Description of drawings
Accompanying drawing is a structural representation of the present utility model.
The specific embodiment:
Below in conjunction with accompanying drawing the utility model is done further explanation.
Solid adsorption type air source heat pump electric heater with 60L shown in the drawings is an example, and the inner bag 1 that it comprises control circuit 4 and has heat-insulation layer 2 is equipped with three adsorbent beds 16 on the base plate of inner bag 1.5%, three adsorbent bed 16 that adsorbent bed 16 shared volumes account for water storage tank inner bag volume is connected on the same control circuit 4.Adsorbent bed 16 comprises housing, and the inwall of housing is provided with layer of metal silk screen 15, and adsorbent 14 is housed in the woven wire 15, and adsorbent 14 is a zeolite molecular sieve, and electrothermal tube 13 is arranged in the middle of the zeolite molecular sieve.The upper/lower terminal of housing clamps with pressing plate 17.The upper plate of adsorbent bed 16 has desorption mouth 18, and desorption mouth 18 is connected with desorption pipe 20, and desorption pipe 20 is provided with pressure valve 19; The lower shoe of adsorbent bed 16 is provided with adsorption orifice 3, is connected with adsorption tube 7 on the adsorption orifice 3, and the part that adsorption tube 7 stretches out inner bag 1 is provided with magnetic valve 8.Adsorption tube 7 passes heat-insulation layer 2 and stretches in the cold bucket 9, and the end that is positioned at cold bucket of adsorption tube 7 is higher than the water surface of cold bucket 9.Cold bucket 9 is provided with cold bucket water inlet pipe 11, and an end of cold bucket water inlet pipe 11 is communicated with cold bucket water inlet 12 on the inner bag 1, and the other end of cold barrel 9 of being positioned at of cold barrel of water inlet pipe 11 is provided with ball float water level eliminator 10.Cold bucket 9 is carried out automatic water supplement, makes in the cold bucket 9 and remains certain water yield.
Connect power supplys by power line 6, closed power switch 5, control circuit 4 enters the heating control model, to the electrothermal tube 13 in each adsorbent bed 16 switch on successively heating and implementation timing controlled.Electrothermal tube 13 in first adsorbent bed 16 enters heated condition, and the magnetic valve 8 on this adsorbent bed adsorption tube 7 cuts out adsorption orifice 3.Adsorbent bed 16 is through electrical heating, and temperature constantly raises, make the hydrone that is adsorbed agent 14 absorption obtain energy gradually from adsorbent 14 desorption come out.Along with the rising of gas pressure in the adsorbent bed 16, pressure valve 19 is opened, and desorption steam is by the water to be heated of desorption pipe 20 in desorption mouth 18 enters inner bag 1, and water vapour is by the heat transfer water of condensation heat in inner bag 1.In this process, owing to there is the resistance of conducting heat between the wall of adsorbent bed 16 and the heated water, the adsorbent 14 in the adsorbent bed 16 is constantly heated up, and in the heat time heating time of setting, can meet the requirements of desorption temperature, finish desorption process.
When electrical heating reached design time, under the control of control circuit 4, electrothermal tube 13 deenergizations in first adsorbent bed 16 stopped heating, and the magnetic valve 8 in this adsorbent bed 16 on the adsorption tube 7 is deenergization simultaneously, and adsorption orifice 3 is in opening.Simultaneously, the electrothermal tube 13 in second adsorbent bed 16 enters heated condition.After electrothermal tube 13 in first adsorbent bed 16 stops heating, till the 3rd adsorbent bed 16 finished heating process, all be in cooling cooling and adsorbed state.After stopping heating, the adsorbent 14 in this adsorbent bed 16 still is in the condition of high temperature, by with inner bag 1 in be heated the heat exchange of water, the temperature of the adsorbent 14 in this adsorbent bed 16 reduces gradually, the adsorption capacity of adsorbent 14 improves gradually.Adsorbent 14 passes through the water vapours in the cold bucket 9 of adsorption tube 7 continuous absorption, and emits heat of adsorption.The heat of adsorption of emitting continues to be taken away in cooling procedure by the water in the inner bag 1, continues the water in the heating inner bag 1.Simultaneously, because the suction-operated of adsorbent bed 16 causes the water in the cold bucket 9 constantly to evaporate, the heat of vaporization that evaporation process absorbs reduces the water temperature in the cold bucket 9.Under the promotion of the temperature difference, the wall of cold bucket 9 constantly absorbs airborne heat, makes air become the low-temperature heat source of operation of heat pump.Owing to constantly evaporation, the water amount reduces gradually in the cold bucket 9, and is instant to 9 moisturizings of cold bucket through water inlet pipe 11 by cold bucket water inlet 12, and inflow makes the water level in the cold bucket 9 be in dynamic balance state by 10 controls of ball float water level eliminator.When the 3rd adsorbent bed finished heating process, first adsorbent bed was finished adsorption process, enters heated condition again, the next circulation of beginning.When the water in the inner bag 1 reaches the temperature spot of setting, under temperature sensor control, enter keeping warm mode.
Because the pondage of electric heater is generally all bigger, so the energy-saving effect of its heating process is just very considerable, economize on electricity can reach 30%.
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.
