Innovative hybrid mechanical and cryogenic system for refrigerated transport.

Number: 1107

Author(s) : YOUBI-IDRISSI M.


The refrigerated transport industry is actively looking for innovative concepts allowing higher efficiency and lower environmental impact of its existing and future refrigerated transport fleet.
In this paper, an innovative hybrid concept based on the combination of a conventional mechanical cooling unit and an open cryogenic circuit using nitrogen or CO2 is described Different operation senarios are presented and discussed. The optimal operating conditions will allow achieving the following objectives:
• To downsize the refrigeration unit while maintaining a sufficient cooling capacity when the refrigerated truck is operating at a partial load in steady state or during the temperature regulation phase;
• To be able to reinforce refrigeration requirements during full load operation (pull-down, door opening phases) by integrating a cryogenic system;
• To reduce the energy consumption and enhance performance of both refrigeration and cryogenic systems.
Topics: Sustainable and cost-effective refrigerant options, Sustainability and reduction of the carbon footprint of the entire transport sector, transport and logistics, Reduction of the carbon footprint of refrigerants through refrigerant leakage.
