Abstract

Vapour compression refrigeration is one of many refrigeration cycles available for use. The vapour compression refrigeration system uses a circulating liquid refrigerant as the medium which absorbs and remove heat from the space to be coolled and subsequently rejects that heat elsewhere. One of component that important in this cycle is expansion valve. Function of expansion valve are to reduce pressure and set the stream of refrigerant to the evaporator. This research was focused to know performance and characteristic engine cooling by using the expansion valve and capilary as a means of expansion tools. Obtained from experiment results that the value of performance engine cooling by using expansion valve is better than capilary. Coefficient of Performance (COP) with the expansion valve is between 3.4 – 7.53, while the capillary is between 2.8 – 3.6.
