Objective of reducing primary energy consumption and the integration of renewableĮnergies in buildings, instead of using fossil fuels. Suggested that highly compact indirect evaporative coolers can achieveĪir-cooling processes with a low energy consumption and a low environmental impact. The experimental results showed that theĬooling capacity per unit volume of the device was 177 kW/m³, and theĬooling capacity per unit airflow rate was 10.9 kW/(m³/s). The cooling unit performance indicators were the cooling capacity per An experimental facility was designed to study these air-cooling Finally, the IEC system was studiedĮxperimentally. Water distributing system and an outer casing. The device consisted of a compact heat and mass exchanger, a Humidity distributions of the air inside the exchanger. The mathematical model allowed to obtain the temperature, enthalpy and Firstly, a mathematical model based on ε-NTU numerical method toĭetermine the optimal geometrical and operating parameters of an IEC system wasĭeveloped. Present work was to design and manufacture a highly compact indirect evaporativeĬooler. Separated by a heat transfer surface with a dry side, where only air is cooled,Īnd a wet side, where water is evaporated into air. DEC is based on direct contact between airĪnd water, while IEC is based on heat and mass transfer between two flows of air, There are two main types of evaporativeĬooling systems: the direct evaporative cooling (DEC) system, and the indirectĮvaporative cooling (IEC) system.
