D Series Modular Air-cooled Scroll Chillers
5
1 General Introduction
Main technical data of D series modular air-cooled scroll chillers are listed on the nameplate.
D series modular air-cooled scroll chillers are developed based on the B series modular air-cooled
scroll chillers. However, it has higher reliability, eciency and more reasonable design and can be widely
used at newly built or retrotted industrial and civil buildings in various sizes, such as, hotels, apartments,
restaurants, office buildings, shopping malls, theaters, gyms, workshops, hospitals and other places
where there are high requirements on noise level and air but the cooling tower is going to be installed
troublesomely.
The applicable refrigerant for D series modular air-cooled scroll chillers is R22 or R410A.
D series modular air-cooled chillers work outstandingly by virtue of their major features stated below.
◆
Excellent compatibility:
Each D series modular air-cooled scroll chillers is constructed of up to 16 single units of 65D, 80D or up
to 8 single units of 130D,160D which may vary in structure and in capacity.
◆
Free master module design:
Any single unit can operate as the master once connected with the wired controller. It overcomes the
problem which would occur to the product of other manufacturer that the whole system would fail to work
properly when the xed master unit malfunctions.
◆
Compact structure:
The modular design enables the compact structure, reduced volume, light weight, easy handling and
shipping and exible installation.
◆
Powerful self-protection:
It is equipped with the top-end microcomputer control system which is capable of providing well-rounded
protection and self-diagnosis.
◆
High reliability:
It is constructed of well-designed refrigeration parts for multiple refrigeration cycles, adequately
guaranteeing the reliable operation.
◆
Hermetic scroll compressor:
Compared with other type of compressor under the same cooling load, it has few movable components,
smaller rotating torque, lower noise and vibration and higher reliability and eciency.
◆
Equilibrium running:
It indicates each compressor will run alternately so as to extend their service life.
◆
Humanized operation designing:
When the unit runs out of the allowable temperature range, an alert will rise on the display.
◆
Low maintenance cost:
The especially design structure allows easy access and service and low maintenance cost.
◆
Hi-precision electronic expansion valve:
The hi-precision electronic expansion valve is used as the throttling device, providing high reliable,
sensitive and precise service.
