PROJECT PRINCIPLE DIAGRAMProject Solar Hot Water SystemChinatide solar collector manifold leads in large area of project solar heat collection system.This system is made of solar collector (manifold) series and parallel. It is suitable for school,hotel,swimming pool, industrial and mining enterprise domestic and industrial water. It is a wide range of uses, truly energy-saving and reduce pollutants, to reduce CO2 emissions, to improve the quality of human life. The company has designed Central Intelligence Control System, with science design,simple operation to achieve all-weather intelligent management for 365 days,really make people at their pleasure.Double Heat Collect Circulation and Double Tank Circulation with Temperature Control1.When solar collector temperature T1,T2≥50℃,open the magnetic valve to feed water;stop when T1,T2≤40℃.When H1 to 100%,T1,T2≥T3 to 10 ℃ to start the heat exchanger,stop when T2≤3℃2.When T3 ≥ T4 to 10℃ start the heat circulation, close when T3≤T4 to 5℃3.When T4≤35℃,start the electric heater, stop when T4≥55℃.4.When T1,T2≥2℃(environment temp.),start the heat exchanger,stop after 8 minutes, anti-freezing circulation.5.T5 pipe circulation,there is three ways:1.Time circulation.2.Temperature control circulation.3.Temperature differences circulation. When H2≤50℃, start the heat circulation. When T3>T4 to 10℃ start, T3≥ T4 to 2℃ stop. Note: H2≥50% as forced to 6% water level to ensure the electric heater water level.Temperature Differences Circulation1.When T1≥T2 to 10℃,start the heat exchanger; T1≤T2 to 3℃ close.2.When T2<35℃, start the electric heater;≥55℃ stop.3.When T4≤2℃, start heat exchanger, work 8 minutes to stop.Note:anti-freezing circulation.4.When T5≤2℃,start heat tracing band, work 15 minutes to stop. Note:prevent feeding water band freezing.5.T3 temperature is pipe circulation. There is three ways: 1. Time circulation. 2. Temperature control circulation. 3. Temperature differences circulation.6.H1 heat insulation tank level, H1≤50% start magnetic valve feeding water; when H1≥100% stop.Temperature Control to Feed Water and Temperature Differences Circulation1.T1>T2 to 10℃,heat exchanger start, to 3℃ closed. When water level is full, to start H1.2.When T2<35℃,start electric heater, stop at 55℃.3.T4<2℃,start heat exchanger, stop after 8 minutes, to prevent solar collector freezing.4.T5<2℃,stat heat tracing band, stop after 15 minutes, heat tracing band start and close.5.T3 temperature is pipe circulation. There is three ways:1. Time circulation 2. Temperature control circulation (when T3< control temp. Value 35℃ start to work,stop after 10 minutes). 3. Temperature differences circulation (T2>T3 to 6℃ to start,≤3℃ to close).6.H1 heat insulation water and water level, H1<50% to stat the watering magnetic valve;temperature control start at 55℃, and stop at 40℃. When H1 water level to 100%>T2 temperature, start the heat exchanger.
