The overall volume compression ratio of a reversed carnot cycle working with air as a refrigerant is 10. the temperature limits of the cycle are 40 degree C and 0 degree C. determine:
1. the pressure, volume and temperature at each point of the cycle,
2. the work done in the cycle
3. the refrigerating effect
4. the COP of the cycle
Determine the evaporator temperature at which a single-stage R22 plant will cease to produce any refrigerating effect in delhi where the condenser temperature is 42 degree C. the and the compressor has 5% clearance, index of compression is 1.15?
