Abstract
This study aims to supply sufficient drinking water for hot land regions in Ethiopia, specifically higher institutions such as ASTU, Dilla, Semera, Derie dawa, Gambiela and Assosa Universities. The investigation focuses on evaluating the performance of locally manufactured public water coolers developed using the VCRS system.
The predestined parameters are inlet temperature of water (44 ℃), the estimated time, the volume of water, surrounding temperature of the air (28 ℃), and heating load of evaporates (12847.87 kJ). Two models are designed in the present investigation, the first one for experimental and the second for numerical analysis and for compare with experimental analysis and previse investigation. After design and select the component the model developed and simulated using EXCEL. R134a is selected as a refrigerant because it has less global warming potential, zero ozone depletion potential value, inexpensive and easily available. Aluminum sheet, R134a, spray foam, thermostat, and VCRs components are materials used to fabricate the coolers. The walls of the storage tank is wounded by the evaporator coil. Due to high performance of cooler, the storage type of water cooler is selected. The theoretical results have been validated with experimental results and the present study compares with the literature. As per this investigation, the cop of the cooler is recorded 3.17 and 3.89 for experimental and theoretical results respectively. This result variation is detected due to ideal assumption of VCRs process.
