How HVAC systems contribute to power quality issues in data centers
Data centers serve as the backbone of modern society. They house the servers that keep the digital world running, from the websites we visit to the applications we use and the cloud services that store our data. But while these facilities are indispensable, they’re also energy-intensive, especially their Heating, Ventilation, and Air Conditioning (HVAC) systems.
What many don’t realize is that the HVAC systems used in data centers not only consume a lot of energy but are also a significant source of power quality issues such as harmonic distortions. This blog aims to shed light on the challenges faced by data centers concerning power quality and how Merus Power offers solutions such as Merus® A2 -Active Harmonic Filter that can help address these issues effectively.
The role of HVAC systems in data centers
A large part of a data center’s energy consumption goes into cooling and ventilation to maintain optimal operating conditions for servers and other equipment. The key components of HVAC systems—chillers, cooling compressors, pumps, and fans—are typically powered by Variable Frequency Drives (VFDs). VFDs provide the ability to modulate the speed and torque of motors, thereby making HVAC systems more energy-efficient.
Merus® A2 – Active Harmonic Filter
Merus® A2 is a scalable, versatile, and durable active harmonic filtering solution designed and manufactured in Finland using innovative Merus® technology.
The power quality issue: current harmonic distortions
Unfortunately, the use of VFDs and other electronic components in HVAC systems can result in current harmonic distortions. These distortions are unwanted currents and voltages that can compromise the integrity of electrical systems. A network affected by high levels of harmonics can experience various issues, including:
- Overheating of equipment, reducing their lifespan
- Interference with other devices affecting their performance
- Costly downtime and data losses
- Increased energy consumption and associated costs
And the consequences for data centers?
Data centers are uniquely vulnerable to the consequences of poor power quality. Given the vast amounts of information they store and process, even a minor disruption can have a cascading impact, leading to significant financial losses and data breaches. In addition, poor power quality can reduce the overall energy efficiency of the data center, leading to higher operational costs and a larger carbon footprint.
How can Merus Power help?
At Merus Power, we specialize in offering innovative technological solutions tailored to address the challenges posed by power quality disturbances in data centers. Merus® A2 -Active Harmonic Filter is the superior choice to mitigate harmonic distortions and other disturbances originating from HVAC systems, which in turn boosts overall energy efficiency.
By targeting the energy consumption of HVAC systems, we aim to fulfill several core objectives:
- Improve power quality: As we mitigate harmonic distortions and other power quality issues, data centers can expect to see a marked improvement in the reliability and performance of their electrical systems.
- Increase energy efficiency: By optimizing HVAC systems, we can reduce their energy consumption, thus reducing the environmental impact and operational costs of data centers.
- Minimize downtime and data losses: By stabilizing the power network, our solutions can help avoid costly downtimes and the risk of data loss, making data centers more resilient and reliable.
- Reduce maintenance costs: Better power quality leads to fewer system failures and malfunctions, ultimately lowering the ongoing costs of maintenance.
- Elongate the lifetime of sensitive electrical equipment: By improving power quality, we can extend the life expectancy of sensitive electrical equipment, offering further long-term cost savings.
- Minimize environmental impact: Our solutions significantly reduce energy usage, thus helping data centers lower their carbon footprint and contribute to environmental sustainability.
