TRANSIENT ANALYSIS OF AIR-CONDITIONING LOAD AND ROOM CONDITIONS CONSIDERING SIMULTANEOUS HEAT AND MOISTURE TRANSPORT OF MULTILAYERED CONSTRUCTIONS

Moisture transport in a building has a major role in condensation problems. It also has much importance in the formation of room air humidity and air-conditioning load. The focal point of this paper is to evaluate room air humidity and air-conditioning load considering moisture transport by desorption and absorption of multi-layered constructions. For this purpose, a computer code has been developed. A brief description of the calculation method and the mathematical background is given. Validation of the procedure is carried out by comparing measured and simulated humidity and temperatures. Simulated examples are shown with the results that the sorption effect keeps air humidity of a storehouse stable and increases air-conditioning loads of an ordinary office room by about 5%.
