Different manufacturers are different, the length of the pipeline is different, about 1000-1500 grams.
The pressure is 0.35~0.55Mpa, if it is high, it is more, if it is low, it is less. The high pressure should not exceed 2.2Mpa (if the sound is too large and dull, it may also be added too much fluorine, if the sound is too small, it means that the amount is not enough).
The air conditioner opens and cools from the low pressure, when it is added to 0.35~0.55Mpa, then observe the cooling effect of the air conditioner, if possible, the high pressure can not exceed 2.2Mpa
The refrigerant of a large 1.5 HP air conditioner is generally between 500 and 800 grams.
However, it is recommended that you check the nameplate of the outdoor unit. What you need to pay attention to is not only the amount of refrigerant charged, but also the model of refrigerant. Don't get the model wrong.
Now most of the household air conditioners are using R410A, R32 refrigerant.
The old fixed-frequency air conditioners may use R22 refrigerant.
When the 1.5p air conditioner is fluoridated, it generally does not exceed 1 kg. If you look at the pressure gauge, the pressure between 0.45 and 0.6 kg is normal, and some brands even exceed this number mainly according to the ambient temperature, 0.45 kg is almost 24 degrees or so, if the weight of each air conditioner will indicate the weight and rated current of the air conditioner. The average 1.5P snow seed weighs between 0.6 and 0.9 kg.
