Modelling and Simulation of Dynamic Behaviour of Refrigerated Products in a Cold Storage Room

The presented paper describes the development of mathematical model suitable for calculating temperature and humidity response and for simulation of dynamic behaviour of refrigerated products in a cold storage room. Moist air, circulating around refrigerated products within cold chamber is continuously in direct contact with surface of the goods. Simultaneous heat and mass exchange occurs between refrigerated goods and moist air. During such process mass exchange is considered as evaporation at the product surface exposed to air circulation. Only top surface of the product is therefore drying. This paper is limited to consideration of drying of surface moisture, but not the hygroscopic moisture. Developed mathematical model, describing the dynamic changes of temperature and humidity of refrigerated goods caused by multiple influential factors, is based on mass and energy balances. Such model provides simulation of dynamic behaviour of refrigerated product between temperature ranges of above and below 0°C (including 0°C).
