I need help: what are the common refrigerants used in the chemical industry?
Thread Content
What are the commonly used refrigerants in the chemical industry? What is the material code corresponding to it in the flowchart? For example, seeking help with the inlet water for the WS circulating water system! !
It would be great if the temperatures corresponding to each refrigerant could be provided. Thank you very much
Frozen brine BRS/BRR, circulating water CWS/CWR, ethylene glycol aqueous solution CHS/CHR – these are commonly used; there are also low-temperature media
Each company has its own approach; there are no fixed rules. For CWS/CWR circulating water, the values can be 32 or 33, depending on local conditions. The same goes for other types of low-temperature water and chilled water – there is no fixed standard either; anyone can choose whatever code they want to use
