Abstract

Dew point evaporative cooling (DPEC) technology has been used to produce low temperature air, whose temperature is even beneath its wet bulb temperature of intake air and close to its dew point temperature. This paper summarizes energy, economic, and environmental (3 E) assessments of the DPEC technology based on experimental testing, life cycle cost and CO2 emission models. Three vital aspects of the technology energy performance evaluation, including coefficient of performance, cooling capacity and cooling effectiveness, are investigated and compared between two prevalent categories (i.e., cross and counter flow configurations) in different climate conditions, and the hybridization of the DPEC system with dehumidifier and desalination applications is clarified. Various economic assessment approaches to study the net present value and payback period of the DPEC system are illustrated. The environmental impact evaluation of the DPEC system, including CO2, CH4 and N2O emissions, is conducted. At last, the viewpoints, suggestions and potential future development on the DPEC technology are deliberated.
