Thermal protection repair the air conditioning and fluoride old! Today to an air conditioning and fluoride, air conditioning, a little old, about 2 o'clock in the afternoon. Plus a little bit. 0.3 gauge, ammeter 3.8A. Then add a few moments, the gauge 0.4 meter beyond the rated current of 4A 4.2 meter nameplate off valve table, suddenly blooms current 7.2A, next to the thermal protection. Then emptying the master table when the table is negative did not notice. Unscrew the screws fluoride tube, which may enter the air. Causing the ice block. It stopped after two hours, air conditioning repair, open space survey meter gauge 0.3 2.6A Xuzhou industrial air conditioning repair, then add a little bit to open the valve, pressure gauge 4.5 meter 4.2A dare added. Just above the three-way valve and a small amount of frosting finish. Should still have a little lack of fluoride, but the current is already high, what is the press is faulty, or capacitance effect declined? Or are there other reasons? (This machine is cold before the exchange, now replaced by cooling only, fan and compressor using a power cord) Sheng Erda air conditioning repair center to remind you: two reasons outside electrical and mechanical wind capacity is not enough, there is the compressor problem. Refrigeration Electrical Services Ltd. Xuzhou Sheng Erda door, expensive, a lot of recycling, the acquisition of old and new air conditioning, second-hand air conditioners, stock air conditioners, air conditioning offline confiscated air conditioning, auctions air conditioning, good or bad air conditioning. Our private enterprise, flexible Xuzhou air conditioning maintenance and fluoride, for the state-owned enterprise responsible for recovery is good or bad air conditioning, fashionable and attractive, cash recovery. Welcome to the major air conditioning manufacturers and related units have a backlog anti-plant machine operators closed down inventory, smuggling confiscated, and other contact with me, honest, optimistic about the goods cash on demand. Analyzing the basic method of household air-conditioner common faults are: see, hear, touch, test, analyze. 1, see: careful observation of the various components of the air conditioner work, focusing on observation of the three parts of the cooling system, electrical system, air system, determine whether they are working properly. 2, listen: listen to power on whether the air conditioner compressor operation sound is normal, abnormal noise, the fan is running without noise, the noise is too big. The air conditioner in operation, under normal circumstances a slight vibration, noise smaller Xuzhou conditioning maintenance, generally 50DB less. If the vibration and noise is too large, possible causes are: 3, touch: touch the air conditioner parts feel its cold, vibrations, etc., to help determine the nature and location of the fault. 4, test: In order to accurately determine the nature and location of the fault, often use Instrument check the measurement performance parameters and status of the air conditioner. Such as the use of refrigerant leak detector to check for leaks; use a multimeter to measure the power supply voltage, the connection terminals for ground current and operating current to meet the requirements, the computer-controlled air conditioner, but also measure the potential of each of the control points is normal and so on. 5. Analysis: After the results of the inspection of several means obtained, most can only reflect some local state. Is another link between the various parts of an air conditioner, influence each other, a failure phenomenon may have a variety of reasons, but one reason may also have a variety of failures. Therefore, the local factors to conduct a comprehensive comparative analysis, in order to fully and accurately determine the nature and location of the fault.
