Hot Air Production Solution: The ThermoFrigoPump (TFP)

Introduction

The ThermoFrigoPump (TFP), developed by Clauger, is a versatile refrigeration system that combines cooling and heating capabilities for industrial processes. Let’s dive into the details:

  1. What is the TFP?

    • The TFP simultaneously provides cooling (from a chiller) and heating (from a heat pump) to meet process requirements.

    • It’s a powerful solution for applications where precise temperature control is essential.

  2. Key Components of the TFP:

    • Piston Compressor: Utilizes the refrigerant 1234ze.

    • Plate Heat Exchanger: Handles the cold side of the process.

    • Finned Coil: Responsible for heating the air.

Practical Case: Upgrading the Dryer

  • Before the Upgrade:

    • The existing dryer relied on fuel heating during weekdays and electric resistance on weekends.

    • This setup can be considered a heat pump, producing hot air above +80°C.

  • Technical Features of the TFP:

    • The absorption dryer processes 10,000 m³/h of process air for confectionery drying.

    • To achieve 100°C air, the TFP specifications include:

      • 21 kW cooling at -1°C using MEG (Monoethylene Glycol).

      • 35 kW heating at 100°C using air.

      • 15 kW electric input.

  • Energy Efficiency:

    • Cooling production with the TFP saves 7 kW of electricity for the Machine Room at -1°C (COP MR = 3), resulting in a COP (Coefficient of Performance) of 4.3.

  1. Overall Ventilation Upgrade:

    • Enhanced regeneration, process, and mixing ventilation.

    • Continuous 10 kW electric gain.

  2. New Air Dryer:

    • Selected to dry with hot air at 70°C.

    • Additional continuous 10 kW electric gain on TFP consumption (COP gain and reduced thermal demand).

  3. Double-Flux Box Replacement:

    • Achieved a continuous 5 kW thermal gain.

  4. Process Control Cabinet Installation:

    • Improved safety and reliability.

Energy Savings Achieved

  • Fuel Consumption Reduction:

    • A significant 355 mWh/year reduction in fuel consumption, leading to complete process decarbonization.

  • Electricity Consumption Reduction:

    • An impressive 195 mWh/year reduction in electricity usage.

  • Client Cost Savings:

    • Approximately €50,000/year reduction in overall costs.

Conclusion

The TFP not only ensures precise temperature control but also contributes to sustainability and cost-effectiveness. Reach out to Clauger today to explore how the TFP can elevate your industrial processes! 🌟💰
