how many cfm per ton?

Air quantities (cfm): Thumb-rule 400 cfm per ton of cooling is needed for normal comfort applications, 500 cfm per ton of cooling for heat pump and high sensible heat applications, and 350 cfm per ton of cooling for high latent heat applications.

Now if you want to reduce theoretical concepts down to rules of thumb, the standard volume flow rate per unit of power in the HVAC industry is 400 cfm per ton, and a ton is 12,000 BTU's per hour, so 400 cfm per 12,000 BTU's per hour of cooling capacity.

Larger the cooling area, higher the AC rating. Here, 1.5 ton will have 50% more cooling capacity than a 1 ton AC. 1.5 ton capacity means a lot of cooling. ... 12,000 BTU (1 ton ac) is equivalent to about 3.5 kWh.

A ton is the cooling capacity of an air conditioning system. One ton is equal to the amount of heat required (288,000 Btu) to melt one ton of ice in a 24-hour period. A one-ton air conditioner is rated at 12,000 Btu per hour (288,000/24). A two-ton unit would be rated at 24,000 Btu per hour.

Actual cubic feet per minute (ACFM) is a unit of volumetric flow. ... This is the actual gas delivery with reference to inlet conditions, whereas cubic foot per minute (CFM) is an unqualified term and should only be used in general and never accepted as a specific definition without explanation.

Heating BTUs = CFM x ∆t x 1.08 of air per CFM x . 24 (the specific heat of air) x 60 (minutes in an hour.)

Heating BTUs = CFM x ∆t x 1.08 of air per CFM x . 24 (the specific heat of air) x 60 (minutes in an hour.) This factor will vary at higher altitudes and temperatures.

Assuming the minimum cooling capacity of 400 square feet per ton for your HVAC unit, a 1600 square foot home will require 4.0 tons of air conditioning to cool. Your HVAC unit will need to remove about 4.0 x 12,000 BTUs, or 48,000 BTUs, per hour to keep your home cool.

The General Rule of Thumb When estimating the amount of refrigerant in a residential A/C unit, the general rule that is used is in the 2-4 pounds per ton of cooling. Say, for instance, recharging a 3-ton A/C with a 35-foot line set from empty level will need an approximately 6-12 pounds of refrigerants.

One ton is equal to the amount of heat required (288,000 Btu) to melt one ton of ice in a 24-hour period. A one-ton air conditioner is rated at 12,000 Btu per hour (288,000/24). A two-ton unit would be rated at 24,000 Btu per hour.

“The conditioned air quantity for air conditioning should be about 400 CFM per ton of cooling capacity.” Does this rule-of-thumb strike a familiar note?

A 4 ton air conditioner is one that can remove 48,000 BTUs of heat per hour from the house. For most people, though, 4 tons means 8000 pounds.

How many litres of oil will make one tonne oil? An older calculation would determine that since petroleum or motor oil weighs about 7.75 pounds per gallon, one tonne of that oil should be 2204 lbs divided by 7.75= over 284 gallons x 3.785= 1075 litres.

When calculating residential cooling capacity, it's common to assume an HVAC unit can cool 400 square feet per ton of air conditioning capacity. Given the Las Vegas climate, this number can reach a maximum of about 600 square feet per ton for most buildings.

The rule of thumb is two to four pounds of refrigerant per one ton of your unit. You should always check the specifications of your unit. However, most home air conditioning units are between one ton and five tons.
