How to buy an inverter air conditioner? 5

1. Determine the size of the air conditioner according to the size of the room, and at the same time, comprehensively consider the sealing and thermal insulation conditions of the room, floor, orientation, height and other factors.

Generally, household refrigeration can be calculated according to the cooling capacity of 130 180W per square meter, and the heating can be calculated according to 150 200W.

2. Determine the type or energy efficiency ratio of the air conditioner according to the frequency of use and the length of each start-on time. If the frequency of use is high and the time to turn on each time is long, it is more appropriate to buy an inverter air conditioner or a fixed-speed air conditioner with a high energy efficiency ratio, but if the frequency of use is not high, and the time to turn on each time is not long, you can buy an ordinary economical fixed-speed air conditioner.

Inverter air conditioner can give full play to its power-saving advantages only in the case of a long time each start-up, if the start-up time is very short each time, it can not reflect its power-saving characteristics, and even consumes electricity more than ordinary air conditioners, but the inverter air conditioner refrigeration and heating speed is fast, the indoor temperature difference is small, and the comfort is good, which is incomparable to ordinary fixed-speed air conditioners.

Hisense inverter air conditioner is the first to promote Hisense inverter,Hisense is the earliest manufacturer of inverter air conditioner in China,The quality is relatively warm,After-sales service is also more guaranteed。

It is best to choose a brand with a long warranty period for the whole machine.

Don't be a beauty pageant, the quality is very bad, I was fooled once, the new air conditioner was scrapped in 17 hours, and I didn't buy the beauty after returning it to the store. The best I've used myself is Daikin's. Tested with a power meter, a 2500 hp machine has a power fluctuation in the range of 1500 300 watts.

The so-called frequency conversion is to use the voltage change output of the temperature sensor to control the thyristor to change the conduction angle to change the input of compressor power.

Buy inverter, beauty pageant. I think it's the best in the domestic market right now. You can refer to it.

Are inverter air conditioners really better?

How to choose an inverter air conditioner? Inverter air conditioner purchase skills

Inverter air conditioner has now spread all over the major sales markets, as a new type of Chang closed Hu product, because the inverter air conditioner is a high-tech product made of computer-controlled inverter and inverter compressor configuration car, most consumers are afraid that they still know very little, so how to buy inverter air conditioner? Below we will bring the purchase skills and precautions for the use of inverter air conditioners, I hope it can be helpful to you.

Purchasing skills of inverter air conditioner:

1. When purchasing, determine the size of the number of horses of the selected inverter air conditioner according to the room area (generally one inverter air conditioner can be used in a room of about 14 square meters), and try to avoid using it in the case of over-area.

2. When purchasing, see whether the technology is mature. At present, a number of Chinese air-conditioning companies have launched their own inverter series products, but also took a lot of beautiful names, however, under the financial crisis, consumers are becoming more and more rational, simply with a "inverter" label to attract consumers The era has passed, then Naoban needs to come up with "real skills" - mature core technology.

3. When purchasing, see whether the quality is stable. Quality is the lifeline of products, and high-quality products can be based on the market for a long time and accepted by consumers. For the "new favorite" inverter air conditioner, its quality stability is largely related to the maturity of the technology.

However, the quality of the product is not up to par and needs to be verified by a third party.

4. See if the service is professional. For inverter air conditioners with complex technology, low-level "shush cold and warm" can no longer meet the needs of consumers, and professional services will become another indicator for consumers to choose air conditioners.

Precautions for daily use:

1. In the process of daily use, when the refrigerant needs to be added, the air conditioner should be set to run in the trial mode or the inverter compressor should be adjusted to work at 50Hz by adjusting the set temperature, and then the refrigerant should be added according to the amount.

2. The outdoor unit of the inverter air conditioner has a microcomputer-controlled inverter, and its printed circuit board is easy to be damaged in a high temperature and humid environment, so the outdoor unit should be installed in a dry and ventilated place to avoid sun exposure and rain. If the outdoor unit automatically stops after starting, it should be stopped immediately for repair to avoid the expansion of the fault.

3. Do not set the temperature too low in daily use to avoid the air conditioner from running at high speed for a long time. It is best to set it up in automatic operation mode, which can both quickly cool down and save electricity.

1. Choose brands and merchants: Huaicha enterprises that produce brand products have a large scale and output, and have a complete set of quality management system and product quality.

2. Visual inspection: visual inspection of each part of the air conditioner should be finely processed, the surface of the plastic parts should be smooth and smooth, and the color should be uniform. The surface of the electroplated parts should be smooth, and there should be no defects such as falling and scratching.

The surface of the sprayed part does not indicate that there should be bubbles, traces, and omissions. The primer layer is exposed, uneven and uneven. The installation of each component should be firm and reliable, and the pipeline and the components should not rub or collide with each other.

3. Vertical and horizontal wind deflector inspection: the manual vertical and horizontal wind deflector should be able to be toddled up and down or left and right, not too tight, not too loose, should be dialed in any position can be positioned, should not be automatically shifted.

4. Choose the type according to the actual needs: household air conditioners are divided into three types: window type, split wall-mounted type, and split floor-mounted type according to different installation methods or structures. Generally, the family bedroom is split wall-mounted, and the living room is split floor-to-ceiling.

5. Filter inspection: The filter screen is a part that is often disassembled and assembled, and it should be checked whether the disassembly is convenient and whether it is damaged. Check the function keys and knobs, etc.
