Heating, cooling, ventilating, and process systems serving spaces or providing healthcare functions shall comply with which standard?

The correct answer is related to ASHRAE 170, which specifically addresses the health care facilities' ventilation requirements. This standard outlines the necessary ventilation rates, filtration, and air quality parameters necessary to support various healthcare functions. In settings such as hospitals, clinics, and other medical environments, maintaining appropriate air quality and ventilation is critical to patient health and safety.

ASHRAE 170 includes guidelines tailored for different medical procedures and spaces, ensuring that environments are adequately supplied with outside air and that contaminants are effectively managed. This makes it essential for heating, cooling, ventilating, and process systems serving healthcare functions, as these systems directly influence overall indoor air quality and patient outcomes.

While other standards like ASHRAE 100 focus on energy efficiency in building systems, or ASHRAE 62.1 which pertains to general ventilation for acceptable indoor air quality, they do not specifically target the unique requirements of healthcare facilities in the same way that ASHRAE 170 does. ASHRAE 54 primarily relates to the design of kitchen ventilation systems and is not relevant in the context of healthcare ventilation requirements. Thus, ASHRAE 170 is the appropriate standard for heating, cooling, ventilating, and process systems in healthcare settings
