To validate the foregoing analysis and simulation, some
experiments are conducted. Table 2 shows the effects of gas
injection on the system performance when the glycol inlet
temperatures of the evaporator and the condenser are 5 C
and 30 C, respectively. Table 3 shows the effects of gas
injection on the system performance when the glycol inlet
temperatures of the evaporator and the condenser are 0 C
and 40 C, respectively.
