Questions this course answers

What does a heat pump primarily do?

The refrigeration cycle transfers thermal energy using work.

What does the compressor add?

Compression raises vapor pressure and temperature while consuming electricity.

What does the reversing valve change?

It routes the cycle so indoor and outdoor heat exchangers exchange functions.

Why does frost reduce heating performance?

Ice impedes heat transfer at the source coil.

Why can COP exceed one?

Delivered heat includes energy collected from the source.
