Why does my fridge use R600a then? It's taking heat out of the freezer at -19°C and dumping it to my kitchen at 20°C (gas temp 35°C maybe?)

No mention of ammonia. Let’s keep marketing truthful. If you can do it. Great. If you can’t. Don’t say you can do them all. Let’s leave the “f”airy tales to “f” gas folk.

Hello Team Fenagy, Thank you for the fantastic graphic showing the range of temps that your rack mounted equipment is best suited for. It is really a nice chart to learn from! My CO2 heat pump experience since 2016 includes monitoring the operation of four w/w Mayekawa Unimo units at the Alaska SeaLife Center which lift to 90C with load side return temp as low as 20C: 1. For your CO2 heat pumps - your top heat sink temperature of 85C - why do you place that limit there, have you found that operating at higher temps reduces COP, or results in increased compressor wear, etc? What is typical compressor life (in running hours) when operating continuously to produce 85C with return of 40C? 2. For your CO2 heat pumps, your lowest heat sink temperature is shown to be 40C, is this the supply from, or return to heat pumps? If you mean a low supply temp of 40C then return temp would be 20C? We find fantastic COP of over 3.0 in those times when our return to CO2 heat pumps drops down to 20C while lifting to 90C. But the Mycom compressors are wearing out after seven years of heavy use. I am interested to know how a 352KW Fenagy rack mount w/w will perform under similar conditions. Thank you and feel free to email me if needed, Andy
