Unit Function Section

The combined air conditioning unit of the clean operating room can be designed with different air treatment functional sections: fresh return air mixing section, primary filter section, surface cold dehumidification section, heating section, humidification section, secondary return air mixing section, fan section, and current equalization section , Medium-efficiency filter section, sub-high-efficiency filter section, sterilization section, air supply section, host side, etc., through the unit function section to perform one or more treatments on the air to meet the required technical requirements for working conditions and effects

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.

Application

• Clean rooms and controlled environments

• Healthcare, pharmaceuticals, electronics, and precision machinery

• Laboratories, research centers, and hospitals

• Light and chemical industries

• Large public buildings with precise air purification and temperature/humidity control

The effect of lengthening the connecting pipe of the indoor unit on the cooling capacity (recommended the longest pipe length is 35m)

 
Table of equivalent lengths of elbows and traps

Note: the equivalent pipe length refers to the sum of the length of the straight pipe section of the pipeline plus the equivalent length of the elbow and the trap

Note:
1. The power cord of the unit must be a copper core cable, and the working temperature cannot be greater than its specified value. The recommended wire diameter is to use Google when the operating environment is 40 degrees Celsius.
2. If the length of the power cord is greater than 15 meters, please increase the cross section of the power cord appropriately to avoid accidents caused by overload;
3. The recommended power cord diameter does not consider the auxiliary heater. If the unit is equipped with an auxiliary electric heater, it is necessary to select a copper core cable with a wiring diameter that meets the national standard according to the auxiliary electric heater power to avoid accidents. At the same time, when the actual installation conditions on site are changed, please reduce the capacity according to the specifications of the power cord and circuit breaker provided by the manufacturer.
