What is the principle of free cooling dry cooler?
The principle of free cooling dry cooler is based on using outdoor air to cool a liquid or a gas, typically water or a refrigerant, in a cooling system without the need for mechanical refrigeration. In this system, a dry cooler, also known as an air-cooled heat exchanger, is used to transfer heat from the liquid or gas to the outdoor air.
The basic principle of free cooling dry cooler operation is as follows: when the outdoor air temperature is lower than the temperature of the liquid or gas to be cooled, the outdoor air is circulated through the dry cooler, which is in thermal contact with the liquid or gas to be cooled. Heat is transferred from the liquid or gas to the outdoor air, which cools the liquid or gas. The cooled liquid or gas is then circulated back into the cooling system to cool the space or equipment.
By using outdoor air to cool the liquid or gas, the free cooling dry cooler reduces the need for mechanical refrigeration and associated energy consumption. This can result in significant energy savings, especially in climates where outdoor temperatures are lower than the desired cooling temperature. The system can also be equipped with controls and sensors to optimize the use of free cooling based on outdoor temperature and other factors, further improving its efficiency.
