Heating, Ventillation, and Air-conditioning
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. Management of these components may be critical within agricultural structures. Heating, ventilation, and air-conditioning are used to modify the natural environment to reduce the environmental stress of animals and biological products.
