There is no pressure gauge in the process of adding fluorine to the air conditioner
Methods: fluoride 1. will be the first operation of air conditioning in the cooling mode, the fluoride mouth with Freon tank on one end of the tube with fluorine and fluoride, the other end tube (with fluoride thimble tube), installed in the low-voltage end of outdoor unit of air conditioner (suction tube) fluoride mouth. 2., open Freon tank plus fluorine valve on the mouth, can directly add fluorine to the air conditioning, fluorine amount of how much, should refer to the air conditioning nameplate marked "fluoride charge" for fluorine. Quantitative filling with scale. After the fluorine is finished, turn off the valve on the Freon tank and the fluorine nozzle, and let the air conditioner continue to operate. To observe the effect of air conditioning refrigeration, such as air conditioning to achieve normal cooling effect, low end remove outdoor machine (suction) plus fluoride mouth of fluoridation pipe, tighten the cap, and the mouth of the air conditioning fluoride can be used normally
Air conditioning adding fluorine step and method -- air conditioning adding fluorine concrete method operation:1. Turn on the air conditioner;When the fluorine is added in summer, the air conditioner can be directly operated in the refrigeration mode. Because of the heating system can not add fluorine operation, so in winter, when adding fluorine, you should use the method of making the valve line, forcing air conditioning into the refrigeration.2. Connect the fluoride equipment;After the normal starting of the air conditioner, the fluorine adding equipment is connected from the process port of the low pressure valve of the outdoor machine. In this procedure, air and dirt in the fluoride pipe must be removed.3 、 pressure plus fluorine;Low pressure observation in summer, the ambient temperature of about 32 degrees Celsius, the pressure control at around 0.45MP;In winter, high pressure is observed during heating, and the pressure is stabilized at about 1.7MP.4, removal of fluoride equipment;In the condition of removing fluorine refrigeration equipment, nano machine tighten external seal; if remove equipment under the heating state, will cause a lot of freon leak.5. Complete with fluoride.For suspected leakage of air conditioning, the use of detergent bubble examination.
