ANALISIS VARIASI TIPE EVAPORATOR DENGAN REFRIGERAN LPG TERHADAP UNJUK KERJA MESIN REFRIGERATOR
Abstract: Refrigeration system
is a system working for cooling temperature some goods or room with absorbs the
heat. Refrigeration process is very important for store a food and beverage so
will be able to keeep up in certain time, refrigerator development has achieve
characteristic improvement about non-ODP (Ozone Depleting Potential) and
non-GWP (Global Warming Potential) refrigerant as well as alternative
refrigerant until now. The purpose of this research is to know about effect
from variation evaporator type using LPG refrigerant againts refrigerator
performance. Experimental methode did for the direct test to analyzed how much
effect from variation evaporator type that are used in (serries one space, ser
series two space, parallel one space, and parallel two space) useing C plate
evaporator and compressor ¾ pk . This research are do it by installing an
evaporator in each unit of refrigerator chamber top part and refrigerator
chamber bottom part that arranged by series and parallel which is in each
chamber have a breaker or without breaker. The result from the research
variation of evaporator type for refrigerator is to know how much the effect of
refrigeration, compression working, refrigeration capacity, and
Coefficient Of Performance (COP). The lowest temperature is shown from
evaporator type series one space, that have a value -21,2 OC. The lowest
interval from both of chamber type is shown from evaporator type parallel two
space, that have a value 3,64 OC. Coefficient Of Performance (COP) from series
type is 9,06 for one space and 9,01 for two space, then from parallel type is
10,59 for one space and 13,43 for two space. Based from research the acquired
result that is from using evaporator series type and parallel type is could be
used for cooling down several room in refrigerator.
