Description
Technical field
The present invention relates to a kind of solar water heating system, especially a kind of automatic loading water Intelligent emptying solar water heating system.This system energy automatic loading water, automatically cuts off the water supply, prevents spilling water, and the water in upper and lower conduit road can be discharged automatically in the winter time, prevent pipe freezeup after the water tank filling up water of solar water heater.
Background technology
Current solar energy develops, because water is cumbersome on manual operation water tank, sometimes forget also at Shang Shui, water completely rear nobody go to stop upper water will waste a lot of power and water, also can freeze the pipeline leading to solar energy hot water tank indoor winter, normally solar energy can not be used in winter, upper water instrument and exhaust-valve device are easy to bad at present, actuation time is long, power consumption is many, service life is short, current exhaust-valve can not control automatic loading water, can't filling up water automatic stop from emptying, without forgetting the problem that operation is emptying after hot water, will cause normally can not use solar energy winter, the bottom that above emptying valve is arranged on boiler is often subject to the heat transfer of boiler and the dirt of water thus reduces the service life of valve, above problem can not get solving, solar water heater is developed slow.
For many years, we scientific worker numerous in the industry has also made unremitting effort for this reason.Market there is in succession multiple tube emptying device, exhaust-valve, and concluded and substantially can be divided into 4 kinds:
The first is top ability of swimming exhaust method: need two-tube layout, a upper cold water pipe, a lower hot-water line.Implement upper water by combination tap, to discharge water and emptying.Method is: when using water, and running water moves to water tank, and in water tank, hot water overflows from an other end high position, descending along hot-water line.When stopping using water, stir faucet handle and stop upper water.Meanwhile, be positioned at the exhaust outlet at water tank two ends simultaneously to cold water pipe, hot-water line air inlet, hot water or cold water is naturally descending to be drained from tap.Advantage is: 1. fully take into account the custom that people use tap, and always full water state wind resistance is good for water tank simultaneously; 2. attic user uses this method more satisfactory; 3. not electricity consumption, safety.Shortcoming is: 1. just cannot use without running water; 2., when water temperature is not high, when winter is at every turn in order to push up the cold-water reflux of pressing, easily cause waste; 3. multiple spot uses inconvenient, when using water, should artificially note cutting off electrical heating power supply simultaneously;
The second is building waste heat freeze proofing: install near air draft well by water heater, allow indoor waste hot gas upwards discharge with pipe outer wall in muff, anti-antipriming pipe freezes, block up.Advantage is without power supply, cut down expenses, simple, this method of user near air draft well is ideal.Shortcoming, and unresolved pipeline thermal water waste problem, will note ensureing that indoor exhaust is unimpeded simultaneously.Still undesirable from the water heater away from air draft well.
The third is manually operated siphon-type exhaust method: install downcomer and each one of air inlet pipe, each one of water supply valve, discharging valve and intake valve.When using water, a little to water on water tank again after closing intake valve and discharging valve, then close water supply valve, open discharging valve, hot water from water tank upper sucking-off, flows to indoor by thermal water utilization siphon principle.The not used time, open intake valve air inlet, destroy siphon, in pipe, hot water is discharged to use and is reached the antifreeze object of blank pipe.Its advantage is: valve body is not easily for incrustation scale pollutes (only contacting with air), so performance is relatively stable; Not Electrical Safety; Overcome the curved gas of interior conduit " U " type to block up.Shortcoming is: cannot support the use with automatic upbound controller.But this original operation is too loaded down with trivial details, the automation requirement of modern cannot be adapted to, cannot popularize.
4th kind is water falling type exhaust method: outdoor exhaust-valve is by the turnover of small machine valve or solenoid control hot and cold water.Button makes magnetic valve open, and can realize water and discharge water.Stop use water, button valve-off, simultaneously INO air inlet, in water pipe, hot water can fully be utilized.Its advantage is: can save in upper and lower conduit in a large number and be detained hot water; Anti-antipriming pipe frozen block in winter; Facilitate supporting various type, use also more convenient; Price is relatively cheap.If only do emptying use, a set of need five or six ten yuan.Shortcoming: because control valve is positioned at the bottom of water tank, very easily pollutes by incrustation scale thus causes control malfunctioning, poor reliability; Again because valve body often stays water, outside needing winter, power up Insulation.Run into user indoor to have during " U " type curved pipe and cannot use; Water cannot be gone up during power failure and discharge water; Emptyingly frozen block will be there is with forgetting after hot water or upper water.This is a kind of emptying device more common on the market, is also the more a kind of emptying device of defect.
Make a general survey of above 4 class exhaust-valves, be not difficult to find out the minimum problem that should be taken into account the following aspects of a kind of good anti-freezing economical technical products: 1. reliability: valve body and probe all need scale-deposit-preventing to pollute; How to prevent valve body and water-level probe not by the pollution (it is transducing signal distortion that incrustation scale pollutes, control malfunctioning main cause) of incrustation scale; How to prevent from again burning out probe at water heater air drying high temperature, cause instrument malfunction.2. versatility: the general matching of different user condition; How to adapt to the hot water drop height of different user; Indoor " U " type curved pipe is arranged; Adapt to the spare interface of different brands water heater, and house hydraulic pressure is low and the supporting demand of the special user such as Timing water supply.3. convenience: how to adapt to such as: multiple spot uses the demand of hot water; After how preventing user from forgetting emptying or automatic loading water, winter also can not affect use, ensures that user's tap of fetching boiling water just has hot water.4. the property taken into account: allow water heater become point-and-shoot is as far as possible good beautiful with electric heater ratio.5. economies: how to allow user easily use button, the least possible waste hot water and cold water.Accomplish upper and lower conduit both without delay hot water waste, again can blank pipe antifreeze.Thus reach the object of cost investment and the insulation electricity charge of saving heating tape.
