Simulation of geothermal pump

[摘要] The use of geothermal pumps allows one to reduce the load on the energy complex. For practice it is interesting for the conditions of a moderate climate, to reveal the most effective means of the organization of heat pump installations. The paper describes the main features of the use of heat pumps. The mathematical simulation of the geothermal circuit is given. The work of geothermal contours of different types is investigated. The efficiency of using a dead-end coaxial probe in a heat pump unit with direct boiling of the refrigerant is inferior to a U-shaped heat exchanger from standard pipes. The results of the paper can be useful in the development of prospective sources, using geothermal energy.
