don't just look at the paper specs, gotta check it out in details if avaliable.

[AlfaRomeo]

In the brochure, the 1/2 Hp is for 500L tank only? sure or not...

[weileong]

500L because it is kept at 15 degs C For lobster you see ????

You don't keep lobster or pengiuns right? Maybe keep penguins need 3hp one for your tank.

[Maxima]

a stupid question....

monthly how much issit (electricity bills) roughly to run a 1/2hp chiller? issit much much lesser than running air-con 24/7??

A REAL 1.5HP that has 20,000BTU or so running frequently (frequently is NOT NON-STOP) will amount up to $70~$90 a month. That's a very brief estimate base on a 8ft tank set at 27 degree, delta of 1 degree.

Max

[AlfaRomeo]

I tot of putting in polar bear, considering its diet now.. hehe

[roidan]

actually does artica publish the cooling graph ah?

of coz the cooling graph doesnt consider pumps, lights and takes ideal working conditions...

but at least just a rough idea will do also

[weileong]

RA680 rating is 400W abt 1/2hp cooling power. This chart does not take into consideration the heat load from pump, lights etc.

Weileong,

The diff is actually the refrigerant use. Arctica tower design uses R134a refrigerant while Arctica commercial uses R22 refrigerant. R134a refrigerant is the replacement to R22 refrigerant becoz the later is environmental unfriendly.

The size of compressor to drive R134a is bigger as it required higher working pressure as compared to R22 refrigerant. Therefore a 1/3HP R134a refrigerant compressor will consume more power than a 1/2HP R22 refrigerant compressor...

wah...very steady info..

where is our resident aircon expert? bro lightningstrike right?

[Hon]

In the brochure, the 1/2 Hp is for 500L tank only? sure or not...

hey bro, it's say 1/2HP for 500L at 15 deg C. You missed the fine print below

[weileong]

Heng ah... I choose the commerical one! Who cares abt environmental friendly or not.

But come to think abt it, you get the 1/3hp that consumes more power, you're just transferring more air pollution to the power station.

R22 not ozone friendly nevermind, the small compressor don't use so much coolant

Opps I not supposed to talk like this as I always have to tell my customer to be enviromentally friendly.

Oh ok...makes sense now. threw me on a curve after reading that..in that case, to infinity and beyond...
