2.Advantages
2.1 Energy Saving and High Efficiency
Energy saving and high efficiency is the core value of DATACOOL products. Selecting high efficiency components and designing special delay control logic to improve working efficiency.Besides there are 2 running modes available, i.e.: standard running mode and energy saving running mode is alternative. The condensing fan speed is controlled to make the high pressure of refrigeration system within a better range, this saves not only the energy consumption of fan running but also the power consumption of refrigeration system.
2.2 Various Air Flow Pattern
There are 3 kinds of air flow patterns (over flow, under flow, displacement flow), so, the customer is easy to design a best air distribution according to the computer room layout.
2.3 Low Noise and Less Dust
Optional parts are properly selected for DATACOOL series, such as insulation and soundproofing material, quieter cover of compressor, rubber shock holders of raised floor with height adjusting. All above methods can make noise reduction to 5~10dB (A).
The G4 air filter used for DATACOOL series is made of synthetic washable fiber. 80% of 5 μ dust and 20% of 1 μ dust will be filtered by it. It can fully meet the requirements of the cleanness of the indoor air.
2.4 Pretty and Compact
Main parts of DATACOOL series, including panels, bases and frameworks are painted in black, which is very close to the color of the racks. In addition, the height and the depth of the unit are similar to the standard racks. It is nice-looking as its design style matches the devices style inside the computer rooms.
Because of its merits, such as compact structure, small floor space, low weight, DATACOOL is easy to be moved and installed, even in narrow space.
2.5 Safety and Reliability
To guarantee high reliability, compressors, fans, condensers, evaporators, expansion valves and other key components are selected from international famous brands, in accordance with major international industrial standards.
2.6 Intelligent Control
All the components such as compressors, fans, heaters, and humidifier are intelligently controlled and protected by microprocessor.
Comparison between DATACOOL and Normal comfort AC
Comparison topic | DATACOOL | Normal comfort AC |
Product design goal | Build up a high precision temperature and humidity control for the electronic equipment, and give a clean air environment for these equipments, meet the higher requirements of temperature, humidity, purity and reliability from equipment. | Supply a comfortable air environment for the people inside office or residential room. Meet the comfortable requirement of temperature of people inside the room or office. |
Main service object | Electronic equipment or precision instruments | People |
Air circulation volume | Lower enthalpy difference and bigger air circulation volume with circulation times 30-50 per hour, which benefits to the handling of air with high sensible heat. | Big enthalpy difference and small air circulation volume with circulation time 5-10 times per hour, which does not benefit to the handling of air with high sensible heat. |
Basic function | Control both the temperature and humidity | Only control temperature, cannot control humidity |
Energy efficiency | ≥2.9 | ≤2.6 |
Sensible heat | Higher,>0.90 | Lower, 0.6~0.7 |
Supply temperature | Higher, less water condensation | Lower, easily water condensation |
Service working amount | Less | More |
Working life(At the condition of computer room) | >15 years | 2~4 years |
Initial cost | High | Low |
Total cost ownership | Low | High |
Remark:
Obviously from the above table, it is not correct to select normal comfortable air conditioner for the reason of saving initial cost.
DATACOOL Energy saving calculation and comparison
Comparison condition | DATACOOL | Normal AC | |
Product type | Precision | Normal | |
Unit size | 5HP | 5HP | |
Unit cooling capacity | kW | 13.3 | 12.8 |
EER | 2.95 | 2.69 | |
Power consumption of refrigeration system | kW | 4.51 | 4.76 |
Sensible heat ratio | 0.93 | 0.75 | |
Average power consumption of facilities in computer room | kW | 8.5 | 8.5 |
Calculation result | |||
Working hours of AC unit | 6020 | 7756 | |
Total annual heat load from facilities in computer room | kW.h | 74460 | 74460 |
Total annual heat load of humidifier (i.e.: total power consumption of humidifier) | kW.h | 5605 | 24820 |
Total annual heat load of computer room (electronic equipment + humidifier) | kW.h | 80065 | 99280 |
Total annual power consumption of AC unit (Refrigeration + humidification) | kW | 32745 | 61727 |
Annual power saving of DATACOOL unit | kW.h | 28982 | |
Annual working hours ratio of AC unit | 69% | 89% | |
Remark:The above calculation is based on a 30 m2 computer room with 8.5 kW average heat load of equipment. It can be found that the DATACOOL units can save a big amount energy with up to 47% energy saving.
