How many liters of water does an air cooler need to run for 8 hours?

Most air coolers require between 15 to 20 litres of water to run continuously for eight hours. While this water capacity required for an air cooler is representative, the real number depends on the cooler’s capacity, ambient temperature, and humidity levels.

Small personal air coolers typically need between 1.5 and 2 litres of water per hour while larger units can consume up to 5 litres per hour.

How many liters are required for an air cooler for at least 8 hours?

It is important to understand your air cooler’s water consumption since it can help avoid mid-night refills. To understand the water needed for your air cooler, consider following:

1. Check your cooler’s tank capacity

2. Estimate hourly consumption: Tank capacity ÷ stated runtime

3. Multiply hourly rate by eight hours

It is worth noting that your air cooler’s water consumption can be affected by factors such as high temperature leading to evaporation, humidity levels, fan speed settings where high-speed operation can increase water usage, while larger spaces require more cooling capacity and thus more water.

During hot weather conditions, consider a 20 per cent buffer in water consumption. Try to run your cooler at medium speed, place it near a water source for easy refill, and use ice cubes to enhance cooling.

FAQs

Q1. How often should I refill my air cooler?

A: During continuous use, check your cooler’s water levels every 3-4 hours and check if your cooler has a minimum level indicator.

Q2: Does adding ice help reduce water consumption?

A: No, but adding ice helps improve cooling efficiency and reduce evaporation.

For 8-hours operation, you must ensure that your air cooler has 15 to 25 litres of water. For best result, consider your air cooler’s water tank capacity, monitor water usage regularly, and manage consumption based on weather conditions.
