Pay attention to four look when buying air conditioners in summer

With the arrival of the hot summer, the sales of household air conditioners have entered the peak season. How to choose a satisfactory air conditioner correctly, so that consumers can enjoy the coolness brought by the air conditioner at high temperatures is particularly important. Here, okmarts.com reminds consumers to pay attention to the "four look" when buying air conditioners.

　　Look at scale credibility. Go to a large home appliance store to buy air conditioners with reputable brands.

　　Second, look at the price/performance ratio. Pay attention to avoid conceptual confusion, and do not blindly pursue fashion. New products in the air-conditioning market have emerged one after another. There are various health air-conditioning concepts such as photocatalysts, cold catalysts, oxygen bars, negative ions, and nanometers. The various concepts and functions that manufacturers are hyping up are not lacking in moisture. Consumers should comprehensively consider the price-performance ratio of products when purchasing, and should not blindly pursue fashion.

　　 Three look at performance signs. Pay attention to the three major performance indicators and two certification marks. Three performance indicators: one is the cooling capacity, which is an important basis for consumers to purchase air conditioner products. If the cooling capacity is too small, the predetermined cooling effect cannot be achieved; if the cooling capacity is too large, it will cause a waste of resources. The second is the energy efficiency ratio, which refers to the ratio of the cooling capacity to the effective input power when the air conditioner is in cooling operation. The magnitude of this value reflects the energy saving of air conditioner products. The larger the value of the energy efficiency ratio, the smaller the electric power that needs to be consumed, and the lower the power consumption. The third is noise. The noise generated when the air conditioner is running and excessive noise will seriously affect the lives of consumers. At present, there are two compulsory certification marks for air-conditioning products: one is the "3C mark"; the other is the "energy efficiency mark", which contains five levels of energy efficiency ratio, with z* high as one level and five z* low. When purchasing air conditioners, consumers should focus on these two signs and not be dominated by other certifications.

　　Four watch three packs early rights protection. The air conditioner is a three-guarantee product prescribed by the state. The three-guarantee for the whole machine is valid for one year, and the three-guarantee for the main components (including compressor, fan motor, and thermostat) is valid for three years. Air conditioner performance failure during the warranty period can be repaired, replaced, and returned according to the "Regulations on Responsibility for Repair, Replacement and Return of Certain Products". Consumers who have suffered damages to their legitimate rights and interests as a result of purchasing and using air-conditioning products must provide relevant evidence to choose a way to protect their rights in a timely manner to protect their legitimate rights and interests as early as possible.

　　 Use air conditioning in summer to prevent safety hazards

　　 Continuous high temperature weather has greatly increased the frequency of air conditioning. When people enjoy the coolness brought by air-conditioning indoors, in addition to worrying about the common "air-conditioning disease", they should also beware of hidden safety hazards brought by air-conditioning. Here, I would like to remind consumers that they must keep in mind the safe use and do not care about:

　　 1. The installation must be standardized. After purchasing the air conditioner, be sure to ask a professional installer to install it. Don't be greedy for convenience, just ask someone to install it. Avoid improper installation and even cause a fire.

　　 2. Use switches and plugs correctly. Switches must be used to start and stop the air conditioner, and do not directly plug in or unplug the power plug to turn on or stop the air conditioner. Otherwise, it will cause damage to the air conditioning control system, and cause an electric arc between the plug and the socket when plugging or unplugging, causing personal safety accidents. And long-term standby, not only consumes a certain amount of power, but also easily be struck by lightning in a thunderstorm. When not in use for a long time, please cut off the power supply. The plug must be inserted tightly and cannot be loosened, otherwise it will cause poor contact and damage the air conditioner. In addition, do not place easily combustible objects under the installed air conditioner. Once the air conditioner circuit fails, unnecessary losses can also be avoided.

　　 3. Set up dedicated lines. The power supply of the air conditioner should have a dedicated line, and a circuit breaker or air switch should be installed in the dedicated line. The power supply wires and fuses should comply with relevant regulations and cannot be changed at will. z*Set up the leakage protector, its operating current is 15-30 mA, and the cut-off time should not be more than 0.1 second.

　　4. Read the instruction manual carefully, operate according to the regulations, and don't press the remote control indiscriminately. There should be 3 to 5 minutes between two starts.

　　 5. Once an abnormal sound occurs, immediately shut down, cut off the power supply, and ask the manufacturer's special maintenance point or office technician to come to the site for inspection. When the power supply voltage exceeds the working rated voltage, the air conditioner must be disabled to ensure safety. When using the air conditioner, if the power supply voltage is found to be too low, immediately power off and stop using it to avoid damage to the compressor.

　　 6. When the air conditioner is running, do not spray insecticides or volatile liquids on it to avoid leakage of electricity and cause a fire.

　　 Air conditioning consumption tips

　　 What does the power standard of 1 horse, 1.5 horse and 2 horses mean?

　　 "Hit" is the power unit, which refers to the input power. 1 horse (metric) = 1 horsepower (HP) = 0.735kW (kilowatt) = 735W.

　　 It is generally customary to use 1 horse with a cooling capacity equivalent to 2500W, and the power consumption is 700-800W and so on.

According to this situation, the horsepower and cooling capacity of the air conditioner can be roughly judged. The cooling capacity of an air conditioner of 1 horsepower is about 2500W. Under normal circumstances, 2000W-2700W can be called 1 horse in general, and 2000-2300W is called Small one, 2300-2500W is called one horse, 2500-2700W is called big one; 3200W-3600W can be called 1.5 horses; 4500W-5100W can be called 2 horses.

Except for special occasions, generally speaking, a room with an area of ​​about 10 square meters can meet the demand by purchasing a wall-mounted air conditioner with a power of 1 HP; for a room with an area of ​​about 15 square meters, you can choose a smaller one and a half power. Wall-mounted air conditioner with an area of ​​about 20 square meters, you can choose a wall-mounted air conditioner with 1.5 horsepower or 2 horsepower or a floor-standing air conditioner with 2 horsepower; for more than 20 square meters, you can choose the corresponding power size according to the actual room size Floor-standing air conditioner.
