When we talk about air conditioner tonnage a one ton unit is equal to 12000 BTUs.

Air conditioner btu calculation formula. This is based on the most commonly used air conditioners these days which are split units with a CoP of 4. They are also by tonnage. BTU ratings specify how many BTUs the air conditioner moves.

Now we will multiply the length breadth and height altogether. A 12000 BTU AC captures 12000 BTUs of heat per hour and moves it. Lets suppose you have a server with a 500-watt heat dissipation output.

Length 12 feet. Most air conditioners are rated in BTU per hour British thermal unit. This is a simple calculator to help you decide what size of air conditioner you will need.

Area Calculation For Air Conditioner in BTU We must have an inch tape to measure BTU. It is approximately the energy needed to heat one pound of water by 1 degree Fahrenheit. It shows the quantity of thermal power essential to increase the temperature of 1 pound of clean liquid water by one degree Fahrenheit temperature at which water has.

So to calculate BTUhr use the following equation. BTU Number of sq. It measures how much heat your unit removes from indoor air per hour.

A British thermal unit BTU is a standard unit of power that is used in the United States and sometimes in the UK. Put the value in the equation. The way we measure temperature for the cooling BTU formula requires enthalpy as a factor in the formula.

Estimated Cooling Capacity needed C1 C2 BTUhr Air Conditioning Calculations - Other Factors. Each person produces about 500 BTUhr of heat for normal office-related activity. The simplest BTU calculation formula for an air conditioner looks like this.

BTUhr heat dissipation wattages x 34192. L-12 x W-14 x H-13 18480. 24 BTU specific heat of standard air BTULB F Where.

In India we usually measure in tonnage. C2 N x 500 BTUhr. 7000 Grains per lb68 60 1333 or 45 X 1060 7000 1060 See Enthalpy of air Total Heat Content of Air Table for exact values.

Add C1 and C2 together and you will get a very simplified cooling capacity needed for the room. Well when we talk about BTUs in relation to AC it refers to the amount of heat that the unit can remove from the air per hour. Q Q1 Q2 Q3 where Power of selected air conditioner Should be in the range from -5 to 15 Of the calculated power Q.

Simply fill in all the fields and we will generate a number of BTUs that you should use. Multiply this two figures together. Fi 60 Btu hr-ft2 -F 1Ri inside surface with still air Eq3 fo 163 Btu hr-ft2 -F 1Ro outside surface with moving air Eq4 Then for the whole concrete wall the thermal resistance to be used in the conduction equation 2 becomes.

We can measure the length breadth and height of our room with the help of inch tape. Width 14 feet. Height 11 feet.

Estimated calculation Cooling capacity Q KW Is carried out according to the generally accepted procedure. How to Calculate BTU. BTU is often used as a point of reference for comparing different fuels.

CoP stands for Coefficient of Performance - how efficient the air conditioner is and modern air conditioners can move 4 kilowatts of heat by using only 1 kilowatt of electricity. 1 watt is approximately 3412 BTU per hour. We have used our years of experience in air conditioning to put together this easy-to-use BTU calculator.

One ton is equal to 12000 BTU per hour. So a model with a higher BTU rating has more cooling power. Use this number as a guideline when choosing what size air conditioner would work best for your room whether its a window air conditioner or another type of small room AC unit.

The rating is actually BTUhour or the number of BTUs the air conditioner removes from the space in one hour. We find enthalpy by measuring wet bulb temperature and then converting it to enthalpy. To calculate cooling BTUs you will measure wet bulb temperatures to measure the changes in heat and moisture in the conditioned air.

20 However to get a perfectly-sized air conditioner with just right enough cooling power and no energy overspending you should consider some additional factors. Thats nice isnt itbut what does that have to do with air conditioners. 1060 Average Latent Heat of water vapor BTULB.
