The purpose of this paper is to investigate supply air conditions and energy saving potentials of a dedicated outdoor air system (DOAS) applied to a patient room of health care facilities. The design of HVAC systems for healthcare facilities is a specialized field of engineering. Based on the current health care facilities design satandards, it was assumed that four 25.8m2 unit patient rooms are served by the three different HVAC systems; a constant air volume system(CAV) with fan coil unit(FCU), a variable air volume system (VAV), and a dedicated outdoor air system (DOAS) with fan coil unit (FCU). Control strategies and energy saving potentials of each system were modeled and estimated using the TRNSYS 16 energy simulation program. Annual cooling and heating coil loads and fan energy reduction were calculated. It was found that the DOAS+FCU system can reduce the fan energy consumption over 65% annually compared with the conventional CAV+FCU system. In addition, over 57.5% of annual cooling coil load can be reduced by use of DOAS+FCU system. |
