Performance standards of Electric Heating Humidifier
The first is the amount of humidification. This is the most important parameter of the humidifier. Some companies will arbitrarily mark the amount of humidification to meet the consumer's pursuit of a large amount of humidification. Therefore, the standard strictly stipulates that the amount of humidification should not be lower than the nominal value of the rated humidification amount of the product.
The second is humidification efficiency. Refers to the ratio of the actual humidification amount of the humidifier to the input power, which reflects how much humidification amount can be generated by the unit power consumption. It is an important indicator to measure the performance of the humidifier. In order to guide consumers to purchase energy-saving and environmentally-friendly products, and to promote various enterprises to develop more efficient products, the standard divides this indicator into four levels: A, B, C, and D.
The third is noise. Considering that the humidifier may be used in the bedroom, if the noise is too large, it will have a certain impact on consumers, so the standard has strict limits on noise indicators.
The fourth is the service life of the evaporation core. For direct evaporative humidifiers, the evaporating core is the component that has the greatest impact on performance. With the continuous use of the humidifier, the efficiency of the evaporation core (device) will continue to decrease, and the amount of humidification will also continue to decline. The standard stipulates that when the humidification amount of the humidifier is reduced to 50% of the initial humidification amount, the evaporation core is deemed to have failed. For the replaceable evaporation core (device), its service life should not be less than 1000 hours.
Fifth, for many humidifiers with auxiliary functions such as softened water and humidity display, in order to prevent certain products from not having this function, or this function cannot achieve the corresponding effect, and misleading consumers through false publicity, The standard also puts forward specific requirements for these auxiliary functions: For water softeners, the standard stipulates that after the softener is softened, the hardness of the water should not exceed 100 mg / L. Before the water softener fails, the total amount of softened water should not be less than 100L. As for the humidity display, it is stipulated that the relative humidity is within the range of 30% to 70%, and the error of the humidity display should be within ± 10%, so as not to cause too much error and lead to misleading consumers. In addition, the standard also stipulates that because the water level will have a significant impact on the performance of some humidifiers, the humidifier should have a water level protection function to prevent consumers from unwittingly leaving the humidifier in a low-performance, low-efficiency environment for a long time.
