Using TES for sustainable refrigeration

Using TES for sustainable refrigeration

Check out this US white paper on how the application of the thermal energy storage (TES) system can improve the operating efficiency of existing refrigeration equipment without costly replacement, while improving the shelf life and quality of perishable foods and other products.

There is now a proven energy storage technology to minimise energy expenses in your low-temperature warehouses and distribution centres. Thermal Energy Storage (TES) can reduce energy costs 20-35% while maintaining stable temperatures and improving refrigeration system efficiencies.

The US refrigerated storage industry is estimated to consume USD13B of electricity annually. In South Africa, we don’t even know what this number is… Electrical cost represents one of the largest components of operating expense of a typical refrigerated facility.

Deemed the most significant technological development in the past 100 years, refrigeration stands paramount to our quality of life and fundamental to the needs of perishable food logistics. The refrigerated storage industry has expanded by 22% over the past 10 years. Because of this, the industry places an emphasis on energy saving technologies.

TES represent a key component of an effective energy reduction strategy in refrigerated space. By using TES as a part of a dynamic system incorporating advanced control of refrigeration equipment, various strategies can be employed to achieve operating cost reductions for a refrigerated facility.

TES represent a stand-alone, minimum maintenance addition to the refrigerated system with an effective lifetime that can exceed that of the mechanical equipment. The system can enable electrical energy savings that affect both the demand and consumption components and can enable a facility to leverage utility rate programmes and discounts offered by electrical utility providers.

Check out this white paper by Hank Bonar, CEO of Bonar Engineering.

Although it refers to the system of a specific supplier later in the document, the core principles relate to TES in general and its application in refrigeration, looking at the benefits and just how much it can really save.
