如何查看空调是否缺氟?

来源: 日期:2020-05-15 发布人:admin
压缩机 连续运转30分钟后,若制冷系统“缺氟”,会出现下述现象:
After 30 minutes of continuous operation of the compressor, if the refrigeration system is "short of fluorine", the following phenomena will occur:
1、气管阀 门 发干,用手触摸没有明显的凉感。其原因是制冷剂不足导致 蒸发器 内的沸腾终结点提前,使该阀的制冷剂过度增大,阀门的温度升高,大于室外空气的漏点温度。
1. The air pipe valve is dry, and there is no obvious cool feeling when touching it by hand. The reason is that the lack of refrigerant causes the end point of boiling in the evaporator to advance, which makes the refrigerant of the valve increase excessively and the temperature of the valve increase, which is higher than the leakage point temperature of outdoor air.
2、液管阀门结霜。其原因是“缺氟”导致液管内压力下降,沸点降低,使阀门温度低于冰点。
2. The valve of liquid pipe is frosted. The reason is that the "lack of fluorine" causes the pressure in the liquid pipe to drop and the boiling point to drop, which makes the valve temperature lower than the freezing point.
3、打开室内机面板,取下过滤网,可发现部分蒸发器结露或结霜。其原因是由于制冷剂不足,仅仅使部分蒸发器发生了沸腾吸热,使制冷面积相应减少。
3. Open the indoor unit panel, remove the filter screen, and some evaporators can be found to be dewed or frosted. The reason is that due to the lack of refrigerant, only part of the evaporator has boiling heat absorption, which reduces the refrigeration area accordingly.
4、室外机排风没有热感。其原因是制冷剂不足导致冷凝压力、冷凝温度都降低,排风温度也随之降低。
4. There is no heat sense in the exhaust air of outdoor unit. The reason is that the lack of refrigerant leads to the decrease of condensation pressure and temperature, and the decrease of exhaust air temperature.

5、排水 软管 排水断断续续或根本不排水。其原因是蒸发器制冷面积减少,结露面积也减少,凝结水量降低。
5. The drain hose drains intermittently or does not drain at all. The reason is that the refrigeration area of the evaporator is reduced, the condensation area is also reduced, and the condensation water volume is reduced.
6、室外机气、液阀门有油污,有油污就有泄露。其原因是制冷剂与冷冻油有一定的互溶性,氟从漏点逸出后进入大气中,而油附着在漏点周围。
6. The air and liquid valves of outdoor unit have oil stain, and if there is oil stain, there will be leakage. The reason is that there is a certain degree of mutual solubility between refrigerant and refrigeration oil. Fluorine escapes from the leakage point and enters the atmosphere, while the oil adheres around the leakage point.
7、测量空调器的工作电流小于额定电流。其原因是制冷剂不足而使压缩机工负荷减少,电流下降。
7. Measure the working current of air conditioner is less than the rated current. The reason is that the lack of refrigerant reduces the working load and current of the compressor.
8、从室外机充氟口测量的压力低于0.45Mpa。其原因是制冷剂不足导致了蒸发压力下降。
8. The pressure measured from the fluorine filling port of the outdoor unit is lower than 0.45MPa. This is due to a decrease in evaporation pressure due to insufficient refrigerant.
另外,室外机任何一个阀门结霜都属不正常现象;只有液管阀门结霜说明“缺氟”;只有气管阀门结霜说明略微“缺氟”或环境温度过低;两个阀门都结霜说明系统有二次节流现象。
In addition, frosting of any valve of outdoor unit is abnormal; only frosting of liquid pipe valve indicates "lack of fluorine"; only frosting of air pipe valve indicates "lack of fluorine" slightly or low ambient temperature; frosting of both valves indicates secondary throttling of the system.
