Simulation Study On Solar Assisted Geothermal Heat Pumps With Solar Thermal Buried Pipe In The Same Well

Baced on the traditional Solar Assisted Geothermal Heat Pumps, we put forward the concept of Solar Assisted Geothermal Heat Pumps with solar thermal buried pipe in the same well, which put the buried pipe of Geothermal Heat Pumps and the pipe of Solar system together in the same well. The Geothermal Heat Pumps system and the Solar system work together in the heating condition. Heating storage is in progress while the Geothermal Heat Pumps absorbe heat from earth, so that the temperature of earth is regulated and the Heat Pumps system failure caused by falling earth temperature will be avoided.We put forward the basic system of Solar Assisted Geothermal Heat Pumps with solar thermal buried pipe in the same well, and mainly analysis the thermal storage of earth in heating condition and the logic of changing temperature distribution around the buried pipes. Different opration modes were offered in different period of heating condition, based on the practical building heat load, compared with traditional Geothermal Heat Pumps. Opration modes of the new system will focus on the actural condition of office building.We can safely draw the conclusion that compared with traditional Geothermal Heat Pumps, the system of Solar Assisted Geothermal Heat Pumps with solar thermal buried pipe in the same well will make contributions to avoid the Heat Pumps system failure caused by falling earth temperature by regulating temperature of earth with endothermic and exothermic process at the same time. Also it has variety opration modes for office building in heating condition.
