Classification of geothermal heat pump or water source heat pumps.
Answer to Problem 1RQ
Open loop and closed loop.
Explanation of Solution
Geothermal heat pumps are generally classified into open loop and closed loop systems:
Open loop systems, also known as water source systems utilize the water from the earth as a heat transfer medium and extract back the water back to the earth.
However, closed loop system, also known as earth-coupled systems. In such systems, plastic pipes are buried within earth, lakes or ponds, and a heat transfer fluid is circulated through the pipes.

- Differentiate refrigerator and heat pump.arrow_forwardDEFINE THE REFRIGERATORS AND HEAT PUMPSarrow_forwardRefrigerators and air conditioning systems perform the same function of maintaining cool or cold conditions in an environment. However, refrigerators are place inside while air conditioners are usually placed outside because Question 13 options: refrigerators function better when in a small enclosed space. air conditioners need to release heat to the outside. air conditioners need to use air from the outside to function. refrigerators need to be placed in an environment of constant temperature and pressure.arrow_forward
