Ice warms bath water - how does that work?

Combined heat, cooling and power generation is similar to the well-known principle of combined heat and power (CHP). Through the skilful operation of compression refrigeration machines, the primary energy sources used are utilised more efficiently, thus reducing CO2 emissions. During the Long Night of Science, we will explain the principle to you using a real ice rink and a hot tub or bathing pool with warm water.

description

The heat that we extract from the freezing water (ice surface) is used to heat the bath water. At present, the process is mostly used in larger systems - for example, to ensure the year-round air conditioning of supermarkets, airports, data centres or industrial buildings. Incidentally, there is a real bobsleigh from the Olympic team of Francesco Friedrich and Jan Grothkopp on the ice rink. You can also try your hand at curling.
