The current research presents the experimental investigation of the effect of tube pitch on enhanced tube bundles’ performance. The typical application of this research is flooded refrigerant evaporators. Boosting evaporator’s performance through optimizing tube spacing reduces cost and energy consumption. R-134a with the enhanced tube Turbo BII-HP and R-123 with Turbo BII-LP were used in this study. Three tube pitches were tested P/D 1.167, P/D 1.33, and P/D 1.5. Each tube bundle includes 20 tubes (19.05 mm outer diameter and 1 m long each) constructed in four passes. The test facility’s design allows controlling three variables, heat flux, mass flux, and inlet quality. The type of analysis used is local to one location in the bundle. This was accomplished by measuring the water temperature drop in the four passes. The water-side pressure drop is included in the data analysis. A new method called the EBHT (Enthalpy Based Heat Transfer) was introduced, which uses the water-side pressure drop in performing the heat transfer analysis. The input variables ranges are: 15-55 kg/m².s for mass flux, 5-60 kW/m² for heat flux, and 10-70% for inlet quality. The effect of local heat flux, local quality, and mass flux on the local heat transfer coefficient was investigated. The comparison between the bundle performance and single tube performance was included in the results of each tube bundle. The smallest tube pitch has the lowest performance in both refrigerants, with a significantly lower performance in the case of R-134a. However, the two bigger tube pitches have very similar performance at low heat flux. Moreover, the largest tube pitch performance approaches that of the single tube at medium and high heat fluxes. For the R-123 study, the smallest tube bundle experienced quick decease in performance at high qualities, exhibiting tube enhancement dry-out at certain flow rates and high qualities. The flow pattern effect was demonstrated by the dry-out phenomena. At medium and high heat fluxes, as the tube pitch increases, the performance approaches that of the single tube. All tube bundles experience quick decrease in performance at high qualities. Evidently, P/D 1.33 is the optimum tube pitch for the studied refrigerants and enhanced tubes combinations.

This experimental study investigates the convective evaporation heat transfer in a flooded evaporator. Experiments were performed using R-134a and R-123 on a plain tube and a fin tube having 15.9-mm-O.D. over a range of vapor qualities (0.03~0.34) with low mass velocities (8kg/m2s to 40kg/m2s) for a wide range of heat flux. Pool boiling data were also tested in the same apparatus. The fin tube having fins of 0.6 mm fin high, 0.6 mm fin pitch, and 0.3 mm fin thickness results in up to 140% boiling performance enhancement over the plain tube. The present experimental data were compared with correlations using superposition and asymptotic models. The superposition-type correlation provided better prediction than the asymptotic model.

The liquid chiller of local want to satisfy Ministry of Economic bulletin “ Air condition system of EER’s stander ”. The flooded evaporator can promote chiller’s efficiency. The study developed a simulation and rating model for the design of flooded evaporator. First, it’s overview heat transfer characteristics of flooded evaporator and boiling on the outside of tubes and tube bundles, several of the relevant empirical correlations were evaluated. Then, it verified and combined with the design procedures into the present program, simulation results obtained by this program were validated by the experiments performed in this study. This program allowed the designers input the selected operating conditions, sizes and materials for the shell and tube, and the arrangement of tubes by using an user-friendly input interface. The design parameters includes water inlet (temperature, flow rate), refrigerant inlet (temperature of evaporator, flow rate, quality), geometry (length, tubes, passes, range of tubes) and oil percent. Furthermore, the accuracy and reliability of the present program is verified and it can be applied to the industries to a large degree.

A theoretical model and computer programming have been developed to predict the heat transfer performance of flooded refrigerant evaporators for specified entering fluid conditions and tube bundle geometry. The nucleate pool boiling heat transfer coefficient is calculating by Cooper’s or by Gorenflo’s correlations, while the boiling heat transfer of shell-side refrigerant is determined by superposition or asymptotic models. A comparison of various combinations, to estimate the heat transfer coefficient of nucleate pool boiling and convective boiling, are presented. The predicted results are compared with experimental data on an R-134a, three-pass, and shell-and-tube type flooded evaporators. The result shows that: the model combined by superposition model and Gorenflo correlation has a good agreement with experimental data. In the case of part-load duty, the model combined by superposition model and Cooper correlation predicted the cooling capacity of evaporator by -20 to +10%. Effect of oil concentration and inlet quality on heat transfer performance was also demonstrated.
