Air conditioning use a long time, there will be a variety of problems, how to identify the lack of refrigeration systems fluorine? Should first open air conditioners, air conditioning compressor allows continuous operation for half an hour after the transformation of central air conditioning in Xuzhou, the following is summed up the problem: 1. From the outdoor unit charge fluoride mouth measured pressure is lower than 0.45MPa. The reason is lack of the refrigerant, resulting in the evaporation pressure drops. 2. dry pipe valve. Touch no clear sense of cool. The reason is the lack of fluoride, lead to the boiling point of the refrigerant within the evaporator to reduce central air conditioner, the refrigerant temperature increases the valve, the valve's temperature. 3. frost tube valves. The reason is the lack of fluoride, resulting in the liquid pipe pressure drop Xuzhou used central air conditioning recovery, reduce the boiling point of the valve to temperatures well below freezing. The outdoor unit exhaust no thermal. The reason is lack of the refrigerant, resulting in condensing pressure and temperature decrease. 5. Open the indoor unit panel, removing the filter, it can be found only a small portion of the evaporator frost. This is insufficient refrigerant cooling area correspondingly reduced results. 6. drain hose drain with little or no drainage. The reason is that the evaporator cooling area decreases Xuzhou brand central air conditioning prices, condensation area is also reduced, the condensation of water is reduced. 7. The outdoor unit gas liquid valve with oil. The reason is that the refrigerant and the refrigerant oil has certain mutual solubility, the refrigerant leak from the oil spill is attached around the leak. Analysis and Treatment Method 1. efficient air conditioning and refrigeration compressors, commonly known as the difference between a string of poor air. Fault current is now like a small differential pressure which means less downtime. The wind was blowing out of the machine instead of warm hot air. This fault only replace the compressor .2 heat well outside the machine. the machine duct nowhere. solution depends super simple. washing machine and a washing machine in the outer grille mesh point .3 is blocked. fault can now boot like refrigeration. But cooling block according to the length of time is a micro air conditioning in the whole block or blocking pressure will lift slightly unstable currents will change in size is also unstable. This fault most of the ice block. Add to impure water exceed the standard recycling fluorine whole block The pressure will drop. or until negative pressure until the current increases over current thermal protection. This failure is fouling more normal use of the machine is extremely rare. This failure occurred in the compressor replacement. removed machines process is not standardized operations Or stagnant for a long time not to install a small animal brass impurities Remedy:... block is like at a variety of block ice block in which the oil fouling the kind of does not matter because the exclusion method is the same as normal. running to the outside of the machine until the high-pressure pipe temperature drop when a cool breeze blowing. Always turn off the high pressure off the raft again to close the low pressure off the raft at the same time to turn off the air conditioner off. refrigerant in air conditioning and fluid bottle connection port. Unscrew the high-pressure pipe connection cap the use of refrigerant gas refrigerant gas bottle reverse blow pipe. (If there is best in nitrogen, but in fact there are several maintenance of the master may bring this nitrogen bottle) after blowing through'll find in impurities such as water. In connection back In the test machine. No repeated several times until no blocking .4 gas block. Failure is like a compressed gas temperature is high. gauge high unstable current is large. Refrigeration is poor. This failure is when you install more air is not ranked . Clean This is like only came fluorine evacuated add new quantitative fluorine Common symptoms of central air conditioning (1), drain: refers to refrigerant leakage; electrical (wiring, body) leakage and other damage caused by the insulation... (2), block: refers to fouling and plugging the ice refrigeration system; air filter is clogged; air inlet and outlet are an obstacle blockage. (3) off: an electrical line break; fuse blown; due to overheating or excessive current overload caused by the contact is open; the cooling system pressure caused by abnormal pressure switch contact is opened and the like. (4), burn: refers to the compressor motor windings, fan motor windings, solenoid coils, relay coils and contacts, etc. are burned. (5), the card: a compressor means jammed, jammed fan, moving parts of bearings jam. (6) damage: broken finger compressor valves, piston scuffing, fan blade fracture and various parts breakage.
