1. General features
The two main heat exchangers in refrigeration machines and heat pumps are the evaporator and the condenser, but there may also be additional heat exchangers designed to improve cycles, such as sub-coolers or heat recovery desuperheaters.
The main types of exchanger used are :
finned batteries ;
minichannel exchangers ;
immersed heat exchangers ;
trickle exchangers ;
multi-tube exchangers ;
coaxial exchangers ;
plate heat exchangers.
There are also other, more specific types, built to order, for particular applications such as rotary drum freezers, scraped surface exchangers for ice...

Regulations
Pressure equipment regulations
In the past, it was defined by a decree of 1943, subsequently revised in 1960. As part of the harmonization of technical regulations, the European Union has issued a Pressure Equipment Directive (PED) (no. 97/23), which becomes the only rule in force in each member state; for France, the transcription is the subject of a decree and order no. 99-1046 of 13/12/1999.
