Design procedure of desiccant and evaporative cooler based 100% outdoor air system
Min-hwi Kim, Joon-young Park, Eun-ji Lee, Jae-weon JeongAbstract: When designing a desiccant and evaporative cooler based 100% outdoor air system, energy and thermal performance are significantly affected by three major components. These are the indirect evaporative cooler, direct evaporative cooler, and liquid desiccant system. In this proposed system, two types of systems can be obtained by applying a sensible heat exchanger in the OA intake. Because of these design elements of the proposed system, the design process is not easy to understand. This paper thus presents a design process and a tool for the design of a liquid desiccant and evaporative cooler based 100% outdoor air system. Specifically, this paper shows a method for estimating the capacity of a liquid desiccant system depending on the system configurations. Seven design steps are required to determine the liquid desiccant system, and indirect and direct evaporative cooler capacities. How the design affects the indoor thermal environment is also evaluated. The proposed design procedure could provide a system solution to the HVAC system consultant and designer.
