Description

Technical Field

[0001] The invention belongs to the technical field of resistance wire defrosting and relates to a solar thermal resistance wire defroster.

[0002] The invention also relates to a defrosting method for a solar thermal resistance wire defroster. Background Art

[0003] Air quality not only affects the thermal comfort, health and work efficiency of human body, but also directly affects the quality of various types of products during production and storage. The rapid development of HVAC industry reflects the important role of air quality in production and life. However, with the rapid development of HVAC industry, its energy consumption problem has also become prominent. At present, global building energy consumption accounts for more than 21% of the total global energy delivery, and HVAC energy consumption is particularly huge. According to statistics, HVAC energy consumption in many countries such as China, the United States, the United Kingdom, Singapore, etc. has exceeded 40% of building energy consumption. Therefore, developing efficient and energy-saving air conditioning technology and reducing the energy consumption of air conditioning systems have become major goals of global sustainable development.

[0004] As a mature, efficient and environmentally friendly cooling and heating air conditioning equipment, air source heat pump has been widely used in building energy-saving projects. However, the frosting phenomenon of the air source heat pump evaporator during heating operation in cold areas in winter will reduce the system heating capacity and affect the comfort experience. When the frosting is severe, it may even cause the system to shut down or cause irreversible damage to the heat pump system. For the defrosting process of air source heat pumps in actual engineering applications, the defrosting effects of hot gas bypass defrosting method, reverse cycle defrosting method and heat storage defrosting method are mainly studied. However, this type of defrosting method is not suitable for defrosting under all environmental conditions or defrosting under different frosting conditions. Moreover, these defrosting methods have a series of disadvantages. For example, during the defrosting process, it is necessary to control the frequent reversal of the four-way valve or to defrost by air bypass, which will cause the room temperature to drop and affect the service life of the four-way valve. At the same time, there are a series of problems such as slow defrosting speed and high energy consumption. Now the defrosting method will be powered on or use the heat or heat in the equipment, which is not only complex in structure and difficult to operate, but also affects the defrosting efficiency.

[0005] Solar energy is a clean, pollution-free renewable energy source. Its thermal utilization has many forms, among which the thermal utilization of solar energy mainly includes solar water heaters, solar heating and other shower or heating needs. The equipment composition and layout are relatively fixed, the structure is relatively complex, and the heat use form is relatively single. In current research, solar energy is rarely used for the heat demand of equipment. Summary of the invention

[0006] The purpose of the present invention is to provide a solar thermal resistance wire defroster, which solves the problems existing in the background technology, significantly reduces heat loss, improves comprehensive operating efficiency, makes full use of renewable energy, and improves energy utilization efficiency.

[0007] Another object of the present invention is to provide a defrosting method for a solar thermal resistance wire defroster.

[0008] The first technical solution adopted by the present invention is a solar thermal resistance wire defroster, which is arranged on one side of the heat exchanger of the air source heat pump, and includes a window structure, an environmental monitoring device, a power storage system and a defrosting system.

[0009] The window structure comprises a window frame arranged on the surface of the air source heat pump, wherein a solar shutter is embedded in the window frame, and the solar shutter is driven by a micro motor.

[0010] The environment monitoring device is arranged on one side of the top of the window frame, and comprises a photoelectric sensor, a single-chip controller and an elevation angle azimuth angle driving unit which are connected in sequence, and the output end of the elevation angle azimuth angle driving unit is connected to a micro motor.

[0011] The power storage system includes a battery, wires, a controller and an inverter. The solar blinds are connected to the controller via wires, the controller is connected to the inverter, the inverter is connected to the battery, and the battery is used to supply power.

[0012] The defrost system includes a resistance wire, a temperature sensor and a power regulation controller. The temperature sensor is located on one side of the heat exchanger plate in the air source heat pump. The temperature sensor is connected to the power regulation controller. The power regulation controller is connected to the battery. The battery is connected to the resistance wire through an inverter. The resistance wire is horizontally distributed between the heat exchanger plates.

[0013] The first technical solution of the present invention is also characterized in that:

[0014] A plurality of evenly distributed ball bearings are embedded on both sides of the window frame, and the solar blinds include a plurality of parallel solar cell blinds. Both ends of the solar cell blinds are embedded in the ball bearings through synchronous belt blind shafts. A synchronous belt main shaft parallel to the solar cell blinds is provided on the top of the window frame. Both ends of the synchronous belt main shaft are respectively sleeved with synchronous belts parallel to both sides of the window frame. The synchronous belt blind shaft extends into the synchronous belt, and the synchronous belt is respectively meshed with the synchronous belt main shaft and the synchronous belt blind shaft, and one end of the synchronous belt main shaft is connected to a micro motor.

[0015] The two sides of the solar cell louver are respectively a solar cell and a waterproof protective shell, and the solar cell is a curved surface.

[0016] The main rotating shaft of the synchronous belt is connected to the micro motor through a micro motor driving rod.

[0017] The second technical solution of the present invention is a defrosting method for a solar thermal resistance wire defroster, which is specifically implemented according to the following steps:

[0018] Step 1, supplying power to the power storage system through solar blinds;

[0019] Step 2: The power storage system supplies power to the resistor to complete the defrosting process.

[0020] The second technical solution of the present invention is also characterized in that:

[0021] The specific process of powering the power storage system through the solar blinds in step 1 is as follows:

[0022] The photoelectric sensor transmits information such as the altitude angle and azimuth angle of the sun to the single-chip microcomputer controller, and the single-chip microcomputer controller then drives the altitude angle and azimuth angle drive unit to drive the micro motor; the micro motor drives the horizontal synchronous belt main shaft, and the synchronous belt main shaft drives the longitudinally arranged synchronous belt to rotate through the gears meshing with the synchronous belt, and the synchronous belt also drives the rotation of multiple rows of synchronous belt louver shafts through the gears with the synchronous belt louver shafts to adjust the angle of the solar cell; the solar cell is adjusted to charge the battery through the controller and inverter.

[0023] The control method of the single-chip microcomputer controller is as follows: first, the photoelectric sensor receives the light from the sun at different azimuths and altitudes, and the corresponding actual light intensity G is converted into a photocurrent signal through the photoelectric sensor; secondly, the photocurrent passes through the common emitter amplifier circuit of the single-chip microcomputer system to amplify the corresponding current and voltage values, and generates digital voltage and current signals through the A / D converter, and the converted digital voltage and current signals are given to the single-chip microcomputer, and then decoded and compiled by the single-chip microcomputer, and then processed by the D / A module of the single-chip microcomputer to generate continuous analog voltage and current signals, and the corresponding continuous analog voltage signal U2=U out , U out is the output voltage, and its corresponding continuous simulated current signal The voltage and current signals output by the single-chip microcomputer are used as input signals of the altitude and azimuth driving unit, which drive the motor load to generate motor driving power, drive the micro motor, and finally adjust the opening and closing and rotation angle of the solar cell.

[0024] Wherein step 2 is specifically implemented as follows:

[0025] The defrost system is turned on, and the temperature sensor, power regulation controller, battery, inverter, and resistance wire are turned on; the temperature sensor detects the temperature Ts between the heat exchanger plates and starts to calculate the defrost time t; the temperature sensor transmits the temperature information between the heat exchanger plates to the power regulation controller; the circuit is turned on, and the power regulation controller adjusts the power supply of the battery; the temperature sensor presets the defrost temperature to T1~T2, specifically:

[0026] When the defrosting time is t=nt0, (n=1,2,3,4.......), the temperature sensor detects the temperature between the heat exchanger plates as T s ;

[0027] When T s When ≤T1, the battery provides 2Q electricity to the resistance wire;

[0028] When T1<T s When ≤T2, the battery provides Q electricity to the resistor;

[0029] When T2<T s The battery does not provide power to the resistor.

[0030] Where t0, T1, T2, and Q are all variable parameters of the system.

[0031] The electricity flows out of the battery, passes through the inverter, and is finally provided to the resistor. The resistor obtains the corresponding amount of electricity and generates heat for defrosting.

[0032] The beneficial effects of the present invention are:

[0033] The solar thermal resistance wire defroster of the present invention is an air source heat pump unit with solar cell louvered panels for power generation and resistance wire defrosting. When the resistance wire defrosting is running, the compressor and the fan are not started during the defrosting process, and almost no energy is consumed. The heat is almost completely generated by the solar cell panel, which makes full use of renewable energy and improves energy utilization efficiency.

[0034] There is no high or low pressure switching during the defrosting process, which eliminates the impact and fluid reversal of the traditional defrosting method, effectively protects the operating safety of each component, extends its service life, and eliminates defrosting noise.

[0035] The defrost system is a feedback control system that can automatically adjust the temperature inside the heat exchanger.

[0036] The solar panels can generate electricity by adjusting their opening and closing angles according to the sun's altitude. They can also protect the solar panels at night and extend their lifespan.

[0037] The present invention combines the meshing rotation system to effectively combine the environmental monitoring device and the solar cell louver regulating device, so that the entire system is convenient and flexible to adjust, and uses mechanical ingenuity, which is energy-saving and environmentally friendly.

[0048] The present invention provides a solar heat resistance wire defroster, such as Figure 1 and Figure 8 As shown, it includes a window structure, an environmental monitoring device, a solar cell louver control device, a power storage system and a defrosting system.

[0049] like Figure 2 , Figure 4and Figure 5 As shown, the window structure includes a window frame 1, a micro motor 2, a meshing system, a solar cell louver 6 and a ball bearing 7; the solar cell louver 6 has a synchronous belt louver shaft 5 at both ends, and both ends of the synchronous belt louver shaft 5 are placed in the ball bearings 7 located in the window frame 1; the meshing rotation system is composed of a synchronous belt main shaft 3, a synchronous belt 4 and a synchronous belt louver shaft 5, the synchronous belt main shaft 3 and the synchronous belt 4 are matched in size and rotationally matched, the synchronous belt 4 and the synchronous belt louver shaft 5 are matched in size and rotationally matched and are located in the window frame 1; the window frame 1 is located on the outer surface of the air source heat pump, just in front of the heat exchanger.

[0050] The environmental monitoring device includes a photoelectric sensor 14, a single-chip microcomputer controller 15, an altitude angle and azimuth angle drive unit 22 and is located at the upper left end of the window frame 1; the micro motor 2 is pressed at the upper left corner of the window frame 1 and the left end is connected to the environmental detection device and the right end is connected to the main shaft of the synchronous belt 3; the upper end of the synchronous belt 4 is connected to the main shaft of the synchronous belt 3 and the lower end is connected in sequence to multiple rows of synchronous belt shutter shafts 5.

[0051] like Figure 1 As shown, the power storage system includes a battery 8, a wire 9, a controller 10 and an inverter 11. The controller 10 (the number of which is the same as the synchronous belt shutter shaft 5) is located in the window frame 1 and is on the same horizontal line with each row of synchronous belt shutter shafts 5, as shown in FIG. Figure 1 As shown, the battery 8 and the inverter 11 are located between the window and the partition 20 in the evaporator, and the electricity flows from the solar cell 12 through the wire 9 first into the inverter 11 and then into the battery 8; the defrost system is composed of a resistance wire 16, a temperature sensor 17, a battery 8 and a power regulation controller 23, the temperature sensor 17 is located between the heat exchanger plates 19, and the power regulation controller 23 is located between the temperature sensor 17 and the battery 8.

[0052] Example

[0053] like Figure 7 As shown, the photoelectric sensor 14 of the environmental monitoring device transmits information such as the altitude angle and azimuth angle of the sun to the single-chip controller 15, which then drives the altitude angle and azimuth angle drive unit 22, and finally drives the micro motor 2; and the meshing rotation system in the window structure is driven by the micro motor 2, and the specific steps are: the micro motor 2 drives the horizontal synchronous belt main shaft 3, and the synchronous belt main shaft 3 drives the longitudinally arranged synchronous belt 4 to rotate through the gear meshing with the synchronous belt 4, and the synchronous belt 4 also drives the multiple rows of synchronous belt louver shafts 5 to rotate through the gears with the synchronous belt louver shaft 5, thereby completing the entire meshing rotation system.

[0054] like Figure 6As shown, on a sunny day, the solar cell louver 6 starts to rotate from 0° on one side of the solar cell 12 according to the angle of sunlight. At night, one side of the waterproof protective shell 13 of the solar cell louver 6 faces outward, and the micro motor 2 stops driving, completing a cycle of work, and then repeats the above working steps when it is a sunny day; if on a sunny day, according to the needs of the entire air-cooled heat pump system, the micro motor 2 adjusts the solar cell louver to a certain appropriate position, the micro motor 2 stops driving, and the solar cell louver 6 maintains the angle unchanged under the support of the meshing system; during the entire working process, the micro motor 2 drives the meshing system through the control system, and the meshing system drives the solar cell louver 6 to rotate; specifically, the rotation of the synchronous belt louver shaft 5 in the window body is supported and rotated in conjunction with the ball bearing 7 located on the side of the window frame 1.

[0055] In addition, the power storage system generates electricity through the solar cells 12 of the solar cell louver 6 during sunny days, flows through the controller 10 via the wires 9, flows into the inverter 11, and is finally stored in the battery 8.

[0056] In this solution, the working principle of the photoelectric sensor and the single chip controller 15 is as follows:

[0057] The photoelectric sensor is designed based on the characteristics of the photosensitive element. The following steps are included based on the characteristics of the photoelectric sensor:

[0058] Step 1: First, sunlight will continuously illuminate the photosensitive element of the photoelectric sensor from different azimuths and altitudes. The photosensitive element will receive the corresponding actual light intensity, which will generate three types of currents, namely, photocurrent I L , forward current I F , and the external circuit current. Under the condition of forward voltage V, the forward current equation can be obtained as: Among them, V represents the photo-generated voltage, I S It represents the reverse saturation current;

[0059] Step 2: Secondly, under the condition of constant light intensity, as the light irradiates the photocell more deeply, the concentration of photogenerated carriers generated in the photoelectric sensor will decrease instead; the photogenerated current I L The formula is as follows: Where A refers to the light receiving area of ​​the photocell, q refers to the charge, and L P and L N Refers to the depth of diffusion of carriers in the p-region and the n-region of the photoelectric sensor. The current flowing through the load: I = I L -I F ,Right now:

[0060] Step 3: Based on the above situation, we can construct the current model of the photoelectric sensor: Where: I SC is the short-circuit current, I sc,s It is the short-circuit current under standard test (25℃, 1000w / m 2 ), K l is the temperature coefficient, Δ r is the temperature difference between the actual conditions and the standard conditions, G n is the standard light intensity, G is the actual light intensity, where G = Aφcosβ, where A is the light receiving area of ​​the photoelectric sensor, φ is the luminous flux, and β is the irradiation angle of the light relative to the normal on the surface of the photoelectric sensor.

[0061] The controller is a single-chip microcomputer controller 15. The current signal input to the single-chip microcomputer is the photocurrent signal transmitted from the photoelectric sensor. The photocurrent signal has a low current value and is amplified by the single-chip microcomputer common emitter amplifier circuit module. And satisfy U in =I in R in , I in =I sc , R in >>R f , R f is the feedback resistor, R in is the input resistance; U in is the input voltage, U out The A / D module of the microcontroller generates digital voltage and current signals, and then converts the digital voltage and current signals to the microcontroller, and then decodes and compiles them, and then processes them through the D / A module of the microcontroller to generate continuous analog voltage and current signals. The corresponding continuous analog voltage signal is U2=U out , the corresponding continuous simulated current signal

[0062] Its driving unit is a driving motor module. The driving motor input voltage corresponds to the continuous simulated voltage signal U2 and the input current corresponds to the continuous simulated current signal I2, and the corresponding motor driving power is obtained. ( is the power factor).

[0063] The control process of this scheme is as follows: first, the photoelectric sensor receives the light from the sun at different azimuths and altitudes, and the corresponding actual light intensity G (A is the light receiving area of ​​the photocell, φ is the luminous flux, and β is the irradiation angle of the light relative to the normal on the surface of the photocell). The photoelectric sensor converts the actual light intensity G into a photocurrent signal; secondly, the photocurrent passes through the common emitter amplifier circuit of the single-chip microcomputer system to amplify the corresponding current and voltage values, and generates digital voltage and current signals through the A / D converter, and the converted digital voltage and current signals are given to the single-chip microcomputer, and then decoded and compiled by the single-chip microcomputer, and then processed by the D / A module of the single-chip microcomputer to generate continuous analog voltage and current signals, and the corresponding continuous analog voltage signal is U2=U out , the corresponding continuous simulated current signal The voltage and current signals output by the microcontroller are used as input signals for driving the motor, which generates motor driving power through the driving motor load, drives the meshing rotation system, and finally adjusts the opening and closing and rotation angle of the solar panel.

[0064] The two-way flow between the battery 8 and the inverter 11 means that the electricity required by the micro motor 2 in the window structure can flow from the battery 8 into the inverter 11 and then be transferred to the micro motor 2; the electricity required by the resistor 16 can flow from the battery 8 into the inverter 11 and then be transferred to the resistor 16.

[0065] When the battery 8 does not store enough electricity, the control system transmits this information to the power grid, and the power grid will supply the insufficient electricity. When the battery 8 has surplus electricity after meeting the power consumption of the micro motor 2 and the resistor 16, it can be fed into the main supply circuit for use by other devices.

[0066] The power of the battery 8 is only turned on when the surface of the heat exchanger plate 19 in the evaporator is frosted in winter, and then flows into the inverter 11 and finally transferred to the resistor 16. At other times, the resistor 16 is not energized.

[0067] A further defrosting system is composed of a resistance wire 16 and a temperature sensor 17. The temperature sensor 17 is located between the heat exchangers 19. In winter, frost will form on the surface of the heat exchanger 19 in the evaporator. At this time, electricity flows from the battery 8 into the inverter 11 and is then transferred to the resistance wire 16. The resistance wire 16 starts to generate heat and finally melts the frost on the surface of the heat exchanger plate 19.

[0068] Specifically, the setting range of the temperature sensor 17 between the heat exchanger 19 is repeatedly tested through experiments, and a suitable defrost temperature between T1 and T2 is set in advance. The temperature sensor 17 senses the temperature. When the temperature exceeds the variation range, the temperature sensor 17 feeds back the temperature change information to the power regulation controller 23. The power regulation controller 23 regulates the battery 8 to increase or decrease the power supplied to the resistor 16, so that the resistor 16 generates corresponding heat for defrosting, so that the defrost temperature is within a normal range.

[0069] The specific steps are as follows:

[0070] The defrosting system is turned on, the temperature sensor 17, the power regulating controller 23, the battery 8, the inverter 11, and the resistance wire 16 are turned on; the temperature sensor 17 detects the temperature Ts between the heat exchanger plates 19 and starts to calculate the defrosting time t; the temperature sensor 17 transmits the temperature information between the heat exchanger plates 19 to the power regulating controller 23; the circuit is turned on, and the power regulating controller 23 adjusts the power supply of the battery 8 specifically as follows:

[0071] When the defrosting time is t=nt0, (n=1, 2, 3, 4.......), the temperature sensor 17 detects the temperature between the heat exchanger plates 19 as T s ;

[0072] When T s When ≤T1, the battery 8 provides 2Q of electricity to the resistor 16;

[0073] When T1<T s When ≤T2, the battery 8 provides Q electricity to the resistor 16;

[0074] When T2<T s When the battery 8 does not provide electricity for the resistance wire 16.

[0075] Where t0, T1, T2, and Q are all variable parameters of the system.

[0076] After defrosting is finished, the circuit is disconnected, the power regulation controller 23 no longer regulates the storage battery 8, and the resistance wire 16 stops working.
