EFFECT OF DEPTH AND INSULATION OF A FRUIT COLD STORAGE PLANT FLOOR ON HEAT EXCHANGE WITH THE GROUND
Jan Radoń, Wacław Bieda, Grzegorz Nawalany
ABSTRACT
The method of 3-dimensional, transient heat transfer calculation through partitions touching the ground (floor and walls) was presented. The effect of a fruit cold storage plant floor depth and thermal insulation on heat gains during storage period was analysed. Results of calculations show the great disadvantage of partly underground location and lack of floor insulation of cold storage in comparison with traditional fruit stores. Insulating the floor with foamed polystyrene 10 cm thick reduces total heat gains during the whole cold storage season by as much as about 40% and several times lowers demand of necessary power of cold-storage plant at the beginning of storage period.
Key words: cold-storage plant, ground, thermal insulation, heat transfer.
