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
This year we experienced a record-breaking January in Austria – the coldest since 30 years. Our heat pump system produced 14m3 of ice in the underground tank. The volume of ice is measured by Mr. Bubble, the winner of The Ultimate Level Sensor Casting Show run by the Chief Engineer last year: The classic, analog […]Read More Mr. Bubble Was Confused. A Cliffhanger.
In my attempts at Ice Storage Heat Source popularization I have been facing one big challenge: How can you – succinctly, using pictures – answer questions like: How much energy does the collector harvest? or What’s the contribution of ground? or Why do you need a collector if the monthly performance factor just drops a […]Read More Earth, Air, Water, and Ice.
… having studied one subject, we immediately have a great deal of direct and precise knowledge … of another. —Richard Feynman Feynman referred to different phenomena that can be described by equations of the same appearance: Learning how to calculate the distribution of electrical charges gives you the skills to simulate also the flow of […]Read More Frozen Herbs and Latent Energy Storage
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!
We often say we operate in Leonardo da Vinci Renaissance Mode – given our odd ‘portfolio of diverse services’. But as much as the Chief Engineer does not like to work with mortar, cement, or any other slimy substances I tried to avoid pondering about the intricacies of living beings and chemicals so far. But […]Read More Biology / Chemistry Challenge or: Should We Really Blame the Dead Frog?
Despite my attempts to post mainly geeky and weird stuff peppered with (very often not down-to-earth) physics, I got involved in some serious discussions on renewable energy, sustainability, heat pumps, and the pleasures of Building Your Own Stuff. So I will describe what I am actually working on / playing with when I am not […]Read More Controlling the Four Elements. Or: Why Heat Pumps Are Cool.
