"Our community take a geothermal heating, during the winter just stay, home to rehu; last year, the temperature still appropriate; this year was no rehu gas ..." a few days ago, the family lived in the South of Ms. Li reflected to this newspaper. At the same time, there are some house adapted a geothermal heating of users have also been reflected in the low temperature.
Compared with conventional heating methods, geothermal heating has many advantages, but what kind of building the most suitable for geothermal heating? how to use and maintenance of geothermal? the heating sector related technical personnel to answer.
The initial heating to progressive
Geothermal energy is the heat from the ground up in the form of heating. Geothermal first starts, the first half open water separator water total loop valves, let the water temperature rises gradually into the pipeline in the loop. At the same time check the water separator the interface is abnormal, and one by one open water separator each branch valve. The first heating time, also check heating pipelines and valves, valve is opened, the water Division of upper and lower temperature piping is there, and checked for return pipe temperature and temperature difference. In General, water supply pipe temperature should be higher than the return water temperature 10 ° c to 15 ° c.
Pipeline cleaning can't ignore
So, why geothermal heating effect than a year?
According to reports, geothermal tube scaling will seriously affect the heating temperature, so irrigation geothermal pipeline best regularly, there are three main methods: water cleaning, washing, chemical use geothermal pipeline cleaning machine cleaning. Finally a simple, fast method to compare the most thorough cleaning effect.
Technical personnel to remind that each water separator before are equipped with a filter, when too many impurities in the water, the filter should be cleaned up. Filter impurities excessive, geothermal heat not, therefore, every other year would be cleaning filter.
Cleaning, turn off the water separator on all valves with adjustable wrench open end cap counterclockwise filter, remove the filter for cleaning, cleaning is installed after. Then open the valve, geothermal system is working properly. If the winter is not heating indoor temperature is below 0 ° c, the user should also be geothermal water drain pipes to prevent Frost crack pipe.
Central heating to geothermal caution
Since installing geothermal belonging to implicit and does not affect beauty, space, more and more families want traditional heating into geothermal.
To this end, the heating sector, geothermal heating system does not apply to all buildings, the current installation, adaptation has wide blindness and follow the trend.
Today, the main form of the geothermal heating system has two types of geothermal heating, soon-to-metal tube, pipe, etc. into concrete floor in coal, oil, gas boilers or electric boiler to provide hot water heating, electric geothermal heating, heating cable buried in concrete floors, rely on electricity for heating or heating. Plumbing geothermal differential pressure of the pipeline network has its own unique requirements, if unauthorized modification, it is easy to cause the user to use other radiator heating not hot.
In addition, some install geothermal heating business professional technology is not perfect, it is difficult to ensure that the water pipe butt out, once the leak, the consequences would be unthinkable. If you really want to change, must be guided by the relevant personnel.
