Climate Control

Heating, ventilation, and air conditioning

Heating, ventilation, and air conditioning systems regulate temperature, humidity, and indoor air quality in vehicles and buildings. They are designed to provide thermal comfort and to control airborne contaminants through heating, cooling, ventilation, filtration, and humidity control. HVAC design considerations include energy efficiency, indoor air quality, maintenance, and environmental impact, particularly in green building projects. In building design, mechanical, electrical, and plumbing engineers may integrate HVAC systems with other building systems and use energy modeling to evaluate performance and operating costs.

Climate

Climate is the long-term weather pattern in a region, typically averaged over 30 years. More rigorously, it is the mean and variability of meteorological variables over a time spanning from months to millions of years. Some of the meteorological variables that are commonly measured are temperature, humidity, atmospheric pressure, wind, and precipitation. In a broader sense, climate is the state of the components of the climate system, including the atmosphere, hydrosphere, cryosphere, lithosphere and biosphere and the interactions between them. The climate of a location is affected by its latitude, longitude, terrain, altitude, land use and nearby water bodies and their currents.
