Geothermal Energy systems Flashcards
It comes from the process of decay of ______________ element within the earth’s crust
geothermal energy, radioactive
_______________ is not truly a renewable resource
geothermal energy
One method used to extract thermal energy from the earth is called ____________
hydrothermal
___________________ ________ manifests in the form of hot springs, geysers, or through dry stream
Hydrothermal energy
Earth-coupled heat pump
geothermal heat pump
An electrically powered heat pump system that consists of pipes buried in the shallow ground newar the building, a heat pump, and ductwork in the building
geothermal heat pump systems
A fluid filled plastic pipes buried in the ground, or submerged in a body of water near the building
Ground loop
A device the remoces heat from the fluid in the pipes
Heat Pump
A type of heating/cooling device the draws heat into a building from outside of the building during the ________ season.
heat pump, heating
Conventional ductwork attached to the heat pump and used to distribute heated or cooled air throughout the building
Air delivery system
Geothermal heat pumps systems are calssified by the type of __________ that they use
ground loop
________________ geothermal heat pump systems circulate a solution of the water and antifreeze through a series of loops piping
Closed-loop
The _____ serves as a heat exchange medium between the ___ and the _______–
loops, fluid, earth
________________________ closed-loop system uses a number of horizontal _________
horizontal ground, trenches
_________________ designs range from a single pipe, to multiple pipes arranged vertically in a narrow trench, to multiple pipes in a wider trench
Piping system
___________________ closed loop system is used where there is little yard space, when surface rocks make digging impractical, or when you want to disrupt the lanscape as little as possible
Vertical ground
