Description
Technical field
The present invention relates to a kind of water tank, especially for the efficient water tank of Teat pump boiler.
Background technology
For some water demands bigger family or commercial location, the direct heating water system of heat pump water heater often can't meet the demands, thereby need the outfit water tank to come stored hot water, existing cisten mechanism mainly comprises shell, heat-insulation layer and inner bag, water tank bottom is provided with delivery port, the top is provided with water inlet, the outside is connected with the heat exchanger and the water circulating pump of Teat pump boiler in turn, water directly is stored in the big capacity inner bag, this water tank has the following disadvantages with the supporting use of heat pump the time: efficiency is low, during water when needs heat in the water tank, utilize circulating pump to draw water from water tank bottom, behind over-heat-exchanger, be back to water tank from the top again, with cold water mix a large amount of in the water tank, so circulation, mix, cause the temperature rise speed of water in the water tank extremely slow; On the other hand; owing to adopt heat pump; when the temperature of water in the water tank slowly is promoted near set water temperature; the water temperature that enters heat exchanger this moment is higher; the compressor return air temperature of heat pump also becomes than higher; thereby cause heat pump the situation of frequent shutdown to occur; its efficiency also descends significantly; its cardinal principle is because the compressor air suction temperature not only can not be too small, nor can be too high, need be a suitable temperature range; the Energy Efficiency Ratio of heat pump (cop value) is just more reasonable; the tradition storage tank is big owing to volume, and temperature gradient is little, thereby heat pump is produced bigger harmful effect.
Summary of the invention
In order to overcome the deficiencies in the prior art, the invention provides a kind of rational in infrastructure, efficiency is high, temperature gradient is high, heat time heating time is short efficient water tank that is used for Teat pump boiler.
The technical solution adopted in the present invention is:
The efficient water tank that is used for Teat pump boiler, comprise shell, heat-insulation layer and inner bag, the overlapping from top to bottom multilayer current unit that is placed with of described inner bag, described current unit comprises the elongated flute profile water stream channel of surrounding edge and surrounding edge inside, the water stream channel end of every layer of current unit is provided with the perforate that is communicated with lower floor current unit head end, the water stream channel head end of current unit, top is provided with the upper shed that is connected with external equipment, the water stream channel end of bottom water flow unit is provided with the under shed that is connected with external equipment, and this external equipment comprises the heat exchanger and the water circulating pump of Teat pump boiler.
Further improvement of the present invention, described inner bag, current unit all are circular, and described water stream channel is for being arranged in parallel, the adjacent parallel passage therein one interconnect.
Further improvement of the present invention, but described water circulating pump is the circulating pump of rotating work.
Further improvement of the present invention, described current unit is the plastic cement moulding, the bottom of current unit is provided with draw-in groove at the lug place corresponding to lower floor's flute profile water stream channel.
The invention has the beneficial effects as follows: the overlapping from top to bottom multilayer current unit that is placed with of inner bag, each inside, current unit is elongated flute profile water stream channel, make whole inner water tank form the water stream channel of one-way flow, when the water in the water tank need heat, owing to be unidirectional circulation canal, at first heated water is entering the inner bag from another opening, cold water is then corresponding to flow away forward, thereby avoided the mixing of cold water and hot water in the water tank, can keep higher temperature to circulate once more is heated, therefore, the temperature gradient of water is bigger in each circulation, realizes the purpose of Fast Heating; In like manner, because temperature gradient is big, reach design temperature very soon, shortened the poor efficiency heat time heating time of heat exchanger between the high-temperature region, improved the Energy Efficiency Ratio of heat pump, improve the operating condition of heat pump, also can not cause the situation that heat pump frequently stops, starts shooting simultaneously, further reduced energy consumption.
Description of drawings
The present invention is further described below in conjunction with drawings and Examples.
Fig. 1 is a structural representation of the present invention;
Fig. 2 is the decomposition chart of water tank;
Fig. 3 is position, the A place enlarged drawing of Fig. 1;
Fig. 4 is the vertical view of current unit.
The specific embodiment
Referring to figs. 1 through shown in Figure 4, the efficient water tank that is used for Teat pump boiler, comprise shell 1, heat-insulation layer 2 and inner bag 3, the overlapping from top to bottom multilayer current unit 4 that is placed with of inner bag 3, current unit 4 comprises the elongated flute profile water stream channel 42 of surrounding edge 41 and surrounding edge 41 inside, water stream channel 42 ends of every layer of current unit 4 are provided with the perforate 43 that is communicated with lower floor current unit 4 head ends, the water stream channel head end of current unit, top 4 is provided with the upper shed 44 that is connected with external equipment, water stream channel 42 ends of bottom water flow unit 4 are provided with the under shed 45 that is connected with external equipment, this external equipment comprises the heat exchanger 5 and the water circulating pump 6 of Teat pump boiler, design to water stream channel 42 sectional areas can be the area of section that equals or be a bit larger tham the external equipment pipeline, its objective is and guarantee the ducted mobile unanimity of water as far as possible in each stage, before the realization, back overall flow, effectively reduce heat time heating time, improve the efficiency of equipment.
The bottom of current unit 4 is provided with draw-in groove 46 at lug 47 places corresponding to lower floor's flute profile water stream channel 42, when assembling, upper strata current unit card groove just cooperates with the lug 47 of lower floor flute profile water stream channel 42 and clamps, seal, prevent that the current between the adjacent channels from interfering with each other, seepage.
In addition, water stream channel 42 also can be designed to spirality, S shape or arrangement such as three-back-shaped.
Further, but water circulating pump 6 adopts the circulating pump of rotating work, and when practical application, the user both can select the water (flow) direction of water tank to enter the top from the bottom to go out, also can enter the bottom from the top and go out, according to different behaviours in service and the switchover operation direction gets final product.Such as, little when urban water demand, think when using the inner water storage of water tank enough, just do not need from outside injection cold water, in order to guarantee to consume the heating still capable of circulation of a certain amount of hot water rear water box, can switch to water circulating pump 6 from the bottom this moment draws water, from the top entry.But because hot water outlet for people to use generally designs at low level, as be installed on the external pipe of under shed 45, under the prerequisite of the water yield abundance in water tank, water circulating pump 6 can be switched to from upper shed 44 and draw water, from under shed 45 entry, can guarantee so directly to use better effects if for the user from the hot water that heat exchanger comes out.Certainly, also the constant top water outlet oral-lateral of being located at heat exchanger of user's intake can be utilized water circulating pump 6 to force to supply water and reaches the purpose that can reach same, only need this moment to adopt unidirectional water pump to get final product.
More convenient in order to safeguard, the bottom of inner bag 3 is provided with sewage draining exit 7.
Certainly, the present invention is not limited to the above embodiments, is equal to the present invention or the similar techniques scheme also should belong within protection scope of the present invention.
