Primary loop
Heating loop in the heat generator with high temperatures for transferring heat with a heat transfer
medium to the → secondary loop.
Process heating PH
Process heating is the heating required for a large number of technical processes and procedures
(drying, cooking, melting, forging etc.). The process heating must typically be generated by
combustion processes or electric current, can however in the best case be recovered in part as waste
heat.
Proportional energy saving
as DIN CEN/TS 12977-2
Rate of price increase [%]
The prices for non-renewable energy sources are rising as a result of growing demand and
increasingly scarce supplies. The development of operating costs and energy consumption play a
crucial role in calculating the capital values of investments.
Redirection valve RV
→ Three-way valve
Return R
The return commonly describes the cooler string in a heating loop. In a solar loop, the return is the
pipe from the storage tank to the collector.
Sankey graph
Graphic representation of energy or material flows using arrows, in which the width of the arrows is
proportional to the width of the flow.
Savings
The simulation results include the reference fuel savings made during the simulation period through
the use of the solar system.
Secondary loop
Heat consumer
Secondary loop
Contains the medium to be warmed, is heated by the → primary loop.
Simulation
Test of the influence of ambient conditions, user behavior, and the various components on the
operating conditions of the solar system with the help of computer calculations
Simulation period
Total period of time for which the simulation is to run. Simulation periods of between one day and
one year are possible
Simulation range
Time interval between two successive calculation steps. It varies between 1 and 6 minutes depending
on the system and is set automatically.
Solar height
-> sun height
Solar azimuth αs
Deviation of the respective position of the sun from the south, constantly changes as a result of
changes in the sun's position, is 0° at 12.00 p.m. CET
