Evaporative cooling strategy using cooling pad material made from stove wicks in walk-up flat in the humid tropical climate of Surabaya

Abstract

Generally, the thermal conditions in simple flats for rent are still not within a comfortable range. There is no implementation of artificial ventilation (Air Conditioner) with adjustable air temperature, so passive strategies still need to be pursued. In this case, the strategy pursued is Direct Evaporative Cooling (DEC) system with cooling pads made from stove wicks. Experimental methods were conducted in one of the apartment buildings in Surabaya, namely Indrapura Walk-up Flat. The research results indicate that at relatively high outdoor air temperatures from 12:00 to 15:00 local time, ranging from 27.9 to 32oC, the implementation of DEC was able to reduce the air temperature by 1.94-2.08oC
