Training Course: Heating, Ventilation & Conditioning (HVAC)

Introduction

Heating, Ventilation, and Air Conditioning (HVAC) is a critical system used to control the indoor environment of residential, commercial, and industrial buildings. Its primary goals are to maintain optimal indoor air quality (IAQ) and thermal comfort. HVAC systems are essential for regulating air quality, temperature, humidity, and pressurization, which can impact the health and productivity of occupants. The HVAC industry also focuses on energy efficiency, sustainability, and maintaining a clean environment, especially in medical and computer rooms where precise control of air and temperature is paramount.
