Load profiles

For the simulations daily and weekly load variations for the DHW with hourly resolution were created in order to separate between the ambient temperature dependant SH and independently varying DHW loads. To achieve realistic load profiles, they were created based on measurements from operational plants. 1.1. Measured load profiles Measured hourly load data was obtained […]

Boundary conditions

The simulation study is based on a single family house with a living area of 128 m2 located in Wurzburg, Germany. The roof area where the collectors are mounted is facing south with an inclination of 45o. The space heating demand of the building conforms to the current legal energy saving regulations (EnEV) and amounts […]

Current Study

The current study is an extension to the previous experimental study, however, the objective of the current study is to determine how the heat pump unit responds to a wide range of input temperatures. As well, a goal of the current study is to determine if the steady-state model previously developed in the first study […]

Parameter Variations

A closer look on the results of dimensioning the base case leads to a comprehensive knowledge about the MaxLean system behaviour and the advantages of the concept. To gain insight into the influence the components have on the optimised system, a number of parameter variations were performed. For each variation a new optimisation procedure was […]

Simulated system

There are several possible ways to connect a solar thermal plant to a DH network, with no proven general optimal system layout. The chosen system design principle is shown in fig 2., where the storage tank is connected in parallel with boilers. The control system keeps the outlet temperature from the collector array always above […]
