ENERGY SAVING EQUIPMENT
Managing the way to improved efficiency
Anne Flanagan of Star Refrigeration takes a look at energy efficiency management systems.

ising energy costs, carbon taxes, and achieving the EUs fast approaching 20% carbon reduction target for 2020 regulation leaves responsible businesses with significant challenges. The corporate vision of many businesses is focussed on sustainability and reducing impact to the environment in response to legislation and the green consumer expectations.
How the world has changed
An advertisement from Time Magazine in 1962 for a gasoline supplier emphasises how the world has changed and that we have taken huge steps forward in our understanding of how our actions are affecting our environment. The headline,
positioned under a photo of Taku Glacier in Alaska, reads: “Each day we supply enough energy to melt 7 million tons of glacier!” Who could ever imagine that a company would equate its energy sales to its ability to melt ice glaciers in Alaska. The narrative continues: “This giant glacier has remained unmelted for centuries yet the energy we supply could melt it at the rate of 80 tons per second.” Thankfully, we have taken strides forward to redress the behaviours of the past and we would hope to continue to effect and to be proponents of change by looking for ways to reduce our energy consumption
There are many approaches to improving the efficiency of refrigeration plants, including reducing cooling requirements, making appropriate equipment selection and changing operating conditions to reduce the overall temperature lift. However, one of the most substantial savings is achieved by monitoring and analysing the actual operating parameters of the plant when it is running. Too often, the best designed plant is not achieving its optimum COP or anywhere near it because the plant is not properly monitored when it is in operation.
Changing how we think
The introduction of smart metering in domestic properties was rolled out to provide the user with transparency on how they are consuming and being charged for energy. The expectation is that the consumer becomes more focused on their spending when it is clearly displayed with a running counter of use and that it will produce a change in their consumption. The introduction of a smart meter into my home produced a remarkable change in habits. My husband observed the increase in electricity use when the tumble drier was in operation and for the first time in 22 years, he wanted to be involved in how we deal with our laundry. A similar approach is required on a larger scale for industrial and commercial applications. Owners and
