Q. Graph of suction temperature versus power per ton of refrigeration, keeping condenser temperature fixed in vapor compression refrigeration system in figure is:


Q. The vapour compression refrigeration cycle is represented as shown in the figure below, with state 1 being the exit of the evaporator. The coordinate system used in this figure is


Q. A refrigerator based on ideal vapour compression cycle operates between the temperature limits of −20∘C and 40∘C. The refrigerant enters the condenser as saturated vapour and leaves as saturated liquid. The enthalpy and entropy values for saturated liquid and vapour at these temperatures are given in table below.

Q. A refrigerator uses R−134a as its refrigerant and operates on an ideal vapour compression refrigeration cycle between 0.14MPa and 0.8MPa. If the mass flow rate of the refrigerant is 0.05kg/s, the rate of heat rejection to the environment is \(kW\).
Given data :
At P=0.14MPa,h=236.04 kJ/kg,s=0.9322 kJ/kgK
At P=0.8 MPa,h=272.05 kJ/kg(superheated vapour)
At P=0.8 MPa,h=93.42 kJ/kg(saturated liquid)
Q. A single acting NH3 compressor follows the compression law (PV1.1=C). The operating pressure for the vapour compression refrigeration are: 2.3637 bar (−15∘C) and 11.671 bar (+30∘C). The enthalpy at the exit of compression is 1560 kJ/kg. If refrigerant enters dry saturated to the compressor, then what is the heat loss from the compressor? The refrigeration capacity of the refrigerator is 10 tons..
