This handy Air Conditioner Size Calculator will help you determine the appropriate size and capacity of an air conditioner for a particular area or room.
The AC Capacity calculator provides an estimate of the optimal air conditioner size based on factors like the dimensions of the room, the number of people in the room, the highest temperature etc.
As a result, a comfortable environment is maintained through efficient and effective cooling.
User Guide:
- Enter Room Dimensions: Enter the dimensions of the room or space in the designated input fields. Please provide the dimensions in foot-inch format (e.g., 10-6 for 10 feet 6 inches).
- Room Height: Enter the height of the room or space on foot. Taller rooms have a higher cooling load.
- Number of People: Specify the number of people who will typically occupy the room.
- Highest Temperature in Summer: Input the highest temperature recorded during the summer season in Celsius. This factor is crucial in determining the cooling load. The calculator considers different temperature ranges to provide an accurate estimation.
- Click Calculate: After filling in all the necessary information, click the "Calculate" button. The calculator will process the inputs and provide the recommended air conditioner size in tons.
- Interpret the Result: The calculated air conditioner size will be displayed in a red-colored box below the calculator. The result is presented in tons, representing the capacity required for efficient cooling.
Remember, the calculated size is an estimate based on the inputs provided. It is recommended to consult with an HVAC professional or refer to the manufacturer's guidelines for precise sizing and selection of an air conditioner for your specific needs.
Note: The calculator assumes certain default values and formulas to estimate the air conditioner size accurately. These faults can be modified as per specific requirements or updated industry standards.
Base air conditioner capacity
Refer to the following chart to determine base air conditioner capacity for your room. The table shows area of your room in Square Feet and in Square Meter with the corresponding AC capacity:
| Sr. | Area of Room in Square Feet | Area of Room in Square Meter | Ac capacity in ton |
|---|---|---|---|
| 1 | 100 - 200 | 30 - 60 | 1 |
| 2 | 200 - 400 | 60 - 120 | 1.5 |
| 3 | 400 - 500 | 120 - 150 | 2 |
| 4 | 500 - 700 | 150 - 210 | 2.5 |
| 5 | 700 - 900 | 210 - 275 | 3 |
How to Calculate Air Conditioner Size?
The Air Conditioner Size calculation is a process to determine the appropriate capacity or size of an air conditioner required for a specific room or space. The size of an air conditioner is typically measured in tons (1 ton equals 12,000 BTU per hour).
The formula used to calculate the Air Conditioner Size is as follows:
Air Conditioner Tons = ((Length × Width × 20) / 12,000) + No of Person + Temperature + Height
Here's what each component of the formula represents:
1) Length and Width: The length and width of the room or space in feet. These dimensions are used to calculate the area of the room.
2) No of Person: The number of people present in the room. The formula accounts for the additional cooling load caused by the presence of people. For up to 3 people, the value is 0.3. For each extra person, an additional value of 0.07 is added.
3) Temperature: The highest temperature in Celsius during the summer season. The formula considers the impact of temperature on the cooling load.
The value is determined based on specific temperature ranges:
- If the highest temperature exceeds 45 °C, the value is 0.5.
- If the highest temperature is between 41 and 45 °C, the value is 0.4.
- If the highest temperature is between 36 and 40 °C, the value is 0.3.
- If the highest temperature is less than 35 °C, the value is 0.2.
4) Height: The height of the room or space in feet. The formula takes into account the additional cooling load due to the height of the room. For each foot over 8 feet tall, an additional value of 0.1 is added.
By plugging in the appropriate values into the formula, the calculation provides an estimate of the required Air Conditioner Size in tons for effective cooling in the given space.
