| 1. Ordinary Evacuated-tube Specification: Structure:All-glass coaxial dual tube Glass material:High borosilicate glass 3.3 Diameter and length of tube(mm): ¦µ47*1200, ¦µ47*1500, ¦µ47*1600, ¦µ47*1800 ¦µ58*1500, ¦µ58*1600, ¦µ58*1600, ¦µ58*1600 ¦µ58*1600, ¦µ58*2000, ¦µ58*2100 ¦µ70*1800, ¦µ70*2000, ¦µ70*2100 Solar selective absorbing coating:Al-N/Al solar selective absorbing coating Absorbance:>91% Emittance:<8% Vacuum degree:<0.002Pa Stagnation parameter:>250m2'Ckw Solar irradiation under stagnation:<2.8MJ/m2 Average heat loss coefficient:<0.8W/m2 degree centigrade Lifetime:15years 2. Three High Evacuated-tube Advantages: High temperature: by special stainless steel aluminum nitride layer, it could bear the high temperature of 500'C,and the film is not falling, not aging. Anti-cold: Super-copper launches mirror, Low reflectance, Small heat loss, good collector results in cold environment, and has hot water. Efficient absorption: high absorption is 92%, reflection reduces 65%, heat increases 12%. higher temperature, more hot water. Specification: Structure All-glass coaxial dual tube Glass material High borosilicate glass 3.3 Diameter and length of tube ¦µ47*1200, ¦µ47*1500, ¦µ47*1600, ¦µ47*1800 ¦µ58*1500, ¦µ58*1600, ¦µ58*1700, ¦µ58*1800 ¦µ58*1900, ¦µ58*2000, ¦µ58*2100 ¦µ70*1800, ¦µ70*2000, ¦µ70*2100 Solar selective absorbing coating: SS-C/CU solar selective absorbing coating Absorbance: >92% Emittance: <5% Vacuum degree: <0.002Pa Stagnation parameter: >250m2'C/kw Solar irradiation under stagnation: <2.8MJ/m2 Average heat loss coefficient: <0.8W/m2'C Lifetime: 15years 3. Three Cavity Evacuated-tubes Advantages: It inner vacuum tube can reduce the water that exchanged, and the water temperature will increase quickly and cycle rapidly. The diameter of ¦Õ58 three-cavity tubes adopt ¦Õ20 inner tubes, the diameter of ¦Õ70 three-cavity tubes adopt ¦Õ37 inner tube. It can reach fast, and high thermal efficiency, avoid furring condensed into plug Specification: Structure:All-glass coaxial dual tube(mm): Glass material: High borosilicate glass 3.3 Diameter and length of tube ¦µ58*1500, ¦µ58*1600, ¦µ58*1700, ¦µ58*1800 ¦µ58*1900, ¦µ58*2000, ¦µ58*2100 ¦µ70*1800, ¦µ70*2000, ¦µ70*2100 Solar selective absorbing coating:Al-N/Al solar selective absorbing coating Absorbance: >92% Emittance: <8% Vacuum degree: <0.002Pa Stagnation parameter: >230m2 c/kw Solar irradiation under stagnation: <2.8MJ/m2 Average heat loss coefficient: <0.8W/m2 degree centigrade Lifetime: 15years |
