Features

1. High-strength structure: adopts high-strength cooling bridge aluminum alloy profile frame, beautiful appearance and high strength;
2. No deformation: The inner and outer panels and the insulation layer are foamed at one time, and the foaming density is not less than 48kg/m3, which can ensure that the unit does not deform under the pressure difference between the inside and outside of 2500Pa;
3. Anti-cold bridge: high-strength anti-cold bridge aluminum alloy structure, PA66 heat insulation material, completely solve the frame condensation problem;
4. Low air leakage rate: regardless of positive pressure or negative pressure, the air leakage rate is less than 1% under the pressure difference of 1000 Pa between the inside and outside of the machine;
5. Personalized design: improve non-standard customized designs such as annual refrigeration, low-temperature heating, low-temperature air supply, and compressor frequency conversion, and tailor-made technical solutions for clean projects.

Mixed section
The air mixing section is used to mix air in different states, and to control and adjust the flow of air. Generally, it is equipped with a return air inlet and a fresh air outlet, and is equipped with a manual or electric air volume control valve.

Primary-efficiency filter section
The primary filter section is used at the front end of the entire unit to intercept large particles such as dust and hair in the air, which can prolong the service life of the secondary filter. According to different wind speed, material, grade, thickness and technology, the initial resistance of the initial filter section is 150Pa, and the final resistance is about 120Pa.

Medium-efficiency filter section
The medium-efficiency filter section is used at the back end of the primary filter section to intercept large particles such as dust and hair in the air, which can prolong the use of the post-filter. According to different wind speed, material, grade, thickness and process, the initial resistance of the initial filter section is 15-50Pa, and the final resistance is 120Pa.

Sub-high-efficiency/high-efficiency filter section
The sub-high-efficiency filter section is used at the back end of the medium-efficiency filter section, intercepting dust and impurities with a particle size of 0.5μm in the air, with a moderate collection efficiency, which can extend the service life of the subsequent filter.
According to the wind speed, material, grade, thickness and process of the medium-efficiency filter section, its return force is 30-60Pa, and the final resistance is about 150Pa.
The filtration efficiency of the high-efficiency filter section can reach 99%, and its final resistance is about 300Pa. It is mostly used in high-grade clean rooms, operating rooms and other places with high cleanliness requirements.

Surface cold dehumidification section
The surface cold dehumidification section is used to cool and dehumidify the air, and play a role in regulating the environment and environmental humidity. Generally divided into chilled water type and refrigerant direct expansion type.

Heating section
It is generally placed after the surface cooling section to adjust the ambient temperature. It is generally divided into three types: hot water type, steam type and electric heating type.

Humidification section
It is generally placed after the heating section to adjust the temperature of the environment, and is generally divided into dry steam type, electrode type, high pressure micro mist type, ultrasonic wave and wet curtain.

Fan section
It is used to make the air in the local environment pass through the combined air conditioning unit and circulate, and do corresponding treatment according to requirements.

Sterilization section
It uses air or oxygen as raw materials to generate ozone by high-frequency and high-voltage discharge. It is recognized as a broad-spectrum and highly effective bactericide in the world. Ozone has one more active oxygen atom than oxygen molecule. It has a very active chemical property and is a strong oxidant. It can quickly kill bacteria in the air at a certain concentration, without any toxic residue, and will not form secondary pollution. 

The functions of the combined air conditioning unit of the clean operating room are flexibly combined according to the working conditions and technical design requirements, and can meet the needs of air purification and temperature and humidity adjustment systems in all walks of life. This product is widely used in medical treatment, medicine, electronic instruments, precision machinery, and products. The air-conditioning purification projects of enterprises such as, light industry and chemical industry are also suitable for the comfortable centralized air-conditioning projects of large and medium-sized public buildings such as scientific research buildings, hospitals, laboratories, training rooms, exhibition halls, shopping malls, and theaters.
