Same procedure as every summer: Science and tech blogging comes to a halt, and the daring ‘internet artist’ is summoned. But also unorthodox avant-garde art is rooted in down-to-earth engineering. In summer elkement leaves the programmer’s cave (a bit) and sees the sun. The local elkemental microcosmos is a fully functional biosphere-2-like ecosystem with lots […]Read More Sources of Heat, Life, and Everything
I had an interesting discussion about the cooling potential of our heat pump system – in a climate warmer than ours. Recently I’ve shown data for the past heating season, including also passive cooling performance: After the heating season, tank temperature is limited to 10°C as long as possible – the collector is bypassed in […]Read More Cooling Potential
Recently I presented the usual update of our system’s and measurement data documentation.The PDF document contains consolidated numbers for each year and month of operations: It is finally time to tackle the fundamental questions: What id the impact of the size of the solar/air collector? or What is the typical output power of the collector? […]Read More The Collector Size Paradox
October – time for updating documentation of the heat pump system again! Consolidated data are available in this PDF document. In the last season there were no special experiments – like last year’s Ice Storage Challenge or using the wood stove. Winter was rather mild, so we needed only ~16.700kWh for space heating plus hot […]Read More Same Procedure as Every Autumn: New Data for the Heat Pump System
Over the holidays I stayed away from social media, read quantum physics textbooks instead, and The Chief Engineer and I mulled over the fundamental questions of life, the universe and everything. Such as: How to explain our heat pump system? Many blog postings were actually answers to questions, and am consolidating all these answers to […]Read More How Does It Work? (The Heat Pump System, That Is)
In the previous post I gave an overview of our recently compiled data for the heat pump system. The figure below, showing the seasonal performance factor and daily energy balances, gave rise to an interesting question: In February the solar collector was off for research purposes, and the performance factor was just a bit lower […]Read More Economics of the Solar Air Collector
We haven’t seen much of it this winter yet. I am talking both about the ice you would expect in winter and about the one created from extracting heat from a water tank – our heat pump system‘s heat source. This winter does again disappoint; it seems we will not be able to generate Pannonia‘s […]Read More We Want Ice!
