How do you calculate ton of refrigeration?
A kilo-calorie is the amount of heat required to raise or lower 1 kg of water by 1°C. One ton of refrigeration is equal to 3024 kilo-calories per hour. This is 12,000 BTU/ h divided by 2.204 (pounds per kilogram) divided by 1.8 (°C to °F).
What is 1 ton of refrigeration explain?
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. 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 are chiller tons calculated?
Divide Q (BTUs per hour) by 12,000 (the number of BTUs in one ton of cooling capacity). This yields the chiller capacity required to handle the process heat load in tons per hour: Example: 240,000/12,000= 20 tons/hr.
Why is refrigeration measured in tons?
The use of tons to measure cooling capacity comes from this time. A ton refers to the amount of heat it takes to completely melt a ton of ice. Melting this amount of ice requires 286,000 Btu (British thermal units). Rounding up 11,917 Btu/hr gives you 12,000 Btu/hr, which is one ton of air conditioner capacity.
What is HVAC ton?
A ton is a unit of measurement for determining cooling capacity. One ton (or tonne) equals 12,000 Btuh. “Tonne” is typically used for cooling products manufactured outside the U.S. Lennox® air conditioners and heat pumps are available in tonnages ranging from 1.5 to 5 ton capacities.
How do you calculate tons of cooling capacity?
To estimate your AC tonnage needs, multiply the number of square feet you’re cooling times 25. This equals the total number of BTUs you need to adequately cool your space. Next, divide that number by 12,000 to determine the tonnage capability you need in your new air conditioning unit.
What is chiller tonnage?
A water chiller refrigeration ton is defined as: 1 Refrigeration Ton (RT) = 1 Ton – 12000 BTUH/h = 200 Btu/min = 3025.9k Calories/h = 12661 kJ/h = 3.517 kW. 1kW = 0.2843 Refrigeration Tons (RT) 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.
How do you calculate TR?
How to calculate total revenue
- total revenue = (average price per units sold) x (number of units sold)
- total revenue = (average price per services sold) x (number of services sold)
- total revenue = (total number of goods sold) x (average price per good sold)
- total revenue = (40,000) x ($5)
- total revenue = $200,000.
How many kW is in a ton?
Kilowatt to Ton (refrigeration) Conversion Table
| Kilowatt [kW] | Ton (refrigeration) |
|---|---|
| 1 kW | 0.2843451361 ton (refrigeration) |
| 2 kW | 0.5686902722 ton (refrigeration) |
| 3 kW | 0.8530354083 ton (refrigeration) |
| 5 kW | 1.4217256805 ton (refrigeration) |
What is ton capacity in AC?
So, if you room is 100 sq. feet, the basic AC capacity required will be 0.167 tons (100 / 600). Now, you need to add 0.5 ton to the basic capacity for every five people in the room. Ordinarily, an AC of 0.8-ton capacity will work just fine for a 100 sq. ft room.
How many BTU per ton of cooling?
One Ton of Cooling is equal to 12,000 BTU/h. A condenser unit that can continuously cool at 12,000 BTU per hour has a 1 ton capacity. According to Dr-Fix-It, the name comes from the fact that it takes 288,000 BTU to melt one ton of ice at 32 °F to water at 32 °F in 24 hours, which is 12,000 BTU per hour.
How many BTU per ton of HVAC?
Converting Btu to tons is fairly simple. One ton is equivalent to 12,000 Btu. A rule of thumb if you haven’t mathematical computed your HVAC needs is to use 1 ton for 500 square feet.
How do you convert BTU to tons?
How to convert BTU/hr to tons. One refrigeration ton is equal to 12000 BTUs per hour: 1 RT = 12000 BTU/hr. One BTU per hour is equal to 8.33333×10-5 refrigeration ton: 1 BTU/hr = 8.33333×10-5 RT. So the power P in refrigeration tons (RT) is equal to the power P in BTUs per hour (BTU/hr) divided by 12000:
