The Thermal Diffusivity of Biochar Coating Deposited on a Heat Exchanger

“…In this cycle, the air flow to be saturated consists of a part of the air flow that has been cooled, which is reintroduced into the heat exchanger. As a result, the limit temperature, to which the remainder of the cooled air flow can theoretically be brought, is not the wet bulb temperature, but the dew point temperature [1]. Despite reaching coefficients of performance 5-6 times higher than traditional cooling systems [2], evaporative coolers are often penalized by continuous water pump operation, due to the constant spray of water in the wet duct, to homogenize the humidification of the heat transfer surface [3].…”
