Evaporative cooling air-conditioning technology, also known as "zero-cost refrigeration technology," "green air conditioning," and "bionic air conditioning," is a truly energy-saving, environmentally friendly, and sustainable refrigeration and air-conditioning technology. Its implementation in China plays an important role in reducing emissions. Among these, the "Research on Key Technologies for Indirect Evaporative Cooling" has been included as part of the major research project—"Research and Demonstration of Key Technologies for Building Energy Conservation"—under the National Science and Technology Support Program during the 11th Five-Year Plan period. For the northwest region of China, which covers more than half of the country's total area, the significant temperature differences between day and night and the dry air create unique climatic conditions that provide an ideal natural environment for the application of evaporative cooling technology.

To align with the broader societal push for low-carbon and energy-saving practices, Tianxing has developed the ZF series of intelligent evaporative-cooling central air-conditioning systems, which integrate energy efficiency, environmental protection, and health benefits. This unit uses natural water as its refrigerant, eliminating the need for a separate chiller unit to provide cooling—thus fundamentally preventing environmental pollution caused by refrigerant emissions into the atmosphere. The unit’s refrigerant circulates via tap water, supplemented periodically by automatic water refills. The water in the tank undergoes specialized treatment using dedicated equipment to soften and disinfect it, effectively addressing issues such as scaling, embrittlement, and bacterial growth in the evaporator—all of which can be triggered by poor water quality. Moreover, this unit features a fresh-air air-conditioning system that significantly improves indoor air quality and eliminates the threat posed by bacteria.

 

I. The best achievable range for key indicators:

The Tianxing ZF series evaporative cooling air conditioners come in two types: direct evaporative cooling and indirect evaporative cooling.

1. Airflow: Depending on user requirements, the typical airflow ranges from 1,000 m³/h to 160,000 m³/h; the maximum airflow can reach 1,500,000 m³/h.

2. Wind pressure: 500 Pa ~ 4000 Pa;

3. Leakage rate: <2%;

4. Adaptable to filtration methods for various industries. Purification level: Class 10 or higher;

5. Under the premise of standardized operation, the service life is over 20 years.

6. Noise: Below the national standard;

 

II. Main Features:

The design is rational, aesthetically pleasing and elegant, easy to maintain, with straight lines, compact size, high strength, and free of thermal bridges. The wall panels feature a modular design; each panel can be freely assembled or disassembled. High-pressure foam insulation in the wall panels ensures both excellent thermal performance and structural strength.

Composite Filtration: (Patented Technology)

The combination of a primary-efficiency plate-type filter and a medium-efficiency bag-type filter is referred to as a composite filter. The plate-type filter is meticulously crafted using imported high-polyester nylon fibers combined with a unique manufacturing process. This composite filter achieves a filtration efficiency of over 75%, placing it second only to high-efficiency filters. Second, the plate-type filter plays a crucial role in initial filtration, effectively reducing the workload on the medium-efficiency filter. As a result, the service life of the medium-efficiency filter can be extended by more than five times. Third, this plate-type filter employs a magnetically “self-suction” fixing mechanism, making it simple and convenient to install and remove. Fourth, the plate-type filter is easy to clean—simply rinse it with a high-pressure water jet or gently tap it with a stick. Fifth, it has a broad range of applicability and can withstand the erosion of various harmful substances. Sixth, it boasts excellent reusability, being washable more than 30 times.

▶ Several special structural features of the Tianxing evaporative cooling air-conditioning unit series:

- The patented enclosure structure ensures that the inner surface is completely smooth, with no cut edges or grooves.

- The optimized intake and exhaust chambers allow complete access to all functional sections and components;

- The unit can be thoroughly inspected from the outside through the inspection window and internal lighting.

- Select the appropriate material from stainless steels across all quality grades to provide exceptionally high corrosion protection.

- Optimize the fan section to reduce pressure loss, thereby lowering operating costs;
