【项目背景】

该项目位于浙江省宁波市江北区。宁波地处东海之滨，属亚热带季风气候，四季分明，夏季盛行东南风，高温、高湿、闷热天气持续时间长。受制于独特的地理位置，夏季空气湿度大，体感温度往往高于实际气温，闷热感尤为突出。

近期，该医院因就诊人数激增，现有用房已高度饱和。为缓解接诊压力、优化就医流程，医院在院内一处空旷的露天小广场上，临时搭建了可收纳式帐篷，用作挂号登记、预检分诊等辅助功能区。然而，在夏季高温天气下，帐篷内空气流通不畅，热量聚集，严重影响医护人员的工作效率和患者的就医体验，亟需一套高效、灵活、经济的通风降温解决方案。

【瑞峰解决方案】

针对该区域“临时性、开放式、人流量不固定”的特殊情况，瑞峰环保制冷的方案设计团队深入现场，综合考虑了地理气候、空间结构、人员流动、设备成本、安装周期等多重因素，摒弃了传统固定式空调需复杂布管、安装成本高的思路，创新性地提出了 “多台移动离心式冷风机 + 移动工业级永磁风扇” 的组合布置方案。

该方案的设计逻辑与优势如下：

1、精准应对人流变化，灵活机动： 医院人流量具有明显的波峰波谷特征。移动式机扇（即带万向轮的冷风机与工业大风扇）的最大优势在于其“灵活性”。在就诊高峰期，可集中布置多台设备，快速形成大范围的降温区域；在人流减少或区域功能调整时，可轻松移至其他需要的地方，甚至收纳入库，真正实现“即用即开，闲时即藏”，完全匹配帐篷区的临时属性。

2、因地制宜，利用“自然风”原理改善环境： 帐篷为开放式结构，不适合使用密闭式制冷的中央空调。我们选用的移动离心式冷风机，运用的是“水蒸发吸热”这一自然物理原理（即水分蒸发带走空气中热量的过程），能将室外新鲜空气经过降温后送入帐篷，源源不断地制造出湿润、清凉、含氧量高的清新冷风。而移动工业级永磁风扇，则通过直径超过1米的大型扇叶，驱动超大面积的空气流动，产生强劲的“类自然风”，加速人体表面汗液蒸发，从而实现立竿见影的降温体感。

3、成本可控，经济高效： 相比于安装固定式空调系统所需的设备采购、电力增容、管道铺设等高昂的前期投入，移动式设备几乎是“零安装成本”。不仅设备采购单价亲民，其运行能耗也远低于传统压缩机空调。对于医院临时性、季节性的需求而言，这种方案最大限度地节省了项目开支，将经费用在了刀刃上。

4、效果显著，以人为本： 方案实施后，帐篷内的闷热感被一扫而空。冷风机带来的清新湿润气流，配合工业大风扇的强劲微风，共同营造出一个“空气常新、体感舒适”的局部环境。清新的“自然风”不仅有效避免了传统空调房间的憋闷感，更保障了长时间在岗的医护人员的身心健康，同时也让前来就诊的患者感受到了一份清凉与关怀，赢得了院方领导及现场使用者的一致好评。

【项目延伸与能力体现】

此次瑞峰公司承接的虽是医院的临时区域项目，但其背后所体现的业务逻辑与技术能力，却具有广泛的可复制性和延展性。类似的场景，如大型室外临时核酸检测点、建筑工地工人休息区、户外文体活动集会点、工厂车间高温岗位、物流仓储分拣区等，凡是在特殊空间、特殊使用场景下存在临时或局部通风降温需求的，瑞峰均能提供量身定制的综合解决方案。

本项目的成功实施，再次证明了瑞峰环保制冷不仅具备专业的通风降温设备，更拥有针对复杂环境的综合选型能力、方案设计能力以及对项目成本的精湛控制能力。我们坚信，因地制宜的智慧方案，往往比昂贵的固定设施更具实际价值。

[Project Background]

The project is located in Jiangbei District, Ningbo City, Zhejiang Province. Ningbo is located on the coast of the East China Sea, with a subtropical monsoon climate and distinct four seasons. In summer, southeast winds prevail, and high temperatures, high humidity, and hot weather persist for a long time. Due to its unique geographical location, the air humidity in summer is high, and the perceived temperature is often higher than the actual temperature, making the stuffiness particularly prominent.

Recently, due to a significant increase in the number of patients seeking treatment, the hospital's existing facilities have become highly saturated. In order to alleviate the pressure of receiving patients and optimize the medical process, the hospital has temporarily set up a portable tent in an open outdoor small square inside the hospital, which is used as an auxiliary functional area for registration, pre examination and triage. However, in the hot summer weather, the air circulation inside the tent is poor and heat accumulates, seriously affecting the work efficiency of medical staff and the medical experience of patients. An efficient, flexible, and economical ventilation and cooling solution is urgently needed.

Ruifeng Solution

In response to the special situation of "temporary, open, and variable pedestrian flow" in the area, the design team of Ruifeng Environmental Protection Refrigeration went deep into the site and comprehensively considered multiple factors such as geographical climate, spatial structure, personnel flow, equipment cost, and installation cycle. They abandoned the traditional fixed air conditioning that requires complex pipe layout and high installation cost, and innovatively proposed a combination layout plan of "multiple mobile centrifugal air coolers+mobile industrial grade permanent magnet fans".

The design logic and advantages of this scheme are as follows:

1. Accurately responding to changes in abortion and being flexible: The hospital's flow of people has obvious peaks and valleys. The biggest advantage of mobile fans (i.e. air coolers with universal wheels and industrial fans) is their "flexibility". During peak medical periods, multiple devices can be centrally deployed to quickly form a large-scale cooling area; When the flow of people decreases or the area functions are adjusted, it can be easily moved to other places where it is needed, and even stored in the warehouse, truly realizing the "ready to use and open, hide when idle", fully matching the temporary nature of the tent area.

2. Adapt to local conditions and use the principle of "natural wind" to improve the environment: tents have an open structure and are not suitable for central air conditioning with closed refrigeration. The mobile centrifugal air cooler we have chosen utilizes the natural physics principle of "water evaporation absorbs heat" (i.e. the process of water evaporation taking away heat from the air), which can cool the outdoor fresh air and send it into the tent, continuously producing moist, cool, and high oxygen content fresh air. Mobile industrial grade permanent magnet fans, on the other hand, use large fan blades with a diameter of over 1 meter to drive a large area of air flow, generating strong "natural like wind" that accelerates the evaporation of sweat on the surface of the human body, thereby achieving immediate cooling sensation.

3. Cost controllable and economically efficient: Compared to the high upfront investment required for equipment procurement, power capacity expansion, and pipeline laying for installing fixed air conditioning systems, mobile equipment has almost zero installation costs. Not only is the equipment procurement unit price affordable, but its operating energy consumption is also much lower than traditional compressor air conditioners. For the temporary and seasonal needs of hospitals, this solution maximizes project cost savings and puts the expenses on the cutting edge.

4. Significant effect, people-oriented: After the implementation of the plan, the stuffiness inside the tent was swept away. The fresh and humid airflow brought by the air cooler, combined with the strong breeze of the industrial fan, creates a local environment of "fresh air and comfortable feeling". The fresh 'natural wind' not only effectively avoids the stuffiness of traditional air-conditioned rooms, but also ensures the physical and mental health of medical staff who have been on duty for a long time. At the same time, it also allows patients who come for treatment to feel cool and cared for, winning unanimous praise from hospital leaders and on-site users.

Project Extension and Capability Demonstration

The temporary area project undertaken by Ruifeng Company this time is a hospital project, but the business logic and technical capabilities reflected behind it have extensive replicability and scalability. For similar scenarios, such as large outdoor temporary nucleic acid testing points, worker rest areas on construction sites, outdoor cultural and sports activity gathering points, high-temperature positions in factory workshops, logistics warehousing sorting areas, etc., Ruifeng can provide customized comprehensive solutions for any temporary or local ventilation and cooling needs in special spaces and special usage scenarios.

The successful implementation of this project once again proves that Ruifeng Environmental Protection Refrigeration not only has professional ventilation and cooling equipment, but also has comprehensive selection ability, scheme design ability, and exquisite cost control ability for complex environments. We firmly believe that tailored smart solutions often have more practical value than expensive fixed facilities.
