Client

The Greyhound Inn is a well-established gastro pub located in the picturesque village of Colton. It prides itself on its food and real ales. It has generous indoor and outdoor spaces that can seat up to 100 customers. The Greyhound Inn has a considerable energy footprint. The large cellar has two refrigeration units running 24/7 to maintain the environment for the specialist beers and ales.


Overview

The purpose of the trial was ‘proof of concept’ and to identify the potential for reducing both carbon emissions and direct energy consumption with the installation of COOLNOMIX - a unique patented intelligent thermostat.


Helix50 carried out a 29-day trial in the cellar.


Trial

2 x AR-01 COOLNOMIX units were installed and connected to 2 x Dakin Refrigeration units (serial no. 205991501-00271 and JEHS-0200-B2-M-1) located in the cellar. To measure the energy consumed by the cooling, an MID smart meter with remote connectivity was connected to the external condenser (DET 14011747) during the trial.


Data recording commenced on the 28/04/2020. COOLNOMIX (ON) was operational until 13/05/2020 (15 days) at which time it was turned off on 13/05/2020. COOLNOMIX was bypassed (OFF) and the cooling systems operated as ‘normal’ for 14 days from 13/05/2020 until 27/05/2020.


During the 29-day trial, the metered half-hourly and 4-hourly data was collected and analysed.


Results


Daily

COOLNOMIX active (ON) reduced daily energy consumption by 57%, providing an average daily reduction of 12kWh.

Figure 1

This saving is based on using 132kWh over 15 days with COOLNOMIX active (ON) and 292kWh over 14 days with COOLNOMIX inactive (OFF).


Annual

The measured 12kWh daily saving for two COOLNOMIX devices equates to an annual combined saving of both refrigerators of 4,380kWh which is equivalent to an annual carbon emissions reduction of 1,248.3kg CO2.


Figure 2

The annual savings were calculated on an average daily consumption showing:

  • COOLNOMIX (ON) consumption averages 8.8kWh

  • COOLNOMIX (OFF) consumption averages 20.8kWh

  • COOLNOMIX will reduce your carbon emissions by 1,248.3kg of CO2 per annum


Summary

COOLNOMIX was installed and the data proved the technology’s worth against the two refrigeration units in the cellar. The savings we achieved surpassed all expectations, offering a 57% energy saving and a monthly saving of £24.27 per COOLNOMIX device.


Over 10 years The Greyhound Inn would achieve:

  • CO2 reduction 12,483kg

  • Electricity reduction 43,800kWh
