The cooling principle of the air-cooled refrigerant cooler is:
When the fan is operating, it creates a negative pressure inside the cavity, causing outdoor air to flow over the porous and moist wet curtain surface, forcing the air passing through to have its dry bulb temperature reduced to nearly that of the outdoor air's wet bulb temperature. This means the dry bulb temperature at the cold air outlet is 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 always drawn from outside to inside (at this point referred to as a positive pressure system), it maintains the freshness of the indoor air. Additionally, due to the machine's use of the evaporation cooling principle, it has both cooling and humidifying functions (relative humidity can reach about 75%), making it suitable for use in textile and knitting workshops. Not only does it improve the cooling and heating conditions, but it also purifies the air, reduces the rate of needle breakage during the needlework process, and improves the quality of needlework products.
The cold air machine is surrounded by a honeycomb wet pad made of special materials, featuring a large surface area, which is continuously moistened through a water circulation system. Inside the wet pad cold air machine, an efficient, low-noise, energy-saving fan is installed. As the fan operates, the machine generates a negative pressure, drawing air from outside through the porous, moist wet pad into the machine. The evaporation of water on the wet pad absorbs heat, forcing the air passing through the 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 Fans:
Low investment, high efficiency (only consumes 8/1 electricity compared to traditional central air conditioning).
② Using a cold air blower allows you to keep doors and windows open.
③ Capable of replacing indoor stuffy, hot, and smelly air with outdoor air.
④ Low energy consumption, each unit consumes only 1.1 kWh per hour, and does not use Freon.
⑤ Airflow per cooling fan: 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 pad) uses imported parts.
Features of Air-Cooled Refrigeration Fan:
1. Eco-friendly Product: This is an environmentally friendly product without a compressor, refrigerant, or pollution. It utilizes the cooling principle of evaporation with fresh outdoor air, achieving temperature reduction and air exchange with the indoor air for ventilation and cooling purposes.
2. Low operating costs, quick return on investment: Compared to traditional compressor air conditioning series, the power consumption is only 1/8 to 1/10 of it.
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 occupation: 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 windows and doors for ventilation, ensuring a 100% fresh air exchange that keeps occupants in a natural environment at all times, completely free from the discomfort traditionally associated with air conditioning, and expelling polluted air outside.
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 Dryness: It moisturizes the skin and offers certain benefits.
8. Low noise and minimal vibration: Among similar products domestically, this air conditioner boasts low noise levels, allowing you to enjoy a refreshing, natural breeze without even noticing it; the unit itself does not dissipate heat to the surroundings.
