Comparison and analysis of the performance of all glass evacuated tube solar collector module / parallel system and tiled series system
Series parallel system: this system uses the slope of the south to 30 degrees angle to 45 degrees angle engineering module, spring, summer, autumn sunny every day to produce unstable 45-55 Celsius hot water and daily need energy complementary. Spring, summer, autumn and winter rain on complementary energy tianquan. Solar system almost useless. The system requires a long circulation pipeline, at least 3 times of the series system, large heat loss, low system efficiency and high operating cost. See below for details:
Basic principleThe 1 series parallel system: cold water directly into the hot water storage tank, heat set temperature circulation system, when the water level of water when the hot water storage tank is decreased, the floating ball valve synchronous cold water supply, hot water storage tank hot water used in half can not be reused, the system must be assisted energy complementary, the system basically in temperature cycle system in winter is to assist with solar energy based, supplemented by don't even play a role. See below for details:2 series system: cold water directly into the series collector system, the collector heating, the control system, which meet the conditions of hot water into the water storage tank, storage tank at afternoon storage temperature at high water level, system conversion cycle, the storage tank for heating two times (the system used to control the temperature cycle, temperature cycle + temperature cycle in the company's unique). When the hot water is used, the heat collecting system is added to the energy storage tank to collect the residual heat of the heat collector, so that the heat utilization rate of the solar system is higher. See below for details:
Series system: this system uses the unique vacuum heat collecting tube centralized heat collection universal angle engineering module, spring, summer, autumn sunny day production capacity stable 55-65 Celsius hot water and does not need any complementary energy. Spring, summer, autumn and winter rainy days can be supplemented by complementary solar heat. Complementary energy. The system requires less circulation, small heat loss, high efficiency, low operating costs, is the first choice of solar hot water system in our country:
