Abstract
The purpose of the ISEC concept is to provide a high-efficient heat pump system for hot water production.The ISEC concept uses two storage tanks for the water, one discharged and one charged. Hot water for theindustrial process is tapped from the charged tank, while the other tank is charging. Charging is done bycirculating the water in the tank through the condenser of a heat pump several times and thereby graduallyheating the water. The charging is done with a higher mass flow rate than the discharging to reach severalcirculations of the water during the time frame of one discharging. This result in a lower condensingtemperature than if the water was heated in one step. Two test setups were built, one to test the performanceof the heat pump gradually heating the water and one to investigate the stratification in the storage tanks.Furthermore, a dynamic model of the system was implemented in Dymola, and validated by the use of testdata from the two experimental setups. This paper shows that there is a good consistency between the modeland the experimental tests.
