When consumers buy air conditioners, in addition to fundamental temperature adjustment, some people pay attention to products attached to the health concept and function. Today, there are many products claimed to have health features such as clean, sterilization, new wind, purification. What is the function of these products? Not long ago, the Chinese Consumer Association, the Hebei Consumer Rights Protection Committee and the Shenyang Consumers Association jointly launched a comparison test of healthy air conditioning.
The 15 samples of this comparative trial are Wall-mounted air conditioners involving 13 brands, and the purchase price ranges from 2000 to 8,000 yuan. In 15 air conditioning samples, 14 claims have self-cleaning functions, 11 claimed with "wind avers", etc., in addition, there is an air-conditioning product claimed to have functions such as sterilization, air purification, new wind.
Air conditioning self-cleaning features can better clean the air-conditioner that is not easy to wipe. The self-cleaning function is usually used to reduce the temperature of the evaporator, so that the evaporator surface is condensed into a cream, and then at the temperature regulation, with the melting of the frost and the surface of the evaporator and dust. 14 samples claimed to have self-cleaning function, and the test found that 11 can be achieved from clean bacteria and self-cleaning dust, and some brand samples cannot operate at the start of the cleaning function, and can not produce condensed water, and cannot achieve condensation Water is self-cleaning the dust.
Among the 15 samples, 4 declared that they have purified air. Comparative test Test its particulate clean air output ratio (CADR) indicator, the higher the CADR value, the stronger the purification ability of the particulate matter. The four air conditioner samples were measured at a maximum of 247.3 cubic meters per hour, with a minimum of 130.1 cubic meters per hour. Then, for 50 cubic meters of space (about 20 square meters of room), purifying indoor air, the longest time consumption in the sample is about 23 minutes, the shortest consumption of about 12 minutes.
Whether air-conditioning blows is comfortable, it is a common concern for consumers. From the perspective, the temperature uniformity of the 14 air conditioning prototypes, the temperature difference, and the temperature fluctuations are better, but the blowpacity gap is large. The highest blow is 5.00, the lowest score is 1.82.
This trial found that some air conditioning samples are too simple, especially how it is too simple, which is too simple to use, which is not conducive to consumers. For example, self-cleaning function, the specification does not specifically explain that it is self-cleaning bacteria or dust, which is easy to misunderstand consumers, affecting the use of products.
The relevant person in charge of China Consumers Association said it is recommended that the industry associations and standard competent authorities will promote the health function of air conditioning products. It is recommended that consumers should choose to purchase according to their actual needs, and pay attention to whether there is data and formal test report support according to their actual needs.
