A modern and energy-efficient refrigeration system will help save you money. But you don’t need to buy any new equipment – just following some simple advice can deliver big energy savings.
Here are some no- or low-cost measures that can help you cut your refrigeration equipment’s energy costs by up to 20 per cent.
Our top three recommended carbon saving refrigeration projects:
Minimise the money you need to spend on refrigeration by reducing the heat loads on your systems. You can do this by reducing air infiltration e.g. by improving door management, using night blinds or strip curtains, and switching off lights in the cooled space. In larger systems, you can reduce heat loads by using free cooling, raising process temperatures and improving control of auxiliary equipment such as pumps and fans.

Only cool to the temperature you need – every 1°C saved could reduce your energy consumption by two per cent.

Well-maintained refrigeration systems almost always use significantly less energy. Make sure you regularly service your units, as well as checking that condensers and evaporators are kept clean and fans and defrost systems are working correctly. For example, poor maintenance can increase condensing temperature or reduce evaporating temperature by several degrees, resulting in an increase in energy use of up to 10%.
