【项目背景：当山城热浪遇见巴渝风味】

重庆，这座依山而建的直辖市，不仅以“8D魔幻城市”闻名于世，更有着独特的气候脾性。重庆属亚热带湿润季风气候，夏季酷热难耐，素有“长江四大火炉”之称，极端最高气温可达44℃以上；冬季则多雾湿润，全年相对湿度高达80%左右，静风频率高，是全国日照最少的地区之一。这种闷热潮湿的气候，对餐饮场所的通风降温提出了极高要求。

而“老家柴房”作为川渝餐饮的一张文化名片，凭借地道的柴火菜和浓郁的乡土情怀，在国内中部地区开设了多家连锁门店。它以“外婆厨房里的炊烟味”为情感纽带，让食客在都市中寻回记忆里的田园味道。本次项目不仅是味觉的回归，更是一次就餐环境的升级挑战。

【现场诊断：别有洞天的就餐空间】

该店为一栋钢筋混凝土框架结构的大平层，单层面积约1500平方米，层高3.5米。现场勘查时，我们被独特的装修风格吸引：

1、半开放式墙体设计：离地1.5米以下采用竹编镂空墙，既保证了通风透光，又营造出朴素的乡野情趣；

2、大面积采光窗：1.5米以上安装大面积玻璃窗，引入充足自然光；

3、全竹家具：餐厅内的餐桌椅全部采用竹制品，与整体风格浑然一体。

然而，这种富有设计感的空间，对温度调节提出了棘手难题：镂空墙导致空间并非完全密闭，若采用传统空调，冷气会迅速外泄，不仅造成巨大的能源浪费，设备也难以达到设定温度。如何在保留建筑美学的同时，为食客提供清凉舒适的就餐环境，成为方案设计的核心。

【瑞峰方案：屋顶上的“隐形降温卫士”】

面对这一挑战，瑞峰环保制冷的方案设计人员深入分析多方因素：

1、地理环境因素：重庆夏季高温持续时间长，且空气湿度大，需要降温设备兼具通风换气功能，避免“闷蒸感”；

2、建筑结构因素：镂空墙导致室内外空气交换频繁，传统空调不适用，必须采用开放式降温思路；

3、视觉美学因素：餐饮店门面形象至关重要，设备安装不能破坏整体观感；

4、承重与安全：屋顶为钢筋混凝土结构，承重力充足，具备设备上顶条件。

基于以上分析，我们创造性提出“屋顶侧出风冷风机+风管定向输送”方案。

我们将多台侧出风蒸发式冷风机稳固安装在屋顶承重梁位置，利用设备“水蒸发吸热”的物理原理——新鲜空气经过湿润的湿帘，水分子吸收空气中热量而蒸发，从而实现5-15℃的降温幅度。这一过程不采用压缩机，无氟利昂，耗电量仅为传统空调的1/8-1/10，节能环保。

更为巧妙的是，我们采用180度可回转风管，精准对接玻璃窗开口，将处理后的冷风源源不断引入室内。这种设计有三大优势：

1、避免破坏外立面：设备隐藏于屋顶，从街面视角完全看不到机组，守护餐饮店的视觉美感；

2、正压送风排浊气：冷风机持续送入新风，使室内形成微正压，将油烟味、浊气通过竹编墙缝隙自然排出，保持空气清新；

3、远距离均匀布风：3.5米层高利于冷空气自然沉降，配合专业风管设计，冷风可均匀覆盖1500平米每个角落。

【效果反馈：凉风里的烟火气】

工程竣工后，店内环境得到显著改善：

盛夏时节，当户外热浪滚滚，踏入老家柴房的食客却能感受到清风拂面的惬意。竹编墙外是山城的炽热阳光，竹墙内是凉风习习与柴火鸡的浓香。业主惊喜地发现，即便在午后用餐高峰期，店内温度依然保持在人体舒适范围，且空气流通不浑浊。

更令人欣慰的是，食客满意度明显提升，不少回头客反馈“坐在竹编墙边也不觉得热，风吹着很自然，不像空调风那样刺骨”。这恰恰印证了蒸发式降温换气机组的核心优势——保持空气湿润清新，避免“空调病”困扰。

【案例延伸：不止于餐饮，更是开放式大空间的解题思路】

此次老家柴房餐饮店工程的圆满交付，不仅是瑞峰在餐饮业态的又一成功案例，更深刻说明我们具备应对开放式大空间的综合实战能力。

事实上，竹编墙、镂空窗、大棚厂房、体育场馆……这些半开放式或高大空间，恰恰是蒸发式冷风机发挥优势的主战场。瑞峰公司通过精准的负荷计算、科学的设备选型、巧妙的风路设计，将设备效能最大化，既守住建筑原有的美学风格，又赋予空间舒适的体感温度。

我们相信，通风降温不是设备的堆砌，而是对空间、气候与人居体验的深度理解。 瑞峰环保制冷，愿为更多餐饮、制造、公共场馆提供量身定制的降温方案，让每一度凉风都恰到好处。

【 Project Background: When the heat wave of the mountain city meets the flavor of Bayu 】

Chongqing, a municipality built along the mountains, is not only known as the "8D Magic City", but also has a unique climate and temperament. Chongqing belongs to the subtropical humid monsoon climate, with unbearable hot summers and is known as the "Four Great Furnaces of the Yangtze River", with extreme maximum temperatures reaching over 44 ℃; In winter, it is foggy and humid, with a relative humidity of around 80% throughout the year and a high frequency of calm winds, making it one of the areas with the least sunshine in the country. This hot and humid climate places extremely high demands on ventilation and cooling in catering establishments.

As a cultural calling card of Sichuan Chongqing catering, 'Laojia Chaifang' has opened multiple chain stores in central China with its authentic firewood dishes and strong local sentiment. It uses the scent of cooking smoke from grandma's kitchen as an emotional bond, allowing diners to rediscover the rural flavor of their memories in the city. This project is not only a return to taste, but also a challenge to upgrade the dining environment.

On site diagnosis: A unique dining space

The store is a large flat floor with a reinforced concrete frame structure, with a single floor area of approximately 1500 square meters and a floor height of 3.5 meters. During the on-site inspection, we were attracted by the unique decoration style:

1. Semi open wall design: Bamboo woven hollow walls are used below 1.5 meters above the ground, ensuring ventilation and light transmission while creating a simple rural atmosphere;

2. Large area lighting windows: Install large glass windows over 1.5 meters to introduce sufficient natural light;

3. All bamboo furniture: The dining tables and chairs in the restaurant are all made of bamboo products, seamlessly integrating with the overall style.

However, this design rich space presents a tricky problem for temperature regulation: hollow walls result in a space that is not completely sealed, and if traditional air conditioning is used, the cold air will quickly leak out, causing huge energy waste and making it difficult for equipment to reach the set temperature. How to provide diners with a cool and comfortable dining environment while preserving architectural aesthetics has become the core of the design plan.

Ruifeng Plan: "Invisible Cooling Guardian" on the Roof

Faced with this challenge, the design team of Ruifeng Environmental Protection Refrigeration deeply analyzed multiple factors:

1. Geographical environmental factors: Chongqing has a long duration of high temperatures and high air humidity in summer, requiring cooling equipment with ventilation and air exchange functions to avoid the feeling of stuffiness;

2. Architectural structural factors: Hollow walls lead to frequent indoor and outdoor air exchange, traditional air conditioning is not suitable, and an open cooling approach must be adopted;

3. Visual aesthetic factors: The facade image of a restaurant is crucial, and equipment installation should not damage the overall appearance;

4. Load bearing and safety: The roof is made of reinforced concrete structure, with sufficient load-bearing capacity and equipment roof conditions.

Based on the above analysis, we creatively propose a "roof side air outlet cold air fan+duct directional conveying" solution.

We will install multiple side outlet evaporative air coolers firmly at the load-bearing beam position on the roof, utilizing the physical principle of "water evaporation absorbs heat" - fresh air passes through a moist curtain, and water molecules absorb heat from the air and evaporate, thereby achieving a cooling range of 5-15 ℃. This process does not use a compressor, there is no fluorine, and the power consumption is only 1/8-1/10 of traditional air conditioners, which is energy-saving and environmentally friendly.

Even more cleverly, we use 180 degree rotatable air ducts that precisely connect to the glass window openings, continuously introducing processed cold air into the room. This design has three major advantages:

1. Avoid damaging the exterior facade: The equipment is hidden on the roof, and the unit cannot be seen from the street view, safeguarding the visual beauty of the restaurant;

2. Positive pressure air supply and exhaust of turbid air: The air cooler continuously sends fresh air to create a slight positive pressure inside the room, naturally expelling the smell of oil and smoke and turbid air through the gaps in the bamboo woven wall, keeping the air fresh;

3. Long distance uniform air distribution: A height of 3.5 meters is conducive to the natural settlement of cold air, and with professional air duct design, cold air can evenly cover every corner of 1500 square meters.

【 Effect feedback: Fireworks in the cool breeze 】

After the completion of the project, the store environment has been significantly improved:

In the hot summer season, when the outdoor heat waves roll in, diners who step into their hometown's wooden house can feel the comfort of the gentle breeze brushing their faces. Outside the bamboo woven wall is the scorching sunshine of the mountain city, while inside the bamboo wall is the cool breeze and the strong aroma of wood turkey. The owner was pleasantly surprised to find that even during the peak afternoon dining period, the temperature inside the restaurant remained within a comfortable range for the human body, and the air circulation was not turbid.

What is even more gratifying is that the satisfaction of diners has significantly improved, and many returning customers have given feedback that 'sitting by the bamboo woven wall doesn't feel hot, the wind blows naturally, not as piercing as the air conditioning wind'. This precisely confirms the core advantage of evaporative cooling and ventilation units - keeping the air moist and fresh, avoiding the trouble of "air conditioning diseases".

[Case extension: not only for catering, but also for solving problems in open large spaces]

The successful delivery of the Chaifang restaurant project in our hometown is not only another successful case for Ruifeng in the catering industry, but also a profound demonstration of our comprehensive practical ability to cope with open large spaces.

In fact, bamboo woven walls, hollow windows, greenhouse factories, sports venues... these semi open or tall spaces are precisely the main battlefield for evaporative air coolers to exert their advantages. Ruifeng Company maximizes equipment efficiency through precise load calculation, scientific equipment selection, and clever wind path design, while preserving the original aesthetic style of the building and endowing the space with a comfortable sensory temperature.

We believe that ventilation and cooling are not the stacking of equipment, but a deep understanding of space, climate, and living experience. Ruifeng Environmental Refrigeration is willing to provide customized cooling solutions for more catering, manufacturing, and public venues, ensuring that every degree of cool breeze is just right.
