ABSTRACT

In this entry, the winter heating and summer cooling system for a house is described, and is based on a newly developed geothermal heat pump technology. The heat pump serves water stored in an underground tank. During the winter season, the heat pump extracts heat from the water, including phase transition heat. The water in the underground tank during the winter season absorbs geothermal energy from the ground. At the end of winter season, all water in the tank transforms into ice. In the summer season, the stored ice absorbs fusion heat and melts. The resulting cold water is used as a ready source of cold to cool the house without energy consumption. The operation of the system in winter heating and summer air-conditioning of a house is explained. Methods for calculation and design for both heating and cooling systems of the house and suggested types of geothermal heat pump are presented. An analysis of energy efficiency and cost-effectiveness of the system were accomplished. The results of the analysis prove the high efficiency and environmental safety of this system are given.
