Categorization and applications of large solar heating and cooling systemsIEA-SHC TECH SHEET 45.C.1December 2014 - PDF 1.43MB
Solar thermal systems use free energy from the sun (solar radiation) to heat water in a first instance. The solar radiation which is received on the earth plane is called "global radiation", which is made up of direct and diffuse radiation. Depending on the type of collector, in addition to the direct radiation it is also possible to use the diffuse radiation.
The generated heat can be used for different applications and combinations of applications. In the TASK 45 the following classification will be used:
1. General Heating (GH)
2. General Cooling (GC)
3. Process Heating (PH)
4. Process Cooling (PC)
5. Water Heating (WH)
6. Swimming Pool Heating (SH)
7. Relevant Combination (GH & GC)
