Snow melting and heating systems based on geothermal heat pumps at Goleniow Airport, Poland

Abstract

A design for a snow melting and heating system for the airport at Goleniow, Poland, is proposed. The system is based on utilization of geothermal energy from the Szczecin region close to Goleniow town. Geothermal water at 40-90°C is found in this area. The system is based on utilization of heat pumps extracting heat from 40 or 60°C hot water. Comparison of the performance of different heat pump arrangements in a heating system for 40°C geothermal fluid is made. Thermal and fluid-flow calculations for the geothermal heat plant are presented here. The production- reinjecting geothermal well system consists of a counter-flow geothermal-heat exchanger and heat pump (electrically driven) with an evaporator located either directly after the geothermal heat exchanger (system 1), or with an evaporator located indirectly on the return network water (system 2). The system also contains a conventional heat source – a peak gas boiler, which can work ...
