Various kinds of renewable energy sources

What are non-conventional energy sources? First let us understand the word, ‘conventional’ term. Conventional means ‘traditional’ or ‘usual way of doing. Fuels that we normally use daily are called ‘conventional fuels’ and the sources of it called ‘conventional energy sources. These include petrol, diesel, crude oil, gas, etc. Non-conventional energy sources are also called renewable … Read more

How to operate Vacuum Pump and Working of Liquid Nitrogen Plant

Want to know about “How to operate Vacuum Pump and Working of Liquid Nitrogen Plant”?

1. Vacuum Pump

Vacuum requirements are one of the critical factors that affect the cryogenics temperature. Without Vacuum, no cryogenics systems survive. Look at Pulse Tube Cryocooler and related Cryocooler, which always requires a vacuum to keep resists atmospheric temperature and minimize conduction and convection losses because Vacuum is having no medium and heat transfer requires medium except radiation heat transfer. Once you have a Vacuum pump but it is not sufficient, you need to know how to operate it.
