PROBLEM TO BE SOLVED: To facilitate manufacture with a simple structure, to save energy, to facilitate installation, to reduce cost, and to reduce direct and indirect air pollution caused by a conventional air-conditioning system, a high cost situation of an electric power using type air conditioning system and various kinds of natural environmental destruction by a combustion type heating system. SOLUTION: This heating-cooling air conditioner is composed of a concrete mass 1 embedded in the ground, and an air circulation pipe 2 incorporated in the concrete mass 1. The air circulation pipe 2 is formed in a straight pipe-like shape in the horizontal direction, and a plurality of heat transfer pipes 3 each formed by filling an aluminum pipe with mortar concrete are radially arranged in the radial direction of the air circulation pipe 2 by making them pierce therethrough. The air circulation pipe 2 is provided with an air supply opening 5 and an air blasting opening 6. The heating-cooling air conditioner is buried in the ground by setting the underground depth at least not smaller than 3 m and preferably not smaller than 5 m. COPYRIGHT: (C)2007,JPO&INPIT
