The highest significance in the safekeeping of the biological production has the heat-moister regime in the storehouses and inside of a stored agricultural produce. Existing storage technologies demand certain adjustment in each case, which can be significantly simplified with the computer simulation. The adequate model with realistic conditions can be provided with the complete mathematical description and all basic factors taken into an account. The purpose of this work is the development of the methods of the heat-technical calculation and computer simulation of vegetable storehouses microclimate by solving the conjugate non-stationary heat and moister exchange tasks. The full mathematical model of a heat-exchange is based on the conjugate non-stationary heat-moister exchange task for the whole system construction-equipment-bulk in their heat interconnection, but not for each component separately taking part in the heat-exchange. As a generic math model we consider the heat-moister condition of a semi-sub-surfaced in the ground storehouses, because in this case it's necessary to take into account the heat interaction not only with air surroundings, but also with the ground, unlike above ground surface storehouses as a particular version of common model. Developed the finite-difference method of calculations which have sufficient enough high-speed and accuracy for engineer practice. These methods allow in short time calculate the temperature and moisture in the storehouses. Software package POSOH (Kondrashov, Kondraschov, Kokin, Tyukov, 2003) was designed for computer modeling of these processes. Examples of the simulation for selection of most appropriate construction and technology parameters for reduction of depreciation of agricultural production during storage are provided. The heat-resistant properties of above surface and semi-sub-surfaced storehouses were compared.
