Ejector Refrigeration Booster

Innovative method of improving system efficiency by overfeeding evaporators arranged in parallel in R744 (CO₂) refrigeration systems

A refrigeration unit for supermarkets and cold rooms with a plug & play design, simple and reliable

Description

A refrigeration unit for supermarkets and cold rooms
Improves system efficiency by overfeeding evaporators arranged in parallel in R744 (CO₂) refrigeration systems
Designed to recover energy contained in the high-pressure fluid exiting the condenser/ gas cooler

Basic specifications

Plug & play design
Uses CO₂ (R744), a zero environmental impact refrigerant
Available in Chilling (MT) and Booster (MT/LT) versions
Options available: parallel compressor, ejector recovering expansion, heat recovery and AC water chiller
Control algorithm continuously researches the maximum possible value of SET for suction pressure (SST – Saturated Suction Temperature) at actual load conditions

Advantages

Simple and reliable
Efficient operation even with high outdoor air temperature
Ejector liquid overfeeding improves efficiency compared to state-of-the-art products
Avoids presence of liquid at compressor suction, which is the most frequent cause of compressor breakdowns
Offers energy saving and smoother operating conditions
Maintains a simple plant lay-out, low refrigerant charge as well as a simple and trouble free design
Resilient towards liquid and oil slugs at compressors suction
System is available as an option on all the range of Enex units and it is fully compatible with controllers from leading manufacturers available on the market and with standard evaporators
