Seminar for planners, operators, and specialists in cooling and electrical engineering
Deep Dive – Power Supply & Cooling according to EN 50600
Calculating, designing, and assessing data center cooling and power supply: from the cooling load balance to power quality, from the UPS to the metering concept
At a glance
In five days, you learn how the cooling and power supply of a data center work physically and electrically, how they are designed, and where their limits lie: from heat transfer, pressure loss, and the cooling load balance through grounding systems, power quality, UPS, and battery storage to the metering concept according to EN 50600.
You can then verify designs by calculation, assess third-party designs and quotations, and justify decisions on both disciplines with figures.
The cooling part
The seminar goes into the two disciplines that determine the availability and energy efficiency of a data center. The cooling part leads from thermodynamics and fluid mechanics through valves, pumps, and hydraulic balancing to the psychrometric (h,x) chart, refrigeration, and waste heat recovery.
The electrical part
The electrical part covers supply structures, grounding systems, and power quality, the main components from medium voltage to the UPS, battery storage, residual current monitoring, and grounding and equipotential bonding.
Measuring and calculating
The metering concept according to EN 50600, energy management, the German Energy Efficiency Act, and AI in cooling technology connect both disciplines. In calculation exercises, you apply what you have learned yourself.
Depth in the training path
It is the seminar that takes the Data Center Specialist training path into the depth of the two disciplines: one week devoted entirely to cooling technology and power supply.
Why power supply & cooling?
Power supply and cooling are the disciplines on which EN 50600 bases the availability of a data center.
If you can calculate both disciplines, you build in reserves where the Availability Class requires them and nowhere else.
This saves you installations that work on paper but fail in operation due to pressure loss, cavitation, or fault currents, and protects you from quotations you cannot verify. For this, the seminar gives you five days of thermodynamics, hydraulics, and electrical engineering for the data center, with calculation exercises, taught by trainers who know both disciplines from their own design and modernization projects.
Disturbances have a direct effect
According to EN 50600-2-2, disturbances of voltage, current, and frequency directly affect operational safety and availability; according to EN 50600-2-3, excessive fluctuations in temperature and humidity directly affect the functioning of the data center.
Design and measurement
Both parts require a design that supports at least the Availability Class selected for the data center, and both require measurements from which energy efficiency can be demonstrated.
More than the terms
Anyone who implements these requirements in design, tendering, or operation needs more than the terms. They must calculate heat flows, pressure losses, and cooling load balances, assess grounding systems and power quality, understand the standby generator, UPS, and battery storage as an overall system, and set up a metering concept that delivers reliable KPIs.
Tolerance saves energy
EN 50600-2-3 itself states: where wider tolerances for temperature and humidity are permissible, energy can be saved. This requires that you know where the limits of your installation lie.

Content
Six modules
The six modules follow the path of energy through the data center: from the heat that has to be removed through hydraulics and refrigeration to the power supply that carries everything, and to the metering concept that makes both disciplines assessable.
Every cooling system begins with heat that has to be transported. The module lays the physical foundations and carries them over into the design of piping networks, valves, and pumps.
- Tasks and requirements for data centers, typical cooling system configurations, conservation of energy and the laws of thermodynamics, legal situation
- Heat transfer: calculating forced convection and heat conduction, specific heat capacity of water-glycol mixtures, volume flows, frost protection
- Fluid mechanics: laminar and turbulent flow, dynamic pressure and resistance coefficients, pressure loss calculation for piping and duct systems, assessing the work of third parties
- Valves: types, valve authority, kv and kvs value, throttling with two-way valves and mixing with three-way valves
- Static and dynamic hydraulic balancing, basic circuits, throttling elements; pumps as wet-rotor and dry-rotor pumps, pump circuits, cavitation, and pressure maintenance
Whether a computer room stays within the limits for supply air temperature and humidity is decided by air conditions and the cooling load balance. The module leads from the psychrometric (h,x) chart through the refrigeration cycle to the assessment of cooling variants and the use of waste heat.
- Psychrometric (h,x) chart: latent and sensible heat, process lines with heating, cooling, humidification, and dehumidification; determining air flows, air treatment stages, humidifiers, and cooling capacities
- Refrigeration: refrigeration cycle, components of different chillers, selecting the compressor for each application, humidity control, heat rejection systems, and indirect free cooling
- Drawing up the cooling load balance for the computer room from internal and external loads, PUE value, assessing cooling variants by energy efficiency, determining the outdoor air flow rate
- Waste heat recovery: assessing local heating networks and their connection points, outlook on water-cooled processors
The chosen supply structure determines availability and redundancy paths in the data center, and the components from medium voltage to the power strip must be planned as one system. The module connects grounding system, power quality, and main components into a design according to EN 50600-2-2.
- Supply structures: general, safety, and UPS supply along the supply paths; TN-S, TN-C, TN-C-S, TT, and IT systems and their effect on EMC, safety, and availability; the TN-S system as the target system with separation of N and PE and limit values at the central grounding point
- Power quality: environment classes according to EN 61000-2-4, voltage dips, harmonics, and frequency deviations; measurement and automation technology, storage, and UPS as prerequisites for stable power quality in volatile supply structures
- Main components: medium-voltage switchgear with pressure relief, design and parallel operation of transformers, low-voltage main distribution with selectivity, arc fault protection, and withdrawable technology, busbars and power strips in a continuous TN-S system with an EMC concept
- Standby generator: tasks, control power, load profile, low load, and fuel logistics; static and dynamic UPS with selectivity, autonomy time, energy efficiency, and redundancy concepts such as 3N/2
Batteries age with temperature and cycles, fault currents can be detected before they lead to shutdown or fire, and without grounding and equipotential bonding there is neither personal protection nor immunity to interference. The module covers the three topics that determine the service life, availability, and safety of the power supply.
- Battery types for UPS systems (VRLA, VLA), influence of time, temperature, and number of cycles on service life; lithium-ion batteries with their own extinguishing and protection concepts
- Battery storage in the megawatt range: modular design, power and energy content, aging, loss and standby power in the efficiency assessment
- DGUV Regulation 3 (German statutory accident insurance): avoiding shutdowns of fixed installations through permanent residual current monitoring (RCM) according to EN/IEC 62020; relationship between RCM, RCD, fire protection, and availability
- Grounding and equipotential bonding: system, protective, and functional earth, earthing arrangement and meshed equipotential bonding, reinforced protective conductors, requirements according to DIN VDE 0100-540 and EN 50310, implementation on cabinets, racks, and doors
Without measurement, there is no reliable KPI and no proof of energy efficiency. The module shows which quantities must be measured in the data center, how the PUE according to EN 50600-4-2 is derived from them, and how energy management according to CLC/TR 50600-99-1 leads to improvements.
- Measured quantities in the data center: electrical quantities, temperature, humidity, pressure, VOC, and weather data; ultrasonic flow measurement and statistical values for determining installations
- EN 50600-4-2: the PUE as power usage effectiveness, categories and measurement points for each distribution level; a metering concept according to EN 50600 as the basis for comparable KPIs
- Digitalization of the infrastructure: meeting requirements from SLOs and SLAs such as residual current limits, transients, and cold aisle temperature through systematic monitoring
- CLC/TR 50600-99-1: recommended practices covering the building, mechanical and electrical facilities, computer room, racks, IT, and software; monitoring of electrical energy in new builds and refurbishments; example of computer room air handling units; CLC/TS 50600-5-1 as a maturity model for energy management
The German Energy Efficiency Act (EnEfG) sets the legal framework for monitoring and efficiency of data centers in Germany; sensors and machine learning provide the tools to meet it. The module concludes with the obligations under the act and a live demonstration of AI‑based control of cooling technology.
- EnEfG: requirements for data centers, monitoring and KPIs as a contribution to the requirements, guidance on the data points in the data center register
- Sensors in the cold and hot aisle, on power meters, chillers, and weather station as the data basis for machine learning models
- Predictive maintenance, process control, anomaly detection, automated quality control of SLAs, and energy optimization; savings potentials of AI‑based cooling technology and tools to assess them for software and AI‑based measures
- Live demonstration of an AI‑tool for data centers
