An Experimental Study on Bioclimatic Design of Vertical Greenery Systems in the Tropical Climate

Abstract The main problem related to thermal condition in Surabaya as a second-largest city in Indonesia is humid and hot. It is a typical condition of tropical climate. Ventilation in the hot day will bring warm and humid outdoor air into a room. It will increase the temperature of air in the room. One of some efforts to reduce the outdoor air temperature is using an earth to air heat exchanger (EAHE) to transfer heat from the air to the earth or ground. This paper will discuss about research done to study the effect of EAHE to a room temperature. The study used two model rooms which are similar and a model EAHE. One room called condition room will receive air flowing from the EAHE pipe and the other room is called the referent room. From the research, it is found that the air in condition room with EAHE is cooler in the daytime compared to the referent room. The temperature of the condition room with EAHE is more stable.

Calculation Results

This paper presents an experimental study of radiant cooling for building air-conditioning in a tropical climate. To prevent condensation of moisture on the cooling panel, the temperature of chilled water supplied to the panel was limited to 25°C. This led to the limitations of heat extraction capacity at the panel and its application to only space with low thermal load and low metabolic rate activity of people in the space. A simple calculation of radiative and convective heat exchange between the interior room surfaces and the room air was applied to determine the rate of heat extraction by the panels. The calculation results can match well with the measurement results. Using a comfort index of predicted mean vote (PMV), the results from experiments show that thermal comfort could be achieved with the application of radiant cooling.
