![]() Because of this, the residential sector has enormous potential to be a key player in the future of grid management. Powell, in Computer Aided Chemical Engineering, 2018 1 IntroductionĪir conditioning systems in residential houses consume big amounts of electricity and is usually accompanied with peak demand issues. Read moreġ3th International Symposium on Process Systems Engineering (PSE 2018) HVAC systems range in complexity from stand-alone units that serve individual rooms or zones to large centrally controlled systems serving multiple zones in a building or complex. ![]() On smaller projects, electricity is often used for heating although some systems now use a combination of transfer media. ![]() The two main transfer mediums for this purpose are air and water, which take them to emitters. The most common classification of HVAC systems is by the carrying mediums used to heat or cool a building. In order to service the specific needs, there are a number of different types of HVAC systems available (e.g., single zone/multiple zone, constant volume/variable air volume). And while there are a wide variety of HVAC systems in use in today’s real estate, no system is right for every application. Forced air systems use a fan to push air through a duct system where it is conditioned by a coil on a furnace or air handler before being returned to the space. Radiant Systems usually involve running hot or CHW through pipes that loop around the structure and radiate into the conditioned space via a floor surface or radiator pipe. The first method is using a radiant system, the second is using a forced air system. There are basically two approaches to conditioning a room or building. Therefore, most business or government agency have the potential to realize significant savings by improving their control of HVAC operations and improving the efficiency of the system they use. HVAC systems account for an estimated 39% of the energy currently used in commercial buildings in the United States.
