1.5 household air conditioning general how many kilograms of refrigerants
Different manufacturers, different pipe length, about 1000-1500 grams, general complement main lateral pressure. Measure the pressure at the low pressure is 0.35 ~ 0.55 Mpa. If on the high side, then add much, if low, add less. High pressure can't more than 2.2 Mpa (listen to the voice, if the sound is too big, depressing, may also be added fluoride, if the sound is too small, not enough). Using low pressure filling and static injectors. 1. Air-conditioning refrigeration and then from the low pressure with tears, when added to 0.35 ~ 0.55 Mpa can, again observe air conditioning refrigeration effect. If you can, high pressure measurement cannot be more than 2.2 Mpa. 2. When the air conditioning stopped, from add fluoride and fluorine. When the system pressure is 0.8 ~ 0.8 Mpa is more appropriate. 3. Let air conditioning refrigeration operation for 30 minutes, do check carefully. 4. The correct filling method, must take when filling, add a little to let air conditioning running after 10 minutes, and then test the pressure and current, unavoidably again by several times, not to as standard pressure and current at the time, in that case, may have been added. When winter to add fluoride, can disconnect the four-way valve coil, can also make indoor thermal head to open refrigeration can refrigeration temperature is reached. Sometimes also can let air conditioning in the dehumidification mode, it is not very tall to the requirement of temperature.
The elder brothers, can't invite invite! Refrigeration system is not a people, and hang some water had a bubble urine, much less, every day you make compressor resistance can be bad, look on the label, not according to the model. Or calculate it.
Refrigerant more is not a good thing, then the opposite effect
