With the progress of technology and the continuous update of product technology, such as pharmaceutical, electronics, semiconductors, food and other industries, the production process and production process of rotary dehumidifier units on the environmental temperature, humidity, cleanliness requirements are high, we need to provide a more effective and relatively low energy consumption of air conditioning system, especially for low humidity environment air conditioning needs.

At present, air dehumidification is mainly cooling dehumidification, rotary dehumidification, in the air conditioning dehumidification system, cooling dehumidification and rotary dehumidification are the main means, cooling dehumidification is not very high in the environment (bandaging 60 ~ 65% RH), the effect is still relatively good, and stable performance and energy consumption is relatively low, and it is widely used.

But in the production environment, the humidity requirements are high (RH = 45±5%), cooling dehumidification is obviously not economical, rotary dryer, it will not be affected by the air dew point, the water is very large, especially for low humidity conditions, but if all the rotor dehumidifier dehumidification only, the amount of renewable energy is also large, this type of program is not economical.

Because wheel dehumidification and cooling dehumidification have advantages and disadvantages, after combination optimization, the length is complementary, and the complementarity is shorter, and the effect will be better played.

Wheels and cooling combined dehumidification air conditioning system combined with cooling dehumidification circulation system and wheel split, heat and heat exchange used heat absorption dehumidification refrigeration system dehumidification, dehumidification, Rotary removal machine, cooling dehumidification in a certain range of good, stable performance, but when the humidity requirements are low, the ability of cooling dehumidification significantly decreased.

At this time, the hub and cooling joint dehumidification system can achieve good results, cooling dehumidification unit, emphasizing the characteristics of low energy consumption under the conditions of Roth fresh air high dew point dehumidifier, the use of wheel dehumidification denied wet, highlighting the low temperature and low temperature and low temperature conditions of the wheel, not limited by dew point and removal rate.

The system commonly used processing flow is as follows :1: cooling dehumidification; 2: Rover dehumidification; 3: wet cooling; 4: regenerative heating; 5: Adiabatic regeneration

In the low humidity environment, the dehumidification air conditioning system with the combination of flow channel and cooling has the advantage of the dehumidifier only cooling uncomfortable.
