Air-cooled chillers operating with R290 refrigerant offer unparalleled performance for both process and comfort cooling. Let's look at the advantages of designs featuring scroll compressors, the merits of employing R290 as a refrigerant, and the scenarios in which these chillers with R290 could be the optimal choice for your application.

The advantages of scroll compressors
Scroll compressors offer several advantages, including:
1. Higher efficiency: Scroll compressors are engineered to provide superior energy performance, reducing operational costs. For instance, the efficiency at full load has increased by as much as 20% compared to the previous generation, positioning the new Trane Aries model ASCO as the leader in its R290 air-cooled chiller class.
2. Reduced maintenance: With few moving parts, scroll compressors are less prone to wear and tear, resulting in lower maintenance requirements and maximum uptime, particularly important in mission-critical process applications.
3. Quieter operation: Scroll compressors operate more quietly than other compressor technologies, making them ideal for noise-sensitive environments.

Trane’s new Aries N model ASCO series marks a significant upgrade from its predecessors by incorporating scroll compressors in a completely enhanced platform.

In addition to the impressive full load performance, the Trane Aries N model ASCO achieves an average SEER of 5.0 for comfort cooling and an average SEPR HT of more than 6.4 for process cooling with higher temperatures.


The benefits of R290 as a refrigerant
This refrigerant offers several benefits for building owners, facility managers, and end users.
1. Low environmental impact: R290 is a sustainable choice for those who focus on reducing greenhouse gas emissions and decarbonizing their operations.
2. High efficiency: R290 positively contributes to the overall efficiency of the chiller, leading to lower energy consumption and operational costs.
3. Safety measures: Trane addresses concerns about flammability and ensures safety with its SDS2E system (Segregate, Detect, Stop, Signal, and Extract) protocols.

 
When to consider air-cooled scroll chillers with R290 for your application
Here are some scenarios where air-cooled scroll chillers with R290 might be the ideal choice:
1. Eco-conscious operations: If your business prioritizes sustainability and reducing environmental impact, R290 is an excellent choice due to its negligible GWP. These types of applications could be air conditioning for public institutions, hotels or offices, to name a few.
2. High-efficiency requirements: For applications demanding high efficiency and low operational costs, R290-enhanced chillers offer superior performance. Examples include energy-intensive process cooling applications like the food & beverage industry, the pharmaceutical industry and die cast manufacturing applications.
