Description
Technical field
The present invention relates to heat reservoir field, specifically refer to a kind of novel electric heat reservoir.
Background technology
Using clean energy resource is to improve city atmospheric environment, an importance of minimizing pollution for warm supplying hot water.China's the most commonly used coal-burning boiler in city is as heating boiler at present, and it is the most serious to the pollution of air.Although and use fuel oil, combustion gas or general boilers heated electrically can reduce atmospheric pollution level, single heating operation costly, is not suitable for promoting the use of.And in recent years, China's power consumption on daytime increases year by year, increase peak-trough electricity poor.Poor in order to reduce peak-trough electricity, electricity management department has formulated the preferential policy utilizing paddy electricity, and the electricity charge of fall trough-electricity are to encourage user's late night to morning electricity consumption.Thus if able to there is applicable energy storage electric boiler, trough-electricity is stored by certain way, use by day, cost of use will be substantially reduced.The most domestic energy storage electric boiler main atmospheric water tank to be had split type energy storage electric boiler, water tank type energy storage electric boiler with pressure, to aoxidize the iron-based solid electric heater as heat accumulating, energy storage device with solid-liquid phase change material as energy storage material, but because water at atmospheric pressure and band setting-out need relatively large water tank because thermal capacity is less, oxidation iron-based solid intensity difference, solid-liquid phase change material is expensive, long-term behaviour is unstable and some has relatively severe corrosive etc., and these devices all can not meet practice well；And traditional heat reservoir can not meet user and the most freely switch between heating and hot water taking.
Summary of the invention
It is an object of the invention to provide a kind of electric heat reservoir that can meet the high thermal efficiency that user freely switches between heating and hot water taking.
The present invention is achieved through the following technical solutions: include thermal storage device, heater, internal circulation system and external circulating system；Described internal circulation system is sequentially connected with heat collector by internal recycle pipeline, A heat exchanger, secondary circulation system and controller Guan Bi form；Described secondary circulation system is sequentially connected with fluid reservoir by internal recycle pipeline, interior water circulating pump forms with B heat exchanger Guan Bi；Described external circulating system is sequentially connected with A heat exchanger by outer circulation pipeline, custom system, outer circulation water pump and B heat exchanger Guan Bi form；It is characterized in that: described custom system includes radiator and faucet；Described faucet is that single-grip double valve combined tap, two valve size and action situation are completely the same；One valve inlet of faucet is connected to external pipe, exports as intake；Another valve inlet connects water supply line, and outlet is connected between radiator and outer circulation water pump.
By unique single-grip double valve combined tap, control water inlet and the outlet of external circulating system, then, when not fetching water, the water in water supply line also cannot be introduced in external circulating system simultaneously, the water supply capable of circulation heating installation that outer circulation pipeline Central Plains has, and when water intaking, the water in external pipe enters in external circulating system, water withdrawal is identical with output, the water quantity holding in external circulating system is made to balance, so, after stopping water intaking, the same supply heating installation capable of circulation of water in outer circulation pipeline.
Described controller is the intelligent controller of Automatic Control, the maximum temperature of thermal storage device, heat time heating time and exit water temperature can be automatically controlled, and the temperature of the time that need to be able to heat according to Different climate and user and temperature or water supply and Flow-rate adjustment heating load, unmanned can be realized；Described A heat exchanger is high-performance heat exchanger, it is possible to be rapidly completed heat exchange.
In order to the present invention is better achieved, further, radiator is switched over by three-way valve with faucet, and described three-way valve is one-in-and-two-out formula structure, and its import is connected to A heat exchanger by external pipe.
In order to the present invention is better achieved, further, water softening device is installed before the valve of described water tap connection water supply line or after valve；Described water softening device uses water flow switch to be controlled.
Employing water flow switch is controlled, and when there being water to pass through, water softening device starts automatically, when anhydrous by time, water softening device is automatically stopped.
In order to the present invention is better achieved, further, described custom system comprises one or more radiator, uses mode in parallel or series to connect between each radiator；Described custom system comprises any number of faucet, and between each faucet, mode connects in parallel.
In order to the present invention is better achieved, further, described external circulating system comprises one or more custom system, uses parallel way to connect between each custom system.
