Experimental study of the impact of the vegetable cold store floor location on heat exchange with the soil
Paweł Sokołowski , Grzegorz Nawalany
AbstractThe paper analyses the impact of location of the vegetable cold store floor in relation to the ground level on heat exchange with the soil. The scope includes the analysis of indoor and outdoor temperature and soil temperature under the cold store and its surrounding, specification and adaptation of the cold store heat exchange model with soil, calculations for chosen variants in non-stationary conditions and a comparative analysis of cold store heat exchange with soil and soil temperature in chosen solutions. The paper used the results of field studies conducted in a cold store located in southern Poland. The said building was used to store carrots from 1 October to 30 June. Three calculation variants were used in order to determine in detail the impact of the chosen factors on heat exchange between the cold store and soil. The calculations were made based on the elementary balances method in WUFI®plus software. The calculation model was validated based on the results of field studies of indoor and outdoor temperature and soil temperature in 5 measurement lines at the depth of 0.05, 0.50, 1.00 and 1.50 m. The obtained validation results showed a very high correlation of measurement data and calculated data and an absence of significant differences. The calculation results for 3 variants showed statistically significant (p < 0.05) differences in both soil temperature and heat exchange with the soil.
