Working principle and scope of application
Also known as energy‑saving environmental‑friendly air conditioner, air cooler, cooling machine, evaporative air conditioner, power‑saving air conditioner, water‑cooled air conditioner and energy‑efficient air conditioner, is an energy‑saving product advocated by the state. It is an evaporative cooling‑ventilation unit integrating cooling, air exchange, dust prevention and odor removal.
Besides delivering fresh air and lowering temperatures for factory workshops, public venues and commercial entertainment sites, the evaporative air cooler features outstanding energy efficiency and environmental protection.
This innovative eco‑friendly product has no compressor, no refrigerant and no copper tubes. Its core components consist of evaporative cooling pads (multi‑layer corrugated fiber composite) and a 1.1 kW main motor. It consumes only 1/8 of the power of conventional central air‑conditioning systems, delivering substantial electricity savings for various industries.
Application Scope of Evaporative Air Coolers
1.Venues with dense crowds or short‑term usage requiring rapid cooling Such as auditoriums, meeting rooms, churches, schools, canteens, gymnasiums, exhibition halls, shoe‑making factories, garment factories, toy factories, food markets, etc.
2.Sites with heavy polluting fumes, strong odors and large dust volume Such as hospital lobbies, waiting rooms, kitchens, chemical plants, plastic factories, electronics factories, chemical fiber factories, leather factories, rubber factories, textile mills, printing‑dyeing plants, spraying & screen‑printing workshops, breeding farms, etc.
3.High‑temperature production sites with heat‑generating equipment Such as workshops for mechanical processing, injection molding, electroplating, metallurgy, printing, food processing, glass production and home‑appliance manufacturing. It is also suitable for open‑access malls, supermarkets, amusement parks, entertainment venues, waiting rooms, as well as agricultural research & cultivation centers and bases.With the overall improvement of people’s living standards, public awareness of health keeps rising, and higher requirements are placed on working environments. Employees expect not only satisfactory salaries and benefits, but also a healthy and comfortable workplace. Furthermore, environmental protection and health preservation have become global key concerns.
4.The development of water‑cooled evaporative air coolers for household use has become a growing trend, which will surely make great contributions to household air‑conditioning energy conservation.
Cooling principle and energy saving characteristics
Principle of Evaporative Cooling and Ventilation Units: Based on the natural physical phenomenon that “water absorbs heat during evaporation, and the evaporation area affects evaporation efficiency,” air is passed through an evaporative cooling pad—whose effective heat exchange area is many times greater than its surface area—to absorb a large amount of heat, thereby achieving the cooling effect.
Characteristics of the Multi-Layer Corrugated Fiber Composite Cooling Pad:
The core component is the direct-evaporation cooling pad. The “multi-layer corrugated fiber composite” cooling pad is a Swedish patented invention. It consists of a special “multi-layer corrugated fiber composite” characterized by excellent water absorption and ventilation properties, a sturdy texture that resists deformation even when soaked in water, and corrosion resistance, with a normal service life exceeding 5 years.
Method for Calculating the Number of Units:
Definition of Air Change Rate: Air change rate (times/hour) = Total indoor supply airflow (m?/h) ÷ (Indoor area (m?) × Indoor height (m)). The number of units required = Site volume × Air change rate. Localized supply airflow should be selected separately based on actual conditions, and the total airflow rate may be appropriately reduced.
Energy-Saving Features of Eco-Friendly Air Conditioners:
1. Low initial investment and low operating costs; a single unit can effectively cool an area of 100–130 m² while consuming only 1.1 kWh of electricity per hour;
2. Compared to electric fans and exhaust fans under the same usage conditions in the same space, power consumption is reduced by 40%;
3. Compared to traditional compressor-based air conditioners under the same usage conditions in the same space, power consumption is reduced by 85%;
4. The product features mature technology, stable operational performance, and extremely low maintenance costs;
5. It creates a comfortable indoor climate in the work area, lowering the temperature by 4–10°C below the outdoor temperature in southern climates; in northern dry climates, it can lower the temperature by 8–15°C below the outdoor temperature, and reduce the indoor temperature in high-temperature factory workshops by 10–20°C;
6. It continuously delivers low-temperature, fresh, clean, oxygen-rich, and intensely cool airflow to the target area;
7. It prevents health hazards caused by environmental pollutants such as dust, high temperatures, and odors, ensuring that personnel in the work area breathe ample freshair, remain energetic, maintain sufficient physical stamina, eliminate irritability, and improve production efficiency while ensuring consistent product quality.
