Terms
Conditioned space — Space within a building provided
with heated or cooled air or both (or surfaces) and,
where required, with humidification or dehumidification
means to maintain conditions for an acceptable thermal
environment.
Decommissioning — Means the final shut-down and
removal from operation or usage of a product or piece
of equipment containing fluorinated greenhouse gases.
Discharge Pressure — Referring to the pressure leaving
compressor
Reclamation — Means the reprocessing of a recovered
fluorinated greenhouse gas in order to match the
equivalent performance of a virgin substance, taking
into account its intended use.
Recovery — Referring to the collection and storage of
fluorinated-greenhouse gases from products (including
containers and equipment) during maintenance or
servicing or prior to the disposal of the products or
equipment.
Recycling — Referring to the reuse of a recovered
fluorinated-greenhouse gas following a basic cleaning
process.
Repair — Referring to the restoration of damaged or
leaking products or equipment that contain, or whose
functioning relies upon, fluorinated-greenhouse gases,
involving a part containing or designed to contain such
gases.
Suction Pressure — Referring to the pressure entering
compressor
