Ozone depletion potential ODP detection

Ozone depletion potential ODP refers to ozone depletion potential (ozone decay index), which is used to examine the potential impact of a substance's gas dissipation into the atmosphere on ozone destruction. The smaller the ODP value, the better the environmental characteristics of the refrigerant. The ODP value illustrates the degree of damage to the atmospheric ozone layer by different chemical substances.

Zhongke Testing provides ozone depletion potential ODP testing services.

ODP (Ozone Depletion Potential, ozone depletion potential) represents global warming potential and is a value that describes the ability of a substance to destroy stratospheric ozone. ODP represents the ratio of the ability of chlorofluorocarbons in the atmosphere to destroy the ozone layer to the ability of R11 to destroy the ozone layer. The ODP of R11 is 1.0. The smaller the ODP value, the better the environmental characteristics of the refrigerant. According to current levels, refrigerants with an ODP value less than or equal to 0.05 are considered acceptable.

Different ozone depleting substances ODS have different depletion capabilities of the ozone layer. When they escape into the atmosphere and gradually diffuse from low altitude (troposphere) to high altitude (troposphere), some perchlorofluorocarbons do not change in the troposphere, but in the troposphere, they are decomposed by short-wave ultraviolet radiation, which triggers a reaction that destroys the ozone layer.
And some hydrogen-containing chlorofluorocarbons have interacted with HO abundant in the atmosphere in the troposphere. Free radical decomposition reactions occur. They do not live long in the stratosphere, so only a small number can diffuse into the ozone layer. The ability to destroy the ozone layer is also greatly reduced. In order to express and compare their ability to ozone, the concept of ozone depletion potential (English name: Ozone depletion potential, referred to as ODP) is adopted. Using CFC-11 as the benchmark comparator, its ODP value is set to 1. The ODP value of other substances is expressed by the fractional value whose ozone depletion capacity is greater or smaller than that of CFC-11.
