HVAC (Operation & Maintenance)

Heating, Ventilation, Air conditioning Controls temperature, humidity and air quality inside a building Especially important in medium to large buildings such as office/residential towers All preferably integrated into one system In warm climates usually no need for a heating system. Heating Central heating often used in cold climates to heat private houses and public buildings Heating systems usually comprise of a boiler, furnace, heat pump or district hot water to heat water, steam or air Piping distributes heated fluid and radiators transfer this heat to air and structures, e.g. floor heating system. Ventilation The process of changing or replacing air in any Space to control temperature or remove moisture, smoke, carbon dioxide, etc Ventilation includes both the exchange of air to the outside as well as circulation of air within the building One of the most important factors for maintaining acceptable indoor air quality in buildings Supply air used for ventilation is filtered and cooled and/or heated inside air handling units. Air Conditioning Refers to the cooling and dehumidification of indoor Air for thermal comfort Air conditioning systems are designed to stabilize the air temperature and humidity within an area Excess heat from the circulating air is usually removed by a cooling coil that is supplied with cold water To decrease relative humidity the circulating air needs to be cooled to a temperature below the dew point and then heated back to meet the requirement.
