Solution
A heat pump provides heat to a building by taking advantage of the physical process of "The absorption of heat when a liquid evaporates".
Here's a step-by-step explanation:
-
The heat pump uses a refrigerant, a special type of liquid that can absorb heat from the environment when it evaporates.
-
The refrigerant is circulated through the heat pump system. When it passes through the outdoor coil, it absorbs heat from the outside air, even when it's cold. This causes the refrigerant to evaporate and turn into a gas.
-
This gas is then compressed, which increases its temperature even more.
-
The hot gas then passes through the indoor coil. As it does so, it releases its heat into the building, providing warmth.
-
As it releases its heat, the refrigerant condenses back into a liquid and the cycle starts again.
So, the key process here is the absorption of heat when a liquid (the refrigerant) evaporates.
