During seasons of fluctuating humidity, we yearn to banish the sticky discomfort of rainy seasons while also seeking relief from 

winter dryness. Have you ever imagined how wonderful it would be to have a machine—like a thoughtful butler—automatically 

maintaining just the right humidity for us? Today, this is no longer a fantasy. So, how does this machine master the seemingly 

contradictory skills of “absorbing water” and “releasing water” simultaneously? The secret lies in an ingenious “two-in-one” system.

Core “Duet”: Compressor Refrigeration and Cold Evaporation

Inside this machine, a seamless “duet” unfolds, featuring two protagonists: the “dehumidification expert”—the compressor 

refrigeration system—and the “humidification specialist”—the cold evaporation system.

• The “Water-Absorbing” Magic: Compressor Refrigeration Dehumidification

  Its operating principle mirrors that of air conditioner refrigeration. When dehumidification is needed, the core component—the 

  compressor—kicks in, driving a special refrigerant through sealed pipes. First, the refrigerant flows through an “evaporator,”

  which acts like ice to absorb heat from the passing air. This rapidly cools the evaporator's fins to a temperature far below

  the room air's dew point.

  When humid air is drawn into the machine by a fan and passes over the chilled evaporator, the water vapor instantly cools

  and condenses into tiny droplets. These droplets adhere to the fins and eventually collect in a water reservoir or drain out

  through a pipe. This completes the “water absorption” process. Simultaneously, the cooled and dried air passes through

  another component called the “condenser” (a section heated by the compressor) to undergo moderate reheating. This

  prevents the machine from blowing uncomfortably cold air.

• The Art of “Water Release”: Cold Evaporative Humidification

  When environmental humidification is required, the machine switches to an entirely different operating principle. Cold

  evaporative technology, as the name suggests, relies on natural evaporation of water at room temperature. Inside the unit,

  a highly absorbent evaporative mesh (or evaporative filter) is engineered with an extensive surface area. A precise water

  distribution system evenly saturates this mesh with moisture.

  Simultaneously, a separate fan draws dry air across the damp evaporative mesh. Under the influence of this airflow, water

  evaporates rapidly and quietly into the surrounding air, uniformly and naturally increasing ambient humidity. This process 

  resembles air-drying wet clothes but operates with greater efficiency and controllability. Since no heating is involved, it

  produces no white residue and eliminates scalding risks, ensuring enhanced safety and health.

Intelligent Core: Smart Sensing and Seamless Switching

The true “intelligent core” enabling a machine to effortlessly switch between two opposing modes is its smart sensing system.

High-precision humidity sensors inside the unit act as tireless “environmental scouts,” constantly monitoring surrounding air 

humidity. This data is transmitted in real-time to the central processing chip.

The user-set target humidity serves as the chip's “action plan.” The chip compares the real-time humidity reported by the 

sensors against the target value and makes precise decisions:

• When real-time humidity > target humidity, dehumidification will be activated.

• When real-time humidity < target humidity, humidification will be activated.

This intelligent switching occurs completely automatically and silently, ensuring the indoor environment is always maintained 

within the user-set comfortable humidity range, achieving true “moisture balance.”

Conclusion

Thus, a machine capable of both “water absorption” and “water expulsion” does not rely on contradictory magic. Instead, 

it cleverly integrates two mature physical technologies—compression refrigeration and cold evaporation—within a single unit. 

An intelligent sensing system acts as the command center, precisely coordinating operations based on environmental demands. 

This represents the future of modern home appliances: no longer single-function tools, but intelligent living companions integrating 

multiple technologies with environmental awareness and decision-making capabilities, quietly safeguarding our comfortable lives.
