Ton of Refrigeration (TR): Ton of Refrigeration (abbreviated as TR) is
an important historical unit of refrigeration capacity
. … American Society of Heating, Refrigerating and Airconditioning Engineers (ASHRAE) defines 1 TR as equivalent to a refrigeration capacity of 3516.85 W or 3023.95 kcal/h.
How do you calculate 1 ton of refrigeration?
| Btu/h Refrigeration Ton kW | 54000 4 1/2 15.8 | 60000 5 17.6 |

Why is it called a ton of refrigeration?
Before refrigeration air conditioning was invented, cooling was done by saving big blocks of ice. When cooling machines were invented, their capacity was rated by the equivalent amount of ice melted in a day, which is where the term “ton” came
from in sizing air conditioning systems
.
What is meant by 1 ton AC?
Air conditioning tonnage has nothing to do with weight. A ton, as used in the HVAC field, is a term that describes how much heat the AC unit can remove from a home in one hour. … One ton of air conditioning
can remove 12,000 BTUs of air per hour
. A four ton unit can move 48, 000 BTUs and so on.
What are the methods of refrigeration?
- Evaporative Cooling. Evaporative cooling units are also referred to as swamp coolers. …
- Mechanical-Compression Refrigeration Systems. Mechanical compression is used in commercial and industrial refrigeration, as well as air conditioning. …
- Absorption. …
- Thermoelectric.
What is the unit of refrigeration?
The unit of refrigeration is expressed in terms of
ton of refrigeration (TR)
. One ton of refrigeration is defined as the amount of refrigeration effect (heat transfer rate) produced during uniform melting of one ton (1000kg) of ice at 0°C to the water at the 0°C in 24 hours.
What is the weight of 1 ton AC?
| Indoor W x H x D 80 cm x 30 cm x 19 cm | Indoor Unit Weight 8.5 kg | Outdoor W x H x D 79 cm x 56 cm x 33.5 cm | Outdoor Unit Weight 28 kg |

How do you calculate 1TR?
internationally accepted standard for measuring the cooling effect of any refrigerator. Amount of cooling given by 1 ton of ice in 24 hours. 1TR=
900.7*335/(24*60)
= 209.5kj/min = 210kj/min(aprox.)
How many kW is a BTU?
| kW BTU/hr | How many BTU is 1 kW? 3,412 BTU | What is 2 kW in BTU? 6,824 BTU | What is 2.5 kW in BTU? 8,530 BTU | What is 3 kW in BTU? 10,236 BTU |

Which brand AC is best?
- Blue Star. …
- Voltas. …
- Lloyd. …
- LG. …
- Carrier. …
- Hitachi. …
- Mitsubishi. …
- Onida. Onida AC prides itself as an Indian brand and delivers innovative cooling technology suited to the Indian customer and their needs.
Should I buy 1 ton or 1.5 ton AC?
1 ton ACs can provide just the sufficient bit of cooling while not going too heavy with the electricity bill. While you compare 1 ton vs 1.5 ton AC, the rule of thumb is that
if you have a room which is more than 200 square metres, you should
be opting for an AC with a 1.5 ton capacity.
How many cooling watts are there in 1 ton AC?
A a rule of thumb, to calculate energy consumption consider 1 ton of AC is equal to
1000 watts
. (12000 x 1055) / 3600 = 3516 Joules / sec.
What is the basic principle of refrigeration?
The Refrigeration basic principle is that
with the aid of a heat pump, the refrigerant is being compressed to the condenser and capillary tube thus increasing its temperature (50-60°C) and pressure (750 kPa)
in the refrigerator being cooled down by the condensing unit to 32°C depending the existing ambient temperature.
What are the four stages of refrigeration?
The refrigeration cycle contains four major components:
the compressor, condenser, expansion device, and evaporator
.
Which gas is used for refrigeration?
| Synonyms CFC (chlorofluorocarbon), HCFC (hydrochlorofluorocarbon), HFC (hydrofluorocarbon) | Safe Work Australia ES TWA Refer to specific compound. |

How many BTU’s are in a ton?
The capacity of an air conditioner refers to the amount of heat it can remove. Rounding up 11,917 Btu/hr gives you
12,000 Btu/hr
, which is one ton of air conditioner capacity.
