Using HVAC Systems in Buildings for Temperature Control

Construction Tech Review | Tuesday, May 10, 2022

In chemical processing, pharma, and food processing facilities, effective flow management is required by heating, ventilation, and air conditioning (HVAC) systems.

Fremont, CA:HVAC and ventilation systems play a critical role in chemical, biomedical, and food processing plants, but these sophisticated devices are sometimes neglected. Many processing plant buildings, rooms, and infrastructure are being air-conditioned. Many of these institutions' structures, work areas, or enclosures require some form of an HVAC system. Some require complex ventilation for temperature modifications as well as other process and operational requirements, including cleaning and sterilization, while others may merely require HVAC for staff and operators. There are also enclosures and structures where large amounts of heat are released, necessitating special heat dissipation and temperature management facilities.

The purpose of heating, ventilation, and air conditioning is to promote thermal comfort and good indoor air quality. Fluid mechanics, thermodynamics, and heat transfer principles all play a role in HVAC system architecture. Temperature management, oxygen refill, and the removal of moisture, smells, smoke, heat, dust, airborne bacteria, carbon dioxide, and other contaminants are all part of the ventilation process. Ventilation removes odors and pollutants, introduces outside air (after filtration), circulates interior air, and prevents air stagnation.

Any air-conditioning system requires fresh air makeup. It should be filtered, temperature-controlled, and then correctly delivered into the indoor space, creating a positive force in buildings, rooms, or enclosures. The exhaust air should be positioned properly so that it does not enter any air-conditioning air vents.

Different standards and guidelines exist for HVAC systems; however, the American Society of Heating, Refrigerating, and Air-Conditioning Engineers (ASHRAE) has produced a standardized set of standards that are extensively used globally.
