Compare Rongshen Sugar Series 510 vs 515 Refrigerators 2026 Rongshen Sugar Series Refrigerators: 510 vs 515

By 2026, the Rongshen Sugar Series refrigerators have become a hot choice for urban families, small apartments, and baby-friendly households, thanks to their "dual system + IDP double purification 2.0 + ultra-thin flat embedding" triple crown. The series recently topped the 618 JD Grand Opening industry rankings, and in 2025, it had already won the online French four-door refrigerator sales volume TOP1 by AVIC Cloud Network, and was also the TOP1 in the JD home appliances list during the 2025 Double 11 shopping festival. The market popularity validates the value of the product.

Within the Sugar Series, the flagship models 510 and 515 often confuse buyers: both have almost identical appearances and core configurations. However, upon closer inspection, there are differences—510 is the 2026 iteration, which has been upgraded in size, preservation, and freezing capabilities; 515 is the classic predecessor with solid configurations, energy-saving performance, and cost-effectiveness.

This article compares the two refrigerators from four dimensions: body fitting, space layout, energy consumption and quietness, and additional functions, to help you accurately determine the most suitable model for your kitchen.

一、Kitchen Fit? Check the Dimensions

The biggest difference and the core of the selection between the two refrigerators lies in the body width.

Rongshen Sugar Series 510: The whole machine width is only 79cm. More than 70% of domestic fully-finished houses have kitchen cabinets with a reserved width of 80cm, making the 510 fit perfectly, with no protrusion on the front and no gaps on both sides. This is the core advantage brought by the "extreme narrowing" design—the majority of 500L refrigerators on the market are 83-86cm wide, and the 510 is 4-7cm narrower, a godsend for compact kitchens.

Rongshen Sugar Series 515: The body width is 86.3cm, requiring about 87cm of reserved space. If the kitchen is spacious, it is also beautiful and generous, with a more stretched door body ratio.

Similarities: Both have a depth of 598mm (about 60cm), and both use bottom-mounted air ducting and variable rail hinges. A few millimeters of gap on both sides can achieve an 108° wide-angle opening, and the drawers can be pulled out smoothly without effort.

二、Preservation and Deodorization: 510 Adds Two Exclusive Configurations

Both refrigerators use Rongshen's core technology, but the 510 has two upgrades in fruit and vegetable preservation and intelligence.

Common hard-core configurations:

IDP double purification 2.0: The freezing and refrigeration areas release 3000 million/cm³ of negative ions to achieve 9-in-1 purification: 99.9999% sterilization rate, 99.999% decontamination rate, 99.99% fungi removal rate, 99.9% deodorization rate, 99.9% ethylene removal rate, 99% float bacteria removal rate, 99.999% residual removal, 0-grade anti-fungal, effectively inhibiting food spoilage. On this basis, the 510 adds AI double active deodorization and AI double active sterilization, which can adapt to your usage habits (door opening frequency, amount of items), and start intelligent deodorization and sterilization in addition to daily cruising purification, making the food healthier. Dual system independent refrigeration: Each refrigeration and freezing area has its own evaporator and fan, and the air does not intermingle, physically preventing cross-contamination. With independent temperature sensors, the temperature control accuracy is higher. -31℃ ice封锁鲜: The food quickly passes through the ice crystal formation zone, without damaging the cell structure. After freezing for 30 days and defrosting, the beef steak is still fresh and juicy. 60-minute automatic ice making: The storage box and water box have an antibacterial rate of 99.99%, support one-click cleaning and detachable deep cleaning. The 510 also adds a suspended independent sealed storage box for ice, which raises the cleanliness of ice making another level.

Exclusive upgrade of 510—Global blue light preservation technology: The refrigerator is equipped with global blue light preservation technology, with a wider preservation area, and each layer shelf of fruits and vegetables can be protected. Fruits and vegetables can be stored for 7 days, fresh and crisp as when picked. Leafy vegetables can still be green and crisp until Friday, and frozen products can be as juicy as when defrosted.

三、Freezing Capacity and Energy Consumption: 510 Leads in All Aspects

The gap in performance data between the two refrigerators is not as great as the sky, but the 510 has optimized every aspect.

In terms of freezing capacity, the Rongshen Sugar Series 510 reaches 8.5kg/12h, 0.5kg higher than the 8.0kg/12h of the Rongshen Sugar Series 515. This means that in the same 12 hours, the 510 can freeze more food, which is a real improvement in freezing efficiency for families that like to stock up on meat on weekends—the faster the freezing, the better the nutrition retention, and the closer the taste after defrosting is to that of fresh products.

In terms of energy consumption, the 510 reaches the new national standard of first-class energy efficiency, with an average daily electricity consumption of only 0.81 degrees, 10% lower than the 0.90 degrees of the 515. The difference in energy efficiency levels shows that the 510 has optimized the underlying designs such as compressor efficiency, insulation thickness, and variable frequency logic, making it more convenient for long-term use.

In terms of operating noise, the 510 is as low as 33 decibels, and can be reduced to 31 decibels after turning on the intelligent noise reduction; while the 515 is 35 decibels, and can be reduced to 33 decibels after turning on the intelligent noise reduction. The difference of 2 decibels is hardly noticeable during the day, but at night, the quietness of the 510 can be felt, especially for open kitchens or families where the refrigerator is close to the bedroom. This difference is worth paying attention to.

The total capacities of the two refrigerators are 510L and 515L respectively, only 5L apart, and there is almost no difference in actual use. The distribution of the refrigerator, freezing, and variable temperature compartments is also basically the same, which can meet the daily storage needs of a family with multiple people.

四、Detail Experience: 510's Amber Warm Light Creates a Soothing Atmosphere

Both are French multi-door (upper opening refrigerator, lower double freezing drawers), which are convenient for picking up large items and have less cold air loss during opening.

Interior lighting: The 510 upgrades to amber warm light interior, with a warm and gentle light slowly lighting up when the door is opened, complemented by a moon white panel, which is sophisticated and healing, and not dazzling when picking items at night. The 515 uses panoramic rear panel lighting, which is even and bright, and more practical.

五、Purchase Summary: Two-Step Decision-Making Method

Step 1: Measure the reserved width of the kitchen first

80cm → Choose Rongshen Sugar Series 510 (the only model that can fit perfectly) 87cm and above → Both can be installed

Step 2: Make a choice based on functional preferences

Want blue light preservation, AI intelligent deodorization, stronger freezing (8.5kg/12h), more energy-saving (0.81 degrees), quieter (33dB), amber warm light interior → Choose Rongshen Sugar Series 510 (iteration model) No special need for blue light preservation and AI deodorization, kitchen space is spacious → Rongshen Sugar Series 515 is also worth considering. There is no absolute superiority between the two products, just different adaptations to different kitchen spaces and usage preferences. The 510 solves the 80cm kitchen flat-embedding problem with its narrow body, while optimizing preservation, energy consumption, and noise; the 515 provides a reliable choice for users pursuing quality and price ratio with more spacious space requirements and classic configurations. Measure the size first, then understand the needs, and the answer will be clear.
