Weak current College】 【inverter air conditioner's shortcomings.

<br> <br> First, for Europe and the United States, most families used to put air conditioning open all day, and even has not shut down, because they want a room you can achieve the effect of heat or cold, but also .because their price relatively inexpensive. And for our country, most families will not have air conditioner, inverter air conditioner of advantages, not because the inverter air conditioner is called air conditioning has been running in order to achieve the purpose of saving power. <br .> <br> Second, the inverter air conditioner's technology is not perfect. Although the business advantages of frequency of hype, but everyone knows that the more advanced machines, the more complex parts, defective probability will increase (of course now, because we all .manufacturers of inverter technology has not reached a relatively high level, and the frequency of the core components of the technology is still in the hands of Japan ...) <br> <br> 3. not so effective <br> <br> .First to calculate the cost of air conditioning use. For example, if the air conditioning in accordance with the use of time per year for three months, each month 30 days, 8 hours per day average run, refrigeration run time was 960 hours, on .average, in accordance with the air conditioning power 2000W, refrigeration, air conditioning with constant speed 5 (EER = 2.6) of the total electricity consumption of 1920 degrees, if you use the current Shanghai standard 5-level inverter air conditioner (EER = 3.3 .), total electricity consumption of 1510, saving about $ 410, each annual saving electricity costs only $ 150. However, the current price of inverter air conditioner than normal air conditioning price exceeds $ 1000! <br> <br> In addition to northern .cities, for example, many regions all have heating facilities during the winter, every year the use of air conditioning in season only three months, most of the time, frequency conversion air conditioning air-conditioning idle advantages and not obvious. <br> < .br> IV. maintenance and service life <br> <br> If you compare inverter air conditioner and constant speed air conditioning of outdoor machine internal structure, you can see the internal structure of the variable-speed air conditioning more complicated, internal parts almost .more than three-fold, and added a PCB. We all know, the more complex the structure of household appliances, accessories and more, in relative terms of life will be shortened. A related investigation, inverter air conditioner uses three years occur in a .variety of quality issues. <br> <br> To follow the air conditioning, for example, the inverter air conditioner provides a three-year warranty period, the compressor provides a five-year warranty period. To calculate the tariff before, if you .save $ 150, five years after use when electricity savings less than $ 1000, but when the product is out of warranty. This calculation, the air conditioning repair costs will increase again. <br> <br> Because of economic considerations, the advantages .of variable-frequency AC, thus greatly discounted present much of a thousand dollars to buy a inverter air conditioner is not worth it. Of course, from the energy point of view, air-condition does have certain advantages, but this is out of over .a thousand dollars is not going to let our consumers to? <br> <br> On the other hand, the inverter air conditioner product properties, it must be fast start, and then slowly to keep a slow-running state run continuously. So ., for those accustomed to the speed of the user, sometimes feel that air conditioning (heating) strong enough to fast enough. For usage, inverter air conditioner may not suitable for such use. <br> <br> Frequency selection and use of air .conditioning <br> <br> Because the inverter air conditioner is used by computer-controlled inverters and inverter compressor consists of high technology products, users in the purchase, installation and use, you should note the following: <br> <br> ① .in purchase, depending on the room area to determine the selected number of inverter air conditioner horse size (usually a horse can be used for the inverter air conditioner 14 square meters room), try to avoid using super area; <br> <br> .② in the installation, maintenance, you need to add refrigerant air conditioner should be set in the trial mode run or adjust the set temperature in a way that frequency compressors work to 50HZ State, and press join refrigerant; <br> <br> ③ .Inverter air conditioner of outdoor unit with microcomputer control of frequency converter, the printed circuit board in high-temperature and humid environment more easily damaged, and therefore its outdoor unit should be installed in a dry and ventilated place, avoid sunshine and rain. In the .event of a power on automatically after outdoor machine downtime, should be immediately shut down for repairs to avoid failures; <br> <br> ④ for daily use do not use the temperature setting is too low to avoid air conditioner with consistently high speed running .. The best setting in auto operation mode, so that both can fast cooling and power saving. <br> <br> ⑤ to buy, see the technology is mature. at present many of the Chinese air conditioning have launched their own frequency products, .and also took a lot of beautiful-sounding name, however, the financial crisis consumers increasingly tend to be rational, simple to a "frequency" tags to attract consumers age is over, you need to take out the "real talent" - mature core .technology. <br> <br> ⑥ purchase, look at the quality stability. quality is the lifeline of the product, high-quality products to long based on the market for consumer acceptance. For "new favorite" inverter air conditioners, quality stability .to a large extent on whether or not with mature technology have great relationships. But product quality not cross the border, you need a third party to verify. <br> <br> ⑦ see whether a service is specialized for the inverter air conditioner is .technically complex, simple "deficiency q warm" service has been meeting the needs of consumers, professional service will be the consumers select a further indicator of air conditioning..
