Question

An irreversible heat machine takes 100 kW of heat from a high temperature heat source and throws 50 kW of heat into a low temperature heat well. All work output produced by the heat machine is transferred to a reversible heat pump. The heat pump operates between 17 ° C heat source and 75 ° C heat source. Calculate the heat current transferred from the heat pump to the high temperature heat source as [kW]. Show the process in the diagram T (° C) -s (kJ / kgK).

Answer 1

Que-Greven! Ti = 7501 Q = lookw fan (MP This machine is irreversible This is reversible Heat Pump. Q2 =50kw AL 1+2=170) Solyni – For Heat Machine ♡ from energy balance - W = Q - Q = 100-50= 50kw For reversible Heat Pump => (op) = (COP) cannot Que Ti-T2 w Que 75+27 So 75-17 Qu= 6x50 = 300kw This is heat Currepit transferred Que = = 300 Kw from the Heat Pump to the High temperature Heat sounce. For Heat Pump :- Q 1T1 = 75°C TA (*) 1T2=17°C Ta OL ys (KJ/Kak) 1 # PLS RATE the solun.
