Some operators have shared with reporters that after testing certain ventilation technologies, they haven't achieved energy savings of over 50%, as promoted. In reality, all energy-saving technologies come with their own advantages and limitations, and they are also subject to environmental conditions. No single solution works for every situation—each case needs a tailored approach. Currently, there are numerous energy-saving products available for base stations, and the number of manufacturers is growing. The data on energy efficiency vary significantly across different technologies. Seven types of base stations have been equipped with energy-saving solutions, and each has been analyzed and evaluated based on its performance.
1. New Energy Efficiency: 30%
When it comes to new energy applications, optoelectronic complementarity has become one of the most popular technologies in base station operations. This technology emerged in response to global energy shortages and climate change in the 21st century. It works by converting solar energy into electricity through a photovoltaic system, while still using traditional power sources like main power or diesel generators. This combination allows for more efficient energy use, reduces consumption, and ensures stable system operation. The technology is currently being implemented in energy-rich regions such as Inner Mongolia and Tibet.
Applicable Environment: Areas with high solar exposure, such as Inner Mongolia and Qinghai.
Advantages: Using renewable energy can significantly reduce carbon emissions, even achieving near-zero emissions.
Disadvantages: The technology is limited by natural conditions, only suitable for places with abundant sunlight. Additionally, the production of solar panels causes serious environmental pollution.
Rating: ★★★☆☆
2. Intelligent Ventilation Energy Efficiency: 20% - 70%
Intelligent ventilation technology takes advantage of outdoor cold air when the outside temperature is lower than inside. By introducing this cold air into the equipment room, heat is removed, reducing the need for air conditioning and saving energy. There are three main methods for utilizing outdoor cold sources: direct fresh air systems, heat recovery ventilators, and glycol dry heat exchangers.
Applicable Environment: Places with large temperature differences and not too hot climates. Can be used alongside air conditioners but should avoid dusty areas like power plants.
Advantages: Offers the highest energy savings among the listed technologies.
Disadvantages: If the temperature difference is small, the energy-saving effect is minimal. Dusty environments can affect performance due to filters needing frequent replacement, increasing maintenance workload.
Rating: ★★★★☆
3. Energy-Saving Air Conditioner Efficiency: 30%-50%
Energy-saving air conditioners are a broad category, but most modern ones combine variable frequency technology or intelligent ventilation. Inverter air conditioners feature a frequency-controlled compressor that adjusts cooling output based on room conditions, ensuring consistent temperature without constant operation. This leads to improved efficiency and better stability in base station environments.
Applicable Environment: Best in areas where traffic volume changes periodically. When using fresh air, attention should be paid to surrounding dust levels.
Advantages: Compared to traditional air conditioners, energy-saving models offer better efficiency and safety for base station operations.
Disadvantages: While efficient at partial loads, inverter air conditioners lose their advantage at full or very low loads. They are also more expensive than standard models, often costing over 10,000 yuan.
Rating: ★★★★☆
4. Battery Cabinet Energy Efficiency: Varies by Temperature Range
Battery cabinets are small enclosures designed to protect batteries from extreme temperatures, which helps maintain room temperature and reduce reliance on air conditioning. Since batteries are sensitive to heat, maintaining an optimal environment is crucial for their longevity, even if other equipment can tolerate higher temperatures.
Applicable Environment: Suitable for most locations, though not recommended for critical base stations or those with minimal air conditioning use.
Advantages: Helps raise room temperature, reducing air conditioning usage and saving energy.
Disadvantages: While no major drawbacks exist, avoiding air conditioning in some cases may slightly impact the lifespan of main equipment, though the risk remains manageable.
Rating: ★★★★★
5. Integrated Container Room Efficiency: 50%
An integrated container room is a modular, pre-fabricated structure designed to house base station equipment. Unlike traditional brick-and-mortar rooms, these units are built with specialized materials, making them easy to assemble and disassemble. They provide a standardized, efficient environment for base station operations.
Key Features: Standardized design, quick deployment, multiple installation options, and cost-effective construction. These rooms are highly integrated, allowing for flexible scaling and reduced CAPEX.
Applicable Environment: No specific environmental requirements needed.
Advantages: Improves integration, reduces costs, speeds up deployment, and offers good performance at a low price.
Disadvantages: Its ability to withstand extreme weather events like hurricanes or earthquakes still needs real-world validation.
Rating: ★★★★
6. DCS Technology Efficiency: 30%
Object-Oriented Cooling (O2C) is an innovative cooling method developed by Zhejiang University and Zhongcheng Technology. It's an all-weather, intelligent, distributed mobile base station cooling system. Based on the number of heating devices, it installs corresponding indoor evaporators connected in parallel or series to an outdoor unit, forming a mini central air conditioning system. This system integrates two circulation loops, one for refrigerant and another for water, controlled by compressors and pumps to optimize energy use based on seasonal and environmental conditions.
Applicable Environment: No special environmental requirements.
Advantages: Provides targeted cooling by adjusting air supply based on outlet temperature, improving energy efficiency.
Disadvantages: Installation near main equipment complicates maintenance. Precise temperature control may affect call drop rates.
Rating: ★★★★☆
7. Passive Energy-Saving Technology Efficiency: Over 20%
Passive energy-saving technology improves the thermal performance of building envelopes and base station equipment. This allows internal heat generated by equipment to be efficiently dissipated, maintaining a stable and energy-efficient environment.
Applicable Environment: Areas with minimal temperature fluctuations, such as the Northeast, are ideal for this technology.
Advantages: Reduces energy use and approaches zero emissions.
Disadvantages: Summer and winter require different heat transfer coefficients, making it challenging to balance. Also, structural modifications are difficult in rented or self-built buildings.
Rating: ★★★★☆
Oca Sheet
OCA (Optically Clear Adhesive) glue sheet is a type of adhesive film that is used in the assembly of electronic devices, particularly in the display industry. It is a transparent and optically clear adhesive that is used to bond different layers of a display module together. OCA glue sheets are commonly used in the manufacturing of smartphones, tablets, and other electronic devices with touch screens or LCD displays.
The main purpose of OCA glue sheets is to provide a strong and reliable bond between the layers of a display module, while also ensuring optical clarity and minimal distortion. It helps to eliminate air gaps and improve the overall visual quality of the display by reducing reflections and enhancing color vibrancy.
OCA glue sheets are typically made of a high-quality acrylic material that is optically transparent. They are available in various thicknesses and sizes to suit different display applications. The sheets are usually pre-cut to the required dimensions and then applied to the display layers using a lamination process.
Overall, OCA glue sheets play a crucial role in the manufacturing of electronic devices with displays, providing a reliable and visually pleasing bonding solution.
