Because the carbon dioxide used in car air conditioning is a recycled industrial waste product, it is an environmentally neutral solution. The Alliance claims that using a CO 2-based air conditioning system will reduce total car emissions by 10%, thereby sparing the planet 1% of total greenhouse gases. [citation needed]
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]
The efficiency of air conditioners is often rated by the seasonal energy efficiency ratio (SEER), which is defined by the Air Conditioning, Heating and Refrigeration Institute in its 2008 standard AHRI 210/240, Performance Rating of Unitary Air-Conditioning and Air-Source Heat Pump Equipment. [61]
The coefficient of performance or COP (sometimes CP or CoP) of a heat pump, refrigerator or air conditioning system is a ratio of useful heating or cooling provided to work (energy) required. [1] [2] Higher COPs equate to higher efficiency, lower energy (power) consumption and thus lower operating costs. The COP is used in thermodynamics.
Air-conditioner sizes are often given as "tons" of cooling, where 1 ton of cooling equals 12,000 BTU/h (3.5 kW). 1 ton of cooling equals the amount of power that needs to be applied continuously over a 24-hour period to melt 1 ton of ice. The annual cost of electric energy consumed by an air conditioner may be calculated as follows:
