Mechanical Ventilation And Air Conditioning System

As it is a positive means of ventilation it can control the odors contaminants and humidity as well.

Mechanical ventilation and air conditioning system.

In commercial buildings outside air is usually pumped in through heating ventilating and air conditioning hvac systems. In homes outside air gets in through open windows and doors in addition. Mechanical ventilation is also called forced or induced ventilation and is done by fans and other mechanical means. Heat recovery is a method which is increasingly used to reduce the heating and cooling demands of buildings.

Heating ventilation and air conditioning hvac is the technology of indoor and vehicular environmental comfort. By recovering the residual heat in the exhaust gas the fresh air introduced into the air conditioning system is pre heated and the fresh air enthalpy is increased before the fresh air enters the room or the air. Hvac systems are among the largest energy consumers in schools. Heat recovery ventilation also known as mechanical ventilation heat recovery is an energy recovery ventilation system which works between two sources at different temperatures.

There are many examples of mechanical ventilation like our kitchens and bathrooms that have exhaust fans. The main purposes of a heating ventilation and air conditioning hvac system are to help maintain good indoor air quality through adequate ventilation with filtration and provide thermal comfort. This means of ventilation is very effective in controlling the humidity and air quality inside an air conditioned space. Hvac system design is a subdiscipline of mechanical engineering based on the principles of thermodynamics fluid mechanics and heat transfer.
