Abstract


This study aims to compare the effect of variations in the refrigerator heat exchanger installation of
cooling capacity and refrigerant mass flow rate. Tests performed on the test section consists of two
types of heat exchangers, Suction-Liquid Heat Exchanger (SLHX) and Tube in Tube Heat Exchanger
(TiTHX). Test data measured at the temperature of the cooling load temperature of 60C to - 60C and
the working fluid is used as a cooling medium is a refrigerant 12. As a result, it was obtained that in
this research was cooling capacity by a refrigeration system that uses TiTHX 0.6% greater than the
refrigeration system that uses SLHX. This is due to there is little difference between the temperature of
evaporation and temperature liquid refrigerant that will go into the expansion device on a system that
uses TiTHX than refrigeration systems that use SLHX. The amount of refrigerant is circulated 0.6%
less on a system that uses TiTHX than systems that use SLHX.
