What is indirect cooling system?

condair.co.uk
Indirect evaporative cooling works on the same principle as direct evaporative cooling lowering air temperature by causing water to evaporate. The main difference with an indirect system is that a heat exchanger is used to cool the air supplied to the living space. The evaporative cooling cycle occurs in the heat exchanger.

How do evaporative coolers work?

  • An air cooler works by evaporating the water. It lowers the temperature of the air using evaporative cooling. It is the addition of vapour in the air to reduce the heat. The energy needed to evaporate the water is taken from the air in the form of sensible heat, which affects the temperature of the air.

What is evaporative cooling?

  • Blowdown,drift,and make-up water. In an evaporative cooling system,there are three sources of water loss: evaporation,blowdown,and drift.
  • Water distribution. One of the ways evaporative cooling systems accelerate the process of evaporation is by spreading out the hot water into a “spill area.”
  • Fill material. ...
  • Airflow. ...

What is direct cooling?

  • Direct evaporative cooling. Direct evaporative cooling (open circuit) is used to lower the temperature and increase the humidity of air by using latent heat of evaporation, changing liquid water to water vapor. In this process, the energy in the air does not change. Warm dry air is changed to cool moist air.

Indirect Cooling Systems. An Indirect system is designed so that there is no direct contact between the air and water that is being cooled and has 2 different fluid circuits.
