ASED Consulting International was engaged to provide detailed engineering design and specification for a greenfield Cold Storage & Distribution facility located in Perth, Western Australia. The client was made aware of the superior energy efficiency of Ammonia as a refrigerant, as compared to industry standard synthetic refrigerants and as such opted for a comparison between the different technologies.

Thermal modelling and energy consumption simulations were provided to the client, to which it was made evident that an ammonia-based refrigeration, process cooling and heat pump packages would be best suited to the clients’ multitude of applications and requirements. The thermal modelling and energy consumption simulation nominated the energy efficiencies to be as high as 64.6%, when compared with single stage, industry standard air cooled synthetic based refrigeration systems with electric defrost.

To limit the amount of ammonia stored within the refrigeration system and onsite, a low charge system configuration was implemented.
