Field Trials
Seven - 11
The Seven 11 store in North Rocks, Sydney NSW
The equipment to be 'converted' to ERG 1000 was a 'typical' walk in cold room with a 2 HP semi-hermetic compressor operating on R502.
The 'before' test was carried out between 16th March 1998 and April 1st 1998
The 'after' test was carried out between 27th April and May 10 1998.
Apart from the oil change no other components were altered/changed or modified.
The Results
- Consistent increase in COP (coefficient of Performance) after the changeover to ERG 1000
- Increase in COP between 6 - 14% depending on ambient conditions (10% av)
- Discharge and suction temperatures reduced after changeover
The increase in COP will give you more kW of cooling for every kW of electricity used, in this case an average of 10% - in effect reducing your power consumption by 10%.
N.B. This system is quite small, and thus energy savings are expected to be smaller than on larger systems.
The reduction in suction and discharge temperatures means the compressor is not working so hard - and that being the case will last longer.
