Mobile air conditioning R134a (1430) 150

What are the Kyoto gasses?

The Kyoto basket encompasses the following six greenhouse gases: carbon dioxide (CO2), methane (CH4), nitrous oxide (N2O), and the so-called F-gases(hydrofluorocarbons and perfluorocarbons) and sulphur hexafluoride (SF6).

What is the difference between Kyoto and Montreal Protocol?

What is the difference between Montreal and Kyoto Protocol? While the Montreal Protocol was established to phase out substances that deplete ozone, the Kyoto Protocol was set in place to reduce the emissions of greenhouse gases, with the exception to ozone depleting substances.

Where are refrigerants used?

A refrigerant is a working fluid used in the refrigeration cycle of air conditioning systems and heat pumps where in most cases they undergo a repeated phase transition from a liquid to a gas and back again.

What is the importance of Kyoto Protocol?

In short, the Kyoto Protocol operationalizes the United Nations Framework Convention on Climate Change by committing industrialized countries and economies in transition to limit and reduce greenhouse gases (GHG) emissions in accordance with agreed individual targets.

What is the most used refrigerant?

HCFC-22 (R-22) has been the most popular refrigerant for residential heat pump and air-conditioning systems for over four decades. Unfortunately, if it leaks it contributes to ozone depletion. It is also a greenhouse gas and its manufacture gives a by-product HFC-23 that contributes to global warming.

Which substances are regulated by the Kyoto Protocol?

The Kyoto protocol covers six categories of greenhouse gas (GHG) emissions: carbon dioxide (CO2), methane (CH4), nitrous oxide (N2O), hydrofluorocarbons (HFCs), perfluorocarbons (PFCs) and sulphurhexafluoride (SF6).

What is the main features of Kyoto Protocol?

The major feature of the Kyoto Protocol is that it sets binding targets for 37 industrialised countries and the European community for reducing greenhouse gas (GHG) emissions. These amount to an average of five per cent against 1990 levels over the five-year period 2008-2012.

Why R-134a is not used in AC?

R134a systems operate at higher discharge-side pressures than R12, which can cause compressor seals to leak. Bottom line, R134a simply doesn’t cool as well as R12. In addition, there was the lubricant issue. Because A/C compressors have moving parts, they require oil.

Which refrigerant is better R-32 or r410?

R410A has a high VCP, which requires larger pipes. Thus, it’s not as efficient as R32, whose VCP is significantly lower. Moreover, R32 has a higher pressure ratio than R410A. Overall, R32 is much more efficient than R410A.
