heating / cooling process #1595

Description of the issue

In #1570 and #1572 the question is raised how to depict the temperature increase of a material. I suggest to create processes heating and cooling to describe that.

Ideas of solution

heating is a heat generation process in which the thermal energy of a material entity is raised, e.g. by raising the temperature level or by phase transition.
cooling is a heat generation process in which the thermal energy of a material entity is decreased, e.g. by lowering the temperature level or by phase transition.

Workflow checklist

[ ] I discussed the issue with someone else than me before working on a solution
[ ] I already read the latest version of the workflow for this repository
[ ] The goal of this ontology is clear to me

I am aware that

[ ] every entry in the ontology should have a definition
[ ] classes should arise from concepts rather than from words

heat pump (technology) an the others are more tricky: 'is about' some ('electric heat pump' and 'participates in' some 'heat transfer')

While in "normal" heat transfers, the thermal energy flows from the higher to the lower temperature. In contrast, in heat transfers involving heat pumps the thermal energy flows from lower to higher temperatures. Maybe we need additional subclasses of heat transfer with normal versus reversed heat flow.

Do you propose these subclasses in addition to heating/cooling?

If we added increase and decrease in #1407, heating could be something like: heating EquivalentTo: increase and ('has energy input' some 'thermal energy') and ('has energy output' some 'thermal energy') and cooling resp. FYI @nelekoehler

cooling is a heat generation process in which the thermal energy of a material entity is decreased, e.g. by lowering the temperature level or by phase transition.

Cooling is always an energy transfer, where the amount of thermal energy that is decreased from material entity A is transferred to material entity B in which the thermal energy increases.
