Real Installation Case of Lanchang 3HP Commercial Kitchen Air Conditioner at Miji Restaurant, Wuxi, Jiangsu

Basic Store Information

Miji Restaurant is a local home-style restaurant in Wuxi. Its 32-square-meter back kitchen has six independent working stations, equipped with four high-heat woks, one steam oven and one cold dish prep counter. Six staff work simultaneously during busy lunch and dinner hours. Wuxi features humid and muggy plum rain seasons. Continuous heat from kitchen stoves and powerful exhaust fans create strong negative pressure all year round. The store previously adopted a household 3HP floor-standing air conditioner, which brought four major troubles: uneven cooling effect, grease clogging, severe cold air loss and inconsistent temperature across different stations. High staff turnover followed, so the restaurant urgently required a dedicated cooling system with one single unit covering all six working positions.

Real Pain Points & Core Demands

1. Uneven temperature and persistent swelter across six stations: The old household air conditioner only cooled two nearby woks, while the steam oven and cold dish station stayed above 44°C all day long. All six kitchen staff worked in soaked uniforms in summer, many resigned every month with rising recruitment costs. High heat slowed cooking speed and triggered more customer complaints about long waiting times during peak hours.
2. Household air conditioners cannot withstand heavy lampblack and high temperature, leading to high maintenance costs: Heavy cooking grease fully clogged filters and evaporators of the household AC after only two months, cutting cooling capacity by half. Ordinary compressors frequently shut down for overheat protection during meal rushes. The store paid 200 RMB for each deep disassembly cleaning twice a month, costing over 4,000 RMB per year in maintenance fees.
3. Massive cold air loss due to exhaust negative pressure and high energy consumption: Undirected air supply let most cool air get sucked away by exhaust hoods, forcing the unit to run at full load with soaring monthly electricity bills.
4. Core requirements of the restaurant: One single unit to evenly cool all six stations; directional air ducts to eliminate cold air waste; strong oil resistance to cut cleaning frequency; moisture-proof design for Wuxi’s humid climate; local rapid after-sales service without disrupting business peaks.

On-site Survey & Customized Installation Solution

Lanchang professional engineers measured heat sources, exhaust air volume and layout of six stations on site. We selected the Lanchang 3HP high-static-pressure ducted commercial kitchen air conditioner with a one-main-unit-six-air-outlet directional air supply scheme to cool all six positions at once:

1. Balanced multi-duct air supply covering six stations fully: The indoor unit is ceiling-mounted to save operating space. Six independent insulated air ducts lead to dedicated jet air outlets for each station. Air vents target chefs’ 1.5-meter standing zones away from exhaust negative pressure areas, delivering cool air directly to staff without blowing on raw ingredients to avoid spoilage, realizing uniform cooling for all six working positions.
2. Unit optimized for harsh kitchen environments: Equipped with a T3 high-temperature resistant professional compressor, the unit operates stably under ambient temperature up to 60°C. Its 6-layer composite oil-proof filter and nano oil-repellent evaporator reduce grease adhesion by 70%. Daily maintenance only requires filter rinsing instead of frequent full disassembly cleaning. The stainless steel casing resists moisture and rust, perfectly fitting Wuxi’s humid plum rain weather.
3. Energy-saving variable frequency control: The intelligent frequency conversion system automatically adjusts power output based on passenger flow, cutting monthly power consumption by 19% compared with the original household air conditioner and lowering long-term electricity costs.
4. Local after-sales guarantee in Jiangsu: Exclusive service outlets are available in Wuxi. The unit enjoys a 3-year full-machine warranty and a 5-year warranty for core components. On-site maintenance is available within 4 hours on workdays and 24-hour emergency support at night to ensure uninterrupted business operation.

Actual Operation Effect After Installation

Post-commissioning tests show the temperature of all six working stations stabilizes at 24-26°C without overheating dead corners. Staff turnover caused by high temperature is largely resolved, cooking efficiency rises by 17%, and customer complaints drop significantly. Annual cleaning and maintenance costs are reduced by 85%. One single 3HP unit fully meets cooling demands of six stations with outstanding cost performance. This solution has become a benchmark renovation plan for medium-sized local restaurants with multiple working stations in Wuxi. The owner of Miji Restaurant has recommended Lanchang commercial kitchen air conditioners to many nearby catering peers.
