Introduction: Heating, ventilation, and air conditioning (HVAC) are the technology of indoor and parking environmental comfort. Its goal is to provide thermal comfort and acceptable indoor air quality (IAQ). H.V.A.C system design is a sub-discipline of mechanical engineering, based on the principles of Thermodynamics (TD), Fluid Mechanics (FM) and Heat Transfer.
Heating - is often used in winter season (i.e. cold climate) to heat private houses or commercial buildings etc. Heaters are mechanism whose purpose is to produce heat (i.e. warmth) the building. This can be done via central heating. Heating systems usually comprise of a boiler, furnace or heat pump to heat water, steam, or air in a central location such as a furnace room in a home, or a mechanical room in a large building. There is a three modes of heat transferred i.e. conduction, convection and radiation.
Ventilation - is the way of changing or replacing natural air in any space to control temperature or eliminate any combination of moisture, odors, smoke, heat, dust, airborne bacteria, or carbon dioxide, and to return oxygen. Ventilation process includes both the interchange of air with the outside as well as circulation of air within the building. It is one of the most important factors for maintaining acceptable indoor air quality (IAQ) in buildings. Two types of ventilation methods are used Mechanical (Forced) and Natural Ventilation types.
Air conditioning - (Referred to as A/C) is the process of removing heat and moisture from the interior of an occupied space, to improve the comfort of occupants. A/C can be used in both domestic and commercial environments. An air-conditioning system provides cooling and humidity management for all or part of a building. Air conditioned buildings typically have sealed windows, as a result of open windows would work against the system supposed to keep up constant indoor air conditions. Outside, fresh air is mostly drawn into the system by a vent into the indoor heat exchanger section, creating positive air pressure. The percentage of return air made up of fresh air can usually be manipulated by adjusting the opening of this vent. Typical fresh air intake is about10%-15%. M.S. Institute of Engineering is fasted growing institute in Hyderabad to provide HVAC and all other related. We are having the best teachers and they have field experience. We are also assisting our students to get the job in India and Abroad.
