Air conditioning and refrigeration installation air conditioning decline for several reasons not mind, craft mouth screw not tightened, causing refrigerant leakage. As long as this problem tighten the screws, and then make up the refrigerant line. Air conditioning dirty. If the air conditioner is dirty it will result in heat well inside and outside. Like this relatively easy to solve. As long as clean air will solve the problem. Air conditioning refrigerant shortage, will also affect the air conditioning and refrigeration. Since the cooling system leak participate within the system thermal cycling refrigerant (refrigerant) insufficient, resulting in decreased efficiency of heat exchange, resulting in insufficient cooling capacity phenomenon. This Just fill plus snow on it. After long-term use of air conditioning compressor aging, power increases air conditioning, energy efficiency decreases, resulting in performance degradation, such problems have no good way, only the air-conditioning system for processing Xuzhou conditioning maintenance, change the air filter, replace compressor oil. (Note: different grades, grade compressor oil Do not mix). If not, you can only replace the compressor or buy a new air-conditioning. Analyzing the basic method of household air-conditioner common faults are: see, hear, touch, test, analyze. 1, see: Carefully observe the work of the various components of the air conditioner, air conditioning repair Xuzhou, focusing on observation of the refrigeration system, electrical system, air system three parts, determining 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, generally less 50DB. 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. Q: The biggest difference with ordinary air-conditioning inverter air conditioner where? A: inverter air conditioner has several key features: First, the special inverter device, which is what we usually refer to the inverter, which includes rectification, filtering, power output, electromagnetic compatibility control unit. Second, the inverter compressor, its motor with ordinary fixed speed compressor motors used different Xuzhou air conditioning, the main three-phase induction motor or permanent magnet motor, which is what we usually refer to AC inverter compressor DC inverter compressor. Third, the special ability to change the design of inverter air heating and cooling systems. Fourth, the advanced performance of the central processor, ensure inverter air conditioner according to the user's needs, environmental conditions, the state of the air conditioner automatically adjust their output capacity to ensure that the inverter air conditioner can be comfortable, energy-efficient, reliable operation. Those who meet the above inverter air conditioner a few key features can be said to be true of inverter air conditioner. As for the inverter air conditioner excellent performance parameters or not is determined by the manufacturers design level. No basic knowledge of inverter air conditioner inverter air conditioner repair people would say is not only using the inverter compressor and the corresponding control unit air conditioning, refrigeration Sheng Erda, Xuzhou waste conditioned by Xuzhou 圣尔达 Refrigeration Electrical Services Limited.
