Description
technical field:
The utility model relates to a kind of solar water heater, particularly relates to a kind of quick-heating type solar water heater.
background technology:
At present, solar water heater comprises solar heat collector, storage tank, heat exchange coil, circulation line and water circulating pump etc.After solar heat collector absorbs sunshine, the heat transfer medium in solar heat collector, by heat temperature raising, is passed through the action flow of water circulating pump in heat exchange coil by the heat transfer medium of heat temperature raising, thus is heated by the water of storage tank bottom; Storage tank bottom automatically rise to top, and the cold water on storage tank top sinks to bottom automatically after being raised by the coolant-temperature gage heated.So constantly, through nearly darg, the water in storage tank progressively all heats by solar energy.When solar energy during the not enough and temperature that the water temperature on storage tank top is lower than setting, superposed electrical heating starts automatically, the water on storage tank top is heated to the temperature of needs.In order to realize whole day 24 hours hot water, the electrical heating on storage tank top is in state on duty usually always, when storage tank top water temperature is lower than the temperature set, electrical heating starts automatically, until just automatically stop after storage tank top water temperature is heated to the temperature of setting.This system is relatively simple, advantage of lower cost.But there are two disadvantages:
First disadvantage is: when continuously overcast and rainy there is no a solar energy heating time, only have storage tank top to have hot water, and bottom is cold water.User at night or morning concentrate in large quantities use hot water time, just there is the under-supply problem of hot water.When there is no hot water, must long time be waited for, water could be heated (assuming that electrical heating power is 2KW, 80 kg of water being heated to 45 DEG C of needs heating about 1 and a half hours from 15 DEG C).This is obviously inconvenient concerning user.
Second disadvantage is: in order to improve exchange capability of heat, heat exchange coil preferably adopts copper pipe, and currently, the liner material of water tank mostly is steel plate and is coated with high-temperature tubring outward, because enamel surfaces local exists micropore, therefore just likely form electrochemical corrosion between copper-iron-water, iron is anode, and copper is negative electrode.Due to the iron anode that very large cathode is very little to local, water tank local perforations therefore may be caused to leak.
utility model content:
Technical problem to be solved in the utility model is: overcome the deficiencies in the prior art, provide a kind of reasonable in design, the thermal efficiency is high, firing rate is fast and the quick-heating type solar water heater that can automatically control.
The technical solution of the utility model:
A kind of quick-heating type solar water heater, containing solar thermal collector and storage tank, the two is communicated with return pipe by hot-water line, top electric heater and bottom electric heater is respectively arranged with in the inner chamber of described storage tank, heat exchange coil is provided with in described storage tank, the top and bottom of described heat exchange coil are communicated with return pipe with described hot-water line respectively, described return pipe is provided with circulating pump, the hot water outlet of described solar thermal collector, the hot water outlet of storage tank, the middle part of storage tank is respectively arranged with temp probe, all temp probes are all connected with controller, described controller also respectively with circulating pump, top electric heater, bottom electric heater connects, described storage tank was connected with water consumption device by communicating pipe.
Described top electric heater and electric heater place, bottom are also respectively arranged with temp probe, and this temp probe is connected in series mutually with described top electric heater and bottom electric heater respectively.
The hot water exit of described solar thermal collector is provided with air bleeding valve; The upper end of described storage tank is provided with P/T valve.Described return pipe is also respectively arranged with prefill valve, Pressure gauge, expansion drum and relief valve.
The beneficial effects of the utility model:
1. respectively there is an electrical heating top and the bottom of the utility model storage tank, controller can determine whether to start bottom electrical heating according to storage tank bottom water temperature and the time on the same day automatically, thus guarantee setting-up time in the afternoon, water tank temperature of lower reaches the temperature of needs, thus avoids overcast and rainy hot water not enough and the problem that the stand-by period is long.
2. the utility model is in order to avoid bleeding off too much cold water (problem that water is not warm) during bathing, supplying hot water pipeline can also be designed to the circulatory system, during bathing when hot water pipeline temperature requires temperature lower than bathing, intelligent controller opens hot-water circulating pump automatically, force the water circulation in pipeline, ensure that pipe temperature reaches bathing requirement temperature all the time.
3. the timing in the Different periods of every day of the utility model controller detects storage tank temperature of lower, in section sometime, (as 10:00-11:00 in the morning) temperature does not reach design temperature, illustrate that solar energy is not enough or water consumption is excessive, to automatically start bottom electrical heating, automatically stop again after making it reach design temperature.Make its underpart water temperature (as in) in official hour reach the final temperature (this temperature can set arbitrarily on the controller) needed, this system can fully demonstrate and preferentially utilize solar energy source the 6:00 water use peak phase in the afternoon.
4. the utility model is reasonable in design, the thermal efficiency is high, firing rate is fast and can automatically control, applied widely, has good economic benefit after popularization.
