Une nouvelle architecture de surpresseur à spirale distribuée pour les systèmes frigorifiques des supermarchés.

A novel distributed scroll booster architecture for supermarket refrigeration.

Numéro : 2494



Today’s supermarket system architectures are being designed to minimize global warming potential (GWP) fromboth direct and indirect carbon emissions. To achieve this, many supermarkets are primarily employing one of twoleading strategies:
(1) designing and using systems that require smaller refrigerant charges, such as self-contained,secondary, or distributed systems; and
(2) using lower-GWP refrigerants such as CO2 in a transcritical system.

While both strategies have proved effective, each approach leaves room for improvement.The purpose of this paper is to introduce a third strategy: utilizing a distributed scroll booster system as an emergingalternative for distributed systems. The distributed scroll booster is configured to leverage A1 (R-134a like), lowpressurerefrigerants, which enable several key benefits:
- Reduced refrigerant charge
- Higher system efficiencies
- Ability to use common refrigerants and components with which technicians are familiar
- Lower leak rates
- Future compatibility with A2L refrigerants such as R-516A and R-1234yf which have lower GWPs whencodes and standards are updated

This paper will introduce how these benefits are realized through the system’s design. It will cover strategies tomanage:
- Use of low-pressure refrigerants in the distributed scroll booster
- Design flexibility and reliability of the distributed scroll booster
- Reducing the strain on compressors through the distributed scroll booster.
