In centrifugal compressors, low condensing pressure and large quantity of refrigerants.

High pressure and small displacement.

It is Low pressure large displacement.

I think it should be low pressure and low displacement because in my opinion, by displacement they mean the height or head up to which the refrigerant has to be raised.

It is a type of rotary compressor.

So in a rotary compressor, it gives low delivery pressure and high discharge rate. Whereas in reciprocating compressor it give high delivery pressure and low discharge rate.

So, the given answer is correct.
