Important topics of the optimisation are the minimisation of the tube diameters for cost reasons while pressure losses in the lines have to be kept low to ensure energy efficient and also safe operations. Both topics take effect on each other, so it is very important to size tubes properly. This brochure is aimed to give advice for the dimensioning of refrigeration units, which will run with SOLKANE® refrigerants. The tables serve for the dimensioning of horizontal suction-, discharge- and liquid lines and for vertical suction- and discharge-lines as well. Valves and fittings are usually incorporated into pressure drop calculations by using an equivalent length value. This equivalent length is added to the length of the tube of the calculated section. Pressure drop is then calculated for the total resulting length. The values of the equivalent length are availa
