For small and medium restaurants (fast food, hotpot, coffee, bakery, noodle shops, etc.),Concentrated load from kitchen refrigerators, range hoods and A/C, offering a complete energy-saving solution based on the Zhijiexin ZX-01 AI Intelligent Power Loss Regulator.
Understand the bill's makeup first to see where the savings are. The table below estimates the electricity makeup of a typical small/medium restaurant (30–80 m², ¥3,000–5,000/month).
| Equipment type | Monthly usage (kWh) | Monthly bill (¥) | Share | Savings potential |
|---|---|---|---|---|

| 💨 Range hood | 300-500 | 240-400 | 8-10% | High (inductive load) |
| ❄️ Dining-area A/C | 800-1500 | 640-1200 | 20-30% | High (inductive load) |
| ❄️ Kitchen A/C | 200-400 | 160-320 | 5-8% | High (inductive load) |
| 💡 Lighting | 200-400 | 160-320 | 5-8% | Low (resistive load; LED already efficient) |
| 🍚 Rice cookers / steamers / warming tables | 400-800 | 320-640 | 10-15% | Low (resistive load) |
| 📺 POS / surveillance / audio | 50-150 | 40-120 | 1-3% | Low (low power) |
| 🔌 Other | 200-500 | 160-400 | 5-10% | — |
| Total | 3,000–5,000 kWh | ¥2,400–4,000 | 100% | The main savings potential is in inductive loads |
💡 Key insight:In a restaurant's electricity bill,Refrigerators + range hoods + A/C (dining area and kitchen) together account for 50–70%. These are allinductive load, generate large reactive currents. Most ordinary restaurants have a power factor between 0.6 and 0.8, meaning 30–40% of the current is wasted.This is the biggest opportunity for savings.
Based on mature reactive-power compensation engineering—not some gimmick, just physics.
Refrigerator compressors, range-hood motors, A/C compressors and similar equipment generate large reactive currents when running. This current does no useful work but takes up line capacity, increases conductor heating, and—for commercial and industrial users—can incur power-factor penalty charges.
The device connects in parallel on the distribution-cabinet busbar and uses AI algorithms to monitor reactive-power levels, harmonics and load changes in real time. It replaces no existing equipment and doesn't affect the shop's normal usage.
Based on real-time monitoring data, it supplies reactive-power compensation locally to the system—'containing' the reactive current near the compensation point instead of letting it travel back and forth in the lines. Line losses fall, transformer capacity is freed, and the power factor rises above 0.9.
Lower line losses mean less total power is needed to deliver the same active power (= a lower bill). For commercial and industrial users subject to the Measures for Power-Factor Adjustment of Electricity Charges, raising the power factor above 0.9 also directly reduces power-factor penalty charges and, in some cases, earns a rebate.
A 12-day daily-meter comparison, counterintuitively showing 'less power used with the A/C on.'
Comparison design:Two 12-day periods were chosen for comparison—December 6–17 (no device + no A/C) vs. January 6–17 (device installed + A/C on).Note: January is the more power-hungry condition(A/C on), so without the device, January should have used more power than December.
Core finding:In January the A/C was on (a more power-hungry condition), yet usage was 245 kWh lower than in December (no A/C). This 'reverse falsification'—using less power under more demanding conditions—is the most convincing proof of energy savings.
Savings estimate:At the local tariff of ¥0.8/kWh, an average daily saving of about 20 kWh saves ¥16/day, about ¥480/month,About ¥5,760–6,000/year saved. With a device investment of a few thousand yuan,Payback in under a year。

Zhijiexin's recommended configuration:One ZX-01 per ¥6,000 of monthly bill, supporting multi-unit parallel deployment. The final plan depends on the on-site survey.
💡 Actual savings rates vary with load characteristics, original power factor, tariff plan and other factors. We recommend a free on-site survey first.
5 frequently asked questions about restaurant energy saving.
Small and medium restaurants (30–80 m²) usually have monthly bills of ¥3,000–5,000, rising to ¥5,000–6,000 in peak season. It depends on floor area, foot traffic, opening hours, A/C intensity and other factors.
If electricity exceeds 3–5% of revenue, there's significant room to optimize, and an energy-saving upgrade is worth considering.
For restaurants on three-phase 380V commercial/industrial supply, installing a reactive-compensation power saver genuinely works.
Why:A restaurant's kitchen refrigerators, range hoods and A/C are all inductive loads with a generally low power factor (about 0.6–0.8), meaning 30–40% of the current is wasted. Reactive-compensation equipment can raise the power factor above 0.9.
Real cases:A 12-day comparison at Feihong Roujiamo's Hejiaying store in Xi'an measured 14.6% savings.
But note: plug-in home power-saver gadgets are 100% a scam—choose professional three-phase 380V cabinet-parallel equipment.
Based on Zhijiexin's real cases: Feihong Roujiamo's Hejiaying store saves about ¥6,000/year (on a ¥3,500/month base); other restaurant cases measured savings of ¥4,000–10,000/year. Payback is typically 6–12 months.
The exact savings amount depends on:(1) the monthly-bill base (a higher base means more savings); (2) the load structure (a higher share of inductive load means better results); (3) the tariff plan.
We recommend a free on-site survey before installation so an engineer can assess your specific savings potential.
No closure needed. The Zhijiexin ZX-01 connects in parallel in the distribution cabinet—it doesn't change the existing circuit, replace any equipment, or affect the shop's normal usage habits.
Installation process:
(1) on-site survey by an engineer (30 min, can be done during business hours);
(2) a brief power-off for wiring (1–2 hours, can be scheduled before/after hours or off-peak, e.g. before 9am or after 10pm);
(3) commissioning and a power-factor test (30 min).
The whole process doesn't require a full day of closure.
Zhijiexin's recommended sizing rule:One ZX-01 per ¥6,000 of monthly bill。
Configuration reference:
(1) ¥3,000–6,000/month (small fast-food, noodle shops): 1 unit;
(2) ¥6,000–12,000/month (mid-size restaurants): 2 units;
(3) ¥12,000–30,000/month (large restaurants, chain branches): 3–5 units in parallel.
Multiple units in parallel handle load distribution across different areas. Final configuration should be confirmed by an engineer after an on-site survey.
