Voltas produced India's first window air conditioner with DC-inverter-based variable-speed motors. [10] DC Inverter Technology is an innovative technology that provides superior cooling while reducing the frequency of turning the compressor on and off. This helps in reducing the power consumption to a greater extent. [11]
Sanyo worked with Energy Efficiency Services Limited to develop a 1.5-ton inverter air conditioner (AC) with an Indian Seasonal Energy Efficiency Ratio (ISEER) of 5.2. Distribution of these air conditioners began in September 2017. [39] On April 4, 2019, Sanyo launched a new AC range exclusively on Amazon. [40] [41]
Blue Star was founded in 1943 by Mohan T Advani as a reconditioning company. [4] [5] Soon after inception, Blue Star ventured into the manufacturing of ice candy machines and bottle coolers and began the design, execution of central air conditioning projects, followed by the manufacturing of water coolers.
Innovations in the latter half of the 20th century allowed more ubiquitous air conditioner use. In 1945, Robert Sherman of Lynn, Massachusetts, invented a portable, in-window air conditioner that cooled, heated, humidified, dehumidified, and filtered the air. [37] The first inverter air conditioners were released in 1980–1981. [38] [39]
The Indian Society of Heating, Refrigerating and Air Conditioning Engineers (ISHRAE) was established to promote the HVAC industry in India. ISHRAE is an associate of ASHRAE. ISHRAE was founded at New Delhi [58] in 1981 and a chapter was started in Bangalore in 1989. Between 1989 & 1993, ISHRAE chapters were formed in all major cities in India.
A power inverter, inverter, or invertor is a power electronic device or circuitry that changes direct current (DC) to alternating current (AC). [1] The resulting AC frequency obtained depends on the particular device employed. Inverters do the opposite of rectifiers which were originally large electromechanical devices converting AC to DC.

Currently used in residential and commercial air-conditioners and heat pumps. R-134a HFC-134a CH 2 FCF 3: 1,1,1,2-Tetrafluoroethane: 3790 1550 Widely used Most used in 2020 for hydronic heat pumps in Europe and the United States in spite of high GWP. [58] Commonly used in automotive air conditioners prior to phase out which began in 2012. R-410A
Monocrystalline solar cell This is a list of notable photovoltaics (PV) companies. Grid-connected solar photovoltaics (PV) is the fastest growing energy technology in the world, growing from a cumulative installed capacity of 7.7 GW in 2007, to 320 GW in 2016. In 2016, 93% of the global PV cell manufacturing capacity utilized crystalline silicon (cSi) technology, representing a commanding lead ...
