Ground source heat pump consists of two, one level underground, one for vertical borehole; specification: horizontal connecting pipe depth should the permafrost below 0.6m, and from the ground should not be less than 1.5m. Horizontally pipe commonly used in single-phase operation of the air conditioning system in the state, the general design of borehole depth of between 2 to 4 m, in only used for heating, the heat in the soil throughout the winter state, a certain depth of the groove deeper, larger tube pitch. Vertical ground heat exchanger pipe should be greater than the depth of 20m, drilling aperture of not less than 0.11m, drilling spacing should be required to meet the heat exchanger, the spacing should be for 3 ~ 6m. Vertical borehole heat exchangers are usually U-shaped manner, according to the depth of pipe can be divided into shallow (<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 a corresponding drilling, drilling equipment and funding high pressure pipe cost increase. Anqiu Yuquan is an efficient and well-drilling machinery; pragmatic; services in one of the professional teams, Yuquan mechanical drilling team has eight sets of DTH drilling wells drilled Professional undertaking various projects, as well as ground source heat pump drilling project. The company mainly produces: well drilling rig, core sampling rig, material and other special geological drilling equipment. Please call us, our service is your satisfaction!
