Wade Lewis discusses how traditional data center designs are inefficient due to mixing of hot and cold air, which can reduce cooling efficiency by up to 30%. Hot aisle containment is presented as an alternative that prevents this recirculation of hot air, allowing increased supply air temperatures and higher rack densities of up to 30kW per cabinet. This approach maximizes cooling capacity and efficiency through separation of hot and cold air flows.

4 steps to quickly improve pue through airflow management
This document discusses 4 steps to optimize data center cooling through improved airflow management (AFM).
1) Conduct research to identify opportunities by analyzing intake temperatures, hot/cold spots, and cooling capacity factors. Most data centers have excess cooling capacity.
2) Implement AFM best practices like sealing floor tiles and cable openings, using blanking panels, and containing hot/cold aisles.
3) Raise cooling unit setpoints to increase efficiency and release stranded capacity while still maintaining proper intake temperatures.
4) Adjust cooling unit fan speeds and quantities based on modeling results. Case studies showed cost savings from improved AFM within 1.4 years through energy reduction.

This document summarizes an energy modeling analysis that compared the energy performance of seven common gas-fired heating systems for warehouses. The analysis found that direct-fired, high temperature rise blow-thru space heaters used 35-38% less natural gas and 92-93% less fan electricity than the ASHRAE 90.1 baseline system. Using any other type of heater increased energy use by 24-59% compared to the blow-thru heaters. Blow-thru heaters were determined to use the least amount of total energy to heat and ventilate large warehouses based on their design advantages of higher burner efficiency, more efficient controls, and higher discharge air temperatures.

Performance and Optimization of Residential Condensing Combi Systems
Performance and Optimization of Residential Condensing Combi SystemsCenter for Energy and Environment
Homeowners with natural gas water heaters have difficulty justifying the expense of a more efficient condensing heater. Combination space and domestic hot water systems bundle together the two loads, which saves energy and makes them more cost-effective. These systems also help eliminate combustion safety concerns.
Historically, mechanical contractors have custom engineered and pieced together combi systems in the field, paying little attention to efficiency and optimization. But condensing heating plants will only reach their energy saving potential when all components are designed and installed correctly.Carbonare Nicolas - Zusammenfassung MA

Poster on air pcm heat exchanger
The document presents the results of an experimental study on latent thermal energy heat exchangers using paraffin wax as the phase change material (PCM) and air as the heat transfer fluid. Two heat exchanger designs were tested: a tubular heat exchanger with a single PCM storage tube, and a compact heat exchanger model based on an automobile radiator. The experiments analyzed parameters like charging and discharging durations, temperature profiles of the inlet and outlet air, and temperature distribution within the PCM. While the tubular design showed the influence of operating parameters on performance, the compact design demonstrated higher heat transfer but incomplete melting within the PCM due to its low thermal conductivity.

Proper implementation of these strategies can significantly reduce energy consumption and costs while also helping the environment.
Utilization of Computer Room Cooling Infrastructure: Measurement Reveals Oppo...
This document discusses how improving airflow management (AFM) in computer rooms can increase cooling efficiency and save on operating costs. It introduces the Cooling Capacity Factor (CCF) metric to measure cooling output relative to IT load. Research found average data centers have 48% bypass airflow, 20% hot spots, and a CCF of 3.9, indicating overprovisioned cooling. Case studies show how optimizing AFM through techniques like closing unused cooling units can significantly reduce energy costs and cooling infrastructure needs.
white_paper_Liquid-Cooling-Solutions.pdf
The document discusses server cooling challenges as CPUs and GPUs generate more heat. Liquid cooling is presented as a viable alternative to traditional air cooling, as it can remove heat more efficiently and reduce data center operating costs by over 40%. Several types of liquid cooling systems are described, including direct-to-chip cooling, immersion cooling, and rear door heat exchangers. Liquid cooling is shown to improve power usage effectiveness and enable higher performance computing within the same data center footprint. Supermicro offers several server solutions that integrate liquid cooling capabilities.
Passively Cooled Data Centers (Weec 2009)
This document proposes a new design for passively cooled data centers. Currently, data centers rely on air cooling which is inefficient due to the low density of air compared to processor materials. This causes excessive heat buildup near processors. The proposed design separates power supplies from processors to reduce heat, mounts processor boards flush against thermal transfer walls for passive convection cooling without electricity usage, and standardizes board connections for machine handling and optimized processor density within redesigned data center architecture that reuses waste heat. This new approach could open new possibilities for more efficient, lower energy information processing.
Eco cooling

Afcom air control solution presentation
The document discusses improving air flow management in data centers to increase efficiency and savings. It recommends containing hot and cold aisles to better manage airflow, increasing temperature and humidity set points, and installing products like air curtains and blanks to isolate hot and cold air flows. Implementing these strategies increased the number of server racks operating within an optimal temperature range, allowed turning off one CRAC unit for an estimated $35,000 annual savings, and maximized the cooling capacity of CRAC units.
IT cooling for Data Center
Cold/Hot Pool Solutions for DC provides solutions to address increasing heat loads from servers using cold aisle/hot aisle containment strategies. It discusses challenges with traditional cooling methods and how cold aisle containment isolates cold air to better cool servers without mixing with hot air. Hot aisle containment similarly isolates hot air exhaust. These solutions reduce cooling costs by lowering temperature needs and energy consumption compared to traditional methods. Intelligent airflow control methods are also proposed to more efficiently cool server racks based on varying load conditions.
Optimizing The Data Centre Environment
The document discusses various strategies for optimizing the energy efficiency of data centers, including:
1) Establishing an energy baseline and forecasting IT growth to determine optimization opportunities.
2) Implementing metrics like PUE and DCE to measure efficiency and compare to other data centers.
3) Improving airflow management through practices like hot/cold aisle layouts and blanking panels.
4) Matching cooling capacity to IT load and eliminating hot spots through technologies like modular cooling systems.
5) Considering alternative cooling technologies like carbon dioxide cooling that can reduce energy use by up to 30%.
How IT Decisions Impact Facilities: The Importance of Mutual Understanding
This document summarizes a presentation about how IT decisions impact facilities management in data centers. It discusses how choices around server type, server class, equipment airflow patterns, storage type, cooling unit setpoints, cage layout, and airflow management best practices can significantly affect operating costs, capacity, and mechanical systems. Selecting servers with higher delta T or blade servers instead of pizza boxes, for example, can substantially reduce data center cooling needs.
