Résumé

A novel conception for energy use was presented, the natural cold energy in the air in winter in cold climates was stored in ground and then extracted in summer directly for air conditioning. To verify this conception, an experimental system for storing natural cold energy in ground was first set up. The characteristics of using ground to store natural cold energy in winter were investigated. And the operating modes of the system were also discussed. During the whole cold storage, the cold capacity stored in ground was 16025.63 MJ and the energy efficiency ratio of 13.1 was gained. The temperature of the soil in the cold storage wells (boreholes) and around them decreased very evidently. These results show that in cold climates the conception of using ground to store the natural cold energy in the winter air is feasible.
