Description
Technical field
The utility model relates to a kind of water heater, and more particularly, the utility model relates to a kind of auxiliary electrical heating solar water heater.
Background technology
Solar water heater is the major product that solar thermal energy utilizes, and he utilizes the greenhouse principle to change the energy of the sun into heat energy, and transmits heat to water, thereby obtains hot water.But be subjected to climatic influences, the solar water appliance has tangible limitation, winter-spring season or meet a run of wet weather weather, the electricity consumption of having to is heated, because the water storage tank capacity of solar water heater is all bigger, not only the electric energy that is consumed is higher than electric heater, and the hot water easier waste that causes of toing many or too much for use.At present, still there is not mature technique to solve this problem.
Obtain the domestic water with uniform temperature by electrical heating, convenient because of it, cleaning, environmental protection have become a kind of common living electric apparatus.For energy-conservation, reduce the consumption of electric energy, people attempt adopting heat pump techniques.But existing heat pump techniques because equipment is complicated, invest higher, particularly can't miniaturization, therefore, be difficult in living electric apparatus, use.
Zeolite molecular sieve has unique absorption property, and for the heat pump effect of zeolite molecular sieve in desorption, adsorption process, people entertain very big interest always, wishes to replace traditional compression type heat pumping system with this.But, because desorption, sorption cycle not only need higher heating-up temperature, and need constantly heat up and lower the temperature and could realize circulation, therefore, be difficult to form effectively continuous the circulation, also there is not the product of practicability to move towards market at present.
Summary of the invention
Goal of the invention: the purpose that the utility model is is to overcome the deficiencies in the prior art, and a kind of auxiliary electrical heating solar water heater of significantly saves energy is provided.

Description of drawings
Be illustrated as structural representation of the present utility model.
The specific embodiment:
As shown in drawings, auxiliary electrical heating solar water heater of the present utility model comprises water storage tank 17 and control circuit 20, and water storage tank 17 is separated plate 14 and is divided into heating water tank 16 and low-temperature heat source water tank 13.Intercommunicating pore 18 is arranged on the demarcation strip 14, and the port that intercommunicating pore 18 is positioned at heating water tank 16 is provided with intercommunicating pore cover plate 19.The upper plate of heating water tank 16 is equipped with adsorbent bed 1.Described adsorbent bed 1 comprises housing, is provided with woven wire 2 in inner walls, is filled with adsorbent 3 in the woven wire 2, is provided with electrothermal tube 4 in the adsorbent 3, and described adsorbent 3 is a zeolite molecular sieve; The upper/lower terminal of housing clamps with pressing plate 5, and pressing plate is provided with mass transfer groove and aperture.。Housing top is provided with desorption mouth 8 and adsorption orifice 9, is connected with desorption pipe 6 on the desorption mouth 8, and desorption pipe 6 is provided with pressure valve 7; Adsorption orifice 9 with pass the adsorption tube 10 that demarcation strip 14 stretches in the gas-phase space on low-temperature heat source water tank 13 tops and be connected, the adsorption tube 10 that is positioned at low-temperature heat source water tank 13 is provided with magnetic valve 11.Low-temperature heat source water tank 13 is provided with water inlet pipe 12 and outlet pipe 15, and heating water tank 16 is provided with outlet pipe 15.
When weather condition was bad, the solar heat that receives by solar thermal collector can't make the water in the water storage tank 17 reach satisfied serviceability temperature, at this moment can carry out electrical heating with assisted heating device to the water conservancy in the heating water tank 16.During powered-down switch 21, control circuit 20 enters and regularly heats control model.Electrothermal tube 4 in the adsorbent bed 1 enters heated condition, and at this moment, magnetic valve 11 cuts out adsorption orifice 9; Adsorbent bed 1 is through electrical heating, and temperature raises gradually, and the hydrone that has been adsorbed agent 3 absorption obtains energy, and desorption comes out from adsorbent 3 gradually.Along with the rising of gas pressure in the adsorbent bed 1, pressure valve 7 is opened, and desorption steam flows out through desorption pipe 6 by desorption mouth 8, by the heat transfer water of condensation heat in heating water tank 16.Along with the rising of adsorbent bed 1 temperature, adsorbent bed 1 carries out heat exchange by container wall and water simultaneously.Because the existence of heat transfer resistance constantly heats up the adsorbent 3 in the adsorbent bed 1, and can meet the requirements of desorption temperature in the time of setting, finish desorption process.
When electrical heating reached the time of setting, under the control of control circuit 20, electrothermal tube 4 deenergizations in the adsorbent bed 1 stopped heating.At this moment, the magnetic valve 11 on the adsorbent bed 1 is deenergization simultaneously, and adsorption orifice 9 is in opening.After stopping heating, adsorbent bed 1 still is in the condition of high temperature, and continuation and water carry out heat exchange.Along with adsorbent bed 1 temperature reduces gradually, the adsorption capacity of adsorbent 3 improves gradually, through the continuous water vapours of absorption low-temperature heat source water tank 13 gas-phase spaces of adsorption tube 10, and emits heat of adsorption at heating water tank 16 by adsorption orifice 9.The heat of adsorption of emitting continues to carry out heat exchange by the water in the wall of adsorbent bed 1 and the heating water tank 16, and water constantly heats up in the process of adsorbent bed 1 cooling.Because the special high temperature absorption property of zeolite molecular sieve, in this process, realized combination and the coupling of water to the temperature-rise period of the cooling of adsorbent bed 1 and water.Under the suction-operated of adsorbent bed 1, the water in the low-temperature heat source water tank 13 constantly evaporates, and the heat of vaporization that evaporation process absorbs reduces the water temperature in the low-temperature heat source water tank 13.On the other hand, under the effect of solar thermal collector, the water in the low-temperature heat source water tank 13 constantly absorbs the heat of solar energy, and water temperature is raise, and makes solar energy become the indirect low-temperature heat source of operation of heat pump thus.If night all the time according to the time because low-temperature heat source water tank 13 generally has enough water amounts,, also enough satisfy the requirement of adsorption process by absorbing solar energy with the heat that the water temperature form stores.
The above only is a preferred implementation of the present utility model; should be pointed out that for those skilled in the art, under the prerequisite that does not break away from the utility model principle; can also make some improvements and modifications, these improvements and modifications also should be considered as protection domain of the present utility model.
