An ideal gas is used as a working medium in a left-handed cycle process. The cyclic process consists of three open systems. The gas is initially changed from the initial state 1
(π1 = 20 Β°πΆ, π1 = 0.2 πππ) heated isochorically to a temperature of π2 = 300 Β°πΆ. The gas is then cooled isobaric again to π3 = 20 Β°πΆ. The initial state (state 1) is reached again by an adiabatic throttle.
a) Sketch the cyclic process in the T,s and p,v diagram.
b) What is the coefficient of performance of the cyclic process when it is used as a heat pump?
c) How large is the specific dissipation work when the state changes from state 3 to
State 1 and what specific net heat is provided by the cycle?
d) What is the coefficient of performance if the cyclic process is used as a cooling system?
Calculate with the following values: ππ£ = 700 π½ πΎπβπΎ
task 3
ππ = 1000 π½ πΎπβπΎ
