Talk Details: 

The Indian Society of Heating, Refrigerating and Air Conditioning Engineers (ISHRAE), was founded in 1981 at New Delhi by a group of eminent HVAC&R professionals. ISHRAE today has more than 12,000 HVAC&R professionals as members and additionally there are 7,500 Student-members. ISHRAE operates from 41 Chapters and sub Chapters spread all over India, with HQ in Delhi. It is led by a team of elected officers, who are members of the Society, working on a voluntary basis, and collectively called the Board of Governors.

The expert speaker briefed about different cooling techniques which are in practice and those which are under deployment. The topics include Data Center Trends and Cooling Trends, Cold Wall, Modular Data Center, Secure Power and Rack Solutions.

Humidifiers are required in data centers to prevent electrostatic discharge damaging servers and offer high capacity, low cost evaporative cooling. For existing data centers ASHRAE recommends a humidity level of 5.5°C dew point to 60%RH and an allowable range of between 20-80%RH. In most parts of the world, at some time in the year, humidification will be needed to meet these internal conditions. Humidifiers are often used alongside free air cooling systems to either boost the cooling capacity with an evaporative cooling effect or provide high load, low cost humidification to the large volume of air flowing through the data centre’s ventilation system. Using variable-speed CRAC units instead of fixed-speed ones is another option: The CRAC units only run at the speed required to maintain the desired temperature. CRAC units operate most effectively when running at 100%, so some variable-speed systems are not fully optimized when operating at partial load
