Control of Refrigerant Discharge
By international agreement, the worldwide use of certain refrigerants will be reduced in stages. To this end,
listed below are suggestions on how refrigeration engineers can contribute by the discontinuing of releasing any
refrigerant gas to the atmosphere.
Release of refrigerant to the atmosphere is an offence under Section 33
of the Environmental Protection Act 1990.
DO NOT . . . DO . . .
(1) Blow off refrigerants to atmosphere. (1) Pump down into a receiver or empty cylinder using
Reclaim Equipment.
(2) Use refrigerants to clean coils etc. (2) Clean coils etc. using a hand brush, vacuum or
compressed air.
(3) Leak test using pure refrigerant. (3) Leak test using Nitrogen and just a trace of refrigerant
gas.
(4) Recharge before mending leaks. (4) Find and mend leaks before recharging system.
(5) Dispose refrigerant gas to waste. (5) Send used refrigerant gas back for reprocessing.
Note: Disposal of refrigerants must be closely controlled. To dispose of refrigerant or a refrigerant
system an approved agent must be used. If you have any doubt contact Denco Limited.
Log Book
In order to comply with BS EN 378, the user should keep an updated log book of the Compressed Air Dryer.
The log book should record:-
(a) The details of all maintenance and repair work.
(b) The quantities of new, re-used, or recycled refrigerant which have been charged on each occasion, and the
quantities of refrigerant which have been transferred.
(c) Any analysis of re-used refrigerant.
(d) The source of re-used refrigerant.
(e) Changes and replacements of components of the system.
(f) The results of all periodic routine tests.
(g) Significant periods of non-use.
The log book should be kept in the machinery room or stored in a computer system. It must be accessible to the
competent person when servicing or testing.
