In a Bell Coleman refrigeration plant air enters the compressor at a pressure of 1 bar and a temperature of 10°C. It is then compressed to a pressure of 5 bar. Air is then cooled to 25°C in the cooler. Assume both compression and expansion to be isentropic having the value of γ = 1.4, Cp = 1.005 KJ/kgK Then,
1
The theoretical COP is 1.71
2
RE = 95.242 KJ/kg (RE = Refrigeration effect)
3
The theoretical COP is 1.61
4
RE = 92.142 KJ/kg
