Abstract
An air pump water heater comprises an inner container upper end socket, an inner container, an inner container lower end socket, a water outlet channel and a water inlet channel. A separation blade is arranged at the output end of the water inlet channel and is communicated with the inner container through a water outlet gap, and a coil pipe is arranged above the separation blade. By means of an inner container water tank designed in the water heater, when hot water in the tank is used, newly injected cold water upwards pushes the hot water to move forward basically in a piston flow mode, the water mixing phenomenon in various flow modes such as laminar flow and transition flow formed due to water column impact and convection generated due to temperature differences is reduced as much as possible, the made hot water can be pushed out of the inner container for use to the largest extent, and the water outlet rate of the water tank is increased to the maximum. Compared with the a common inner container, the water outlet rate of the inner container water tank is increased to over 96% from about 72%, and heating efficiency of the coil pipe is high.
Description
Technical field
The present invention relates to emergency water storage tank, be specifically related to a kind of air pump water heater.
Background technology
At present, water tank, adopts the vertical inner bag water tank of drum-shaped vertical bearing, mostly by inner bag upper cover; Inner bag; Inner bag low head; Outlet pipe (mouth); The compositions such as oral siphon (mouth).After heat pump prepares hot water, open radiator drain stop valve when user uses, by the pressure of water route pipe network, cold water is injected inner bag from water inlet, and hot water is extruded inner bag for user from outlet pipe.
Because cold water injection is rear and inner bag hot water is mutually mixed thus the reason of reduction coolant-temperature gage, after the hot water of one case design temperature approximately can only use the hot water of its 72% (i.e. water rate) left and right volume just Yin Wendu drop to lower than user cannot continue with hot temperature degree (as 43 DEG C) use (non-serviceable heat claims after-heat), again can only heat after intensification until heat pump and reuse.
The actual volume of Here it is current heat pump water box inner bag must be over the reason with water capacity nearly 1/3.This situation brings following problems: (1) because of mass storage hot water preserving heat and radiating heat loss cause energy waste, systematic energy efficiency ratio is low; (2) water tank small product size is huge, takies user's space large; (3) water tank manufacturing cost is high; (4) time of preparing one case hot water is long; (5) in water tank, the isoionic activity of chlorine residue in running water is accelerated in the temperature rise of abundant residues heat, thus accelerates the corrosion of inner water tank, causes leaking outside in system fault, even causes whole equipment scrapping.
The condensing heat exchanger of such version, because coil pipe total length is longer, general nearly tens of rice (more than 30 meters), causes whole coil pipe height higher, close to inner bag height about 70%.This tactic pattern causes two problems.
One be when system be in water tank without the static heating process of Inlet and outlet water in time, whole inner bag top and the bottom water temperature is in even propradation substantially, and the upper current downflow caused because of the temperature difference is little.According to heat pump principle, after cold hot-side temperature is determined, the efficiency (Energy Efficiency Ratio COP) of heat pump depends on the surface coefficient of heat transfer of heat exchanger, and the cold warm end temperature difference that this coefficient causes along with water temperature rises reduces and reduces.So the condensing heat exchanger of this version its efficiency in a quiescent operation process reduces gradually.
Two is use in hot water process when system is in user, when existing in the dynamic heat process of Inlet and outlet water, cause because system effectiveness is lower and fail to prepare the hot water that user requires temperature in time, cause the indifferent of systems stay hot-water supply, namely water tank water rate is low.
Cause the reason of the problems referred to above to be that, due to relative inner bag internal diameter, cold water water inlet bore is too little, after cold water injects inner bag with larger flow velocity, Reynolds number is less, thus with laminar flow state flowing in inner bag, increases the degree that hot and cold water mixes mutually.
Therefore, for existing problems of the prior art, the technology needing the air pump water heater providing a kind of heating efficiency high badly seems particularly important.

A kind of air pump water heater, as Fig. 2, Fig. 3 comprise the coil pipe be arranged in inner bag 5, described coil pipe is that multilayer is formed by heat exchanger tube along the radial level winding of inner bag, described heat exchanger tube is provided with working medium entrance and sender property outlet, described working medium entrance is arranged at outermost layer, described sender property outlet is arranged at innermost layer, and described heat exchanger tube is set to the multilayer threaded coiler of coiling from outside to inside.
In order to reduce coil pipe whole height to greatest extent, under the limiting parameter condition such as inner bag internal diameter D, coil pipe total length L, coil pipe outer diameter D p, innermost layer spiral internal diameter Di, helix pitch Dc, interlamellar spacing Dl, the method for designing of the maximum numbers of plies can arranged in employing inner bag 5 internal diameter D calculates total number of plies Lmax, every layer of benchmark number of turns C and can be each layer number of turns of C, (C+1) or (C-1) by optimizing and revising rear value.
In coil pipe manufacturing process, after pipe positioning winding is formed ground floor coil pipe, positioning winding second layer coil pipe on this ground floor coil pipe, second layer coil pipe is made to be entrenched in the recess between the pipe of above-mentioned ground floor coil pipe outer surface with interlamellar spacing Dl, after, same method, at second layer coil pipe upper surface, positioning winding third layer coil pipe, third layer coil pipe upper surface positioning winding the 4th layer of coil pipe and form multilayer coil pipe.Wherein, the coil winding direction of odd, even several layers is identical, trend is contrary.The coil pipe designed like this make use of inner bag radial space as much as possible, and is down to minimum by coil pipe height.
Concrete, the heat exchanger tube of any layer is embedded at the recess of the interlamellar spacing of adjacent one deck heat exchanger tube.
Adopt aforesaid way to use heat exchanger tube coiling farthest can increase the surface area of heat exchanger tube for coil pipe, reduce the height of coil pipe simultaneously.
The winding direction of the heat exchanger tube of odd-level is identical with the winding direction of the heat exchanger tube of even level.
The winding direction of the heat exchanger tube of odd-level is contrary with the trend of the winding direction of the heat exchanger tube of even level.
Described heat exchanger tube is arranged at described inner bag bottom.
Wherein, described set of heat exchange tubes is made up of a heat exchanger tube winding.
During system works, the heat exchange of the feedwater side in condenser is limited in inner bag bottom short as far as possible a section (hypomere), causes this section of water temperature to rise as quickly as possible, thus forms the temperature difference large as far as possible with epimere water temperature.
The large temperature difference of inner bag upper-lower section water temperature accelerates the convection current of inner bag internal water, forms the reciprocal convection circulation that high-temperature water rises, water at low temperature declines.
This convection circulation process always with the mode of the maximum convection current temperature difference last till inner bag water be heated to design temperature after system stalls and terminating gradually.
For the condenser coil with identical total length, if it is highly lower when being positioned over bottom inner bag, with it by directly conduct heat exchange water less, water temperature rising faster, and then the temperature difference to be formed with the water on inner bag top is larger, causes the convection current up and down of inner bag water faster.In static heating process, always can ensure that the maximum condensation temperature difference is formed at inner bag bottom, thus the system that ensures is in the duty of peak efficiency.In dynamic heat process, the hot water on inner bag top is released use with given pace, heated rapidly by with the maximum condensation temperature difference after the cold water supplemented bottom inner bag enters inner bag with same speed, thus ensure that system effectiveness is the highest, heating capacity is the strongest, and then ensure that water tank water rate is the highest.
In addition, for more high-power heat pump, significantly increase coil pipe total length because condenser coil needs corresponding significantly increase heat exchange area, thus cause pipeline long and occur the problems such as heat exchange efficiency significantly reduces, pressure at expulsion increase, even causing difficult design.Each layer branch circuit parallel connection gets up by the method for shunting by multilayer coil pipe of the present invention, and the one way branch road of formation only has coil pipe total length part, thus can be divided into and effectively addressing this problem.
Finally should be noted that; above embodiment is only in order to illustrate technical scheme of the present invention but not limiting the scope of the invention; although be explained in detail the present invention with reference to preferred embodiment; those of ordinary skill in the art is to be understood that; can modify to technical scheme of the present invention or equivalent replacement, and not depart from essence and the scope of technical solution of the present invention.
