ADVANCE HVAC: HVAC DESIGNING FOR HEALTH CARE FACILATIES

Explore how US FDA standards shape the design of pharmaceutical facilities, with a focus on HVAC and ventilation to meet safety, quality, and public health requirements.

Control airborne particles, dust, and microorganisms with high-efficiency filtration. Maintain positive pressure, humidity with dehumidifiers, and temperature with chillers to support clean pharmaceutical areas.

Identify what particulates are and how air carries solid particles, bacteria, and gases as contaminants. Distinguish external and internal sources of particulates and their implications for pharmaceutical HVAC.

Understand how pharmaceutical clean rooms control temperature, relative humidity, and airborne 0.5 micron particles to maintain cleanliness, with classification by particle concentration in a cubic meter of air.

Explore US federal cleanroom standards, classifying by particle counts (class 100, 1000, 10,000) for 0.5 micron particles, and compare to European grades A, B, C, D and their limits.

Explain how air changes per hour measure how air is replaced in health care facilities, by supplying fresh air and exhausting air, and how these rates influence load calculations.

Focuses on temperature and humidity for pharmaceutical HVAC design, detailing room temperature 67–77 Fahrenheit with a 72 Fahrenheit control point and humidity targets around 40–60% (often 50 ± 5%).

Insert a Revit file into a project using the link Revit option, then bind and view it in 3D. Set levels, define slope, and apply architecture and mechanical templates.

Execute a practical project by loading a mechanical template, linking a Revit file, and binding links to toggle between architecture and mechanical views in 3D.

Select the project location via the location tab, with options for default city list or mapping services, showing Istanbul, Turkey's latitude, longitude, and yearly weather data; then enter project information.

Improve safety and indoor air quality in healthcare facilities by controlling temperature and humidity, diluting contaminants with ventilation and filtration, and preventing cross-department air movement to minimize airborne pathogen transmission.

Prevent infection in health care facilities by controlling air movement and eliminating contact, droplet, and airborne transmission between areas.

Explore isolation rooms in health care facilities, including airborne infection isolation rooms and protective environment rooms, with emphasis on air handling, ventilation, and filtration to reduce transmission.

Explains protective environment isolation rooms for immunocompromised patients, using HEPA-filtered fresh air and controlled air exchange to protect those with HIV, cancer, diabetes, or on immunosuppressive therapy.

Explain how the classification of isolation rooms affects HVAC design by comparing protective environments with isolation rooms, emphasizing positive versus negative pressure, hourly air exchange above 12, and HEPA filtration.

Identify factors that affect local particle concentration around a person in isolation rooms, including production rate, supply and exhaust matched to room size, filtration quality, and air distribution.

Explain general ventilation and more than 12 air changes per hour. Detail filtration with high-efficiency filters removing 99.99% of airborne particles and local exhaust ventilation or source control.

Explore negative pressure isolation rooms to prevent contaminant transfer by manipulating supply and exhaust air through an internal airlock, achieving higher negative pressure in patient rooms than in the corridor.

Learn infection control and ventilation requirements for airborne infectious isolation rooms by maintaining continuous negative pressure, ensuring proper air changes per hour, and applying MERV 14 and HEPA filtration.

Place ceiling supply diffusers at the perimeter near entry. Exhaust six inches above the floor, independent from the building's common system, with constant-volume, terminal HEPA makeup air and monitoring.

Ensure infection-control and ventilation for AII rooms by achieving airtight seals with proper window and door construction, monitoring leakage, installing self-closing doors, and providing handwash and respiratory protection.

Direct air from AII rooms outdoors away from intakes and populated areas, avoiding recirculation. Use HEPA and UVGI in exhaust ducts as supplemental cleaning, not as a HEPA substitute.
