What is the difference between the vertical buried pipes and the double U pipes?
Buried pipe U-head
First of all, let's briefly talk about what is a single U pipe, what is a double U pipe, a single U pipe is to go down two pipes in a well, the bottom is a single-way circulation U-shaped connector, double U is to go down to four pipes in the well, and at the bottom of the pipe is a double-loop U-shaped connector.
Single U tube
The general depth of the vertical buried pipe is 80-120 meters, and it is found through a large number of thermal response data reports that the heat exchange of the single U-shaped buried pipe is generally 40-60w/m, and the heat exchange of the double U-shaped buried pipe is about 1.2 times higher than that of the single U-shaped buried pipe under the same conditions, but the material cost of the PE pipe will increase exponentially.
Double U tube
The choice of single U and double U should be based on the site situation, if the drilling site is limited or the geology is rock when the cost of drilling is relatively high, the number of wells should be minimized to choose double U buried pipe.
