According to the investigation, in view of the current central air-conditioning market, there are some urgent problems to be solved in the production and use of air-source heat pump units and central air-conditioning. Research and development of ground-source heat pump units and ice-storing central air-conditioning systems will save energy and reduce user operating costs and the power grid. The peak adjustment has a very important significance and development prospects. Heat pump technology is an important technical measure to use low-level renewable energy, which can effectively reduce the speed of resource dissipation. It is also a model for the rational use of high-level energy, and it is of great significance for energy conservation and emission reduction.
In order to speed up the development and application of ground-source heat pumps, policies and enterprises need to work together. Industry experts recommend that the power sector should establish and improve preferential policies to encourage low-cutting electricity use as soon as possible, such as increasing the peak-to-valley electricity price ratio as much as possible, giving ice-storage air-conditioning equipment development and Use subsidies, etc. At the same time, it is also recommended that relevant manufacturers strengthen the research and development of ground-source heat pump units ice-storing central air-conditioning, lower the cost, improve the overall efficiency, and open up a broader market for house-type ice-storage central air-conditioning.
It is understood that with the emphasis of the “Twelfth Five-Year Plan†on low-carbon energy conservation, the use of groundwater source heat pumps and ice storage air-conditioning systems has become more widespread, under the premise of the “Twelfth Five-Year Plan†and the enhancement of people’s environmental awareness. In the coming years, new air-conditioning technologies such as ground source heat pumps will rapidly expand and develop.

If the land harness is normal,and the back reamer size reach 400mm,the one-gun-distance can be 150 meter but the operator need to pay high attention to the rig to see all the digital such as the rotation pressure and other.
If the back reamer size reach 500mm,600mm,the one-gun-distance can only be 90 meter.
Remark:One-gun-distance means the distance of drill bit go from one side and come out from the other size.Please see below explanation.
