| Summary: | The world is growing with ever-increasing energy needs, and in general the electricity supplied to the commercial sector which includes hotels, malls, schools, hospitals and others come from State Electricity Company (PLN). Most of the electricity generated by PLN is sourced from Steam Power Plant which uses coal as the main fuel source. To achieve sustainable, environmentally friendly and inexpensive energy according to the Global Goals, this research will design an air conditioning system in a hotel building, as about 65% of the electrical energy used in a hotel building is consumed by the air conditioning system.
The estimated results of the cooling load on the hotel building are 1397.5 kW for the peak load and 195.7 kW for the minimum load. The load has been compared with the quality standard where the load is in an acceptable condition between low (Lo) and average (Av). The peak load is used in selecting systems and equipment in the HVAC system. In this design, several parameters related to chillers with constant discharges (alternative 1), chillers with varying discharges (alternative 2), chillers with magnetic bearings (alternative 3) and VRF machines (alternative 4) will be compared.
From the calculation results, it is obtained that the chiller with varying discharge, namely alternative 2, has the lowest Energy Consumption Intensity (ECI) valued at 154.44 kWh/m2 which falls within the economical category. Alternative 2 also has the best total life cycle cost compared to the other alternatives, namely Rp.46,082,076,471.00. Thus in the design of air conditioning system for hotel buildings in Batam, alternative 2 is the best choice in comparison to the others.
