PROBLEM TO BE SOLVED: To provide a heating and cooling system having an underground heat storage layer for storing plus heat quantity and minus heat quantity which stores minus or plus heat quantity on an underground part of a structural body such as a house and performs heating or cooling in the structural body by properly taking out the heat quantity.SOLUTION: An underground part of a housing H forms a plus heat storage layer 3A and a minus heat storage layer 3B. Hot water heated on a solar water heater 5 is supplied to the plus heat storage layer 3A and is heat-exchanged with heat storage medium in the plus heat storage layer 3A, and the plus heat quantity is stored. Similarly, cool water cooled on the solar water heater 5 in winter season or the like is supplied to the minus heat storage layer 3B and is heat-exchanged with the heat storage medium in the minus heat storage layer 3B, and the minus heat quantity is stored. The stored plus or minus heat quantity, for example upon the heating, is heat-exchanged with the plus heat quantity in an air duct D1 and hot wind is supplied indoors. On the contrary, upon the cooling, air in an air duct D2 is heat-exchanged with the minus heat quantity and cool wind is supplied indoors. |
