Comparative Analysis of Performance Between Window and Eco-Cooler to Achieve Thermal Comfort in Hot Humid Climate

Abstract

Abstract The increasing global temperatures have led to a higher demand for energy to maintain thermal comfort. In 2018, air conditioning was found to be the largest contributor to energy consumption, accounting for approximately 62% of the total energy used, according to data from the Ministry of Energy and Mineral Resources. Consequently, energy-saving initiatives that focus on cooling systems can play a crucial role in global energy conservation efforts. One such initiative is the implementation of Eco-Coolers. This study aims to compare the effectiveness of Eco-Coolers and windows in reducing room temperature for thermal comfort in hot and humid climates using Ansys simulations. The research adopts a quantitative approach by simulating the Eco-Cooler and window models using the Ansys application, followed by descriptive statistical analysis. The Eco-Cooler simulation involves a model with a diameter of D1 = 50 cm and D2 = 25 cm, which is then compared to a window measuring 45 cm × 100 cm. The results of the Eco-Cooler simulation demonstrate a decrease in temperature in all rooms where the Eco-Cooler is placed, with a maximum temperature of 27.05°C. This represents a decrease of 0.65°C from the initial temperature of 27.7°C. In contrast, the window model exhibits an upward airflow pattern, resulting in a maximum temperature of 27.35°C. This indicates a temperature drop of 0.35°C from the initial temperature of 27.7°C. Previous research on thermal comfort in Gorontalo City has shown that discomfort typically begins at a temperature of 29°C, with the peak of discomfort occurring at a temperature of 33°C. Therefore, based on the simulation results, the temperature range of 26.65°C – 27.05°C achieved by the Eco-Cooler can provide a comfortable or neutral sensation for individuals.
