The well is encased and sealed at its bottom to prevent the loss of water. The casing of the well is in contact with the surrounding earth for heat conduction. A pipe is placed within the well with a pump at its distal end. The pump draws cold water from within the well into the pipe, out of the well into a heat exchanger where it cools the air which, in turn, cools the house. After the water has gone through the heat exchanger, it is returned to the well. Heat pipes are used to dissipate, in winter, the heat accumulated during the summer cooling months. The heat pipes extend outwardly from near the top of the well and contain a substance that will absorb heat and evaporate at the end in the well and condense and release heat at the opposite end. An upward slant of the heat pipe ensures that this heat transfer occurs only in the direction away from the well. | |
