Evaporative Cooling Originated in an ancient idea

Description

Around 2000 years ago, ancient Egyptians pour water on the reed and put it up as a curtain to cool the room.

In the early 1900s, wood wool was used together with fans and water to form the earliest evaporative air cooling units.

In the 1950s, an evaporative cooling pad was invented, which is widely used all over the world as the most natural cooling way.

Evaporative Air Cooler, as the modern industrialized product based on this ancient theory, brings this benefit to every aspect of our life.

The pump circulates water from the water tank onto a cooling pad, which in turn becomes very wet. A fan draws hot air from outside the unit through the moistened pad. As it passes through the pad the air is cooled by evaporation, and then is pressured out by a ventilator.

Evaporative air cooler can be installed on the roof, wall, or ground, wherever suitable.

When cooled air is blowing into the building constantly by the evaporative air cooler, the hot air inside the building is forced out, and the pressure difference between inside and outside the building will lead to continuous air exchange, so a certain quantity of doors and windows shall be kept open to facilitate the air exchange during air cooler’s operation.

Heat stress puts a huge influence on the growth and development in both agricultural and cultivating applications, as plants and animals are very sensitive to the changes in temperature and humidity.

The evaporative cooling pad system, as one of the most efficient and economical cooling way for agricultural and breeding applications, provides ideal temperature and a comfortable environment during the hot summer.

The ventilation fan and cooling pad frame shall be installed on a different wall side to ensure fluent airflow.

The air is exhaust out during the ventilation fan’s operation, which creates a negative pressure inside the building, then air from the cooling pad frame side will flow into the building to keep the pressure balance, and the air temperature drops when it goes through the cooling pad which saturated with water, due to the evaporation occurs during this process.
