What is the Procedure of Heat Load Calculation

Plz define the Right Formula

Thanks.

Here are a few ways to calculate your BTU's.

Get ready to use that algebra you thought you'd never use.

1 Ton = 12000 BTU's

400cubic feet per minute (CFM) = 1 Ton on standard ac units (300 is an absolute minnimum)

BTU's air heat = difference in temp. ( ∆T ) x 1.08 x CFM

∆T = BTU's / (1.08 x CFM)

i.e. 65◦F entering your unit and 93◦F air leaving on a 12000BTU unit.

∆T = 28

CFM = 400

28 x 1.08 x 400 = 12096BTU's

Another way...

Electric heat calculations.

BTU's = KW (killowatts) x 3413

Watts = Volts x Amps (single Phase) Most Homes))

Watts = Volts x Amps x Phase (this is for three phase units.)three wires and a ground))

120 volts 30 amps single phase (common)

120 x 30.0 x 1 = 3600 or 3.6KW 3.6 x 3413 = 12286BTU's

You can't.

There is no formula to convert Cubic Centimeters to Horsepower. It doesn't work that way.

Apples and Oranges.

CC's are a unit of volume and horsepower is a calculation of work load. Only a dyno would be able to tell how much horsepower a given displacement will/would make.

You could have 2 identical CC engines and have totally different HP outputs.

You can't. There is no formula to convert Cubic Centimeters to Horsepower. It doesn't work that way. It is like comparing Apples and Oranges.

CC's are a unit of volume and horsepower is a calculation of work load. You could have 2 identical CC engines and have totally different HP outputs.

Now if your had the engine's torque values like 6.5 FT LB @ 3050 rpm then you can convent that.

Each specific solid (shape) that has some regularity has a formula which can be used to calculate its volume. If it has no regularity the calculation will be more complicated.

For a right rectangular prism with dimensions L, W, H the volume is L*W*H. For a right circular cylinder with radius r and height H, the volume is Pi*r^2*H.

Once you know the formula, it is an easy matter to use the calculator to evaluate the volume.

The Old Rule of Thumb is 400 square feet per ton, but you really need to do a heat load calculation to be safe. A lot of windows on the west or south side of the house will really increase your load and you may need a lot larger unit. Insulation also changes your load so you may be able to cool a larger area. You may be able to get the Heat Load Calculation Form either online or from Johnstone supply. They are on the internet.

Dont get a heatpump unless you have a lot of time and money to devote to a constant pain in the ***. Keep it simple electric heat or gas heat you will thank me later.

It's not fixed formula, but as per basic rule, easy method tocalculate for motor capacitor.
(2650 X full load amps) divided by supply voltage(mentionedin capacitor)= MFD. (Plus or minus 10% to 15%)
Ex: 1 Tr which gives full load amps of 6 amps (2650 X 6)=15900 divided by 240(VAC)volts=66.25MFD
(10% to 15% plus or minus) You can fix 56.32 mfd or 76.18mfd
So, you can go in between 56.32 mfd and 76.18 mfd.
If you calculate of 440VAC capacitor, it will be 36 mfd.
Hope, it will be helpful . Thanks.

Constant 1.08 is a percentage of outside air being brought into a building or space you want to cool.

Most public or commercial building hvac use a outside air damper to allow fresh air to come in,allowing this air in will cause a constant load or heat.say its 92.f outside this 92.air will constantly be coming in and will need to be cooled.

Hope ive helped.

The DEG indicator on the screen is a reminder to the user that the ANGLE unit is in degrees. You can change the angle unit to Radian or Grads. That does not have any incidence on other calculations. It only affects the computation of trigonometric functions : sine, cosine, tangent, arc cosine, arc sine and arctangent. So if you have syntax error in the calculation of the interest formula, I can assure you it has NOTHING to do with the angle unit.

I do not see the formula you are trying to use, so I cannot be sure what you are doing wrong.

- Possible wrong usage of the regular minus sign instead of the change sign (-) or (+/-)
- Missing right parenthesis
- A right parenthesis is inserted at the wrong place.
- Incorrect use of the power function

There's a thumb rule in A/C air distribution. At 1 TR load, the air supply is about 400 CFM and the ideal diffuser size is 16" x 16" with an effective flow area of about 70%. Branch duct size for this outlet should be around 12" x 12".
