Hot Pot Restaurant Kitchen Cooling Planning Guide: How to Use a Fresh Air Water-Cooled Fan and the Composition of an Air-Conditioning Water-Cooled Fresh Air Unit

In the catering industry, especially in hot pot restaurants, high temperatures, high humidity, and pervasive cooking fumes are the norm. Traditional central air conditioning or ordinary fans struggle to cope, while the combined solution of commercial kitchen air conditioning and water-cooled fresh air fans is becoming mainstream. This article will provide an in-depth analysis of the composition of air-conditioning water-cooled fresh air units, how to use a fresh air water-cooled fan, and practical recommendations for hot pot restaurant kitchen cooling planning, helping you create a cool, clean, and energy-efficient kitchen environment.

I. Why Do Hot Pot Restaurant Kitchens Need a Dedicated Cooling Solution?

The heat sources in a hot pot restaurant kitchen come not only from stoves but also from continuously boiling soup bases, steaming equipment, and dense foot traffic. In summer, kitchen temperatures often exceed 45°C with humidity near saturation, and ordinary air conditioners quickly fail due to grease blockage and corrosion. Therefore, targeted hot pot restaurant kitchen cooling planning is needed, with the core approach being the trinity of “cooling + ventilation + dehumidification.”

A common misconception is to install only exhaust fans, which results in excessive negative pressure that causes unstable stove flames and backflow of cooking fumes. The correct approach is to introduce water-cooled fresh air fans, which cool outdoor hot air through water cooling before delivering it into the kitchen, while simultaneously exhausting high-temperature cooking fumes to form directional airflow. This is why more and more hot pot restaurants are choosing to operate commercial kitchen air conditioning and water-cooled fresh air fans in tandem.

II. Analysis of the Composition of Air-Conditioning Water-Cooled Fresh Air Units

To understand how to use a fresh air water-cooled fan, one must first understand the composition of air-conditioning water-cooled fresh air units. A complete unit typically includes the following core components:

• Water-cooled heat exchanger (wet curtain/surface cooler): Uses water evaporation and heat absorption or chilled water circulation to cool air by 5-12°C. This is the heart of the water-cooled fresh air fan.
• Centrifugal fan: Provides sufficient air pressure to overcome duct resistance and deliver cool air to various workstations in the kitchen.
• Filtration system: Primary + medium-efficiency filtration to intercept grease particles and protect the heat exchanger from being clogged by oil.
• Water pump and water distribution system: Circulating water evenly wets the wet curtain to ensure heat exchange efficiency; some models are equipped with automatic water replenishment and drain valves.
• Control system: Temperature and humidity sensors, frequency converters, LCD panels to achieve automatic adjustment of air volume and water temperature.
• Housing and water collection tray: Anti-corrosion and anti-rust materials (such as powder-coated galvanized sheet or stainless steel) to collect and discharge condensate water.

Professional brands such as LCCFAIR also add UV sterilization modules and anti-oil coatings inside the unit to extend maintenance intervals. After understanding these components, you can better formulate hot pot restaurant kitchen cooling planning—for example, installing workstation air supply ducts above the stove area and setting up independent exhaust in the dishwashing area.

III. How to Use a Fresh Air Water-Cooled Fan? Key Operating and Maintenance Points

How to use a fresh air water-cooled fan directly determines the cooling effect and service life. The following is the standard operating procedure:

• Pre-start inspection: Confirm the water tank level, whether the wet curtain is moist, and whether the filter screen is clean. If using a chiller unit, check the water temperature setting (typically 7-12°C).
• Startup sequence: Turn on the fan first, then the water pump. Avoid running the fan dry when the wet curtain is not wet, which would cause cooling failure.
• Air volume adjustment: Adjust the frequency converter based on the kitchen heat load. During peak hours at a hot pot restaurant, run at full speed; during off-peak hours, reduce frequency to save energy.
• Daily maintenance: Clean the filter screen weekly, clean the wet curtain and water tank monthly to prevent scale and oil sludge from breeding bacteria. Check the water pump and float valve quarterly.
• Winter mode: If only ventilation is needed, turn off the water pump and use it as an ordinary fresh air fan; if heating is needed, switch to hot water coil mode.

Special reminder: Hot pot restaurants have heavy cooking fumes, so it is recommended to install a cooking fume purifier before the air inlet of the water-cooled fresh air fan; otherwise, the wet curtain will quickly be clogged with grease. Using LCCFAIR‘s anti-oil units can reduce cleaning frequency to once per quarter.

IV. Practical Solutions for Hot Pot Restaurant Kitchen Cooling Planning

A typical hot pot restaurant kitchen (approximately 80-120㎡) can be planned according to the following steps:

• Heat source analysis: Count the number and power of stoves, soup pots, and steam cabinets to estimate total heat dissipation. Generally, each hot pot stove burner requires approximately 3,000-5,000 m³/h of air supply volume.
• Airflow organization: Adopt “down-supply and up-exhaust” or “side-supply and side-exhaust.” Workstation air supply ducts deliver cool air directly to the back or above the chef’s head, with exhaust outlets set above the stove to form directional airflow and prevent cooking fumes from spreading.
• Equipment selection: Select air-conditioning water-cooled fresh air units based on total air volume and cooling requirements. For example, for a 100㎡ kitchen, it is recommended to choose 2-3 LCCFAIR water-cooled fresh air fans with a total air volume of 15,000-20,000 m³/h.
• Zoned control: Divide the kitchen into a wok area, prep area, and dishwashing area, with independent air volume control. The wok area needs the maximum cooling capacity, while the dishwashing area needs dehumidification.
• Balance of supply and exhaust air: The fresh air fan supply volume should be 80%-90% of the exhaust volume, maintaining slight negative pressure to prevent cooking fumes from escaping.

In addition, it is recommended to reserve spare air outlets in the hot pot restaurant kitchen cooling planning to add mobile water-cooled fans during extreme summer heat. Regularly monitor kitchen temperature and humidity, with the goal of keeping the operating area temperature below 28°C and humidity below 70%.

V. How to Choose a Reliable Commercial Kitchen Air Conditioning and Water-Cooled Fresh Air Fan Manufacturer?

There are many brands of commercial kitchen air conditioning and water-cooled fresh air fans on the market, but few are specifically designed for catering kitchens. When choosing, pay attention to the following points:

• Grease resistance: Is it equipped with easily removable and washable filter screens and anti-oil wet curtains? Is the motor fully enclosed?
• Cooling efficiency: Check the wet curtain thickness and heat exchange area. High-quality units can achieve a temperature drop of 8-12°C.
• Energy efficiency and intelligence: Does it support variable frequency, automatic water replenishment, and fault alarms?
• Brand reputation: Refer to industry top ten brand lists. Manufacturers focused on the commercial kitchen field, such as LCCFAIR, typically provide free solution design and installation guidance.
• After-sales service: Kitchen equipment requires regular maintenance, and whether the manufacturer can provide rapid-response cleaning and repair services is crucial.

Remember: Low-priced units often use thin wet curtains and low-air-volume fans, and problems frequently arise within half a year. Investing in a reliable set of air-conditioning water-cooled fresh air units not only improves chef comfort but also reduces turnover rates and ensures food safety.
