Sažetak
Knowledge of the psychrometric properties of moist air is essential in the design of air conditioning, cold storage, and drying processes. The presented paper describes the development of mathematical model suitable for calculating psychometric properties and for simulation of dynamic behaviour of moist air in refrigerated room. Moist air, circulating around refrigerated product within cold chamber, is continuously in direct contact with surface of the goods, chamber walls, chamber outfit, fans, defrosting coils and evaporator surface. Simultaneous heat and mass exchange occurs between moist air and all elements that air flows by. During the flow within the cold chamber, moist air is simultaneously exposed to all typical changes of state, such as cooling, heating, dehumidification, moistening and mixing with outside air stream caused by door opening and air leakage. Developed mathematical model, describing the dynamics of air temperature and humidity change caused by those multiple influential factors, is based on mass and energy balances. Such model provides calculation of psychometric properties and simulation of dynamic behaviour of unsaturated and saturated moist air between temperature ranges of above and below 0°C (including 0°C).
