HI SERIES

Product catalog summary

Introduction
The document highlights the benefits of using inverter systems with semi-hermetic motor compressors in refrigeration applications. Inverter technology is praised for its energy efficiency, enhanced compressor reliability, reduced transient conditions, and noise reduction. The HI range of compressors by Officine Mario Dorin is specifically designed for variable frequency operation and is compatible with any market inverter that meets technical bulletin BT010 requirements.

Complete Range
The HI compressor range is an evolution of the H series, maintaining high Coefficient of Performance (C.O.P.) values, low vibration, and reduced pressure pulsation. These compressors operate between 20Hz and 90Hz and feature a specific kinetic accumulator (patent pending) with an optional dedicated inverter.

Application Limits
The document specifies application limits for various refrigerants, including R134a, R450A, R513A, R452A, R449A/R448A, R407F/R407A, R404A/R507, and R407C, each with specific performance data and guidelines.

Performance Data
Performance data for different refrigerants are provided, detailing operational parameters and efficiency metrics for each type.

Overall Dimensions
Information on the overall dimensions of the compressors is included to ensure compatibility with various installation requirements.

Test Results
Comparison tests between systems with and without inverters show significant energy savings, increased reliability, reduced transient timeframes, and noise reduction. The tests involved systems for both low and medium temperatures, equipped with Dorin compressors.

Conclusion
The HI range compressors are optimized for inverter applications, offering significant advantages in energy efficiency and operational reliability, making them suitable for supermarket refrigeration systems and similar applications.

Performance Specifications
The document provides performance data for refrigeration systems based on the European Standard EN12900, emphasizing the importance of not mixing ester oils with different oils to maintain system integrity.

Refrigerant Types
Data for refrigerants R452A, R449A, and R448A is included. For R448A, a 1% reduction in performance (Q and P) is noted, while maintaining the same Coefficient of Performance (COP).

Performance Data
Performance data is presented in tables showing refrigerating capacity (Q) in watts and power input (P) in kilowatts across various evaporating temperatures from +5°C to -40°C, organized by different models and series.

Key Observations
- Refrigerating capacity and power input vary significantly with changes in evaporating temperature and frequency.
- Higher frequencies generally result in higher refrigerating capacities and power inputs.
- Detailed performance metrics for each model allow for precise selection based on specific cooling requirements.

Recommendations
- Ensure compliance with EN12900 standards for accurate performance assessment.
- Avoid mixing different types of oils to prevent system inefficiencies or damage.
- Consider the slight performance reduction when using R448A refrigerant.
