Overall energy-saving solution for computer room/base station

In response to the current situation where air conditioning in equipment rooms accounts for a large proportion of total power consumption, Datang Telecom has used advanced refrigeration and heat exchange technologies to launch the "Datang Intelligent Fresh Air Energy Saving System" and "Datang Intelligent Heat Exchange Energy Saving System" that use natural cooling sources to replace part of mechanical refrigeration, as well as energy-saving intelligent air-conditioning appliances for base station air conditioners.

At present, the shortage of electric energy is becoming increasingly prominent, and energy conservation and consumption reduction has become a hot topic of concern to the whole society. The "Outline of the 11th Five-Year Plan" of the State proposes that during the "11th Five-Year Plan", my country should achieve a goal of reducing energy consumption per unit of GDP by 20%, and it has become an important indicator for assessing the performance of governments at all levels. To this end, the state has successively issued relevant policies and regulations such as the "Energy Conservation Law of the People's Republic of China", "Electricity Conservation Management Measures", and "Notice of the General Office of the State Council on Carrying out Resource Conservation Activities", encouraging various power-consuming enterprises to increase their efforts in energy-saving technology transformation.

In order to respond to the national call and assume the social responsibility that enterprises should have, major domestic telecom operators have formulated energy conservation and emission reduction plans and goals. China Mobile has established an "Energy Conservation Office" and a "Green Action Group" to coordinate and manage energy conservation and emission reduction work, and launched a "Green Action Plan"; China Unicom has established an energy conservation and emission reduction leadership group, held an energy conservation experience exchange meeting, and put forward specific energy conservation and emission reduction goals for 2008; China Telecom also started energy conservation and emission reduction issues early, and successively issued the "China Telecom Data Center Room Power Supply and Air Conditioning Environment Design Specifications", "Energy Conservation Implementation Plan", and "China Telecom Energy Conservation Work Guidance".

According to authoritative statistics, the power consumption of communication rooms is the main energy consumption of telecom operators, and air conditioning energy consumption generally accounts for 20% to 45% of the energy consumption of communication rooms, and some even reach more than 60%. Therefore, under the premise of ensuring the normal operation of communication equipment, energy saving should first start with air conditioning.

The specific approach is: install fresh air units and exhaust fans in the computer room. In seasons or time periods when the outdoor temperature is lower than the critical temperature (the supply and exhaust air volume is designed to ensure that the indoor temperature remains within the specified range), the intelligent control host stops the operation of all air conditioners through the air conditioner peripheral interface according to the set program, and starts the supply and exhaust fans in sequence to introduce outdoor low-temperature fresh air into the computer room.

Product use location:

Communication room/base station

Product Applicable Conditions

(1) Access network room/base station with high power consumption.

(2) Install a fresh air energy-saving system in a computer room/base station with good ventilation conditions and an ideal surrounding environment.

(3) It is not advisable to install fresh air energy-saving systems on dusty roads or roads, or around dusty factories and plants such as cement plants and building material processing plants, to ensure that the filter replacement cycle is greater than 30 days.

(4) It is not advisable to install fresh air energy-saving systems in computer rooms/base station access network rooms with relatively high humidity.

(5) It is not suitable for computer rooms that have high requirements for environmental cleanliness.

Product Features

Install this product in the base station/computer room and link it with the air conditioner. When the conditions for the fresh air unit to operate are met, the air conditioner will be turned off and the air conditioner will be used to adjust the temperature of the base station/computer room. This saves electricity and extends the service life of the air conditioner compressor, saving the company's operating costs. The annual electricity saving rate is 20%-60%.

Product advantages and features

When installing the equipment, the vents abandoned the traditional practice of opening square holes on the walls of the machine room, and eliminated the potential safety hazards caused by the openings, effectively solving problems such as base station anti-theft and small animal intrusion. Using temperature and humidity sensors with excellent performance, the linkage between the fresh air unit and the air conditioning unit is completely controlled by temperature, so the power saving rate of the fresh air unit is completely determined by the accuracy of the temperature and humidity sensors. The filter of the fresh air unit is specially treated, which is very convenient to disassemble and clean. It can be reused after cleaning, reducing the cost of operation and maintenance. The air inlet valve and exhaust valve are specially treated to be connected to the wall, which can completely isolate the indoor and outdoor air to meet the requirements of gas fire extinguishing.

3. Datang Intelligent Heat Exchange System

How it works

Taking the outdoor natural environment as the cold source, when the outdoor air temperature is lower than the indoor temperature to a certain extent, the outdoor fresh air is heat exchanged with the air in the computer room through corresponding technical means to take away the heat of the computer room, so as to achieve the purpose of lowering the temperature of the computer room, thereby reducing the use time of the air conditioning equipment and saving electricity. The isolation heat exchange method is adopted to ensure the air temperature requirements of the computer room through the sensible heat exchange between indoor and outdoor air. Since the indoor and outdoor air are isolated from each other, the cleanliness of the indoor air is not affected by the outdoor air.
