Recently hospitals have consumed tremendous energy approximately twice compared to general buildings all over the world. HVAC (Heating, Ventilation and Air Conditioning) systems are the major parts of energy consumption in hospitals. This research evaluates energy consumption characteristics of HVAC systems, with the aim of establishing a common idea for the analysis of hospital building energy efficiency. The objective of this study is to evaluate four different types of HVAC system applied to patient rooms located at three different climate regions that may be used by engineers and designers to assess the effectiveness of HVAC systems. Because of a recommended minimum outdoor air change rate for healthcare facilities, the energy consumption increases. Two all-air system (CAV and VAV) and two water-air system (FCU and active chilled beam with DOAS) were selected by investigating the design cases. In this paper, the HVAC system is evaluated for a patient room using TRNSYS joint with a system design process and simplified system's energy evaluation methodologies. It was found that the active chilled beam with DOAS can be reduced the primary energy by approximately 20% compare with CAV system. Furthermore the study found that dominant factor can be reduced the energy of HVAC system in hospital facilities was how to decrease the OA load. |
