F Gas CO2 Equivalent Calculator

F Gas CO2 Equivalent Calculator

Please select the type of F Gas from the dropdown list and enter the mass of the gas (weight of gas in KGs) and select Calculate. These are required fields.

The F Gas CO2 equivalent in Tonnes and the Leak Test Frequency will be displayed

Calculated Results

The results display the Tonnes CO2 Equivalent (otherwise referrred to as t CO2 eq) and the frequency that leak testing should be carried out.

The Future for Refrigerant Gasses

Benefits of using R32 gas
  • R32 is a low global warming potential refrigerant (GWP) of 675
  • Compared to other common refrigerants such as R410A with a GWP 0f 2088
  • Uses up to 20% less refrigerant than R410A, R410A does not deplete the ozone layer, however, it is a powerful greenhouse gas which contributes to climate change.
  • Single component refrigerant easy to recycle
  • Zero ozone depleting potential
  • More energy efficient lower carbon emissions and energy costs
Timeline
From 2015

It will be illegal to use Hydro chlorofluorocarbons (HCFCs), including the ozone-depleting refrigerant gas R22, in refrigeration, heat pump and air conditioning systems. R22 is commonly used in AC systems pre-dating 2004 and so its ban will have a major effect on air-conditioning costs.

Gases with high Global warming potential
From 2020
  • HFCs with global warming potentials of more than 2,500 will be banned in all refrigeration systems. This will mainly affect the use of HFC 404A and R507 in commercial and industrial refrigeration systems.
  • The only exception will be for use in systems that cool products to below -50 degrees Celsius (°C)
From 2020
  • From 2020 HFCs with global warming potentials above 150 will be banned in movable air-conditioning equipment. Air conditioning equipment is movable if the end user can move it between rooms.
From 2025
  • F gases with a global warming potential above 750 will be banned in ‘single split’ systems that contain less than 3 kg of refrigerant. Single split systems involve one cooling coil connected to a remote condensing unit.
  • There are no bans for larger air-conditioning or heat pump systems, e.g. chillers or larger split systems.
