I bought three air conditioners. In march 2012, gl. 1, 25p, r. I. A., r. I. A., 2720. Room size 14 square. In february 2016, rainbow 1 and 25p, one energy-efficient air conditioner at fm-1 at $2890. Room space is 15 square. In february 2017, one energy-efficient air-conditioning unit at variable frequency level, 2850 yuan, at rainbow 1 and 25p. - now i live in two long rainbow air conditioners. One of these is a long rainbow air conditioner that moves through the two-time machine without refrigerant, and the cooling and heating effects are still good. - i bought gla at first because i heard that gla cooled faster than a rainbow. Because it was a fixed-frequency air conditioner, and my house was sealed and insulated. I'm very sensitive to the heat and cold. In july and august of each year, an average of more than 10 air conditioners per day on the switch, which was a bit annoying, gave rise to the idea of buying one. Because of the power of the first air conditioner, it's less worrying about the so-called slow cooling. I see a long-winder frequency air conditioner that can be zero, one-twirth temperature control. This is not a function of other air conditioners. I asked again. The salesman says it's all copper. That is, i believe, because copper prices have fallen by almost half since the global economic downturn in 2008. After all the trade-offs, i decided to buy a long-winder frequency air conditioner. In practical terms, my choice is right. Long rainbow air conditioners are not slow to cool, and silent effects are good. There is also a unique element in energy conservation: first, not only does heat make fast, but temperature fluctuations do not exceed zero or minus one degree (without complementary heat). Second, the energy efficiency ratio for the refrigeration and heat preparation (without coheated heat) of long-iron variant air conditioners is above 5. Thirdly, the long-winding frequency air conditioner is only zero, 1w. In addition, evaluating an air conditioner depends on its after-sale service. I have a glf air conditioner, which cannot be refrigerated as a result of the retrofitting of the sanitary city, which resulted in the transfer of the construction personnel with no refrigerant. Using personnel to report to me (in the middle of this year's high and middle examinations), i called gryth maintenance department several times without a call, and finally i got a long-winder. — and one more thing is important. An air conditioner is inefficient, has a long life and does not easily cause problems, and, in addition to the quality of the air conditioner itself, there is a great deal to do with its proper use. One of the most important things is the sealing and insulation of the house. How the house is insulated, please follow my previous responses。
