成果简介	NOVELTY - Water-based indirect direct evaporative cooler with air mixing comprises: a secondary airflow module for facilitating the secondary air to directly interact with water, resulting in evaporative cooling and lowering the temperature of the secondary air and water from the water-cooling unit; a mix air flow module, where cold secondary air is first mixed with primary air, which become cools down due to mixing; an air-to-water heat exchanger configured to interact indirectly with the mixed airflow so it cools down without increasing its humidity; a primary mixed airflow module for facilitating the mixed air directly to interact with water again and further cooling down due to the natural evaporative adiabatic cooling; and a fan configured for forced delivery for the cooled mixed air. USE - The water-based indirect direct evaporative cooler with air mixing is useful for industrial and residential use. ADVANTAGE - The cooler has improved cooling performance without using refrigeration or thermos-electromechanical system technology; and provides less humidity and low construction and running costs. The water for indirect heat exchanger cooling reduces inlet dry and wet bulb air temperature without increasing the humidity. The secondary and primary air are mixed to fully utilize the airflow, resulting in the decreased air temperature. The outlet temperature of the air is less with the same amount of humidity than a traditional cooler. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is also included for method for delivering cool air using the water-based indirect direct evaporative cooler with air mixing, involving providing the secondary airflow module for facilitating the secondary air to directly interact with water, resulting in evaporative cooling and lowering the temperature of the secondary air, providing the air-to-water heat exchanger configured to interact indirectly with the primary airflow with the cooled secondary air, thus cooling the primary air without increasing its humidity, and providing the primary airflow module for facilitating the mixed air directly to interact with water again and further cooling down due to the natural evaporative adiabatic cooling and delivering cooled mixed air through the fan. DESCRIPTION OF DRAWING(S) - The drawing shows a schematic representation of the water cooling unit working principle of water-based indirect direct evaporative cooling with air mixing.
