There are certain standards and application codes that need to be followed for the design, construction and maintenance of air conditioning installations in hospitals. These standards are applied to the HVAC (Heating, Ventilation, Air Conditioning) systems in hospitals because they not only maintain comfortable climate conditions of temperature and control humidity but also maintain a clean, germ-free environment that contributes to the well-being of patients and spread of diseases.

In a hospital, it is important for the healthcare organizations to provide different types of rooms to patients with different types of pathologies. Such as patients having infectious and Airborne diseases will have to be isolated and patients having other diseases and a weak immune system will have to be kept in separate rooms and areas. As a result, hospitals have a much higher concentration of pathogens than the average building, and most of these agents travel in the air currents, making air conditioning equipment particularly susceptible to accumulating large amounts of pathogens and even serving as breeding grounds for them, posing a health risk to users. All of this may be avoided by properly designing the facilities so that patients, hospital staff, and visitors are not exposed to germs.

With the onset of the annual cold and flu seasons, as well as an increase in COVID-19 cases across the country, it is critical for health care facilities to review their heating, ventilation, and air conditioning (HVAC) systems in order to take preventative measures to reduce the spread of airborne infectious diseases. Because flu viruses are airborne and extremely infectious, occupant space characteristics such as temperature and humidity have a significant impact on how long flu and other airborne viruses may live and move. HVAC systems are important for ensuring a healthy and safe tenant area in addition to providing comfort. Indoor air quality is maintained by HVAC systems.
