I don’t understand why propylene refrigeration compressors, which are used specifically for cooling, do not have inter-stage coolers Please, experts, give me some advice

There’s one thing I don’t understand: many compressors are equipped with inter-stage coolers. Then why don’t propylene refrigeration compressors, which are used specifically for cooling, have such coolers? Wouldn’t that result in increasing temperatures downstream and higher energy consumption? Why is that? Please ask the experts for guidance
Since propylene has a relatively low boiling point, the presence of an inter-stage cooler can lead to liquid accumulation, which affects the air intake of the compressor. It is not conducive to the operation of the compressor
Can a low boiling point also cause fluid accumulation? Besides, the liquid accumulation can be resolved using a condensate recovery tank
Why is inter-stage cooling necessary, and where should the cooler be installed? It is almost in a saturated state upon vaporization in the kettle-type heat exchanger; is it necessary to condense it into a liquid phase using a cooler?
