1. 作用原理與離心式製冷機的技術細節

Centrifugal chillers employ centrifugal compressors to drive the refrigeration cycle. Their primary advantages arestor kraft kølekapacitet, høj effektivitet og lavt støjniveau.

1.1 Çalışma Prensibi

De centrifugaalcompressor is het hart van de centrifugaalmachine. Deze comprimeert het koelmiddelgas met hoge snelheid, waardoor een damp met een hoge druk en temperatuur ontstaat. Deze damp stroomt vervolgens naar de condensor, waar deze wordt afgekoeld tot een vloeistof. Het vloeibare koelmiddel stroomt via het expansieventiel naar de verdamper, waar het warmte onttrekt aan het proces of de omgeving, waarmee de koelcyclus wordt voltooid.
