EXPERIMENTAL MEASUREMENTS OF GRAVITY HEAT PIPE WITH NH3 MEDIUM TO OBTAIN LOW-POTENTIAL GEOTHERMAL HEAT
Journal Title: Structure and Environment - Year 2018, Vol 0, Issue 1
Abstract
Earth / water heat pumps using vertical heat exchangers do not require large areas and do not depend on the intensity of the sun’s radiation that strikes the surface of the earth. Vertical heat exchangers work efficiently in virtually all geological environments, except for low thermal conductivity soils such as dry sand or dry gravel. As the forced circulation media is selected anti-freeze mixtures with water in proportion to the requirements of the operating conditions. Circulation of the working medium in the deep hole requires circulation pump. The paper presents a design of equipment for the usage of lowpotential heat collected from rock in a deep borehole by means of heat pipes (HP). Part of the paper deals with the processing of measurement results gathered from the comparative experimental equipment requiring forced and unforced circulation (heat pipe) of the working substance on the primary side of the heat pump.

FID SIGNAL INTENSITY IN THE NMR STUDIES OF COHESIVE SOILS AT THE POSITIVE TEMPERATURE RANGE
The purpose of this study was to explain the reason of the FID signal intensity change for soil samples in the positive temperature range (0-40°C). According to the reference data the main cause is the presence of the pa...
