Ground source heat pump is divided into two, one level underground, one for the vertical pipe; specification: horizontal connecting pipe depth should be at the permafrost below 0.6m, and from the ground should not be less than 1.5m. Horizontally pipe commonly used in air conditioning systems running single-phase state, the general design of borehole depth of between 2 and 4 meters, used for heating in only when the soil throughout the winter in the heat state, a certain depth of the groove deeper, larger tube pitch. Vertical ground heat exchanger pipe depth should be greater than 20m, drilling aperture should not be less than 0.11m, borehole spacing should meet the needs of the heat exchanger, the spacing should be for 3 ~ 6m. Vertical borehole heat exchanger is usually U-shaped manner, according to the depth can be divided into shallow borehole (<30 m), middle (30 ~ 100 m) and deep (> 100 m) 3 species. Buried deep underground rock temperature is relatively stable, less drilling footprint, but will bring the appropriate drilling, drilling equipment and the provision of high pressure pipe cost increase. Anqiu Yuquan mechanical drilling crew is an efficient; pragmatic; services in one professional team, Yuquan mechanical drilling team has eight sets of DTH drilling wells drilled professionals to undertake all types of projects, as well as ground source heat pump drilling project. The company mainly produces: well drilling rig, core sampling rig, geological and other special things rig equipment. For more details, please call us, our services, is your satisfaction!
