Determining the amount of charge – When “refrigerant side” head pressure control is
utilized on a system, one of the most important factors is determining the total system
refrigerant charge. While on most packaged units the amount of charge is listed on the unit,
the required charge for a field built-up system cannot be listed by the manufacturer. Charge is
usually added when the system is started up until “proper” system performance is reached.
However, this is not satisfactory and if the system is to function properly year-round, the
correct amount of extra charge must be calculated ahead of time.
当设备使用“制冷剂侧的”头压力控制，其中最重要的因素之一是确定整个系统所需的
制冷剂 量 。大多数的封闭式系统其制冷剂量一般已列在设备铭牌上，但分体机需要现
场冲剂，制造商很少列出制冷剂量。当系统启动时，现场注入制冷剂量，直到系统性能
达到“恰当的”为止。然而，这是不令人满意的解决方法。如果系统需要全年正常运行，
额外补充的制冷剂量必须提前正确地计算出来。
Procedures for Charging System with Head Pressure Control 使用头
压控制的冲剂程序
WGS40, WGS75, WGS100,WGS175)
NOTE: When charging any system with head pressure control the outdoor
ambient temperature must be known.
注意：使用头压控制，系统冲剂前，室外环境
温度必须知道。
Charging of Systems with Head Pressure Control in ambient above 20 degrees C (After
normal evacuation procedures):
温度高于 20c 华氏度，系统冲剂使用头压控制（正常放气手续后）：
1. Connect refrigerant cylinder to a charging or gauge port on the receiver outlet valve.
2. Open the receiver valve approximately one-half way (so receiver and liquid line are
connected to charging or gauge port).
3. Charge liquid refrigerant into the high side of the system. Weighing the charge is
recommended.
4. Remove the refrigerant drum and connect it to the suction side of the compressor.
5. Charge refrigerant vapor into the low side. Do not allow liquid refrigerant into the low
side.
6. Start the system.
7. Observe sight glass (at receiver outlet) to see if system is filling with refrigerant for
normal refrigeration cycle.
1。 制冷剂罐连接到接收器出口阀门。
2。打开接收器阀门大约一半的地方 （接收器连接到液体管线仪表端口）。
3。充液态制冷剂进入系统的高端。建议称量制冷剂的重量。
4。除去制冷剂鼓，并将其连接至所述压缩机的吸入侧。
5。注充
气态制冷剂 进入低端。千万不要让液态制冷剂进入低端。
6。启动机器。
7。观察视瓶（接收器端口），在正常的制冷循环下，看看制冷剂是否注入系统。
