Examples of NH3/CO2 secondary systems for cold store operators
The wide acceptance of new technologies depends on a myriad of factors, in the technological, economic and social field, that form part of a complex network of interactions. Both innovators and technology adopters share a common concern for respecting the economic bottom-line and for choosing solutions that provide the highest possible level of investment security while being framed by solid industry support and favourable policy conditions. The industrial refrigeration industry is no exception to this. While the use of ammonia has not been challenged on grounds of lacking energy efficiency nor overall environmental benefits, the trend towards reducing the refrigerant charge for increased safety is currently changing the industry.
This Guide was published to examine what role secondary cooling systems combining the safety and efficiency gains of two refrigerants with lowest negative environmental impact can play in the efficient planning and operation of refrigerated warehouse facilities. It addresses cold store operators, engineers, contractors and investors, but also regulators involved in advancing sustainable refrigeration technologies in the context of the fight against climate change and ozone depletion. By acquiring a greater level of understanding both politicians and the industry can put into place frameworks allowing for a safe, efficient and economically viable use of NH3/CO2 secondary systems.
