# Evaporative Cooling Size Calculator

## Evaporative Cooling Size Calculator

An Evaporative Cooling Size Calculator is a tool used to determine the appropriate size of an evaporative cooler needed to cool a particular space. Evaporative cooling works by drawing in hot, dry air and passing it through a wet pad or media, which cools the air through the evaporation of water. The cooled air is then blown into the room, providing a comfortable and refreshing atmosphere.

The size of the evaporative cooler needed depends on several factors, such as the size of the space to be cooled, the humidity levels in the area, and the desired level of cooling. A size calculator takes into account these factors and provides an estimate of the appropriate size of the evaporative cooler needed for the space.

Using an evaporative cooling size calculator can help ensure that the evaporative cooler is not too small or too large for the space, which can impact its efficiency and effectiveness in cooling the area.

## Formula Evaporative Cooling Size Calculator

The formula for evaporative cooling size calculator is based on the calculation of the cooling capacity required for a particular area. This is determined by the heat load, which is the amount of heat that needs to be removed from the space to maintain a comfortable temperature. The formula is as follows:

Evaporative Cooling Capacity (in CFM) = (Area x Height x Air Change Rate) / 2

Where:

• CFM stands for Cubic Feet per Minute, which is a unit of measurement for air flow
• Area is the area of the space in square feet that requires cooling
• Height is the height of the space in feet
• Air Change Rate is the number of times the air in the space is replaced with fresh air in one hour. The recommended air change rate is 20 to 30 times per hour for evaporative cooling.

Suppose you have a room that measures 20 feet by 20 feet with a ceiling height of 10 feet. The recommended air change rate is 20 times per hour. What is the required evaporative cooling capacity in CFM?

Evaporative Cooling Capacity (in CFM) = (Area x Height x Air Change Rate) / 2

Area = 20 ft x 20 ft = 400 sq ft Height = 10 ft Air Change Rate = 20 times per hour

Evaporative Cooling Capacity (in CFM) = (400 sq ft x 10 ft x 20 times per hour) / 2 = 40,000 CFM

Therefore, the required evaporative cooling capacity for the given room is 40,000 CFM.

This means you should choose an evaporative cooler with a capacity of at least 40,000 CFM to effectively cool the space.

Once you have calculated the required evaporative cooling capacity in CFM, you can use this information to choose an appropriate evaporative cooler for your space. It is important to choose a cooler with the appropriate capacity to ensure that it is effective at cooling the space and to avoid overworking the unit.

Note: This formula is an approximation and should be used as a guide only. Other factors such as humidity, ventilation, and insulation should also be taken into account when determining the appropriate size of an evaporative cooler. It is recommended to consult a professional HVAC technician for a more accurate calculation.

## FAQs about Evaporative Cooling Size Calculator

Some of the most asked questions related to Evaporative Cooling Size Calculator are as follows…

### What is an evaporative cooler?

An evaporative cooler is a cooling device that uses the natural process of evaporation to cool air. It works by drawing warm air into the cooler and passing it through a wetted pad or media, which cools the air through the process of evaporation.

### How does the evaporative cooling size calculator work?

The evaporative cooling size calculator works by calculating the cooling capacity required for a particular space based on its area, height, and recommended air change rate. It uses this information to determine the required evaporative cooling capacity in CFM.

### What factors should be considered when choosing an evaporative cooler?

When choosing an evaporative cooler, factors such as the size of the space, the humidity level, the ventilation, and the insulation should be taken into account. It is recommended to consult a professional HVAC technician for advice on the appropriate cooler size and type for your space.

### What are the benefits of using an evaporative cooler?

The benefits of using an evaporative cooler include lower energy consumption compared to traditional air conditioning systems, lower initial and maintenance costs, and improved air quality due to the continuous introduction of fresh air into the space.

### Can an evaporative cooler be used in any climate?

Evaporative coolers are most effective in dry climates where the air is not already saturated with moisture. In humid climates, they may not be as effective at cooling the air due to the already high humidity levels. It is important to consider the climate when choosing an evaporative cooler.
