földszivattyúsgeotermikus

földszivattyús is a Hungarian term that translates to "ground pump" or "earth pump." It refers to a type of pump system that utilizes the stable temperature of the earth as a heat source or sink. These systems are commonly employed in geothermal heating and cooling applications. The core principle involves circulating a fluid, typically water or a water-antifreeze mixture, through a buried network of pipes. In winter, the fluid absorbs heat from the ground, which is relatively warmer than the ambient air, and transfers it to the building. In summer, the process is reversed; the fluid absorbs heat from the building and dissipates it into the cooler earth.

The buried pipes can be configured in various ways, including horizontal loops, vertical boreholes, or pond/lake loops, depending on the available land area and geological conditions. The efficiency of a földszivattyús system is influenced by factors such as the depth and length of the piping, soil type, moisture content, and the temperature difference between the ground and the building. These systems are known for their energy efficiency and environmental benefits, as they reduce reliance on fossil fuels and lower greenhouse gas emissions. Maintenance typically involves periodic checks of the circulation pump and fluid levels.
