It should be noted that if the natural gas is between 50°C and -160 °C, these refrigerants can be used depending on the specifications of the process. For example, below 1 MPa and in the range of -125 °C to -160 °C , only methane can be used.
Webrefrigerants as theypass through the refrigeration compression cycle also will help you as you study this chapter on refrigerant tables. Part of this chapter deals with a refrigerant (R-22) that will soon be phased out of production. However, as a service technician you maycontinue to come across it for years to come. Be prepared—remember WebA refrigeration effect can also be achieved without using any moving parts by simply passing a small current through a closed circuit made up of two dissimilar materials. This effect is called the Peltier effect, and a refrigerator that works on this principle is called a thermoelectric refrigerator.
