Hermetical scroll compressor of global well-known brand has been used in PCA unit, with advantages of high efficiency, low noise, slight vibration, high reliability as well as long life. The compressor consists of dual or multi systems. With adjustable power function, it can automatically adjust output cooling capacity to save energy.
- Evaporator and Condenser
Both evaporator and condenser are composed of high-efficient copper tube with aluminum fins. They are manufactured by processing equipment imported from USA, with high-efficient heat transfer technology developed by Shenling. The heat exchanger has advantages of compact structure, small size and weight, high heat exchange rate and etc. Evaporator fins are made of hydrophilic corrugated sheets, which effectively reduces water droplets in air flow and improve anticorrosion. Condenser adopts corrugated fins where dust is not easy stick on and this ensures its long service life.
- Fan and motor
High-pressure centrifugal blower and axial-flow condensing fan with high-efficient motor of global well-known brands have been adopted. The blower has advantages of low noise, high pressure, large air volume and high efficiency. It is equipped with frequency converter to change air volume and pressure to satisfy the needs of real situation, so that one boarding bridge can serve for different aircrafts. Axial-flow fan motor with protection IP54 is dust-proof and splash-proof. Thus, the blower operates safely and reliably.
- Use famous main refrigerating components with excellent performance
Main components, including expansion valve, dry-filter, solenoid valve, sight glass, high-low pressure protector and etc., are selected from global famous brands, which guarantee high performance and stable operation of the whole unit.
Anti-corrosion treatment enables the unit to work in airport outdoor environment.4、Intelligent Control System
