Question

In a refrigeration system of 10 TR cooling capacity using CHCIF₂, the evaporator and condenser temperatures are –10⁰C and 45⁰C respectively. Properties of CHCIF₂ at saturation are:

Temperature 0C	Sp. volume m3/kg vg	Enthalpy kJ/kg		Entropy kJ/kg-K
		hf	hg	sf	sg
–10 45	0.0654 0.0133	34.25 101.76	247.37 261.95	0.1374 0.3662	0.9473 0.8697

Consider standard vapour compression cycle with inlet to compressor as saturated vapour and inlet to expansion valve as saturated liquid. Assume that vapour may be treated as perfect gas in desuperheating process with average specific heat of 0.9335 kJ/kg-K. show the cycle on T- s and p – h diagrams. Find (i) compressor outlet temperature and enthalpy, (ii) mass flow rate of refrigerant, (iii) work requirement, (iv) condenser heat rejection (v) COP and (vi) Swept volume of compressor in m³/s assuming 100% volumetric efficiency.
