Chiller maintenance as follows: 1, check the oil pump lubricating cup tank is normal, bearing for wear duct cleaning prices, problems in time to replace oil or bearings. 2. Check the pump shaft seal leaks air duct cleaning, is functioning properly, the machine foot loose bolts, check whether the import and export of valve leakage. 3, check the cooling tower is working, bolts Tangshan air duct cleaning, machine foot bolts loose rust, pipes and automatic electric valve operation without fault. Why air conditioning and fluoride? Flon is air conditioning and refrigeration system heat transfer medium. Without it, the heat can not be effectively exchanged. Air conditioning can not cooling or heating. Therefore, once the air conditioning lack of fluoride, outward manifestation of the cooling (heating) effect is poor, not cooling (heating), protective shutdown, the indoor unit leaks (sometimes water), the machine evaporator icing. The more the surface do not see a problem - reduce air conditioning life, a waste of electricity, damage the air conditioning compressor. So, we need a normal use of air conditioning, there must be sufficient flon.
