1 Scope This standard applies to positive displacement refrigerant compressors for stationary and mobile refrigerating systems and heat pumps defined in 3.1, hereafter called compressors. It applies for compressors used in commercial and industrial appliances and with electrical energy supply including integral motors, up to 1 000 VAC and 1 500 VDC. It applies to open drive, semi hermetic and hermetic motor compressors, which contain a positive compression function. This standard is not applicable to:
— compressors used in household appliance for which EN 60335‑2‑34 applies;
— compressors using water or air as refrigerant.
This standard does not deal with requirements for vibration and noise.
NOTE 1 Compressors for automotive comfort air conditioning systems can be developed according e.g. SAE J 639.
NOTE 2 Noise emission depends on the complete installation of the built-in compressors and the corresponding operating conditions.
For semi-hermetic and open drive compressors which include moving parts and for which the external envelope is primarily designed for mechanical loads, thermal loads (to limit the possible deformation due to temperature), stiffness of the structur...
