Refrigeration covers industrial cooling (NH3 ammonia, CO2 transcritical), commercial (supermarket cold chain), low-temperature (-40°C blast freezing) and ultra-low (-80°C lab). Bitzer (DE, compressors Europe #1), Bock, GEA, Mayekawa (JP) and Carrier lead industrial. F-Gas regulation drives CO2 over HFC.

FAQ
Q Ammonia pros and cons?
NH3 pros: high COP (4-5), zero GWP, zero ODP. Cons: toxic (leak detection + emergency ventilation required), incompatible with copper (steel piping). Standard for large cold stores and food freezing.
Q CO2 transcritical systems?
High pressure (80-130 bar) but safe and non-toxic. Suits supermarket refrigeration (95% of new central European supermarkets use CO2). R744 replaces high-GWP HFCs like R404A, R134a. Carel, Danfoss and Bitzer supply CO2 components.
Q Cold-store automation?
Automated high-bay cold stores (-25°C) designed by Dematic, Swisslog and Witron. Stacker cranes, conveyors and AGVs need synthetic lubricants and frost-protection design.
