Abstract [en]

Heat pumps have become even more popular when it’s about getting hot water and heat in our departments and villas. Before the heat pumps can be put into operation they have to go through some tests. IVT Industries AB performs the tests in different test rigs depending on the size or effect of the pump. The rig is divided in villapumps and real estate facilitypumps. Testrig F2 is one of the rigs where tests are performed on heatpumps in real estate facility’s. Doing adjustments of hot and cold water today, the IVT company uses cascades PIDcontrollers where the parameters has to be adjust on each tests. Optimization on the controllers have to adjust for the process time to become as short as possible but still there is a time demanded course of event because of the poor stabilitets in the controll and difficult adjustments of the parameters. With help of PID-controllers feedforward we achived.

•Greater stabilitets

•Faster process

•Little adjustments

•Lower energy consumption

•Disturbance free regulation

Abstract [sv]

Värmepumpar har blivit allt mer populära när det gäller att få ut varmvatten och värme i våra fastigheter och villor. Innan värmepumparna skickas ut för drift måste de genomgå en del tester. Hos IVT utförs testerna i olika testriggar beroende på storleken eller effekten på pumpen. Riggen delas upp i Villapumpar och Fastighetspumpar. På IVT finnes Testrigg F2, en av riggarna där man utför tester på Fastighetsvärmepumparna. Vid in justering av varm och kallvatten använder sig IVT koncernen idag utav kaskadkopplade PID regulatorer när man utför tester där parametrarna för regulatorerna måste finjusteras vid varje installation. Regulatorerna optimeras för att få så kort process tid som möjligt men fortfarande är detta ett tidskrävande förlopp pga. Ostabilitet i regleringen och svårtrimmade regulatorer. Med hjälp av PID-framkoppling har vi uppnått.

• Stabilare reglering

•Snabbare processtid

•Små justeringar av regulatorn

•Lägre energiförbrukning

•Störningsfri reglering
