D Series Modular Air-cooled Scroll Chillers Owner's Manual

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, efficiency and more reasonable design and
can be widely used at newly built or retrofitted 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 fixed master unit
malfunctions.
Compact structure: The modular design enables the compact structure, reduced volume,
◆
light weight, easy handling and shipping and flexible 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 efficiency.
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.
