42、e, latent, and other functions of an HMC system be decoupled? By ibrahim B. Kilkis, Ph.D.; Selim R. Suntur; and Meric Sapci Member ASHRAE Life Member ASHRAE D uring the technological evolu- tion for human comfort, indoor heating was identified first. An important late 19th century development was th

43、e widespread use of central heating systems. These systems had only one function; to transfer sensible heat to indoor spaces. Industrial necessity, rather than a desire to improve human comfort, prompted the early recognition of other indoor require- ments. Willis Carrier developed a humidity contro

44、l device in 1902 for a lithographic and publishing plant to preserve paper from,the effects of excess humidity. Later, indoor humidity control and comfort cooling were determined to improve the factory produc- tivity by about 51% in a factory. Soon after, new HVAC components such as cooling, ventila

45、tion, humidity con- trol and indoor air quality assurance were defined. In the meantime, buildings became function specific, and their special indoor requirements were also identified. Radiant Temperature Asymmetry, Vertical Air Tem- perature Profile, Operative Temperature (OT), Mean Radiant Tempera

46、ture (MRT), Effective Radiant Flux (ERF), air velocity, and Turbulence Intensity (Tu); are especially important for spaces with special functions like offices, schools, hospitals, museums and libraries. As a consequence of new comfort vec- tors and indoor air quality requirements, new functions were

47、 superimposed on the sensible heat transfer. In other words, while The Ankara Museum of Ethnography in Ankara, Turkey diverse functions were identified and assigned, the central forced-air system even- tudy became a multi-function system. This concept of coupling the HVAC functions at the plant, dis

48、tribution, and delivery levels dominated the industry until recently. Diver- sity of HVAC functions, and the precise control requirements now call for the relief of a single and “overloaded” central system from performing too many tasks simul- taneously. When the sensible, latent, and other function

49、s are decoupled; it becomes possi- ble to employ more function-specialized, dedicated and alternative distribution and delivery systems. Increase in efficiency, system agiiity, and response flexibility are the benefits which are indicated by the follow- ing factors. Human thermal comfort Recent studies have indicated a stronger relationship between thermal com- fort, and Mean Radiant Temperature, Operative Temperature and Radiant Asym- metry. While an air system cannot directly control the Mean Radiant T
