If possible, buy a new air conditioner. On the market today, electronics supermarkets often launch many attractive incentives to attract customers. Accordingly, many 1- or 2-way air conditioners with a capacity of 9,000-12,000 BTU are being discounted to only 4-10 million VND per unit. New air conditioners are cheaper and cheaper, modern technology should save more electricity. Hanh Nguyen (Synthetic)

Many people still think “cheap is mine”, so they don’t buy cheap air conditioners. However, according to experts, the cheap air conditioner line also has its own advantages. The immediate advantage is that users can reduce a large amount of money to buy a machine. Cheap air conditioner models are mostly one-way air conditioners. One-way air conditioners usually cost half as much as two-way air conditioners. Meanwhile, the cooling feature of one-way air conditioners is no less than two-way air conditioners. Models of one-way air conditioners often have a radiator in the “hot block” made of mainly aluminum, anti-rust paint. The advantage of this material is its low cost and fast heat dissipation. These air conditioner models usually have a capacity of about 9000 BTU, suitable for small area rooms. Cheap air conditioners are mostly one-way air conditioners that only have cooling effect, suitable for hot summer weather. In places where the climate is hot all year round like the South or in the North where “winter is not cold”, buying a two-way air conditioner may not be necessary. Moreover, the use of one-way air conditioners will help save costs. In addition, cheap one-way air conditioners also have the advantage that during use, if damage occurs, the repair and replacement of components will be easier and less expensive. One problem that many people wonder is that cheap air conditioners are not equipped with inverter technology (air conditioners with energy-saving technology). However, according to experienced people, if the daily use time is less, it is not so important to have energy-saving inverter technology, while the price of inverter air conditioners will be 2-4 million VND more expensive than the average. with conventional air conditioners (without inverter technology). Inverter air conditioners often save electricity effectively with a continuous use time of 6-8 hours. If the time to use is less, you should choose to buy a one-way air conditioner. If you have the financial ability to buy high-end air conditioners at expensive prices, it will be very good. But with a tight financial situation, cheap, energy-saving air conditioners are still the best choice for many consumers. In fact, whether the air conditioner is good or bad depends not only on the air conditioner, but also greatly depends on the installer’s technique and the consumer’s usage. Therefore, when choosing a cheap air conditioner, consumers need to pay attention to choose to buy genuine quality air conditioners, with a professional warranty system. Buyers also need to refer to the power consumption parameters on the air conditioner product label. At the same time, customers should also find products that are suitable for their finances, installation conditions and usage needs.

This time started in the summer, the demand for cooling devices increased, leading to a dizzying increase in electricity bills, so solar fan models were sold on the market. They are advertised, instead of running on electricity like conventional types, this type of fan operates entirely on solar power. Specifically, each solar fan will come with a solar panel to help absorb sunlight and produce electricity to maintain operation. Depending on the type of panel, when placed in the sun, the fan controller will charge the battery, which takes 4-6 hours. After the battery is fully charged, the fan will work for 6-10 hours continuously, even on rainy days without sunshine. In addition, users can use grid electricity to charge the battery for storage and use. Solar fans are causing fever in the market this summer Currently, on the market, these fans come from many places such as: China, Korea, Vietnam, … with very diverse prices, depending on size and function. In which, the lowest price is about 200,000-300,000 VND (mini fan), tree fan costs 800,000-2 million VND. Many fan lines are being discounted by 20-50% to attract buyers. For example, the 20W mini solar fan line is being discounted by up to 50%, from VND 830,000 to VND 417,000; mini fan 3.5W X9E is 40% off, from 510,000 VND to 306,000 VND; The Sunisi FT-30 fan model is priced at 1 million VND, 50% less than the original price of 2.1 million VND; Korichi KRC 6300 fan model reduced from 1.2 million VND to 890,000 VND; Jenpect 220V fan model has the original price of 1.3 million VND, down 34%, now only 850,000 VND,… According to the advertisement of the staff of household electrical stores, compared to traditional fans, solar fans have many advantages such as: no electricity costs, no fear of sudden power outages in hot summer days. Not only that, they are also very convenient when going on a picnic or camping trip; can directly charge other mobile devices such as phones, flashlights, … via USB port, which is very convenient. Moreover, long battery life 3-5 years of use, battery capacity up to 12,000 mAh, using time up to 8-12 hours. With “divine” functions, especially without consuming electricity, this type of solar fan immediately caused a fever in the market and was sought after by many people. Mr. Nguyen Hung – an employee of an electronics store in Ho Chi Minh City – said that at this point, the demand for cooling fans has begun to increase sharply, in which the solar fan line is the best-selling model. . As at the beginning of summer, his shop sold about 300 solar fans, at the peak of last year’s heat, he sold up to 800 units. Many fan models are having super cheap prices to attract buyers Similarly, Mr. Hoang Van Binh – an employee of an electrical appliance store in Thanh Xuan (Hanoi) – also said that in recent years, the price of electricity has tended to increase, people have the need to buy and use electricity. Use energy-saving appliances and take advantage of natural energy sources. Therefore, from May, customers looking to buy solar fans are busier. Currently, he only has 15 more fans to sell out. According to him, this type of fan is often suitable for low-rise houses, level 4 houses rather than high-rise buildings and apartments like in the city. Because the fan and solar panels are separate, it is necessary to choose a location to mount the panels to catch the sun (roof, rooftop, balcony, front yard, …) then connect to the fan set. Therefore, with high-rise buildings, moving equipment is quite difficult. But Binh also admitted, when it rains, the charging capacity of the fan will be poor, so in the prolonged rainy season solar fans will not be able to promote their full benefits. At that time, the fan can still be used by the grid as usual. Talk to PV. VietNamNet, Mr. Le Van Kien – a technical staff member of an electrical appliance store in Khuat Duy Tien (Thanh Xuan, Hanoi) – shared, when buying a solar fan, it is necessary to pay attention to the lifespan of the panels. The origin of the battery is unclear, poor quality will make the fan’s performance worse, the fan runs erratically, the lifespan is reduced, and it pollutes the environment. Moreover, the life of the battery is usually only 2-3 years, then it has to be replaced at a considerable cost. In addition, the capacity of the battery will determine the operating time of the fan, the battery is designed with a high capacity, the better the charge will be and vice versa. Limit the selection of multi-function rechargeable fans that are equipped with lights, alarms or clocks… because these features consume power from large batteries, making it easier for the battery to fail faster. Users should not be greedy, but buying low-quality fans will have many potential risks, so consider when choosing and need to choose to buy products of reputable brands and addresses.
