Industrial refrigeration : application and technology trends

Process industry cooling

Highly Controled environments: •  allow for ATEX applications > HC’s •  Propylene & Propane availability

Ammonia equally strong R22 phase out : important transition opportunities

Industrial refrigeration Ammonia:

•  Historically most common used refrigerant •  Accounts for most HCFC&HFC conversions

CO2: Settling in negative temperature applications HC & Air: very low temperature applications

Technological trends

Screw vs. reciprocating Pistons: COP↗ & Capex↘ Latest generation Pistons : opex ↘ Minimize refrigerant charge Cascade systems Innovative heat exchangers

NH3/CO2 hybride chiller

Increase efficiency Frequency control, PM motors Advanced valve control systems Multi-stage systems (compound compressors) Heat recuperation Hot gas recuperation vs. Low Tc

system safety Introduction semi-hermetic compressor/motor Ø  Eliminate potential leaks

Motor allignment advantages

Ammonia semi-hermetic piston chilller

Ammonia semi-hermetic screw compressor

Industrial heat pump trends

NH3 : hot water temperatures up to 90˚C •  Using condensing waste heat •  Using stable thermal heat source

HC : allowing to exceed 120˚C temperatures Ø  Competition fossil fuel steam boilers

Mayekawa Industrial Heatpump Water chilling 10˚C to 1˚C / 1MW - 90˚C hot water

Mayekawa Industrial Heatpump 500kW - 70˚C hot water

Butane Industrial heat pump / 120°C steam

Industrial refrigeration Short term challenges

ban R22 : transition turn-around Investments: faster from project to start-up Resource shortage : enhance training Legislation : information & implementation

Industrial refrigeration, natural refrigerants & legislation

Legislation on high & medium GDP refrigerants evolve much faster and tend to be more restrictive worldwide

Industry needs a stable legislative environment

Capex life cycle is 20, 25, 30...years

Natural refrigerants based technology are the ideal solution for sustainable industrial activities.

Thank you very much!
