Some operators have reported that after trying various ventilation technologies, they did not achieve energy savings of over 50%, as claimed by the promotion. In reality, all kinds of energy-saving technologies have their own advantages and disadvantages, and they are also dependent on environmental conditions. No single solution works for every situation; each case requires a tailored approach. Currently, there are many energy-saving products available for base stations, with numerous manufacturers offering different solutions. The energy efficiency data vary widely, and it's important to analyze and evaluate the specific characteristics of the seven main types of base stations equipped with energy-saving technologies.
1. New Energy Efficiency: 30%
When it comes to new energy applications, optoelectronic complementarity is currently 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 uses photovoltaic systems to convert solar energy into electricity, while still relying on traditional power sources like main power or diesel generators. This combination helps maximize energy use, reduce consumption, and ensure system stability. It is currently being implemented in regions rich in solar resources such as Inner Mongolia and Tibet.
Applicable environment: Areas with abundant sunlight, such as Inner Mongolia and Qinghai.
Advantages: Reduces carbon emissions significantly, almost achieving zero emissions.
Disadvantages: Limited by natural conditions, only suitable for areas with high solar irradiance. Additionally, the production of solar panels can cause significant environmental pollution.
Rating: ★★★☆☆
2. Intelligent Ventilation Energy Saving: 20% - 70%
Intelligent ventilation technology makes use of outdoor cold air when the outside temperature is lower than the indoor temperature. By introducing this cold air into the equipment room through technical methods, it helps remove heat from the room, reducing the need for air conditioning and thus saving energy. There are three main ways to utilize outdoor cold sources: direct fresh air systems, heat recovery fresh air ventilators, and glycol dry heat exchangers.
Applicable environment: Areas with large temperature differences and not too hot climates. Can be used with air conditioners but should avoid dusty environments like power plants.
Advantages: Offers the highest energy-saving potential.
Disadvantages: Effectiveness depends on external conditions. If the temperature difference is small, the energy savings may not be significant. 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 current market offerings often combine variable frequency technology or intelligent ventilation. Inverter air conditioners feature a frequency conversion compressor and control system that adjusts cooling capacity based on room conditions. When the desired temperature is reached, the unit runs at a constant speed, maintaining stability and reducing downtime.
Applicable environment: Most effective in areas with periodic traffic fluctuations. When using fresh air technology, attention should be paid to dust levels in the surroundings.
Advantages: Not only saves energy but also improves the safety of base station operations compared to traditional air conditioners.
Disadvantages: Inverter air conditioners lose energy-saving benefits during high or very low load conditions. They are also more expensive than fixed-frequency models, with prices typically exceeding 10,000 yuan.
Rating: ★★★★☆
4. Battery Cabinet Energy Saving: Based on Temperature Range
The battery cabinet is essentially a small incubator designed to protect batteries, which are sensitive to temperature. By raising the room temperature, it reduces the need for air conditioning or even eliminates it. While the main equipment can tolerate higher temperatures, the battery needs protection to maintain its lifespan.
Applicable environment: Suitable for all environments, but not recommended for critical base stations or rooms where air conditioning is rarely used.
Advantages: Helps increase room temperature and reduce air conditioning usage, thereby saving energy.
Disadvantages: Although no major drawbacks exist, reducing air conditioning usage could slightly impact the life of other equipment, though the effect remains manageable.
Rating: ★★★★★
5. Integrated Container Room Efficiency: 50%
An integrated container room is a mobile, pre-fabricated facility that houses all necessary equipment in a standardized and modular design. Unlike traditional brick-and-mortar structures, these rooms are made from specialized materials like containers, making them easy to transport and assemble.
Designed with standardization in mind, integrated rooms offer flexibility in installation, multiple styles, and built-in support modules. They are compact, highly integrated, and allow for phased deployment, helping to balance capital and operational expenditures.
Applicable environment: No special environmental requirements.
Advantages: Improves integration and efficiency, reduces CAPEX, speeds up deployment, and offers cost-effective, easy-to-install solutions.
Disadvantages: Its ability to withstand extreme weather events like hurricanes or earthquakes still needs real-world testing.
Rating: ★★★★
6. DCS Technology Efficiency: 30%
Object-Oriented Cooling (O2C), developed by Zhejiang University and Zhongcheng Technology, is an intelligent distributed cooling system designed for base stations. It uses a series of evaporators connected to an outdoor unit, forming a mini central air conditioning system. The system includes two circulation loops—one for refrigerant and another for water, controlled by compressors and pumps depending on seasonal changes.
Applicable environment: No special requirements.
Advantages: Provides targeted cooling, adjusting airflow based on outlet temperature and using frequency conversion to optimize energy use.
Disadvantages: Due to its proximity to main equipment, it can complicate maintenance and may slightly affect call drop rates due to precise temperature control.
Rating: ★★★★☆
7. Passive Energy-Saving Technology: Over 20%
Passive energy-saving technology focuses on improving the thermal performance of building envelopes and base station equipment. It aims to maintain efficient heat transfer, allowing internal heat from equipment to be easily dissipated.
Applicable environment: Best suited for areas with minimal temperature variation, such as the Northeast region.
Advantages: Saves energy and approaches near-zero emissions.
Disadvantages: Different heat transfer needs exist between summer and winter, making it challenging to adapt. Building structures vary, making uniform modifications difficult.
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.
