Heat Recovery in a Data Center
Problem
A large data center was experiencing high energy costs due to the need for extensive cooling systems to maintain optimal server temperatures.
Solution
The data center installed a finned tube heat exchanger to recover waste heat from the server cooling system and use it for heating the facility during colder months.
Implementation
Heat Exchanger Design: The heat exchanger utilized aluminum tubes and fins, chosen for their lightweight and high thermal conductivity.
Configuration: A counterflow configuration was employed, with the warm air from the server rooms passing over the fins and cooler air from the facility's HVAC system flowing through the tubes.
Results
Efficiency Improvement: The heat recovery system reduced the cooling load by 30%, significantly lowering energy consumption.
Cost Savings: The data center achieved annual energy savings of $500,000.
Environmental Impact: The system reduced the data center’s carbon footprint by 1,000 tons of CO2 annually.
