Is this really power-saving?
Contact brand staff for door-to-door maintenance;
The japanese media network reached out to brand members for maintenance; on july 21st, a hot day of news: our lives were air conditioned. But the air conditioners are on for a long time, the meters are moving fast and the electricity costs are not cheap. Some of the ads for fm air conditioners say, "it's only a once-in-a-night call," and does it really save so much?
Summer is the hot season of air conditioning. Currently, air conditioners sold on the market are broadly divided into fixed-frequency air conditioners and variable-frequency air conditioners. Entering the brand cabinet, salesmen enthusiastically marketed their fm ac to journalists. According to the sales staff, the price of variable frequency is more expensive than the normal fixed frequency for air conditioners with the same brand and specification。
Journalists visited and found that the prices of fm air conditioners in almost all branded air conditioners were higher than the price of rfa air conditioners, some more than 1,000 per unit. A large number of salesmen are willing to market uf air conditioners, and at the time of the sale* the headline is more power-efficient。
The salesman: “it must be better to change the frequency, save the electricity, and this one is 1. 25 p. M., two times a night.”
Is it really possible to save electricity? The salesman for branded air conditioners put it bluntly, but it is not so exaggerated。
Brand-based air conditioners present that regular fixed-frequency air conditioners (rfas) of 1. 5p are about one degree of power in two hours, and that a variable-frequency air conditioner can save some amount of electricity if it is used over a long period of time, but not necessarily in a different type。
It costs hundreds of thousands more than normal air conditioners, and probably most consumers are running to save electricity. But will the facts really be as publicized by the sales people? Industry sources say that the so-called energy efficiency savings of variable frequency must meet certain conditions, or else it will be more power-consuming than normal fixed-frequency air conditioning。
Mr. Wang said that the fmac was introduced by salesmen and that the actual use of electricity in china province did not allow himself to visit the meter。
According to industry sources, variant air-conditioning, by definition, is a compressor whose frequency can be converted to a modem, and the general variable air-conditioning energy efficiency saver 4 connects brand members to home maintenance; around % does have an advantage in saving energy and electricity. But there are prerequisites for it to reach the frequency。
The department of electricity, liu fong, is located in the supermarket: “the room cannot exceed its area of use, nor can the second temperature exceed the high temperature, so that the same conditions are met before a frequency is achieved”
If these two conditions are not met, liu fong explained that the fm ac is not only less energy-efficient, but even more power-consuming than the normal ac。
Liu fong: “in the event that the room is too large, you buy a variable-frequency air conditioner, the compressor doubles the rotation, thus creating a very high load on the machine, so that the amount of electricity consumed will multiply and the life of the second machine will have an impact.”
In addition, air conditioners also explained that the low level of electricity as low as once a night did not mean that one night was required to be used only once, but rather that, according to laboratory data, air conditioners consumed electricity under the eco model。
Salesman shezzy: “many people think that our air conditioners advertise as low as once a night, and they think that they can do it once a night from the start, which is not the case, and that's an energy-saving temperature-saving model.”
Industry suggests that the choice of frequency and fixed-frequency air conditioning can be bought by consumers on the basis of their economic capabilities and needs. The purchase of air conditioners is based on the choice of a specification type relative to the size of the house,* the mode of saving electricity is to move indoor temperatures to a suitable temperature of 26 degrees for humans.*。
Shezzi: “purchase air conditioning, first * point, depending on the room size, i personally suggest that 12 or three square metres, with 1. 25 p, 14 or 5 squares plus 1. 5 p, and 18 squares larger than 1. 5 p.”
The chief physician of internal medicine at the city's 2nd hospital, dr. Xiaochun tang: “the clinical manifestation of air conditioners, which causes deafness, even dizziness, and pain in the muscles of the limbs, is often the case where many patients think they have a cold,* which is effective when they take something like fragrance or fragrance
The doctor suggested that people should properly open their windows for ventilation every two hours or so in the air-conditioning room. In case of increased physical discomfort, they must be treated in a timely manner。
