Tandem semi-hermetic compressors 50-60 Hz

Product catalog summary

Standard Equipment: The compressors come with essential components such as suction and discharge valves, a frame, crankcase pressure equalization line, oil level equalization line, rubber vibration absorbers, oil lubrication charge, sight glasses, and a nitrogen charge for humidity protection. The VV, ZZ, and WW series include additional features like oil pumps and electronic oil pressure switches. Optional accessories are available for improved efficiency and reliability. All models are coated with anti-rust primer and blue enamel.

Electric Motors: Detailed electric characteristics and performance data for motors are available, with specific information on pages 30 and 31. For different voltage requirements, contact the Technical Department.

Protection Devices: Compressors are equipped with PTC thermistors in the motor stator, linked to an electronic control module (KRIWAN INT69 for QQ and SS series; KRIWAN INT 69 TM for VV, ZZ, and WW series). The VV, ZZ, and WW series also feature discharge gas high-temperature protection.

Lubrication: The QQ and SS series utilize oil thrower disc lubrication, while the VV, ZZ, and WW series employ high-pressure oil pumps with oil filters and electronic oil pressure switches.

Refrigerating Capacity: Capacities are based on conditions without liquid subcooling, an ambient temperature of 32°C, and a suction gas temperature of 20°C, following EN12900 standards. Conversion factors are provided for calculating actual refrigerating capacity based on specific condensing and evaporating temperatures.

Technical Data: The document includes detailed technical data such as cylinder numbers, packing volume, lubricant volume, displacement, electric motor specifications, and weights for various compressor models.

Overview: This document provides detailed technical specifications and performance data for refrigeration compressors, specifically models ZZ, WW, QQ, SS, and VV, operating with refrigerants R22 and R134a. The data includes refrigerating capacities at various evaporating and condensing temperatures.

Specifications:

Refrigerants: R22 and R134a.
Frequency: 50 Hz.
Models: ZZ, WW, QQ, SS, VV.

Performance Data:

Refrigerating Capacity: Provided in watts (W) for different evaporating temperatures ranging from 12.5°C to -20°C. Additional data for -25°C and -30°C available upon request.
Condensing Temperature: Data provided for various condensing temperatures, indicating performance variations.

Cooling Methods:

Head cooling and liquid injection cooling methods are discussed, highlighting their impact on compressor performance.

Key Observations:

Performance varies significantly with changes in evaporating and condensing temperatures.
Specific models are optimized for different temperature ranges and cooling methods.

Recommendations:

Choose the appropriate compressor model based on the specific temperature requirements and cooling method.
Consider additional data for extreme temperature conditions (-25°C and -30°C) if applicable.

Overview: This document provides detailed technical specifications and data on refrigerating capacities for various compressors under different conditions. It includes tables with refrigerating capacities at different evaporating and condensing temperatures, specifically for refrigerants R404A and R507A.

Key Sections:

Evaporating Temperature: The document lists evaporating temperatures ranging from 12.5°C to -45°C, with corresponding refrigerating capacities.
Refrigerating Capacity: Tables provide refrigerating capacities in watts for different condensing temperatures (30°C to 80°C) and evaporating temperatures. Capacities are given for both R404A and R507A refrigerants.
Condensing Temperature: Data is provided for condensing temperatures from 30°C to 80°C, showing how refrigerating capacity changes with temperature.
Head Cooling: The document mentions configurations with head cooling, which affects the refrigerating capacity.
Additional Capacities: Capacities at -25°C and -30°C are available upon request, indicating the document's flexibility in providing additional data as needed.

Data Interpretation: The tables illustrate how refrigerating capacity decreases as the evaporating temperature decreases and as the condensing temperature increases. This is critical for understanding the performance of compressors under varying operational conditions.

Recommendations: For specific refrigerating capacities using R507A, calculations should be performed as indicated on page 4 of the document. This suggests that users need to refer to additional instructions for precise data.

Conclusion: The document serves as a comprehensive guide for selecting and understanding the performance of compressors based on refrigerating capacities at various temperatures. It is essential for engineers and technicians working with refrigeration systems to ensure optimal performance and efficiency.

Overview: This document provides technical specifications and component descriptions for compressors, focusing on various parts and their functions. It includes dimensional drawings and component lists in multiple languages.

Key Components:

Oil Filter with Magnetic Plug: Designed to capture metallic particles, enhancing the filtration process.
Max Discharge Temperature Sensor: Monitors the maximum temperature of the discharge to prevent overheating.
Electronic Oil Pressure Switch Connection: Facilitates the connection of electronic oil pressure switches for monitoring purposes.
Crankcase Pressure Equalizer: Balances the pressure within the crankcase to ensure optimal operation.
Oil Level Equalizer: Maintains consistent oil levels across the system.

Dimensional Specifications: The document includes detailed measurements for various compressor models, specifying length, width, height, and mounting dimensions. These are crucial for installation and integration into existing systems.

Valves and Connections:

Suction Valve (SV): Controls the intake of refrigerant into the compressor.
Discharge Valve (DV): Manages the release of compressed refrigerant from the compressor.
High and Low Pressure Connections: Provide interfaces for connecting to high and low-pressure lines.

Additional Features:

Oil Drain and Return Plugs: Facilitate maintenance by allowing easy draining and refilling of oil.
Liquid Injection Sensor and Valve Plugs: Used for monitoring and controlling liquid injection processes.

Manufacturer Information: The compressors are produced by Frascold Spa, located in Rescaldina, Italy. Contact details and website information are provided for further inquiries.
