Description

Technical Field

[0001] This invention relates to the field of refrigeration compressor technology, specifically to a highly stable binary refrigeration compressor unit. Background Technology

[0002] The refrigeration compressor is the core component of the refrigeration system. Its function is to compress low-temperature, low-pressure refrigerant gas into high-temperature, high-pressure gas, allowing the refrigerant to circulate and achieve refrigeration. Its development history is long, with early models primarily using piston-type structures, which suffered from drawbacks such as high vibration, high noise, and low efficiency. In the 20th century, new types of compressors, such as rotary, scroll, and screw compressors, emerged, significantly improving performance. In recent years, development has focused on environmental protection and energy conservation. The main types include piston compressors (which compress the refrigerant by changing the cylinder volume through the reciprocating motion of a piston, suitable for small and medium-sized refrigeration equipment), rotary compressors (composed of a rotor and stator, compressing the refrigerant by changing the gap, used in household air conditioners, etc.), scroll compressors (composed of a fixed and moving scroll plate, compressing the refrigerant by reducing the space during movement, used in household and commercial air conditioners, etc.), and screw compressors (composed of meshing screws, compressing the refrigerant during rotation, used in large refrigeration systems).

[0003] In the current technical field, the matching relationship between compressors, condensers, expansion valves, and evaporators in the industry mainly relies on empirical estimation, lacking precise scientific calculations and actual analysis. This experience-based matching method has a large degree of subjectivity and uncertainty, and cannot fully consider the complex interactions between various components and the diversity of actual operating conditions. This leads to the selection of compressor power, condenser, expansion valve, and evaporator that are mismatched with the compressor or exceed actual requirements, which in turn affects the operating efficiency of the entire refrigeration system. Excessive compressor power is often accompanied by greater vibration and noise. Mismatch between components may cause the refrigerant flow state in the system to be unstable, generating airflow noise. If the heat dissipation capacity of the condenser cannot match the heat generation of the system, heat will accumulate in the system, causing the equipment temperature to rise. This not only affects the performance and lifespan of the equipment, but may also pose safety hazards. Summary of the Invention

[0014] Compared with the prior art, the beneficial effects of the present invention are:

[0015] 1. The first compressor compresses the low-temperature, low-pressure RA refrigerant inside into a high-temperature, high-pressure liquid refrigerant. After being cooled by the condenser, the high-temperature, high-pressure liquid refrigerant enters the receiver and expands. The expanded refrigerant passes through the dryer filter at the corresponding location, where trace amounts of moisture and oxide layer impurities mixed in during pipeline passage are filtered out. The filtered RA refrigerant then enters the first outlet throttling valve through the first solenoid valve, where it is throttled to form a low-temperature, low-pressure gaseous medium. This gaseous medium enters the bottom heat pipe, where the fins, in conjunction with the heat pipe, absorb heat from the gaseous medium passing through it. It then returns to the first compressor through the first return throttling valve and a one-way valve. When the above cycle reaches the specified temperature, the second solenoid valve opens, throttling the gaseous medium inside the first compressor to form a low-temperature, low-pressure gaseous medium. The uncondensed liquid refrigerant R enters the plate heat exchanger. Inside the second compressor, the refrigerant RA absorbs heat from the refrigerant R and returns to the first compressor for recirculation. Simultaneously, the second compressor starts, compressing its own low-temperature, low-pressure refrigerant RA into high-temperature, high-pressure liquid refrigerant. This high-temperature, high-pressure liquid refrigerant passes through an oil separator and enters the condenser for heat dissipation. The refrigerant then passes through a dryer filter at its corresponding location, which filters out trace amounts of moisture and oxide layer impurities mixed in during pipeline passage. After passing through the second outlet throttle valve, the refrigerant RA becomes a low-temperature, low-pressure gaseous medium that enters the bottom heat pipe. The fins, in conjunction with the heat-conducting cylinder, absorb heat from the gaseous medium passing through the top heat pipe and return to the second compressor via the second return throttle valve until the set low-temperature temperature is reached.

[0016] 2. The electric telescopic rod extends and drives the mounting frame to rotate upward to a vertical position. The scissor-type electric folding frame folds forward to drive the truss to move to the left. The second motors on the front and rear sides cooperate with the pulley seats at the corresponding positions to drive the upper limit slider at the corresponding position to move the rotating seat at the corresponding position to move to the left synchronously, so that the fan is closer to the fins. The motor inside the fan drives the fan blades to rotate to enhance airflow and improve heat exchange efficiency.

[0017] 3. Under the transmission of the bevel gear set and gears, the first motor drives the first rotating rods on both sides to rotate synchronously inward or outward through the fixed shafts on both sides. The first rotating rods on both sides drive the U-shaped seat to move forward or backward with the cooperation of the second rotating rod and the fixed rod. The U-shaped seat drives the fins at the corresponding positions above to move forward or backward with the cooperation of the second connecting shaft. The U-shaped seat drives the gear rods on both sides to rotate synchronously inward or outward from their own inside, so as to drive the folding frame to fold forward or unfold backward with the connection position with the fixed seat as the endpoint. In turn, the folding frame drives the fins at other positions to move forward or backward with the cooperation of several first connecting shafts above itself. In turn, the fins move back and forth outside the heat-conducting tube with the cooperation of the heat-conducting cylinder, while changing the spacing. This optimizes the airflow distribution between the fins according to different working conditions and fluid characteristics, increases the actual area participating in heat dissipation, and reduces thermal interference between the fins.

[0018] In summary, this invention can achieve the matching relationship between the compressor, condenser, expansion valve and evaporator, and has an accurate basis for combining theoretical calculations and heat absorption and release coefficients in practical applications, so as to achieve the optimal configuration of the whole refrigeration system. Furthermore, it can adjust the working efficiency of the evaporator in real time according to actual needs, so as to achieve the purpose of energy saving and noise reduction.

[0033] The working principle is as follows:

[0034] Step 1: The first compressor 7 compresses the low-temperature, low-pressure R404A refrigerant inside it into a high-temperature, high-pressure liquid refrigerant. After being cooled by the condenser 3, the high-temperature, high-pressure liquid refrigerant enters the receiver 2 and expands. The expanded refrigerant passes through the dryer filter 10 at the corresponding position, where trace amounts of moisture and oxide layer impurities mixed in during pipeline passage are filtered out. The filtered R404A refrigerant then enters the first outlet throttling valve 12 through the first solenoid valve 11, and after being throttled inside the first outlet throttling valve 12, it forms a low-temperature, low-pressure gaseous medium. The gaseous medium enters the bottom heat pipe 252. Inside, fins 253, in conjunction with the heat-conducting cylinder 254, absorb heat from the gaseous medium passing through the bottom heat-conducting pipe 252. The gas then returns to the first compressor 7 via the first return gas throttling valve 13 and the one-way valve 14. When the cycle reaches the specified temperature, the second solenoid valve 16 opens, allowing the low-temperature, low-pressure gaseous medium, throttled inside the first compressor 7, to enter the plate heat exchanger 15. The partially condensed liquid R23 refrigerant inside the second compressor 8 enters the plate heat exchanger 15. The R404A refrigerant inside the plate heat exchanger 15 absorbs heat from the R23 refrigerant and returns to the first compressor 7. The cycle repeats, and simultaneously, the second compressor 8 starts, compressing its internal low-temperature, low-pressure R23A refrigerant into a high-temperature, high-pressure liquid refrigerant. This high-temperature, high-pressure liquid refrigerant passes through the oil separator 9 and enters the condenser 5 for heat dissipation. The refrigerant then passes through the dryer filter 10, which filters out trace amounts of moisture and oxide layer impurities mixed in during pipeline passage. After passing through the second outlet throttle valve 17, the R23A refrigerant forms a low-temperature, low-pressure gaseous medium that enters the bottom heat pipe 252. The fins 253, in conjunction with the heat-conducting cylinder 254, circulate the gaseous medium passing through the top heat pipe 252. After absorbing heat, the gas returns to the second compressor 8 via the second return gas throttle valve 18 until the set low temperature is reached. Then, the energy and refrigeration curves of the first compressor 7 and the second compressor 8 at different temperatures are tested. After determining the power of the first compressor 7 and the second compressor 8, the required heat dissipation area and volume of the condenser 5 are calculated according to the heat dissipation power calculation formula. The heat dissipation power of the condenser 5 is determined, and the corresponding models of the first solenoid valve 11, the first outlet throttle valve 12, the first return gas throttle valve 13, and the one-way valve 14 of the throttling expansion valve are selected to achieve the optimal configuration of the entire refrigeration system.

[0035] Step 2: The electric telescopic rod 459 extends to drive the mounting frame 457, causing the mounting frame 457 to rotate upwards to a vertical position inside the two rotating seats 456. The scissor-type electric folding frame 444 folds forward to drive the truss 441. The roller seats 442 on both sides move along the outside of the guide rail 42 and limit the truss 441, so that the truss 441 drives the electric telescopic rods 459 on both sides to move to the left. The second motors 4510 on both sides drive the pulley seats 454 at the corresponding positions to rotate, thereby causing the belt 455 to rotate circumferentially with the cooperation of the pulley seat 454 on the other side, so as to drive the upper limit slider 453 at the corresponding position to move to the left along the outside of the guide rail frame 452. The upper limit sliders 453 on both sides cooperate to drive the rotating seats 456 at the corresponding positions to drive the mounting frame 457 to move to the left in sync, so that the fan 458 is close to the fins 253. The motor inside the fan 458 drives the fan blades to rotate to enhance airflow and improve heat exchange efficiency.

[0036] Step 3: After calculating the optimal heat absorption area of ​​the evaporator mechanism 2, the first motor 366 drives one end of the bevel gear set 367 to rotate. Under the transmission of the bevel gear set 367, the corresponding fixed shaft 364 drives the gear 365 and the first rotating rod 368 to rotate. The other gear 365 is engaged to drive the corresponding fixed shaft 364 to drive the first rotating rod 368 to rotate in the opposite direction. The two fixed shafts 364 drive the two first rotating rods 368 to rotate synchronously inward or outward. The two first rotating rods 368 drive the corresponding second rotating rod 3610 to rotate inward or outward around the axis of the fixed rod 369. Then, with the cooperation of the fixed rod 369, the U-shaped seat 362 is driven to move forward or backward. The U-shaped seat 362 is connected to the second... With the cooperation of the connecting shaft 363, the fins 253 at the corresponding positions above are driven to move forward or backward. The U-shaped seat 362 drives the gear rods 361 on both sides to rotate synchronously from the inside to the outside or from the inside, so as to drive the folding frame 34 to fold forward or unfold backward with the connection position with the fixed seat 33 as the endpoint. In turn, with the cooperation of several first connecting shafts 35 above itself, the folding frame 34 drives the fins 253 at other positions to move forward or backward. In turn, with the cooperation of the heat-conducting cylinder 254, the fins 253 move back and forth outside the heat-conducting pipe 252 and change the spacing at the same time. This optimizes the airflow distribution between the fins according to different working conditions and fluid characteristics, increases the actual area participating in heat dissipation and reduces thermal interference between the fins, thereby achieving the optimal heat absorption area of ​​the evaporator mechanism 2.
