Changing length of the evaporating coil
Dear members,
I am upgrading my existing cooling unit. Presently the unit has 750 BTU compressor, which I am increasing to 3600 BTU. The evaporating coil is presently of SS, 5/16" (8 mm) dia.
Coil length is 8 metres
Evaporating coil temperature is -7 degrees
The ambient temperature is around 40 degrees
The condensing temperature is around 55 degrees
Please suggest by how many times I have to increase the length of the evaporator coil to match the new compressor rating.
If any one can suggest the method to calculate the length of the evaporator coil based on these parameters, I would be highly obliged
Thanks and regards
Giridhar
PS: The present design is working perfectly.

Re: Changing length of the evaporating coil
I agree with Brian. Why not rather install a new system in parallel with the existing, perfectly-functioning system? Surely this is a lot less risky?

Re: Changing length of the evaporating coil
As per above...
You need to change the following:
Compressor
Condenser
Evaporator
Condenser fans
Evap fans
All piping
All valves
Distributor
Expansion valve
Liquid receiver
Suction accumulator

Re: Changing length of the evaporating coil
i also strongly recomend changing electrical cables so you dont overload the one you have

Re: Changing length of the evaporating coil
Hi there,
Everything said perfectly by others.
Increasing compressor power means increasing everything else like mentioned above.
I suggest you think again before making such changes.
