HVAC stands for heating, ventilation, and air conditioning. Its basic design enhances vehicular and indoor environmental comfort and promotes overall improved air quality. A sub-discipline of engineering mechanics, HVAC technology is rooted in the conventions of heat transfer and thermodynamics which play incredibly important roles in the construction of structures which house office space, industrial buildings and complexes, such as apartment buildings and high rises, and in the marine environments of aquariums, where healthy (and safe) conditions are strictly regulated apropos of humidity and temperature.
The three main functions of heating, ventilating, and air-conditioning are correlative, especially with the need to enhance environmental comfort and to provide acceptable indoor air quality within reasonable manufacturing, installation and maintenance costs. HVAC systems provide fresh ventilation, reduce malodorous air infiltration, and equalize pressure relationships between neutral spaces. The fluctuation of air between neutral spaces is colloquially known as “room air distribution.”
Explaining Its Most Important Feature-Ventilation
Ventilation is the means by which air is recycled in any enclosed area to control overall room temperature or to remove any combination of odors, smoke, dust, moisture, excessive heat, airborne bacteria, or carbon dioxide, and to replenish stale oxygen. Ventilation includes both the swapping of air with the outside as well as the constant recycling of fresh air within the structure. It is one of the most important factors for maintaining more than acceptable indoor air quality in buildings. Stagnant air can enhance a structure’s susceptibility to carbon monoxide buildup, and HVAC systems are integral in maintaining safe levels of fresh air.
Dangers Of Bad Ventilation
Without appropriate ventilation, carbon monoxide (CO) can be deadly even if inhaled in small doses. Minimal carbon monoxide exposure can induce and abet ailments such as headaches, fatigue, nausea, and concentrated vomiting. Carbon monoxide binds with the blood’s hemoglobin, making carboxyhemoglobin, reducing immensely the blood’s ability to transport oxygen throughout the body. The primary health concerns associated with carbon monoxide exposure are its cardiovascular and effects on the neurosystem. Carbon monoxide can cause hardening of the arteries (atherosclerosis) and can also trigger massive heart attacks and strokes. Neurologically, even minute exposure to carbon monoxide can have a negative affect on hand/eye coordination, alertness, and regular performance. It can also have a disorienting effect.
Natural ventilation greatly reduces the spread of airborne illnesses such as tuberculosis, influenza, meningitis and the common cold. Opening doors, windows, and utilizing ceiling fans are all ways to maximize natural ventilation flow and reduces the risk of airborne contagions from hanging around. Natural ventilation is relatively inexpensive in comparison and easy to maintain.
