Description

Technical Field

[0001] This invention relates to the field of kitchen fixed-point cooling air conditioning technology, specifically to a kitchen air conditioning system that adapts to high-temperature environments. Background Technology

[0002] Currently, commercial kitchen air conditioners are mainly divided into seven categories, classified by installation / air supply / self-cooling methods, each with clear advantages and disadvantages and applicable scenarios. Among them: 1. Workstation type (for chefs only): It is only effective in a localized area, cannot cover the entire kitchen, has a small air volume, and the filter is still easily clogged by oil fumes, requiring frequent cleaning; 2. Ceiling-mounted (ceiling-mounted / embedded) type is complicated to install (requires ceiling), maintenance requires climbing, cooling capacity decreases faster than cabinet type, and it still needs to be cleaned frequently when there is a lot of oil smoke. Third, cabinet-style (floor-standing / freestanding) units take up floor space, are noisy, are expensive, and are inconvenient to move. Fourth, split-type (kitchen-specific, not household) indoor units are still prone to oil accumulation, have a rapid decrease in cooling capacity (40%–50% reduction in 3 months), require frequent disassembly and cleaning, and are not suitable for heavy oil fumes.

[0003] V. Integrated type (dedicated all-in-one machine for preventing oil fumes) Key features: Fully enclosed oil-proof design, nano-ceramic evaporator + high-efficiency filter + self-cleaning. Advantages: Strongest oil resistance (adhesion reduced by 70%+), stable cooling (still 90%+ after 6 months), long maintenance cycle (3+ months), high temperature resistance (60℃), intelligent self-cleaning. Disadvantages: High price, complex installation, lower airflow than cabinet type, large initial investment. Suitable for: Chinese restaurants with heavy oil fumes, roast duck / barbecue, chain restaurants, and those with a long-term business focus. VI. Water-cooled / heat recovery type (high-end / energy-saving) Core features: Water cooling + waste heat recovery for hot water production, fresh air supply at designated locations. Advantages: High heat dissipation efficiency (18% higher than air cooling), stable, high temperature resistance, dual output of cooling and hot water, energy saving of 15%–30%, fresh air purification, suitable for large kitchens. Disadvantages: Highest cost, requires cooling water / pipe connection, complex installation, high maintenance costs, unsuitable for small kitchens. Suitable for: star-rated hotels, central kitchens, chain groups, energy-saving priority projects 7. Outdoor air-cooled integrated unit (commercial integrated unit with oil fume prevention).

[0004] Advantages: Precise cooling is delivered to the work area via air ducts (from 43℃ to 28℃ in the stove area); the evaporative heat exchanger always provides a fresh air environment with no oil fume clogging the filter; the air ducts have no maintenance costs; and the main unit does not drip water.

[0005] Disadvantages: First, it requires the installation of insulated air supply ducts, resulting in high installation costs. Second, it is not suitable for household or small kitchens. Third, when the outdoor summer temperature exceeds 45℃ or even 50℃, the air conditioner compressor will overheat and trigger protection because the evaporator is always supplying fresh air.

[0006] Suitable for: Cooling projects in hotels and large kitchens.

[0007] Currently, the fatal overheating protection issues that are prone to occur in the above seven models can only limit the operating temperature to ≤43℃, which restricts the application scenarios and thus hinders the development of commercial kitchen air conditioners.

[0008] To address the issue of overheating protection issues in existing outdoor air-cooled integrated (oil fume-proof commercial integrated units) when outdoor temperatures exceed 45°C in summer, this invention provides a kitchen air conditioning system that adapts to high-temperature environments. Summary of the Invention

[0009] This invention provides a kitchen air conditioning system that adapts to high-temperature environments, solving the problems of existing kitchen air conditioning systems being severely limited by temperature, prone to overheating protection, and having limited usage conditions.

[0010] The present invention is implemented as follows: an adaptive high-temperature environment kitchen air conditioning system, comprising a compressor, a finned condenser, a filter, a first Y-type tee, a first electronic expansion valve, a finned evaporator, a system stabilizer, a second Y-type tee, and a refrigerant storage tank connected in sequence by connecting pipes, and forming a refrigerant circulation loop; The output end of the aforementioned second Y-type tee is equipped with a return gas temperature sensor, and the aforementioned return gas temperature sensor is connected to an AI intelligent control module.

The aforementioned exhaust sensor is installed on the compressor exhaust pipe of the compressor, and the aforementioned return gas temperature sensor is installed on the compressor return gas pipe of the compressor. The evaporator outlet of the aforementioned finned evaporator is connected to the condenser-side inlet of the aforementioned system stabilizing balancer via pipe line three. The exhaust port of the compressor is connected to the condenser inlet of the finned condenser via the compressor exhaust pipe. The condenser outlet of the aforementioned finned condenser is connected to the inlet of the aforementioned filter via a pipeline; The outlet of the aforementioned filter is connected to the first port of the aforementioned first Y-type tee via a pipeline; The second port of the first Y-type tee is connected to the inlet of the first electronic expansion valve via pipe one, and the outlet of the first electronic expansion valve is connected to the evaporator inlet of the finned evaporator via pipe two. The condenser-side outlet of the aforementioned system stabilizer is connected to the first port of the aforementioned second Y-type tee via pipe three. The second port of the aforementioned second Y-type tee is connected to the refrigerant storage tank via the compressor return line, and the aforementioned refrigerant storage tank is connected to the aforementioned compressor; The central processing unit of the AI ​​intelligent control module is electrically connected to the first electronic expansion valve and adjusts the opening of the first electronic expansion valve according to the temperature signal detected by the return gas temperature sensor.

[0011] As one embodiment of the present invention, an auxiliary cooling circuit is also included, wherein the auxiliary cooling circuit includes a second electronic expansion valve; The inlet of the aforementioned second electronic expansion valve is connected to the third port of the aforementioned first Y-type tee via pipe four; The outlet of the aforementioned second electronic expansion valve is connected to the evaporator-side inlet of the aforementioned system stabilizer via pipe five; The evaporator-side outlet of the aforementioned system stabilizer is connected to the third port of the aforementioned second Y-type tee via pipe six.

[0012] As one embodiment of the present invention, the central processing unit of the AI ​​intelligent control module is electrically connected to the second electronic expansion valve and controls the opening degree of the first electronic expansion valve and the second electronic expansion valve according to the temperature signal transmitted by the return gas temperature sensor.

[0013] As one embodiment of the present invention, the set threshold of the above-mentioned return gas temperature sensor is 25°C. When the return gas temperature is detected to be higher than 25°C, the central processing unit of the above-mentioned AI intelligent control module starts to adjust the opening of the above-mentioned first electronic expansion valve.

[0014] As one embodiment of the present invention, an evaporator fan is provided on one side of the finned evaporator. The evaporator fan is provided with an evaporator fan inlet and an evaporator fan outlet. An air inlet sensor is provided at the air inlet of the evaporator fan. The air inlet sensor is electrically connected to the central processing unit of the AI ​​intelligent control module.

[0015] As an embodiment of the present invention, when the outdoor ambient temperature is higher than 45°C and the air inlet temperature of the finned evaporator is higher than 45°C, the central processing unit of the AI ​​intelligent control module adjusts the first electronic expansion valve and the second electronic expansion valve to control the exhaust temperature of the compressor below 115°C to prevent the compressor from triggering overheat protection.

[0016] In one embodiment of the present invention, the finned evaporator is positioned above the finned condenser, and the condensate inlet of the finned evaporator is connected to the circulating water inlet of the finned condenser.

[0017] As one embodiment of the present invention, the above-mentioned system stabilizer is a heat exchanger. The above-mentioned system stabilizer is provided with independent condenser side flow channel and evaporator side flow channel. The above-mentioned system stabilizer exchanges heat between the main circuit refrigerant flowing out from the condenser side outlet and the auxiliary flow channel refrigerant flowing out from the evaporator side outlet, thereby reducing the temperature of the mixed gas returning to the compressor.

[0018] In one embodiment of the present invention, the refrigerant in the refrigerant storage tank is R410a or R32.

[0019] As one embodiment of the present invention, a condenser fan for accelerating airflow is also provided on one side of the finned condenser described above.

[0020] The beneficial effects of this invention are: 1. This invention solves the problem of traditional kitchen air conditioners easily overheating and shutting down under extreme high-temperature conditions by introducing an auxiliary cooling circuit and a system stabilizer. When the return gas temperature sensor detects an abnormal return gas temperature or the inlet air temperature exceeds the 45°C threshold, the AI ​​intelligent control module immediately activates the second electronic expansion valve and uses the system stabilizer to perform secondary cooling of the refrigerant in the main circuit. This allows the system to accurately control the compressor exhaust temperature below the safe threshold of 115°C, effectively preventing the compressor from shutting down due to excessively high exhaust temperature. This ensures the continuous and stable operation of the kitchen air conditioner during hot seasons or high-intensity cooking environments, improving the comfort of chefs working in the kitchen. 2. This invention utilizes an AI-based intelligent control system. Through multi-dimensional data acquisition from exhaust gas sensors, return gas temperature sensors, and intake air sensors, the central processing unit dynamically adjusts the opening combination of the first and second electronic expansion valves based on real-time heat load. This adaptive adjustment mechanism not only intervenes promptly when the return gas temperature exceeds 25°C to prevent system overheating but also maintains the evaporator's optimal heat exchange efficiency, avoiding ineffective energy loss. Compared to traditional systems, this invention's intelligent control system significantly reduces energy consumption and improves the system's energy efficiency ratio while ensuring cooling performance. 3. In terms of structure, the present invention places the finned evaporator above the finned condenser and guides the condensate produced by the evaporator to the condenser for spray cooling. This not only utilizes the latent heat of vaporization of the condensate to enhance the heat dissipation of the condenser, but also solves the problem of inconvenient condensate discharge and realizes the recycling of water resources. 4. The integrated system stabilizer in this invention not only performs the functions of gas-liquid separation and pressure buffering, but also achieves efficient heat exchange between the main and auxiliary circuits through an internal independent flow channel, reducing the need for additional external cooling devices.

Detailed Implementation

[0023] To make the objectives, technical solutions, and advantages of this invention clearer, the invention will be further described in detail with reference to specific embodiments. It should be understood that the specific embodiments described herein are merely illustrative and not intended to limit the invention.

[0024] The present invention provides a kitchen air conditioning system that is adaptive to high temperature environment, comprising a compressor 1, a finned condenser 7, a filter 9, a first Y-type tee 11, a first electronic expansion valve 41, a finned evaporator 31, a system stabilizer 19, a second Y-type tee 24 and a refrigerant storage tank 18 connected in sequence by connecting pipes, and forming a refrigerant circulation loop.

[0025] Specific embodiment: The present invention provides a kitchen air conditioning system that adapts to high temperature environment. The system of the present invention includes a basic refrigerant circulation loop, as well as an auxiliary cooling loop and an AI intelligent control module specially designed by the present invention.

[0026] like Figures 1-2 As shown, the refrigerant circulation loop includes a compressor 1, a finned condenser 7, a filter 9, a first Y-type tee 11, a first electronic expansion valve 41, a finned evaporator 31, a system stabilizer 19, a second Y-type tee 24, and a refrigerant storage tank 20, which are connected in sequence through connecting pipes.

[0027] The connection relationships of the components in the refrigerant circulation loop are as follows: The exhaust port 2 of compressor 1 is connected to the condenser inlet 5 of finned condenser 7 through compressor exhaust pipe 3; The condenser outlet 8 of the finned condenser 7 is connected to the inlet of the filter 9 via a pipeline; The outlet of filter 9 is connected to the first port of the first Y-type tee 11 via a pipeline; The second port of the first Y-type tee 11 is connected to the inlet of the first electronic expansion valve 41 through pipe 12, and the outlet of the first electronic expansion valve 41 is connected to the evaporator inlet 32 ​​of the finned evaporator 31 through pipe 2 40. The evaporator outlet 30 of the finned evaporator 31 is connected to the condenser side inlet 29 of the system stabilizer 19 via pipe 3 16. like Figure 2 As shown, the condenser-side outlet 26 of the system stabilizer 19 is connected to the first port of the second Y-type tee 24 via pipe 25; the second port of the second Y-type tee 24 is connected to the refrigerant storage tank 20 via the compressor return pipe 21, and the refrigerant storage tank 20 is then connected back to the compressor 1's return port via pipe, thus forming a closed main refrigeration cycle. In this embodiment, the refrigerant in the refrigerant storage tank 20 is R410a.

[0028] To enhance the system's ability to adapt to the high-temperature environment of the kitchen, an auxiliary cooling circuit is added to the system. This circuit includes a second electronic expansion valve 14, whose inlet is connected to the third port of the first Y-type tee 11 via pipe four 13; the outlet of the second electronic expansion valve 14 is connected to the evaporator-side inlet 17 of the system stabilizer 19 via pipe five 15; the evaporator-side outlet 22 of the system stabilizer 19 is connected to the third port of the second Y-type tee 24 via pipe six 23, and after merging with the compressor return gas pipe 21 at the second Y-type tee 24, it flows back to the refrigerant storage tank 20 and the compressor 1.

[0029] In addition to its cooling function, the system stabilizer 19 also serves as a gas-liquid separator and buffer, ensuring that the refrigerant returning to the compressor 1 is in a pure gaseous state, thus protecting the compressor from liquid slugging damage.

[0030] To further improve energy efficiency, in this embodiment, the finned evaporator 31 is positioned above the finned condenser 7. The condensate produced by the finned evaporator 31 is collected through the condensate inlet 34 and directed to the circulation inlet 42 of the finned condenser 7. The evaporation of the condensate carries away a significant amount of latent heat, assisting the finned condenser 7 in dissipating heat and reducing condensation pressure.

[0031] The innovation of this invention lies in its ability to adaptively adjust to high-temperature environments through an AI intelligent control module. The AI ​​intelligent control module includes a central processing unit and multiple sensors electrically connected to it.

[0032] The sensors include exhaust sensor 4, return air temperature sensor 33, and intake air sensor 38.

[0033] Among them, the exhaust sensor 4 is installed on the compressor exhaust pipe 3 of the compressor 1 to monitor the compressor exhaust temperature in real time; the return gas temperature sensor 33 is installed on the compressor return gas pipe 21 of the compressor 1 and is located at the output end of the second Y-type tee 24 to monitor the return gas temperature of the compressor 1 in real time. An air inlet sensor 38 is installed at the air inlet 39 of the evaporator fan 36 on one side of the finned evaporator 31 to monitor the real-time ambient temperature of the kitchen.

[0034] Meanwhile, the central processing unit of the AI ​​intelligent control module is electrically connected to the first electronic expansion valve 41 and the second electronic expansion valve 14 respectively. By adjusting the opening of the first electronic expansion valve 41 and the second electronic expansion valve 14, the refrigerant flow and pressure are regulated to avoid excessive refrigerant causing the condensing temperature to be too high, which would lead to the compressor overheating protection problem and enable the compressor to run continuously.

[0035] Working methods and principles: Mode 1: Standard cooling mode operation. When the kitchen ambient temperature is within the normal range, i.e., below 45℃, the system operates in the following cycle: Compression: Compressor 1 starts and compresses the low-temperature, low-pressure gaseous refrigerant R410a into high-temperature, high-pressure vapor, which is then transported to the condenser inlet 5 through the exhaust port 2 and the compressor exhaust pipe 3. Condensation: High-temperature and high-pressure steam enters the finned condenser 7 through the condenser inlet 5, and is rapidly cooled down by the action of the condenser fan 6, condensing into a medium-temperature and high-pressure liquid refrigerant; Throttling: Liquid refrigerant flows out from condenser outlet 8, is filtered by filter 9, and then enters the first Y-type tee 11, subsequently flowing through the first electronic expansion valve 41. At this time, the central processing unit of the AI ​​intelligent control module controls the first electronic expansion valve 41 to its normal opening degree, so that the refrigerant is throttled and depressurized by the first electronic expansion valve 41 into a low-temperature, low-pressure gas-liquid mixture; Evaporation: The low-temperature, low-pressure gas-liquid mixture enters the finned evaporator 31 through the evaporator inlet 32, and absorbs heat from the kitchen air under the action of the evaporator fan 36 and evaporates into gaseous refrigerant; Return gas balance: After evaporation, the gaseous refrigerant enters the condenser side of the system stabilizer 19 through the evaporator outlet 30, and then returns to the refrigerant storage tank 20 and compressor 1 through the second Y-type three-way valve 24 to complete the cycle.

[0036] When the system is in an extreme high-temperature environment, such as when the outdoor temperature exceeds 45°C in summer and the heat load inside the kitchen is high, the AI ​​intelligent control module activates a multi-level protection mechanism: Mode 2: Overheat warning adjustment: The return gas temperature sensor 33 monitors the refrigerant return gas temperature in the compressor return gas line 21 in real time. When the detected refrigerant return gas temperature is higher than the preset threshold of 25°C, the central processing unit determines that the compressor in the system is at risk of overheating. At this time, the central processing unit issues an instruction to finely adjust and reduce the opening of the first electronic expansion valve 41, thereby reducing the refrigerant flow rate and decreasing the amount of refrigerant evaporation in the evaporator, resulting in a lower evaporation temperature. The evaporator discharge temperature is directly related to the evaporation temperature, so the discharge temperature will also decrease accordingly, thereby reducing the refrigerant return gas temperature and preventing the compressor suction temperature from becoming too high.

[0037] Mode 3: Extreme High Temperature Regulation When the intake air sensor 38 detects that the intake air temperature of the finned evaporator 31 is higher than 45°C, and the exhaust air sensor 4 confirms that the system is under high load, the system enters extreme operating mode: Auxiliary circuit startup: The central processing unit controls the second electronic expansion valve 14 to open. Part of the high-temperature liquid refrigerant is diverted from the first Y-type tee 11 to the auxiliary cooling circuit. After being throttled by the second electronic expansion valve 14, the low-temperature refrigerant evaporates and absorbs heat in the evaporation side channel of the system stabilizer 19. Since the system stabilizer 19 is a heat exchanger, it has independent condenser-side flow channel 27 and evaporator-side flow channel 28. The main circuit refrigerant flows in the condenser-side flow channel 27, and the auxiliary circuit refrigerant flows in the evaporator-side flow channel 28. By utilizing the low-temperature heat absorption of the auxiliary circuit, the temperature of the main circuit refrigerant is reduced, thereby lowering the suction temperature of compressor 1 and preventing compressor 1 from overheating.

[0038] Based on feedback signals from the return gas temperature sensor 33 and the exhaust gas sensor 4, the central processing unit dynamically and collaboratively adjusts the opening ratio of the first electronic expansion valve 41 and the second electronic expansion valve 14. Through this coordinated control, the exhaust temperature of the compressor 1 is strictly controlled below 115°C, effectively preventing the compressor from shutting down due to overheating protection.

[0039] In summary, this invention solves the problems of low efficiency and frequent shutdowns of traditional kitchen air conditioners in high-temperature environments through improved physical structure design and intelligent control using AI algorithms.

[0040] Furthermore, the technical solutions of the various embodiments of the present invention can be combined with each other, but only if they are feasible for those skilled in the art. If the combination of technical solutions is contradictory or cannot be implemented, it should be considered that such combination of technical solutions does not exist and is not within the scope of protection claimed by the present invention.

[0041] The above-described embodiments are merely illustrative of several implementations of the present invention, and while the descriptions are specific and detailed, they should not be construed as limiting the scope of the present invention. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of the present invention, and these modifications and improvements all fall within the scope of protection of the present invention. Therefore, the scope of protection of the present invention should be determined by the appended claims.
