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

What is principal to reduce earth leakage current with isolation transformer? When isolation transformer is installed in input stage of system, earth leakage current is reduced. the reason is why the leakage current of 2nd stage of isolation transformer does not affect the 1st stage's leakage current. I would like to know the reason. As you know, earth leakage current is a kind of AC. So, How to reduce earth leakage current in case that isolation transformer is used?
