The entire flow range, the 4 tube evaporator pressure a value of ~ a 57 ~ Mian hoe like a cracked 28 No. 4 20O7 in August of Refrigeration JoumdofRefi/gerat/on11o /. 28, No. 4August. 2OO7 downward changes are similar, fluorescent tubes, the evaporator pressure drop than the other tube evaporator increased slightly. L3J3) air-cooled evaporator thermal resistance due mainly to the air side, increase the heat transfer coefficient of refrigerant-side heat exchanger on the whole ... little influence on the heat transfer coefficient, so performed better in single-tube teeth thin tube, Cross-tooth one, in the heat exchanger where performance is not outstanding. However, the above two heat transfer performance of evaporator tube flow changes in the whole range is still better than ordinary evaporator 『51, indicating that cross-tooth tube, thin tooth is the better performance of the heat pipe tube, in particular, cross-gear control,<a href="http://www.christianlouboutinskodk.com" target="_blank">louboutin københavn</a>, as The large number of nucleation is a good evaporation heat transfer tube. 4) When the heat exchanger design, to tube, tube integrated test. 0 into account, improved heat transfer performance of tube, it should be a corresponding increase in tube,<a href="http://www.christianlouboutinskodk.com" target="_blank">christian louboutin</a>, heat transfer performance of the fin side. For example, the cross-tube evaporator tube gear performance is better, if you change the air side finned tube structure, such as mining 『71 red with a better heat transfer fin, the overall heat transfer efficiency will be improved.
