Technical challenges

Data centers/telecommunication sites need to be cooled 24/7. They optimally operate at 24-28 ⁰C. They are cooled similarly to industrial air conditioning using electrical energy. Unfortunately, the system is the least energy efficient when the temperature difference is the highest (i.e. the outside temperature is too high). However, at night, when the temperature is low outside, the cooling system is more efficient or not even needed.
Also in case of a blackout the cooling systems need 4-6 minutes to restart, during which the servers can quite easily be damaged.

Pain points

Usually our customers are facing with following difficulties:

High cooling costs

The cooling costs reach 40-50% of the total electricity price.

Increasing electricity price

The artificially low electricity price is not sustainable anymore.

Increasing cooling needs

We have to prepare for the increasing needs with oversizing.

Oversized systems

We have to prepare for theincreasing needs withoversizing.

High SLA

The operation safety is the most important.

The solution

By using HeatTank instead of water storage, the storage size can be reduced by 60% and thanks to the optimal storage temperature and higher performance, energy efficiency is 20-40% higher.HeatTank can highly increase the energy efficiency of DCS because cooling systems should produce cooling energy only when it is the most efficient, the cheapest or completely free. Additionally, HeatTanks can be placed not just close to the central chiller unit but in separated branches of the system as well. By doing this, it is possible to turn off some branches from the DCS in case of partial needs, also reduce the heat loss through the pipes and the pumping energy.Large central storages can work in virtual power plant function as well and be part of demand response.

Features

20-50% more efficiency

Electricity saving is between 20-50%. Free-cooling at night & Chiller optimization.

Reduced maintence

The cooling system gets more stable, requiring less maintenance and reduced operation costs.

Higher certification

Higher Tier certification may be targeted through increased operation measures.

Small

Concentrated thermal energy storage. 90% smaller than the traditional water storage and innovative rectangular shape to save space.

Backup cooling

Backup cooling available to bridge restart downtime in case of blackouts. The restart of the newest cooling systems take at least 5 minutes, which could be critical.

Remote control

Visualized energy reports on monthly base to follow the energy saving.

The 25 kWh HeatTank system was installed at 2019 January in the telecommunication base station of MVM Net. We could save 51% energy on the existing system, by using the cooling system, when it is more efficient and using free-cooling.
