KAJI EKSPERIMENTAL PENGARUH PERUBAHAN TEMPERATUR KELUAR EVAPORATOR TERHADAP UNJUK KERJA KOMPRESOR ROTARY (SANYO C1R55H4C)AIR COOLED CHILLER DENGAN REFRIGERAN R-22 PADA TEMPERATUR KELUAR KONDENSOR 28C

Abstract

The Technology of refrigeration and the air condition are one of technology that very required by human being. The air condition with the system indirectly is one of the solution to take care of the security of systems refrigeration from leakage refrigerant, where with this systems emiting a stream of in coresponding pipe in room is water, this systems we recognize with Air Cooled Chiller. Air-Cooled Chiller is the systems of room refrigeration where water are the refrigerant sekunder which have been made cool in evaporator. At this evaporator is happened the heat transfer which have low temperature, where water made cool by refrigerant. After that, the water conducted with the pump into coil cooler, that referred as FCU ( fan of unit coil ) to make cool the room. The study of eksperimental conducted at this systems Air Cooled Chiller use the refrigerant R-22 with the variation of temperature go out from evaporator and take care of constant of temperature go out from condensor at position 280C. This matter is aim to know the performance of Air Cooled Chiller systems by using refrigerant R-22. Besides that the examination is aim to know the process of cycle compretion condense that happened at this systems. Result obtained from this examination is with the existence of burden refrigeration become greater, the go out of temperature from evaporator ( T1) will go up, so with the increase of T1 the permormance or COP from this machine also being of increase.
