Real Case of Lanchang 2HP Commercial Kitchen Air Conditioner Solving High Temperature for Small Catering Stores in Chongqing

Chongqing is known as a furnace city. In midsummer, extreme heat and high humidity create sweltering working conditions. Small noodle shops and local stir-fry restaurants feature cramped, enclosed back kitchens. Heavy-oil cooking plus continuous exhaust negative pressure turn kitchens into steaming saunas. This case targets a community stir-fry restaurant in downtown Chongqing with a 16-square-meter kitchen, two high-heat woks and two shift chefs serving local rice bowls and home-style dishes. Restricted by limited space and tight budget, the store’s former household air conditioner failed to fit Chongqing’s humid kitchen, and the owner adopted Lanchang 2HP commercial kitchen air conditioner to eliminate heat troubles once and for all.

Real Pain Points of the Restaurant

1. Extreme muggy heat causes high staff turnover and low cooking efficiency Outdoor temperature exceeds 40℃ in Chongqing’s summer, and the perceived temperature near stoves hits 46℃. Combined heat and humidity soak chefs’ uniforms all day long, leading to frequent resignations from June to September. High heat drains chefs’ stamina, slowing stir-frying and seasoning during lunch and dinner rushes, triggering customer complaints and hurting revenue.
2. Household air conditioners cannot withstand harsh kitchen conditions with high maintenance costs The store previously installed a 1.5HP household wall-mounted unit. After only 40 days, thick grease fully blocked filters and evaporators, cutting cooling performance by 60%. Household compressors only tolerate ambient temperature up to 35℃ and often shut down from overheating during meal peaks. Deep disassembly cleaning cost 160 RMB per service, costing nearly 1,000 RMB in three summer months, and frequent maintenance interrupted daily business.
3. Exhaust negative pressure wastes cool air and creates uneven cooling Full-time exhaust fans generate strong negative pressure. Scattered air output of ordinary AC gets most cold air sucked away by exhaust hoods, leaving cooking stations sweltering and prep corners uncooled. The unit ran at full load around the clock with surging electricity bills.
4. Core demands of small catering stores: compact unit to save counter space; high temperature and heavy oil resistance to cut cleaning frequency; directional air supply to retain cool air; moisture-proof design for Chongqing’s humid rainy season; energy-saving performance and responsive local after-sales service without disrupting peak dining hours.

On-site Survey & Customized Installation Solution

Lanchang engineers measured the narrow kitchen layout and exhaust air volume. Considering the small restaurant’s budget, we selected Lanchang 2HP wall-mounted high-static-pressure commercial kitchen air conditioner with targeted station cooling design:

1. Compact wall-mounted installation with directional air ducts to reduce cold air loss Side wall mounting saves limited counter space. Two separate short insulated ducts deliver cool air straight to the 1.5-meter working zone of two chefs. Air pipelines bypass core negative pressure zones of exhaust hoods to avoid massive cold air waste and realize concentrated cooling in narrow kitchens.
2. Unit optimized for Chongqing’s humid, heavy-oil kitchens Equipped with T3 high-temperature resistant commercial compressor, the unit maintains stable cooling under ambient temperature up to 60°C. Its 5-layer composite oil-proof filter and nano ceramic oil-repellent evaporator reduce grease adhesion by 70%. Daily maintenance only requires simple filter rinsing without frequent full disassembly. The anti-rust casing resists moisture and corrosion for Chongqing’s long humid plum rain season.
3. Energy-saving variable frequency to cut power expenses for small businesses Intelligent frequency conversion automatically lowers power output during off-peak hours, cutting monthly power consumption by 16% compared with the old household air conditioner and easing long-term electricity costs for small catering stores.
4. Local after-sales guarantee covering all downtown Chongqing Service outlets are distributed across the main urban area. 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 in daytime and 24-hour emergency repair at night, scheduled outside lunch and dinner peak hours.

Actual Operation Effect After Installation

Post-commissioning tests show the temperature at cooking stations stabilizes at 25℃, eliminating sticky swelter completely. Staff turnover caused by heat is greatly reduced, cooking efficiency rises by 14%, and summer maintenance costs drop by 80%. Featuring small size and high cost performance, Lanchang 2HP model perfectly fits 15–22㎡ back kitchens of noodle shops, stir-fry stores and string restaurants across Chongqing. It has become the mainstream renovation solution for small community catering outlets with heat problems, and the store owner has recommended Lanchang equipment to many nearby catering peers.
