摘要

相信冷凍空調從業者或者是學生的您，是否常聽老師傅或是老師提過氣冷式的高壓壓力比水冷式的高、R-410A系統的高壓壓力較R-22的高約六成左右以及R-134a空調系統為正壓系統而R-123則為負壓系統等等問題所困惑呢？乍看之下，好像不成問題；但是仔細推敲好像似懂非懂，無法精確的回答。本文就基於此現象，以輕鬆的心情將硬邦邦的原理以口語化淺顯易懂的方式，套到實務上空調系統及冷凍循環系統四大主要元件存在必要性中，讓大家從中體會實務並精確的說出答案。

Have you ever been confused by problems in the practice of HVAC&R, such as the condenser pressure in the air-cooled system is always higher than that of a water-cooled one, the condenser pressure in the R-410A water-cooled system is about 60% higher than that of the R-22 system, and the R-134a system is a positive pressure system, while the R-123 is a vacuum pressure one. In this article, you will get the picture of the system, from the alternative statement without theoretical discussion.
