Heat and Mass Transfer of a Coolant in Horizontal Seasonal Cooling Devices

The heat-mass transfer in the seasonal cooling device with air coolant is considered in this article. This device works during the cold period of year at the expense of the difference between temperatures of soil and air. Their thermal calculation which comes down to drawing up thermal balance for determination of temperature of coolant, being its main characteristic is considered. The engineering method of calculation of heat fluxes of the soil and the pipeline laid in the thickness is developed. Also, there were made a natural measurements of the cooling system. Experimental research was made for the purpose of establishment of qualitative and quantitative regularities of communication of the key parameters characterizing operation of the seasonal cooling devices: air temperatures and speeds of its circulation with the defining factors - the air temperature, wind speed, temperature of soil and its heat-physical properties. Results of researches were used also as the actual material during the checking and justification of theoretically determined formulas.
