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

Answer / sathish kumar

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.

Answer / virendra joshi

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
