Advanced Refrigeration Control, delivered by MPH Global

Once configured, ARC can monitor several parameters across refrigeration packs and cases as well as the local ambient conditions. When pre-determined parameters and conditions are met, the ARC system can then optimize various parameters, allowing the refrigeration system to achieve its optimum level of performance and energy efficiency.

Core Benefits

The solution provides enhanced diagnostics to assist facilities management. These include:

  •  Energy Savings
  • Increased visibility for hardware faults
  • Enterprise Analytics and Dashboards

Security

ARC technology is deemed by customer internal IT to be sufficiently secure from an IT and telecommunications perspective, which should render it compatible with all internal security requirements.

How does it work?

Connected over a secure MQTT connection, the operational data from the site is monitored and reviewed through the cloud-based platform. Appropriate set-points are then adjusted, utilizing the logic controls that are implemented based on pre-defined rules. This can all be implemented remotely with no on-site works required. Example set points which are being optimized are:

Suction Pressure

This assesses case temperatures, ambient temperature, and case alarms. In turn, the outputs comprise an incrementally raised suction pressure, revised maximum valve opening on cases, and revised case control temperature

Superheat

This assesses the external ambient temperature, and when it is achievable, it reduces the useful (evaporator) superheat

Condenser Fan Speed/Start Times

When these are both sufficiently low, optimization will begin, then ramping up as temperatures drop, dependent on the head pressure also remaining low

EC Fan Speed/Start Times

For EC fans, this is a combination of fans start delay and maximum fan speed which increase and decrease respectively as ambient drops.

Staged AC Fan Speed/Start Times

For staged AC fans, a similar logic is applied, but without the maximum fan speed control because the fans can be on at a fixed speed or off
