1) SALIENT FEATURES OF THERMAX SYSTEM

1] Two stage evaporation ensuring Lowest steam consumption : Thermax

GNxtChill VAHPs comes with two stage evaporation technology which

ensures the lowest specific steam consumption as compared to other

contemporary VAHPs making them the most efficient VAHPs in their

category. The specific steam consumption is as low as 3.7 kg/TR/hr for small

to medium capacity range and 3.5 kr/TR/hr for large capacity range.

This results in substantial benefits to the customer during the entire Life

Cycle of the VAHP in the following ways: Lowest operating cost throughout the life cycle of the VAHP

Lowest water consumption in cooling tower resulting in savings of the

precious water

2] Online concentration measurement and control: Thermax GNxtChill

series is equipped with the state of the art Real-time Online Concentration

measurement which is displayed continuously on the control panel. This

feature is unique to Thermax GNxtChill series VAHPs. This concentration is

continuously compared with the Crystallization Concentration and correctiveactions are taken by the PLC immediately whenever there is any

discrepancy thereby virtually eliminating the Crystallization phenomenon.

This feature is distinctly different from the auto de-crystallization feature

which is Common for all VAHP manufacturers. Please note that this auto

decrystallisation is only a reactive safety (will come into effect only after the

crystallization phenomenon has started) and not a proactive control.

3] Advanced Series flow Technology: Vapor Absorption Technology has got

only 2 major threats Corrosion and Crystallization. Thermax GNxtChill

series comes with the Advanced Series flow technology which ensures that

Crystallization is completely eliminated and corrosion is minimized to the

maximum possible extent. This is mainly possible due to

http://www.pdffactory.com/http://www.pdffactory.com/http://www.pdffactory.com/


4/32


Crystallization : Measurement of concentration online through our unique

Real-time Online Concentration Measurement as explained in point no.2

Corrosion: Corrosion depends on the Lithium bromide concentration and

temperature and leakages. Corrosion rate increases exponentially when

high temperature and high concentration occurs simultaneously. Thermax

has carefully selected Advanced Series Flow Technology (after absorbing

the technical knowhow from Kawasaki and supplying more than 400

machines in Parallel flow and Reverse flow VAHPs) so that highest

temperature of Lithium bromide and highest concentration never occurs

simultaneously. The below table will illustrate the same clearly :

Table below shows comparison of series and para flow for HTG & LTG

Parameter for HTG Unit Para flow

Advanced

Series flow

HTG temperature C 162 155

LiBr concentration % 64-65 60.5

Parameter for LTG Unit Para flow

Advanced

Series flow

LTG temperature C 88 90

LiBr concentration % 62-64 63

Also, the spraying Lithium bromide concentration in the absorber has to be

63% irrespective of the cycle. At 63% concentration the corresponding

crystallization temperature is 34C.

In Advanced Series Flow technology, the Spray solution lithium bromide

temperature (@ outlet of LTHE) is >48C. This wide temperature differential

between operating temperature and crystallization temperature (app. 14C)

ensures that the machine is always far away from the crystallization zone.

This difference is always maintained as we measure the concentration and

strong solution temperature.

In Para flow technology, Spray solution lithium bromide temperature (@

outlet of LTHE) is 40-41C. The temperature differential is very less (only 6-



5/32


7C) between the operating temperature and the crystallization temperature

as compared to the Advanced Series Flow Technology. So, when the

cooling water inlet temperature to the VAHP goes low or if there is any

fluctuation in the load, the Spray solution lithium bromide temperature @

outlet of LTHE reduces thereby making Para flow VAHPs more susceptible

to crystallization.

The above points clearly prove that the claim of Para flow technology

being less prone for crystallization is not true.

4] Invertor control for absorbent pump: Thermax GNxtChill series VAHPs

come with AC drive for the absorbent pumps which ensures that at part

loads, the COP of the VAM improves thereby resulting in improvedperformance of the VAM.

5] Multi stage level control at different locations: It has been proven

worldwide that for efficient and foolproof control of any CRITICAL application

Level controls are a must. Thermax GNxtChill series come with Multi stage

level sensing electrodes in High temperature generator (HTG) , Absorber

and Evaporator.

Advantages of Multistage level control are:

Increase life of solution pumps (absorbent and refrigerant pumps) by

avoiding dry running at any point of time

Ensures excellent and precise control of LiBrand refrigerant,

especially uring fluctuating part load conditions thereby increasing the

COP of the machine under partload.

Crystallization prevention at fluctuating load and low cooling water

inlet temperatures

Most of the other VAM manufacturers opt for mechanical float type control or

level control in HTG and / or Evaporator which is not very accurate and at

fluctuating part load conditions requires frequent resetting.



6/32


6] Vacuum seal Isolation valves for abs/ref Pumps: Thermax GNxtChill

VAHPs are provided with unique Vacuum Seal Isolation valves at the

inlet/outlet of absorbent and refrigerant pumps which ensures that there is

no vaccum breakage required for any maintenance/replacement of the

pumps. With the above valves, any maintenance activity (including

replacement) of the absorbent and refrigerant pumps can be done within

hours.

Other VAM manufacturers provide normal isolation valves (butterfly or gate

type) which are not vacuum seal type. Hence for any maintenance activity

on the absorbent/refrigerant pump, the LiBr has to be removed, the

suction/.discharge line has to be cut to remove the pump, LiBr recharging,

etc which will require 3-4 days time period.

7] Cooling water up to 10 deg C: Thermax GNxtChill VAHPs can operate

even when the cooling water inlet temperature goes as low as 10 deg C.

This is mainly possible only due to Real-time Online Crystallization

measurement.

The purpose of the Vapor absorption machine is to produce chilled water,utilizing the Steam available in the plant. Chilled water thus produced from VAMwill be circulated along the AHUs of the Plant rooms, thus cooling the air flowing

through the AHUs & providing the required Air-Conditioning.. There will be raise intemperature when it comes out of the AHUs. This water will be again taken to theVAM for cooling the water again with the help of refrigerant. As the refrigerantbecomes dilute it loses its capacity to absorb Water Vapor. It thus needs to be re-concentrated using a Heat Source.
