Direct Coolers - Direct Evaporative Cooling
Direct Evaporative Cooling systems utilize a water pump and a fan powered by a motor to expedite heat exchange. The water is distributed by the water pump to the cooling pads. In this process, air’s sensible heat and the perceptible heat are converted into latent heat. Latent heat is the heat that is not directly felt when water from the Evaporative Cooler evaporates into vapor. This transformation of sensible heat into latent heat results in the cooling of hot air. Consequently, the temperature of the air decreases. This cool air produced by the Breezair direct evaporative air conditioner is then distributed throughout the building and without being re-circulated is vented outside. Direct evaporative cooling is a simplest type of air conditioning that’s commonly used in dry areas
It’s important to note that Evaporative Air Coolers help to raise the humidity levels within the building. It provides fresh cool air while reducing the temperature. It’s the balance between temperature and humidity that determines human comfort. Direct evaporative air coolers are globally popular because they produce large amounts of cooling in vast areas and provide human comfort through the natural process of evaporation.
For example, a temperature of 40°C with a humidity level of 50% can be quite uncomfortable, but the same humidity level at a temperature of 30°C can be pleasantly comfortable. Direct evaporate cooling system maintains the balance between humidity and temperature. Moreover, comfort is further enhanced by the increase in air movement. Direct Evaporative Cooling generate enough airflow to mitigate the discomfort caused by high humidity.
