When need to replace car air conditioning refrigerant?

a, blowing test

normal open air conditioning, after a few minutes was cold wind blow to the body, and within the time must reach the set temperature, it is normal. Or you need to find a professional inspection car air conditioning system, check whether the demand increase refrigerant.

2, with a thermometer measurement temperature

with the thermometer measurement of air conditioning indoor machine of the temperature difference between the inlet and outlet temperature difference value for normal in 8 ℃ above, the bigger the temperature difference of air conditioning work, the better, usually up to about 15 ℃. The difference of less than 8 ℃ could demand added refrigerant.

three, boot survey

in the boot after more than ten minutes to open air conditioning indoor machine panel, see the evaporator tubes in cold heat exchange on the part of the uniform is full of condensed water such as normal, the humidity of the air condensed water more and less instead. If half half no is likely to be short of refrigerant. Part of frost or ice is not normal.

4, test indoor machine

use of more than half of users can observe the pipe joints 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, because the oil will leak fluorine fluorine miscibility leakage, and leakage fluorine will leak.

in addition to the above practice discriminant method, professional personage warns customer, if the air conditioning refrigeration effect is not ideal, is bound to please the professional auto maintenance personnel for testing before to distinguish whether demand increase refrigerant ( Add fluoride) To increase the refrigerant, don't blindly.

how to choose automobile air conditioning refrigerant?

chemical give you hint: at present, the automobile air conditioning refrigerant used is everything. A, to select factory original refrigerant or pure R134a has a cold, so best to maintain air conditioning compressor, used as refrigerant substantially reduced the life of the compressor, air conditioning system leakage, owners who form severe losses. We can through the packaging printing, anti-counterfeiting trademarks, from detail to distinguish authenticity, such as not complete must not is produced by the factory,

2, depends on the brand, owner had better choose quality safe car refrigerant, such as dongyue, meilan, three beautiful big brand. Small shop less known and inferior brand is more, the owner can also through different brand product weight contrast to judging the quality of the refrigerant, defect, lack of posing as refrigerant general component.

Service-based companies as Hangzhou E cool refrigeration Co.,Ltd are increasingly becoming more popular internationally.

Exceed customers' expectations in the procedures of manufacturing air conditioner capacitor.

For optimal start capacitor suppliers, choose a high-quality refrigerant gas system and make sure a certified installer sets it up.
