The 19 Series: Built to save energy, save you money and get the job done right

Dr. Willis Carrier invented centrifugal refrigeration in 1922 and today, more than half a century and 25,000 machines later. Carrier hermetic centrifugal liquid chillers still lead

the way in comfort air conditioning and process cooling. What’s more, the modern day 19 Series centrifugals are specifically designed to afford significant dollar savings on

utility bills, in every way possible.

The Carrier 19 Series centrifugal design philosophy has

always been to offer a variable line which meets each unique

specification while at the same time maintaining low first costs and low operating costs. Incorporated in this philosophy are such features as the 19 Series inline impeller design, hermetically sealed compressor-motors, gear drives and refrigerant options. The success of this concept can be seen in the 25,000 plus machines which have been applied to date.

Carrier’s hermetic centrifugals have always used various refrigerants at different tonnage ranges in order to keep the heat exchanger size and cost down. Now, over and above the low first cost concept, Carrier offers refrigerant options to meet your specific job requirements in the most efficient way possible.

Tbe full hermetic line consists of four models, each with

a cycle, refrigerant and tonnage range specifically matched to your application demands. From 100 tons (352 kW) to

2,000 tons (7034 kW), the Carrier hermetic centrifugals are

capable of performance at levels of .85 KW/Ton (3.0 KW/ kW) to .65 KW/Ton (2.3 KW/kW) and lower, depending on

design conditions. With features such as mix-match capa

bility, high performance heat exchangers, refrigerant options, multi-pass water boxes as well as tbe 19 Series her metic compressor designs, a Carrier centrifugal can be opti mized to meet any job requirement. The “Low Energy Con sumption Curve” illustrates performance levels possible

within the tonnage capabilities of the 19 Series hermetic line.

You get the most efficient, most reliable, energy-conscious and completely packaged machine for your particular appli cation. The hi-lift capabilities (up to 100 F) make the 19 line ideally suited for brine chilling, ice rink applications and process cooling. In areas with cooling tower restric tions, you can even specify a hi-lift Carrier centrifugal for use with closed circuit water condensing systems. The versatile Carrier centrifugals are also designed for low-lift requirements of today’s energy-conscious market.

Not only can Carrier Sales Engineers optimize your refrigeration requirements but they can optimize your total system as well. Thru various specialized computer pro grams, for example, a Carrier Sales Engineer can vary your leaving chilled water temperature a degree or increase your chilled water temperature differential from 10 to 14 F and show how the total system is affected with respect to operating costs. In this complex market of low energy con sumption as well as low first cost, Carrier can offer you productive ways to reduce your costs.

REFRIGERANT LIQUID/VAPOR

•SOCO)

^7000) kW

Carrier centrifugals use refrigerant (R-11, 114, 12 or 500) in a standard compression, single- or two-stage refrigeration cycle. System water in the cooler is chilled as its heat is transferred to refrigerant at low tem perature and pressure. As heat is re moved from the water, the refrig erant vaporizes and is drawn into the compressor at a rate controlled by the degree of the guide vane opening. As the compressor raises the vapor pressure, the saturation temperature of the refrigerant rises above that of

the condenser water. Refrigerant vapor is discharged directly into the condenser, where relatively cool condenser water removes heat from the vapor, causing it to condense again to liquid. The heated water leaves the system, returning to a cooling tower or other heat rejection device. The liquefied refrigerant then leaves the condenser, draining into

a chamber where a variable metering device regulates refrigerant flow and maintains a liquid seal to prevept vapor from passing into the cooler. As the refrigerant liquid goes thru this metering device, part of it vapor izes because of reduced pressure, cooling the remaining liquid to the

temperature at which the cycle began.

Energy-saving, precision design: extends compressor motor life, saves on operating costs, increases electrical efficiency

Hermetic design

Hermetic compressor design keeps motor free of airborne dirf and mois ture. It also isolates motor to keep heat and sound from equipment room. Eliminates shaft seal with its potential refrigerant leakage.

■ Gear driven compressors

Gear driven compressors allow more flexibility in selection than direct drive because gear ratios can be fitted to

19CB

particular application. Gear driven compressors also allow optimum im peller speed, higher head applications and increased operating efficiency.

Multi-pass water boxes

The complete 19 Series line offers 1,2,3

and 4 pass water boxes on both the

coolers and condensers. The result is

better heat transfer when needed —

reducing operafing costs. In addition,

all pass arrangements are available at

no extra cost.

Refrigerant-cooled motor

All 19 Series compressors have

refrigerant-cooled motors that operate at low, even temperatures throughout the motor windings to insure long motor life at high electrical efficiency.

19DH

Solid state capacity control

The capacity control module offers solid state compactness and reliability, with smooth and precise capacity mod ulation from 100% to 10% of full load, without hot gas bypass. It is more efficient in maintaining leaving water temperatures than any other type of control. The convenient, centrally located control center provides fully automatic machine operation, com plete with a full complement of safety interlocks. Check operating status at a glance, easily monitor all system oper ating points. The highly sensitive, factory-installed thermistor probe, solid state amplifier, and guide vane actuator are precisely matched and fully re sponsive to changes in leaving chilled water temperature. They help to main tain your selected design temperature throughout all operating load condi tions. The result is efficient, trouble-free operation with longer life expectancy.

All control connections can be made quickly to a single terminal strip; and once the solid state control has been

19EB

19FA

calibrated, control settings may be changed without additional field calibration.

55 F (13 C) condenser water

The Carrier metered refrigerant design allows the 19 Series chillers to operate efficiently with condenser water tem perature as low as 55 F (13 C) without

condenser water bypass or mixing

tanks. The 55 F (13 C) condenser water

means reduced head pressures which in turn means lower horsepower require ments The end result is lower energy

costs and lower annual operating costs. In addition, the absence of a condenser water bypass and mixing tanks add up to lower first costs and lower installation costs.

LZZZ

Compressor-motor-

heat exchanger mix-match

Each model within the 19 Series line

has the capability of mix-matching various heat exchanger sizes with an array of compressor-motor combina

tions. As illustrated, mix-matching

allows you to mount a small capacity

compressor on a large heat exchanger.

This design concept optimizes specified conditions, improving full and part load performance.

19DH

In-line impeller design

In-line impeller design, with diaphragm between stages, allows for more flexi bility in compressor component selec tion, which results in first cost savings on other machine components. Also provides higher head capabilities, pre vents uneven loading and allows for routine, easy maintenance.

Flash and thermal economizer

Two-stage models thru 1,600 ton (5627 kW) capacity feature a thermal economizer. The thermal economizer shown brings warm condensed refriger ant into contact with the inlet (coldest) water tubes where water as low as 55 F

(13 C) may be flowing. This low tem perature water subcools the refrigerant so when it moves on in the cycle it has greater cooling potential, thus im proving cycle efficiency and reducing power/ton requirements. In addition, all two-stage models employ a flash econo mizer, not shown, to further improve cycle efficiency. The liquefied refrig

erant leaves the condenser thru a

metering device and flows into the flash

economizer where the normal flashing

of part of the refrigerant into vapor is

used to cool the remaining refrigerant.

The flash vapor is diverted directly to

Thermal purge

The thermal purge effectively removes air, water, and noncondensables from the refrigerant system, promoting greater operating efficiency and lower maintenance costs. It needs no water connections or air-cooled condenser. It performs normal system purging during periods of operation on R-11 and R-114 machines. In addition, on R-11 machines it doubles as a pump for leak testing or machine evacuation after servicing. It also provides recovery of refrigerant under normal purging conditions.

Engineering excellence provides lower first costs and years of trouble-free service

Single unit construction

Carrier centrifugals are the most com pletely packaged units of their kind. Chiller is shipped as a single unit com plete with integral storage tanks where required. Ready for quick connection

to water and electrical sources at the job site. (Compressor is field installed on the 1,600-2,000 ton (5627-7034 kW)

models; the heat exchanger and

economizer are factory assembled.) In

addition. Carrier centrifugals arrive at

the job site with controls mounted and

pre-wired including the chilled water

thermistor. All control connections can

be made to a single terminal strip. Single

unit construction assures minimum in

stallation time, minimum installation

costs.

Factory-wired oil pump starter

Models available for U.L. listing feature

a factory-wired oil pump starter The

starter is factory wired to the machine

with overloads and contactors sized by

Carrier for U.L. compliance. The entire

assembly is factory mounted to save in

stallation time and field labor costs.

Permanent shipping bases

Rigging can be done faster and the need

for costly concrete bases and supports

is eliminated with 19 Series permanent shipping bases.

Prepiped motor lubrication package

The oil pump, motor, filter, cooler, pressure controls, and electrical ter minals are all prepiped and wired to save on-site labor costs and installation headaches.

Storage tank

The storage tank is an integral part of the machine design on all R-12 and R-500 units. No additional pipings, fittings or valves are needed. No in creased floor space is required which saves you first cost dollars. Servicing or testing may be easily accomplished without time-consuming transfer to separate containers which saves you service dollars. Models using R-114 offer the storage tank as an option at minimal cost. They are constructed to ASME code requirements and include all necessary connections for refrig erant transfer system.

Factory start-up

Carrier start-up service for your ma chine is included in the purchase price. This assures you of trouble-free, work ing installation right from the start. It

includes refrigerant transfer, leak test

ing and precision calibrating of the solid state control settings and safety control settings.

Integral chilled-water sensor

A chilled-water thermistor probe is fur nished, installed in the leaving chilled water nozzle as part of the machine’s standard control system. A signal from the sensitive solid-state device to the central control module automatically initiates immediate adjustments to com pressor capacity. This eliminates the need for accessory pneumatic equip ment, separate sensing devices, saves you initial equipment cost, and makes installation easier, more economical. As part of the machine’s standard control system, it does not have to be specified in another portion of the job, and thus further reduces first and installation costs.

Elapsed-time indicator

Every Carrier centrifugal features an

elapsed-time indicator to provide an

immediate and constant record of

machine operating hours. No over- or

underestimating when scheduling

maintenance. Mounted outside of the

control box for easy visibility.

Full line centrifugal service centers assure optimal care of your unit.

When you specify Carrier, you get a complete service organization unequaled in the industry. Carrier Service

j Operations is a national organization in over 150 key loca

tions throughout the United States and Canada. This is the one service organization that has grown up with the air conditioning industry. Today, more and more owners rely on Carrier Service Operations for an in-depth, practical

approach to energy conservation. This extraordinary full time commitment to quality maintenance and service proves Carrier’s interest in continued customer satis faction. Your centrifugal, in fact your entire HVAC system, will be in the care of people who are fully versed on the design, manufacture, installation, start-up and maintenance of your equipment.

Computer selection means “custom built” machinery — saves design time and lowers cost.

Supplementing the selections in this publication, Carrier has, for your convenience, developed computer selection and performance programs for 19 Series hermetic units that incorporate 800,000 combinations of condenser, compressor, and cooler components.

Convenience options offered for added energy-efficient, ‘tailor-made’ systems

Pneumatic capacity control

Complete pneumatic control systems are available, if desired, for the centri fugals in the 100 to 2000 ton (3527034 kW) sizes.

Safety indicator panel

This accessory provides the operator with an instant trouble-shooting capa bility. Seven panel lights monitor high motor or bearing temperature, low

refrigerant temperature, high con denser pressure, starter (overloads and protective devices), low water flow

(chilled or condenser), low oil pressure, low chilled water temperature. When safety is tripped, the light goes on. Panel does not affect the integrity of the central control system, is easily con nected to the machine without disturb ing factory wiring. In addition, a remote sound or light alarm can be easily field installed to alert you, should a safety light be tripped on the indicator panel. Only a simple two-wire hook-up is

required.

Selective insulation

The 19 Series machines are adequately insulated at the factory to meet most application demands. However, addi tional insulation packages are available for specific machine applications.

Isolation assembly

A combination of soleplates, jacking

screws, leveling pads and neoprene

pads are available in isolation packages. Specify this option for installations

requiring special mounting. Isolation pads are shipped at no charge.

Remote control set point

Select or alter machine chilled water temperature from a remote location by specifying this optional solid state control.

Pumpout unit

Factory mounted, complete with starter, controls and all necessary inter connecting refrigerant piping. Permits easy transfer of refrigerant between machine and storage tank. Speeds servicing and minimizes downtime. On multiple machine applications, a single pumpout unit saves first costs. Not required for R-ll units.

Lead-lag control

Desirable when two or more machines are installed in series or parallel. Cen tralized control features the following capabilities;

• parallel operation

• series operation with split or common point control

• two or more chiller operations

• uneven sized chillers working together

• independent control of chillers both manually and automatically

• automatic lead-lag operation

• reassignment of lead-lag hierarchy

• automatic standby Panel lights indicate system operating

mode.

Hot gas bypass

When a machine is expected to run at light load and elevated condensing tem peratures or at minimum load for ex tended periods of time, a hot gas bypass is recommended. The hot gas bypass is factory mounted and wired, manual or automatic. It virtually eliminates com pressor surging at extreme part-load conditions and smooths out the ma chine’s full operating cycle, whatever the load fluctuation.

Additional energy-saving options

Chilled water self-reset control

This device permits the leaving chilled water tempera ture to rise as the load on the machine decreases. The higher the leaving chilled water temperatures, the less work the compressor is forced to do.

The power monitor control

An electronic, energy-saving device which continuously monitors building electric demand and sheds preselected

loads in stages during peak power usage periods. The power monitor control reduces power consumption and minimizes power demand charges.

Chilled water reset-dual input

A device that causes the leaving chilled water tempera ture control set point to change in proportion to a change in a remote temperature such as return chilled water or outdoor air temperature.

Adjustable stepped-rcset control

A device that permits leaving chilled water tempera ture to rise in predetermined adjustable steps. Operator is in control of demand limit so amount of reset is not dependent on machine load but on the amount of change of resistance in the probe circuit.

Stepped power demand limiter

This option makes it possible to limit power demand in four ways:

1. At start-up each chiller can be held to a preselected maximum current draw for any time period of up to one hour.

2. During normal operation, chiller load can be auto matically reduced in up to 3 stages in response to increased total building power consumption.

Chiller demand can semi-automatically be lowered in

3. a single stage in response to increased total building power consumption.

Chiller demand can also be lowered manually.

Stepped power demand limiter minimizes the likeli hood of getting demand charges. Also has timer which increases flexibility of operator. Operator can change demand limit without being at controls and can also adjust demand limit manually.

Part-load energy requirements

At part load, chiller energy requirements are aifected by many variables, such as degree of load, chilled water flow, condenser water flow, entering condenser water tempera ture, leaving chilled water temperature, and the percentage of compressor loading at design conditions.

Because of these many variables, a typical part-load curve (% Standard Rating Tons versus % Standard Rating Kw Input) may have appreciable inaccuracies when applied to a specific chiller and set of conditions. Carrier, therefore, does not recommend the use of such curves in making operating cost studies.

Instead, thru computer analysis. Carrier will provide

you with accurate and detailed information on the energy

requirements for your selected chiller at the expected

jobsite conditions.

Energy savings can be significant if the chiller can be

operated with a relatively low entering condenser water

temperature. And, since conditions of design load and

design wet-bulb temperature can occur rather infrequently,

the opportunity for such savings exists during most of the

operating season. Each chiller is capable of operating

efficiently with entering condenser water temperatures down to 55 F (13 C). This capability assures you of both energy conservation and excellent part-load performance,

because “custom-made chillers” give the best part-load

performance.
