Detailed Description

Flat-plate Solar Collector Advanced Technology Professional Quality? Leading Conception----CONSOL Flat-plate Solar Collector. CONSOL flat-plate solar collector: Every solar absorber is with highly selective coating, and the absorber is heat conducting metal. In the middle of absorber, it is water tight seal fitting. The system only could be used under the circumstance of the temperature above zero centigrade. Characteristics of Flat-plate Solar Collector: ▲Flat-plate solar collector is high efficient and pressurized. The life span is about 15 years. ▲Flat-plate solar collector has no anti-freeze function. Therefore, it is suitable for south area use. ▲Specification: 1×2m2? flat-plate solar collector could produce 55℃ hot water: 75－140kg/ m2 if the weather is fine without cloud. ▲High Absorption Efficiency: αs≥92％ Low Emission: εh≤10％? Average Heat Efficiency/Day: ηd≥55％. Adoption of Highly Selective Coating Our products adopt highly selective coating introduced from Germany. This new blue coating is based on Titanium and Quartz which are much more efficient than traditional electroplating black chrome and black nickel coating, it also stands for the innovation of coating in solar industrial. It is coated onto metal tapes continuously with special developed physical vacuum deal(PVD). By means of an electronic beam evaporator, titanium is evaporated under vacuum and condenses onto the metal tape while reacting with nitrogen and oxygen to titanium-oxy-nitride. Additionally quartz is evaporated to forming a second anti reflex-and protection layer. Adoption of optimized technology for professional quality The efficiency of each solar system depending on the capability of its heat transferring rate. It would be basic and easy to reach a high absorptivity of solar enengy, the most challenging should be how to keep solar energy into the metal. This coating does not only have a high absorptivity but also low emissivity which can reduce reflection as well as keep the heat. According to the test, solar collectors equipped with this coating could work much more efficiently even if it’s cloudy. Leading Concept of Application CONSOL takes that the quality and performance higher than anything as its principle, the production and examination of all products are oriented automatically by control of computer. Several spectrometers can analysis or adjust online if necessary. All these data about production would be recorded? and re-examined by experienced quality engineer. This coating with Titanium and Quartz is the only one that can replace that with Nickel or Chrome, its creation would not pollute water or air because it is an environment friendly process. Optical Parameters a. Solar absorptivity :α≈95%±2% b. Emissivity (100℃) : ε≈4%±2% Performance of Cover Glass Adoption of special toughened glass combining with patterns. General Transmittance: 92.01% ( Transmittance of usual toughened glass is about 82%) Direct Emissivity :7.63% CONSOL Flat-plate Solar Collector achieves top level worldwide in important factors as optical parameters and transmittance of cover glass. Our product has an unparalleled performance versus price in the market. The model, performance and parameter of Flat Panel Collector Dimension 2000 x 1000 x 90 Weight 40kg Hot water output during sunny days 70-100kg Temperature of hot water during sunny days 40-800C Maximum working pressure 0.8Mpa Absorption rate of absorption coating 95%+2% Emissivity of absorption coating 4%+2% Transmittance of glass plate >92% Maximum working temperature 120-1600C Dimension of inlet and outlet φ22 Absorption plate material Oxygen free copper Flow pipe material T1 copper Frame material Aerometal Remark: The dimension of the collector could be made according to the requirement.
