Air conditioning lack of freon? Air conditioning no freon how to judge?

that most people know that the air-condition freon is what material, said popular point is the refrigerant, so for air conditioning, refrigerant like car petrol, only when the refrigerant is enough, air conditioning can normal operation. So many people in the use of air-conditioning, often regardless of whether or not enough air conditioner freon, air conditioner freon is able to use all the alert all don't know, sometimes even air conditioning air conditioning actually without freon was more serious, so no freon air conditioning?

no freon air conditioning?

if there is no freon air conditioning will be very easy to broken, a great influence on the whole machine. In short, when the air conditioning use the refrigerant liquid exothermic, gasification endothermic characteristics ( Heat pump features) , compressed refrigerant compressor, refrigerant, respectively, the machine of the heat exchanger of liquefaction, gasification, refrigerant in the gasification and heat state machine, evaporator, refrigeration is, in a state of liquefied heat release is warm. This kind of air-conditioning system is also called heat pump air conditioning. And freon, is one of the refrigerant.

how to determine no freon air conditioning?

judgment, central air conditioning step one: the lack of fluorine try

air conditioning normally open after a period of time was cold wind blow to the body, and can quickly reach the set temperature, the outdoor compressor can open for a while like electric refrigerator stop for a while, can say that is normal.

judgment, central air conditioning of fluorine in step 2: test

use thermometer to measure the temperature difference between the inlet and outlet of indoor machine difference in 8 ℃ above is normal, the bigger the temperature difference of air conditioning work, the better, up to about 15 ℃.

judgment, central air conditioning of fluorine step three: read

in the boot after ten minutes, open the indoor machine panel, should see evaporator ( Copper tube wear full aluminium plates for heat exchange parts) The uniform is full of condensed water ( Like the dew) For normal ( When air humidity is big, more and less) 。 If half half, is the central air conditioning the performance of the lack of fluorine, such as local frost or ice are not normal.

judgment, central air conditioning of fluorine step 4: touch

as in the place where people can touch the outdoor, can be in the boot with hands after more than ten minutes. Seg has two copper valve door, a thick copper tube, a fine brass. With the hand touch two valves should be temperature difference; Coarse should be lower than the fine temperature, touch the relatively cool as normal, At high temperature also should be condensed water) , to touch the outdoor hot air is warm, also may be a manifestation of central air conditioning lack of fluorine.

judgment step 5: central air conditioning lack of fluorine was

users of more than half a year, you can check valve pipe joints and the house whether there are obvious signs of oil spill, if there are any obvious leakage or suggests that the machine has a leak, fluorine miscibility because oil, the oil will leak fluoride, fluoride will leak leakage.
