Product Introduction
1.1 Unit characteristics
■
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.
