Willow Project Needs Chillers To Keep Permafrost Frozen
WebbComponents. Loop Thermosyphons consist of three main components, as describe below. Evaporator. Here heat enters the system, where it is transferred from the heat source into the working fluid, resulting in partial evaporation. Multi-micro channel evaporators are typically used. Tubing. Here fluid flow circulates between evaporator and condenser. WebbDuring operation the thermosyphon is insulated as the two other devices to avoid heat losses. Heat is provided by a cylindrical heater at the lower end of the devices and ranges between 20 W and 60 W. A cooling coil is wrapped around the upper end of the glass cylinder forming the condenser. rawhide pilot
Alaska Project Would Use ‘Chillers’ to Freeze Thawing Tundra (1)
WebbThermosyphons have been used for foundation stabilization in continuous and discontinuous permafrost areas since 1960 (Richardson 1979). As of January 2008, thermosyphons had been used in over 900 installations in AK alone (Figure 1) (Yarmak 2012).
