Against the backdrop of global climate change, low-carbon living has become a 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 It is not only related to the comfort and health of residents but also an indispensable process in various industries and a key link in achieving low-carbon goals. Intelligent Humidity Management System have emerged, providing innovative solutions for environmental humidity adjustment with their high efficiency and energy saving characteristics. This article will briefly introduce the relevant technologies and discuss how they can promote the improvement of low-carbon efficiency, in order to contribute to sustainable development.

How Humidity Control Reduces Emissions

In the current field of humidity control and humidity management, there are mainly two management strategies: passive control and active control. A representative of passive control is desiccant packs, which Desiccants are widely used in the packaging of textiles, food, and pharmaceuticals. Their components usually include calcium chloride, calcium sulfate, silica gel, and activated alumina, etc., to absorb excess moisture from the environment. Active control, on the other hand, relies on equipment such as air conditioners, humidifiers, and dehumidifiers to dynamically adjust and maintain the humidity balance of the environment. Desiccants Packs are usually made of plastic and fabric filling, while power equipment needs to run continuously to ensure the stability of environmental humidity. However, these two traditional humidity control methods have certain limitations; they often find it difficult 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 the cost but is also not environmentally friendly. In active control, the continuous operation of the equipment consumes a large amount of energy, and there may be energy waste during the adjustment process.

Low-Carbon Efficiency of Humidity Control Systems

Recently, commissioned by Shanghai Hengyuan Polymer Materials Co., Ltd., Shanghai Yitan completed the carbon footprint calculation of its fiber desiccant products and the assessment of the carbon reduction capacity of its power control humidity management system. It was found that when the functional unit is set to the same drying effect, Fiber Desiccants compared to traditional silica gel desiccants, the product carbon footprint has been reduced by about 300% Hengyuan's fiber desiccant uses a small amount of calcium chloride solution and combines wood fiber materials for molecular structure design, while the outer packaging uses biodegradable material PLA. When calculating the carbon footprint of PLA packaging, the relevant descriptions of the national standard "GB/T 41638.1-2022 Carbon Footprint and Environmental Footprint of Bio-based Plastics Part 1: General Rules" were referenced. Because plants remove and store atmospheric carbon during photosynthesis, products made from 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 can also be integrated with the product packaging to reduce direct contact with the product, ensuring safety and pollution-free.

For the assessment of the carbon reduction capacity of the power control humidity management system, we collected the use of new constant temperature and humidity air conditioners at home and abroad. In a 300-square-meter warehouse with a cleanliness level of 10000, a temperature setting of 23℃, a humidity setting of 55%, and 24-hour operation, the new constant temperature and humidity air conditioner can reduce electricity consumption by about 40% compared to the traditional air conditioner + electric heater + humidifier dehumidification system, with an actual reduction in electricity consumption of 544123 kWh, equivalent to a reduction of more than 300 tons of carbon dioxide equivalent.

Hengyuan's intelligent humidity management system, by fully utilizing the mass transfer capacity of air, supplemented by an in-space sensing system and new mineral humidity-regulating board materials, has been calculated to reduce energy consumption in the workshop compared to traditional power equipment by a further 50% significantly improving energy utilization efficiency and enhancing the company's carbon reduction capabilities.

The following figure shows a control experiment in an art warehouse. In this experiment, using mineral humidity-regulating boards in combination with existing power equipment, while maintaining relatively constant humidity, compared to traditional pure power equipment workshops, energy consumption was reduced by 80% In a 400-square-meter electronic equipment warehouse, Hengyuan also conducted a similar experiment. Combining its unique fiber humidity-regulating materials, compared to the traditional air conditioner + electric heater + humidifier + dehumidifier system, it can achieve an 80% reduction in energy consumption in winter and a 30% reduction in energy consumption in spring.

Based on its deep accumulation in the field of humidity regulation, Hengyuan has opened up a new development path in the innovation and improvement of product processes. Its Fiber Desiccants products need to go through key steps such as liquid preparation, drying, sheet making, and packaging during the production process, among which the drying process is particularly energy-intensive. Hengyuan, with its deep insight into mass transfer models and material properties, combined with the sensitive response of fiber desiccants to environmental temperature and humidity during the drying process, uses the interconnection of intelligent terminals and power systems, and precise control of key parameters such as wind speed, temperature, and humidity through algorithms to revolutionize the traditional drying process. This innovative measure, while maintaining output, has successfully reduced energy consumption by about 50%, equivalent to a reduction of 100 tons of carbon dioxide equivalent emissions per year. Hengyuan Company is developing optimized drying system solutions for different industries and enterprises based on its current humidity control model and algorithm capabilities, continuing to contribute to green manufacturing.

Broad Application Scenarios

Hengyuan Company's humidity control model allows its products to handle various humidity conditions with ease. The model-based intelligent algorithm, combined with a humidity management system using temperature and humidity sensors, enables various enterprises to achieve the most efficient humidity management system at the lowest cost. In the future, more industries and enterprises will require such integrated temperature and humidity management systems to ensure improved production efficiency, product quality, and energy saving and carbon reduction efficiency. Hengyuan's applications are extensive, ranging from clothing moisture-proofing to intelligent driving safety and energy consumption reduction in new energy vehicles, from constant humidity drying in food and pharmaceutical production to moisture control applications in building materials. Hengyuan Company's products have broad application prospects. We look forward to more and more companies bringing low-carbon materials and carbon reduction technologies to jointly address climate change. This requires macro-management from enterprises, industries, and the country, as well as new technologies and capabilities that start with small details and achieve significant results, to address climate change and achieve the sustainable development goals of enterprises and the industrial chain.
