Can helium be used as a refrigerant
WebThe cooled refrigerant gas is sent to a heat exchanger where it can be used to cool down other fluids such as, air, water or other services. In this process, the refrigerant itself gets heated. It is then collected and sent back to the compressor from step1. This way the refrigeration cycle continues. WebIn a thermodynamic cycle it may be the case that the working fluid changes state from gas to liquid or vice versa. Certain gases such as helium can be treated as ideal gases. This is not generally the case for superheated steam and …
