Fun with Hydrocarbons

I was going to call this post “Playing With Fire” but didn’t for obvious reasons. Anyways, in my last post we saw how CO2 (R744) can be used in both a traditional sub-critical as well as in trans-critical cycles which operate almost backwards to each other. Also, when I typed in trans-critical without the hyphen, Spell Wreck asked me if I meant to type ‘transatlantic’ instead. Um no, but it did remind me of a little bit of history to touch on before we move onto R290. I apologize for the digression but I think you will find it interesting.

Ammonia refrigeration: A staple in the beer industry

“The use of natural refrigerants [like ammonia] is probably more prevalent in breweries than in most industrial or commercial refrigeration plants,” said Mark Bulmer (global segment manager (cooling), GF Piping Systems) at BrauBeviale an international beverage trade fair taking place in Nuremberg, Germany on 8-10 November.

China pushes for standards

As part of the Kigali agreement to phase-down HFCs, under the Montreal Protocol, China is proposing a review of safety standards to remove barriers to alternatives to HFCs, especially natural refrigerants.

Kysor/Warren’s different path

Kysor/Warren, a division and brand of global refrigeration equipment maker Heatcraft Worldwide Refrigeration, is optimistic that deployment of natural refrigerant technologies will expand in the U.S., but the company admits there are some obstacles to overcome.

BITZER: Refrigerant report 19

Stratospheric ozone depletion as well as atmospheric greenhouse effect due to refrigerant emissions have led to drastic changes in the refrigeration and air conditioning technology since the beginning of the 1990s.
