liquid cooling

[GENERALCOOL]

Hi friends,

We have a cooling system and want to decrease liquid temp. from 90C to 5C.
I know for this type of cooling we should use 2 stages. First decrease temp. via cooling tower to about 40C and then decrease form about 40C to 5C via compressor on evaporator.
Now suppose we need omit cooling tower and want to decrease form 90C to 5C in one stage with compressor.
As you know refrigerant temp. coming back to crankcase and compressor should not be more than about 25C ~ 30C.
But in first hours our liquid at evaporator is 90C and returned refrigerant to compressor is very warm.

By injecting liquid to crankcase can we solve this problem ?
