Abstract

The invention discloses a novel efficient cascade-use geothermal water heating method. The method comprises the following steps that: geothermal water serves as supplement of a heating pipe network; when a heat pump machine set does not run, circulating water of the heating pipe network sequentially flows through a user water divider and a user water collector so as to form circulation of the circulating water of the heating pipe network, meanwhile, in order to ensure the heat supplying temperature, part of circulating water in the user water collector is regulated through a valve and is recharged underground, and meanwhile, the geothermal water supplements the heating pipe network; when the heat pump machine set runs, the circulating water in the heating pipe network enters the heat pump machine set through the heat pump water collector, and enters a heat pump water divider after exchanging heat with the residual heat water sent by a low-temperature water tank, and then enters the user water divider and the user water collector sequentially so as to form circulation of the circulating water of the heating pipe network, meanwhile, in order to ensure the heat supplying temperature, part of circulating water in the user water collector is regulated, and is recharged underground, meanwhile, the geothermal water supplements the heating pipe network. The method not only utilizes renewable energy sources reasonably, but also can meet the heating requirement fully.
