Introduction
CCl2F2
Ice Harvesting in Massachusetts, early 1850’s

newspaper ad.
In the late 1920’s CFC replaces
ammonia (NH3), chloromethane (CH3Cl) and
sulfur dioxide (SO2) as a refrigerant

Some Facts and Figures
� HVAC market size: approx. 100 bn USD
� HVAC sector accounts for roughly 40% of commercial building energy
consumption worldwide
� China manufactures approx. 100 mn split air-conditioning units per year
(growing at about 14% p.a. over the last 5 years)
� Sales of air-conditioner in India approx. 3.1 mn units in 2013/14
(expected to grow by 10-12 % p.a. in the next 5 years)
� AC penetration (AC per capita) approx. 30% (100 mn units)
� AC penetration (AC per capita) approx. 3% ( 40 mn units)

Final Remarks� China HPMP includes conversion of 18 out of 32 production lines to HC-290 till 2015
(will lead to the introduction of millions of HC-290 ACs in the market)
� So far about 100,000 HC-290 split ACs introduced in India
� Service history, feedback, quality database and safety analysis implies high success
� General, use of HCs
— Impose new responsibilities on manufacturers for safe production practices
— Requires additions and changes to the existing production processes
— Products must be designed for safety, capacity and efficiency
— Infrastructure must be established to ensure safe environment
— Re-training of technicians must be concurrent with development processes
— Flammability risk is extremely low; >10,000 times below background fire risk
— Risk to S&M technicians also miniscule
� Compared to competing products, HC-290 has lower TEWI, low- to medium cost (per
kW) and higher efficiency
� Activities are ongoing to expand the range of products
� Developments include designs for greater integrated safety to further reduce the
flammability risk
