HI RANGE for inverter use
The document discusses the benefits of using INVERTER systems with semi-hermetic motor compressors in refrigeration applications. Key advantages include energy savings, increased compressor reliability, reduced transient conditions, and noise reduction. The use of soft start inverters is recommended, particularly for supermarket refrigeration systems.
Complete Range
DORIN has developed a series of semi-hermetic compressors suitable for INVERTER applications, operating between 20Hz and 90Hz. These compressors, based on the H11, H35, and H41 series, are known for high C.O.P. values, low vibration, and pressure pulsation reduction. They feature an IP55 electric box, motor thermal protection, and parallel connection capability.
Application Limits
The document outlines operational limits for refrigerants such as R134a, R404A/R507, R407F/R407A, and R407C, providing specific performance data for each.
Performance Data
Performance data is provided for various refrigerants, detailing the efficiency and operational parameters of the compressors when used with INVERTER technology.
Overall Dimensions
Information on the physical dimensions of the compressors is included to ensure compatibility with existing systems and installations.
Test Results
A comparison test between systems with and without INVERTER technology shows significant energy savings, increased reliability, reduced transient conditions, and noise reduction. The test involved two systems, one for low temperature and one for medium temperature, both equipped with DORIN compressors.
Overview
Dorin has developed a range of semi-hermetic compressors designed to work with frequency converter technologies, operating over a wide frequency range from 20Hz to 90Hz due to a special design of the rolling parts.
Specifications
The compressors are similar to the previously tested H11, H35, and H41 series, maintaining high COP values, reduced vibration, and pulsation phenomena. They feature IP55 electrical enclosures, motor thermal protection using thermistors or Thermik, and can operate in parallel. Additionally, they have a specific electric motor for frequency converters and can operate from 20Hz to 90Hz due to a kinetic accumulator (patent pending).
Technical Characteristics
The document provides detailed technical data for various models, including displacement volume, net weight, and operating currents. The maximum allowable frequency is 75Hz, and the exact operating limits for each model should be referred to in the Dorin selection software.
Performance Data
Performance data is based on the European Standard EN12900. It is advised never to mix ester oils with different oils. The document includes performance data for different refrigerants like R134a, R407C, and R404A/R507, with tables showing power consumption and cooling capacity at various temperatures and frequencies.
Application Limits
The document outlines the application limits for different refrigerants, with graphs showing the relationship between evaporation and condensing temperatures. It also provides guidelines for standard operation and conditions requiring head cooling fans or maximum superheating.
Specifications
The document provides performance data for refrigeration systems using refrigerants R404A, R507, R407F, and R407A. The data is based on the European Standard EN12900. It includes tables of power input (P) in kW and refrigerating capacity (Q) in W across various evaporating temperatures ranging from +10°C to -40°C.
Procedures
It is emphasized that ester oils should never be mixed with different oils. For systems using R407A, a 6% reduction in both Q and P should be considered while maintaining the same Coefficient of Performance (COP).
Norms
The performance data adheres to the European Standard EN12900, ensuring consistency and reliability in the measurements provided.
Recommendations
Users are advised to strictly follow the guidelines regarding oil mixing and to adjust performance expectations when using R407A refrigerant.
Data Summary
The document includes extensive tables showing the relationship between power input and refrigerating capacity at different temperatures and frequencies. Key data points include:
- At +5°C, Q ranges from 2710 W to 53150 W, and P ranges from 0.61 kW to 14.46 kW.
- At -40°C, Q ranges from 190 W to 6250 W, and P ranges from 0.22 kW to 5.61 kW.
