CFD ANALYSIS
Advantages It does not have any moving parts, makes it simple in construction.
It provides instant cold air in environmental chamber.
The cold air temperature can be easily adjusted with the help of valve.
The output temperature range and mass flow rate can be easily adjusted by changing nozzle bush or orifice bush.
No need of electricity if compressed air is available.
Not require any refrigerant or chemicals.
It is compact; light in weight makes it suitable for aviation application.
It can be worked in any position and at low cost applications.
It does not require any coolant.
It does not have spark or explosion hazard.
Improves tool life and improves finish.
Maintenance free unit.
COP is low
Requires compressed
air
LIMITATION
Limited capacity
Applications
Spot cooling
Cutting tools
Heater-cum-cooler use
Cooling of turbine blades
