Rong l Split solar water heater a solar house . Rong l Solar System Features The system can be installed in residential villas on south-facing roof can also be installed in the villa's garden lawn, and a variety of buildings on the south-facing slope , hot water can be sent to the unrestricted use of any one floor , wide application . The system uses the work forced circulation ( automatic control ) work, and automatic temperature control , pressure water , to solve the long-standing solar water heater manual operation inconvenience . The system is less investment , the effect is good , simple operation, more importantly, safe, convenient , energy saving, no pollution to the environment , so praised by experts as the "Green Project ." 2 Rong l solar systems that make up the solar hot water system consists of solar collectors , storage tanks thermoelectric solar stations , pipelines four parts. Solar collectors are produced by the company's patented technology superconducting heat pipe solar collector tubes and the union is a combination of high thermal efficiency ; all-glass vacuum tube collector solar absorptance greater than 0.94 , when the illumination of solar radiation 800 W / sq m ( ie, spring and autumn when the weather is fine ) , single collector tube that can be put in 2.5 hours at room temperature tube water heated to 90 ℃ ( by ambient temperature has little effect ) . Thermal storage tank can be enamel interior , insulation with efficient insulation material made of polyurethane foam , which greatly improves the thermal storage tank insulation performance and service life , thus ensuring a solar hot water system at minus 50 ℃ can still be used as usual. Pipe choice is high corrosion resistance , good heat resistance PPR pipe , pipe making good use of effects and longer service life . 3 Rong l Solar System Works 1 . Fourth-generation collector solar collector - superconducting heat pipe solar collectors, convert sunlight into heat . 2 . Collector temperature probe temperature TC at the tank outlet temperature is higher than the circulating loop TR a set value, the controller starts the circulation pump is running . 3 . The working fluid circulation pump to circulate in the circulation line . 4 . Rong l solar solar collectors through a heat exchanger to transfer heat to the collected heat storage tank . 5 . Rong l Solar circulation pump in operation, when the temperature difference is less than a set value, the circulation pump will stop working. 6 . Rong liter solar water temperature TR when the water temperature reaches the set maximum, the controller turns off the circulation pump . 7 . Rong liter solar water tank electric auxiliary heater tank top can automatically maintain a constant temperature setpoint. 4 Features 1 . Collector and storage tank separation , the whole pressure to run . 2 . Solar controller using artificial intelligence , automatic and reliable operation. 3 . Tank insulation can be placed anywhere in the room . 4 . Superconducting heat pipe solar collectors, double-loop systems , plumbing , seasonal use . 5 . Metal superconducting heat pipe collector , vacuum tube water minus 50 degrees in the north as usual heating, never bombing . 6 . The United States AO Smith Kim Kyu-liner solar heating tanks, pressure to run , easy to use . 7 . Constant temperature water, the maximum temperature setting , electric heating thermostat timer , set the data off memory protection , 24- hour hot water . 8 . Rong l solar split design , elegant appearance. 9 . Collectors can be mounted on the balcony , south wall , sloping roof , canopy, sloping roofs and other locations, arbitrarily placed . 10 . Rong l solar modular , building-block assembly, easy transportation and installation , truly and building integration . 4 main components of the system features 1 . Collector : Adopt Rong liter vacuum tube collectors . 2 . Electric Tank: U.S. AO Smith Kim Kyu-liner electric storage tanks, inner shell with a unique buckle craft , solid structure , beautiful appearance. 3 . Circulation pump : Germany WILO Wilo pumps, ensure that the system low power, low noise, long life . 4 . Collector and electric water carriers . 5 . Controller: imported from Germany , stable performance, complete functions. 6 . Workstation: the main components using imported Italian components to ensure safe and reliable operation of the closed system . 7 . Pipeline : We recommend using copper . 8 . Insulation Materials : 50-60mm imported polyurethane foam, insulation and lasting.
