What is a subcooled liquid?
The term subcooling (also called undercooling) refers to a liquid existing at a temperature below its normal boiling point. For example, water boils at 373 K; at room temperature (293 K) the water is termed “subcooled”.
How do you know if a liquid is subcooled?
If water exists as a liquid at the saturation temperature and pressure with a quality of x = 0, it is called a saturated liquid state (single-phase). If the temperature of the liquid is lower than the saturation temperature for the existing pressure, it is called either a subcooled liquid or a compressed liquid.
Is subcooled liquid the same as compressed?
A compressed fluid (also called a compressed or unsaturated liquid, subcooled fluid or liquid) is a fluid under mechanical or thermodynamic conditions that force it to be a liquid.
How do you calculate the enthalpy of a subcooled liquid?
Pick a point in the subcooled region at any temperature and pressure (try 20 F and 60 PSIA). Next, try and find the enthalpy (it is around 20 Btu/lb). You will notice that in order to find the enthalpy of this point, you take a vertical line down to the enthalpy value.
How do you calculate Subcool 410A?
Subtract the lower temperature measured on the liquid line from the saturated temperature and you have subcooling!
- 105°F Sat Temp – 93°F Actual Line Temp = 12°F of Subcooling.
- R-410A split system air conditioner.
How compressed liquid turns to a saturated liquid?
Saturated liquid: A liquid that is about to vaporize. At 1 atm and 20°C, water exists in the liquid phase (compressed liquid). At 1 atm pressure and 100°C, water exists as a liquid that is ready to vaporize (saturated liquid).
