Question on Equipment Specs

Question on Equipment Specs

Question on Equipment Specs

(OP)
I have the spec sheet from a sanyo split cooling system , and am a bit confused as far as the power input specification:

"Cooling Capacity (BTU/h): 17,500(4,000-17,500)
Power Input         (W)  : 1500/1500(250-1500)"

(http://www.sanyohvac.com/products.php?id=18KS72_18KLS72)

I'm assuming the 1500W is for peak @ 17,500BTU/h and the 250W is for the 4000BTU/h operating capacity??

Similarly, on ceiling mounted units,

"Cooling Capacity (BTU/h): 39,000(9,500-39,000)
Power Input         (W)  : 3890/3830"
(http://www.sanyohvac.com/products.php?id=42TW72R)

and my assumption doesn't seem to hold in this case?? or are the two numbers representing inside unit and outside unit (evaporator/condenser unit)
what am I missing here?

TIA,


 

RE: Question on Equipment Specs

Is this part of the specs?  (Sanyo split system ductless AC, 17000 BTUH)

♦ Power Supply Voltage/Phase/Hz: 230/208V / 1PH / 60Hz
♦ Running AMPS (Cooling) : 7/7.7 (1.2⇔7.7) Variable Speed
♦ Fuse or Circuit Breaker Capacity: 20

If so, your max power is approx 4.6 KW assuming 100% power factor.

how do you come to the 4.6kW max power? why is that number different than the "power input" and what about the ceiling mounted unit which is a 39,000BTUH unit? sorry for all the questions, I'm a bit confused, and thanks for your help

RE: Question on Equipment Specs

Assuming 100% power factor, watts = volts x amps = 230 x 20 = 4600 (Maximum)  Actual running kw is about 230 x 7.7 =1771 watts.

RE: Question on Equipment Specs

Anoying indeed to have a manufacturer publish performance data for the electrician and not for the engineer.
The solution in such cases: Change manufacturer. Try Mitsubishi, they will give you the nice data that you need.
