Figure 43 Gas cooler effectiveness with variation in heating capacity Plot for the effectiveness with heating capacity (figure 43) shows effectiveness increases with increase in heating capacity, higher heating capacities were obtained at high temperatures and pressures for CO2. One possible explanation is, at high CO2 temperatures more water can be heated to the set point temperature so this increased mass flow (hence increased velocity as well) for water suggests improved convective heat transfer on the water side. Figure 44 cooling and heating profiles with variation in approach temperature Cooling profile of CO2 and heating profile of water is shown in figure 44, as can be seen the increase in approach temperature (high CO2 temperature at gas cooler outlet) there comes a pinch point which limits the heat exchange between the two fluids and hence reduces the effectiveness. 40PDF Image | heat recovery from R744 based refrigeration system
