Reducing the heat load on your existing large refrigeration systems can save energy and cut your running costs. It can also reduce the capital cost of a new plant and even eliminate the need to invest in a new plant altogether.
This guide is aimed at users of existing large refrigeration systems such as those in supermarkets, central air conditioning systems, large cold stores and large industrial processes. It will help you to minimise your cooling needs and to meet them as efficiently as possible using the most suitable refrigeration system. Both of these will result in energy savings.
Before you start any refrigeration energy efficiency initiative it is vital to review the heat loads on your cooling plant. If you understand the nature of your loads you can make sure they are met while at the same time minimising the energy cost of your refrigeration systems.
The business case - There are opportunities to reduce the heat load on refrigeration systems at almost all sites. Savings and costs will vary depending on the type of opportunity. Often payback periods are less than one year, and sometimes even no-cost heat load reductions are possible.
If you are planning to install a new plant, reducing its heat load could reduce the capital cost. If your existing refrigeration system currently struggles to supply enough cooling, reducing the heat load on your system could avoid the need for an expensive new plant altogether.
