due on 10th and 11th of May for which preparation by DCI and its sub chapters is going on.
After the 3rd successful event of Ventconf - 2013, a one day conference exclusively on
ventilation, the 4th Ventconf - 2014 is also finalized. This time the conference will be of two
days. Its team is finalized and responsibilities to team members have also been
distributed. Its preparation has started in top gear with the finalization of dates as 14th and

on ventilation system where experts from India and abroad will share their knowledge and
experience through a series of workshops and lectures over two days, and will cover all the
areas of ventilation, evaporative cooling, industrial ventilation, kitchen ventilation etc.
Another event of DCI, Acreconf - 2015 also has taken start by its first meeting with core
committee member on 28th April at IHC. The interest of people is increasing in this event
year after year and so the expectations are also rising.
This event of two days on HVAC remains full of activities, lectures workshops on almost all
topics delivered by experts of the industry both from India and Abroad. To cover all the
areas of HVAC, six parallel session are allowed to run.
As the country is progressing in all directions, DCI also progressing and trying to meet the
expectations of all its members to cover all areas in HVAC industry. This issue of Twitter will
also cover some of your area of HVAC and will benefit to the readers.
This Issue covers the period of Jan 2014 to April 2014

Economical way of meeting cooling demand of spaces having variable internal sensible load
Some spaces in use have very extraordinary internal
sensible load and because of that the demand of
airconditioning keeps on fluctuating and due to this
fluctuating it becomes very difficult to control the inside
conditions i.e. temperature and humidity both. It
requires special equipments of HVAC to install and
provide airconditioning to meet the demand which is
normally costly in capital cost and running cost both. If
these special units are not provided the area which is
being airconditioning will not serve only its purpose but
also uncontrolled conditions can damage the
equipments inside and spoil the complete process.
