Reducing The Energy Use of Refrigeration Systems
Our front-end systems, DMTouch and miniDM, offer software features that can increase refrigeration efficiency, facilitate predictive maintenance, and reduce energy consumption.
Energy Management
Businesses are alerted to inefficient equipment that wastes energy so that they can correct the issue quickly.
Predictive Maintenance
Equipment issues are flagged up early before they become serious problems to save operating and repair costs.
Efficient Refrigeration
Multiple software features help enable ideal refrigeration conditions to ensure low operating costs and product quality.
TPI Case Performance
The Temperature Performance Indicator (TPI) informs the user of poorly performing equipment. It is a predictive monitoring solution which helps to easily identify faults before they become a costly issue. TPI monitors the performance of a refrigeration case or coldroom, allocating a score for easy monitoring. The TPI score is based on a number of variables such as the setpoint, differential, over-temperature alarms and under-temperature alarms.
Pack Optimisation
The Pack Optimisation feature typically leads to a 10-30% reduction in pack power, without any interruption or deterioration in case temperature control. The feature enables the target pressure of a pack controller to be adjusted in response to the average valve openings of all the evaporators using that pack. This ensures that all evaporators are used at optimum efficiency and the resultant energy use of the pack compressors is reduced.
Condenser TD
The Condenser TD feature monitors condenser efficiency. DMTouch and miniDM will report three levels of alarm if the condenser is not operating efficiently: pre-warning, warning, and alarm. This allows businesses to take action early to reduce excessive energy consumption. Use of the Condenser TD feature can eliminate the need for pre-scheduled maintenance on this equipment, leading to additional cost savings.
Defrost Warning
The Defrost Warning feature provides a warning when a consecutive number of defrost cycles on a particular evaporator terminate on time setpoint as opposed to the temperature limit. If a defrost cycle terminates on time it may indicate that not all ice has been cleared which will affect efficiency and increase power consumption. The Defrost Warning feature flags up issues quickly to allow businesses to correct the issue to keep costs down.
Network Trim Control
The Network Trim energy feature leads to an overall 30-50% reduction in trim heater load power. Using a humidity and ambient temperature sensor reading, the front-end device will instruct the controllers to adjust their trim heater output levels accordingly. The output level of the trim heaters will be enough to prevent condensation forming without using unnecessary power and will constantly adjust to changing atmospheric conditions.
Night Blinds Detection
Night-blinds covering an open-air refrigerated case after store trading can reduce the power requirement of the case by up to 40%. By comparing different temperature sensors in the refrigerated case, DMTouch or miniDM can identify cases where the night blinds have not been used and generate an alarm. Both front-end systems can also produce a report detailing night-blind use for the store.
