1.4 Handling of Refrigerant

When handling refrigerants, all legal provisions and guidelines must be complied
with. Only qualified personnel may perform these activities.

The operator of the process cooler is responsible for the proper disposal of used refrigerants
and system parts.

1.5 Safety Requirements

Safety requirements concerning the operation of refrigeration systems within the
European Union.

The following information applies to refrigeration systems with closed refrigeration cycles that
are used within the European Union. In some member states additional requirements may
apply, e.g. due to environmental considerations.

In these refrigeration units working pressures occur that are subject to the regulations laid
down in the Pressure Vessel Directive 97/23/EC and European standard EN 378 (Parts 1 – 4,
version September 2000).

Apart from the requirements relating to the design, equipment and testing of the refrigeration
systems prior to delivery to the customer, also the operator of such systems has to comply
with requirements in accordance with European standard EN 378 and/or additional national
regulations. These concern the 

installation,

 the 

operation 

and 

regular testing

 of

refrigeration systems.

1.5.1 Installation

If the process cooler is installed below ground level or on upper floors of a building, without any
adequate number of emergency exits, installation site requirements relating to the protection of
people in accordance with EN 378 have to be complied with.
With respect to the actual refrigerant charge of the process cooler, a minimum room volume
must be maintained and not be fallen short of.

Process Cooler

Cooling system 12 kW

Minimum room sizes in [m³] are required for the installation of refrigeration units, depending on
the refrigerant being used.

It can thus be ensured that in the case of refrigerant leaks caused by damage to the equipment
- and thus the displacement of oxygen - will not have any detrimental effect on the health of
people.
