Design of hydraulic circuits for climate installations

The hydraulic circuit connects and influences the behaviour of all important components of a climate installation. A perceptive quantitative design of this part of a climate installation therefore seems natural and is necessary for installations with a heat pump or heat power connection. Actual practice shows that such is not the case and that especially control of part load operation of the hydraulic circuit should be improved. This article presents a method which at present is being worked out within The Netherlands by ISSO into a design guideline for advisers and installers.
