SR EN 12693:2026

This document is applicable to positive displacement refrigerant compressors for stationary and mobile refrigerating systems and heat pumps, hereafter called compressors. It is applicable 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 is applicable to open drive, semi hermetic and hermetic motor compressors, which contain a positive compression function. This document is not applicable to: - compressors used in household appliance for which EN IEC 60335-2-34 applies; - compressors using water or air as refrigerant; - compressors in vehicle air conditioning systems covered by a specific product standard, e.g. ISO 13043. This document does not deal with requirements for emission of 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 inc
