In the context of global climate change, low-carbon living has become our shared green dream. As a major source of energy consumption and greenhouse gas emissions, the low-carbon transformation of the industrial sector is particularly urgent. Humidity Control not only concerns the comfort and health of residents but is also an essential process across various industries, and a crucial link in achieving low-carbon goals. With the rapid development of technology, new constant humidity materials and intelligent humidity management systems have emerged, offering innovative solutions for environmental humidity regulation with their high efficiency and energy-saving characteristics. This article will briefly introduce relevant technologies and discuss how they promote the enhancement of low-carbon performance, hoping to contribute a small part to sustainable development. 

How Humidity Control Reduces Emissions 

Humidity Control is an indispensable part of building environment management, and also a critical link in the manufacturing process of cutting-edge electronic equipment. Humidity control plays a pivotal role in ensuring human health, extending building lifespan, preventing corrosion of metals and cultural relics, and preventing spoilage of food and medicine. For China's booming information industry and chip manufacturing sector, the importance of humidity management is becoming increasingly prominent. For instance, communication base stations reduce energy consumption by controlling equipment power on/off, thereby lowering carbon emissions. However, temperature differences generated during equipment shutdown can lead to condensation, which can damage the equipment. Therefore, stabilizing humidity within base stations becomes key to controlling carbon emissions. For the chip industry, appropriate humidity can reduce static electricity generation, protecting chips from damage. Chip manufacturing involves numerous chemical processes such as lithography, etching, and cleaning, and humidity fluctuations will directly affect the efficiency and results of these processes, thereby impacting chip performance and quality. Therefore, implementing precise humidity control strategies is of great significance for promoting low-carbon sustainable development, ensuring product quality, and improving production efficiency. 

In the current field of humidity control and management, there are two main strategies: passive control and active control. Passive control is represented by desiccant packs, which are a type of desiccant widely used in the packaging of textiles, food, and pharmaceuticals. Their components typically include calcium chloride, calcium sulfate, silica gel, and activated alumina, which absorb excess moisture from the environment. Active control, on the other hand, relies on equipment such as air conditioners, humidifiers, and dehumidifiers, maintaining environmental humidity balance through dynamic regulation. desiccant packs are usually filled with plastic and fabric, while active equipment requires continuous operation to ensure stable environmental humidity. However, these two traditional humidity control methods have certain limitations; they often struggle to achieve resource recycling and efficient energy use. In passive control, once the desiccant is saturated with moisture, it needs to be replaced, which not only increases costs but is also detrimental to environmental protection. In active control, the continuous operation of equipment consumes significant energy, and there may be issues of energy waste during the regulation process. 

Low-Carbon Performance of Humidity Control Systems 

Recently, entrusted by Shanghai Hengyuan Polymer Material Co., Ltd., Shanghai Yitan completed the carbon footprint accounting of its fiber desiccant products and the evaluation of the carbon reduction capability of its active humidity control management system. Calculations showed that when the functional unit was set to achieve equivalent drying effects, fiber desiccant reduced the product carbon footprint by approximately compared to traditional silica gel desiccants. 300% Hengyuan's fiber desiccant uses a small amount of calcium chloride solution combined with lignocellulosic materials for molecular structure design, and its outer packaging uses biodegradable material PLA . When calculating the PLA carbon footprint of packaging, reference was made to the national standard GB/T 41638.1-2022 Plastics - Carbon footprint and environmental footprint of biobased plastics - Part 1 : General principles". Bio-based materials, as plants remove and store atmospheric carbon through photosynthesis, products prepared using these raw materials contribute to the continuous establishment of a low-carbon circular economy. Combined with excellent structural design, these materials can not only be used as desiccant packs but also integrated with product outer packaging, reducing direct contact with the product and ensuring safety and pollution-free. 

For the evaluation of the carbon reduction capability of active humidity control management systems, we collected data on the usage of new constant temperature and humidity air conditioners both domestically and internationally. In a 300 square meters, clean class 10000 with temperature set at 23℃ humidity set at 55%、24 -hour operating warehouse, the new constant temperature and humidity air conditioner compared to traditional air conditioners + electric heater + humidifier dehumidification system, can reduce electricity consumption by approximately 40% with an actual reduction in electricity consumption of 544123kWh equivalent to a reduction of over 300 tons of CO2 equivalent. 

Hengyuan's intelligent humidity management system, by fully utilizing the mass transfer capability of air, supplemented by an in-space sensing system and new mineral humidity-regulating panels, has been calculated to further reduce the energy consumption of the entire system by approximately compared to traditional powered equipment workshops, significantly improving energy utilization efficiency and enhancing the company's carbon reduction capability. 50% significantly improving energy utilization efficiency and enhancing the company's carbon reduction capability. 

The figure below shows a control experiment in an art warehouse. In this experiment, using mineral humidity-regulating panels combined with existing active equipment, while maintaining relatively constant humidity, energy consumption was reduced by compared to traditional pure active equipment workshops. 80% . In a 400 square meter electronic equipment warehouse, Hengyuan also conducted a similar experiment. Combining unique fiber humidity-regulating materials, compared to traditional air conditioners + electric heater + humidifiers + dehumidifier systems, it can achieve a reduction in energy consumption of in winter 80% and in spring. 30% energy consumption reduction.

Its fiber desiccant The product manufacturing process involves key steps such as liquid mixing, drying, sheet forming, and packaging, with the drying stage being particularly energy-intensive. Leveraging a deep understanding of mass transfer models and material properties, Hengyuan Company has revolutionized the traditional drying process. This is achieved by integrating the sensitive response of fiber desiccants to ambient temperature and humidity during drying, utilizing the interconnection of smart terminals and power systems, and employing algorithms for precise control of key parameters such as wind speed, temperature, and humidity. This innovation has successfully reduced energy consumption by approximately 50% while maintaining production output, equivalent to a reduction of 100 tons of carbon dioxide equivalent emissions annually. Hengyuan Company, relying on its current humidity control model and algorithm capabilities, is developing optimized drying system solutions for various industries and companies, continuing to contribute to green manufacturing.
