Do desiccant wheels really work?

1. What is desiccant wheel technology?

In the dehumidifier, the dehumidification wheel is indispensable, and the desiccant wheels can also be called the heat recovery wheel. By reducing the air temperature below the dew point and allowing moisture to condense on the fins of the indoor coil to remove humidity desiccant moisture from the air, a typical complete air conditioning system is formed.

2. Look like

What does the desiccant wheel look like? Technically speaking, the desiccant wheel is basically a circular plastic or styrene disc with an extended surface impregnated with silica gel. The silica gel is placed in a small white bag that is installed in the camera and electronic equipment to absorb any moisture that enters the box, and then it can remove the moisture in the air and achieve the effect of dehumidification.

 

3. Do desiccant wheels really work?

How does the desiccant heat wheel work in the desiccant dehumidifier? The most obvious place to work is where a large amount of clean, extremely humid outdoor air must be treated. Schools, large boxes, retail, warehouse-style shops are the best choices for desiccant dehumidification wheels. In this case, use one or two 40-ton packaged roof units with heat recovery silica gel desiccant wheels for complete ventilation. Or you can order additional roof installations without any outdoor air options, which is the best way to deal with it. The heat recovery wheel will definitely reduce the overall installation tonnage and electrical service requirements, and provide dehumidification of the ventilation air.

 

Of course, the drying hot wheel also has its own shortcomings. One of the shortcomings is that the initial cost and space requirements of the equipment containing household desiccant have increased. Because the motor that rotates the wheel and the increased resistance of the wheel and filter to the air passing through the wheel consume energy, more costs are incurred, and there is also the maintenance desiccant wheel cost, because the drying hot wheel usually requires additional filtration. Furthermore, the desiccant heat recovery wheel must be kept clean at all times, so whenever you use it, the seal that separates the wheel into the exhaust part and the outdoor air part must be kept in good condition. You are also required to check and clean every month. Heat recovery wheel.

 

What is the best strategy for handling ventilation air? The first is to start with a team composed of your designers, mechanical engineers and service companies. You need to discuss the plan, explore the prototype and consider how to introduce how much outdoor air, how much air to heat and cool, and how to use resources. Finally, develop strategies to reduce the amount of heating and cooling air.
