Double stage semi-hermetic compressors 50/60Hz

Product catalog summary

Overview: The document details the specifications and features of Frascold's semi-hermetic double-stage compressors, compatible with refrigerants R404a, R507, and R22, emphasizing efficiency and reliability.

Main Features:

Quiet and smooth operation due to optimal mass distribution.
Enhanced durability with specific heat treatment for shafts and optimized piston shapes.
Reduced friction and oil circulation with chromium-plated rings.
Reversible oil pump lubrication for V and Z series.
Improved efficiency with specially sized valve plates.
High-efficiency electric motor with overheating protection.

Standard Equipment:

Suction and discharge valves with sweat connections.
Rubber vibration absorbers and lubricant charge.
Nitrogen holding charge to prevent humidity.
Oil sight glass and electronic protection module for high discharge temperatures (V and Z series).

Accessories: Optional accessories include a liquid subcooling kit and crankcase heater. High discharge temperature protection is available for the S series.

Electrical Protection: All compressors are equipped with PTC thermistors in the motor stator, linked to an electronic control module. V and Z series have additional discharge gas temperature protection.

Technical Data: Detailed tables provide technical specifications such as power input, displacement, and electrical data for various models and conditions.

Technical Document Summary:

1. Specifications: Detailed specifications for compressors using refrigerants R404a, R507, and R22, including power consumption and refrigerating capacities under various conditions.

2. Procedures: Conditions for calculating refrigerating capacities include a power supply of 50Hz or 60Hz, ambient temperature of 32°C, and suction gas temperature of 20°C, with and without liquid subcooling.

3. Standards: Refrigerating capacities are presented in watts (W) based on standardized conditions, with tables ensuring compliance with industry standards.

4. Recommendations: For accurate calculations, refer to specific conditions such as the absence of liquid subcooling and specified ambient and suction gas temperatures.

5. Data Interpretation: Tables provide refrigerating capacities at various evaporating temperatures (-20°C to -50°C) and condensing temperatures (30°C to 50°C), aiding in compressor model selection.

6. Key Parameters: Critical parameters include evaporating temperature (te), condensing temperature (tc), and refrigerating capacity (W), essential for determining compressor efficiency and suitability.

7. Limitations: Additional considerations or calculations may be required for R507 refrigerant, as indicated on page 12.
