Motor vehicle refrigerant how long is a normal, how to distinguish between motor vehicle air conditioning refrigerant missing?

if the summer air conditioning not refrigeration, this is an annoyance to owners friend. Of course, there are many reasons for this phenomenon. But the most reason about that is lack of refrigerant. So for refrigerant, friend how long should we use to add a? Our usual and how to distinguish? Below small make up as we say. Air conditioning normally open after a period of time was cold wind blow to the body and can quickly reach the set temperature outdoor tightening functions like a refrigerator operation moment stopped for an instant it's mark is normal. Otherwise it may demand the refrigerant. With the thermometer measurement indoor machine of inlet and outlet temperature difference in 8 ℃ above the bigger the temperature difference is normal to clarify the operation of air conditioning is more well up to about 15 ℃. The difference of less than 8 ℃ could demand added refrigerant. Opened the indoor machine during start up ten minutes on copper tube wear full aluminium panel should see evaporator on the part of the heat evenly is full of condensed water so less for normal high air humidity and vice. If half half no is likely to be short of refrigerant. As part of frost or ice is not normal. Users can use for more than six months survey of pipe joint and the house the valve if there is a significant sign of the spill. If there are any significant spill phenomenon indicates the machine has leaked fluorine miscibility due to oil leak will fluorine leakage fluorine will leak. When air conditioning continue to normal work, the glass hole continues to have bubbles, clarify the lack of the amount of fluorine, increase in demand. In air conditioning continue to work normally, glass hole without air bubbles, when the air conditioning to suspend, nor short time bubbles appear, clarify the amount of fluorine, emissions requirements. In air conditioning continue to work normally, glass hole without air bubbles, when the air conditioning to suspend, can present short time bubble, clarify the amount of fluorine is normal. If the owner did not find this glass survey hole, and a brief method can distinguish roughly: open car machine cover, check the air conditioning system joint have oil stains, if any, should be the lack of fluorine. Automotive air conditioning before add fluoride, demand of vehicle air conditioning system to do a whole inspection, to ensure air conditioning equipment not funnelled to add fluoride.

that's small make up to introduce the knowledge of refrigerant, understand the auspicious please open http:///
