Evaporative Adiabatic Systems for Creta Farm in Greece_Case Study

Creta Farms taglia la bolletta energetica con la tecnologia adiabatica MITA

Dopo un devastante incendio, Creta Farms ha deciso di ricostruire e installare una soluzione energeticamente efficiente per l’impianto di produzione a Creta.

  • Significantly reduced energy consumption >50%
  • Smaller & cheaper components low pressure system with increased reliability
  • Increased food quality due to more even temperature

Rethymno Production plant

To comply with the new F-gas regulations and to reduce the energy consumption, Creta Farm and ecoRef installs a modern secondary refrigeration system with a high reliability.

The refrigeration installation

The old R22 compressors was in good condition and could be saved and used in the new installation. The new system was designed with R407F as the primary refrigerant and Temper -15 as heat transfer fluid.

The system is water-cooled via a high efficient Mita evaporative condenser which operates with adiabatic method. Aerodynamic type of fan blades are used which minimize energy input from the motors. The motors are directly coupled in the fans minimizing moving components (less maintenance). Mita electronic management system controls condensing temperature and pressure, by continuous calibration of fan speed and water consumption.

Due to the design of taking into consideration condensing pressure and outside temperature the system can run in dry mode, wet mode and mix mode(dry/wet) maximizing energy efficiency and minimizing water consumption.

A buffer tank of 8m3 stores Temper -15 at -6 °C and service the refrigerated areas through a set of electronically con-trolled pumps. The freezer circuit remained a R407F-DX system with electronic expansion valves and Energy Efficient Defrosting
