Open loop systems are also known as this type of system.
What is a water source.
100
This loop is flattened, circular coil of pipe, and can reduce the trench lengths by 1/3 to 2/3 compared with other system loops.
What is a slinky loop.
100
Polyethylene and Polybutylene are joined together using this process.
What is heating, melting, ect.
100
This system eliminate water quality problems.
What is closed loop system.
200
Closed loop systems can also be referred to as these two terms.
What is ground and water loop.
200
In an open loop system if the minerals in the heat exchanger restrict the heat transfer it will cause the head pressures to do this in the cooling mode and the suction pressure to do this in the heating mode.
What is head pressures would be high in cooling mode and low suction pressures in the heating mode
200
These four paths are used in a ground loop systems.
What is series vertical, parallel vertical,series horizontal, parallel horizontal.
200
This type of additive to the loop system has a tendency to turn into a gel at low temps.
What is Glycol.
200
Geothermal heat pumps are are classified as these two types of systems.
What is open and closed loop.. :0

This antifreeze material can be corrosive when in contact with metals and mixed with air.
What is salts.
300
Waterless geothermal heat pumps utilize this instead of buried water lines.
What is buried refrigerant lines.
400
Closed loop systems are generally used in these areas..
Where there is insufficient water quality or quantity or where local codes prohibit open loop systems.
400
Open loop systems USUALLY use this type of water as their heat source and heat sink.
What is well water.
400
Two advantages of a parallel-flow systems are these..
What is -Smaller diameter=low cost; -lower installation and labor costs; -Less antifreeze required.

The buried piping or heat x-changer are made up of these materials...
What is Polyethylene or Polybutylene.
500
These solenoid valves are almost always positioned positioned in this line to keep the co-ax heat exchanger at the same pressure as the pressure tank in the off cycle.
