ABSTRACT
The authors have developed an improved version of the vapor compression system for heating and cooling civil buildings on the basis of the soil and ventilation air integrated energy. It is characterized by increased energy efficiency and the possibility of redistribution with automatic regulation of generated heat in subsystems. The results of the analytical study of the system established a multifactorial dependence of the actual conversion factor and led to greater efficiency in the transformation of the extracted heat from the soil and ventilation air. It simulates the multifactorial effect of the initial parameters and operating conditions on the possibility of highly efficient use of integrated energy in cold, warm and transitional periods of the year. The integrated use of soil energy and air flows in heat pump heating systems is distinguished by the possibility of its controlled redistribution with a decrease in the intensity of heat extraction via a ground heat exchanger, as well as the possibility of reducing the depth of the wells and the corresponding costs for the arrangement and operation of probe heat exchangers.
