Answer / bhanu mahesh

A ton of cooling capacity is the amount of cooling that
would be provided by melting a ton of ice. Thus, a central
air conditioning system that is rated as a 2-ton system
would provide the same cooling as melting two tons of ice
per day (24-hour period).

Ton vs BTU
A ton is equal to 12,000 BTUs. Thus, a 2-ton air
conditioner is equivalent to a 24,000 BTU air conditioner

Answer / rajan s.k.

It is equivalent to the production of cold at the rate at
which heat is to removed from one US tonne of water at 32 0
F to freeze it to ice at 32 0 F in one day or 24 hours, and
is denoted as TR

Thus


1 TR = (1*2000 lb * 144 But/lb) / 24 hours
= 12,000 Btu/Hr
= 200 Btu/min

Answer / mahesh

1TR-
"The amount heat required to extract from 1000kg of water
to convert it into ice,in 24 hrs from 0 degree water to 0
degree ice.

1TR = (1000Kg * 335kj/kg)/(24*60*60)
= 3.8kw
= 3.5kw

Answer / vikas

It means that a particular device is able to convert 1
tonne of water i.e., 1 lts. into ice in 24 hrs. (at ideal
conditions).

Answer / bhavin cauhan

A Machine Which can make 1 ton of ice in 24 hour from
water....i.e It is the rate of heat removed from the water
to make it ice

Answer / ansar

1ton ac is take 1.2kw electrical load

Answer / s.dency

The tonnage is shortly called as Ton which is the unit of
measurement. It measures the amount of cooling capacity of a
system. One ton of cooling is based on the amount of heat
needed to melt one ton (2000 lbs.) of ice in a 24 hour
period. One ton of cooling is equal to 12,000 Btu/hr.

Answer / harshal v.p.o

1 tonne AC : it is the capacity of the compressor of Air
Conditioner,which can remove the heat generated in the
particular room,such that the amount of heat is equivalent
to melt a block of 1 tonne ice in 24 hours.

Latent heat of ice= 144 BTU
1 TR= 144 X 2000
= 288000 BTU/24

For 1 hour

If you dividing by 24
288000/24=12000BTU


Thank You

Answer / c.m.kashif abrar

The amount of hear absorbed by melting one ton of ice in 24 hours. Equal to 288000 Btu's per day 12000 Btu's per hour or 200 Btu's per minute.

Answer / harshal v.p.o

1 tonne AC : it is the capacity of the compressor unit,
which can remove the heat generated in the particular
room ,such that the amount of heat is equivalent to melt a
block of 1 tonne ice in 24 hours.

5 Answers   Emco,

We are preparing another project which involves Waste heat recovery from a 1 MW GE Engine. The Engine in particular gives out flue gas at 487Deg C with a flow rate of 5650 kg/hour and this can be cooled to 180 Deg C. This gives a thermal output of ~ 594 KW that is available for input to VAM via heat exchanger / boiler. Additionally 581 KW will be available from engine jacket water (temperature profile 80/ 80 Deg C and a flow rate of 50m3/hr) Our estimation is that 300 TR of cooling is possible with a suitable VAM machine(s). Please advise what is the most suitable arrangement with maximum TR and min Capital expenditure. plz reply me as early as possible
