I Have compressor which capacity 46.2 Kw , I need decrease the capacity to 42.6 Kw to matching with evaporator which capacity 42.6 Kw . What can I do ??

You dont need to do anything.
Your compressor is capaity is 8% more.
Its fine.

capacity will decrease as evaporating temp. will drop.

As c-c says, it could probably be left well alone.

If you are concerned about matching & balancing, then you could look into installing a service valve in the suction line between evap & compressor. Set the valve during first operation, if required, then leave it alone after that.

Trimming of the evap can also be performed by backing off on the evap fan speed.
