Are you looking to reduce your site’s refrigeration energy consumption, costs and carbon?

Our team of expert energy consultants have recently worked with one of our clients in the food service industry to reduce the energy consumption for their refrigeration plant by more than 23%.

So how did SMARTech energy reduce the energy consumption by more than 23%?

SMARTech energy partnered with the company to develop a bespoke energy management strategy through its Energy Efficiency as a Service (EEaaS) programme to help the client to save energy, save money and save carbon.

Detailed data from a site survey, together with the installation of energy monitoring systems enabled our team to understand the energy and carbon consumption at the site.  Our team were then able to recommend energy conservation measures (ECMs) which would help to optimise the energy performance of the existing refrigeration equipment.

What is Energy Efficiency as a Service (EEaaS)?

Energy Efficiency as a Service (EEaaS) is an energy reduction programme which is managed and delivered by our team of experts and guarantees energy savings from 15% to 33%.

With the UK facing continuing pressures from soaring energy costs and government policies encouraging carbon output reduction, SMARTech energy partners with businesses and organisations to efficiently reduce their energy usage and carbon footprint over at least a ten-year period.

With three commercial options available, EEaaS is a shared-savings model which allows organisations to implement energy efficiency plans which utilise one or more of 34 technologies to optimise the performance and operating conditions of a site.

This approach to energy efficiency removes obstacles such a lack of capital, know-how and resource within an organisation and has been adapted to address the changing energy cost environment and provides financial flexibility – with clear strategic energy saving solutions across a whole site – instead of small individual projects and guarantees to deliver the most efficient savings, and all within a few short months.

What energy-efficient technologies and solutions were used to reduce the energy consumption of the refrigeration plant?

SMART Phase Change Material:

SMART PCM is a technology installed inside the freezer area – on the top shelves.  Its purpose is to retain the frozen ambient temperature inside the cold storage areas.  This technology lowers the load on the refrigeration condensers as the temperature inside the cold storage areas is maintained for longer – leading to a reduction in energy consumption.

Voltage Optimisation:

The voltage optimisation (VO) strategy involves the installation of a VO unit on the site’s main incoming supply.  The role of the unit is to optimise the voltage supplied to the site.  This minimises voltage spikes; helping prolong the lifespan of the electrical equipment.  In addition, reduced voltage leads to an overall reduction in energy consumption.

SMART Refrigeration:

The thermostat mounted inside the evaporators are designed to sense the ambient temperature of the cold storage areas.  This sometimes results in inefficient operation of the refrigeration system as it works to cool the ambient air – and not the food stored inside the cold storage areas.

The installation of chilled unit energy savers (CUES) upgrades the existing thermostat located inside the existing evaporating units.  It replicates the thermostatic properties of the foods stored inside the chillers.  CUES allows the refrigeration system to optimally adjust its refrigeration cycle to cool the stored food – not the ambient air inside the cold storage areas.

Power Factor Correction (PFC): 

The power factor correction strategy involves the installation of a PFC unit on the site’s main incoming supply.  The purpose of a PFC unit is to bring the power factor closer to unity by optimising the apparent power (kVA) supplied to the site.  Higher power factor is achieved by maximising the amount of true power (kW), while minimising the amount of reactive power (kVAR) supplied to site.


SMART Mesh is retrofitted on the condensing units of the refrigeration system.  SMART Mesh is designed to pre-cool the ambient air that is supplied to the condensing units.  This results in lower operating load for the refrigeration condensers as the heat difference between the indoor and outdoor ambient temperature is minimised.
