Introduction: Humidity - the eternal enemy of mankind

From the moisture-proof design of ancient Egyptian pyramids to the environmental control of modern data centres, mankind's fight against humidity has lasted for thousands of years. In the industrial sector, high humidity can lead to a range of serious problems such as metal corrosion, electronic equipment failure, and pharmaceutical deterioration. This article takes explores the surprising evolution of industrial dehumidification technology from primitive methods to modern technology.

Chapter 1: Ancient Wisdom - Primitive Dehumidification Techniques

1.1 Physical adsorption method (3000 BC)

Charcoal fire dehumidification: the ancients burned charcoal in a confined space, using the adsorption of charcoal to absorb moisture

Lime moisture: the Romans used quicklime as a moisture barrier in their buildings

Salt dehumidification: medieval Europe used rock salt to absorb moisture in cellars

1.2 Passive ventilation design

The overhead structure of the ancient Chinese ‘dry-structure’.

Ventilation shaft systems in European castle design

Natural dehumidification in Persian ‘wind towers

Chapter 2: Technological leaps brought about by the Industrial Revolution (18th-19th centuries)

2.1 The Age of Mechanical Ventilation

Steam-engine-driven forced ventilation systems

The first dehumidification needs of textile factories (the case of the Manchester Cotton Mill in 1850)

Simple rotor dehumidifiers used in basements

2.2 Breakthroughs in Refrigeration Technology

1851 First commercial ice machine introduced

1902 Willis Carrier invented modern air conditioner

1911 Establishment of enthalpy and humidity diagram theory

AI optimisation: deep learning to predict humidity changes

Miniaturisation: chip-scale dehumidification device under development

5.2 Industry Challenges

Extreme environment adaptation (e.g. deep sea oil platforms)

Higher energy efficiency standards (new EU 2027 regulation)

Dehumidification of special gas environments (semiconductor factories)

Conclusion: From passive defence to active control

From the ancients burning charcoal to dehumidify to today's intelligent industrial dehumidification system, the history of mankind's fight against humidity is a history of technological innovation. Modern industrial dehumidifier not only solves the production environment control problems, but also provides key protection for precision manufacturing, medicine and health, food preservation and other industries. In the future, with the development of new materials and AI technology, industrial dehumidification technology will usher in a new breakthrough.
