Steam ejectors are devices that use steam to create a vacuum by entraining and compressing gases or vapors.
Steam ejectors work by using a high-pressure steam jet to create a low-pressure zone, which draws in gases or vapors from the surrounding area.
The entrained gases or vapors are then compressed and discharged through a diffuser, which increases their velocity and reduces their pressure.
Steam ejectors are commonly u...
Heat pump is a device that transfers heat from a lower temperature to a higher temperature.
Heat pump works on the principle of refrigeration cycle.
