What happens to the high temperature, high pressure refrigerant after it comes out of the compressor
of a heat pump (heating mode)?
A ) It evaporates in the coil, giving off heat to the inside
B ) It evaporates in the coil, absorbing heat from the inside
C ) It condenses in the coil, absorbing heat from the inside
,D ) It condenses in the coil, giving off heat to the inside - correct answer ✔✔D ) It condenses in the
coil, giving off heat to the inside
In heating mode, high temperature, high pressure refrigerant comes out of the compressor and
condenses, giving off heat to the inside
