from it to derive your superheat. If your wine cellar is already at specified conditions (e.g.,
57 degrees F, 55% RH), and if your superheat is very low, or zero, you may have
overcharged your system.

准确的测量吸入管线的温度， 尽可能靠近压缩机入口端。同时，接上复合压力表，
在吸气检修阀门读取低端的吸入压力，（推回座阀门阀杆，使制冷剂从蒸发器不受
限制地回流到压缩机）。参照压力/温度图表，将吸气压力转换为的饱和温度。
由于吸气管的温度值高，从中减去饱和温度即可得到你的过热温度。如果你的酒窖
已经达到设定条件（例如，华氏度 57，55％相对湿度），如果过热度太低或接近零，
你的系统可能已经过多充注了制冷剂。
Sub-Cooling 过冷

With your compound pressure gauge set still installed with the high side connect to the
valve port on the liquid receiver (back seated valve stem to allow un-restricted refrigerant
flow from condenser to evaporator). Convert this liquid pressure to a saturated temperature
from pressure/temperature chart. Next, obtain your liquid line temperature by getting an
accurate reading on the liquid line BEFORE the TXV expansion on the indoor side. Obtain
this temperature entering the evaporator unit. Subtract the liquid line temperature from the
saturated liquid temperature to derive the system sub-cooling.

仍然将复合压力表接在高端液体接收阀门（推回座阀门阀杆，使制冷剂从冷凝器不
受限制地回流到蒸发器）参照压力/温度图表， 将液态压力转换为的饱和温度。接着，
在室内（内机）然膨胀阀前测量液体管线上的准确温度读数。查看进入蒸发器的确
切温度。从饱和液体温度中减去的液体管线温度，得出系统的过冷温度。
When comparing your high side system pressure to supplied charts below, refer to the liquid line
pressure.
如果比较的高端系统压力，请参照以下图表， 指液体管线压力。
To give you an idea on how much R134A refrigerant charge you may require to reach full
charge for your given interconnecting line length, see the very general guidelines below based
on liquid line size:
使用 R134A 制冷剂充足整个系统， 以下图表是一般互连管线直径大小的参照表。
WGS40, WGS75 63mm OD ~ ..45g/m
WGS100, WGS175 1cm OD ~ .90 g/m
**Based on factory testing using 8cm of interconnected piping 基于出厂前测试，使用 8m
英尺连接管道。
WG40 = 35 ounce total charge
WG75 = 39 ounce total charge
WG100 = 60 ounce total charge
WG175 = 73 ounce total charge
