Abstract (en)
[origin: WO2008039202A1] An encasement assembly (1) for installing sub-surface refrigerant tubing in a direct exchange heating/cooling system includes a weighted and protective encasement tube (2) for lowering the bottom distal U-bend portion (8) of the refrigerant tubing into a well/borehole (21). The encasement tube (2) has a main body portion and a rounded or cone-shaped nose. The U-bend portion of the distal end of the refrigerant transport lines (5, 6) is encased within a cementitious grout (15) inside the tube (2). The grout (15) inside the encasement tube (2) has a flat top portion to prevent upward flotation and at least one eyebolt (11) for securing a trimmie tube (14) with an expendable wire (19) during installation. An optional nose ring (34) is attached to the lower distal end of the tube (2) for marker float (39) attachment in water.
