The rfa air conditioner is now more common, but the more energy-efficient version of the rfa has been slowly replacing the rfa air conditioner. In the process of using air conditioning, whether it is an intuitive or a variable air conditioner, we should be aware of their basic common sense and skills。
The problems encountered by variant air conditioners are not only that of non-refrigeration, but also that of permeability of air conditioners in indoor air conditioners and the sound of air conditioning operations. We should look at the main reasons for the abnormalities in air conditioners. In conducting air conditioning repairs, we can test air conditioners using the following methods:
1. When air conditioners fail, we can first see if there is a problem with the interface of air conditioners indoor air conditioners and outdoor air conditioners, and at the same time see whether there is dust on the wafers of air conditioners and then see if there is any problem with the operation of air conditioners indoors and exterior air conditioners. See if the compressor's gas pipe is frosted, whether the condensing and filtering systems are frosted, whether the catheters are blocked, etc. The air conditioner failure code shown on the air conditioner display screen can also be inferred from the air conditioner failure code。
2 in addition to the need to view the common malfunctions of the air conditioners, a hearing may also be used to detect them. The first thing we can hear is whether the air conditioners outside the air conditioners and the fans of the air conditioners indoors are running smoothly, and whether the compressors are operating with squeaks or with a concussion. Then listen to the sound of condensant seepage after flow。
3. Security checks can also be conducted by listening to and seeing later, with the primary aim of cognizing whether the temperature of the various components in the course of work is normal, so that we can check whether the frequent malfunctions of the air conditioner are caused by the high temperature in operation。
The main purpose of the smell is to smell the internal and external electromagnetic wires of the ac compressor, while asking whether the circuit boards, electromagnetic valves, power modules smell. The method of smelling is also intended to make it possible to determine whether, in the course of its use, air conditioners are stenched by the burning of a component because the temperature is too high。
The basic six-point overhaul of air conditioning is:
I. Not to commence immediately upon arrival. Otherwise, the compressor would also have a hydraulic condition that would cause the destruction of the parts and endanger the compressor's useful life. (also referred to as protective devices) can automatically act as a buffer. It is normal to restart a fully intelligent three-minute maintenance timer within three minutes of a three-minute smart air conditioner。
Ii. The air conditioner runs in the first ten minutes, sometimes with the sound of a split. Air-conditioning case raw materials use thin milk and white-coloured plastic, which is lighter in weight and more elegant in shape, but is caused by changes in temperature, heat rises and cooler physical changes, so the air conditioner splits. It's not a common malfunction。
Three, the air conditioners run, and some of the products are unwittingly generating water-like sounds. It is also an air-conditioning operation in which the refrigerant situation continues to change from liquid to gas and then to liquid. It's normal for normal physical changes to occur at a certain speed in a chiller unit, and because of some friction resistance, there's a flow of water。
Iv. Send a slight smell of wind. Some believed that the air conditioner sent the stinking cold because of the freon leak. But the fact is that ac freon is non-smelling, and the smell comes from indoor smoke and other stinks. New types of air conditioners, which use activated carbon-efficient filters to enhance adsorption, not only remove fine dust particles, but also remove the fumes and other stinks of smoke, resulting in significant improvements in air filtering。
5. The temperature in the room cannot be reduced. The first test is whether the air conditioner's venting and venting temperatures are abnormal and, if normal, indicate that the air conditioner is not in question. The reasons for this may be due to the large number of indoors, too much heat, high outdoor temperatures, open windows, tight curtains, hot pads around air conditioners and frequent door openings。
When cold operation occurs, natural ventilation of air-conditioning indoors is hampered and the wind is not cold. New air conditioners typically use three layers of filters, i. E. Detergent nets, electrostatic filters, activated carbon filters, relatively high filters, which have a strong ability to depurate the air of dust particles with very small apertures, but less time for filter cleaning. If they are not cleaned in time, the eyes of the net are blocked and the temperature reduction is slower。
