The cooling principle of the air-cooled refrigerant cooler is:
When the fan operates, it creates a negative pressure inside the chamber, causing outdoor air to flow over the porous, moist curtain surface, thereby lowering the dry bulb temperature of the air passing through to nearly match the outdoor air's wet bulb temperature. This results in the dry bulb temperature at the cold air outlet being 5-12℃ (up to 15℃ in arid regions) lower than the outdoor dry bulb temperature. The drier and hotter the air, the greater the temperature difference, and the better the cooling effect. Since air is constantly being drawn from outside to inside (at this point referred to as a positive pressure system), it maintains the freshness of indoor air. Additionally, due to the use of the evaporation cooling principle, the unit offers both cooling and humidifying functions (relative humidity around 75%), making it suitable for use in textile and knitting workshops. It not only improves cooling and heating conditions but also purifies the air, reduces the breakage rate of threads during needlework, and enhances the quality of needlework products.
The cold air machine is surrounded by a honeycomb-like wet pad made of special materials, which has a large surface area. It is continuously humidified through a water circulation system. Inside the wet pad cold air machine, there is an efficient, low-noise, energy-saving fan. When the fan operates, the machine generates a negative pressure, causing external air to flow through the porous and 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. At the same time, 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 (just 8/1 electricity consumption compared to traditional central air conditioning).
② Use a cold air blower to keep doors and windows open.
③ Capable of replacing indoor polluted,闷hot, and smelly air with outdoor air.
④Low power consumption, each unit consumes only 1.1 kWh per hour, free of Freon.
⑤Airflow of each cooling fan: 6,000—80,000 cubic meters.
⑥ Each unit covers up to 100-130 square meters of cold air.
⑦Cooling main component (wet curtain) utilizes 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 by means of convection with the indoor air.
2. Low operating costs and quick return on investment: Compared to traditional compressor air conditioning series, the electricity consumption is only 1/8 to 1/10.
3. Significant Cooling Effect: In areas with higher humidity (such as southern regions), a noticeable cooling effect of about 5-9°C is typically achieved; 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 does not occupy any 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 technicians.
7. Prevent Air Drying: It moisturizes the skin and offers certain benefits to it.
8. Low noise and minimal vibration: This air conditioner stands out with its low noise level among domestic counterparts, allowing you to enjoy a refreshing, natural breeze without even noticing; the unit itself does not dissipate heat to the surroundings.
