Energy
The cooling process is typically supplied by a centralised ammonia refrigeration compressor, distributed either directly as ammonia, or indirectly through a glycol system.
- Energy transfer from the cooling fluid to the chiller is measured by monitoring the flow rate & temperature of the cooling fluid.
- Energy consumption for the belt drive motor is measured from the inverter drive or using CT clamps on the power line
Operations
Where the chiller is controlled by a local PLC, this data can be collected to enrich the energy & maintenance data, providing vital operational context for different operating modes such as production or defrost.Maintenance
Monitor leading indicators of failure:
- Current & Torque: Drive and chain loadings
- Vibration: Gearbox lubricant condition at low temperatures
- Ultrasound: Bottom bearing wear
Energy
A 500kg/hour freezer, operating at -20C typically consumes circa 250kW of cooling. Assuming the fridge has a CoP of 3, this represents about 80kW of electricity, or around
£100,000/annum cost (at June 2022 prices).
Improving heat transfer by 10% will save around £10,000 per annum.
Operations
These items of equipment are such that, from an operational perspective, there is limited opportunity to improve.
Maintenance
A typical failure could take 24 to 48 hours to fix and lead to a shutdown of the line. At an operating value of around £1,000 per hour, together with the scrapping of all the product currently on the line, the consequence of failure could easily be in excess of £50,000.
