## What is TR capacity?

A ton of refrigeration (TR) is a unit of heat extraction capacity of the refrigeration or cooling equipment. 1 TR is approximately equal to 12000 BTU or 3024 Kcal/hr of energy/heat load. The heat of fusion of water is about 335 KJ/kg or 80.01 kCal/kg. 1 short ton is equal to 2000 lb or 907 kg.

## How do you calculate TR for refrigeration?

Some commercial and industrial refrigeration systems are rated in Tons of Refrigeration (TR, tons). A ton is the amount of heat removed by an air conditioning system that would melt 1 ton (2000 lbs.) of ice in 24 hours….Converting between Btu/h and Tons of Refrigeration.

Btu/h Refrigeration Ton kW
60000 5 17.6

What does 1tonne tr in refrigeration mean?

Explanation: 1 Tonne Rating (TR) means that the capacity is such that it can convert 1 tonne of water to ice i.e. 0C in 24 hours.

### What does TR stand for in HVAC?

From Wikipedia, the free encyclopedia. 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.

### How do you find Ahu TR?

1. Step 1: Calculate Square Footage. Determine the square footage of the area to be cooled.
2. Step 2: Multiply to Get BTU Value. Multiply the square footage by 25 to obtain the base BTU value.
3. Step 3: Divide by 12,000. Determine the estimated tonnage by dividing the total BTUs by 12,000.

How do you calculate CFM to TR?

@Abdul Riyaz • 21 Nov, 2016 • 1 like 1 TR = 400 cfm is a thumb rule used in this industry. However, it is not a constant and varies with different manufacturers. CFM is cubic feet per minute. TR is tonnage of refrigeration.

## How do you calculate TR and AR?

Average Revenue

1. AR – Average Revenue.
2. TR – Total Revenue.
3. Q – Total units sold.

## How is TR of VAM calculated?

So, simply TR required = Total Heat Load / 3024.

What does TR mean in refrigeration?

Ton of Refrigeration
Ton of Refrigeration (TR): Ton of Refrigeration (abbreviated as TR) is an important historical unit of refrigeration capacity. Originally 1 TR was defined as the rate of heat transfer required to make 1 short ton (2000 lbs) of ice per day from water at 0oC.

### What is the 1 ton of refrigeration?

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.

### What do you mean by TR of refrigeration?

A ton of refrigeration (TR), also called a refrigeration ton (RT), is a unit of power 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 melting of 1 short ton (2,000 lb; 907 kg) of pure ice at 0 °C (32 °F) in 24 hours. [1] [2]

How big is a ton of refrigeration power?

A ton of refrigeration (TR), also called a refrigeration ton (RT), is a unit of power used in some countries to describe the heat-extraction capacity of refrigeration and air conditioning equipment. A refrigeration ton is approximately equivalent to 12,000 BTU/h or 3.5 kW.

## Which is the unit of energy used in refrigeration?

ton (refrigeration) Definition: A watt (Symbol: W) is the SI (International System of Units) derived unit of power. It is defined as 1 joule per second and is used to quantify the rate of energy transfer.

## How much ice can be transferred in 1 TR?

Originally 1 TR was defined as the rate of heat transfer required to make 1 short ton (2000 lbs) of ice per day from water at 0 o C. American Society of Heating, Refrigerating and Air-conditioning Engineers (ASHRAE) defines 1 TR as equivalent to a refrigeration capacity of 3516.85 W or 3023.95 kcal/h.
