This study investigated the cooling and dehumidification performance of a PT A/C that is solely powered by solar energy under tropical climate conditions. The system is built with 9 pieces of thermoelectric to provide cooling for a test chamber of 3.6 m3 volume. The effect of input current on the system�s cooling and moisture removal rate were investigated and results showed that 5 A is the optimum current level, providing an average of 181 W cooling capacity and 0.14 ltr/hour of moisture removal rate at the given ambient conditions. During the operation, indoor temperature of the test chamber was 4 °C lower than the unconditioned chamber and 7.7 °C compared to the ambient temperature. Whereas the indoor relative humidity varies between 58~83 . Furthermore, for a 12 hours operation, the system consumes 1.45 kWh of energy, and delivered temperature between 23.8 to 27.8 ºC at 5 A. © 2020, The Korean Society of Mechanical Engineers and Springer-Verlag GmbH Germany, part of Springer Nature. date: 2020 publisher: Korean Society of Mechanical Engineers official_url: https://www.scopus.com/inward/record.uri?eid=2-s2.0-85084457099&doi=10.1007%2fs12206-020-0441-8&partnerID=40&md5=47908e130b95b0cd90c6134aa880641f id_number: 10.1007/s12206-020-0441-8 full_text_status: none publication: Journal of Mechanical Science and Technology volume: 34 number: 5 pagerange: 2199-2205 refereed: TRUE issn: 1738494X citation: Looi, K.K. and Baheta, A.T. and Habib, K.
