Description
Technical field
The present invention relates to a kind of solar water supply system based on the backflow water-saving technology, needing in Modern Family, the hotel to be particularly useful for the place of energy-saving and water-saving.
Background technology
At present, solar water heater is mainly by vacuum heat collection pipe, incubator, support, connecting pipe and composition of the control system.In the process of solar water heater development, existing considerable intelligent control instrument applies to wherein, as showing the water temperature water yield and duty, water-temperature water-level Set arbitrarily; Automatic loading water, dry combustion method is shone in air defense, safe self check, water completely reaches the lack of water automatic alarm; When the luminous energy of the sun can not satisfy the water temperature requirement, automatically start electric auxiliary heating; Outdoor pipe automatic freezing-protective function; Unusual automatic alarm, creepage protection function etc.When affirming these system advantages, water resource waste problem and leaving water temperature instability problem when ubiquity is debugged water temperature again.
Summary of the invention
When overcoming existing solar water heater debugging water temperature waste water resource and mix up water temperature after the leaving water temperature instability problem can appear, the invention provides a kind of solar water supply system based on the backflow water-saving technology.Native system has been realized the water that does not reach design temperature of solar water heater output is entered the backflow storage tank by return valve through reflux line by controller, waits for recycling, has reached water-saving.In addition, the size of regulating the digital electronic valve by controller realizes the adjusting of hot and cold water water outlet proportion, makes leaving water temperature and flow keep substantially constant.
The technical solution adopted for the present invention to solve the technical problems is: a kind of solar water supply system based on technique of backflow mainly is comprised of water tank for water-heater, vacuum heat collection pipe, backflow storage tank and controller.Wherein, controller is comprised of processor of single chip computer, temperature sensor, temperature detecting module, flow sensor, digital electronic valve, switch control module, Keyboard Control module, LCD demonstration and power module.The solar water supply System Working Principle: at first, open the storage tank entering water electromagnetic valve, backflow Water inlet valve for water storage tank door is closed, make cold water flow to storage tank, reach the setting liquid level, entering water electromagnetic valve is closed, and the vacuum heat collection pipe of solar water heater heats cold water.When the needs water, press " ON/OFF " button, flowing water Valve is closed, the recirculation water valve open, hot-water valve is transferred to maximum, Cold water tap is transferred to minimum, and this moment, the hot water outlet pipe inner cold water flowed into the backflow storage tank by reflux line, until the water temperature by outlet conduit reaches when setting leaving water temperature, flowing water Valve is opened, return valve is closed, and the cold/hot water regulating valve door makes water temperature and flow meet user's request according to setting leaving water temperature and the automatic adjusting size of water flow.When the backflow water storage tank water level was lower than minimum liquid level, backflow Water inlet valve for water storage tank door was opened, after the backflow water storage tank water level reaches medium liquid level, and autoshutdown.When the backflow water storage tank water level reached the highest liquid level, flowing water Valve was opened, and hot water was regulated electronic valve and closed this moment, until the backflow water storage tank water level drops to lowest water level.In the use procedure, water temperature and flow value that controller can be set with last time are deposited E
2Among the RAM, open switch after, controller can be regulated control to each valve by the water temperature that set last time and flow value.If change the temperature of water outlet, only need to press the temperature key, regulate again " ↑ ", " ↓ " key and can realize that temperature just regulates.If change the flow of water outlet, only need to press the flow key, adjusting " ↑ ", " ↓ " key can be realized the uninterrupted adjusting again.Automatically withdraw from the conciliation state after the adjusting.When the temperature of flowing water Valve place actual water temperature and setting was consistent, going out water solenoid valve can open automatically, and water just can flow out.By temperature sensor and flow sensor water temperature and flow are detected dynamic adjustments hot water or cold water valve in real time, realize water temperature and Flow-rate adjustment, and keep the water outlet of constant temperature constant.The leaving water temperature and the flow that arrange can be by showing by LCD.
The invention has the beneficial effects as follows, when the debugging water temperature, do not waste and make water, also realized the control of digitlization water temperature and Flow-rate adjustment, and by LCD display setting temperature and flow information, actual temperature and flow information, and additional timing heated, sleep, Beijing time Presentation Function.System is easy to use, saves water and energy Environmental Safety.
