At point 1 in the diagram, the circulating refrigerant enters the compressor as a saturated vapor. From point 1 to point 2, the vapor is isentropically compressed (i.e., compressed at constant entropy) and exits the compressor as a superheated vapor.

Process 1–2: The working fluid is pumped from low to high pressure. As the fluid is a liquid at this stage, the pump requires little input energy. In other words, Process 1-2 is [Isentropic compression] P-v and T-s Diagram of Diesel Cycle Let the engine cylinder carry m kg of air at point 1. at this point let P1 and T1 and V1 be the pressure, temperature and volume of the air. Following are 4 stages of an ideal diesel cycle.

Kylmediet har fullbordat en cykel. Description. A PV diagram plots the change in pressure P with respect to volume V for some process or processes. Typically in thermodynamics, the set of processes forms a cycle, so that upon completion of the cycle there has been no net change in state of the system; i.e.

The process involved in ideal vapour compression refrigeration is shown in the following fig. The above fig gives the general idea of the refrigeration cycle. Note that there are different vapour compression cycles. Which are listed below.

Draw P-H and T-S diagram when the vapours are superheated at the end of compression and with under cooling of liquid. in actual refrigeration cycles, the temperature of the heat sink wll be several degrees lower than the condensing temperature to facilitate heat transfer. hence it is possible to cool the refrigerant liquid in the condenser to a few

at this point let P1 and T1 and V1 be the pressure, temperature and volume of the air. Following are 4 stages of an ideal diesel cycle. The Carnot cycle is often plotted on a pressure- volume diagram (pV diagram) and on a temperature-entropy diagram (Ts diagram).

First we will see here the PV and TS diagram for Stirling cycle, we will understand here the various processes involved and finally we will determine the thermal efficiency of the Stirling cycle. As we can see here from PV and TS diagram, there will be two reversible isothermal processes and two reversible constant volume processes.
