Ground probe<\/strong> \u2014 is an element of a geothermal heating system, which is a vertical or horizontal pipe immersed in the ground to a certain depth. The main function of a ground probe is to heat collection<\/a> from the ground and transferring it to the coolant, which circulates inside the probe.<\/p>\n

Ground probe: application features<\/h3>\n

Ground probes are typically used in conjunction with heat pumps to heat and cool buildings, providing a stable and efficient source of energy because the temperature of the ground at a certain depth remains relatively constant year-round.<\/p>\n

Ground probe<\/strong> and heat pump<\/strong> form the main part of a geothermal heating system. In this system, the ground probe acts as a heat exchanger, which takes heat from the ground and transfers it to the coolant circulating through the system.<\/p>\n

Equipment set:<\/h3>\n
    \n
  1. Ground probe<\/strong>:\n
      \n
    • Vertical probes<\/strong>: Installed in deep wells (up to 100-200 meters). This type of installation requires drilling and is used when the area of the site is limited.<\/li>\n
    • Horizontal probes<\/strong>: They are laid at a shallow depth (1.5-2 meters) and require a larger land area for placement. They are usually mounted in the form of spirals or serpentines.<\/li>\n
    • Materials<\/strong>: Probes are made of polymer pipes (e.g. high-density polyethylene) that are resistant to corrosion and chemicals.<\/li>\n<\/ul>\n<\/li>\n
    • Heat pump<\/strong>:\n
        \n
      • Compressor<\/strong>: The heart of the heat pump, which compresses the coolant (for example, freon), increasing its temperature.<\/li>\n
      • Evaporator<\/strong>: Here the coolant absorbs the heat coming from the ground probe.<\/li>\n
      • Capacitor<\/strong>: Transfers the collected heat to the heating or hot water supply system.<\/li>\n
      • Circulation pump<\/strong>: Ensures the movement of the coolant between the ground probe and the heat pump.<\/li>\n
      • Expansion tank<\/strong>: Stabilizes the pressure in the system.<\/li>\n<\/ul>\n<\/li>\n<\/ol>\n

        System operation:<\/h3>\n
          \n
        1. Heat absorption<\/strong>: A heat carrier circulates in the ground probe, which takes heat from the ground. The temperature of the ground at a certain depth remains stable all year round (about 10-15\u00b0C).<\/li>\n
        2. Heat exchange<\/strong>: The heated coolant enters the evaporator of the heat pump. In the evaporator, it transfers heat to the refrigerant, which evaporates.<\/li>\n
        3. Compression<\/strong>: The refrigerant in its gaseous state is compressed by the compressor, which significantly increases its temperature.<\/li>\n
        4. Heat dissipation<\/strong>: The heated refrigerant enters the condenser, where it gives off heat to the heating or hot water supply system.<\/li>\n
        5. The cycle repeats itself<\/strong>: The refrigerant, having given up its heat, enters the evaporator again, and the process is repeated.<\/li>\n<\/ol>\n

          Advantages:<\/h3>\n
            \n
          • High efficiency<\/strong>: The ground provides a stable heat source, allowing the heat pump to operate with a high coefficient of performance (COP).<\/li>\n
          • Environmental friendliness<\/strong>: Using renewable energy reduces CO\u2082 emissions.<\/li>\n
          • Autonomy<\/strong>: The system requires virtually no external energy sources, except for power supply to operate the pumps and compressor.<\/li>\n<\/ul>\n

            Ground probe<\/strong> and heat pump<\/strong> represent an environmentally friendly and cost-effective heating solution, especially in regions with cold winters where traditional heating methods may be less efficient.<\/p>","protected":false},"excerpt":{"rendered":"
