ShareNatural refrigerants used at lower temperature applications.
Number: pap. 31
Author(s) : BOONE J.
Summary
This paper focuses on the natural refrigerants which strongly contribute to the reduction of consumption of fossil fuel and significant reduction of the CO2 emissions. The different system applications are presented in the ‘NATURAL 5 LINE-UP’.
The second part presents the results of operation in the field of a CO2/NH3 cascade refrigeration system installed in a meat processing company in the Netherlands. The contractor ENGIE Refrigeration Netherlands installed a CO2-NH3 cascade plant, with the NH3 part only located in the machine room and on the roof. The plant uses standard and high pressure screw and reciprocating type compressors. The supply of the freezing and the cooling is done with CO2 at –51°C (2900 kW) –35°C and –12°C. In addition heat recovery is done on different temperature levels for process water, and heating of rooms and floors. The paper is supported with technical details and photo’s of each system. As closure for the paper the use of compressor technology is mentioned for demonstrating the feasibility of controlled thermonuclear fusion for power production.
