4.1. High-Efficiency Heat Pumps

Try these first

1. 1.

   What is one type of high-efficiency heat pump?

   Hint

   Think about what uses ground temperature.

2. 2.

   What does a heat pump do?

   Hint

   Consider heating in winter and cooling in summer.

3. 3.

   What is the primary function of a high-efficiency heat pump?

   • A) Cool air only
   • B) Transfer heat for heating and cooling
   • C) Heat water only

   Hint

   Think about both winter and summer uses.

4. 4.

   High-efficiency heat pumps can achieve efficiency ratings of what percentage?

   • True
   • False

   Hint

   Consider the energy produced relative to energy consumed.

5. 5.

   Calculate the energy savings when a traditional HVAC system uses 100 units of energy versus a high-efficiency heat pump using 25 units to achieve similar operational output.

   Hint

   Consider the energy input against the output.

6. 6.

   Critically assess the impact of high-efficiency heat pumps in urban environments concerning energy independence and climate change mitigation.

   Hint

   Think about environmental benefits and transformation in energy landscapes.
