Dr. Dermot Cotter's Insights on Energy Efficiency in Refrigeration
Dr. Dermot Cotter's Insights on Energy Efficiency in Refrigeration
The upcoming webinar led by Dr. Dermot Cotter of Star Refrigeration promises to unveil vital insights into energy efficiency in the industrial refrigeration sector. During this highly anticipated Institute of Refrigeration (IOR) TechTalk webinar, Dr. Cotter will share results from extensive site surveys conducted in multiple sectors including food, drink, chemicals, and pharmaceuticals.
Understanding Energy Usage in Various Industries
Titled 'Energy Usage in the Industrial Sector: Food, Drink, Chemical and Pharmaceutical Refrigeration', the extensive study co-authored by Dr. Catarina Marques from London South Bank University highlights a comprehensive analysis funded by the Department for Energy Security and Net Zero (DESNZ). This research is a part of the Transport Industrial and Commercial Refrigeration (TICR) project, aimed at reducing carbon emissions in refrigeration.
Key Findings from Site Surveys
The study draws from meticulous surveys conducted across twenty industrial sites, uncovering significant potential for enhancing energy efficiency while lowering emissions in refrigeration systems. Dr. Cotter stated, "We identified two primary methods for reducing energy usage and carbon emissions in refrigeration. Firstly, designing systems with energy efficiency in mind from the start and secondly, transforming our approach to maintenance. Maintenance should not merely keep systems operational, but actively enhance energy performance."
Industries at a Glance
The research places special emphasis on the Chemical and Pharmaceuticals sectors, which represent a considerable portion of UK manufacturing turnover. The food and drink manufacturing industry is equally significant, representing 17% of total UK manufacturing, with the cold chain playing a crucial role in food preservation.
Insights into Technologies and Maintenance Practices
During the TechTalk, attendees will gain valuable insights into energy usage trends, technology adoption, and the efficacy of maintenance practices prevalent in these essential industries. It has been observed that numerous core refrigeration technologies such as compressors, condensers, and controls are consistent across sectors; however, the types of evaporators employed vary widely according to specific applications, ranging from votators to fin and tube heat exchangers.
The study also assesses the impact of refrigerant choices on carbon emissions, showcasing opportunities for sustainable improvements. Common refrigerants utilized in the systems surveyed included Ammonia, Carbon Dioxide, Propane, and various Hydrofluorocarbons, revealing a complex landscape of energy management strategies.
Maximizing Energy-Savings Potential
Significantly, the research identified that many industrial refrigeration installations hold vast potential for energy savings mostly through superior maintenance routines and better equipment management. At several sites, excessive fouling was reported in air-cooled condensers, leading to increased energy consumption. Simple but effective maintenance practices, such as ensuring clean condensers and diligent monitoring, are highlighted as essential strategies for achieving power reductions of up to 26% in compressor energy usage.
Data Utilization in Optimization Strategies
Despite the clear advantages that data-driven maintenance can bring, the study found that only five surveyed sites had sub-metering for their refrigeration systems. Although these sites tracked their overall electrical consumption, none integrated sub-metering into their maintenance protocols, with only one site employing a refrigeration optimization system that utilized digital twins for monitoring performance.
The Importance of Tailored Equipment Settings
Dive into the study’s conclusions regarding the importance of optimizing evaporating temperatures in industrial refrigeration. The current trend sees suppliers default to standard setups for evaporating temperatures, neglecting tailored adjustments that could drastically boost efficiency. For instance, minor changes in the evaporating temperature could yield substantial energy savings, which underscores the need for customization in refrigeration design.
Through the TICR project, valuable insights and benchmarks are available for businesses looking to optimize both energy use and carbon footprints. Full findings and recommendations catered for end users in manufacturing will be unveiled in the near future alongside a technology roadmap dedicated to reducing emissions.
