CFCs and HCFCs have been used extensively in major refrigeration and air-conditioning applications for the past few decades. These refrigerants, however, were known to be responsible for the stratospheric ozone layer depletion and hence in 1987 ‘Montreal protocol’ was signed for the control of ozone depleting substances (ODSs) and now most of the countries are subject to the rules of the protocol for various activities related to the ODSs. For the past few years, non-ozone depleting HFC refrigerants have been developed and applied to some fields. The Kyoto Protocol of 1997 for the climate change, however, defined HFCs as one of the greenhouse warming substances. Therefore, at present there is a growing consensus that HFCs will not be used in refrigeration systems in the long run. In order to solve these environmental problems fundamentally, natural refrigerants should be used.
Ecogasrefrigerants supply both pure and mixed hydrocarbon refrigerants of more than 99.9% purity. We are dedicated to meet all the needs of various customers and eventually will become a leading environment conscious company for the wellbeing of mankind.
In fact, to reflect this trend isobutane hydrocarbon refrigerant(R600a) has been used extensively for refrigerators in Europe and Japan. Korea also adopted isobutane for this purpose. Recently, many multinational corporations such as Coca Cola, Pepsico, Unilever announced that they will use Hydrocarbon refrigerants in their equipment.
Hydrocarbon refrigerants are natural fluids with no ozone depletion potential (ODP). They also offer very low global warming potential (GWP) of <3 while those of HFCs are
1,300 ~4,400 (GWP). They also offer other advantages such as 40~50% reduction in charge, 5~10% increase in energy efficiency. Even conventional lubrication oils such as mineral oil can be used.
These refrigerants were listed by ASHRAE (American Society of Heating, Refrigerating and Air Conditioning) as proper refrigerants in various applications.
