Evaporative Cooling At Commercial Buildings.


Evaporative cooling is a modern technology that uses evaporation and blowing air to cool buildings. It might be a single cooling source, or it might be incorporated with an air conditioning system.

In general, there are three types of evaporative cooling systems found in commercial buildings:

  1. Direct evaporative cooling.

  2. Indirect evaporative cooling.

  3. Direct/indirect evaporative cooling.

Direct Evaporative Cooling

Direct evaporative cooling is the most typically used innovation in household applications. This type of system is widely described as an overload cooler. Direct evaporative cooling cools down the air by vaporizing water and raising the dampness material of the air. A blower guides air throughout a media part, such as a wetted pad, which is consistently filled with water to promote heat transfer from the cozy water to the colder air. Excess water is accumulated at the end of the cooling media, and a pump recirculates it from the storage tank. A float valve manages the water level. Then, a fan presses the fresh, amazing, humidified air out of the system. Direct evaporative cooling is finest matched for warm and completely dry climates.

Indirect Evaporative Cooling

Indirect evaporative cooling makes use of an air-to-air heat exchanger to eliminate heat from the air. Unlike direct evaporative cooling, the main air in an indirect evaporative system cannot be found in direct contact with the wet air in the heat exchanger. The primary blower fan produces outside air that is cooled down by traveling through the heat exchanger as it is attracted to the structure. A secondary fan attracts exhaust air from the building and/or outside air with damp pads, giving trendy air, which takes heat from the inbound supply air as the two air stream across courses in the heat exchanger. Thus, the damp air is worn down while cooled dry air is blown right into the room.

Direct/Indirect Evaporative Cooling

An indirect cooling system might be incorporated with a 2nd direct evaporative cooling stage prior to the conditioned air going into the building to even reduce the temperature level of inbound air. This two-stage system is commonly described as an indirect/direct evaporative cooling or (IDEC) system.
