Unpowered room temperature regulating device by using underground water

The utility model discloses an unpowered room temperature regulating device by using underground water. An underground blind shaft is built in a place with underground water at a hill higher than a building; the underground water automatically flowing out of the blind shaft flows to each floor of the building and the underground part by water pipes; a thermal insulation layer is coated on the water pipe from the blind shaft to the building; a water pipe is sleeved outside the thermal insulation layer; the water pipe is buried under 0.7 m below the ground; the water pipes in the floors are arrayed in a fence shape; air brought by the underground water flow enters rooms by the floors and the ground, and room temperature regulation is performed. The investment is little, the input of materials can be reduced as water pipes used for conveying drinking water can be shared, environment-friendly effect and noise-free effect are realized, and electric quantity and fuel cannot be consumed.
