Development of Split Air-Conditioning System using Chill Water as the Cooling Medium
Current air conditioning system is using refrigerant as
the cooling medium. The main purpose of this study is to develop an
air conditioning system using chill water as the cooling medium. In
this system, chill water used to replace refrigerant as the cooling
medium. This study is focus on the split type unit air conditioning
system only. It will be involving some renovation on the indoor unit
and freezer. The cooling capability of this system was validate by few
series of testing, which conducted at standard 36m3 office room.
Result of the testing found that 0.1 m3 of chill water is able to
maintain the room temperature within standard up to 4 ~ 8 hours. It
expected able to maintain room temperature up to 10 hour with some
