Both offer a measurement of an air conditioner’s cooling ability over an hour’s time. One ton of cooling capacity is equal to 12,000 BTUh. Residential air conditioners usually range from 1.5 to 5 tons (or, 18,000 – 60,000 BTUh). Anything with larger cooling capacity would be considered light commercial.
Mar 28, 2019· 1 Ton = 12,000 BTUs per hour, or the amount of energy it takes to melt 1 ton of ice in a day. Consequently, AC sizing involves determining the home’s cooling load: the exact capacity in BTUs per hour and cubic feet per minute of airflow required to maintain a 78 degree temperature in the house.
Capacity is defined as the weight or volume per hour of a bulk material that can be safely and feasibly conveyed using a screw conveyor. Screw conveyor diameter is determined by multiple factors including capacity. The following steps are required for proper screw conveyor selection: Calculate required capacity in cubic feet per hour (ft 3 /hr).
2. Determine how many pounds per hour are required for each ton of cooling capacity using Chart 1. Example: Polypropylene requires 1 ton of cooling capacity for every 35 lbs./hr processed; 75 lbs. ÷ 35 lbs. = 2.14 tons of cooling; 3. Determine if the extruder or any auxiliary equipment will require chilled water using Chart 2. If not, go to
Air Conditioning Term …. “Ton” 1 ton of capacity equals 12,000 Btu/hr … for 24 hours Background on the derivation for tons of refrigeration… and information on the similar SI standard The latent heat of fusion for ice is 144 BTU/lb. For one ton, that is 2000 lb x 144 BTU/lb, or 288,000 BTU. Refrigeration's roots are in the ice making industry,
Mar 25, 2019· For each material type, divide the total pounds processed per hour by the number of pounds per hour that can be processed with one ton of cooling, per the chart. For example, to injection mold PET at a rate of 300 pounds per hour, the material calculation is 300 / 45 = 6.67 tons of chilling capacity per hour.

Calculate BTU/hr. BTU/hr. = Gallons per hr x 8.33 x ?T°F; Calculate tons of cooling capacity; Oversize the chiller by 20% Ideal Size in Tons = Tons x 1.2; You have the ideal size for your needs; For example, what size chiller is required to cool 40GPM from 70°F to 58°F??T°F = 70°F - 58°F = 12°F; BTU/hr. = 40gpm x 60 x 8.33 x 12°F
Jun 29, 2011· We will use that number to select a heat pump that can handle the load. 12,000 BTUs per hour is one ton of capacity, so we will need a 3-ton unit. Keep in mind that the nominal rating for heat pumps from different manufacturers will differ and not all 3-ton heat pumps will produce exactly 36,000 BTUs per hour. However, this is a solid estimate.
Air conditioners are sized by cooling capacity in BTU's per hour. To estimate the optimum capacity for any room, first calculate the size of the area to be conditioned by multiplying its width times its length, measured in feet. • 80 to 200 tons (280 to 700kW) – Reciprocating, Screw or Centrifugal • 200 to 800 tons (700 to 2800kW
Then divide this by 1000 to get the ton capacity. Example if the room’s size is 10 feet by 10 feet by 10 feet. So 10 X 10 X 10 comes out to 1000, divide this by 1000 the answer comes to 1. So your as tonnage requirement is one ton. Another example room size 12 feet …
May 11, 2017· The following table provides a guide for choosing the right size air conditioner based on the area needing to be cooled. The Air conditioner output and capacity is measured in BTU per hour. This chart includes areas from 100 square feet up to 2,500 square feet for comparison. Area To Be Cooled (square feet) Capacity…
