Any type of compressor has its operating limits. When using a compressor, it must be strictly ensured that the compressor operates within the manufacturer's specified operating limits. Otherwise, long-term operation of the compressor under harsh conditions will cause damage to the compressor. To achieve lower evaporating temperatures or higher condensing temperatures, necessary technical measures must be taken to expand the operating limits of the compressor. The compressor is only allowed to operate within the operating limits shown in the diagram. Please pay attention to the technical measures within the limit area. The design conditions should not be close to the limit values, and the compressor should not operate continuously near the limit values to prevent high temperature carbonization, motor overload, insufficient motor cooling, poor lubrication, efficiency degradation, vibration, noise, deformation, and engagement issues. Operating with an economizer (ECO) for high pressure ratio low-temperature systems (of course, high-temperature systems with high pressure ratios can also be used, depending on the input-output recovery period) generates subcooling and staged compression, increasing the refrigeration capacity and greatly improving system efficiency. For further information on economizer parameters, please consult the manufacturer. The use of variable frequency drives (VFDs) will impose additional limitations on the operating limits of the compressor. For further clarification, please consult the manufacturer. Performance data may significantly differ from the data in this product catalog under conditions of liquid subcooling or changes in suction temperature. The data in this product catalog is applicable for operation at 50Hz. For operation at 60Hz, the data provided in this sample can be multiplied by a factor of 1.2. The maximum operating current remains unchanged.
