Heat Pump Modification

[mallmk13]

i finished my first year NVQ 2 COLLEGE IS CLOSE NOW WE HAVE BEEN THOUGH THAT CONDENSERS ARE BIGGER THAT EVAPORATOR IF IT IS THE CASE.

1/ WHAT IS THE PHENOMENON OF HEAT PUMP SYSTEMS WHERE BOTH COILS ARE EQUALE?

2/ASSUME I MODIFY THE HEAT PUMP BY ADDING A AN EVAPORATOR BOX AND LIQUID RECEIVER WILL IT WORK AS HEAT PUMP AND COOL ROOM?

PS: ALL CALCULATION MUST BE TAKEN IN CONSIDERATION.

Hi, no need to SHOUT

1) Who says that they are the same size ?

2) Don't understand the question, heat pumps will normally work in both directions as standard.

Evaporator extracts heat at a DT of 6 to 10 K and the condensors rejects this heat and the absorbed compressor power back with a DT of 15K back to the outside.
So the 15K is at least twice or 1.5 bigger then the 6K, so the condensor can be half the size of the evaporator .
Most condensors have a fin spacing half of that of the evaporator, so again a reason why the condensor is smaller.
And your instructors told you that condensors in general are bigger????
