Cold storage energy efficiency is a hugely important topic as energy consumption makes up a large proportion of operating costs for cold storage facilities.
Finding ways to boost energy efficiency ultimately lowers costs and improves profits. In recent years, developments in the industry mean that new strategies have evolved to reduce energy consumption.
Refrigeration systems are a huge consumer of energy in cold storage facilities. Many warehouses use central ammonia systems, but CO2 cascade systems are becoming increasingly popular due to improved energy efficiency. While CO2 cascade systems represent a larger upfront cost, they are safer and typically use 20% less energy than central ammonia systems.
Another cold storage energy efficiency tip is to re-pipe older facilities and check that every pipe is properly insulated. Older pipes can suffer pressure drops that cause energy consumption to increase, while poor insulation also drives up energy bills.
Cold storage energy efficiency can also be improved by reducing the humidity load on refrigeration systems. Installing a desiccant system that removes moisture from air that enters your facility is one way to reduce the load.
You can also use automated refrigeration system controls to optimize the power supply to compressors, evaporators and condensers. By monitoring how much power the system needs to maintain the optimum temperature of the facility at any given time, these control systems can reduce energy costs by cutting consumption when possible.
Another way to cut energy consumption is to reduce the labor and space requirements of your facility. An increasingly common way of doing so is to install automated storage and retrieval systems (ASRS). Using robots means fewer workers are required, and automated systems take up less space than traditional systems that require forklift access.
While ASRS are expensive to install, they are great for energy efficiency. Automated facilities allow for internal lighting to be switched off for the vast majority of the time, cutting energy bills and reducing the load on refrigeration systems.
These days cold storage companies are coming under pressure from clients to reduce their rates, and therefore cutting costs is a top priority. Looking at these cold storage energy efficiency tips means that you can respond to a changing marketplace, and keep your company ahead of the competition.
