Did you know that 15-20% of the world’s total electrical consumption comes from the use of refrigeration and air conditioning? Refrigeration compressors are used throughout society for cooling foods, industrial processes, air conditioning, heat pumps and dehumidifiers. For a supermarket or building operator, the electricity cost for cooling is often a hidden cost within the entire bill, but often represents 40-60 percent of the total energy consumed.
Unfortunately the majority of cooling systems today are not working as effectively as they should resulting in higher energy costs and increased carbon dioxide emissions. To reduce power consumption, a clear picture of how the system is working is required. Good analytical tools and methods are the basis for optimizing the operation and minimizing downtime. It has previously been difficult to cost-effectively measure the performance of refrigeration systems in operation.
