PROJECT
INCORPORATING COLD CHAIN designs favour a single, large multiplex system providing both low and medium temperature refrigeration, which offers enhanced diversity and operational flexibility. This is particularly advantageous as it allows continued plant operation even with individual compressor maintenance, improving overall system resilience." He also noted improvements in condenser technology, specifically the integration of adiabatic pads on gas coolers to pre-cool intake air, thereby increasing efficiency.
Addressing the higher initial capital expenditure associated with CO₂ systems, Arnold emphasised the anticipated longterm economic advantages. " From an energy consumption standpoint, the savings are significant. Furthermore, we anticipate that the cost of CO2-specific components, such as compressors and valves, will decrease as market demand increases. Therefore, the long-term operational costs, particularly energy usage which represents a major expense, are expected
Consequently, they are actively exploring the adoption of this integrated approach for refurbishments at other existing store locations. to be considerably lower." The projected substantial reduction in energy consumption throughout the system ' s lifespan is expected to offset the initial higher investment.
