RefrigerationCâu 60 / 110
On a system with a condensing saturation temperature of 105 F and a liquid line temperature of 95 F, what is the subcooling?
a.5 degrees
b.8 degrees
c.10 degrees
d.15 degrees
Giải thích
Subcooling equals the saturation temperature minus the liquid line temperature: 105 F minus 95 F equals 10 degrees. This is a typical target range for many TXV systems. Low subcooling can indicate an undercharge, while high subcooling can indicate an overcharge or restriction.
