Geothermal technologies: environmental friendliness, efficiency and economy<\/h3>\n
Geothermal technologies are becoming a leader in the field of heating and cooling. They are a reliable solution for the efficient use of renewable energy. They provide heating, cooling of buildings and hot water supply, using the heat of the earth. The use of these systems reduces electricity costs and minimizes carbon dioxide emissions. For connections, the 90\u00d775 HDPE coupling is used.<\/p>\n
Advantages of geothermal technologies<\/h4>\n\n- Reliability and durability<\/strong>Geothermal systems operate year-round, regardless of weather conditions.<\/li>\n
- Environmental safety<\/strong>Heat pumps use the earth's heat, reducing dependence on fossil fuels.<\/li>\n
- Economic efficiency<\/strong>Significant savings are achieved on heating and cooling due to reduced operating costs.<\/li>\n<\/ol>\n
How does a geothermal heat pump work?<\/h4>\n
The geothermal heat pump uses electrical energy to convert the heat of the earth into usable energy for heating. The system is based on a geothermal circuit:<\/p>\n
\n- Horizontal circuit<\/strong>Pipes placed under the soil layer, requiring a large area.<\/li>\n
- Circuit vertical<\/strong>The pipes are lowered into deep wells, saving space.<\/li>\n<\/ul>\n
Regardless of the type of circuit, the heat exchanger transfers the accumulated heat to the circulating fluid in the system. The 90x32x8 geothermal water collector and 90\u00d775 HDPE coupling are used to connect all the wells into a single collector.<\/p>\n
System elements<\/h4>\n\n- Ground heat exchanger<\/strong>Made of HDPE pipes, it withstands pressures of up to 20 atmospheres.<\/li>\n
- Geothermal water collector 90x32x8<\/strong>. It joins the system circuits and connects to the heat pump.<\/li>\n
- Circulating fluid<\/strong>. Usually a mixture of ethylene glycol or propylene glycol with water.<\/li>\n
- Coupling 90\u00d775 HDPE<\/strong>Used for welding connections and flow regulation.<\/li>\n<\/ol>\n
Geothermal wells: installation features<\/h2>\n
The wells are placed in wells with depths between 70 and 300 meters. The main types:<\/p>\n
\n- Unicircuit<\/strong> (2\u00d732 mm sau 2\u00d740 mm).<\/li>\n
- Double-circuit<\/strong> (4\u00d732 mm).<\/li>\n<\/ul>\n
The temperature at a depth of 150 m is stable (~15 \u00b0C), which is sufficient for the efficient operation of the system. However, deep drilling requires significant investments.<\/p>\n
Installation and design<\/h4>\n\n- Carrying out geological analysis of the terrain.<\/li>\n
- Project development depending on soil type.<\/li>\n
- Compliance with safety regulations and environmental standards.<\/li>\n
- Using high-quality materials, such as HDPE pipes.<\/li>\n<\/ol>\n
