制冷系统经过检漏,干燥抽空后,就可以充灌制冷剂了。为减少不凝气体和水分进入制冷系统,充灌制冷剂应使用液态。在钢瓶内液态制冷剂不多的情况下,可把钢瓶底部垫高使阀门处于最低位置,这样充灌的制冷剂都是液态。夏天,由于气候炎热,可用冰块堆在钢瓶周围,供气瓶内液体增多。如果制冷剂所含水分较多,应安裝干燥过三器,对制冷剂进行干燥过滤,以避免水分进入制冷 After the leak detection of the refrigeration system, the dryer can evacuate the refrigerant after it is emptied. To reduce the non-condensable gases and moisture into the refrigeration system, the refrigerant should be filled with liquid. In the cylinder of liquid refrigerant in the case of small, the bottom of the cylinder can be lifted so that the valve in the lowest position, so filling the refrigerant is liquid. In summer, due to the hot weather, ice cubes can be piled around the cylinders to increase the liquid in the gas cylinders. If the refrigerant contains more water, should be installed over three dry, the refrigerant dry filter to prevent moisture into the cooling
