Air conditioning systems to improve energy efficiency in information centers - design recommendations
Yossi Dayan
APC by Schneider-Electric
Israel
I am 56 years old and have a bachelor's degree in mechanical engineering from the Technion and a master's degree with honors in business administration.
As part of my various roles, I performed a very wide range of trainings in Israel and around the world on a variety of topics from the content world of the Data Center, such as: Alpac systems, cooling systems, database and communication systems, control and design systems, the DCIM system and more.
I was certified by Schneider Electric as a Solution Architect as well as by the Uptime Institute As an Accredited Tier Designer.
I have rich experience of about 16 years in the field. I managed a wide range of projects that include characterization, planning, consulting and establishment of information centers both in the army in the Central Intelligence Unit and as project manager and in charge of data center products in international companies. Various in a variety of conferences dealing with the field.
In my current position, I am the senior technology director at APC and lead the technological responses of APC and Schneider Electric in everything related to the needs of the physical infrastructure in the information centers.
I am a partner and involved in the design of some of the largest information centers in the country, including mobile systems, among other clients are the Ministry of Defense, Balal, EMC, Bezeq International, Dell, government ministries, Bank Hapoalim, Infinidat and many more.
Summary
The air conditioning component in the information centers constitutes about 40% of the total energy consumption in conventional information centers in hot countries like ours hence the improvement in energy efficiency in this component can lead to a significant improvement in the overall energy efficiency index also known as PUE.
In order to improve this index and streamline energy consumption, there is a global trend of computer equipment developers, communication systems and storage systems, to allow the use of air temperatures and as high a supply of equipment as possible, and on the other hand to use low air flows to cool the equipment.
This data is reflected in the standard issued by the global standard organization TC 9.9 ASHRAE for computer halls, which is classified according to levels 1-4A where level A1 is the highest level that requires pious climate control compared to level 4A which is characterized by a more industrial level less sensitive to climate.
ASHRAE is a member of all the world's leading manufacturers of computer equipment, communications and storage, and they outline the future roadmap in terms of heat loads per square meter in the data centers but also in terms of the required climate.
From looking at the standard it can be seen that the recommended temperature range in the A1 level facility is 18-27C compared to the allowable range of 15-32c, also the relative humidity levels have also risen to a recommended level of 25-60% and a permissible level of, 20-80%, when examining At the same time, computer equipment manufacturers such as Cisco, IBM, HPE and others see that the new temperature range for operating the equipment they allow ranges from 5-35C, however in the settings for the information center design they take into account 27c (which is the top value recommended by ASHRAE). As the air flow to the Lahav server and also the pizzas is getting smaller, the thermodynamic significance of this is the rising air return with a temperature difference of about 12-22 Celsius and even above. That is, with a recommended air supply of 27 degrees we will get a return air of 39-49 degrees Celsius in the hot corridor.
Do refrigeration equipment manufacturers know how to install the supporting equipment in indoor units such as CRAC and InRow? Do they know how to support this in outdoor units such as chillers? What will be the significance of working at such high temperatures on the energy savings of the facility? What will be the output of the chillers in this data? Will it be possible to finally use Free Cooling in Israel as well?
I will answer these and other questions during the lecture.

New Opportunities in UPS Data Center Designs
Abstract
Intelligent approaches to AC power system design in datacenters have become a game changer for traditional design rules and the ground for the development of new design Best Practices. One of the major foundations of datacenters are energy rooms; can we minimize the energy room footprint, energy consumption and weight?
Cyber security, increasing density, and IoT will continue to challenge data center planners in 2018. This top three trends will drive data center owners to search for new solutions to optimize CAPEX vs. OPEX while driving for better TCO.
New UPS system with low footprint, high efficiency, advanced diagnostics combined with Li-ion batteries are the ultimate solution for new datacenters. With High efficiency, we can reach in Israel an energy efficiency and PUE levels that are better than northern European datacenters built only 3-5 years ago. With Li-ion batteries we can improve OPEX and TCO and drastically reduce the expensive battery footprint while improving resiliency and uptime.

New Opportunities for Harvesting Datacenter Free-Cooling in the
Israeli Climate
Abstract
The spiraling costs of datacenter energy makes it necessary to re-examine traditional design rules and to develop new Best Practices. ASHRAE's new guidelines have moved the air supply temperatures to servers to 24-27C. The industry has taken the opportunity and re-designed the chilled water supplies to 20-26C and now to 20-32C. The move to higher water temperatures has not only saved a lot of energy operational costs but has opened up the opportunity for considerable savings from FreeCooling, even in hot climates such as Israel.
With free cooling, we can reach efficiency and PUE levels in Israel that are better than northern European datacenters build only 3-5 years ago. This presentation will analyze and demonstrate the efficiency and PUE that can be attained in cities such as Tel Aviv, Beer Sheva and Jerusalem.

Li-ion UPS - A Revolutionary Combination of Advanced Technologies
Abstract
BENEFITS:
Smaller System footprint & less weight
Increased stored energy availability
Less cooling
Longer Battery life span
Lower Life cycle cost (TCO)
Li-Ion UPS:
Easy scalable 200 kW Power units
Hot scalable up & down
Interactive charging process
Easy maintenance
Li- Ion Technology:
Different Li-Ion cell designs are available:
cylindrical,
pouch,
prismatic.
The prismatic cell design is considered to be the safest as it is equipped with several mechanisms such as a safety function layer,
a multi-layered separator, a safety vent, a safety fuse and an over-charging safety device.
CAPEX Considerations:
It is assumed that the battery systems will perform a limited number of charge / discharge cycles during their working life (30 fullcharge / discharge cycles over 15 years of operation, at a rate of 2 full charge / discharge cycles per year).
The initial battery purchasing price of a 34.68 kWh, 136 cells 63 Ah LIB system is 20,800 € while the purchasing price of a 92.88 kWh, 516 cells 90 Ah VRLA system is 11,150 €.
For a more accurate comparison, a BMS (battery monitoring system) is included as part of the VRLA system With a calendar life of 17 years we can assume that, with a limited number of charge / discharge cycles, the actual working life of the LIB system is close to 15 years.
OPEX Considerations:
Due to their high energy density, LIB systems can provide significant space savings compared to VRLA systems (they take up a lower volume of space for the same BUT, and have a higher efficiency). This is particularly significant for systems installed in Data centers with high real estate costs.
CONCLUSION:
Taking into consideration all the assumptions made above, a 200 kVA UPS LIB system becomes more competitive than a VRLA system after 4 years by reducing the Total Cost of Ownership of the UPS system.
All these factors make the LIB system a winning solution for UPS applications requiring a compact, innovative protection

Existing Critical Facilities Infrastructure Analysis Methodology
Abstract
Critical facilities owners seek to understand the condition of their facilities and to examine the risks it withstands and pitfalls it might have.
TIA 942 as well as Uptime Institute`s Tier level standards define infrastructures characteristics and tier levels that enable to design and build critical facilities that can endure single point of failure and because of that can withstand some failures or downtime caused by maintenance.
It is almost impossible to certify an existing facility and to pass the strict standards demand. In addition, the standards demand that all the disciplines should have the same tier level. According to the standards the rating of a site based in the lowest rating of its individual sub-systems.
The proposed methodology does not pretend to try to certify a critical facility or to create a similar rating. The methodology analysis each disciplines separately and present graphically to the owner the gaps between the current situation and the standard demands.
The differentiation between disciplines: electrical, air conditioning, fuel, communication, Etc. enables to grade the gaps by complexity, by cost and even by the risk it forms and implication on availability to the facility and its purpose.
The owner can understand the week points in the chain. He can prioritize its investments or he can decide that the facility does not support it criticality any more.
The presentation will discuss the differences between discipline characteristics and its implication on the risks. It will present graphic examples from a survey that implemented recently in critical facilities in Israel
