Abstract

The hospitality industry in Bali’s tourism sector is experiencing rapid growth, requiring higher efficiency in operational systems, particularly in the hot water supply which is a vital facility for guest comfort. This study evaluates a heat pump unit with a compressor capacity of 87.1 HP implemented at the Aloft Bali Kuta Hotel, which operates 175 guest rooms. Heat pumps are considered more efficient compared to conventional heating systems as they operate based on the thermodynamic cycle, transferring heat to generate hot water with lower energy consumption. The research method consisted of literature studies, interviews with the hotel’s engineering staff, and field observations to collect operational data. Technical analyses were performed to calculate the hotel’s daily hot water demand, the flow rate of the return pump, and the capacity of the transfer pump to the hot water storage tank. The results show that the hotel’s hot water demand is 4,375 liters per day, which matches the available storage tank capacity of 4,500 liters. The return pump flow rate was calculated at 0.91 m³/hour, which aligns with the installed pump capacity of 3 m³/hour. Furthermore, the calculated transfer pump capacity of 0.18 m³/hour was found to be suitable compared to the existing pump specification of 10 m³/hour. In conclusion, the heat pump system applied at Aloft Bali Kuta is proven to be effective, energy-efficient, and supportive of sustainable hotel operations. This study provides valuable technical insights and recommendations that can serve as a reference for hotel management and the hospitality industry in adopting environmentally friendly hot water heating technologies.
