Household central air conditioning is a type of small air conditioning unit widely used in villas, apartments, hotels, homes, and other places. Its comprehensive benefits are commendable. However, traditional household central air conditioning does not have humidity regulation function. In the north, indoor relative humidity is relatively low, especially in spring, autumn, and winter. Indoor heating keeps the relative humidity between 10% -20% RH. Low relative humidity can cause skin dryness, itching, and other serious diseases such as pharyngitis, and can also cause damage to room decoration, such as dry cracking and deformation of wooden furniture, which is more likely to produce annoying static electricity. A relative humidity of around 45-55% RH is usually a suitable standard for humans. Therefore, humidification of household central air conditioning is particularly important.
Based on this objective fact, Shengjie Technology has developed the SHJ series humidifiers specifically designed for household central air conditioning, which have been widely used in many projects. The SHJ series humidifiers are divided into three types according to their different forms, namely wet film vaporization, electric heating, and ultrasonic.

Wet film vaporization (SHJM)
The working principle of the SHJM household central air conditioning humidifier is to introduce a portion of the air heated by the air conditioning coil into the humidification section through a bypass, and use the principle of a wet film humidifier to humidify the air. The humid air is then sent to the return air duct of the air conditioning through the bypass pipeline, thus humidifying the entire space.
