Answer / nilantha warushavithana
1 TR = 12,000 BTU/h
1 BTU/sec = 1.055 kW
12,000 Btu/h = 3.5166 kW
1 kW = 3412.3 BTU/h

Ikw
Power input in kw for per ton of refrigeration KW/TR
FOR EXAMPLE 100TR CHILLER
FOR PRODUCING 100TR POWER CONSUMED 90 KW
IKW /TON = 100 / 90 = 0.9 i.e 0.9 KW /TON
to find IKW,COP,EER
If the power consumption is 1 kw /ton power consumption
system will provide cop of 3.5 and EER will be 12.

In general Practice you can consider 1 Tr = 1200 Watt = 1.2
kw
1 TR = 3.5 KW is next to impossible.

Answer / sohal
to find out ikw
Amp.X Volts X Power-factor X 1.732/1000= kilowatts
then divided by machine tonnage = input kilowatt(IKW)

Answer / sandip bharne
1Tr=80x907/24 ( ice requires 80kcal/hr to melt,907 is US
short ton)
=3023 Kcal
1kw= 860kcal/hr
1TR =3024/860
1TR =3.51KW

Answer / carol
Be Carefull!!!!
TR and W are POWER UNITS
Btu is an ENERGY UNIT
As everyone knows from Basic Physics:
Energy = Power x time
The actual conversions are:
12.000 Btu/h = 1 TR
1 TR = 3517 W
Therefore,
12.000 Btu = 1 TR-h
12.000 Btu = 3517 kWh
Watchout!!!!!.....

Answer / shri narayan gond
I know that 1 kw = 3413 B.T.U. and 1T.R.=12000 B.T.U. ,1T.R.=12000/3413.=3•5Kw.
Santiry fugle chiller I.K.W.=lode k.w./T.r.
For ex. My chiller capacity is 760 tr. And lode
509 kw.
I.K.W. =509/760
Ikw =0•669

Answer / pradip
1TR= 12000BTU = 3000KCAL = 3.516KW,It is a thermal Unit,
But IKW relate of Power Consuption of Kw/TR,
In market many HVAC systems area available,so every systems
has different IKW,
Example : for VRV system
1TR consume 0.95 to 1.2KW,
1TR=1.2KW,
so IKW =1.2

Answer / ruka
1TR=3.5kW <-- Cooling Capacity
3.5kW/COP = Electricity Consumption; normally COP>= 3
COP = Coefficient of Performance
If COP = 3.5
then;
1TR = 1kW <--- Can be varie

Hi, We facing one similar problem in our computers i.e we are newly constructed our design department after that shifted our computers but our computer desktop screen is vibrating. we are conducted our electrical maintainance person he told that is UPS problem, then we changed the UPS also again we are facing that problem in that room only. then we put lcd monitors that problem is solved. But in other monitors why the computer desktop screen is vibrating please give a suggestion to me. Regards, Raju.N.G
