Chapter I Product Selection
1．General
1.1 Product Overview
Flooded-type water-cooled screw chiller unit has characteristics such as high efficiency ratio, compact
structure, beautiful shape, convenient operation and simple cooling system. The unit can be put into
operation immediately after simple installation, water and electricity connection, with improved
operating reliability, safety and economical efficiency of system.
Applicable places:
It is applicable to shopping mall, hospital, hotel, factory, office building, etc.
Product Characteristics:
Flooded-type dedicated compressor:
Adopted semi-hermetic twin-screw compressor and 5:6 unsymmetrical serrated structure which
realize high compression efficiency, 10% energy saving and stable operation;
Since oil level switch is above oil level, it is easy to maintain and repair;
Air suction filter has characteristics of high precision (25μm), large area and less pressure drop,
ensuring best filtering effect;
Oil filter has characteristics of high precision (10μm), large area and less pressure drop, which can
be used and set with maintenance and replacement;
Dual-layer casting wall structure effectively reduces operation noise;
Depressurized bearing housing design reduces content of refrigerant in lubricating oil entering into
bearing and can greatly prolong service life of bearing;
Screw of compressor has compact structure and low length/diameter ratio, which is hard to deform
and more efficient;
Flooded-type shell and tube heat exchanger:
Tailor-made refrigerant distributor makes temperature field of heat exchanger distribute more
evenly. Its total heat transfer coefficient is more than three times of traditional dry evaporator, so it
can transfer heat at low temperature difference, effectively improve cooling capacity and
energy/efficiency ratio of unit and save operating cost;
Chilled water flows in pipe at turbulent flow and is difficult to scale. Removable end plate is easy to
clean and service;
Wide range of cooling capacity:
Wide range of cooling capacity, which can meet different places’ requirement.
Two types: common energy efficiency and high energy efficiency can meet different demands of
users.
More reliable oil-return system:
It uses high-efficiency technology for separating oil two times to minimize oil displacement of
compressor.

Flooded Type Water Cooled Screw Chiller Technical Manual

It uses high-pressure injection oil return technology to ensure reliable oil-return in all working
conditions.
Accurate matching and higher energy efficiency:
Compressor provides stepless energy adjustment, which can accurately match with actual working
condition and save more energy;
Twin-compressor has parallel connection design and high seasonal energy efficiency;
Intelligent control system:
Visual Operation Control. The set information such as operating status, setting parameter and
failure alarm can reflect to controller and make easier operation and more comprehensible;
Balance control function. Unit automatically adjusts operation time of each system according to
operation status of compressor, which ensures roughly the same operation time of each system,
achieves balanced operation among multiple systems and ensures overall operation stability of
unit.
Unit can select manually or automatically ON/OFF at specified time which bring great convenience
to users. Unit can completely record the last twenty alarm records and occurrence time, providing
detailed information for after-sales maintenance;
It has complete protection function including over high pressure protection, less low pressure
protection, overload protection of compressor, superheat protection of coil, phase lost and reversal
protection, high/low voltage protection, oil level protection, high discharge temperature protection
of compressor, oil pressure difference protection of compressor, chilled water and cooling water
flow protection, overload protection of cooling tower fan and protection function for external linkage.
Multiple protection functions ensure reliable protection of unit at the first time in case of
abnormality and ensure safety of unit;
Optional remote network control function. It can be connected with communication interface of
computer or modulator through RS-485 protocol and easily connected to BAS of standard
industrial bus and public telecom switch network to monitor remote communication;
