Scroll Compressors are a traditional form of compressors which are mainly used in refrigeration and cooling systems. Scroll air compressors are ideal for continuous airflow for a long period which is a higher demand in both personal and commercial environments.
The Danfoss SM-185S4VC is a hermetic scroll compressor
1. Compressor Type and Technology:
Scroll Compressor: The SM-185S4VC utilizes scroll technology, which involves two intermeshing spiral-shaped scrolls one stationary and one orbiting. This design offers several advantages:
High Efficiency: Continuous compression process minimizes re-expansion losses.
Quiet Operation: Smooth, continuous motion results in lower noise and vibration compared to reciprocating compressors.
High Reliability: Fewer moving parts than other compressor types lead to enhanced durability and longer lifespan.
High Resistance to Liquid Slugging: The gas intake design is engineered to better handle instances of liquid refrigerant entering the compressor.
2. Refrigerant Compatibility:
R22: The SM-185S4VC is designed to operate with R22 refrigerant. It can also be used with R417A-160SZ.
Mineral Oil (160P): It is charged with mineral oil, specifically 160P, which is compatible with R22.

4. Electrical Characteristics:
Super advantages:
? High- performance
Less the host of the scroll air compressor parts , piston machine 1/8 , a key factor in a significant reduction of parts to improve the reliability .
Small turning radius , the line speed is less than 2m / s , and thus low-friction , high mechanical efficiency .
? Low noise
Piston , screw compressor compared to the lowest noise only 50 db . No smoke, exhaust valve eliminates the percussion sound of the valves and the explosion , so that the noise extremely lower .Suction and discharge is continuous and stable machine vibration small , small body size , small area , can be installed in any place , save a large amount of pipe and installation and management costs , and environmentally friendly performance .
? The scroll compressor is the minimum energy consumption in the current third-generation compressor
Because inspiratory booster effect and clearance volume , volumetric efficiency of the vortex air compressor up to 1 times or more , while the piston volumetric efficiency is about 70% , the lowest screw .No suction , exhaust valve, the resistance loss is almost zero , which is a scroll air compressor air compressor efficiency than other types of substantial energy saving of the main reasons .
? Low maintenance costs
The novel host structure , fewer parts, no contact , precision difficult to damage , and replacement parts long life cycle , significantly reducing the possibility of replacement parts and damage . Failure rate is extremely low , very smooth running , because the parts linear speed less than 2m / s . Although the scroll compressor in the world only a few countries have , in this technically is very mature, models and more comprehensive , it is the best similar products to replace the piston and screw compressors choice.
? The advantages of compressor control table of scroll type.
The piston machine has more wearing parts and it is noisy , high maintenance cost and short life is an accepted fact also.
Screw machine has the high precision machining , processing costs , a cost advantage in the small displacement range .
Scroll machine with low noise , smooth operation , high reliability, less maintenance costs , energy saving and environmental protection .
1.Super energy saving
Save electricity more than 10000/y
2.Low noise level
Non-contact and low noise of, quiet operation
3.Low maintenance cost
No wearing parts, less consumable components, reliable and durable
4.Direct coupling drive
No efficiency loss and no belt maintenance
