Question 1 An ice making machine operates on the ideal vapour-compression cycle using refrigerant R134a. The refrigerant enters
the compressor as saturated vapour at 160 kPa and leaves the condenser as saturated liquid at 700 kPa. Water enters the ice machine at 15°C and leaves as ice at -5°C. For an ice production rate of 12 kg/hour, determine the power input to the ice maker. (Note: 384 kJ of heat needs to be removed from each kilogram of water at 15°C to turn it into ice at -5°C.)
1 answer:
Answer:
check the attached image for the correct solution
Explanation:
In an ideal vapor-compression refrigeration cycle, the refrigerant enters the compressor as a saturated vapor and is cooled to the saturated liquid state in the condenser. It is then throttled to the evaporator pressure and vaporizes as it absorbs heat from the refrigerated space.
