The shift towards electrification in district heating creates opportunities to reduce carbon emissions and operating costs, if systems are sized and operated correctly. This white paper examines the optimal sizing of a heat pump and accumulation tank for supplying heat to a single average household with an annual heat…

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…

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…

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…
