Abstracts:

Heat pumps for heating the low-rise buildings in Siberia are the real means of energy saving, which provide ecologically safe living conditions. The effectiveness of heat pump application is shown by the comparative analysis with traditional heating systems. The possibility of environment contamination when using the heat pump is caused only by the emissions associated with production of electricity for heat pump operation. The heat pump functioning directly at the site of its installation does not give harmful emissions. The payback period of heat pumps is from 4 to 7 years, and the cost of heat generated by the power plants based on heat pumps is 25-40% lower than the cost of heat of the heating plants. The aim of this work is to study the efficiency of ground heat for heat pump heating of low-rise residential buildings with application of technologies of horizontal and vertical-sloping pipelaying for the low-grade underground heat circuits at the example of natural objects. The paper presents the experimental studies, exergy analysis, and performed thermodynamic calculations. It is shown that the transformation coefficient for the heat pump cycle, using dry ground heat as the low-grade source, is from 4.0 to 4.5, and this is a high index.
