Abstract

Ethylene glycol and water was used as a coolant in either cold or hot condition. The effectiveness in heat transfer was depend on percentage of mixture between ethylene glycol and water. How the percentage of mixture between ethylene glycol and water influencing the cooling effect was the question. Thus, the comparative study of effectiveness between glycol and water as a refrigerant medium were conducted in this paper by experimental method. This experiment was carried out by using an evaporative coil model at reduced scales. The medium used were ethylene glycol, water and the mixture of ethylene glycol and water. To identify the relationship between the medium, several parameter were required in these experiment which is the changes of temperature of air that flow through the evaporative coil, temperature of medium and temperature of cooler medium (cold water) base on the percentage of medium mixture and time taken of the processes. Cooling efficiency of each medium solutions is also been discussed in this study in order to compare the effectiveness of the medium solution. Meanwhile, the new set of data was provided in this paper to analyse the percentage of medium solution mixture that influence in the cooling efficiency. From the result, the increasing of water percentage in a medium has increased the temperature different and reduced time taken for the cooling effect.
