Based on the basic performance of ordinary air conditioners, it adds many health functions, including self-cleaning, sterilization, fresh air, purification and comfort.
Blowing sensation index
It is to measure the percentage of people who are dissatisfied with the air conditioning blowing. A large blowing sensation index indicates that the wind speed is high, and the greater the percentage of people who are dissatisfied with this blowing sensation.
Different "healthy air conditioners" have different comfort levels.
In this experiment, as ordinary consumers, the staff of City Consumers Association randomly purchased 15 "healthy air conditioners" from e-commerce platforms such as JD.COM and Gome.
Whether the air blown by air conditioners is comfortable or not is a common concern of consumers. The staff selected the 14 model in the sample car for comfort evaluation. After a certain space is started, the comfort of air conditioning is tested by four data: temperature uniformity, vertical temperature difference, temperature fluctuation and blowing sensation index. From the results, the temperature uniformity, vertical temperature difference and temperature fluctuation of the tested air conditioner prototype all perform well, but the blowing feeling is quite different. In 14 samples, the highest blowing sensation score is 5.00, and the lowest is 1.82. On the whole, there is a certain gap in the comfort of the tested sample car.
Replace the filter regularly to avoid secondary pollution.
Removing bacteria from indoor air is the selling point of many air-conditioning products. In the staff comparison test, five air-conditioning prototypes claiming sterilization function were selected to test the sterilization rate. The highest sterilization rate is 99.6% and the lowest is 98.3%, and the sterilization effect is satisfactory.
City Consumers Association staff reminded consumers that the key components of some air conditioners with purification function are filter screens or IFD electrostatic precipitator modules, which must be replaced or cleaned regularly during use, otherwise they will become indoor air pollution sources and produce secondary pollution. It is understood that the service life of different filter elements is different, generally 1-2 months. Different environmental pollution has different service life of filter screen.
Buy a "healthy air conditioner", first look at self-cleaning and comfort.
According to the staff of the Municipal Consumers Association, according to the results of this comparative test, when consumers buy healthy air conditioners, it is recommended to give priority to products that claim to have self-cleaning function and comfort function. In addition, additional fresh air or purification functions can be considered.
When purchasing "healthy air conditioners", products without product name information, brand model and health function description should be avoided. At the same time, we should pay attention to whether the related functions of business promotion are supported by data and formal test reports.
Pay attention to after-sales service and use cost. For example, the filter screen of air conditioning purification function is a continuous investment, and the replacement cost of the filter screen should be considered when purchasing. You should also know the installation, the warranty period of the whole machine and how to clean it.
