Abstract
Modular chiller is a central Air
Conditioning (AC) system, which consists of several modules that work together to reject the heat that
absorbed by the chilled water from the building to be discharged into the environment. Chiller type is also a
solution for the efficient use of electrical energy due to the number of units in operation can adjust to the
heat load generated by the building. Heat load tends to fluctuate depending on the amount of space used,
the number of electronic tools are used, the number of people in activity, and other heat load factors.
Chiller is operated at setting temperature 6oC. The analysis showed that the actual cooling capacity (QL) in
the evaporator, the actual compressor power (Wk) and the actual waste heat capacity (QH) in the
condenser respectively are 357.5 kW to the total 845 kW cooling capacity availability, 66.1 kW to the total
157 kW of power compressor, and 423.6 kW to the total 1002 kW of the potential heat rejected by
condenser, with COP of the chiller is 5.4. Cooling capacity provided 57.7% greater than the total cooling
capacity actual, so it is more than enough to meet the overall cooling load at the Y hotel, to obtain the
appropriate thermal comfort standard by SNI 03-6572-2001.
