A. Controller.

◎ Touchscreen PLC controller, easy to operate and manage

The working status of all systems is displayed in text and graphic form on the control panel, which is clear at a glance and easy to understand

The controller can operate independently or form an integrated centralized management online

The controller can be built on the surface of the air conditioning unit or set up nearby indoors to monitor the unit on site.

B. Compressor.

Copeland Valley Wheel's efficient and reliable fully enclosed eddy current refrigeration compressor from the United States

◎ It has the advantages of high volumetric efficiency (more than 10% higher than traditional piston compressors), fewer moving parts, low vibration, low noise, and strong hydraulic resistance

Efficiency: According to ARI standards, the coefficient of performance (COP) exceeds 3.35W/W

◎ Low noise: The new design eliminates vibration of the intake and exhaust valves, significantly reducing noise

Safe and reliable: operates continuously, tolerates liquid reflux, and has an extremely low failure rate.

C. Humidifier.

◎ Italian Carl efficient humidification system

Fuzzy control technology: Control the humidification amount through humidification current and automatically monitor the water conductivity

◎ AFS control technology: mesh humidification electrode, large contact surface, foam prevention, automatic drainage, automatic cleaning

◎ Convenient maintenance technology: detachable humidifying body, tank made of fireproof material, reusable

The immersion electrode humidification system can automatically and accurately control various functions through a microprocessor, and automatically adapt to the water quality in different regions.

ventilator.

Efficient and low-noise centrifugal fans, available in various forms such as forward multi wing, backward circular arc, and backward wing

Select computer software based on air volume, air pressure, noise, and power, and correctly combine high-quality motors

◎ Use a fan with drive or a direct drive fan

◎ Design for low RPM and high torque

Minimize operating noise to the greatest extent possible

◎ It has a minimum lifespan of 100000 hours of operation.

D. Filter.

The filtering material should not contribute to the growth of microorganisms

◎ Only fully sealed gaskets can be used

Even in humid environments, the mechanical properties of materials must be sufficiently stable

◎ Filter differential pressure control is equipped with visual inspection or electronic control as standard configuration.

E. Evaporator.

The direct expansion refrigeration coil adopts high-purity seamless copper pipes and aluminum interference plates, which are tightly combined with the copper pipes and aluminum plates through mechanical expansion pipes to achieve the best heat transfer effect

The dual advantages of dual sine wave honeycomb fins and window fins ensure high heat exchange coefficient while having low air resistance

Honeycomb fins enhance airflow interference through intermittent concave convex stretching processing structures. The fins have smaller cut cross-sections, reducing the accumulation and retention of dust in the air on the fins

After long-term operation, the refrigeration coil still has high heat transfer efficiency.

F. The structure of the box.

◎ Patent box structure, making the inner surface completely smooth, without cutting edges or grooves

The box is not prone to condensation (the insulation performance of the box reaches the European EN1886-1997T2/TB2 level)

◎ Low air leakage rate (the air leakage rate of the box meets the A-level requirement of EN1886-1997 standard, which is equivalent to a clean air conditioning air leakage rate of less than 1% according to GB/T14294-93 standard)

◎ High quality galvanized steel plate, stainless steel plate and cold formed steel are used, with strong aging resistance

To avoid surface corrosion of the panel, galvanized panels with unprotected cutting edges are not used

The door and panel seals are made of high-density, non aging materials

All parts should be easy to inspect, equipped with necessary lighting equipment, inspection doors, and observation windows.
