Technical question

[chichi]

Dear friends,

i have a question,
i know if condensing temperature to be lower,COP to be higher(power consumption is lower and refrigeration capacity is higher),but when i select a screw compressor with condensing temperature Tc=38,suplier offerd me a range of condensing temperature 32<Tc<48 .why we can't work with Tc=25C or less
