空調各溫度執行壓力對照表

室內溫度設定27度，啟動壓縮機運轉，運轉中的壓力約如下：

1、如果是R410A製冷劑的空調機運轉時，低壓壓力約在0.8MPa左右、高壓壓力約在2.2~2.4MPa左右

2、如果是R22製冷劑的空調機運轉時，低壓壓力約在0.5MPa左右、高壓壓力約在1.3~1.5MPa左右

其中：1個MPa約等於10kgf/cm^2。

變頻空調是指其壓縮機的工作電源的頻率是可變的，壓縮機的轉速也可變的空調。變頻空調依靠壓縮機轉速的變化而不是停機來達到控制室溫，因此室溫波動小、電能消耗少而且它能使舒適度大大提高，具有節能的優點。

空調各溫度執行壓力對照表

1、可以看到錶盤上面有兩行圓形數字，分為紅色和藍色的，外加一個指標。

2、紅色的是高壓度數，藍色是低壓度數。一般所說的數字都是低壓。

3、 任何使用氟利昂22的空調在製冷狀態下執行時，環境溫度在25度到45度時的壓力都應該是0.45-----0.6MPa。

4、R22的溫度看紅色最內圈，R22的壓力對應值看最外圈黑色的值(35kg/cm²=3.5MPa 是10倍的關係)。

5、紅圈和藍圈共四種介質是在同一種壓力下對應的不同介質的溫度。

6、表上的刻度是壓力，通過壓力顯示可以知道壓縮機的排氣壓力(高壓)和進氣壓力。
