CO2 Transcritical Semihermetic Compressors

Product catalog summary

Introduction
The document introduces the CD series of semi-hermetic CO2 compressors, specifically designed for transcritical applications. These compressors utilize advanced design techniques to handle extreme conditions, focusing on optimizing heat transfer for high efficiency and COP values. They are built to withstand high pressures of 100 bar and 150 bar.

Technical Data
Technical specifications include details on displacement, operating current, and locked rotor current for various models. The compressors are categorized by evaporating temperature capabilities: high (H), medium (M), and low (B). Detailed tables provide information on displacement, suction, discharge, net weight, and oil charge for each model.

Application Limits
This section outlines the operational boundaries, including pressure limits and temperature ranges, ensuring safe and efficient use of the compressors.

Accessories
A list of available accessories is provided to enhance the functionality and integration of the compressors into different systems.

Performance Data
Performance data illustrates the efficiency and capacity of the compressors under various conditions, including power consumption and cooling capacity.

Overall Dimensions
Dimensions are detailed to assist in planning and installation, covering both single and two-stage compressors.

Conclusion
The CD series offers a comprehensive range of CO2 compressors with displacements from 1.12 m3/h to 30.50 m3/h at 50 Hz.

Specifications
The document is based on the European Standard EN12900, specifying performance data for a frequency rate of 50 Hz. For 60 Hz operations, data should be multiplied by 1.18. It is crucial not to mix ester oils with other oils.

Performance Data
Detailed performance data is provided for various models and conditions, including refrigerating capacity (Q) in watts and power input (P) in kilowatts across different evaporating temperatures.

Operating Conditions
Operating conditions are specified in terms of evaporating temperature, with tables showing refrigerating capacity and power input for each condition. Adhering to these conditions ensures optimal performance.

Recommendations
Recommendations include maintaining the specified frequency rate of 50 Hz and adjusting performance data for 60 Hz operations. It also advises against mixing different types of oils.
