Economizer Cycle

Liquid refrigerant passes through the first expansion device and into

the flash economizer where flash gas and liquid refrigerant are separated.

The gaseous refrigerant is then drawn out of the flash economizer and into

the vapor injection port of the compressor. The remaining liquid

refrigerant then passes through a second expansion device which reduces

refrigerant pressure to evaporator levels where it is then distributed evenly

into the evaporator.

By removing the flash gas from the flash economizer at an

intermediate pressure, the enthalpy of the refrigerant flowing into the

evaporator is reduced which increases the refrigeration effect and

improves the efficiency of the refrigeration cycle about 16%

Shell and Tube Flooded Coolers

Flooded Coolers operate considerably different than Direct Expan-

sion Coolers. They have the refrigerant in the shell side with the fluid to

be cooled in the tubes. The liquid level of refrigerant in the shell covers

the tubes with refrigerant. This direct contact enables the cooler to oper-

ate more efficiently than a direct expansion cooler by having a closer

total temperature difference (TTD). Flooded Coolers employ the most

advanced vessel technology available today. Special internal and extern-

al enhanced tubing provides excellent unit efficiency. These coolers are

designed and constructed to meet the requirements of the JB4750-2003.

and are stamped accordingly. The tubing is roll expanded into the tube

sheets and the heads are removable and interchangeable from end-to-end

for ease of tube maintenance. Vent and drain plugs are provided in each

head. Two-pass coolers are supplied standard with one and three-pass

optional.

Shell and Tube Condenser

The condenser is a cleanable "shell and tube" type with high efficiency

external and internal enhanced copper tubes, mechanically expanded into

heavy fixed steel tube sheets. The condenser is sized for full refrigerant

pump down capacity and the shell side is equipped with dual refrigerant

relief devices. Vent and drain fittings are provided in each head and the

heads are removable for tube cleaning and serviceability.

Compressor

The Dunham-Bush rotary screw compressor is a positive displace-

ment helical-axial design for use with high pressure refrigerants.

• The compressor consists of two intermeshing helical grooved rotors, a

drive rotor and a driven rotor, in a stationary housing with suction and

discharge gas ports.

• Uniform gas flow, even torque and positive displacement, all provided

by pure rotary motion contributes to vibration-free operation over a wide

range of operating conditions. Intake and discharge cycles overlap,effect-

ively producing a smooth, continuous flow of gas.

• No oil pump is required for lubrication or sealing purposes. Oil is dist-

ributed throughout the compressor by the pressure differential between

the suction and the discharge cavities.

Simplified Capacity Control

The slide valve mechanism for capacity modulation and part-load

operation is an outstanding feature.

• The moving parts are simple, rugged and trouble-free. The slide mech-

anism is hydraulically actuated.

• Package capacity reduction can be down to as low as 25% without

HGBP by progressive movement of slide valves away from their stops.

• Capacity reduction is programmed by an exclusive electronically initi-

ated, hydraulically actuated control arrangement.

Positive Displacement Direct Connected

The compressor is directly connected to the motor without any comp-

licated gear systems to speed up the compressor and thus detract from

the overall unit reliability.

Oil Separator

Each compressor is provided with an integral oil separator located

adjacent to the discharge gas port.

• The separator is a multi-layered mesh element which effectively sepa-

rates oil from the gas stream.

• The oil drains into the sump and the discharge gas passes around the

deflection plate. An oil drain valve is located near the bottom of the oil

sump.

Main Bearings

Each rotor is fitted with a set of anti-friction tapered roller bearings.

They carry both radial and thrust loads.

Rotors

The latest asymmetrical rotor profiles of patented Dunham-Bush

design assure operation at highest efficiencies. Rotors are precision

machined from AISI 1141 bar stock and case hardened.

Castings

All housings are manufactured of high grade, low porosity,cast iron.

Solid State Motor Protection. The motor winding protection module used

in conjunction with sensors embedded in the compressor motor windings

is designed to prevent the motor from operating at unsafe operating tem-

peratures. The overloads for the motor are also solid state.

Display Information

The alphanumeric liquid crystal display utilizes easy-to-understand

menu-driven software.Inexperienced operators can quickly work through

these menus to obtain the information they require or to modify control

parameters. More experienced operators can bypass the menu systems, if

desired, and move directly to their requested control function. Easily

accessible measurements include:

• Leaving chilled water temperature

• Evaporator pressure

• Condenser pressure

• System voltage

• Number of compressor starts

• Compressor contactor status

• Water temperature reset value

• Water flow switch status

• External start/stop command status

Advanced Microcomputer Control is a standard feature on all Dunham-

Bush Rotary Screw Water Cooled Chillers monitoring analog and digital

inputs to achieve precise control of the major operational and protective

functions of the unit.

Programmable Logic Controller (PLC) allows finger-tip user inter-

action. Its simple-to-use push button keyboard and menu-driven software

provide access to operating conditions, control setpoints and alarm hist-

ory clearly displayed on a prominent multi-line alphanumeric display.

An easy-to-install, inexpensive modem option allows remote reading of

operating parameter updates. The Dunham-Bush microcomputer insures

Capacity Control

Leaving chilled water temperature control is accomplished by enter-

ing the water temperature setpoint and placing the microcomputer in

automatic control. The unit will monitor all control functions and move

the slide valve to the required operating position. The compressor ramp

(loading) cycle is programmable and may be set for specific building

requirements. Remote adjustment of the leaving chilled water setpoint is

accomplished through either direct connection of other Dunham-Bush

control packages to the microcomputer through either the RS485 long

distance differential communication port, via terminal or modem connec-

ted to the RS232 communication port, or from an external building auto-

mation system supplying a simple 0 to 5 VDC signal. Optional remote

reset of compressor current limit may be accomplished in a similar fash-

ion.

System Control

The unit may be started or stopped manually or through the use of an

external signal from a Building Automation System.

System Protection

The following system controls will automatically act to insure system

protection:

• Low suction pressure

• High discharge pressure

• High motor temperature/overcurrent

• Freeze protection

• High motor temperature

• Low differential pressure

• Low oil level

• Compressor run error

• Power loss

• Chilled water flow loss

• Sensor error

• Compressor overcurrent

• Anti-recycle

The microcomputer will retain the latest thirty alarm conditions complete

with time of failure in an alarm history. This tool will aid service

technicians in trouble shooting tasks enabling downtime and nuisance

trip-outs to be minimized.

Remote Monitoring

The microcomputer is complete with an RS232 communications port

and all hardware and software necessary to be remotely monitored and

controlled from a simple terminal and optional phone modem. This valu-

able enhancement to the refrigeration system allows the ultimate in

serviceability. The microcomputer as standard is additionally equipped

with history files which may be used to take logs which may be retrieved

via the phone modem periodically. Now owners of multiple buildings

have a simple and inexpensive method of investigating potential

problems quickly and in a highly cost effective manner. Dunham-Bush

has open Protocol on its microcomputer to allow direct interface with

Building Management Systems.
