5。如果系统的工作环境温度比冲剂时环境温度要低，额外的制冷剂则需要现在添加。
Since good system performance during low ambient operation depends on proper refrigerant
charge, it is very important that this phase of the installation procedure be done carefully.
Many times, poor system performance will be due to too little or too much charge. And in
many cases, this will be the last item suspected.
在低温环境中，系统性能运行良好的因素取决于制冷剂的正确充注，这是非常重要的，
安装过程的这一阶段应该谨慎进行。很多时候，系统性能不佳就是由于注剂过少或注剂
过多造成。在许多情况下，此步骤是值得疑问的最后一步。
With the system started 系统启动后

After following instructions on the previous page on initial Charging for Systems with
Head Pressure Control, with refrigerant tank now connected to suction line (low side) port
to add remaining charge in a gas state, refer to the provided charts for proper system
operating points as equated to ambient temperature with wine cellar at normal conditions of
14 degrees C / 55%RH. Refer to Split Systems Operations chart on page 60 for system
pressures, sub-cooling, and superheat values to allow you to charge your system correctly.

安照使用头压控制的冲剂程序初始冲剂后，制冷剂罐 连接到吸入管（低端）端口添
加剩余的气 态制冷剂，请参阅提供的图表对于系统 为酒窖正常工作所需的 57 华氏
环境温度和 55％RH 相对湿度提出的要求。 并请参阅分体式系统操作图 39 页上的系
统压力表，过冷，过热的指数，给你的系统冲注正确的制冷剂量。

In addition to using the charts provided, there is a liquid line moisture/sight glass located in
the condensing (outdoor) unit that will assist you in knowing that you have sufficiently
charge your system, HOWEVER a full sight glass or a glass with bubbles does not
necessarily mean you are properly charged, or undercharged. There may be other factors
affecting sight glass, so do not charge by sight glass method only. A full sight glass-
matched with proper system pressures, sub-cooling, and superheat values is the proper
method for confirming that the system charge is correct for your application.

除了使用提供的图表，液体管线的湿度/视瓶 （位于冷凝器 “外机”机组），这有助
知道系统中的制冷剂量，但是，视瓶已满或视瓶 有气泡并不一定意味着冲剂正确，
或冲剂不够。有许多因素可能影响视瓶的结果，所以不要只依靠视瓶进行充剂。满
视瓶加上适当的系统压力，过冷，过热数值适当应该是制冷剂冲注的正确方法。


Get an accurate suction line temperature on the suction line as close to the compressor inlet
as possible. At same time, attach a compound pressure gauge set to the system so as to read
the low side suction pressure at the suction service valve port (back seated valve stem to
allow un-restricted refrigerant flow from evaporator back to the compressor). Convert
suction pressure to a saturated temperature as derived from a pressure/temperature chart.
Since the suction line temperature is the higher value, subtract the saturated temperature
