| Description
| - Přenos tepla z potraviny vložené do chladicí vitriny je kombinací přirozené konvekce, vedení a radiace. Tyto tři mechanismy byly analyzovány teoreticky pro jednoduché tvary chlazených produktů a experimentálně, použitím přesných kovových odlitků salátových kelímků. Byl sledován nejen vliv geometrie, ale především vliv vzájemného uspořádání většího množství vzorků o různých teplotách. Z monitorovaných časových průběhů teplot vzorků a vzduchu v chladicí vitrině byly dopočteny efektivní hodnoty součinitele přenostu tepla a navrženy odpovídající korelace. (cs)
- Calculations of transient temperatures of food products after they are transferred from a warm environment into a display cabinet, require data on the surface heat transfer coefficient (SHTC). There is no forced air flow in an ordinary display cabinet, so the energy transfer is achieved mainly by free convection, conduction to a supporting plate, and radiation. Theoretical analysis of the heat transfer to a cylindrical sample demonstrates the relative influences of these mechanisms. This work investigates the apparent surface transfer coefficients with metal models. Heated models were placed individually (bare) in containers with and without lids. Each model was surrounded by identical containers filled with water. These were initially at the same temperature as the model or at the mean cabinet temperature. There were one, two, or three layers of these water containers. From the measured time-temperature histories of the model and
