The air conditioning and refrigeration equipment bases its operating principle on the recirculation of air through a heat exchange battery. During this process there is a transfer of latent heat that causes condensation of water inside the fins of the battery where micro-organisms are generated which are harmful both to the health of the workers and to some of the products they manufacture.
Additionally, the accumulation of bacteria and mold, among others, cause the partial clogging of the air flow surface, reducing the cooling capacity as well as the optimal ventilation flow rate, resulting in higher energy consumption.
