Five indicators, check the humidification engineering technology is not high?

　　First, humidification capacity

　　This is the most important parameter of humidification engineering, some enterprises in order to cater to consumers in the pursuit of greater humidity, at will mark the greater humidity, so the standard strictly stipulates that the humidification capacity should not be lower than the nominal value of the rated humidification capacity of the product.

　　Two, for many humidifiers with softening water, humidity display and other auxiliary functions

　　In order to prevent some products clearly do not have this function, or this function can not play the corresponding effect, and through the means of false propaganda to mislead consumers, the standard on these auxiliary functions also put forward specific requirements: for water softener, the standard stipulates after the softener softening, the hardness of water should not exceed 100mg/L. Water softener before failure, the total amount of water softened should not be less than 100L. As for the humidity display, it is stipulated that the error of the humidity display should be within ±10% within the range of 30% ~ 70% relative humidity, so as not to mislead consumers if the error is too large. 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 making the humidifier in a long-term low-performance and low-efficiency working state without their knowledge.

　　Three, evaporation core (device) service life

　　For the direct evaporative industrial humidifier, the evaporative core (evaporator) is the component that has the greatest influence on the performance. With the continuous use of humidification, the efficiency of the evaporation core (device) will continue to decrease, and the humidification volume will also continue to decline. The standard stipulates that when the humidification capacity is reduced to 50% of the initial humidification capacity, the evaporation core is deemed to fail. For the replaceable evaporating core (device), its service life should not be less than 1000 hours.

　　Four, humidification efficiency

　　It is the ratio of the actual humidifier capacity to the input power. It reflects the amount of humidification capacity that can be generated per unit power consumption. It is an important indicator to measure the humidification performance. In order to guide consumers to buy energy-saving and environmentally friendly products and promote enterprises to develop more efficient products, the standard classifies the index into four grades: A, B, C and D.

　　Five, the noise

　　Considering that the humidification project may be used in the bedroom, if the noise is too large, it will have a certain impact on consumers, so the standard is strictly limited to the noise index.
