[0002] With the advancement of science and technology, cold storage is widely used in life, and national policies also strongly support the development and application of photovoltaic technology. A complete cold storage contains many devices, among which the oil-gas separator is mainly used to filter lubricating oil and refrigerant gas, but the existing oil-gas separator also has some defects, such as secondary mixing after separation, insufficient filtration of small oil droplets, etc., so some improvements are made in the structure to improve the filtration efficiency. The heat exchanger exchanges heat to make the refrigerant gas get a certain degree of superheat and the refrigerant liquid get a certain degree of subcooling. When the two fluids flow, a boundary layer will be formed, which will reduce the heat exchange efficiency. The convection heat exchange of the two-phase fluid is not sufficient. Problems such as insufficient heat exchange are solved through special heat exchange pipes. The compressor is the "heart" of the cold storage and is very important in refrigeration. However, due to the problem of sudden power failure, the pressure in the compressor is very high during compression, and sudden power failure will cause damage to the compressor. The power of photovoltaic power generation has always been the research direction of many people. Due to the instability of solar radiation intensity, the maximum power is difficult to maintain. The maximum power tracking methods include constant voltage method, increased momentum method, perturbation observation method, etc. These methods have obvious advantages but also obvious disadvantages.

The photosensor 10-2 is used to detect light intensity.

[0041] The vapor compression refrigeration system includes an evaporator 1, a heat exchanger 4, a liquid reservoir 22, a compressor 14 and an oil-gas separator 19. The refrigerant liquid in the evaporator 1 forms a refrigerant gas after evaporation and flows into the heat exchanger 4. The refrigerant gas exchanges heat with the refrigerant liquid sent out of the liquid reservoir 22 and the photovoltaic panel cooling water 10-1 through the gas disturbance device 4-9 in the heat exchanger 4. The heat exchanger 4 is connected to the compressor 14, the compressor 14 is connected to the oil-gas separator 19, the oil-gas separator 19 is connected to the condenser 17, and the oil-gas separator 19 is connected to the compressor 14 to circulate the lubricating oil.

[0042] The compressor temporary power-off protection system includes a refrigerant temporary storage device 11, an electronic valve V 2 6. Compressor power off control module 25, indicator light 26, transistor 27, protective resistor R 1 28. Protection resistor R 2 30 and capacitor 29, the input end of compressor 14 is connected to the output end of refrigerant temporary storage 11, and the electronic valve V 2 6 is installed between the output end of the compressor 14 and the input end of the refrigerant temporary storage 11, and the electronic valve V 2 6 is installed between the output end of the compressor 14 and the input end of the oil-gas separator 19;

[0043] The left end of the compressor power-off control module 25 is connected to the left end of the capacitor 29, and the right end of the compressor power-off control module 25 is connected to the protection resistor R 2 The right end of capacitor 29 is connected to the first electrode of transistor 27, and the second electrode of transistor 27 is connected to the right end of capacitor 29 and protection resistor R 2 The left end of the transistor 27 is connected to the left end of the indicator light 26, and the right end of the indicator light 26 is connected to the protective resistor R 1 28, the lower end, protection resistor R 1 The upper end of 28 is connected to the protection resistor R 2 30 on the right.

[0044] The oil-gas separator 19 comprises an oil molecule baffle 20, a gas disturbance device 19-1, an oil dripping hole 31, a semipermeable membrane baffle 19-3, an oil collecting baffle 19-4, an oil droplet collecting device 19-5, a gas mixture inlet 19-6 and a lubricating oil outlet 19-7. The lubricating oil and refrigerant gas mixture enters from the gas mixture inlet 19-6, passes through the gas disturbance device 19-1 and blows to the oil collecting baffle 19-4, filters the large molecular oil droplets, passes through the gas disturbance device 19-1 again, passes through the semipermeable membrane baffle 19-3 to filter the small molecular oil droplets, and the filtered oil droplets drip through the oil dripping hole 31 in turn and flow into the oil droplet collecting device 19-5, and the oil droplets are collected and then flow out from the lubricating oil outlet 19-7; the oil dripping hole 31 is connected to the oil collecting baffle 19-4, and the gas disturbance device 19-1 can make the gas reach a turbulent state when flowing, thereby improving the filtering effect of the large molecular oil droplets.

[0045] The liquid storage tank 22 is connected to the heat exchanger 4 through a pipeline, and the refrigerant liquid in the pipeline is pumped by a centrifugal pump P 2 23 is delivered to heat exchanger 4, electronic valve V 7 24 controls the flow rate of refrigerant liquid in the pipeline.

[0046] The heat exchanger 4 is connected to the electronic expansion valve 3, which is connected to the electronic expansion valve 3 through the centrifugal pump P 1 2 Send the refrigerant liquid to the evaporator 1.

[0047] The heat exchanger 4 includes a gas disturbance device 13, a heat exchange tube 12, a bypass tube 4-1, an atomizing water pipeline 4-2, a refrigerant gas inlet 4-3 and a refrigerant gas outlet 4-4. The refrigerant gas inlet 4-3 is connected to the bypass tube 4-1. The bypass tube 4-1 blows out the refrigerant gas through the gas bypass device 4-9, and then performs convection heat exchange with the atomizing water pipeline 4-2 and the heat exchanger heat exchange tube 12, and then flows out from the refrigerant gas outlet 4-4.

[0048] A photovoltaic-biomass energy combined energy supply cold storage photoelectric conversion enhancement and equipment protection system, the maximum power tracking module 10-4 is mainly composed of two parts: one part is an intelligent control module, and the other part is a physical adjustment module controlled by the intelligent module. The main operation process is that the photovoltaic panel 10 first converts photons into electrons and then forms current. The maximum power tracking module 10-4 adjusts the operation mode by monitoring the temperature. The constant voltage method mainly used is this method. This method is easily affected by temperature, so the water of the cooling water atomization cooling device 10-3 and the photosensitive sensor 10-2 are used to jointly control the temperature. When the temperature changes too much, it is switched to the fuzzy control method mode. After the temperature is adjusted, it is switched back to the constant method. After the atomized water is cooled and cooled, it enters the heat exchanger 4 to exchange heat and cool with the refrigerant gas for recycling. Another intelligent module obtains the maximum light radiation intensity through the photosensitive sensors 10-2 around the photovoltaic panel, transmits the DC power out, and then inverts it into AC power through the inverter, and then connects it to the biomass energy turbine for time-sharing and shunt power supply.

[0049] After the current is generated, the compressor 14 starts to work, compressing the refrigerant gas into high temperature and high pressure, and then transporting it to the oil-gas separator 19. In the oil-gas separator 19, the refrigerant and lubricating oil mixture hits the baffle and the gas leaves. After filtering the large molecular oil droplets, the gas still carries fine oil droplet molecules, which are filtered through the semi-permeable membrane baffle 19-3 and then enter the condenser 17 for condensation.

[0050] The condensed refrigerant gas becomes liquid and enters the liquid storage tank 22 through the centrifugal pump P 2 23 is transported to the heat exchanger for cooling, where it exchanges heat with the low-temperature and low-pressure refrigerant coming out of the evaporator, then enters the evaporator 1 after being throttled by the electronic expansion valve 3, exchanges heat with the air in the pipeline and becomes gas, and the cycle repeats.

[0051] The compressor power failure temporary protection system mainly relies on the continuous discharge of the capacitor 29 to replace the power supply, starts the super capacitor through the potential difference, and extracts the refrigerant gas in the compressor 14 into the refrigerant temporary storage 11 at the same time, and then continues to start the compressor 14 after the power supply returns to normal, and re-enters the gas in the refrigerant temporary storage 11 into the compressor 14 for compression.

[0052] The whole system working process: when the sunlight shines on the photovoltaic panel 10, the PN junction in the photovoltaic panel 10 excites electrons and electron-hole pairs. The hole pairs and electrons flow in opposite directions in the PN junction. When flowing, they have opposite charges, so direct current is formed. The direct current is converted into alternating current after passing through the inverter 16 and connected to the biomass energy turbine 15 for grid power supply. The circuit is first connected to the compressor temporary power-off protection circuit. After the supercapacitor 29 is fully charged, the compressor 14 starts to inhale the refrigerant gas from the evaporator 1 for compression. After being compressed into high-temperature and high-pressure gas, it enters the oil separator 20 to filter out the lubricating oil carried in the gas. The lubricating oil is sent to the compressor 14 for continued use. The refrigerant gas enters the condenser 17, enters the liquid storage 22 after condensation, and then is pumped by the centrifugal pump P 2 The compressor is sent to the heat exchanger 4 to obtain a certain degree of supercooling, so that it evaporates faster after passing through the electronic expansion valve 3 for adiabatic throttling. After evaporation, it continues to enter the compressor 14 for compression to form a cycle of the entire system. The compressor temporary power failure protection system includes an intelligent control module 25, two protection resistors R 1 , R 2 28, 30, working indicator light 26, transistor 27, super capacitor 29. After power is turned on, capacitor 29 slowly stores electricity, and starts to discharge after full storage. Compressor 14 enters normal working mode, indicator light 26 lights up. When power is suddenly cut off, the intelligent module immediately controls the electric valve V through the signal of the potential difference between the two sides. 6 , so that the compressed refrigerant and the uncompressed refrigerant gas in the compressor 14 enter the refrigerant temporary storage container 11 together, the indicator light 26 goes out at the same time, the capacitor 29 continues to discharge to let the compressor 14 slowly stop, and after the staff solves the problem and the power supply is restored to normal, it restarts normal operation, the indicator light 26 lights up, and the refrigerant stored in the refrigerant temporary storage container 11 re-enters the compressor 14 for compression, and the whole system works normally.

[0053] See also Figure 2The maximum power tracking system includes a photovoltaic panel 10, photovoltaic panel cooling water 10-1, a cooling water atomization cooling device 10-3, a photosensor 10-2, a maximum power tracking module 10-4, a maximum light radiation tracking module 10-5, and a dual-axis rotation device 10-6. In the process of converting direct current into direct current by the photovoltaic panel 10, the output power needs to be controlled. Without considering the temperature, the maximum power output is a parabola, and the highest point is the maximum output power. Adding a maximum power tracking module 10-4 keeps the voltage near the maximum power. This control method is called the constant voltage method, which is the main control method used in this system. This control method requires The temperature remains unchanged. When the temperature on the surface of the solar photovoltaic panel 10 of the system does not change much, the voltage near the maximum power point of the system does not change much. Therefore, the temperature is mainly controlled by the atomized water and the photosensitive sensor 10-2 to sense the irradiation intensity. If the temperature changes too much, the intelligent system control is used to achieve the maximum power output according to the input conditions such as the sunlight intensity, the characteristics of the photovoltaic panel and the ambient temperature. This method is called fuzzy control. The fuzzy control method can correct the voltage in time so that it always maintains the maximum power output. After returning to normal, the constant voltage method is continued. The controllers of the two control methods are concentrated in the maximum power tracking module 10-4. In addition to controlling the temperature, the atomized cooling water can also reduce the temperature of the photovoltaic panel, so that the efficiency of power generation is improved. The atomized water flows into the pipeline and is transported to the heat exchanger 4 to exchange heat and cool the gas coming out of the evaporator 1, and then transported back to the photovoltaic panel 10 for further cooling.

[0054] join Figure 3 , Figure 4 , Figure 5 , Figure 6 The structure of the oil separator mainly includes an oil drop baffle 20, an oil collecting baffle 19-4, an oil collector 19-5, a semi-permeable membrane baffle 19-3, a gas disturbance device 19-1, an oil drop leakage device 19-2, and an oil drip hole 31. After the mixed gas with oil droplets enters from the gas mixture inlet 19-6, it is disturbed by the disturbance device 19-1 and then hits the oil collecting baffle 20 above. There is a small protruding cone on the baffle, which can weaken the impact force and better collect oil. The oil droplets on the baffle slowly flow into the drip hole 31 at the front end under the action of surface tension and gravity. The three-dimensional structure of the drip hole is shown in FIG. Figure 6The drip hole 31 can adjust the size of the hole diameter by the knob 31-1. When the knob 31-1 rotates, it drives the ratchet 31-2 below the hole to rotate, and the ratchet 31-2 drives the ratchet paddle 31-3 to rotate to adjust the size. The ratchet paddle 31-3 is fixed on the bolt 31-4. The size of the dripping oil droplets is controlled according to the gas flow rate to avoid secondary mixing and reduce the separation effect. After the large oil droplet molecules are filtered through the four baffles, there are still small oil droplet molecules in the gas. Then, the small oil droplet molecules are filtered by increasing the gas disturbance and passing through the semi-permeable membrane baffle 19-3. The drip hole 31 is in a straight line, and the oil droplets drip from top to bottom into the annular oil collecting plate below, and then return to the compressor through the oil outlet 19-7 below. The overall structure diagram of the gas disturbance device is as follows: Figure 5 When the gas flows through, the paddle in the middle will swing up and down irregularly, causing the airflow to swing. The faster the gas flow rate, the stronger the swing, thereby achieving the purpose of gas disturbance.

[0055] See also Figure 7 , Figure 8 , Fig. 9 , Fig.10 , Fig.11 , Fig.12 The main structure of the heat exchanger 4 includes a heat exchange tube 12, an atomized water pipeline 4-2, a gas diverter 4-1, and a disturbance device 4-9. After the refrigerant gas enters the diverter from the inlet 4-3, it is evenly diverted into the diverter and a better heat exchange effect is obtained by increasing the gas disturbance. The pipeline is arranged at an angle of 45 degrees to obtain more heat exchange area. The cross section of the pipeline is shown in 8. The concave and convex of the pipeline can weaken the boundary layer of the fluid, and small disturbance components are added inside and outside the pipeline. The small components outside the pipeline can make the airflow collide with each other, increase the disturbance, and enhance the heat exchange effect. The airflow direction is as follows Fig. 9 As shown, these small parts also act as fins, which can also increase the effect of convective heat transfer. For details of the arrangement of small parts outside the pipeline, see Fig.11 For a diagram of the small components in the pipeline, see Fig.10 The function of the lower end of the small component is mainly the normal line of the refrigerant liquid flow direction (V F ) direction. L ) and the normal direction in the pipe flow direction (V F ) angle, flush the pipeline in an oblique direction. This is the main function of the upper end of the small component. A total of 12 are installed in the same section of the pipeline as a group. See Figure 11 for the layout details. Install a group at a certain distance in the pipeline to allow the refrigerant liquid to flow toward (V F) offset and oblique flushing, which not only achieves a good boundary layer weakening effect, but also reduces the kinetic energy loss of refrigerant liquid offset to a certain extent. The boundary layer is weakened in two different directions, and the pipe cross-section is not a regular circle, which also weakens the boundary layer to a certain extent, making the convective heat transfer efficiency higher.
