Project Overview
Basic Store Information
Jiangcheng Hancai Restaurant in Wuhan specializes in authentic Hubei local cuisine. Its 42-square-meter back kitchen is equipped with 5 high-heat stir-fry stoves for Hancai, large steam braising ovens and cold dish prep areas, with 7 kitchen staff working simultaneously all day. Wuhan suffers sweltering hot summers and muggy plum rain seasons with high humidity. Heavy-oil high-temperature cooking generates concentrated heat sources, while full-power exhaust fans run all day long and create strong negative pressure. The restaurant previously installed two household 3HP air conditioners, which failed to withstand Wuhan’s extreme summer heat and brought multiple troubles in cooling, maintenance and power consumption. The restaurant urgently required a high-power single unit with dual-channel air supply to fully cool the whole kitchen.
Real Pain Points & Core Demands
- Steaming hot kitchen in Wuhan’s dog days leads to high staff turnover and low efficiency: The temperature near stoves hit 46-50℃ during lunch and dinner peaks, with combined stifling heat and high humidity. Chefs’ uniforms stayed soaked all shifts, causing monthly resignations of kitchen workers. Extreme heat drained chefs’ stamina, increased cooking mistakes, slowed order output and brought more customer complaints over long waiting times.
- Household air conditioners cannot fit heavy-grease kitchens and bring high maintenance costs: Heavy cooking grease from Hancai stir-frying clogged filters and evaporators of household air conditioners within one month, cutting cooling capacity by half. Ordinary compressors lacked high-temperature resistance and frequently shut down from overheating at noon. The store paid 220 RMB for each deep disassembly cleaning twice a month, costing over 5,000 RMB per year on maintenance.
- Severe cold air loss under exhaust negative pressure and uneven temperature distribution: Without targeted partition air ducts, most cool air was sucked away by exhaust hoods. Cooking stations remained sweltering while prep and steaming areas got weak cooling. Running two household units simultaneously resulted in sky-high monthly electricity bills.
- Core requirements of the restaurant: One single 5HP high-power unit with dual-channel partition air supply to cover both stir-fry stations and steaming prep zones; high static pressure ducts to penetrate exhaust negative pressure and reduce cold air waste; strong oil and moisture resistance to fit Wuhan’s humid climate; low long-term maintenance and energy-saving performance; local rapid after-sales service in Wuhan to avoid business disruption during meal peaks.
On-site Survey & Customized Dual-channel Solution
Lanchang professional engineers measured heat distribution, exhaust air volume and station layout on site. We adopted Lanchang 5HP high-static-pressure ducted commercial kitchen air conditioner with an innovative dual-channel partition air supply scheme to fully resolve Wuhan’s summer high-temperature troubles:
- Independent dual-channel air supply for full coverage without hot dead corners: The indoor unit is ceiling-mounted to save operating space, equipped with two separate insulated air ducts. The first channel targets 5 stir-fry stoves with multiple jet air outlets delivering cool air to chefs’ 1.5-meter working zones. The second channel covers steam ovens and cold dish prep areas, with independently adjustable airflow for both channels without mutual interference. Air ducts bypass core negative pressure zones of exhaust hoods to drastically cut cold air loss, balancing cooling for cooking and prep areas.
- Unit optimized for harsh kitchen conditions in Wuhan: Equipped with T3 ultra-high-temperature resistant commercial compressor, the unit maintains stable continuous cooling under ambient temperature up to 60°C. Its 7-layer composite oil-proof filter and nano ceramic oil-repellent evaporator reduce grease adhesion by 72%. Daily maintenance only requires simple filter rinsing without frequent full disassembly deep cleaning. The stainless steel casing resists moisture and rust, protecting the unit from long-term humid vapors during Wuhan’s plum rain season.
- Energy-saving DC variable frequency intelligent temperature control: Power output adjusts automatically based on lunch and dinner passenger flow, cutting monthly power consumption by 23% compared with the original two household air conditioners and lowering long-term electricity costs significantly.
- Localized after-sales guarantee in Hubei: Exclusive service outlets are stationed in Wuhan. The unit enjoys a 3-year full-machine warranty and a 5-year warranty for core components. On-site maintenance is available within 3 hours on workdays and 24-hour emergency repair at night to guarantee normal operation during lunch and dinner peaks.
Actual Operation Effect After Installation
Post-commissioning tests show the temperature at stir-fry stoves stabilizes at 24℃, while steaming and cold dish prep areas stay at 26℃. Uniform partition temperature control via dual channels eliminates all sweltering dead corners. Staff turnover caused by high temperature is largely resolved, overall cooking efficiency rises by 18%, and annual cleaning & maintenance costs drop by 88%. The single 5HP dual-channel solution perfectly fits medium and large Hancai and home-style restaurants with multiple working stations in Wuhan, becoming a benchmark renovation plan for local catering kitchens with high temperature issues. The owner of Jiangcheng Hancai Restaurant has recommended Lanchang commercial kitchen air conditioners to numerous Hubei cuisine peers nearby.
