Evaluation of temperature and relative humidity on two types of zero energy cool chamber (ZECC) in South Sulawesi, Indonesia

Abstract

Zero Energy Cool Chamber (ZECC) is a cooling chamber for storing fruits and
\nvegetables from the viewpoints of low cost and energy savings. The aim of the present study is
\nto evaluate temperature and relative humidity (RH) on two types of zero energy cool chamber
\n(ZECC) in South Sulawesi, Indonesia. The first category was placed underground while the second category was on the surface. Then, the performance of the ZECC was measured by calculating temperature and relative humidity. The results show that the ZECC was constructed on the surface produce lower temperature and higher RH compare to ZECC which placed underground. In average, the temperature in the outside (28.00 C) is greater than in inside (26.2 0 C) of the ZECC. On the other hand, the relative humidity in the outside (72.9%) is less than in inside (87.2%) of the ZECC. It was concluded that the ZECC where was constructed on the surface is more suitable than ZECC on the surface for decreasing temperature and increasing relative humidity.
