Advantages and Disadvantages of Mixed Refrigerant System
Advantages and Disadvantages of Mixed Refrigerant System
Points : advantages and disadvantages of mixed refrigerant system
Advantages
- Evaporation temperature variation at, a given refrigerating effect or refrigerating effect variations at a
given evaporation temperature is feasible.
- It is possible to reduce condenser pressure by addition of higher boiling point refrigerant.
- If one component lacks stability, this can be increased by adding a component which is more stable.
- The capacity of the same compressor can be increased or decreased by adding different percentages of different
refrigerants.
- Oil miscibility is improved in case of mixtures compared with single refrigerant.
Disadvantages
- The normal operation of the machines is upset if the leakage or one component is in greater proportion on the other.
- It is imperative to now heat transfer co-coefficients of various mixtures at different compositions if
suitable refrigerants in proportions to be chosen.
- It is difficult to design machines working on this system as the thermodynamic properties of all mixtures are
not available in detail.
- From heat transfer point of view, the non-isothermal condensation may prove disadvantageous.
