HEAT ACCUMULATION IN HELIUM GROUND SYSTEMS IN HEAT PUMP SUPPLY

Problem statement. The paper discusses the problem of estimation of prospects of heat accumulation in the combined systems of heat supply with the use of low potential energy of renewable sources (sun and ground) and heat pumps for increase of their potential. Results and conclusions. The use of heat accumulators in combined heating systems that utilize low-potential solar and ground energy as primary energy sources and heat pumps to boost the potential of the latter was discussed. A method of calculating ground heat exchangers that use the heat pump cycle to increase a thermal potential of renewable energy sources was set forth. An attempt was made at addressing the problem of heat and mass transfer in ground when ground accumulators like "a Field's tube" are used: a geothermal circulation system comprises two wells (pumping and operational).
