Resun 650

[gods_angel77]

I’ve been using the Resun650 for about 3 months now

Here is some feedback and information for you guys

When the new Resun 650 chiller cut in and out it’s extremely noisy

the compressor cut in/out every 10min creating a loud bang sound each time the compressor kicks in/out.

My chiller set temperature is 25 deg c it cut in almost 6 times in 1 hour & 144 times a day. Who ever tells me it cut in only after 1 hour must be joking.

Overall the unit can be improve on

I believe the compressor should use inverter technology to save

cost and i strongly don't think that the bill only increases by $10 per month it is definitely range between $50-$60 per month.

If I have the money I rather pay more to get a better quality chiller like arctica

Anyone who wants to feedback to me can E-mail me at gods_angel77@hotmail.com

I doubt your statement of electric bill of $50-60 a month for CL650. From my simple calculation.....

CL650 = 0.25hp = 187 watts

187watts * 24 hrs = 4.488kwatt/hr

What is the HDB electric charges? I think is around 0.158 $/kWh

Therefore, 4.488*0.158 = 0.71 cents per day. Take this multiple by 30 days give you only $21.27. Is there anything I miss out?

[roidan]

as far as i know...

the CL650 states 650W

here u go...

[kareen]

Really What you get that figure from? I thought it is just a 0.25hp chiller. 600 over watt is equilvalent to a 0.8hp chiller.

[roidan]

actually there's alot of confusion over chiller ratings....even myself also not too sure...

anyway, the best is to test the live/neutral chiller wire with a clampmeter and definitely get the amperage and thus the consumption

[kareen]

u mean the refrigerating capacity? Hm..... I thought the horsepower is the electrical rating..... I really cannot believe it

[roidan]

yeah lor...

take for example...

teco 680/tw6 which is rated 1/2 hp...draws 420W

artica commercial 1/2 hp ...draws 600+ W

maybe can ask lightningstrike or cookiemonster to clarify for us how come all these numbers like dat...hehe

[kareen]

That will be very nice......

BTW, did you use a clameter to take a CL650 before? A 0.25hp draws 600watts sound way out..... I doubt they can get their ISO standard if the case.

[roidan]

did not lor...

but if any bros willing to expose their CL650 live/neutral wire out for me...i dun mind measuring for them if i am around their area.

[kareen]

hee..hee... I am using one model smaller one and I lived in Tiong Bahru area..... How?

Usage Charge

(w.e.f. 1 Jan 2005)

16.73¢/kWh

from singapore power web site

therefor 4.4880kw*16.73= $75.08

[roidan]

wah.....lol

dun have sengkang/punggol ones ah...

i know gouldian may be getting a CL650....if he allows to strip the wire to test then can find out liao....but stripping the wire quite ugly lah....lol (may affect resale value too )

hope lightningstrike from his personal experience with chilling systems or cookiemonster as rep for pacific coo can enlighten us with all these numbers...

then we no need perform operation on our chiller wires hehe

[kareen]

4.880kwatts * $0.1673 = $0.75 per day multiply by 30 = $22.52..... I believe.

[kareen]

Hi roidan!

That's okay lah..... looks like gods_angel77 make a mistake in his calculation.....

[gods_angel77]

pls lah you don't need to strip any wire form yr chiller lah

just off everything in your home expect leave yr chiller on go to yr pub electric meter located out side of your house than you can measure the amp already mah tong yr Amp meter on the red wire Hor ok

[lightningstrike]

i hv posted calculations for true comp mechanical power rating (H.P) in a previous thread as shown. hopefully it will clear ur doubts.

http://www.sgreefclub.com/forum/index.php?...3044&hl=danfoss

btw kareen, a chiller does not run 24hrs a day. it wld be more logical to assume 1/2 of that. true running time will hv to be dependant on quite a few factors, e.g. ambient temp, placement of chiller, pump flow thru rate to chiller, etc.

[kareen]

Hi Lightingstrike,

Yes, I know that. Even my worst case scenio also cannot get $75 bill mah.

[gods_angel77]

will get back to you guys on the actual cost calculation not free to do it now so if i made a mistake a big apology on that but i believe the cost is still very high when compare to and inveter compessor

Chees.

kareen staying in tiong bahru? which part?

haha, i m another reefer in tiong bahru too

Hello gods_angel77,

Yes, I definitely believe the running cost is high.... ie imagine the $20 bill is for your fish only on chiller not including MH, pumps, etc. But not as high as your 1st statement of $50-60 bill on CL650 per month.

Also, I am not picking on you, just point out your mistake so that others don't blindly agree. I may have overlook something and I welcome people point it out so that I learn.

Opposite the temp. tiong bahru market. How about you?

[Gouldian]

wah.....lol

NVM if I can gaurantee a Teco @ a lower price .....

I've tried to monitor the power comsumption from the day i started using my 250w MH,Resun CL650 and the rest of the PHs. This is my "not so accurate' findings.

Total increase of Electricity bill on a 3 mths average - $50

250w MH @ 8 hrs/day - $0.35 per day/$10.50 per month

160w of Powerheads @ 24 hrs/day - $0.65 per day/$19.50 per month

Therefore Resun Cl650 - $0.70 per day/$21.00 per month

BTW, the temp on my chiller is set at 26 degrees celcius and my chiller kicks in once it reaches 28 degrees celcius.

My chiller kicks in once every 1 and 1/2 hours and for about 20 minutes each time.

It might not be accurate but i hope that it provides a rough guide on the power consumption of the CL650.

cheers!

Bro Diabolus,

Do you find that your chiller is producing the sound discribe by gods_angel77?

I getting worried now......

[diabolus]

I got my chiller 2nd hand from another reefer.

its 1 yr and 4 mths old now.

compared to other CL650 ive seen, the sound is still very quiet when its kicking in and the only loud noise is when it stops.

otherwise, i think i got myself a very good set considering the price i got it at and the age of the chiller.
