4.3.3 Results for the components testing 4.3.3.1 Heat exchanger effectiveness In general heat exchanger effectiveness is defined as the ratio of actual heat transferred in the heat exchanger to the maximum possible heat transfer in the same heat exchanger. For the gas cooler of the CO2 heat pump this would be translated as, ratio of actual heat transferred from the CO2 to the maximum heat transfer possible from CO2. In our case as the gas cooler is cooled by water so maximum possible heat transfer from CO2 will be calculated with the assumption that CO2 is cooled to the water inlet temperature. 4.3.3.1.1 For the 1ST heat exchanger As the gas cooler is divided into three parts with 1st and 3rd reserved for tap water heating application, effectiveness of each heat exchanger was calculated separately. Figure 42 Gas cooler effectiveness with approach temperature at gas cooler outlet (CO2 side) Variation of effectiveness with the variation in the approach temperature for the specific case when 1st heat exchanger was in operation is shown in figure 42. Plot for the three different evaporation temperatures has the same trend, effectiveness is increasing with decreasing approach temperature. 39PDF Image | heat recovery from R744 based refrigeration system
