Answer: 1. Haier Olympic Smart Style KFRD-50LW/RA1(F)-S5 with electric heating

2. Haier Quiet Olympic Style KFRD-50LW/C(F)- S4 with electric heating

3. Haier 08 Olympic style KFRd-50LW/A (QXF) with electric heating with fresh air

4. Gree King of Kings KFR-50LW/R (50533L) Without electric heating

5. Midea Tianjingxing (P type) KFR-51LW/DY-P (E2) without electric heating sliding cover: it is fully automatic and automatically turns on the cooling capacity required for your room: 35 (room area) * 140 (cooling coefficient) = 4900W. In other words, 2P is just right. The 50 and 51 in the air conditioner represent the cooling capacity of 5000W and 5100W. 6. Energy efficiency ratio is the nominal cooling capacity. The ratio of (heating capacity) to operating power you choose is a fixed-frequency air conditioner, and the energy efficiency ratio is almost the same, basically not energy-saving. The current energy-saving air conditioners are variable frequency air conditioners. Variable frequency air conditioners are divided into DC and AC variable frequency. Of course, DC is better and more energy-saving.

7. Whether it can be cleaned automatically is just a buying point for the manufacturer and is basically meaningless.

8. Air supply distance and air conditioners have different wind speeds (usually 4th gear). Of course, the greater the wind speed and the farther the distance, the better the effect.

9. Since you don’t need heating, you don’t need to consider an air conditioner with electric heating.

10. The cooling and heating speeds of the air conditioners you choose are all about the same. Of course, the higher the wind speed, the faster the cooling. (The cooling speed of the inverter air conditioner will be much faster)

11. Silence, and the eighth and tenth items are from Mao Dun. That’s why inverter air conditioners were invented.

Finally, I would like to give you some comprehensive advice: you have chosen the most powerful brand in China. They are all very good, but there are still differences between them.

Gree: The quality is very, very stable. I have repaired air conditioners for so many years, and I have never seen Gree repair it due to quality problems. In particular, Gree’s refrigeration system is the best in the country. . So I really recommend that you should consider Gree first.

Haier: China's world brand, the brand is very big, the quality can only be considered as qualified (reason: Haier develops too many products, especially air conditioners, and then improves them after user problems arise, so, Be careful when buying new Haier products. Haier's best products are: washing machines and refrigerators, these two products are Haier's flagship products).

Midea: Average, neither good nor bad.

If you don’t understand anything, you can leave me a message.

Reply to the message (I can’t reply in the space, so I will reply here):

First of all, the air conditioners you choose can heat, so you don’t have to worry.

Automatic cleaning is useless, because after cleaning, some dust will be blown out from the air outlet, but you can't feel it. It is better to clean it manually before use every year, which is good for your health.

Smart defrost is of little use to you, because this function can only show its little advantage when the outdoor temperature of the air conditioner is -5 degrees.

Although variable frequency is better than fixed frequency, it is indeed not as stable as fixed frequency. Apart from not saving electricity, choosing a fixed frequency machine is pretty good.

I have answered the noise question for you. Sound and cooling effect are inversely proportional. So you can choose automatic wind speed and let the air conditioner find the most suitable wind speed by itself.

Now the after-sales service of Gree and Midea is on par with Haier. Also, you'd better buy it from a large merchant such as Suning Appliances, because they also have after-sales service, so you're double insured. Moreover, Suning’s after-sales service is also on par with Haier’s. Haier has a famous saying: Whatever users are wrong is right. The above four companies all use this sentence as a standard to serve users.
