a company with engineering excellence ...

Thermax, a technology driven company has been in the core sectors of

for more than 25 years and has

defined its business as -

Electricity is scarce and expensive. It should be used

only where it is irreplaceable. Keeping this in mind, Thermax took up

the challenge of finding an alternative for traditional electrically

operated compression chillers. About a decade ago, Thermax

introduced the revolutionary concept of

for air-conditioning and process cooling requirements, in India.

Considering the growing demand for Vapour Absorption Chillers,

Thermax set up its state-of-the-art manufacturing plant in 1988, in

India at Pune which has been awarded the ISO 9001 and the ISO 14001

certificates. Needless to mention, these chillers conform to

international standards. To maintain these high standards, a team of

workers and engineers is specially trained and exposed to global work

and quality culture. With this positive and innovative attitude, Thermax

has carved a niche in the global market where competition is stiff and

performance is the only criteria.

Thermax sales and after-sales service is efficient, responsive and

responsible. Our Engineers understand customer requirements, design

the most optimal solutions and ensure quality at every stage, to achieve

customer delight.

are equipped with a unique auto de-crystallization circuit to virtually eliminate any

chances of crystallization. Also these chiller-heaters are equipped with a magnetic valve which

opens and the refrigerant is dumped into the absorber to reduce the concentration if the dilute

solution temperature goes below the set value.

chiller-heaters utilize special tubes, monobloc burners and other accessories which

make the unit very compact. This compact design reduces the overall floor space requirement.

chiller during operation, is purged continuously into the storage tank, thereby maintaining high vacuum in

the shell. The non-condensable gases collected in the storage tank can be purged periodically.

The cross-over piping from absorber to condenser is a standard feature in . It reduces the piping

EcoChill incorporates a state-of-the-art programmable logic controller, which

incredibly enhances its flexibility and reliability. It brings along all the advantages

of a solid state control system. Elimination of rigid electro-mechanical control

components promises enhanced reliability and fail safe operation, which reduces

maintenance and ensures minimum downtime of the unit.

Control system allows the user to log parameters noted in the last one week, at a

sampling time of one hour. During a trip condition, the data is logged at a faster,

adjustable sampling time. Also a log of last six alarms with date and time stamp is

maintained.

Client can programme the units operating schedule as per his convenience so that

the it is switched on or switched off as per the programmed schedule. This

schedule can be set by the customer anytime.

Thermax Control system provides a host of diagnostic information such as

hardware related faults, trip causes, sensor errors, pump errors and data history

regarding previously occurred faults and alarms. This equips the operator with an

overview of the unit and adequate data for faster and easier troubleshooting and

routine maintenance.

Unique 2 line display, keypad and the software constitute a user-friendly operator

interface. The operator can easily control the functions, with the aid of self-

explanatory messages appropriately displayed on the screen. The status screen

provides audio-visual alarms and displays warnings about any abnormal conditions

in the unit function. This alerts the operator, specifying the abnormality, to initiate

the necessary action.

Thermax manufactures these environment friendly and

energy efficient Vapour Absorption Chiller-heaters at its

plant in Pune, India in technical collaboration with

Kawasaki Thermal Engineering, Japan. Its state-of-the-art

manufacturing facility is awarded with ISO 9001 and ISO

14001 certificates. Stringent quality control procedures

alongwith a skilled workforce ensure that a highly reliable

product leaves the factory. The equipment and

manufacturing processes conform to the best International

standards.

Thermax’s manufacturing capabilities are confirmed by the

fact that over the years Thermax has installed many chillers

in countries like Germany, UK, Spain, Italy, Middle East,

South East Asia with the product conforming to the

respective country standards like CE, TUV, DNV, ISPESL,

ASME, etc.

The units can be performance tested under the simulated

site conditions before it leaves the factory. The factory

assembled and tested unit considerably reduces the time

needed for installation and commissioning on the site.

fuel driven absorption chiller-heater

As the Vapour Absorption Chillers work under vacuum conditions, the manufacturing of these chillers is very critical with

respect to leak tightness. Hence it is necessary to follow stringent quality control procedures and also perform leak detection

tests. Understanding the importance, Thermax carries out the leak detection test in the following sequence :

Nitrogen is charged into the shell side of the chiller upto 1.3 to 1.4 kg/cm g pressure and soap solution is sprayed on all the

joints and expanded tube ends. In case of leakage, Nitrogen leaks out, forming soap bubbles, indicating the leak points.

The unit is kept under pressurized condition for 24 hours, by charging it with Nitrogen upto 1.3 kg/cm g pressure on the

shell side. In case of leakage, Nitrogen escapes out, resulting in drop in Nitrogen pressure inside the chiller, indicating

leakage.

Helium, the next smallest molecule after Hydrogen, can leak through very minute holes. In this test Helium is sprayed on all

the joints of the chiller. As the chiller is under vacuum conditions, leakages, if any, will result in Helium entering into the

chiller and thus will be displayed on the screen of Helium leak detector. The joints are marked for repairs.

In this test, the chiller is fully covered by a polythene sheet and Helium is passed from below, to observe the cumulative leak

rate of the entire chiller.

When maintained at high vacuum, water will boil and flashcool itself.

Concentrated Lithium Bromide solution has affinity towardswater. The solution absorbs vapourised refrigerant water.

As Lithium Bromide becomes dilute it loses its capacity to absorbwater vapour. It thus needs to be reconcentrated using a heat source.

The basic operation cycle of the single effect vapour absorption

chiller.

This heat causes the solution to release the absorbed refrigerant in the form ofvapour. This vapour is cooled in a separate chamber to become liquid refrigerant.

Opera t ing Pr inc iple :

The vapour absorption chiller-heater produces chilled

water upto 5 C, utilizing fuel as the driving source. The

chiller utilizes the latent heat absorbed by the

refrigerant (water) as it evaporates (in a closed pressure

vessel) for cooling. Unlike a compression chiller which

uses a compressor to pressurise the vapourised

refrigerant (Freon) and condenses it by using cooling

water, the absorption chiller uses an absorbent (LiBr)

to absorb the vapourised refrigerant (water). The

refrigerant is then released from the absorbent when

heated by an external source like fuel.

o

Basic Pr inc iple :

Boiling point of water is a function of pressure. At

atmospheric pressure, water boils at 100 C. At lower

pressure it boils at lower temperature. The boiling point

of water at 6 mm of mercury absolute, is only 3.7 C.

o

o

Lithium Bromide (LiBr) salt has the property to absorb

water due to its chemical affinity. It is soluble in water.

As the concentration of LiBr increases, its affinity

towards water increases. Also as the temperature of

LiBr increases the affinity decreases.

There is a large difference between vapour pressure of

LiBr and water.
