Lyakhovetskaya-Tokareva M. Increase of efficiency of use of natural cold in systems of microclimate

The thesis is devoted to solving the problem of increasing energy efficiency in climate , based on the use of natural cold outside air and low-temperature potential of the soil. Developed a year-round cooling technology system of civil and industrial buildings, functional features which are based on the methods of rational use of Refrigeration ( chiller ) , natural cold air and low potential energy of the soil. A conceptual model of technological methods of rational use of energy resources , including non-traditional in cooling systems in the warm season , the transition and the cold period of the year. On the basis of mathematical models of cooling water and heating under the action taken by the water temperature factors and temperature derived analytical expressions , allowing to determine the temperature of the water cooled in the nozzle chamber , depending on the input parameters of air and water. Based on the exergy analysis of the processes taking place in the chiller temperature changes of evaporation and condensation temperature , the values of exergy efficiency ratio of a system operating under different operating conditions of the system.
