(a)
refrigerating effect is decreased; work required is increased.
Suction Pressure
Delivery Pressure
Supreheating
Subcooling
Suction Temp. and Condenser Temp.
decreased suction pressure is more predominant than increased discharge pressure.
Suction Pressure
Delivery Pressure
Supreheating
Subcooling
Suction Temp. and Condenser Temp.
increased refrigerating effect but also increase amount of work spent to attain the upper pressure limit.
Suction Pressure
Delivery Pressure
Supreheating
Subcooling
Suction Temp. and Condenser Temp.
increased the refrigerating effect; results in increase of COP provided that no further energy has to be spent to obtain the extra cold coolant required.
Suction Pressure
Delivery Pressure
