Effect of Subcooling
- Increase the refrigeration effect
- Work input remains the same
- Increase in COP
The Degree of Subcooling is the difference between the saturation temperature and the liquid's temperature under that pressure. Subcooling is advantageous because, with no additional particular effort input, it reduces the throttling loss to improve the refrigeration effect.
Additionally, subcooling makes sure that the throttling device receives just liquid, ensuring efficient performance. Water-cooled condensers are one type of condenser that uses subcooling systems. The temperature of the condensed liquid will be lowered by introducing pipes through which cooling water will flow.
Condensers with air cooling - The condenser now has a part where the liquid and gas are separated and where cooled air will be injected.
Dehydrating condensers - When it won't be feasible to reuse the heat that is collected and then released by the evaporation of water, this sort of condenser is employed.
In a refrigeration system, subcooling - (a) Increases COP (b) Decreases COP (c) Increases the work required (d) decreases the work required
Subcooling raises COP in a cooling system. The process of subcooling involves bringing the temperature of the liquid refrigerant below the condensing point for a certain pressure.
