Heating, Ventilation & Air Conditioning (HVAC) for Hospital Event, 13.Jan.2025

Introduction

Heating, ventilation, and air conditioning (HVAC) is an indoor and vehicular environmental comforting technology. The technology aims to provide thermal comfort and high indoor air quality. The techniques of ventilating a building is further divided into a few types as mechanical, forced, and natural ventilation that will provide optimal temperature throughout the day and night.
Today in hospitals, HVAC systems are witnessed everywhere despite the type of environment including domestic and commercial. HVAC systems offer ventilation and balances pressure between vacuum spaces. This method of delivering air and removing spaces is called as room air distribution.
