Opis:: The paper is an attempt to determine the impact of soil type and its selected technical parameters on the heat exchange with soil. The test results were based on the all-year-round experimental measurements of soil temperature and indoor and outdoor air in a greenhouse located in southern Poland. The field tests results were used to validate the calculation model using the WUFIplus software. The validation showed a high degree of conformity between the experiments and calculations. Five variants were used in the calculations, differentiated by technical parameters of the soil underneath the greenhouse. The results showed a significant impact of the soil type on the greenhouse energy management.

Opis:: The paper includes an analysis of the impact of the cooling cycle length in vegetable cold stores on the heat exchange with soil. The scope involves the analysis of indoor and outdoor air temperature as well as soil temperature under the cold store and in its vicinity, specification and adaptation of the cold store-soil heat exchange model, model validation by comparison of the calculation results with experimental studies, choice of calculation variants, calculations for the used variants in non-stationary conditions, and a comparative analysis of the cold store-soil heat exchange for the used variants and of the soil temperature at selected solutions. The paper used the results of the field tests conducted in a vegetable cold store located in southern Poland. The building was used to store carrots from 1 October to 30 June. Four calculation variants were used for the in-depth study of the impact of selected factors on the heat exchange between the cold store and the soil. The calculations were performed based on the elementary balances method, using WUFI®plus software. The calculation model validation was based on the field measurements of indoor and outdoor air temperature as well as 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 good correlation between the measured and calculated data, in addition to an absence of significant differences. The calculation results for the 4 calculation variants showed significant differences in the heat exchange with soil.
