The cooling principle of the air-cooled cooling fan is:

When the fan is operating, it creates a negative pressure inside the cavity, causing outdoor air to flow over the porous, moistened wet mat surface, forcing the air passing through to have a dry bulb temperature close to the outdoor air's wet bulb temperature. This means the dry bulb temperature at the air cooler's outlet is 5-12℃ lower than the outdoor dry bulb temperature (up to 15℃ in arid regions), with the greater the dry heat, the larger the temperature difference, and the better the cooling effect. Since air is constantly drawn from the outside to the inside (at this point referred to as a positive pressure system), it maintains the freshness of indoor air. Additionally, as this unit utilizes the evaporative cooling principle, it has both cooling and humidifying functions (relative humidity around 75%), which is suitable for use in textile and knitting workshops. It not only improves the cooling and heating conditions but also purifies the air, reduces the rate of needle breakage during the knitting process, and enhances the quality of the knitted products.

The cold air machine is surrounded by a honeycomb-like wet pad made of special materials, which has a large surface area and is continuously moistened through a water circulation system; inside the wet pad cold air machine, an efficient, low-noise, energy-saving fan is installed. When the fan operates, it creates a negative pressure in the wet pad cold air machine, causing external air to flow through the porous, moist wet pad into the machine. As the water on the wet pad evaporates, it absorbs heat, forcing the air passing through the wet pad to cool down. Simultaneously, due to the evaporation of water on the wet pad into the air passing through it, the humidity of the air is increased. Therefore, the wet pad cold air machine has the dual function of cooling and humidifying.

Key Features of Air-Cooled Refrigeration Units:

Low investment, high efficiency (only consumes 8/1 electricity compared to traditional central air conditioning).

②Using a cold air blower allows for the windows and doors to remain open.

③ Capable of replacing indoor polluted, stuffy, and smelly air with outdoor air.

④ Low power consumption, each unit consumes 1.1 kWh per hour, and does not use Freon.

⑤Airflow of each cold air blower: 6,000-80,000 cubic meters.

⑥ Each unit covers an area of 100-130 square meters with cold air.

⑦The main cooling component (wet curtain) uses imported parts.

Features of Air-Cooled Refrigeration Units:

1. Eco-friendly Product: This product is compressor-free, coal-free, and pollution-free, utilizing the principle of outdoor fresh air evaporation cooling to lower temperatures and achieve ventilation and cooling through convection with the indoor air.

2. Low operating costs and quick return on investment: Compared to traditional compressor air conditioning series, the power consumption is only 1/8 to 1/10.

3. Significant Cooling Effect: In areas with higher humidity (such as southern regions), it typically achieves a noticeable cooling effect of around 5-9°C; in particularly hot and dry regions (such as northern and northwestern areas), the cooling range can reach approximately 10-15°C.

4. Low investment cost, no floor space occupied: Compared to traditional compressor air conditioning systems, the cost is less than half, and the equipment occupies no floor space.

5. Maintain clean, hygienic indoor air: The evaporative cooler's distinctive feature is its open doors and windows for ventilation, ensuring a 100% fresh air exchange that keeps people in a natural environment at all times, completely free from the discomfort traditionally associated with air conditioning, and expelling polluted air outdoors.

6. Easy Maintenance and Installation: The system is straightforward, allowing for quick and easy installation and maintenance without the need for professional staff.

7. Prevent Air Drying: It can moisturize the skin and offer certain benefits to it.

8. Low noise, minimal vibration: Our air conditioner stands out among domestic counterparts for its low noise level, allowing you to enjoy a refreshing, natural breeze without even noticing. The unit itself does not dissipate heat to the surrounding area.
