Abstract

This paper presents an experimental investigation on the performance of a small size absorption chiller which was renovated or developed from an old out-of-order commercial chiller. Its working fluid and controller circuit was replaced with the new one. The main objectives of this study are to gain the experience and know how to build the absorption chiller. The performance of this developed chiller was investigated under the local weather condition and the concentration of strong solution of 59% was used in this study. The experimental results show that the developed chiller can be operated at about 75% of nominal capacity and this cooling capacity satisfies the cooling load of the current conditioning room. The study results also demonstrate that, to obtain the high coefficient of performance, this chiller should be operated at 85C of hot water temperature supplied to the generator.
