This programme applies to factory-made solar collectors units intended to produce hot water or air without forced circulation system for residential industrial application.
Products included in the QB39 program
Are included in the QB39 scope in destination of HVAC engineering installations:
Solar thermal collectors:
- Flat-plate collectors,
- Vacuum tubes collectors.
Domestic solar water heaters (DSWH) without circulator pump or transfer unit:
- Thermosiphons
- Self-storing collectors.
Air flow solar collectors
Hybrid solar collectors:
- Photovoltaic and thermal air collector
- Photovoltaic and thermal water collector
- Thermal solar collectors:
- The aperture area (Aa) and gross surface(AG)
- The thermal characteristics (h0, a1 and a2) in relation to the aperture area and gross area of the solar collector.
- The table of power outputs supplied for three irradiances (400, 700 and 1.000 W/m2) and three temperature gaps (10, 30 and 50 K).
- Domestic solar water heaters (thermosiphons and self-storing collectors):
- The nominal volume of the storage tank (Vn),
- The aperture area of the solar collector(s) in the system (Aa),
- The thermal characteristics (identified parameters) (Ac*, Uc*, Us and Cs)
- The production (expressed as kWh/year) corresponding to a given couple "requirements value/nominal volume".
This production will be given for two meteorological stations: Gillot and Raizet for the French Overseas Departments and Communities (DOM TOM) and Nice for European France.
Note: The thermal characteristics of the “variant designs” of domestic solar water heaters are estimated by calculation. Empirical formulas applied to obtain such thermal characteristics compared with the basic model tested.
- Air flow solar collectors:
- The aperture area (Aa) and gross surface (AG)
- The table of power outputs supplied for three irradiances (400, 700 and 1.000 W/m2) for the three air flows indicated in the technical assessment.
- Hybrid solar collectors:
- The aperture area (Aa) and gross surface (AG)
- The thermal characteristics (eta0, a1 and a2) in relation to the aperture area and gross area of the solar collector.
- The table of power outputs supplied for three irradiances (400, 700 and 1.000 W/m2) for the three air flows(in kg/s or m³/h) and for wind speeds on the collector (in m/s)indicated in the technical assessment.
These certified characteristics are evaluated under the responsibility of EUROVENT CERTITA CERTIFICATION
