How much electricity is required to convert 1 cubic meter of gaseous ammonia into liquid ammonia using an ammonia refrigeration unit? Urgent!!!
Thread Content
The experts at HaiChuan need urgent assistance with technical issues. First question: What is the power consumption required to convert 1 cubic meter of gaseous ammonia into liquid ammonia using a refrigeration system? Urgent!!!
You need to know the temperature of your gaseous ammonia and the temperature of liquid ammonia you want to achieve. But by checking their enthalpy values at different states, won’t you be able to figure it out? So others are telling you that you need to provide your specific parameters
Power consumption of centrifugal ice makers: 0.0008 kW/Nm3, while that of screw ice makers is 0.18 kW/Nm3. It is evident that there is a huge difference in power consumption between the two.
Power consumption of centrifugal ice makers: 0.0008 kW/Nm3, compared to 0.18 kW/Nm3 for other types of ice makers. It is evident that there is a huge difference in power consumption between the two. With such a large difference in data, does the screw still have any value here?
Are existing units more commonly used in screw chillers or centrifugal chillers? ? ?
Screw chillers are suitable for low flow rates; their shaft power is generally only a few hundred kilowatts, which is why electric motors are used as drivers for them, and this is the direct reason for their high energy consumption； Centrifugal ice makers have high power levels, usually exceeding 2000 kilowatts, and they are driven directly by steam turbines. The steam consumed in this process is not included in the electricity consumption figures. If the steam consumption were converted into electricity consumption terms, the electricity usage of these ice makers would increase significantly. Nevertheless, it remains lower than that of screw ice makers, and this is due to differences in efficiency. Screw ice makers use a large amount of lubricating oil to cool the machinery, which results in high power consumption; hence their electricity usage is certainly higher.
Oh, we use 1000Kw screw chillers; the new installation is planned to use steam turbines, I learned that
Additionally, I would like to ask the experts: what is the steam consumption of this chiller’s turbine type? Thank you for your help
Which brands are generally used for screw chillers and centrifuges in the synthetic ammonia industry?
