Equipment Room Energy Saving Reconstruction Service

Equipment Room Energy Saving Reconstruction Service

1. Refrigerating system energy-saving reconstruction solution

Service content:

l In the original air-conditioning system, add an energy-saving component to provide two refrigeration functions in one refrigerating system.

l Outside the original refrigerating system, add an energy-saving component to form two completely independent refrigerating systems.

Value and features:

l Through reconstruction based on the energy-saving component, fully use the natural cold source under 20°C outdoors. While the cooling capacity is ensured, the runtime of the compressor is reduced and up to 40% of energy saving is achieved.

l Fresh air does not need to be introduced and the temperature, humidity and cleanliness of the equipment room are not affected by the external environment.

l The full intelligent control system provides centralized control and is safe and stable.

Applicable scope:

l In regions in the north of Yangtze River, the outdoor natural cold source is fully used.

l The service is applicable to precision air conditioners of mainstream brands and models for air-cooled equipment rooms.

2. Fan energy saving reconstruction solution

Service content: The indoor fans of precision air conditioners run in a long-term and uninterrupted manner. The energy consumption is large. After original fans are replaced with efficient and energy-saving EC fans, a good energy saving result is achieved.

Value and features:

l After reconstruction, the fan system is more efficient. On the basis of energy consumption of original fans, more than 30% of energy saving can be achieved.

l EC fans run more reliably and reduce the maintenance cost.

Applicable scope:

l The service is applicable to equipment room precision air conditioners of mainstream brands.

3. Reconstruction solution of changing air cooling into water cooling

Service content:

l Water-cooled condensation is used to replace the original air-cooled condensation.

l A water-cooled condensation system is added to the original air-cooled condensation system.

Value and features:

l The condensation system is replaced.

l The cooling capacity is increased.

l The refrigeration power consumption is reduced.

l The stability of the unit is improved and the service life of the unit is extended.

l Water-cooled condensation is used as a supplement to air-cooled condensation.

l Natural cold sources are used to save energy.

Applicable scope

l Aging of air-cooled condensers

l High-temperature areas in summer

l Places with abundance water sources or cooling water

4. Refrigerating system energy-saving reconstruction solution

Service content:

l On the original compressor, add frequency conversion adjustment and control.

l On the outdoor condenser fan, add frequency conversion adjustment and control.

Value and features:

l Add a frequency converter. Up to 30% of energy saving can be achieved in average in a year in an equipment room with variable load.

l Precision refrigeration reduces the startup inrush current and noise of the outdoor unit, ensures system stability, and extends the service life of the unit.

5. Equipment room assessment service

In terms of data center operation, we face many complex and varied circumstances. Is the equipment room air distribution system reasonable? The equipment room assessment service can help you deal with the issue.

Service content:

l Refrigerating system assessment: for example, test and assessment of equipment room air conditioner, air cooled outdoor unit, and chilled water unit

l CFD thermal simulation assessment: for example, assessment of equipment room temperature field, air distribution, and refrigeration efficiency

Value and features:

l A deep “health check” is performed for the refrigerating system to eliminate potential troubles.

l An optimization solution is proposed for the refrigerating system operational efficiency.

l Through CFD thermal simulation, problems in air distribution of the equipment room are found and rectification plans are proposed.

l Air distribution is optimized, the general efficiency is increased, and energy saving is achieved.

6. Other services

Service content: During long-term running of precision air conditioners for equipment rooms, problems such as aging, low heat exchange efficiency, and large noise during operation may exist. For these problems, we propose optimization and reconstruction solutions such as replacing and reconstructing equipment, optimizing energy saving, increasing heat exchange efficiency, and reducing running noise.

Value and features:

l The equipment operational efficiency is increased and the operating cost is reduced.

l Equipment operational stability is improved and fault probability is reduced.

l Highly customizable service solutions meet customer requirements.

Applicable scope:

l The service is applicable to equipment room precision air conditioners of mainstream brands and vendors.
