Abstract
The simulations have been carried out for utilization of waste heat recovery from chiller 30RB60 type in hot water needs in hotel. Waste heat recovery from condenser with a capacity of 167 kW is used to heat up 2,500 L volume of water. Based on the simulation results obtained that the average energy can be used for preheating the water was 383,901.221 kJ, to increase the water temperature from 20 oC to 56 oC in 67 minutes, for continually use of chiller. Utilization of waste heat recovery can reduces the use of electric bill until 90%. At the peak ti me ’s utilization of hot water, the simulation result shows that for water consumption up to 400 L in 15 minutes, or 1,600 L/h, the water temperature still kept warm until 4 oC.
