Heating, Ventilation, and Air-conditioning

1991
Air is a complex mixture of gases, water vapor, and heat. All living organisms require these three components, but not necessarily in the same proportions. Each organism has an optimum range of all three conditions, and any time the conditions are less than optimum, the organism is stressed.

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

Heating, Ventilating and Air-Conditioning (HVAC)

1992
The indoor work environment must be controlled for comfort and to ensure the proper operation of the equipment within the workplace. Although people may be able to work temporarily in temperatures that deviate from the normal comfort zone, computers and computerized equipment do not have the same degree of adaptability.

HEATING, VENTILATION AND AIR CONDITIONING

HVAC is Heating, Ventilation, and Air Conditioning. HVAC systems control the indoor environment (temperature, humidity, airflow, and air filtering) to condition the air to a preferred temperature and relative humidity. The term HVAC means the entire air system of our living space which determines the indoor air quality.

Intelligent Control of Heating, Ventilating and Air Conditioning Systems

2009
This paper proposed a simulation-optimization energy saving strategy for heating, ventilating and air conditioning (HVAC) systems’ condenser water loop through intelligent control of single speed cooling towers’ components. An analysis of system components has showed the interactions of control variables inside the cooling towers and between the ...
