Hospitals are feeling pressure to improve the patient experience. ASHRAE/ASHE Standard 170 allows various HVAC design alternatives including legacy overhead mixing, displacement ventilation, active chilled beams, and radiant heating and cooling systems. This session compares the performance of each design option and sensible cooling loads for a typical patient room. Insights into the thermal comfort of patients and probable flow of airborne pathogens will be given as well as advice for the selection of appropriate HVAC systems for patient rooms.
1.) Explain the importance of airflow distribution in a patient room.
2.) Explore the impact of HVAC design on thermal comfort of patients.
3.) Discover how HVAC design affects flow path of airborne pathogens.
4.) Compare the performance of various HVAC design alternatives for patient rooms.
