Heating, Ventilation and Air-Conditioning

1999
Heating, Ventilation and Air-conditioning, or simply HVAC, can be considered one of the most important services in modern buildings. In the tropical countries, external temperature can be around 35°C on average with a relative humidity up to 90% – 100% in summer. In countries near to the poles, outdoor temperature can be as low — 30°C in winter or even
