Product Introduction 

■ 

Overview

 

R410A-series modular  air-cooled  chiller  unit  is  designed  to  satisfy  users  with  the  maximum reliability, 
safety and adaptability. 

The  unit  is  well  designed  with  aesthetic  and  elegant  appearance.  Additionally,  with  adaptable 
configuration, the unit can be connected to various specifications and types of fan coils or air handling 
units. 

By  virtue  of  such  advantages  as  high  efficiency,  low  noise,  easy  and  safe  operation,  and  convenient 
installation  and  maintenance,  the  unit  is  widely  applied  in  factories,  stations,,  hotels,  villas,  office 
buildings, high-end residences, etc., and also used for industrial cooling. 

 

High efficiency and energy saving 

R410A-series modular air-cooled chiller unit adopts international advanced technology and is equipped 
with  accessories  of  world-known  brands  and  subject  to  full  test,  to  ensure  the  reasonable  matching. 
When running,The adoption of fully closed scroll compressor and low-noise fan makes the noise more 
lower;  efficient  scroll  compressor  and  precise  electronic  expansion  valve  throttling  system  ensure  the 
high EER and COP values, and improve the unit efficiency especially when partial loads are in operation 

R410A-series modular air-cooled chiller unit can be controlled in two steps, and the modules may be 
combined to enable the multi-step control; for example, 16-step control is achievable when the modules 
of  eight  sets  of  CA0070EAND  units  are  combined,  which  is  almost  as  effective  as  infinitely  variable 
control.  The  stepped  operation  of  electronic  control  unit  can  reduce  the  impact  on  power  grid  in  the 
startup and improve energy efficiency. 

 

Easy control 

An electronic controller is adopted for the unit, enabling the centralized control and independent control; 
the controller has high anti-interference capability and can control the unit from as far as 1000 meters; 
the  monitoring  of  unit  operation  is  convenient;  in  case  of  unit  fault,  the  controller  will  display 
corresponding fault codes. 

 

Convenient installation 

The unit is designed to maximize the ease of installation. The cooling system has been fabricated as a 
closed system in factory, so no copper tube connection and refrigerant charging is required. The water 
system has inlet and outlet joints reserved for the connection with end equipment; upon the completion 
of installation as required, the system can be energized and started up after the water filling, provided 
that the water and the water pump pipes are clean. 

The unit is reasonably structured and occupies a limited area; moreover, no specialized room is required 
for the installation, and the unit can be placed around a house or on balcony or roof. 

 

Safe operation 

The cooling system is provided with high/low pressure protection to avoid too high discharging pressure 
and too low suction pressure; the discharging temperature protection prevents the cooling system from 
too high dischargingt temperature; the anti-freezing protection of the cooling system prevents the frost 
crack  inside  the  plate  heat  exchanger  under  too  low  water  temperature;  besides,  the  anti-freezing 
protection  of  the  unit  avoids  the  frost  crack  of  the  plate  heat  exchanger  under  too  low  outdoor 
temperature when the unit stops in winter (the function is only available if the main power supply keeps 
on and the heating control is conducted). 

 

Convenient maintenance 

All  parts  are  accessible when  side  panel  or  front  panel  of  the  unit  is  removed,  so  it  is  convenient  for 
maintenance and repair. In case of trip under abnormal conditions,  the controller will display the fault 
cause to facilitate the rapid troubleshooting.
