Heatpump Heat / Chill has projected generation of £2,330,197* of income and savings with the 20 year Government Tariff.

“Calibrate created an innovative design that reduced fossil fuel costs and streamlined our systems and processes. It is great to see that this design was seen to fruition with great communication, I would happily recommend Calibrate.”

Tom Cargill

Intelligent Hands Off Heatpump Systems

The Introduction.

The Cargills are based in Laurencekirk, Aberdeen. This Heat / Chill system was designed to Heat the daffodil drying shed, workshop and the grading shed.  There was also a Chilled coil to dehumidify the daffodils, and Chill down the potato store for free. It was agreed that Calibrate’s 1mW Heatpump Heat / Chill system was the perfect solution for their existing technology and a retrofit could be organised.

The Process

Drawing from two decades of Industrial Refrigeration knowledge, the Technical Director Morgan Corkill designed a fully automated simultaneous Heating and Chilling system capable of drying all of the daffodils and then Chilling down the potatoes for free whilst completely removing all fossil fuels onsite and speeding up the process for future development by up to 80%.

The Figures.

  • £2,330,197 of projected income and savings with the 20 year Government Tariff
  • A 4-5 year pay back
  • 25-35°c at 400% heating efficiency
  • 1°c at 325% chilling efficiency
  • Total energy efficiency of 725%

The Conclusion.

100% free Chilling down to 2°c for the potatoes means the Cargills maximise their income. Having opted for the comprehensive 20 year extended warranty they have fixed costs for all R&M to base their future overall income stream upon. A bespoke controller operates the technology via a cloud based system enabling Calibrate to monitor all aspects of the process and tariff generation meters online.

The bespoke Control Package remotely manages the Heatpump, integrating it with other renewables if they are present and enabling a ‘hands off’ approach as well as real time tariff generation and power consumption readings.

Demand Side Response (DSR)

DSR financially incentivises energy users to increase or reduce on demand nonessential energy usage at times of peak or low demand.

Why is demand response needed?

The National Grid has to maintain a certain level of energy production capacity above actual demand. DSR is designed to provide the margin, either by increasing or decreasing site energy use.

What are the benefits of demand side response to you?

The primary business arguments for DSR are financial renumeration and sustainability. DSR not only allows businesses to avoid higher energy prices and receive renumeration during times on and off peak demand.
