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.
