Design and Optimization of Two-Phase Vertical Risers in Refrigeration Systems
In refrigeration systems with vertical risers operating in two-phase flow, pressure drops can significantly affect the system’s Coefficient of Performance (COP). These losses — both dynamic and frictional — reduce evaporator performance and compressor efficiency. In this article, we present a simulation-based analysis of vertical riser performance with special focus…
The Impact of Foresight on Heat Pump Optimization in District Heating
District‑heating operators are under pressure to cut emissions while keeping heat affordable. As large‑scale heat pumps become central to this strategy, the way these units are controlled—particularly with regard to electricity prices and weather forecasts—can have a profound impact on operating costs. This article explores how forecast data, specifically spot…
Comparing Grid Tariffs for District Heating Heat Pumps
With rising electricity costs, the electrification of heat, and the increasing role of heat pumps in district heating systems, choosing the right grid connection can significantly impact annual operating costs. This article compares four different Danish electricity grid tariffs: B-lav, B-høj, A-lav, and A-høj, for a district heating system with…
