1. Principled operation of evaporative cooling system

Evaporative cooling system making negative pressure operates under principle to make negative pressure in a workshop by the following way:

At a gable of the workshop, exhaust fan having large air flow is installed to exhaust  total hot and poluted air and industrial dust inside the workshop to eliminate outside.

At the opposite gable of the workshop, the system of frames of evaporative cooling pads (including evaporative cooling pads and water distribution pads with a standard size put together and surrounded by stainless steel gutters) is installed. These pads are supplied water regularly by water pump by the way watering regularly on the surface of water distribution pads then wetting all the surface of evaporative cooling pads. After flowing through evaporative cooling pads, water will falls into the gutters and through recovering PVC line to return the tank to join a new circulation. Because of the different pressure between inside and outside the workshop, hot and dry air will be exhausted through evaporative cooling pads exchanging temperature with water to become fresh and cool air  and suitable humidity. As a result, air temperature inside the workshop is decreased .

2. Markets of the system: In workshops producing textile and garment products, shoes, packing, mechanics,…and farms breeding cattle, poultry and growing flowers, pot plants,…
