For hotels located in the tropical climate, a significant amount of energy is attributed to the space cooling and the domestic hot water (DHW) usage. To improve the energy efficiency of hotels in the tropical climate, we proposed a heat recovery system that could utilize the waste heat from the space cooling to preheat the city water supplied to the DHW system . To support the system design, we selected Modelica to model the heat recovery system and its control, which is difficult to be simulated by conventional building simulation tools. The Modelica Buildings library and the Modelica_StateGraph2 library were employed to build the system model. A hotel in Miami, USA, was selected for the case study. The simulation results showed that the proposed heat recovery system could save up to around 30% boiler energy use in the DHW system.
