Experimental Study on the Performance of an Air Conditioning Unit with a Baffled Indirect Evaporative Cooler

Energies
Indirect evaporative coolers (IECs) use the latent heat of water evaporation to cool air. This system has the advantage of operating at low power without a compressor and does not increase the absolute humidity of the air. However, an IEC is difficult to
