Condenser section

-  Vertical condenser coils

-  Protection grilles on anti-vibration mountings to protect the heat exchanger against possible shocks.

-  Low-noise latest-generation Flying Bird IV fans (Carrier patent) , made of a composite material are now even quieter and do not generate intrusive low-frequency noise

-  Rigid fan installation for reduced start-up noise (Carrier patent)

Economical operation

Increased energy efficiency at part load

-  The refrigerant circuit includes several compressors connected in parallel. At part load, around 99% of the operating time, only the compressors that are absolutely necessary operate. At these conditions the compressors operating are more energy efficient, as they use the total condenser and evaporator capacity.

-  The electronic expansion device (EXV) allows operation at a lower condensing pressure (EER, COP and ESEER optimization).

-  Dynamic superheat management for better utilization of the evaporator heat exchange surface.

-  Defrost cycle optimization (30RQ)

-  Very efficient

- gives an increased energy efficiency ratio

Leak-tight refrigerant circuit

-  Brazed refrigerant connections for increased leaktightness

-  Reduction of leaks due to reduced vibration levels and elimination of capillary tubes (TXVs)

-  Verification of pressure transducers and temperature sensors without transferring refrigerant charge

 
  1. 無洩漏製冷回路設計:所有制冷管路及部件均採用焊接聯接,選用電子式
  2. 溫度計和電子式壓力感測器,從根本上消除各種潛在洩露可能。

Superior reliability

 State-of-the-art concept

-  Cooperation with specialist laboratories and use of limit simulation tools (finite element calculations) for the design of the critical components, e.g. motor supports, suction/discharge piping etc.

 

Exceptional endurance tests

-  Corrosion resistance tests in salt mist in the laboratory

-  Accelerated ageing test on components that are submitted to continuous operation: compressor piping, fan supports

-  Transport simulation test in the laboratory on a

vibrating table.

  2. 確保了冷水機組極高的可靠性。
 

Pro-Dialog Plus Control

Pro-Dialog Plus combines intelligence with operating simplicity. The control constantly monitors all machine parameters and precisely manages the operation of compressors, expansion devices, fans and of the evaporator water pump for optimum energy efficiency.

 

User-friendly interface

-  The new backlighted LCD interface includes a manual control potentiometer to ensure legibility under any lighting conditions. The information is in clear text and can be displayed in English.

-  Unit uses intuitive tree-structure menus, similar to the Internet navigators. They are user-friendly and permit quick access to the principal operating parameters: number of compressors operating, suction/discharge pressure, compressor operating hours, set point, air temperature, entering/leaving water temperature.

 

 
                                                                                                                                                                                                                                                                                  

Advanced control function

-  Unit provides different control mode including LOCAL/REMOTE/CCN.

-  Remote control function including: Unit ON/OFF, dual set point control, demand limit control, user safety interlock, water pump control, operation indication, circuit alarm and alert etc.

-  Enable automatic reset of leaving water temperature according to return water temperature or outside air temperature to ensure optimum energy efficiency.

-  Control algorithm prevents excessive compressor cycling and permits reduction of the water quantity in the hydronic circuit (Carrier patent).

-  Automatic compressor unloading in case of abnormally high condensing pressure. If an abnomal incident occurs (e.g. fouled condenser coil, fan failure), Aquasnap continues to operate, but at reduced capacity.

控制功能先進

1. 30RB/RQ017~033提供室內機聯鎖控制與室內機通信控制兩種操作控制方式。
