The structure and working principle of precision air conditioners Precision air conditioners are mainly composed of compressors, condensers, expansion valves and evaporators. Generally speaking, the refrigeration process of an air conditioner is: the compressor compresses the refrigerant gas that has absorbed heat energy after passing through the evaporator into a high-pressure gas, and then sends it to the condenser of the outdoor unit. The condenser transfers the heat energy of the high-temperature and high-pressure gas to the surrounding air through the fan. Release in the air to re-condensate the high-temperature and high-pressure gas refrigerant into liquid, and then send it to the expansion valve. Is there any abnormal vibration? Check whether the fan of the machine is on the same plane when rotating. ) Check whether there is any debris under the condenser that affects the smooth flow of the air duct, thereby affecting the condensation effect of the condenser. Check whether the fins of the condenser are damaged. ) Check whether the current when the condenser is working is normal. From the working current, you can further determine whether the fan is working properly. ) Check whether the speed control switch is normal. Generally, the condenser of an air conditioner has two speed control switches, which are divided into temperature and pressure speed control. Now the relatively new control technology uses dual pressure speed control, so we are checking the speed control switch. It mainly depends on whether the speed control switch can normally control the start and stop of the fan within the specified pressure range. , Patrol inspection and maintenance of evaporator and expansion valve. Maintenance of evaporator and expansion valve is mainly to check whether the evaporator coil is clean, whether there is frost, and whether the evaporator drain tray is drained smoothly, such as the evaporator coil If there is serious frost on the coil or the temperature on the coil is high when the compressor is running (normally, the temperature of the evaporator coil should be about ℃ lower than the ambient temperature), you should check the high and low temperatures of the compressor. Low pressure, if the pressure is normal, you should consider whether the opening amount of the expansion valve is appropriate. Of course, this phenomenon may also be caused by other environmental reasons, such as insufficient cooling capacity of the air conditioner, too slow wind speed due to fan failure, etc. , Inspection and maintenance of humidification system) Since the air environment in each place is different, the use and impact on the humidifier are also different, but the same thing we have to do during daily maintenance work is to observe whether there is any moisture in the tank. If there is sediment, it must be flushed in time, because the humidification tanks of air conditioners are generally electrode-type. If there is too much sediment and it is not flushed in time, scale will easily form on the electrodes, thus affecting the service life of the humidification tank. Of course, the electrodes of some humidification tanks can now be replaced. ) Check whether the water supply and drainage solenoid valves are working properly. During the operation of the humidification system, there is a situation that often occurs, but it is not easy to judge. That is, when the air conditioning system is working normally, the water supply is stopped for a period of time for some reason, and then the water supply is restored. The humidification tank cannot fill water normally. There are many reasons for this phenomenon. In most air conditioner control systems, directly resetting the humidification system usually cannot solve the problem. According to our maintenance over the years, the problem is caused by The main reason for this phenomenon is that the air after the water is stopped enters the front end of the water inlet solenoid valve, which has a certain impact on the normal opening of the water inlet solenoid valve. There are two useful ways to solve this phenomenon. One is to remove the The water inlet, draining the air, and secondly, turning off the power of the humidification system and re-energizing the solenoid valve can basically solve this type of problem.
