Abstract
An experimental investigation was carried out with a view of a coefficient of performance and energy saving in a vehicle air-conditioning (AC) system. The experimental set-up consists of original components from the airconditioningsystem of a compact passenger vehicle. The compressor working with the fluids HFC-134a and HC-134a and has been tested varying the speed in the range 1000, 1500, 2000 and 2500 rpm. The measurements taken during the one hour experimental periods at 2-minutes interval times for temperature setpoint of 20oC with internal heat load 1000 W. The experimental results showed that the COP and energy saving of HC-134a higher than that of HFC-134a.Downloads
