First of all, the most attractive aspect of geothermal pump heating is its high efficiency. This means that electricity consumption can be saved, effectively reducing electricity bills.
Geothermal heat pump technology has continued to develop since geothermal energy began to be used in the United States in the 1940s. Compared to using air conditioners for heating or cooling, geothermal heat pumps are obviously much more efficient, reliable and durable. The lifespan of a geothermal heat pump can range from 25 to 50 years.
In addition to high efficiency and long-term use, geothermal pumps also have the advantages of low noise and low maintenance costs. No matter how you look at it, it's a good deal. In Oklahoma, a house with an area of approximately 280 square meters can accommodatemeet all energy needs for only $60 per month with a geothermal pump.
However, since the use of geothermal pumps requires consideration of many factors, including some uncertain factors such as local geological conditions, the promotion of geothermal pumps still faces many challenges. obstacles. Geothermal power plant, but the overall pace of development of geothermal use is still relatively slow and fraught with difficulties. Because if you want to build large-scale electricity production facilities, you have to dig deep into the ground. Often a project requires tens of thousands of dollars for preliminary exploration. On average, dozens of diamond drill bits are needed for every kilometer drilled underground, and each drill bit costs at least $2,000. However, it is possible that sufficient reserves will not be discovered afters very deep drilling. There is therefore a price to pay for developing underground thermal energy. In addition, the cost of installing a geothermal heat pump is difficult to estimate. Due to different geographical conditions in different locations, it is difficult to calculate a representative cost of using geothermal pumps.
The role of security protection.
Since the ground wire made by us serves as a safety protection, it can only protect electrical appliances within five meters of it. Therefore, within this range, the ground wire made by us. Only one electrical device can be connected.
When a generator with static excitation and rotor grounding protection operates normally, there is a certain insulation resistance and capacitance distributed between the excitation circuit and ground when the insulation of the windingexcitation is seriously reduced or damaged. , this will cause the excitation circuit to fail.
