Description
Technical Field
The invention relates to the technical field of solar water heaters, in particular to a solar water heater with a conducting liquid dispenser device and a using method thereof.
Background
Solar energy is a green and environment-friendly renewable energy source, and the way of installing and using solar water heaters in high-rise residences has been for decades. At present, a newly-built high-rise residence is a construction standard which must be met by installing a solar water heating system according to the requirements of relevant national departments. The solar water heater commonly used in the current high-rise building mainly has two application forms: the first is direct heating type, and the second is heat exchange type.
The direct heating type is that cold water in a pipeline of the heat collector is heated to an evaporation circulation state through a solar vacuum tube type heat collector, so that the cold water in a water storage tank on the heat collector is directly heated by solar energy, and hot water with a certain temperature is generated.
The heat exchange type is that heat transfer liquid stored in a heating pipeline of the outdoor wall-mounted heat collector is heated to a thermal expansion circulation state through a solar vacuum tube or a flat plate type wall-mounted heat collector, so that cold water in an indoor water storage tank is circularly heated and exchanged through a transfer liquid pipeline to generate hot water at a certain temperature.
The heat exchange type (secondary heating and indirect heating) solar water heater mainly adopts propylene glycol antifreeze fluid with the characteristics of high heat exchange efficiency, low-temperature antifreezing property, low toxicity and the like as a heat conduction working medium in a solar vacuum tube or a flat plate type heat collector pipeline, and is generally popularized and applied in high-rise civil residential buildings due to the characteristics of a working framework of split combination of an outdoor wall-mounted heat collector and an indoor water storage tank, convenience in installation, maintenance, use and the like.
Among the users who use heat exchange type solar water heaters in most high-rise houses at present, the common reflection of the heat exchange type solar water heaters installed in homes is as follows: the heating efficiency is low, the leakage is high, the maintenance cost is high, and the problems are mainly shown in the following two aspects:
1. some heat exchange type solar water heaters (such as wall-mounted type) have low heating efficiency even when the sunlight is fully irradiated, and the highest temperature of heating water is between forty degrees and fifty degrees;
2. when the heating efficiency of some heat exchange type solar water heaters (such as wall-mounted type) is high when the sunlight is fully irradiated, if the heat exchange type solar water heaters are not used for a few days, heat conduction liquid stored in a heating pipeline of an outdoor heat collector can be caused to be heated continuously to a thermal expansion state, the saturation pressure of the heat conduction liquid can be generated to expand and increase, and the liquid leakage phenomenon can be caused frequently to occur on a joint of the heating pipeline.
To deal with the above problems, the first solution for manufacturers of solar water heaters to solve the problems is to require users to replenish the conduction liquid in time; the second is to require the user to cover the outdoor collector with a sun cloth. The first solution is to maintain the leakage of the heating pipe joint at a low cost each time; the second solution is not only inconvenient to cover the sunshade cloth outside the high-rise window, but also the sunshade cloth is often scratched for a long time without encountering strong wind and rain, and once the sunshade cloth is forgotten to be covered and is not used for a long time, a certain solar water heater with high heat exchange efficiency and filled with the conduction liquid can lead the conduction liquid to accumulate to generate the phenomena of thermal saturation volume expansion and pressure increase, thus leading the conduction liquid pipeline to generate liquid leakage.
The basic structure of the working system of the heat exchange type solar water heater is shown in fig. 1. Fig. 9(a) -9 (b) are schematic diagrams of 3 liquid states of the conduction liquid in the secondary heat exchange type solar water heater, wherein fig. 9(a) is a condensed liquid state, fig. 9(b) is a saturated hot liquid state, and fig. 9(c) is an unsaturated hot liquid state.
Fig. 1 also shows a condensed liquid state diagram of the heat transfer fluid at room temperature stored in the tubes of the outdoor heat collector 200; FIG. 2 is a schematic view showing the circulation of the heat transfer fluid in a normal liquid state in the pipe, showing the circulation of the partially condensed liquid state + the partially saturated hot liquid state in the normal liquid state operation cycle under the expansion pressure of the heat transfer fluid stored in the pipe of the outdoor heat collector 200; fig. 3 is a schematic view showing the circulation of the heat transfer fluid in the pipe in a fully saturated liquid state, which shows the circulation of the heat transfer fluid stored in the pipe of the outdoor heat collector 200 in a fully saturated liquid state.
At present, most manufacturers of solar water heaters adopt an operation process of incomplete filling state as shown in fig. 4 for filled conducting liquid, especially for conducting liquid with high heat exchange efficiency such as propylene glycol, when installing heat exchange type solar water heaters for users. The operation of not filling the conducting liquid can make the outdoor heat collector 200 be in a cycle working state of unsaturated heat liquid state and low heat exchange efficiency when the outdoor heat collector 200 is exposed to the sun continuously by the solar energy, and the water heating temperature in the water tank of the solar water heater is limited below fifty degrees due to the cycle working condition of the unsaturated liquid state of the conducting liquid in the pipeline as shown in fig. 5, so that the phenomena of saturation pressure expansion increase and pipeline leakage caused by accumulated heating of the conducting liquid can not be generated. Although the operation mode ensures that the conducting liquid of the heat exchange type solar water heater cannot generate the phenomena of pipeline leakage or pipe explosion, the service quality of residents installing high-rise residents of the wall-mounted heat exchange type solar water heater is greatly influenced because the working state of high-efficiency heat exchange of solar energy cannot be realized, so that the market impression of customers such as low heating efficiency, no energy conservation, high maintenance cost and the like of the wall-mounted heat exchange type solar water heater is caused.

Detailed Description
It is to be understood that the following detailed description is exemplary and is intended to provide further explanation of the invention as claimed. Unless defined otherwise, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this invention belongs.
It is noted that the terminology used herein is for the purpose of describing particular embodiments only and is not intended to be limiting of exemplary embodiments according to the invention. As used herein, the singular forms "a", "an" and "the" are intended to include the plural forms as well, and it should be understood that when the terms "comprises" and/or "comprising" are used in this specification, they specify the presence of stated features, steps, operations, devices, components, and/or combinations thereof, unless the context clearly indicates otherwise.
The invention can improve the energy-saving efficiency and the use quality of the heat exchange type solar water heater product by referring to the working principle and the application method of the system structure when a person skilled in the art designs and manufactures the conduction liquid dispenser device and the application of the secondary heat exchange type solar water heater, and the specific implementation modes can be as follows:
example 1
The embodiment is a manual application mode of a liquid distributor device, and particularly, the existing heat exchange type solar water heater can be additionally installed and modified as long as the heat exchange type solar water heater uses a conducting liquid, regardless of any products such as a wall-mounted type and a direct-connected type. A liquid separating tank 100, a liquid separating valve 101, a one-way valve 102 and a liquid discharging valve 103 are integrated into a small-sized conducting liquid separator device which is arranged at the lower part of an indoor water tank, the separator pipelines of the liquid separating valve 101, the one-way valve 102 and the liquid discharging valve 103 are connected with the two ends of a conducting liquid inlet valve 301 in parallel, and the pipeline of an outdoor heat collector 200 is filled with conducting liquid, so that the working condition state with high heat exchange efficiency can be achieved.
Specifically, the liquid separating tank 100 is connected with a liquid inlet of a heat exchanger 400 arranged in the water tank 500 through a first pipeline, and a liquid separating valve 101 is arranged on the first pipeline; the liquid separating tank 100 is respectively connected with the outlet of the outdoor heat collector 200 through a second pipeline and a third pipeline which are connected in parallel, the second pipeline is provided with a one-way valve 102, and the third pipeline is provided with a liquid discharge valve 103. The liquid separating valve 101 is connected to one side of the liquid inlet valve 301, and the check valve 102 and the liquid discharge valve 103 are mounted to the other side of the liquid inlet valve 301.
The composition structure and the working operation principle of the conduction liquid separator device of the solar water heater are as follows:
fig. 6 is a schematic view showing the condensing state of the operating structure of the heat exchange type solar water heater in which the outdoor wall-mounted heat collector 200 using the conductive liquid dispenser device is completely filled with the conductive liquid. The structure shown in the figure comprises 9 main components, namely a liquid separating tank 100, a liquid separating valve 101, a one-way valve 102, a liquid discharging valve 103, an outdoor wall-mounted heat collector 200, a liquid inlet valve 301, a liquid outlet valve 302, an indoor heat exchanger 400, a water tank 500 and the like.
Fig. 7 is a schematic view of normal circulation of the conductive liquid in the conduit using the conductive liquid dispenser device. The circulation working condition of partial condensation liquid state and partial saturation heat liquid state is shown when the heat conduction liquid in the pipeline of the outdoor heat collector 200 is in normal working circulation under the full irradiation of sunlight in the heat exchange type solar water heater filled with the conduction liquid and using the conduction liquid dispenser device; in the figure, the liquid dividing valve 101, the check valve 102 and the liquid discharge valve 103 are in a closed state, and the liquid inlet valve 301 and the liquid outlet valve 302 are in an open state.
When the heat transfer fluid in the pipe of the outdoor heat collector 200 is heated to a high temperature state (the heat transfer fluid in the pipe is in a saturated hot liquid state) due to the fact that cold water in the water tank 500 is not exchanged, and the saturated pressure expansion of the heat transfer fluid increases, the check valve 102 is opened by the heat transfer fluid which is saturated in the pipe and expands in pressure, and a part of the heat transfer fluid is divided to enter the liquid dividing tank 100, so that the expansion pressure of the heat transfer fluid in the pipe is reduced, and the normal circulation process of the heat transfer fluid in the pipe under the safe working pressure is maintained.
Fig. 8 is a schematic view of a liquid separation state of the liquid separation tank under a pressure condition, and when the check valve 102 is opened by the conductive liquid saturated and expanded in pressure in the pipeline, and the branched conductive liquid with saturated and expanded pressure enters the liquid separation tank 100, the outdoor heat collector 200 is in a normal circulation heating state under a safe pressure.
The specific application method is as follows:
(1) when the sunlight is sufficiently irradiated, in the normal use state of the conduction liquid, the liquid dividing valve 101 and the one-way valve 102 in the conduction liquid pipeline of the solar water heater are set in a closed state, and the liquid discharge valve 103 is set in a safe pressure value; the liquid inlet valve 301 and the liquid outlet valve 302 are in an open state.
(2) When the sunlight irradiation is sufficient but hot water is not used, when the conduction liquid reaches a saturated pressure expansion state, the one-way valve 102 in the conduction liquid pipeline of the solar water heater is automatically opened due to the ultra-safe pressure, so that part of the conduction liquid is shunted to enter the liquid separation tank 100, and the phenomenon that the pipeline leaks or bursts due to the fact that the volume of the conduction liquid is saturated due to heat and the pressure is increased is avoided.
(3) When the solar water heater is sensed to have low heat exchange efficiency and low water temperature in hot water, the liquid separating valve 101 and the liquid discharging valve 103 are manually opened, so that the conducting liquid in the liquid separating tank 100 flows back to the pipeline of the outdoor heat collector 200; after standing for 2-3 hours, the liquid separating valve 101 and the liquid discharging valve 103 are placed in a closed state, and the working system of the heat exchange type solar water heater is recovered to be in a normal working condition state.
Example 2
The embodiment is an intelligent application mode of a liquid distributor device, and on the basis of the structure disclosed in the embodiment 1, after a liquid distributing valve 101 and a liquid discharging valve 103 are changed into electromagnetic valves, the liquid distributor device can be designed and manufactured into products in two forms:
(1) programmable control type: a programmable controller with simple temperature measurement and timing control is designed and manufactured, whether the solar water heater is used every day or not, the programmable controller can be set in a time period when the water heater is in a room temperature working condition, opening and closing time of a liquid separating valve 101 and a liquid discharging valve 103 is automatically controlled, and operation of a heat exchange type solar water heater working system for discharging liquid of a liquid separating device is automatically finished to restore to a normal working condition.
(2) Wireless remote intelligent control type: a wireless remote control receiving and transmitting system unit is designed and manufactured, such as a mobile phone App operating system and a computer remote operating system, to carry out on-site or remote intelligent operation control on a dispenser device, namely, through wireless intelligent control, not only can the working program of the dispenser device be set, but also the temperature of conductive liquid, the temperature of water heating, various working conditions of a solar water heater and the like can be detected.
The invention discloses a conducting liquid knockout device and an application method thereof, which can be used for liquid separation, shunt and decompression when the saturated pressure of conducting liquid of a solar water heater expands and increases, and can also be used for liquid separation, shunt and decompression of liquid in pipelines of other devices and other methods. When the liquid expands and increases due to the saturation pressure in the pipeline working condition, the liquid is divided, shunted and decompressed by controlling the one-way valve 102 or other valves, and the liquid is stored in the liquid dividing tank 100; when the pipeline is in an off-working condition, the liquid separating valve 101 and the liquid discharging valve 103 are set in an open state, so that the liquid in the liquid separating tank 100 flows back to the pipeline of the outdoor heat collector 200 or other devices; after standing for a certain period of time, the liquid separation valve 101 and the liquid discharge valve 103 are closed to restore the normal use state of the piping liquid.
The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention, and various modifications and changes may be made by those skilled in the art. Any modification, equivalent replacement, or improvement made within the spirit and principle of the present invention should be included in the protection scope of the present invention.
