Deviations in simple theoretical cycles
The theoretical cycle applications meet many problems, which lead to change the expected or calculated values.
q Deviations in compression system
•
The suction and delivery valves results
in pressure drops.
•
Leakage
internal and external
is expected.
•
Friction of moving parts.
•
Mixing between lubricating oil and refrigerant.
Mixing between lubricating oil and refrigerant.
q
Deviations in heat exchangers
• The tubes of the heat exchangers causes
considerable pressure drops.To reduce the pressure drops,the internal surfaces must have minimum coefficient of friction. Also
it can be designed with
multi-passes.
•
Tube material must have high
coefficient of heat transfer, with
minimum wall thickness. Tube may have internal and external fins.
