Real Installation Case of Lanchang 5HP Commercial Kitchen Air Conditioner for Coconut Chicken Chain Store Owned by Mr. Zhan in Hainan

Hainan is a tropical island with long summers all year round, where air humidity stays above 85%. The kitchen environment is harsh with high temperature, heavy moisture and strong sea salt fog corrosion. Coconut chicken chain restaurants need continuous coconut soup boiling, fresh Wenchang chicken cutting and stir-frying side dishes. Full-power exhaust fans run all day and create strong negative pressure. Mixed water vapor and fine grease quickly clog ordinary air conditioners. Mr. Zhan, the person in charge of the chain brand, runs a 45-square-meter kitchen with six working zones including soup boiling, ingredient cutting and coconut opening stations, staffed by six shift workers. Two household floor-standing air conditioners failed to cool, resist moisture and repel grease. After comparing various equipment, he uniformly adopted Lanchang 5HP ducted commercial kitchen air conditioner. The renovation achieved outstanding overall performance and won unanimous recognition from kitchen staff.

Original Pain Points of the Restaurant

1. High temperature and humidity on the island lead to severe staff turnover Hainan stays sweltering all year. Constant heat steam from soup boilers pushes perceived temperature above 44℃ during lunch and dinner peaks. Staff’s uniforms stick to skin all shifts, causing fatigue, frequent transfers and resignations. High heat accelerates spoilage of fresh coconut meat and chicken, raising food loss and food safety risks.
2. Household air conditioners cannot withstand water vapor and salt fog with high maintenance costs Massive steam and grease from coconut soup boiling form thick sludge on filters and evaporators of household AC within one month, cutting cooling capacity by 55%. Salt in sea air rusts ordinary metal casings and causes water leakage. Household compressors overheat and shut down frequently during meal rushes. Twice monthly deep disassembly cleaning costs 230 RMB per service, with annual maintenance expenses over 5,500 RMB. Frequent repairs disrupt stable food supply for the chain store.
3. Exhaust negative pressure wastes cool air and causes uneven cooling Scattered air output of two household units lets most cold air get sucked away by exhaust hoods. Soup boiling zones remain extremely hot while inner cutting and coconut-opening stations barely receive cool air. Running two units round the clock results in sky-high monthly electricity bills.
4. Core demands of chain stores: One single 5HP unit to cover all six stations; moisture and salt fog resistance against water vapor and grease; directional air supply avoiding fresh raw ingredients; stable operation under Hainan’s year-round high temperature; local rapid after-sales service to sustain daily operation.

Customized 5P Installation Solution After On-site Survey

Lanchang engineers measured heat sources, exhaust air volume and the island’s humid, salty environment on site, and adopted concealed ceiling-mounted Lanchang 5HP high-static-pressure ducted air conditioner for full renovation:

1. Multiple independent air ducts deliver balanced targeted cooling The indoor unit is hidden on the ceiling, equipped with six insulated air ducts serving soup boiling, cutting and coconut-opening stations separately. Air outlets are set at 1.5-meter height away from fresh ingredient counters to prevent spoilage. Pipelines bypass core negative pressure zones of exhaust hoods to drastically reduce cold air waste and realize uniform temperature across the whole kitchen.
2. Unit optimized for harsh island kitchen conditions in Hainan Equipped with T3 ultra-high-temperature resistant commercial compressor, the unit runs stably under ambient temperature up to 60℃ in hot and humid conditions. Its 7-layer oil-water-proof composite filter and nano oil-repellent evaporator cut vapor and grease adhesion by 72%. The thickened 304 stainless steel casing resists sea salt fog corrosion, eliminating water leakage and rust caused by year-round heavy humidity in Hainan. Daily maintenance only requires simple filter rinsing without frequent full disassembly cleaning.
3. Energy-saving DC variable frequency control reduces power cost for chain brands Power output adjusts automatically based on passenger flow, cutting monthly power consumption by 24% compared with two household air conditioners and lowering long-term electricity expenses for multi-store chain brands.
4. Provincial-wide localized after-sales guarantee in Hainan Service outlets are located in Haikou and Sanya. The unit carries 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 overnight, avoiding operation interruption during tourist rush hours.

Actual Operation Effect After Installation

Post-commissioning tests show all kitchen stations maintain stable temperature of 24–26℃, completely eliminating sticky swelter and scorching heat around soup boilers. Staff working comfort improves greatly, staff turnover is largely resolved, food waste drops, cooking efficiency rises by 19%, and annual cleaning & maintenance costs fall by 86%. Highly satisfied with the cooling, moisture-proof and energy-saving performance, Mr. Zhan designated Lanchang 5HP as standard equipment for all new coconut chicken chain stores under his brand, and recommended the product to numerous local catering peers in Hainan.
