When considering the purchase of scroll compressors, various important factors play a pivotal role in ensuring you select the right model for your specific needs. Scroll compressors are widely recognized for their efficiency and reliability, making them a popular choice among manufacturers and HVAC professionals. Understanding these key considerations can lead to better operational performance and energy savings.

Efficiency Ratings
One of the primary factors to consider is the energy efficiency of a scroll compressor. Efficiency is usually represented by the coefficient of performance (COP) or energy efficiency ratio (EER). Higher ratings indicate better performance and lower operational costs. According to the U.S. Department of Energy, systems that use high-efficiency scroll compressors can achieve COP values above 4.0, leading to savings of up to 30% on energy costs compared to traditional systems.
Capacity Requirements
Selecting a scroll compressor that matches your application’s capacity needs is essential. Scroll compressors are available in various sizes, measured in tons of cooling. It’s crucial to assess the cooling load of your space accurately. According to the American Society of Heating, Refrigerating and Air-Conditioning Engineers (ASHRAE), over-sizing or under-sizing a compressor can lead to decreased efficiency and lifespan. A professional HVAC contractor can assist in calculating the required tonnage based on factors like square footage, insulation, and heat generation.
Refrigerant Type
The type of refrigerant used in the system is another key consideration. Scroll compressors typically operate with refrigerants such as R-410A and R-134A. It is essential to ensure that the refrigerant is compliant with environmental regulations. The transition to low-GWP (Global Warming Potential) refrigerants is a growing trend due to increasing environmental concerns. The Environmental Protection Agency (EPA) suggests that manufacturers and consumers stay informed about alternative refrigerants as phasedown regulations evolve.
Durability and Reliability
Durability is a vital consideration when selecting scroll compressors. A well-constructed scroll compressor can last for 15 years or more with appropriate maintenance. Research from the Air-Conditioning, Heating, and Refrigeration Institute (AHRI) indicates that better quality compressors lead to fewer service calls and less downtime. Always consider purchasing from reputable scroll compressor suppliers who provide warranties and after-sales support.

Noise Levels
Noise pollution in industrial and commercial environments can reduce productivity and comfort. Modern scroll compressors are designed to operate quietly, with many models producing sound levels below 60 dBA. Selecting a compressor known for low noise operation can be beneficial in applications such as hospitals, schools, and residential areas. Checking manufacturer specifications for sound ratings is advisable when purchasing.
Installation and Maintenance
Another consideration is the installation and ongoing maintenance requirements of the scroll compressor. Proper installation is crucial for optimal performance. It’s recommended to engage certified technicians for installation, which ensures compliance with safety and efficiency standards. Additionally, while scroll compressors generally require less maintenance than reciprocating compressors, regular inspections and servicing are still essential to prolong the equipment’s life and maintain efficiency.
Cost and Budget
Cost is often a significant factor in any purchasing decision. While scroll compressors may have a higher initial price point compared to other types, their long-term operational savings and lower maintenance costs often make them a more economical choice in the long run. According to the Building Energy Efficiency Frontiers (BEEF) report, investing in high-efficiency compressors can lead to a return on investment (ROI) within 2-3 years based on energy savings.
Supplier Reputation and Support
Lastly, choosing reliable scroll compressor suppliers is vital. Look for suppliers with a strong market presence and positive customer reviews. Consider their customer service quality, warranty options, and availability of replacement parts. Suppliers that provide comprehensive support and technical assistance can make a significant difference in the longevity and performance of the compressor.
In summary, carefully evaluating these key considerations can help ensure you choose the best scroll compressor for your needs. Understanding factors such as efficiency, capacity, refrigerant type, durability, noise levels, installation, cost, and supplier reputation will lead to informed decisions that enhance your system's performance and efficiency. Integrating this knowledge will not only assist users but also facilitate better operational practices by leveraging reliable scroll compressor suppliers.
