Areverse carnot cycle is used for cooling. r134a is the substance. the cool side is held at 0oc and the warm side at 20oc. the r134a condenses completely from a saturated vapor to a saturated liquid during the heat rejection process. what is the cop of this cooling cycle?
show using
a) a thermodynamics analysis
b) the carnot corollary
