Bincheng style and the pursuit of quality in the hotel industry - Flexible cooling solution for outdoor landscape sheds with mobile fans in a well-known hotel in Dalian

This project is located in Dalian, a coastal city known as the "Pearl of the North". This place is located in the warm temperate zone of the northern hemisphere, with a temperate monsoon climate characterized by maritime features. There is no severe cold in winter and no extreme heat in summer, with distinct four seasons. It boasts a winding coastline of 2211 kilometers, with mountains and seas interdependent and pleasant scenery. Dalian, as an important port, trade and tourism city in Northeast China, attracts millions of domestic and foreign tourists every year with its romantic coastal roads, scattered squares, and rich tourism resources such as Jinshitan National Tourist Resort. For this tourist city, high-quality hotels are not only a harbor for tourists to relax, but also an important window to showcase the city's service image and cultural connotation. Their hardware facilities and service details directly affect the "retention" of tourists and the tourism reputation of the city.

[Project Background: Comfort Challenge Caused by Space Expansion]

The expansion hall is located inside a well-known hotel in Dalian city. In recent years, with the increasing popularity of the tourism market and the continuous growth of hotel customers, the core functional areas such as indoor banquet halls and conference rooms have approached saturation. To meet the diverse needs of more outdoor weddings, themed banquets, and business parties, the hotel made a decisive decision to build a fixed steel structure landscape greenhouse using an excellent open space in the courtyard.

The structure of the greenhouse is quite ingenious: the main body adopts a stable color steel frame, and the facade is embedded with a large area of transparent glass, which not only ensures sufficient natural lighting, but also introduces the outdoor urban scenery into the interior, achieving an unobstructed visual experience; The top adopts a lightweight soft waterproof fabric canopy, which not only effectively provides shade and rain protection, but also maintains the overall lightness of the building. However, this fully transparent structure faces severe ventilation and cooling challenges in summer - under direct sunlight, the greenhouse effect is easily formed by the accumulation of heat inside the shed. If not improved, it will greatly affect the dining and activity experience of guests.

Ruifeng Solution: Flexible Deployment, Intelligent Manufacturing of Comfortable 'Natural Wind'

In response to this special scenario, the design personnel of Ruifeng Environmental Protection Refrigeration went deep into the site to comprehensively analyze the climate characteristics of Dalian in summer, which are characterized by high humidity and less extreme heat but obvious stuffiness, the spatial characteristics of fully open greenhouses that require landscape views, and the actual needs of hotels for cost control of equipment investment and multifunctional utilization of the site. In the end, we abandoned the traditional fixed air conditioning system that required complex piping, damaged building structures, and high costs. Instead, we innovatively proposed a combination layout of "mobile centrifugal air coolers+mobile industrial grade large fans".

This design is mainly based on the following considerations:

1. Dealing with traffic uncertainty, mobile deployment shows its skills: the number of participants in outdoor activities in hotels has great uncertainty. Once traditional fixed equipment is installed, it cannot meet the flexible needs of activities of different scales. And our mobile fan is equipped with universal wheels at the bottom, truly realizing "plug and play, move as needed". When the venue is full, it is recommended to bring coolness and then move it back to the warehouse after closing, without occupying any space for daily flexible layout.

2. Empowered by physical principles, low-cost creation of "natural oxygen bars": Traditional compressor air conditioners often suffer from low efficiency and soaring energy consumption due to air loss in relatively open or semi open spaces. Our solution utilizes two major physical principles to achieve efficient cooling:

1) Evaporative heat absorption (air cooler): Mobile centrifugal air coolers utilize the natural physical phenomenon of "water evaporation absorbs heat". When hot air passes through a wet curtain soaked in water, the heat is absorbed and carried away by the moisture, thereby sending out cool, moist and fresh air. It can not only cool down by 5-12 ℃, but also maintain the freshness of the air, without the discomfort of traditional air conditioning.

2) Enhanced convection (industrial large fan): Industrial grade permanent magnet infinitely variable speed large fans with a diameter exceeding 1 meter produce a three-dimensional air supply effect similar to natural wind through slow and large-scale air agitation, accelerating the evaporation of sweat on the surface of the human body and bringing a cool feeling of 3-5 ℃ decrease in perceived temperature.

3. Improving environmental quality and assisting business efficiency: The centrifugal air cooler with high air volume works in conjunction with the large fan, greatly improving the stuffiness and heat sensation in the air coverage area. The flowing 'natural wind' ensures the freshness and circulation of the air in the expansion hall, allowing guests to enjoy delicious food and beautiful scenery while also feeling healthy and comfortable both physically and mentally. The environment has improved, and the utilization rate of the site has naturally increased. Whether it's a delicate afternoon tea or a romantic wedding at night, this place has become a sought after "feng shui treasure trove" for guests to book.

4. Ultimate cost control, saving customer expenses: The initial investment cost of mobile fans is much lower than that of central air conditioning systems with the same cooling capacity, and the energy consumption during later operation is extremely low (about 1/8 to 1/10 of traditional air conditioning), without the need to install complex pipeline lines and saving high installation and maintenance costs. While ensuring excellent cooling effect, we have truly reduced costs and increased efficiency for our customers.

Case extension and capability proof

The mobile fan layout solution provided by Ruifeng Environmental Protection Refrigeration for a fixed greenhouse in a hotel in Dalian, although the project itself is a fixed building, the core of its solution - "mobile flexible deployment" - successfully solved the comfort pain point caused by the variable functions of the fixed space. Its application scenarios are highly replicable and have promotional value, and can be widely extended to various similar places, such as:

1. Culture, Tourism, and Commerce: Temporary rest areas in scenic spots, stalls outside commercial streets, creative markets, beer festival greenhouses, and outdoor temporary exhibition halls.

2. Events and exhibitions: large-scale outdoor weddings, company team building and expansion, restaurants in tent camping sites, temporary command centers.

3. Industry and Logistics: Temporary operation points for large warehouses, maintenance workshops that require local cooling, and logistics sorting centers.

This project fully demonstrates that Ruifeng Company has the comprehensive equipment selection and scheme design capabilities for special spatial structures (such as steel structure glass sheds) and special usage scenarios (such as multifunctional uses and large fluctuations in pedestrian flow). We are good at breaking free from fixed thinking and not being limited to a "fixed" solution. Instead, we take the actual business needs of our customers as the core and extreme cost control as the criterion. We flexibly use mobile and modular innovative products to tailor the most suitable and economical ventilation and cooling solutions for every difficult place.
