[Catering Ventilation and Cooling] Collection of Case Studies on Evaporative Air Cooler Window Installation Projects in Multiple Catering Individual Stores

Food is of paramount importance to the people, and food safety comes first. Noodle shops, fast food restaurants, stir fry shops, breakfast shops, hotpot restaurants, barbecue restaurants scattered throughout the streets and alleys are not only the creators of urban fireworks, but also the livelihoods of countless families, carrying the basic needs of daily food for the people. Ruifeng Environmental Protection Refrigeration has been deeply involved in the industry for many years, providing ventilation and cooling engineering services for hundreds of catering individual stores of different sizes and formats across the country, accumulating rich practical experience in "small space, high heat source, heavy oil fume, and strict cost control".

Project Background and Challenges

The target of this service is a number of unrelated catering self-employed households - there are noodle shops that mainly deal with Noodles in soup, fast-food restaurants that serve fast-paced meals, stir fried restaurants, busy breakfast shops in the morning, hot pot restaurants in all seasons, and barbecues with fireworks. Despite their diverse flavors, these shop owners face highly similar pain points: unbearable high temperatures in the kitchen or dining area, mixed fumes and heat, murky indoor air, and as small businesses, they are extremely sensitive to equipment procurement costs and subsequent electricity expenses.

In response to this common demand, the Ruifeng technical team did not promote expensive equipment in a one size fits all manner. Instead, they conducted on-site investigations in every store and tailored a cost-effective solution based on factors such as kitchen area, stove location, business hours, and heat source type, including an evaporative air cooler and a window style air duct uniform air supply system.

[Scheme Design and Core Highlights]

1. Zero occupancy installation, cleverly utilizing the space outside the window

Considering that small restaurants often have compact spaces and precious land, we innovatively hung and installed the main body of the evaporative air cooler on the outside of the window. This design completely unleashes the valuable operational and business space indoors - the noodle cooking area of the noodle shop, the steaming area of the breakfast shop, the side dish area of the small stir fry shop, the dining area of the hot pot shop, and the oven area of the barbecue shop - without any impact. The equipment operating noise is also isolated outdoors, ensuring normal operation of the shop.

2. The ultimate application of physical principles: combining cooling and ventilation effects

This system utilizes the natural physical principle of "water evaporation absorbs heat": when fresh outdoor air passes through a wet curtain moistened by a cooling fan, the moisture evaporates and absorbs heat from the air, thereby converting dry hot air into moist cool air.

1) Precise air supply: The processed cold air is guided to key positions such as the chef's operation area and dining area through customized window style air ducts, according to the actual layout of each store, to achieve uniform air supply.

2)  Positive pressure turbidity removal: Continuous injection of cold air creates a slightly positive pressure environment indoors. According to the principles of aerodynamics, this fresh airflow will act like an invisible "pusher", efficiently "squeezing" the oil fumes generated by the intense frying in the kitchen, the hot steam from the boiling soup, the stuffy and humid air emitted by the breakfast steamer, the rolling water vapor rising from the hot pot, and the most headache inducing charcoal smoke smell in the barbecue restaurant, along with the turbid air exhaled by customers, out of the room.

3) Significant effects: After installation, the environment of each store improved immediately - the chefs in small stir fry shops no longer sweat profusely, the pick-up areas in fast food restaurants are no longer stuffy and unbearable, and the heat wave around the steamer positions in breakfast shops has significantly dissipated; The misty "sauna" feeling in the hot pot restaurant has disappeared, and customers no longer wipe their sweat while eating; The smoky fire in the barbecue restaurant has significantly reduced, and the dining environment is much fresher, greatly improving the dining experience for customers. The improvement of employee work comfort and customers' willingness to sit for long periods of time indirectly bring more stable customer sources and higher turnover rates to shop owners.

3. Ultimate cost control, in line with the business needs of small stores:

1) Affordable equipment cost: Compared to central air conditioning or large environmentally friendly air conditioning, the purchase cost of evaporative air coolers is extremely low, which puts less pressure on small business owners.

2) Extremely low operating costs: no need for compressors (only relying on fans and water pumps to operate), power consumption is only about 1/8 of traditional air conditioners, and maintenance is simple, perfectly matching the demanding requirements of individual restaurants for "energy saving, durability, and less worry". For businesses such as barbecue and hot pot that require long-term and high-power ventilation, electricity cost savings are particularly significant.

Proof of Technology Extension and Service Capability

Although this service is provided to scattered individual catering stores, covering various formats such as noodle shops, fast food restaurants, stir fry shops, breakfast shops, hot pot restaurants, barbecue restaurants, etc., Ruifeng Company has demonstrated strong cross scenario analysis and summarization capabilities during the service process.

We deeply understand that no matter what the store sells, as long as there are five characteristics of "high temperature heat source, high oil fume/water vapor, dense personnel, limited space, and cost sensitivity", their ventilation and cooling needs have a high degree of commonality. And this feature not only exists in various small catering shops, but is also widely applicable to small factory workshops, school canteens, internet cafes, street stalls, temporary exhibition venues, and other scenarios.

Through the successful implementation of this batch of catering individual store projects, Ruifeng Company has fully demonstrated that we have:

1. Accurate diagnostic ability: able to quickly identify the distribution of heat sources, oil fume concentration, and air flow pain points in different spaces (whether it is barbecue with heavy oil fume or hot pot with heavy water vapor, the focus of the solution varies);

2. Flexible selection ability: Master the comprehensive performance and applicable scenarios of various equipment such as evaporative air coolers, negative pressure fans, and duct layouts. Do not blindly promote, only recommend the most suitable solution for the owner's budget and actual situation;

3. Refined construction capability: For old buildings and different wall structures, window installations can be securely completed to ensure safety, firmness, aesthetics, and durability.

Ruifeng Environmental Protection Refrigeration has been focusing on ventilation and cooling engineering for 16 years. Whether you are a breakfast shop, barbecue stall, or a factory workshop, as long as there is a problem of stuffiness, Ruifeng can provide you with the most suitable solution to solve your problems.
