Traduction Anglaise du CDC fonctionnel Alphasole 2016

Messagepar pachama » Mar Jan 19, 2016 9:18 am

Bonjour à tous,

Ce sujet a pour but la traduction en anglais du CDC suivant:

http://wiki.osefrance.org/doku.php?id=w ... arges_2016

Pour collaborer, on peut scinder le document en paragraphes:
1) exigences de conception
2) général
3) optique de concentration
4) Support du champ de miroirs et du récepteur
5) Structure des facettes miroirs
6) Système de suivi
7) récepteur
8) usage

Ensuite, on peut dire ici le(s) paragraphe(s) que l'on est en train de traduire, et y proposer la traduction terminée pour remarques.

J'espère que ça convient à tout le monde...

Donc je débute le travail, je commence par les § 1,2 et 3.

Benoît.

Technical specifications of the Alphasole Prototype

1) Design requirements

Within the scope of collaborative research, we work on the requirements of each element developped thereafter in the following sections. The discussion history between contributors is available through the links to the forum (in French):

Structure forum link [http://forum.osefrance.org/viewforum.php?f=9] ,
Concentrator optic forum link [http://forum.osefrance.org/viewforum.php?f=10] ,
Engines, Program, Captors forum link [http://forum.osefrance.org/viewforum.php?f=12] ,
Absorber forum link [http://forum.osefrance.org/viewforum.php?f=11] .

2) General

requirement // demonstrator // prototype // comment for proto

Reduce risks // Pay a particular attention to parasitic reflexions // *optical risks; *risks related to high pressure and high temperature hydraulic circuit

Cost (material, production, manufacturing, assembling) // Minimum // Minimum<300€/m² // Savings possible with respect to demonstrator

3) Concentrator optic

requirement // demonstrator // prototype // comment for proto

Optical efficiency // Reflectivity (at normal angle) 0.9 // 60-70% // To be set more precisely: relevant/optimized geometry, cf forum discussion; reflectivity of mirrors >= 0.9 ; other parameters : fouling, cleaning frequency, evolution through lifetime

Robustness and lifetime // no requirement // 3 to 5 years // To be studied : *time? warranty? how much efficiency loss? renewal point, maintenance frequency... *economic balance? *also to be written in other sections : structure, optic... *set more precisely: expensive elements, frame elements last longer: 20 years or more

Accesibility for cleaning and maintenance // no requirement // yes // *easy cleaning of the mirrors; *maintenance and tuning of the facets once mounted; *access to receptor once mounted

Thermal efficiency of the receptor // secondary concentration on the receptor > 1.5 // 70-80% efficiency as a goal

Total concentration factor // between 15 and 30 // between 15 and 30 // With 20 mirrors, it reaches about 15

Secondary reflector (CPC) : design coordinated with absorber // 60% // yes

Voilà, c'est fini.

Je recolle l'intégralité de la traduction ci-dessous.

Il y a par ci par là des trucs pas bien clair pour moi, genre des "60%" qui traînent, mais c'est une autre discussion.

5) structure of mirrors facets

Fresnel mirror: area 2x2 m² with 20 facets 10 cm wide
for use, the requirement regarding the power is to be linked with the area

requirement // demonstrator // prototype // comment for proto

Mirror deformation limitation // deflection lower than 5 mm // 0.1° facet orientation, respectively 1cm on the receptor // (a priori) depends on receptor height, valid for 1.5m height

Optical alignment possible through a tuning needless of special tools // yes // yes


Better: procedure to be updated for calibration

Easy switching of mirror facets // yes // yes // more generally: easy maintenance

*****************************

6) tracking system (engines, program, sensors)

requirement // demonstrator // prototype // comment for proto

Real time accurate tracking of the sun motion // yes // yes // Plan a failsoft mode in case of a failure of the tracking system

Motorisation of mirrors // yes // yes

Electricity consumption // - // Minimum achievable // Plan an autonomous working mode (no connection to electical grid)? (photovoltaic pannel?)

Number of engines // Minimum // One per module or one for all the system // To be validated regarding the other technical choices (structure)

Sun tracking to get the right angle // yes // yes, with necessary accuracy // Goal: send all the beams of each mirror on the width of the recptor (CPC width)

Sensors (weather condition detection) // yes // yes // *ambiant temperature, direct sun radiation. (as a complement of process sensors (boiler and use))

Fluid temperature and pressure measurements // yes // drive the circulating pump controlled by pressure and/or temperature (according to use). Steam flow rate sensor? Liquid water level sensor? => depends on type of use

System automatic shutdown // Optional // Safety in case of electrical outage (circulating pump stopped => temperature increase) + in case of a storm (mirrors down (if possible)). (Resistance to hail?)

Simple controlling panel // yes // Programming expert mode when needed, but simple to use


Ideas: remote access (ethernet)? Ease programming, viewing of operating information (and history?) => To be scheduled secondly. But Arduino ports shall be planned right now

7) Receptor (absorber)

requirement // demonstrator // prototype // comment for proto

Specific design for the working fluid, natural or forced circulation // 100% // yes

Selective material // High absorption qualities through all the solar spectrum : 100% // Absorbance 90%, infrared emissivity 15% : material intrinsically absorptive (or absorptive coating) // = high absorbance through all the solar spectrum and low infrared emissivity

High thermal exchange between absorber and fluid // 60% // yes // material and conduction-convection in the fluid

The system should be thermally insulated (with respect to ambiant air, infrared radiation) // 60% // yes // see requirement for the overall thermal efficiency (insulation material above and glass below)

Good resistance to temperature variation (material expansion, tightness) // 60% // yes // In particular, risks related to high temperatures and pressure of fluid


Ideas: *modularity is hardly compatible with the high constraints of the absorber (pressure, temperature variation etc.) **In case of frost, the absorber should be emptied (or the frost might destroy it). =>Ambiant temperature sensor + electric valve? =>design of the absorber enabling the complete emtying.

8) Use

Requirements to be defined with user

Running

requirement // demonstrator // prototype // comment for proto

Position: avoid building shadow and other masks // - // ?

Running range // - // ? // *for a sun exposure not in first hour nor in last hour, *for which hour range in the day, in the season, * for which latitude

Temperature level // - // ? // Optic and best technology may be different with respect to temperature. Example: *Hot water production at 80°C; *Steam production at 130°C from liquid water; *Steam Superheating from 150°C to 250°C


Hydraulic circuit

requirement // demonstrator // prototype // comment for proto

Pressure losses // - // Minimum // Limit pressure losses, above all for light fluids : air, steam

Open/closed circuit // - // ?

Mineral scale risks // - // ? // Gives good reason to run in a closed circuit...

Fluid // - // ?


Ideas: Could we have a feedback from the user? Which power (mini, maxi average) does he need? During how many hours? And for which season. At my parents', lavander distillery: July. Canned food and Jam from June to september.
