The programme scope covers air-cooled and water-cooled stationary condensing units designed for low (LT) and/or medium (MT) temperature applications in the field of commercial and industrial refrigeration.
The certification programme is applicable to condensing units using the following refrigerants:
The scope is limited to the following refrigerating capacities comprised between
In the present CDU programme, the definition from regulation 2015/1095 applies: product integrating at least one electrically driven compressor and one condenser, capable of cooling down and continuously maintaining low or medium temperature inside a refrigerated appliance or system, using a vapour compression cycle once connected to an evaporator and an expansion device.
Low temperature application (LT)
Is referred to as “low temperature application” or LT an application where the condensing unit is capable of delivering its rated refrigerating capacity at a saturated evaporating temperature of -35 °C.
Medium temperature application (MT)
Is referred to as “medium temperature application” or MT an application where the condensing unit is capable of delivering its rated refrigerating capacity at a saturated evaporating temperature of -10 °C.
Rated refrigerating capacity
Is referred to as “rated refrigerating capacity” the refrigerating capacity delivered by the condensing unit at full load and for the following temperature constraint :
