This article deals with estimating a potential and efficiency of utilization of passive ground "cold" for cooling buildings in climatic conditions of Moscow (Russia). The article presents results of numerical analysis to assess the efficiency of reducing peak cooling loads of the building equipped with AGHCS, through the utilization of natural cold of wells for passive cooling and cold storage in summer at night (off-peak) time with its subsequent consumption in the day time, both in passive mode, and with heat pumps. The conclusions of the article set out the basic principles of passive cooling in the design of AGHCS.

Abstract. This article reports results of comparing the accuracy of the software package "INSOLAR.GSHP.12", modeling non-steady thermal behavior of geothermal heat pump heating systems (GHCS) and of the similar model "conventional" using finite difference methods for solving spatial non-steady problems of heat conductivity. The software package is based on the method of formulating mathematical models of thermal behavior of ground low-grade heat collection systems developed by INSOLAR group of companies. Equations of mathematical model of spatial non-steady thermal behavior of ground mass of lowgrade heat collection system obtained by the developed method have been solved analytically that significantly reduced computing time spent by the software complex "INSOLAR.GSHP.12" for calculations. The method allows to turn aside difficulties associated with information uncertainty of mathematical models of the ground thermal behavior and approximation of external factors affecting the ground. Use of experimentally obtained information about the ground natural thermal behavior in the software package allows to partially take into account the whole complex of factors (such as availability of groundwater, their velocity and thermal behavior, structure and arrangement of ground layers, the Earth's thermal background, precipitation, phase transformations of moisture in the pore space, and more), significantly influencing the formation of thermal behavior of the ground mass of a low-grade geothermal heat collection system. Numerical experiments presented in the article confirmed the high convergence of the results obtained through the software package "INSOLAR.GSHP.12" with solutions obtained by conventional finite-difference methods.
