چکیده
–The objective of this work is to study the performance of a split air conditioning system with and without a Matrix Heat Exchanger (MHE) .The experiment was done using HFC134a as the refrigerant and Polyol-ester oil (POE) as the conventional lubricant in the air conditioning system. The performance of the split air conditioning system with HFC134a/POE oil system was compared with HFC134a/POE oil/MHE for different load conditions. The result indicates that the system performance has improved when HFC134a/POE oil/MHE system was used instead of HFC134a/POE oil system and there was also a reduction in power consumption at all load conditions. The HFC134a/POE oil/MHE works normally and safely in the air conditioning system. HFC134a/POE mineral oil/MHE system reduced the energy consumption by 33.84% when compared with the HFC134a/POE oil system. There was also an enhancement in coefficient of performance (COP) when MHE was introduced in the normal system. Keywords––Split air conditioner, HFC134a, POE oil, Matrix Heat Exchanger, COP, Vapour Compression System
