Forecourt Case Study

The Brief to Consort

Reduce Energy Consumption to the Refrigeration & Air Conditioning Plant on the an Estate of Forecourts by:

• Replacing existing Non Inverter Air Conditioning Systems with Energy Saving Inverter driven units
• Replace existing Air Conditioning Systems running on R22/HCFC Refrigerant with regulation compliant R410a/HFC systems (Zero ODP)
• Replace ageing Chiller/Multideck units with Energy
• Saving units to incorporate LED lighting, Energy Efficient Fans and Cold Air Spillage Controls such as Doors or Nightblinds with Risers
• Retro Fit LED Lights and Cold Air Spillage Controls such as Doors or Risers to existing Chiller/Multideck units
• Replace ageing Cold Room equipment with Energy Efficient Condensing units and Evaporators also to incorporate regulation compliant R404a refrigerant

Replacement Air Conditioning

Over the Estate a decision was made to replace all existing Air Conditioning systems running on R22 refrigerant and Non Inverter Technology.

Consort took advantage of Replacement Technology which reduces the amount of waste materials when changing the system while also causing less disruption to the End User.

Using the Toshiba Super Inverter system specified we were installing one of the most Energy Efficient systems ‘A’ Rated in both Heating and Cooling, also offering excellent COP and EER’s.

Replacement Chiller/Multidecks

We were requested to replace all Chiller/Multideck units beyond a certain age and running on HCFC Refrigerants.

We supplied replacement Chiller/Multideck units incorporating Low Energy EC Fans, LED Lighting which reduce the Energy usage of the unit.

New units also incorporated either Doors or Nightblinds with Risers to reduce the Spillage/Waste of Cold air from the unit therefore reducing the amount of energy used by the cabinet.

Retro Fit Energy Solutions

A large proportion of the program was to replace the lighting through the whole site including the refrigeration display cabinets.

Working alongside a specialist Contractor/Supplier Consort:

• Installed LED lighting in place of existing Fluorescent Tubes
• Installed Vertical Lights within the existing Display Coldrooms
• Retro-fitted Glass Doors or Night Blinds to open Multidecks
• All measures were taken to reduce energy consumption

Retro Fit Door Analyses

By introducing a Retro-Fit Door along with LED lighting it was expected to see savings based upon the attached Graph.

Using the information provided by Cisaplast who manufacture the doors , typical Energy usage would be approximately 25% following retro-fitting to an open multideck.

LED Lighting has also been shown to improve the aesthetic look of the products displayed which could in turn increase sales

Replacing Ageing Coldroom Equipment

Our advise was sought to supply a new Package to existing Display Coldrooms which required replacement equipment due to age and condition.

All existing systems operating on R22/HCFC refrigerant were replaced with a New Energy Efficient Eveporator Internally and Condensing Unit externally. .

All New Coldroom systems provided run on R404a which is one of the most current refrigerants which also has a low Ozone Depleting Potential.

The need for Electric Defrost was eliminated by raising set point temperatures and introducing an off-cycle Defrost setting again reducing Energy Consumption .
