Carbon Dioxide (CO2) in Refrigeration and Air-Conditioning Systems (RAC)
Carbon dioxide (CO2)1 was one of the first refrigerants to replace early air cycle systems and was in use primarily for shipboard refrigeration in the beginning of the twentieth century. It was then superseded by chlorofluorocarbons. However, since CO2 is environmentally benign, non-toxic (in the classical sense), non-flammable, chemically inactive and offers a very high volumetric cooling capacity together with excellent heat transfer properties, it is increasingly considered for use today in RAC systems.
Containment of Refrigerant Compressors
ASERCOM member companies are always concerned by any refrigerant leakages from systems and strive to work with partners to achieve the best possible system containment at all times. Leakages, in addition to impairing system performance can, in the case of HFC's, have a direct effect on global warming, and in the case of other refrigerants can have a detrimental and possibly dangerous effect on the immediate environment.
Electromagnetic Compatibility Directive 2004/108/EC
ASERCOM has examined whether its members should affix the “CE marking” and issue the “EC Declaration of Conformity” with reference to the Electromagnetic Compatibility Directive – EMC.
Energy Efficiency Rating
ASERCOM members have been energy conscious for years. All developments are showing significant improvements in compressor energy efficiency. With regard to the demand of the KYOTO Protocol and related energy saving measures (e.g. EU ErP Directive 2009/125/EC) ASERCOM members contribute to the reduction of CO2 emissions by continuing to work on further improvement.
Recommended liquid line filter dryers and moisture indicators for refrigeration and air conditioning systems with HFCs refrigerants and POE lubricants
The introduction of HFC refrigerants, which are not miscible with traditional mineral oil and Alkylbenzene lubricants, has created the requirements for Polyol ester (POE) lubricants. POEs have some inherent characteristics that require special attention when using the lubricant.
Hydrocarbon (HC) Refrigerants in Refrigerating Systems
Hydrocarbons have proven to be suitable refrigerants in several applications - regarding thermodynamics and reliability. ASERCOM member companies have collected experience with their use in different fields and are engaged in standardization work to enable appliance and system manufacturers to use HCs as refrigerants in a safe but restricted way.
Machinery Directive 2006/42/EC
ASERCOM has examined the implications of the revised Machinery Directive 2006/42/EC (MD) regarding compressors and condensing units produced by ASERCOM members.
Pressure Equipment Directive 97/23/EC
On May 29, 1997 the European Parliament and the Council of the European Union adopted Directive 97/23/EC on the approximation of laws of the Member States concerning Pressure Equipment (PED). ASERCOM has involved a Notified Body in the interpretation and implementation of this directive with respect to compressors produced by ASERCOM members.
Capacity Rating of Thermostatic Expansion Valves
This statement provides common definitions of terminology and rating conditions for thermostatic expansion valves within the European refrigeration and air conditioning market.
The regulation EU2037/2000 gradually prohibits the use of HCFCs. Virgin HCFCs are already banned, and the use of recycled HCFC will finally be prohibited via a complete ban as of January 1st, 2015.
