A refrigeration ton is approximately equivalent to 12,000 BTU/h or 3.5 kW. Air-conditioning and refrigeration equipment capacity in the U.S. is often specified in "tons" (of refrigeration). Many manufacturers also specify capacity in BTU/h, especially when specifying the performance of smaller equipment
A ton of refrigeration (TR or TOR), also called a refrigeration ton (RT), is a unit of power used in some countries (especially in North America) to describe the heat-extraction capacity of refrigeration and air conditioning equipment. It is defined as the rate of heat transfer that results in the freezing (*or melting) of 1 short ton (2,000 lb; 907 kg) of pure ice at 0 °C (32 °F) in 24 hours.[1][2]
A refrigeration ton is approximately equivalent to 12,000 BTU/h or 3.5 kW. Air-conditioning and refrigeration equipment capacity in the U.S. is often specified in "tons" (of refrigeration). Many manufacturers also specify capacity in BTU/h, especially when specifying the performance of smaller equipment.
*It's important to note that the freezing or melting of the ice represents a change-of-state only, which is considered a transfer of latent heat, as opposed to a change in temperature which is a transfer of sensible heat.
The ton of refrigeration is equivalent to the consumption of one ton of ice per day and originated during the transition from stored natural ice to mechanical refrigeration. Just as horsepower and candlepower were intuitive units of measure for people living through the transition from horse to motorized transport and from flame-based to electric lighting, so was the ton of refrigeration an intuitive unit of measure during a technological change, as the ice trade gradually adopted over more artificial ice (ice from ice-making plant) in addition to its natural ice supplies. The TR unit was developed during the 1880s. Its definition was set at the level of an industry standard in 1903, when Thomas Shipley of the York Manufacturing Company led the formation of an industry association (the Ice Machine Builders Association of the United States) along with standardization of several equipment specifications.[3] In 1904 these efforts led to the founding of the American Society of Refrigerating Engineers (ASRE),[3] which was one of the predecessors of ASHRAE.

Sorry sir but L.H. of 1kg is 335 kj/kg and 1 ton is 335000 for 24 hours
But 1 mint = 335000/24×60 = 232.63
Yes that's what I was thinking
Comment nhi dekhta to mujhe ek or ghanta barbad krna prta😅
Thankyou bhai
Here 1 ton is US 1 ton which is equal to 907 kg
4:46 here Tonn refers to US Tonn system which is equal to 907 kgs..now rest of the calculation will make sense👍
Correct
Your understanding power is very good

It's so nice sir... Nice explanation... Funda clear for 1 ton refrigeration..nice work sir..
Thenk u.
1sec =3.86 kj/sec
1tr equal to not 210 kj/min
1tr equal to 232.63 kj/min
210 kese aatahe thoda batao sir. Please malum Nehi hore hai a
Calculation problem real answer showing in calculator (232.6/60)=3.8 KW. but we know 1 Tr -3.5 kw. So it's a big difference if anyone knows the reason tell me
Very nice
Good explanation
Thanks and welcome

Thank u very much sir itna achhe se samjha ne k liye. Sir bas ek calculation samajh me nhi aya 1 min. Ka jab nikale aap iss formula se 335000/24*60 to aap ka ans aya 210 kj/min but jab mai same formula se calculation kiya to mera ans aya 232.638888 kj/min.
Right answer hai Mera b itna Aya hai

Osm explaining this cocept
Sir methods of air refrigeration system padhye please
Sir . Temperraure of water Liquid to solid is 0 degree cels..then why would Ice start melts at 0 degree celsius??..0 degree is a freezing temperature na?
Bro....When Ice is kept in the room (i.e. in the atmosphere), then ice will definitely start melting as Ice will absorb the heat from the surrounding which means it's temperature gets changes...
Its temperature changes from from 0°C to till the surrounding temp with certain period of time and here we are assuming 24hours (1 day)
232.6388 a raha hai mera
Sir ky ap please energy conservation par video bana diye please
dear sir, your calculation of 1min is different from mine!!!... please help!
Sir, 1 tonn of ice absorbs heat in 1 min = 335000/24×60 = 232.66 aa rha hai par aapne 210 calculate kiya hai video mein plz explain..... 🙏
Yes we will get this
But for practical purpose we take it as 211

Per second
Sir eya pey to apka calculation mey 210 nehi hoga 232.63 hoga sir
