In the previous study , it was shown that the proposed real time control method could be applied for controlling heat rejection pressure of a CO2 refrigeration system and its performance was fairly acceptable. Fig. 5 presents behavior of (COP), cooling capacity, compressor work and expansion valve opening when the real time control method was applied to a CO2 refrigeration system. The CO2 refrigeration system was in steady state with fixed expansion valve opening (11.6%) during the first 400 s and the real time control process suddenly started at 400 s (dashed vertical line). The data is one of the experimental results which are obtained in the previous study by Kim and Kim (2012). The evaporator secondary fluid inlet temperature was 27 C and other experimental conditions are presented in Table 1.

The evaporator secondary fluid inlet temperature was 27 C and other experimental conditions are presented in Table 1.In a previous study found that offered real time control method can be applied to control thermal protection cooling system pressure and the effectiveness of CO2 that is quite acceptable figure 5 shows the behavior (the cop), heat capacity. The expansion valve is open and works on real time control method using a cooling system cooling system CO 2 carbon dioxide in a fixed status extending fixed valve open (11.6%) in the first 400 range and real-time control process began at 400 S (vertical dashed line) is one of the experiments, which is based on a study by Kim and Kim (2012) the level of liquid evaporation temperature is 27° c and the other criteria in table 1 show trial.

In the previous study it was, shown that the proposed real time control method could be applied for controlling heat rejection. Pressure of a CO2 refrigeration system and its performance was fairly acceptable. Fig. 5 presents behavior of (COP), cooling. Capacity compressor work, and expansion valve opening when the real time control method was applied to a CO2 refrigeration. System.The CO2 refrigeration system was in steady state with fixed expansion valve opening (11.6%) during the first 400 s and. The real time control process suddenly started at 400 s (dashed vertical line). The data is one of the experimental results. Which are obtained in the previous study by Kim and Kim (2012).The evaporator secondary fluid inlet temperature was 27 C and other experimental conditions are presented in Table 1.
.In a previous study found that The proposed method the real time control can be applied in the prevention and control of the pressure of the cooling heating system and the efficiency of the CO2. Quite acceptable. Figure 5 show behavior (COP),Heat capacity. The compression and expansion valve opening when the real time control method using the cooling system. CO2 cooling system for carbon dioxide in the steady state permanent expansion valve opening (11.6%) during the first 400 and process the real time control, start 400 S (DASH) is one ในการทดลอง vertical data which is the data in this study. By Kim and Kim (2012) liquid level temperature evaporation is 27 C and other conditions.1.
