DL THERMO-A2 / SOLAR THERMAL ENERGY TRAINER WITH REAL SOLAR PANEL – didactic equipment
This trainer must be designed for the theoretical and practical study of solar power facilities used to obtain hot water for sanitation, air conditioning and similar services.
This trainer must consist in a system with a wide range of didactic applications.
It must incorporate six temperature probes available at six different points, and a solar irradiation sensor that will be used to calculate energy. It must be possible the connection of one heat counter at least.
The trainer must be considered as a global system for the theoretical and practical study of solar power facilities, permitting the following teaching and learning activities:
- Identification of all components and how they are associated with its operation.
- Interpretation of the technical parameters of all components.
- Sizing criteria for ACS facilities, air conditioning, etc.
- Assembly and maintenance criteria for facilities.
- Interpretation of situational data supplied by the control.
The trainer shall be comprised of three operating units, as follows:
MAIN MODULE
Dimensions 1000 x 650 x 1650 mm., front panel with the detailed diagram of the system. The synoptic scheme must represent a real hydraulic diagram with the identification of all components.
It must contain the components for the circulation, storage and control of the liquid in the primary and secondary circuits.
The trainer must have openings on the front and back side to allow the students to see the components from each side.
These components must be placed vertically on a base, facilitating comfortable access to all parts for assembly and disassembly operations carried out during the practical sessions described in your handbook.
The front control panel must be placed in the top part of the main module and it is composed of:
o Detailed diagram of the system.
o Electronic control centre with an LCD screen for the visualization of the data.
o Power supply, protections and situation lights.
The hydraulic sockets for cold water inlet, hot sanitary water outlet, connection to the solar panel, etc., must be located at the back of the module.
The plant must be in Ø 15 mm. copper pipe consisting of a pressing system with gaskets for solar plants.
SOLAR PANEL
Real solar panel that must be placed in a metal structure and connected to the main module through flexible pipes, provided with
connections for inlet and outlet flow, solar relief valve with shut off valve. It must be possible to direct the collector from 0 to 90 degrees, with a reference scale suitable for inclination. The collector structure must be in extruded aluminium with black anodizing.
The net absorbing surface must be of 1.36 m2 minimum.
Testing pressure 12 bar
Operating pressure (max) 6 bar
Aluminium absorber with highly selective surface (treatment Mirotherm or Sunselect).
Glass cover, 4 mm, ultra-clear, tempered, micro prismatic.
Insulated with 40 mm rock wool
Hydraulic fittings in corrugated AISI 316 stainless steel with brass connections.
Dim.mm.1300x700x2000
CONVECTOR HEATER
As a means of applying the hot water produced, a convector heater must be available for use. It must be connected through flexible pipes.
This component must allow us to experiment with the effects of hot water obtained with this system. However, the system must be sufficiently open to permit easy use with other applications, such as hot sanitary water supply, under-floor heating, etc.
The convector must be universal European style type composed of:
- Casing
- Galvanized metal sheet coated in light gray plastic
- Fan section
- Axial centrifugal fans
-Motor
- Single-phase with overload protection; three speeds
- Air filter
It must be supplied with manual in English language.
