TRAINING OBJECTIVES
It allows performing the following teaching activities:
• Identification and study of all the components of solar thermal circuits and of their connections.
• Interpretation of the technical parameters of all the components.
• Dimensioning criteria for of sanitary hot water installations, etc.
• Criteria for assembly and maintenance of the plants.
• Interpretation of the data provided by the control system.
TECHNICAL DESCRIPTION
The trainer simulates the following three operating sections:
PRIMARY SYSTEM
Represented on the panel by the diagram of the circulation of the liquid, coming from the collector, that heats the water contained in the storage tank.
SOLAR THERMAL COLLECTOR
Provided with two temperature probes for the hot (inlet) and cold (return) liquid.
A light sensor detects the solar radiation and allows the plant to be operational or not operational (night).
This part of the circuit is complete with an automatic lowering of the temperature where it is too high in the primary circuit.
SECONDARY CIRCUIT (use of the hot water)
As an application of the production of hot water, the circuit of the use of the hot water that has been obtained is here represented. In this part of the circuit we have: a tank sensor on the hot side, one on the cold side, one at the cold water inlet and one at the used hot water outlet.
Displays and led bars allow the visualization of the temperature values in order to control the operation of the plant.
SOLAR THERMAL HOME PLANT SIMULATOR
Didactic system for the theoretical study of solar plants that are used to get hot water for sanitary and air conditioning purposes or other civil applications.
The simulator allows a wide range of didactic applications.
It also simulates six temperature probes available in different points of the circuit and a solar irradiation sensor that is used to calculate the absorbed energy.
