Heating in HVAC

This is one of the essential functions of HVAC. If you are cold and frozen, the heating component helps you to warm and heat your room. Your mind fails to work if you are feeling cold. It is especially useful if you stay in a cold place or during winters. The heating system is usually of two kinds. One is the local heating and the other is the central heating. Local heating is however, not that widely used because it is not cost effective. Central heating is widely used in private houses and public buildings and offices. Though a complicated process, it is primarily the heat pump, a furnace or a boiler and a radiator that completes the heating system.

Ventilation in HVAC

Did you ever think why do you have ventilators in your house? It helps in better movement of air. Similarly, the function of ventilation in HVAC is to bring in fresh air inside the room or to the building. It takes out the carbon dioxide, the smoke, the odor, the humidity from the room and replaced it with fresh air. Ventilation is also of two kinds. One is the natural ventilation and the other form of ventilation is the mechanical or forced ventilation. In the natural form of ventilation, you do not use electrical appliances or any other external product to take out stale air and to bring in fresh air. In the mechanical or forced ventilation on the other hand, you use fans or exhaust fans or chimneys and several other such tools to replace the carbon dioxide filled air and bring in oxygen filled fresh air. In rooms, ceiling or table fans take out the humid air and help you fight perspiration and humidity. In kitchens and bathrooms, most houses have exhaust fans and chimneys to take out the odor filled air and give some relief. Thus, ventilation helps here to keep you healthy and safe.  Especially in attics and lofts, ventilation is absolutely essential to prevent the formation of bacteria and fungi.
