Semihermetic Compressors H - New refrigerants - XP40

Product catalog summary

Introduction
R449A is a new refrigerant with a low Global Warming Potential (GWP), designed as a retrofit for R404A and R507A. It is non-flammable and classified under the A1 safety group, making it exempt from the ATEX Directive. As an HFC-HFO blend, the use of POE oils is recommended, along with regular checks of oil acidity.

Specifications and Recommendations

Glide Effect: R449A has a significant glide of 5K-6K, which requires evaluation of its impact on heat exchanger performance for both new installations and retrofits.
Mass Flow and Pressure: It has lower mass flows and different pressures compared to R404A and R507A, necessitating adjustments to expansion valve settings during retrofits.
Discharge Temperatures: Higher discharge temperatures are observed, especially in low-temperature applications, where additional cooling devices may be necessary.

Application Limits
The document includes a chart detailing the application limits of R449A, specifying conditions for different models and operational scenarios, such as normal operation and conditions requiring head cooling fans.

Performance Data
Performance data is based on the European Standard EN12900. For operations at 60 Hz, performance values should be multiplied by 1.18. It is crucial not to mix ester oils with other types of oils. The document includes detailed tables of refrigerating capacity (Q) and power input (P) across various temperatures and models.

Key Performance Metrics
The tables provide refrigerating capacity and power input data for different evaporating temperatures, highlighting performance variations across different compressor models and conditions.
